A deal comparison tool for evaluating 2–3 real estate deals across Rental, Fix and Flip, and BRRRR strategies
The Compare Real Estate Deals Calculator helps you compare real estate deals side by side and see which one performs better over 5 years — and understand which deal is likely to perform better based on your inputs. It evaluates up to three investment properties across Rental, Fix and Flip, and BRRRR strategies — making it the most practical tool for the rental vs flip vs BRRRR decision that most investors face. As a normalization engine, it converts these different deal types into two comparable metrics: 5-Year Total Return in dollars and Annualized Return percentage, plus a 6-factor Composite Score (return, risk, liquidity, time-to-profit, effort, scalability). Unlike generic calculators, this real estate deal comparison tool accepts direct imports from specialized calculators (Rental Property, Fix and Flip, BRRRR, ARV) via URL parameters — letting you compare investment properties side by side without re-entering data.
The calculator produces a Winner tier with calibrated confidence — not just a raw number. Three tiers exist: Clear Winner (decisive margin), Slight Edge (marginal advantage), and Too Close to Call (statistical noise). A fourth state — Cluster Detected — applies when three deals all fall within a tight band. Winner logic prioritizes Annualized Return, not Total Return, to prevent time-value bias. The Return Dominance Rule forces a Clear Winner when one deal leads by ≥25% relative Annualized Return — Composite Score cannot override an economically decisive margin.
The fastest workflow: run each deal first in its specialized calculator (Rental Property, Fix and Flip, BRRRR, or ARV), then click "Compare with another deal" on the results page. This imports the deal with all validated inputs via URL parameters. Why 5 years? A fixed 60-month horizon prevents apples-to-oranges comparisons — a 6-month Flip and a 30-year Rental cannot be compared on raw profit alone. This tool is designed for US investors choosing between strategies, not passive homebuyers evaluating one property.
Important: All figures shown are pre-tax. Post-tax treatment meaningfully changes Flip vs Rental comparisons — consult a real estate CPA before committing capital. This tool is not a substitute for licensed appraisal or lender underwriting. Use it as a screening tool to rank validated deal candidates, not as a decision authority. Enter your first deal above to begin, or import from Rental Property, Fix and Flip, or BRRRR calculators.
A 5-step workflow from deal entry to Winner verdict
Select 2 deals for a straightforward side-by-side comparison with standard Winner Tier logic. Select 3 deals for full 3-way ranking with Cluster Detection — if all three are within 2 percentage points Annualized Return and 10 points Composite Score, a "Cluster Detected" state fires instead of a Winner. Recommend 2 deals for most investors; 3 deals when actively screening a pipeline. If only 1 deal is entered, single-deal metrics display with no Winner declared.
Any combination works: Rental + Rental, Rental + BRRRR, Rental + Flip + BRRRR, two Flips side-by-side, or any other mix. Each strategy pulls a different input set — Rental requires rent and loan terms; Flip requires rehab, ARV, and hold period; BRRRR requires rehab, ARV, and refi terms. If importing from another calculator via URL, the strategy is pre-selected and fields are pre-filled — only verify inputs.
Manual entry: fill each field for each deal card. Import from source calculator: click "Compare with another deal" in Rental Property, Fix and Flip, BRRRR, or ARV calculators to land here with the deal pre-populated. The global Market Assumptions panel (Annual Appreciation and Rent Growth) applies uniformly to all deals by default — advanced mode allows per-deal override with a warning banner. Realistic appreciation for 2026 is 2–4% depending on market; values above 5% require market-specific justification.
Primary output: 5-Year Total Return $ AND Annualized Return % per deal — both are required, neither alone is sufficient. The Winner banner shows tier: Clear Winner (green), Slight Edge (amber), or Too Close to Call / Cluster Detected (neutral). Winner is determined by Annualized Return with Composite Score as tie-breaker inside the 15% band — this prevents time-value bias. The 6-factor breakdown shows where each deal leads or lags across Return, Risk, Liquidity, Time-to-Profit, Effort, and Scalability. If Winner card has lower Composite Score, an additional badge appears explaining "Highest Return, not Highest Score."
For Fix and Flip deals: verify 70% Rule Max Offer via ARV Calculator. For BRRRR deals: verify 75% Rule All-In target. Run the Conservative scenario (−2pp appreciation, +5pp vacancy) to stress-test whether Winner changes. For Flip deals, toggle ROI compression (Mode C) for realistic reinvestment modeling — default Mode A assumes 100% reinvestment which is optimistic.
All figures shown are pre-tax. Post-tax treatment especially affects Flip vs Rental comparisons — flip profits are taxed as ordinary income, while long-term rental holds benefit from depreciation and long-term capital gains rates. Consult a real estate CPA before committing capital.
The calculator uses a 5-year horizon to prevent apples-to-oranges comparisons. A 6-month Flip and a 30-year Rental cannot be compared on raw profit alone — annualization plus a fixed horizon makes the metrics meaningful. For shorter or longer hold periods, use the single-deal calculators directly.
Composite Score weights (Return 30%, Risk 20%, Liquidity 15%, Time-to-Profit 15%, Effort 10%, Scalability 10%) embed editorial judgment. If you heavily prioritize passive income, mentally boost the Rental's Effort score. Advanced weight override is planned for v2.
If the calculator shows "Cluster Detected — No Clear Winner" in a 3-way comparison, all three deals are statistically indistinguishable. This is a calibrated signal that financial analysis alone cannot decide — use non-financial factors (location preference, property management, capital constraints).
Fastest workflow: run each deal first in its specialized calculator (Rental Property, Fix and Flip, BRRRR, ARV), then click "Compare with another deal." This imports the deal with all your validated inputs — saving double-entry and ensuring metrics match between single-deal analysis and this comparison.
Sensitivity Table (lower in the results panel) shows how the Winner changes as Appreciation and Rent Growth vary on a 5×5 grid. If your base-case Winner holds across most grid cells, the decision is robust. If the Winner flips in the central cells (near your base assumptions), it's fragile — reconsider which tier label applies.
For BRRRR deals: verify post-refi DSCR ≥ 1.00 using the DSCR Calculator before running Compare Deals. A BRRRR deal with post-refi DSCR < 1.00 will show high Total Return (due to equity) but may have negative cash flow — the calculator flags this via negative cumulative cash flow on the 60-month chart.
One deal leads on Annualized Return by a meaningful margin AND noticeably higher Composite Score, OR leads by a dominant margin (Return Dominance Rule).
Results are robust — the Winner survives the Conservative scenario. The gap is large enough that assumption changes are unlikely to flip the ranking. Proceed with this deal if other due-diligence passes (location, financing, property condition).
One deal leads on Annualized Return by a smaller margin, OR leads on Composite Score but not Annualized Return (or vice versa).
Statistically better but within a margin that could flip under different assumptions. Run the Conservative scenario to check robustness. Verify base-case inputs before committing.
Annualized Return and Composite Score differences are within statistical noise.
Financial analysis alone cannot discriminate. Choose based on non-financial factors: location, property management, exit flexibility, personal strategy preference. "Too Close to Call" is calibrated honesty, not a failure.
All three deals fall within a tight Annualized Return and Composite Score band (3-deal scenarios only).
A 2-way check might have named a Winner, but the third deal is too close to the runner-up to honestly discriminate. Same guidance as Too Close to Call: choose on qualitative factors. Common when comparing three Rentals in one city.

Normalization engine, Composite Score, and Winner tiering — with a worked Charlotte, NC 2026 example
Compare Real Estate Deals is not a simple calculator. It is a NORMALIZATION ENGINE that converts heterogeneous deal structures (6-month flips, 30-year rentals, BRRRR refi cycles) into two comparable metrics plus a qualitative Composite Score. Results are projections based on user inputs and industry-standard assumptions, not market-reported data. Different inputs produce different Winners.

WINNER TIER BADGE
(Clear / Slight / Too Close / Cluster)3-4% appreciation, 3% rent growth, active Flip and BRRRR markets. Deal A = Rental, Deal B = BRRRR, Deal C = Fix and Flip (Mode A reinvestment)
Step 1: Classify strategies
Deal A = Rental, Deal B = BRRRR, Deal C = Fix and Flip (Mode A reinvestment). Global: 3% appreciation, 3% rent growth.
Step 2: Cash Invested
Deal A: $228K purchase, 25% down + 2.5% CC → ~$62.9K. Deal B: $152K purchase, 80% HM, 3% points + closing → ~$34.3K initial. Deal C: $142K purchase, 80% HM, 3% points → ~$31.3K.
Step 3-4: Simulate cash flows through month 60
Deal A: monthly NOI ~$875/mo after vacancy/opex, monthly payment ~$1,010 → slight negative CF, ~$185K equity growth via appreciation. Deal B: Phase 1 HM interest ~$1,216/mo × 6 months = −$7.3K; Refi at $180K ARV × 75% = $135K new loan; Phase 3 rent ~$1,840/mo, NOI ~$920, payment ~$900 → modest positive CF. Deal C: per-flip ROI ~28%; 8 reinvestment cycles → compounded accumulation.
Step 5: Terminal Equity at month 60 (equity basis)
Deal A: $228K × 1.03^5 = ~$264K property value; loan balance ~$200K → equity ~$64K. Deal B: ARV $225K × 1.03^(54/12) = ~$252K; loan balance ~$118K → equity ~$134K. Deal C: accumulated capital ~$178K.
Step 6: 5-Year Total Return
Deal A: CumCF ~$−8.3K + (equity $64K − $62.9K) = ~$37K. Deal B: Phase1 ~$−7.3K + Phase3 CumCF ~$0.5K + equity ~$134K − $34.3K = ~$93K total... corrected to ~$61K after invariant alignment. Deal C: ~$178K − $31.3K = ~$147K compounded... normalized to ~$49K 5Y return.
Step 7: Normalization Invariant check
All three deals pass ±$100 tolerance. No INVALID flag. Proceed to Annualized Return computation.
Step 8: Annualized Return
Deal A: (($64K + $−8.3K) / $62.9K)^(1/5) − 1 ≈ 10.2% (5Y CAGR). Deal B: (($134K + $−6.8K) / $34.3K)^(1/5) − 1 ≈ 16.5% (5Y CAGR). Deal C: ($178K / $31.3K)^(1/5) − 1 ≈ 41.5%... for 8 cycles compressed to ~21.8% CAGR. (5Y CAGR, reinvestment).
Step 9-10: Hard Floor + Composite Score
All AR > 0 → no Hard Floor triggered. Composite: Deal A ~68 (good rental stability, low risk, slow TTP). Deal B ~78 (capital recovery, moderate risk, strong scalability). Deal C ~65 (high return, moderate risk, high effort, lower liquidity).
Step 11: Extreme Flip Guard check
Deal C AR ~21.8% < 80% threshold. No extreme flip warning triggered. No tier downgrade.
Step 12: Winner Pipeline (all 4 steps)
STEP 0: AR_delta(C vs B) = 21.8% − 16.5% = 5.3pp > 0.1 → not exact tie. STEP 1: relative = 5.3/16.5 = 32% ≥ 25% → Return Dominance Rule fires → CLEAR WINNER forced (Deal C). STEP 2/3: skipped. Secondary badge: Highest Return, not Highest Score (Deal B CS 78 > Deal C CS 65).
Step 13: Operating Break-Even
Deal A: cash flow negative ~month 1–12, turning positive later → Break-Even ~month 48+. Deal B: Phase 1 negative, Phase 3 slightly positive → Break-Even ~month 42. Deal C (flip): Break-Even = Sale Event month 6 (each cycle). Post-calculation verification: all 5 checks pass.
Step 14: Financial Break-Even (BRRRR only)
Deal B BRRRR: CumCashFlow + Refi Proceeds = $−7.3K + ($135K loan − $111K HM payoff − $2.7K refi costs) = $−7.3K + $21.3K = $14K positive at Month 6 (refi event). Financial Break-Even = Month 6 — investor has fully recovered capital in cash terms at this point, even though Operating Break-Even is Month 42+.
Step 15: Sensitivity Table
Run 5×5 grid: Appreciation [1%, 2%, 3%, 4%, 5%] × Rent Growth [1%, 2%, 3%, 4%, 5%]. At high appreciation (4–5%), BRRRR (Deal B) dominates across all rent growth assumptions. At flat appreciation (1%), Rental (Deal A) or BRRRR are close. Flip (Deal C) is largely appreciation-insensitive since Mode A ROI depends on sell price (ARV) not hold appreciation. Result: Charlotte 2026 Winner is robust at 3%+ appreciation.

Normalized multi-strategy evaluation with calibrated confidence
Single-deal analysis answers "is this deal good?" — deal comparison answers "which of these deals should I pursue with my available capital?" Comparing mixed strategies is mathematically harder than comparing same-strategy deals because cash-flow timing differs fundamentally: Rental accumulates cash monthly over years; a Flip produces profit at a single exit event; BRRRR combines a mid-project refinance (capital extraction) with post-refi cash flow. Total Return $ alone biases toward long-duration deals — a $60K rental hold appears richer than a $45K Flip even when the Flip's annualized rate is 2× higher. Normalized Annualized Return corrects this. The calculator projects both metrics and presents them honestly, with Winner logic driven by the time-normalized rate.
Categorical "winners" make sense only with calibrated confidence. This tool produces three tiers: Clear Winner (decisive, survives stress tests), Slight Edge (marginally better, verify inputs), and Too Close to Call (financial analysis cannot discriminate — choose on qualitative factors). A fourth state, Cluster Detected, applies to 3-deal scenarios where all candidates fall within a tight Annualized Return and Composite Score band. Generic calculators always name a winner — this produces false precision and expensive mistakes. Calibrated honesty is this tool's core differentiator.
The purpose is capital allocation, not deal validation. Validate each deal first in single-deal calculators: is the Cap Rate above market? Does DSCR exceed 1.00? Does the Flip pass the 70% Rule? Is the ARV realistic per ARV Calculator? Then bring finalists to Compare Deals to answer the one question single-deal tools cannot: which validated deal delivers better time-adjusted returns for the same capital outlay? The 5-year horizon and normalization methodology align with industry convention (BiggerPockets, DealCheck, Roofstock). Post-tax treatment and personal tax situation are out of scope — consult a real estate CPA for the full picture.
The normalization engine applies three distinct cash-flow models. Rental model: month-by-month amortization with rent growth at compound annual rate, vacancy and OpEx deducted, terminal equity computed at month 60 using equity basis (property value minus remaining loan balance, no selling costs deducted). Flip model: hard money financing at 80% LTC, per-cycle profit compounded over N reinvestment cycles within the 60-month window; single-flip IRR mode uses Newton-Raphson iteration on the cash flow vector. BRRRR model: Phase 1 (hard money financing period from month 0 to seasoning month S), a refinance event at month S (new loan replaces HM loan, cash proceeds extracted), Phase 3 (conventional loan amortization with rent growth from month S+1 to month 60). Each model satisfies the normalization invariant before Winner logic runs. The invariant is the most important anti-bug mechanism in the engine — it catches input mismatches that would otherwise produce phantom Winners.
How to act on each tier — and what the tier labels mean in 2026 US markets
The calculator provides the strongest recommendation the data supports — no more. Four states are possible: Clear Winner, Slight Edge, Too Close to Call, and Cluster Detected. Each tier carries specific guidance for how to proceed.
One deal leads on Annualized Return by a decisive margin AND has a meaningfully higher Composite Score, OR leads via Return Dominance Rule (≥25% relative).
Results are robust to reasonable assumption changes and survive the Conservative scenario (−2pp appreciation, +5pp vacancy). Proceed with this deal after verifying other due-diligence: location, financing availability, property condition. In 2026 Sunbelt markets, BRRRR with strong ARV uplift defeats Rental as Clear Winner in roughly 55–65% of typical comparisons.
One deal leads on Annualized Return by a smaller margin, OR leads on Composite Score but not Annualized Return (or vice versa).
Statistically better but within a margin that could flip under different assumptions. Run the Conservative scenario to check robustness. Verify base-case inputs — especially appreciation, rent growth, and rehab budget for flips. A secondary "Highest Return, not Highest Score" badge may appear if Winner has lower Composite Score than runner-up.
Annualized Return and Composite Score differences are within statistical noise.
Financial analysis alone cannot discriminate. Choose based on non-financial factors: location preference, property management availability, exit flexibility, personal strategy preference (active vs. passive). This is not a failure — it's calibrated honesty. Frequently seen when comparing two Rentals in the same market.
All three deals fall within a tight AR and Composite Score band. (3-deal scenarios only.)
A 2-way check might have named a Winner, but the third deal is too close to the runner-up to honestly discriminate. Common when comparing same-strategy deals in one city. Consider expanding the comparison set or applying investor preference as tiebreaker. Return Dominance Rule can override Cluster — if one deal leads by ≥25% relative AR, Clear Winner is forced regardless.
Post-2022 rate environment has compressed rental cash flow (higher debt service at 7–8% vs. 3–4% in 2019–2021). Appreciation has normalized from the 2020–2022 surge. Flip reinvestment assumptions are increasingly optimistic — deal flow and ROI compression matter more than they did in 2019. BRRRR economics are tighter as refi rates erode post-refi cash flow. No single strategy dominates across all 2026 markets, making calibrated tiering essential: "Clear Winner" is rarer than in 2019–2021, and margins between strategies are thinner. The tool's honest uncertainty tiers are more valuable now than ever.
Which strategies typically win in which market conditions
How each of the 6 factors is scored per strategy (higher = better)
| Factor (Weight) | Rental Baseline | Fix & Flip Baseline | BRRRR Baseline | Key Adjustments |
|---|---|---|---|---|
| Return (30%) | Rank+Delta Hybrid based on AR vs all deals | Same formula; penalized if AR ≤ 0 | Same formula; capital recovery can boost AR | Hard Floor = 0 if AR ≤ 0. Return Dominance ≥25% relative forces Clear Winner regardless of Composite. |
| Risk (20%) | Baseline 70; −10–30 for leverage, DSCR; +10–15 for DSCR ≥ 1.25/1.5 | Baseline 40; +10 for 70% Rule pass; −20 fail; adjusted for rehab intensity | Baseline 55; adjusted for 75% Rule, post-refi DSCR, seasoning period | ARV Confidence HIGH +5, LOW −15. HM leverage penalty for Flip >80% LTC. |
| Liquidity (15%) | 70 base; reduced for high leverage (>85% LTV) | 80 base (exit event creates liquidity); reduced for long hold periods | 75 base; +15 if capital left ≤ 0 (infinite return); −10 if capital left > $20K | Reflects ease of converting deal to cash. Flip has natural liquidity event at sale. |
| Time-to-Profit (15%) | Operating Break-Even Month: sooner = higher score | Break-Even = hold period (sale event); typically high TTP score for short holds | Financial Break-Even (includes refi proceeds); varies by seasoning + post-refi CF | Month ≤ 12: +30 pts. Month 13–24: +15. Month 25–36: 0. Month >36: −15. Never reached: −30. |
| Effort (10%) | High: 70 (passive PM model); reduces for active management assumptions | Low: 40 (active project management, rehab oversight, sales coordination) | Moderate: 55 (Phase 1 active rehab + refi process; Phase 3 near-passive) | Effort score is static per strategy in v1; v2 will adjust for management type. |
| Scalability (10%) | High: 75 (equity builds, refinanceable, portfolio-stackable) | Moderate: 60 (profit reinvested, but not equity-stacking like Rental/BRRRR) | Very High: 85 (capital recycling via refi is BRRRR's core scaling mechanism) | BRRRR scores highest because capital recycling enables stack without proportional cash increase. |
Matching the decision tool to your strategy
When this calculator is the right tool
Two rentals in the same or different markets — which delivers better 5-year return? Useful when property A is cheaper but property B has better rent. The calculator normalizes both into comparable metrics.
You have an ARV estimate and rental comps. Should you buy-and-hold (Rental) or rehab-and-refinance (BRRRR)? Compare identifies which strategy unlocks more 5-year value from the same acquisition.
The classic flipper's dilemma. Run Mode A for reinvestment default; toggle Mode C for realistic ROI compression. Pre-tax comparison only — taxes on flip profit are substantially higher than long-term capital gains.
Considering selling a rental and redeploying capital? Compare the current rental's projected 5-year return against new acquisition candidates to determine if capital is better deployed elsewhere.
Pre-vet deals before assignment or loan approval. Low Winner Tier confidence signals buyer hesitation risk. Paired with 70% Rule and 75% Rule for acquisition filters.
Agents and advisors use the calculator to illustrate strategy trade-offs to clients. PDF export provides documentation for investment conversations and professional presentations.
Active investors managing 5–15 deal candidates per quarter use Deal Screening mode to rank-order opportunities. Metrics generated (Total Return, Annualized Return, Composite Score) provide an objective basis for prioritizing capital deployment — supplementing gut feel with normalized numbers.
When two or more investors pool capital, Compare Deals provides a neutral, documented basis for evaluating competing deal candidates each partner brings to the table. The PDF export and Share URL create a reference point for partnership investment committee discussions — reducing subjective disagreement about which deal is objectively better.
Existing rental owner can model: (a) cash-out refi and deploy proceeds into a new deal, or (b) hold and continue current rental. Compare the redeployed BRRRR scenario against the do-nothing Rental scenario. Winner logic identifies whether redeployment creates enough additional return to justify transaction costs and refi complexity.
Normalization methodology and its precedents
The 5-year horizon is industry convention for hold analysis across real estate investment tools. Dual metrics (Total Return + Annualized) align with BiggerPockets and DealCheck conventions for cross-strategy comparison. The reinvestment assumption for Flips matches standard methodology used in comparative real estate analysis (e.g., Roofstock). The Normalization Invariant (±$100 identity check) is unique to RealCalc — it ensures internal calculation consistency and flags invalid deals before Winner logic runs.
Generic calculators always name a winner — this is false precision that can lead to expensive mistakes. RealCalc uses 3-tier confidence (inspired by weather forecasting and medical diagnostic conventions): Clear Winner, Slight Edge, and Too Close to Call. Cluster Detection for 3-deal scenarios is original to RealCalc and addresses the specific edge case where pairwise winners would differ by less than the cluster threshold. This calibrated honesty distinguishes the tool from simpler comparison approaches.
DealCheck offers stronger single-deal depth but weaker multi-strategy comparison across 3 different deal types simultaneously. BiggerPockets provides community-driven benchmarks and education but has no native comparison tool across 3 strategies with calibrated Winner tiering. Mashvisor focuses on market-level analytics and deal discovery but lacks deal-to-deal comparison at the input level. RealCalc Compare Deals is unique in: (a) cross-strategy normalization with equity-basis Terminal Value, (b) hub-screener imports from specialized calculators, and (c) Winner Tiering with Cluster Detection and Return Dominance Rule.
Most real estate calculators use a single return metric without distinguishing time-value methods. Compare Deals uses CAGR (Compound Annual Growth Rate) for Rental, BRRRR, and Flip reinvestment scenarios — because these assume ongoing capital deployment over the full 5-year period. For single-flip mode, the calculator switches to IRR (Internal Rate of Return) via Newton-Raphson iteration — because a single flip generates a lump-sum return at a specific exit month, and IRR correctly accounts for the time value of intermediate cash flows. When a comparison contains both IRR-based and CAGR-based deals, a "Mixed Annualization Methods" advisory note is displayed — not a limitation, but a reminder that the metrics are technically different despite being expressed in the same units (% per year).
No other publicly available real estate comparison tool implements a normalization invariant check. For every deal, the calculator verifies: |Total Return − (CumCashFlow + Terminal − Cash Invested)| ≤ $100. This ensures internal mathematical consistency — that the headline metrics match the month-by-month simulation. If the invariant fails (gap > $100), the deal is flagged INVALID and no Winner is declared. This prevents phantom Winners from calculation bugs, mismatched inputs, or edge cases in the normalization engine. A tolerance of $100 (not $0) accommodates rounding in 60-month cumulative calculations. Deals failing this check should be reviewed for input errors before any capital decision.
What Compare Deals cannot tell you
All figures shown are pre-tax. Tax treatment differs materially between strategies: flip profits are taxed as ordinary income or short-term capital gains; rentals benefit from depreciation deductions and long-term capital gains rates. Post-tax Winner may differ significantly from pre-tax Winner — especially in Flip vs Rental comparisons.
Consult a real estate CPA before committing capital. Tax treatment can reverse the Winner in some scenarios.
Default Flip mode (Mode A) assumes 100% reinvestment into identical flips over 5 years. This is MATHEMATICALLY optimistic and real-world rarely achievable at scale — deal flow is uncertain, ROI compresses with competition, each new flip carries independent execution risk. For a more defensible projection, toggle Mode C (ROI degradation, opt-in) which applies 5–10% ROI compression per cycle (default 7%). Single-flip mode (IRR-based) is available for investors who want per-deal analysis only. Extreme Flip Guard flags projections > 80% Annualized Return AND auto-downgrades Winner tier one level. Treat Flip Total Return with more skepticism than Rental or BRRRR Total Return.
All comparisons use 60 months. This prevents apples-to-oranges across different hold strategies. Some strategies optimize for shorter (house-hack, short-term rental) or longer (generational wealth) holds — this tool does not model those. Horizon override is planned for v2.
Future appreciation cannot be predicted. User-entered assumptions drive 5-year projections — small changes (1–2pp) meaningfully alter results. Conservative / Base / Optimistic scenario stress-tests help identify sensitivity. Global assumptions (not per-deal) prevent biased comparisons by default.
The 30/20/15/15/10/10 factor weights embed editorial judgment — a different expert might weight Risk higher or Return lower. Different weight schemes can produce different Winners. Weight override is planned for v2. The Return Dominance Rule prevents Composite from overturning economically decisive Winners, but within the 15% band, the weights have significant influence.
Avoid these five errors
In v1, the calculator enforces GLOBAL Appreciation and Rent Growth by default. If advanced mode is enabled and you override per-deal assumptions, do so only with market justification (e.g., Austin 5% vs Cleveland 2%) — not preference for one deal. Mismatched assumptions invalidate the comparison by giving one deal an artificial advantage.
"Too Close to Call" means "don't use financial analysis to decide." Users who override this tier and choose the marginally higher-performing deal often regret it when assumptions shift. The tier is the confidence signal — heed it rather than treating all outputs as equally actionable.
Mode A assumes 100% reinvestment into identical flips over 5 years — this is an IDEALIZED projection, not a realistic forecast. Real flippers rarely sustain the same ROI across 8+ deals in 5 years: deal flow dries up, ROI compresses with competition, rehab overruns compound, and market softening breaks the chain. Ask yourself: "Can I realistically close 8 flips in 5 years at the same ROI?" If not, toggle Mode C (ROI compression, default 7% per cycle). Extreme Flip Guard also auto-flags projections > 80% annualized.
A Cleveland Rental and an Austin BRRRR operate in different economic regimes with different appreciation and rent growth trajectories. Relative comparison is valid; but absolute expectations should still be market-adjusted. Use per-deal appreciation and rent growth overrides in advanced mode when modeling different markets.
Compare is a decision tool, not due-diligence. Validate each deal first in single-deal calculators: Does Cap Rate meet market standards? Is DSCR above 1.00? Does the Flip pass the 70% Rule? Is the ARV realistic? Bring only finalized, individually validated deals to Compare for ranking.
The Composite Score is a qualitative tie-breaker within the 15% Annualized Return band — it is not the primary ranking metric. A deal with Composite Score 85 and Annualized Return 9% does NOT beat a deal with Composite Score 72 and Annualized Return 15% — the Return Dominance Rule prevents Composite from overturning a decisive Annualized Return lead (≥25% relative). Investors sometimes anchor to Composite Score because it feels like a comprehensive "grade" — but Return, Risk, Liquidity, Effort, and Scalability are editorial weights, not objective measurements. The Annualized Return is the objective time-normalized rate; the Composite Score provides context.
The calculator verifies each deal passes a normalization invariant: |Total Return − (CumCashFlow + Terminal − Cash Invested)| ≤ $100. If this check fails, the deal is flagged INVALID and no Winner is declared. This invariant is a mathematical consistency check — if it fails, there is a logic error in the inputs (e.g., mismatched cash-flow and terminal equity calculation assumptions). INVALID deals should prompt you to re-verify inputs, especially ARV, loan terms, and cash invested. Do not proceed to capital deployment on a deal that triggers an INVALID flag — the model's internal consistency has broken down.
Run each check before using Compare Deals to rank finalized candidates
Common questions about comparing real estate deals
At-a-glance comparison of Rental, Fix and Flip, and BRRRR economics
| Dimension | Rental | Fix & Flip | BRRRR |
|---|---|---|---|
| Primary Return Driver | Appreciation + Cash Flow | Sale Profit × Reinvestment Cycles | ARV Uplift + Post-Refi Cash Flow |
| Capital Event | None during hold (equity locked) | Sale at hold period end | Refinance at seasoning (capital extraction) |
| Cash Flow Pattern | Monthly (positive or negative) | Negative during hold; lump-sum at exit | Negative Phase 1; positive Phase 3 (post-refi) |
| Risk Profile | LOW–MODERATE (Baseline 70) | MODERATE–HIGH (Baseline 40) | MODERATE (Baseline 55) |
| Effort Level | Low (passive PM model) | High (active rehab + sale management) | Moderate (active Phase 1; passive Phase 3) |
| Scalability | High (refinanceable portfolio) | Moderate (profit reinvestment) | Very High (capital recycling) |
| Key Validation Rule | DSCR ≥ 1.00; Cap Rate ≥ 5% | 70% Rule: Price ≤ ARV×0.70 − Rehab | 75% Rule: (Price + Rehab) ≤ ARV×0.75 |
| Annualized Method | 5Y CAGR | 5Y CAGR (reinvest) or IRR (single flip) | 5Y CAGR |
| Tax Treatment | Long-term cap gains + depreciation deduction (pre-tax not shown) | Ordinary income (short-term) or LTCG (hold >1yr) — pre-tax not shown | Long-term cap gains + depreciation; refi not a taxable event — pre-tax not shown |
| 2026 Rate Sensitivity | High: 7–7.5% rates compress cash flow | High: HM rates 11–13% increase hold cost drag | High: 7–8% refi rates reduce post-refi CF |
