Long-Term Rental Property Analysis — What This Calculator Does

A lifetime wealth projection tool for 1–30 year hold strategies

The Rental Property ROI Calculator helps you project how much total wealth a rental property will build over 1 to 30 years — and understand whether the annualized return is worth your time and capital. Unlike a standard real estate roi calculator that shows only Year 1 metrics, this investment property roi calculator models the full hold period to deliver both Total ROI % and Annualized Return (IRR). Whether you're evaluating a new acquisition or stress-testing an existing property's long term rental roi, this tool provides the multi-year perspective US buy-and-hold investors need in the 2026 market.

At the core of this tool is a 4-component Wealth Waterfall that breaks down Total ROI into: Pre-Tax Cumulative Cash Flow, Principal Paydown, Appreciation, and Estimated Depreciation Benefit — minus Sale Tax at exit (Depreciation Recapture + Capital Gains). This decomposition reveals not just how much a deal returns, but where that return comes from. The calculator supports hold periods from 1 to 30 years with standard analytical checkpoints at 5/10/15/20/25/30, and reports two primary metrics simultaneously: Total ROI % (absolute return over the hold period) and Annualized Return (IRR, time-normalized).

This tool works hand-in-hand with the Rental Property Calculator for Year 1 operating analysis. The recommended workflow: run the Rental Property Calculator first to validate Year 1 cash flow and DSCR, then click "Analyze long-term ROI" to pre-fill this tool and project lifetime wealth. For cross-strategy comparison (Rental vs BRRRR vs Fix and Flip), use the Compare Real Estate Deals tool. This calculator is designed for long-term buy-and-hold investors, retirement portfolio builders, and real estate professionals presenting 10–30 year projections to clients — not short-term flippers.

Tax transparency: All figures combine pre-tax cash flow with estimated depreciation benefit and deducted sale tax (Depreciation Recapture + Capital Gains). Annual income tax on rental profit is NOT modeled. This is partial after-tax, not fully after-tax. Results are projections based on your inputs, not guarantees. Consult a real estate CPA for precise tax planning. Enter your first property above, or import from Rental Property Calculator for instant long-term analysis.

How to Use the Rental Property ROI Calculator

From property inputs to 10-year wealth projection

  1. 1

    Enter acquisition and financing details

    Enter Purchase Price, Down Payment %, Closing Costs %, and any Initial Rehab budget. Then set Loan Rate, Loan Term, and Loan Type (Conventional, DSCR, or Portfolio). These inputs determine your Initial Cash Invested — the denominator of your ROI calculation. Tip: if you've already run this deal through the Rental Property Calculator, click "Analyze long-term ROI" on that page to import all inputs automatically via URL parameters.

  2. 2

    Enter rental income and operating assumptions

    Enter Monthly Rent, Vacancy %, Annual Rent Growth %, and OpEx % of Rent. Rent Growth 3% is the US national average (2–4% typical by market). Vacancy 8% is a conservative default — your market may differ. OpEx 35% accounts for repairs, management, insurance, property taxes, and reserves. Underestimating OpEx is the most common source of optimistic projections.

  3. 3

    Set appreciation and hold period

    Enter Annual Appreciation % — 3% is the US historical average for residential real estate. Hold Period ranges from 1 to 30 years; 10 years is the default for typical long-hold strategy. Warning: hold periods ≤3 years trigger a "short hold warning" because selling costs and sale tax heavily dominate the return at short holds. For Hold = 1 year, a special disclosure appears: sale tax treatment is approximate because actual short-term vs long-term treatment depends on exact holding dates.

  4. 4

    Review tax parameters (Advanced — usually leave defaults)

    Marginal Tax Rate, Land Value %, Selling Cost %, Federal LTCG Rate, and State CG Rate all have sensible defaults for most investors. Depreciation is automatically calculated over 27.5 years on the non-land portion of purchase + rehab. Sale tax uses a SPLIT formula: Depreciation Recapture (25%) on accumulated depreciation + LTCG on remaining gain. This is meaningfully more accurate than simplified "single rate" calculators. For state-specific accuracy, override State CG Rate (e.g., CA 9.3%, TX/FL/NV 0%).

  5. 5

    Interpret Total ROI, Annualized Return, and Wealth Waterfall

    The primary output shows Total ROI % over the hold period AND Annualized Return (IRR). The Wealth Waterfall breakdown shows where total wealth comes from: pre-tax cash flow + principal paydown + appreciation + estimated depreciation benefit, minus sale tax. For most long holds, Appreciation is the largest component (50%+ of Total Wealth) — this is leverage compounding over time. Use the Hold Period Sensitivity tab to see how "when you sell" affects your IRR. All figures combine pre-tax cash flow with estimated depreciation benefit and deducted sale tax. Annual income tax on rental profit is NOT modeled. Consult a real estate CPA for precise tax planning.

Pro Tip: Dual Metrics

Total ROI % shows how much wealth the deal creates; Annualized Return (IRR) shows whether it was worth the time. A 300% Total ROI over 25 years is weaker than 100% over 7 years on an annualized basis. Always judge by BOTH — they answer different questions.

Pro Tip: Waterfall Reading

If Appreciation is the biggest component of Total Wealth, the deal depends heavily on market assumptions. Run the Conservative scenario (−2pp appreciation) to stress-test. If Total ROI drops dramatically, the deal is "market-dependent."

Pro Tip: Hold Period Optimization

Use Hold Period Sensitivity mode to find your optimal exit year. IRR typically peaks at 7–15 years for most rentals — earlier exits lose to selling costs + sale tax; later exits spread returns over more time.

Pro Tip: Year 1 First

Run every deal through the Rental Property Calculator first to validate Year 1 cash flow and DSCR. Only after operating metrics pass should you analyze 10+ year ROI here. A deal that fails Year 1 rarely recovers through appreciation alone.

Choosing the Right Mode

Forward ROI (indigo) — Use when you have a specific property + hold period in mind and want to see projected wealth creation. Output: Wealth Waterfall + Total ROI + IRR + Wealth Break-Even Hold Period.
Hold Period Sensitivity (blue) — Use when you want to see how hold period affects ROI. Output: side-by-side comparison table at 5/10/15/20/25/30 year checkpoints, with "optimal hold" highlighted by highest IRR.
Compare Sell Years (emerald) — Use when you've narrowed to two specific exit years and want detailed side-by-side projection. Output: Total ROI, IRR, Net Proceeds, Remaining Loan, and "Better Annualized Return" winner label. Note: 1031 Exchange and mid-hold refinance are v2 features not supported in v1.

How the Rental Property ROI Calculator Works

6-phase simulation from acquisition to sale — with a worked Austin, TX 2026 example

The Rental Property ROI Calculator runs a 6-phase simulation: (1) Initial Cash Invested, (2) Loan Amortization Schedule, (3) Year-by-Year Cash Flow with rent growth, (4) Terminal Sale with split tax calculation, (5) Wealth Waterfall decomposition, (6) Total ROI and IRR. Unlike single-year calculators, this tool models the full hold period — 1–30 year hold periods — to show how cash flow, principal paydown, appreciation, and tax benefits combine into total wealth creation. Results are projections based on user inputs and 27.5-year residential depreciation, not market-reported data.

╚══════════════════════════════════════════════════════════════════════════╝

Phase 1 — Initial Cash Invested

Down Payment = Purchase × Down Payment %

Closing Costs = Purchase × Closing %

Initial Cash Invested = Down Payment + Closing Costs + Rehab

Phase 2 — Loan Amortization

Monthly Payment = Loan × [Rate/12 × (1+Rate/12)^N] / [(1+Rate/12)^N − 1]

For each month m: Interest_m = Balance × Rate/12; Principal_m = Payment − Interest_m

Sum Principal payments over hold period → Principal Paydown (Wealth Waterfall)

Phase 3 — Year-by-Year Simulation

Gross Rent_Y = Monthly Rent × 12 × (1 + Rent Growth)^(Y-1)

Effective Rent_Y = Gross Rent × (1 − Vacancy %)

NOI_Y = Effective Rent × (1 − OpEx %)

Pre-Tax Cash Flow_Y = NOI − Annual Debt Service

Annual Depreciation = (Purchase + Rehab) × (1 − Land %) / 27.5

Estimated Depreciation Benefit_Y = Depreciation × Marginal Tax Rate

Phase 4 — Terminal Sale + SPLIT Tax (canonical — never simplified)

Property Value_Sale = Purchase × (1 + Appreciation)^Hold

Selling Costs = Sale Value × Selling Cost %

Accumulated Depreciation = Annual Depreciation × Hold Period

Adjusted Basis = Purchase + Rehab − Accumulated Depreciation

Total Gain = (Sale Value − Selling Costs) − Adjusted Basis

// SPLIT Tax — Rule 3 canonical formula (NEVER single combined rate):

Recapture Tax = 25% × min(AccumDepr, max(0, Total Gain))

LTCG Gain = max(0, Total Gain − AccumDepr)

Capital Gains Tax = LTCG Gain × (Federal LTCG + State CG)

Total Sale Tax = Recapture Tax + Capital Gains Tax

// Loss-sale edge case: if Total Gain ≤ 0, all taxes = 0

Phase 5 — Wealth Waterfall (explanatory decomposition)

Total Wealth = Cumulative Cash Flow + Principal Paydown + Appreciation

+ Estimated Depreciation Benefit − Total Sale Tax

Phase 6 — Total ROI + Annualized Return (IRR)

Total ROI % = Total Wealth / Initial Cash Invested × 100

IRR cash flows: CF_0 = −Initial Cash; CF_1..N-1 = Pre-Tax CF per year

CF_N = Year N CF + Net Proceeds at Sale

Solve: NPV = Σ(CF_t / (1+IRR)^t) = 0 via Newton-Raphson (tolerance 0.01%)

If solver fails → CAGR fallback with "(approximated)" label + ⓘ info icon

Worked Example — Austin, TX (2026 10-Year Hold)

Inputs: $300K purchase, 25% down, 2% closing, $0 rehab, 7.5% rate/30yr, $2,200/mo rent, 8% vacancy, 35% OpEx, 3% appreciation, 3% rent growth, 10-year hold, 24% marginal tax, 20% land, 7% selling cost, 15% Fed LTCG, 0% State CG

Phase 1: Initial Cash = $75,000 + $6,000 = $81,000

Phase 2: Loan = $225,000; Monthly P&I ≈ $1,573; Principal paid at Y10 ≈ $35,200

Phase 3: Year 1 NOI ≈ $16,750; Pre-Tax CF Yr1 ≈ −$1,100 (thin due to 7.5% rate); CF grows as rent grows

Phase 4: Sale value at Y10 = $300K × 1.03^10 = $403,175; Selling costs = $28,222; Remaining loan ≈ $189,800

Phase 5 SPLIT Tax: AccumDepr = $240K/27.5 × 10 = $87,273; Adj Basis = $300K−$87,273 = $212,727

Total Gain = ($403,175−$28,222)−$212,727 = $162,226

Recapture = 25% × min($87,273, $162,226) = $21,818; LTCG = 15% × ($162,226−$87,273) = $11,243

Total Sale Tax = $33,061 (vs single-rate at 15% = $24,334 — 36% underestimate)

Phase 6 Waterfall: CF≈$8–12K + PP≈$35K + Appre≈$103K + DepBenefit≈$6.3K − SaleTax≈$33K ≈ Total Wealth $119K–$123K

Total ROI ≈ 147% | IRR ≈ 11.5% | Wealth Break-Even ≈ Year 5

CRITICAL: Combined-Tax Formula Is Forbidden

Any formula applying a single combined rate to Total Gain is incorrect and explicitly rejected. The correct formula ALWAYS separates: Recapture Tax (25% × capped accumulated depreciation) + Capital Gains Tax (LTCG rate × remaining gain). The simplified single-rate approach underestimates tax liability by 20–35% in typical cases.

What Is Rental Property ROI?

Lifetime wealth analysis vs. single-year operating snapshot

Traditional "rental ROI" often means Year 1 Cash-on-Cash return — a single-year snapshot of income against cash invested. Lifetime Rental ROI is fundamentally different: it measures total wealth created over a multi-year hold period (1–30 years, with standard checkpoints at 5/10/15/20/25/30). It includes four wealth drivers — cash flow, principal paydown, appreciation, and depreciation tax benefits — minus sale tax at exit. Most rental properties are weak on Year 1 cash flow but strong on 5-year+ Total ROI because appreciation and leverage compound over time. This calculator implements the full lifetime analysis with proper split tax treatment.

Total ROI alone doesn't tell you where the return came from. Decomposing Total Wealth into 4 components via the Wealth Waterfall reveals the deal's nature: a high Cash Flow component indicates operational efficiency; high Principal Paydown means leverage is working for you; high Appreciation means the deal is market-dependent (run Conservative scenario to stress-test); high Estimated Depreciation Benefit means a high-bracket investor extracts significant tax value. If Appreciation dominates (50%+), the deal is essentially a bet on future property values. If Cash Flow and Principal Paydown dominate, the deal is more resilient to market changes.

Annualized Return (IRR) measures per-year return including all cash flows and final sale, accounting for the time value of money. A 200% Total ROI over 25 years is actually lower IRR than 100% over 7 years. This calculator uses the SPLIT sale tax formula (Depreciation Recapture 25% + LTCG on remaining gain) — more accurate than simplified "single rate" calculators that underestimate tax liability by 20–35%. All outputs use "partial after-tax" framing: pre-tax cash flow + estimated depreciation benefit + sale tax. Annual income tax on rental profit is NOT modeled. Consult a CPA for precise after-tax analysis.

What Your Total ROI and Annualized Return Mean

Interpreting the DUAL primary metrics + Wealth Break-Even

Total ROI answers "how much wealth did the deal create relative to my cash invested?" while Annualized Return (IRR) answers "at what annual rate did I earn that return?" Both matter — they answer different questions and should always be evaluated together.

Total ROI % Tiers — 10-Year Hold

Below 120%Weak — underperforms typical long-hold rentals
120–220%Average — standard long-hold return
Above 220%Strong — above-average appreciation, cash flow, or leverage

For 20-year hold: roughly double; for 5-year hold: roughly half.

Annualized Return (IRR) Tiers

Below 6%Below Market — review assumptions
6–9%Market Rate — comparable to S&P 500
9–13%Good — above-market with leverage + tax benefits
13–18%Strong — high-quality deal with appreciation
Above 18%Exceptional — verify inputs, may be aggressive
NegativeLoss projected — review assumptions

Wealth Break-Even Hold Period — What It Tells You

The Wealth Break-Even Hold Period is the year at which cumulative wealth (including hypothetical sale tax if sold that year) first turns positive. This is different from operational cash-flow break-even.

  • Year 1–3: Deal starts generating value quickly, often driven by appreciation + leverage
  • Year 4–7: Typical for most US rentals with standard assumptions
  • Year 8+: Deal is heavily tax/appreciation-dependent; may not recover early exit
  • "Beyond 30 years": Deal does not pay back total wealth — review inputs, may be genuinely unviable

2026 US Rental Market Context

Post-2022 mortgage rates (7–8%) compress Year 1 cash flow significantly — many 2026 deals show negative or near-zero Year 1 cash-on-cash. Appreciation has normalized to 3–4% from the 2020–2022 surge. Rent growth moderated to 2–4% nationally. Many 2026 deals show weak Year 1 CoC (1–4%) but strong 10-year IRR (10–13%) because appreciation and principal paydown compensate for thin early cash flow. This is exactly why lifetime ROI analysis matters more than ever in 2026 — Year 1 metrics alone can make good deals look bad.

Rental Property ROI Benchmarks for 2026

What total returns and IRR look like across hold periods

These ranges are illustrative patterns based on commonly-used assumption levels, not measured statistical datasets. Individual results depend heavily on your specific location, leverage, appreciation, and execution quality.

Typical Wealth Waterfall Composition (10-Year Hold, 25% Down)

  • Appreciation50–65% of Total Wealth
  • Principal Paydown20–30% of Total Wealth
  • Cumulative Cash Flow5–15% of Total Wealth
  • Estimated Depreciation Benefit3–8% of Total Wealth
  • MINUS Sale Tax20–25% reduction from positive components

Appreciation >70% means market-dependent. Cash Flow >20% means unusually strong operating economics.

Benchmarks disclaimer: These ranges reflect illustrative outcomes at commonly-used assumption levels (3% appreciation, 3% rent growth, 25% down, 30-year amortization). They are NOT measured statistical datasets, NOT market research, NOT predictions for any specific deal. Actual results depend on your specific inputs, local market, financing, execution quality, and tax situation. The calculator's output on YOUR inputs always takes precedence over these aggregate expectations.

How to Use Rental Property ROI by Investor Type

Matching the analysis to your long-term goals

First-Time Investor

Start with 10-year hold at default assumptions (3% appreciation, 3% rent growth) and compare Forward ROI against IRR Tiers — aim for 9%+ IRR as a minimum threshold. Use the Conservative scenario to stress-test before committing capital. Validate Year 1 operations in the Rental Property Calculator first — deals that fail Year 1 rarely recover through appreciation alone.

Scaling Investor (3–10 Properties)

Use Hold Period Sensitivity mode to identify the optimal exit year per property. Prioritize properties with high Principal Paydown component (leverage working in your favor). Watch for Appreciation-dominated deals (>60%) — market dependency adds portfolio-level risk. For 1031 Exchange planning to defer taxes on sale proceeds, consult a CPA (1031 Exchange is a v2 feature not modeled in v1).

Retirement Portfolio Builder

Use 20–30 year hold periods to see cumulative wealth at your planned retirement year — appreciation and principal paydown compound dramatically at long holds. Focus on the Wealth Break-Even Hold Period to understand when the deal turns wealth-positive. Use Compare Sell Years mode to test "sell at retirement" vs. "sell earlier" scenarios. Estimated Depreciation Benefit compounds significantly over 20+ year holds.

Real Estate Agent / Advisor

Present the Wealth Waterfall visualization to clients as a clear breakdown of return sources — this builds trust and differentiates your presentations. Use Hold Period Sensitivity for "when should I sell?" conversations. IRR tiers provide a benchmarking framework for deal quality comparison. Always caveat: projections are not guarantees; recommend a real estate CPA for tax specifics before any major decision.

Existing Portfolio Evaluator

Run current properties at their actual current state — use today's property value as "purchase price" and the remaining hold period as the hold years. Compare "hold another 10 years" ROI against "sell now + redeploy" alternative. Consider whether the Appreciation component still has runway (late-cycle markets may have limited future appreciation). Use Compare Real Estate Deals to test "sell + buy BRRRR" or other redeployment scenarios.

Common Use Cases

When this calculator is the right tool

1

Pre-purchase long-term ROI validation

Before committing capital, validate that 10-year projected IRR meets your threshold (typically 9%+). Run Conservative scenario to confirm the deal survives reasonable market softening.

2

Portfolio hold-vs-sell decision

For an existing rental, run Forward ROI with remaining hold period to see projected wealth creation from today forward. Compare against "sell now + redeploy" via Compare Real Estate Deals.

3

Retirement planning with rental income

Model 20–30 year holds to see cumulative wealth at your planned retirement year. Shows how cash flow + appreciation + principal paydown combine into retirement portfolio value.

4

Client presentations (agents, advisors)

Use the Wealth Waterfall visualization to explain return drivers clearly to clients. PDF export provides documentation for investment conversations and lender presentations.

5

Estimated Depreciation Benefit planning

Quick estimate of annual depreciation tax benefit for planning purposes. Note: v1 assumes full deductibility — consult a CPA for passive activity loss implications at higher incomes.

6

Optimal hold period identification

Use Hold Period Sensitivity mode to find the hold period that maximizes IRR. Typically peaks at 7–15 years depending on leverage and appreciation assumptions.

How This Calculator Aligns with Industry Conventions

Methodology standards and peer tool positioning

Lifetime ROI Methodology

1–30 year hold periods with standard analytical checkpoints at 5/10/15/20/25/30 match institutional real estate analysis horizons. The 4-component wealth decomposition (cash flow + principal + appreciation + depreciation) aligns with CCIM and institutional REIT frameworks. 27.5-year residential depreciation per IRS §168 is standard. Split sale tax (Recapture 25% + LTCG per IRC §1250) is the correct treatment — not a simplified estimate. IRR as the annualization metric matches private equity and REIT reporting standards.

Tax Treatment Conventions

Pre-tax cash flow display matches BiggerPockets and DealCheck industry convention. Estimated Depreciation Benefit as a separate line (not blended into cash flow) prevents confusion. The split sale tax calculation (Recapture + LTCG) is the correct IRS treatment; most consumer calculators simplify to a single rate. "Partial after-tax" framing honestly discloses what IS and ISN'T modeled. Annual income tax on rental profit is intentionally not modeled — it's too personal-tax-situation-specific for a universal calculator.

How This Differs from BiggerPockets / DealCheck / SparkRental

BiggerPockets has strong single-year rental analysis but weaker multi-year lifetime wealth decomposition. DealCheck offers multi-year projections but uses a combined sale tax rate that underestimates liability. SparkRental has strong educational content but less detailed lifetime modeling. RealCalc Rental Property ROI is unique in: (a) 4-component Wealth Waterfall with visual breakdown, (b) split Recapture + LTCG tax formula (correct, not simplified), (c) 3 modes including Hold Period Sensitivity, and (d) cross-calculator invariant with Rental Property Calculator for Year 1 validation.

Limitations of This Calculator

What Rental Property ROI cannot tell you

Total Wealth Created =

Pre-Tax Cash Flow

+ Principal Paydown

+ Appreciation

+ Estimated Depreciation Benefit

− Sale Tax (Recapture + LTCG)

This is a PARTIAL-TAX model:

✓ Includes: estimated depreciation benefit + sale tax (Recapture + LTCG)

✗ Excludes: annual income tax on rental profit, NIIT (3.8% for high earners),

passive activity loss limits, state income tax variations,

alternative minimum tax

1

Partial after-tax framing, not fully after-tax

Pre-tax cash flow is displayed with estimated depreciation benefit added and sale tax deducted. Annual INCOME tax on rental profit is NOT modeled. Passive activity loss limits (IRC §469), at-risk rules, NIIT (3.8% for high earners), and state income tax variations are all NOT modeled. See the Canonical Partial-Tax Model above. Consult a real estate CPA for precise after-tax analysis.

2

Estimated Depreciation Benefit is estimated, not guaranteed

The label "Estimated Depreciation Benefit" is intentional. The linear formula (Annual Depreciation × Marginal Tax Rate × Years) assumes full deductibility each year, which requires the property to be cash-flow positive, the investor to qualify under passive activity rules (IRC §469), and at-risk basis to be sufficient. Passive Activity Loss limits can cap deductibility. Consult a CPA for precise tax impact.

3

Sale tax simplified (still split, but approximate)

Uses Federal Depreciation Recapture (25%) + Federal LTCG + State CG, but does NOT model: NIIT 3.8% surtax for high earners, Alternative Minimum Tax, short-term capital gains on sub-1-year holds, or capital loss carryforward from other investments. Year 1 sale tax is especially approximate. More accurate than single-rate calculators, but not a tax preparation tool.

4

Appreciation and rent growth are assumptions

Future real estate values cannot be predicted. Small changes to the appreciation assumption produce large changes in Total ROI at long hold periods (especially 15+ years). The Conservative scenario (−2pp appreciation) stress-tests this. Results are projections based on YOUR inputs, not market forecasts.

5

Does not model 1031 Exchange, refinance, or portfolio rollover

v1 scope is limited to single-property hold-and-sell scenarios. 1031 Exchange (tax deferral via replacement property) requires replacement-property assumptions — this is a v2 roadmap feature. Mid-hold cash-out refinance also requires new loan terms — v2 feature. For multi-property portfolio analysis or 1031 planning, consult a financial advisor and qualified intermediary.

6

Not a substitute for professional advice

This is an educational and deal-screening tool. Before committing capital, consult: a real estate CPA for tax specifics, an attorney for entity structure, a lender for actual financing terms, and a real estate advisor for market specifics. This calculator is not investment advice and is not a substitute for professional tax, legal, or financial guidance.

When Not to Use This Calculator

  • Year 1 operational analysis: use Rental Property Calculator for monthly cash flow, DSCR, Year 1 CoC
  • Short-term flips (<1 year): use Fix and Flip Calculator
  • BRRRR strategy: use BRRRR Calculator for refi-focused analysis
  • Cross-strategy comparison: use Compare Real Estate Deals
  • Tax preparation: consult a CPA — this calculator is not a tax prep tool
  • 1031 Exchange planning: v2 feature; consult CPA + qualified intermediary
  • Commercial or multifamily 5+ units: calculator assumes residential 1–4 unit

Common Mistakes When Analyzing Rental ROI

Avoid these five errors

Comparing Total ROI across different hold periods

200% ROI over 20 years is weaker than 100% over 7 years on an annualized basis. Always compare IRR (annualized) when evaluating deals across different hold periods — not Total ROI %, which is not time-normalized.

Treating Estimated Depreciation Benefit as guaranteed savings

Passive activity loss limits, at-risk rules, and your personal tax situation can significantly reduce actual benefit. The linear formula assumes full deductibility each year, which many investors at higher incomes cannot achieve. Consult a CPA for precise tax planning.

Ignoring appreciation dependence in the Wealth Waterfall

If Appreciation is >60% of Total Wealth, the deal is essentially a bet on future property values — not a cash-flow-driven investment. Run the Conservative scenario (−2pp appreciation) to see how fragile the projection is. If Total ROI drops dramatically, the deal requires market tailwinds.

Overlooking sale tax impact at exit

Depreciation Recapture (25%) + LTCG can eat 20–30% of gross sale gains. Tax-free exits via 1031 Exchange are possible but require replacement property planning — not modeled in v1. Factor in the full split tax cost before comparing deals to alternative investments.

Using lifetime ROI without validating Year 1 operations first

A property that fails Year 1 DSCR or shows a deeply negative cash-on-cash rarely recovers through appreciation alone. Always run the Rental Property Calculator first; bring only operationally viable deals to lifetime analysis.
