ARV is an estimate, not a calculation
This tool approximates After Repair Value using comparable sales methodology. Results carry inherent uncertainty and are for investor screening only. Not a substitute for licensed appraisal. Lenders will not accept this output for loan underwriting.
ARV (After Repair Value) is the projected market value of a property after renovation is complete, expressed in current market dollars. It is the single most important input in flip and BRRRR deal analysis — a $10K ARV miss can eliminate entire projected profit on a thin-margin flip. Unlike calculations that produce precise outputs (cap rate, mortgage payment, NOI), ARV is an estimate derived from comparable sales data with inherent uncertainty. Professional appraisers, real estate agents, and experienced investors all approach ARV the same way: find similar recently-sold properties, adjust for differences, and estimate the subject's value in that context.
This calculator uses a Hybrid Comparable Sales + Adjustments methodology. The weighted average $/sqft is computed across 3–5 recent comparable sales, weighted by recency and proximity to the subject. Adjustments are applied for bedroom/bathroom/garage/year-built/lot-size differences using industry-standard rules of thumb ($5K per bedroom, $10K per full bath, $5K per half bath, $10K per garage space). A condition multiplier then reflects the subject's post-rehab state relative to the comp baseline.
Every ARV estimate carries inherent uncertainty — two appraisers given the same comps might produce ARVs that differ by 5–10%. This tool expresses that honestly via the Confidence Range (±$). Tight comp data — similar properties, recent sales, close proximity — produces a narrow range; scattered or old data produces a wider range. Professional investors use the lower bound of the Confidence Range when making offers, not the single-point estimate.
Fix and Flip investors use this tool to calculate Max Offer via the 70% Rule. BRRRR investors use it to project refi ARV and capital recovery. Wholesalers use it to justify assignment fees to end buyers with real comp-backed data. Real estate agents advising investor clients can run a quick ARV estimate in under 5 minutes.
How the calculator estimates after-repair value — with a worked Charlotte, NC example for 2026
Important: ARV is an ESTIMATE, not a calculation.
The formula below is a structured methodology based on appraiser practice, but the output has inherent uncertainty. Two different sets of valid comps will produce different ARV estimates for the same property. The Confidence Range honestly reflects this. For final lending or purchase decisions, always verify with a licensed appraiser or BPO. This calculator is a SCREENING TOOL.
Subject: 3BR/2BA SFR, 1,800 sqft, 1985 build, post-rehab Good condition. 4 comps, all under 120 days, within 0.8 miles.
What each field means and where to find the numbers.
| Field | What it means | Where to find it |
|---|---|---|
| Subject Sqft | Heated/cooled square footage | Listing, appraisal, assessor |
| Subject Bedrooms | Number of bedrooms | Property listing |
| Subject Bathrooms | Full + half baths (2.5 = 2 full + 1 half) | Property listing |
| Subject Condition | Post-rehab condition (Good for move-in ready) | Projected after rehab |
| Comp Sale Price | Actual recorded sale price | MLS, Redfin, Zillow sold |
| Comp Sale Date | Date of closing | Same as above |
| Comp Sqft | Heated/cooled square footage | Same as above |
| Comp Distance | Miles from subject property | Map tool or manual estimate |
| Rehab Budget | Projected renovation cost (triggers 70% Rule) | Contractor bids |
| Output | What it means | Primary use |
|---|---|---|
| Estimated ARV | Projected post-renovation market value | Headline deal screening number |
| Confidence Range | ±$ envelope based on comp spread + score | Realistic offer range |
| Confidence Tier | HIGH/MEDIUM/LOW (estimate reliability) | Know whether to trust the estimate |
| Weighted Avg $/sqft | Comp-derived PPSF used to compute ARV | Sanity check vs local market |
| 70% Rule Max Offer | (ARV × 0.70) − Rehab Budget | Fix and Flip acquisition ceiling |
| 75% Rule All-In Target | ARV × 0.75 | BRRRR capital recovery target |
ARV Confidence Tiers show how reliable your estimate is — not deal quality.
4–5 recent comps, tight PPSF spread, similar properties, close proximity, all under 180 days old.
Reliable for screening and initial offer development. Proceed with deal analysis using this ARV, but verify with BPO before formal offer or lender submission.
3 comps OR mixed recency, moderate PPSF spread (CV 15–30%), 0–1 outliers flagged.
Usable for initial screening but less reliable. Use the Confidence Range — not the point estimate — when considering offers. Widen your margin of safety.
Fewer than 3 comps, wide PPSF spread (>30%), multiple outliers, or subject sqft mismatch.
Estimate has too much uncertainty. Do not use this ARV for offer construction. Find more comps (target 4–5 recent + similar) or order a professional appraisal.
Post-pandemic markets have more regional variance. Hot markets (Austin, Boise, Phoenix) saw ARV decline 5–15% from 2022 peaks while cooling markets stabilized. Comps from 6+ months ago in volatile markets may overstate or understate current ARV by 3–8%. Practical implication: use recent comps (under 90 days preferred, under 180 days maximum), trust Confidence Range over point estimate, and verify with BPO in volatile markets.
Typical 2026 ARV $/sqft ranges across property types and major US markets. Use as sanity check — if your calculated ARV implies $/sqft outside these ranges, verify your comps.
| Property Type | Low Market $/sqft | Mid Market $/sqft | High Market $/sqft |
|---|---|---|---|
| SFR (starter) | $85–$120 | $120–$180 | $180–$280 |
| SFR (move-up) | $110–$150 | $150–$220 | $220–$350 |
| Small Multi (2–4) | $95–$130 | $130–$190 | $190–$300 |
| Condo | $130–$180 | $180–$260 | $260–$420 |
| Townhouse | $100–$140 | $140–$210 | $210–$320 |
Factor 1: Land values are 40–60% of total value in coastal metros vs 15–25% elsewhere — making $/sqft a less reliable standalone metric; lot size premium is significant. Factor 2: permit-heavy renovations add $20–$40/sqft premium to quality rehabs, but also create 3–6 month timing delays that increase holding costs. ARV comps in California require extra care: verify permit history, confirm condition accurately, and prioritize comps within the same micro-neighborhood. Hard money lending in CA is active — $400–$700 appraisal costs are standard.
Factor 1: Dallas and Austin metros have 2–3% annual population growth supporting ARV stability and sustained investor demand. Factor 2: abundant new construction creates pricing competition — existing-home ARVs must stay competitive with new-build pricing per sqft in same zip code. Texas has no state income tax, making it attractive for flip profit; however, property tax rates (2–2.5%) are among the highest nationally, which affects holding cost calculations. ARV methodology works reliably in Texas due to active MLS with accessible sold data.
Factor 1: Population inflow from Northeast and Midwest supports strong buyer demand and relatively stable ARV. Factor 2: hurricane insurance has tripled in many coastal markets since 2020, now factored directly into buyer offers — homes in flood zones or pre-2000 construction without wind mitigation see $20–$40/sqft ARV discount vs non-flood comparable. Miami is a separate premium market with international buyer influence ($300–$600/sqft in many areas).
Factor 1: NY has the widest intra-state ARV variance in the US — NYC metro $/sqft is 3–4x upstate levels. Brooklyn SFR $500–$800 vs Buffalo $80–$140 per sqft. Comps must be hyper-local in NYC metro. Factor 2: permit fees and compliance costs are 3–5% of project value in NYC metro, adding significant ARV premium to fully-permitted renovations vs unpermitted work.
Factor 1: Phoenix metro experienced significant ARV correction in 2022–2023 (8–15% from peak), followed by stabilization in 2024–2025 and moderate recovery. Use comps from 2025–2026 only — pre-correction comps will significantly overstate current ARV. Factor 2: Emerging wildfire risk and extreme heat insurance premiums are starting to factor into buyer purchasing decisions. Scottsdale luxury market operates at $400–$800+/sqft — treat as separate comp pool.
Factor 1: Atlanta metro has reliable 3–4% annual ARV growth, steady buyer demand from in-migration, and a large investor-active market with frequent MLS comp data. Atlanta is one of the top 5 US markets for Fix and Flip volume nationally — reliable comp data availability is excellent. Factor 2: Non-union construction labor and available contractor capacity keep rehab costs 10–15% below coastal markets.
Factor 1: Entry $/sqft of $85–$120 in many Cleveland and Akron submarkets enables smaller investors to enter with lower capital requirements — $150K–$250K total project costs common. Columbus is the growth engine of Ohio ($120–$180/sqft) with 2–3% annual ARV appreciation. Factor 2: ARV growth has been flat-to-negative in several Rust Belt submarkets — requiring careful comp selection from the same active submarket, not the larger metro.
Factor 1: Philadelphia metro $200–$320/sqft vs Pittsburgh $120–$180/sqft — nearly 2x difference within the same state. Always select comps within the relevant metro, not statewide. Factor 2: PA housing stock is predominantly pre-1960 — renovated older properties with period-appropriate finishes command 5–15% ARV premium in Philadelphia neighborhoods like Fishtown, East Kensington, and Manayunk.
How the ARV Calculator supports different real estate investment strategies
Fix and Flip investors use ARV Calculator as the SCREENING TOOL before committing to a deal. Enter 3–5 recent comps and your projected Rehab Budget — the calculator immediately shows Estimated ARV AND 70% Rule Max Offer, the maximum purchase price that supports healthy flip margins.
Practical workflow: screen 5–10 potential deals per week with ARV Calculator, shortlist those that pass the 70% Rule with HIGH Confidence, then analyze shortlist deals in detail with the Fix and Flip Calculator.
BRRRR investors need ARV to project refi proceeds and Capital Left. Enter comps for the post-rehab property state, then check the 75% Rule All-In Target. Your total project cost must stay at or below ARV × 0.75 for full capital recovery at standard 75% LTV refi.
Pair with the BRRRR Calculator for full Phase 1 + refi + Phase 3 rental modeling. Important: lender refi appraisal may come in 3–7% below your ARV estimate — model Conservative scenarios.
Wholesalers use ARV Calculator to justify assignment fees to end-buyer investors. Present a credible ARV with HIGH Confidence tier backed by 4–5 recent comps. Run the calculator WITH your end-buyer's expected rehab budget to show THEM the 70% Rule Max Offer — if your contract + assignment fee is at or below the 70% Rule Max Offer, the deal sells itself.
Agents advising investor clients use ARV Calculator to provide data-driven ARV estimates during deal analysis calls. Pull 3–5 recent comps from MLS, enter into the calculator, and show the client Estimated ARV + Confidence Range + 70% Rule Max Offer in a single screen. Export ARV analysis as PDF to include in deal packages.
Six concrete ways investors use ARV Calculator
Quickly screen 5–10 potential deals per week before committing analysis time. Enter 3–5 comps for each deal candidate, review the 70% Rule Max Offer and Confidence Tier, then decide which deals warrant detailed analysis. Deals passing the 70% Rule with HIGH Confidence become your shortlist.
Calculated ARV plus entered Rehab Budget immediately produces 70% Rule Max Offer: (ARV × 0.70) − Rehab Budget. This is the maximum you can pay for the property while maintaining a 30% buffer for profit, financing costs, and execution risk. Deals at or below this ceiling have built-in flip viability.
BRRRR investors check the 75% Rule All-In Target: ARV × 0.75. This is the maximum total project cost (purchase + rehab + holding + financing) to achieve full capital recovery at a standard 75% LTV refinance. Keep your all-in costs at or below this target. For precise BRRRR modeling, pair with the BRRRR Calculator.
Wholesalers use HIGH Confidence ARV backed by 4–5 recent comps to justify assignment fees to end-buyer investors. Present the Comp Comparison Table, Estimated ARV, and 70% Rule Max Offer — then show that your contract price + assignment fee still falls at or below the 70% Rule ceiling.
Before relying on any ARV estimate, audit your comp quality in the Comp Comparison Table. Watch for: outlier flags (>25% PPSF deviation from median), stale dates (>180 days), significant sqft mismatch with subject (>30%), and low distance quality (>1 mile). The Confidence Score shows exactly which factor is limiting reliability.
For syndicated or partnered flip/BRRRR deals, export ARV + Confidence Range + 70%/75% Rule analysis as PDF directly from the calculator. Include in partner pitches, private lender packages, or HML pre-approval requests as supporting deal data. Always include the Confidence Tier disclosure.

How comparable sales methodology fits into professional appraisal and investor practice.
ARV Calculator is a powerful screening tool, but it has real methodology limits you should understand before making decisions.
This calculator is a SCREENING TOOL, not a substitute for licensed appraisal or Broker Price Opinion (BPO). Lenders will NOT accept this ARV for loan underwriting. For final purchase or lending decisions, always verify with a licensed appraiser ($400–$700) or order a BPO ($75–$150) from a local agent.
The ARV estimate is only as good as the comparable sales you enter. Common data quality issues: incorrect sqft (listing sqft vs finished sqft), non-arms-length sales (foreclosures, estate sales, intra-family transfers), unusual property conditions not reflected in price, or stale comps overstating values in declining markets. Always cross-check comps against MLS, county assessor records, or a local agent contact.
Adjustment rates ($5K per bedroom, $10K per full bath, etc.) are industry rules of thumb derived from general appraiser practice — they are NOT market-derived statistics calibrated to your specific submarket. In high-cost coastal markets, bedroom adjustments can range $15K–$30K. In lower-cost Midwest markets, these same adjustments may be 30–50% of the default values. Advanced mode allows overriding all adjustment rates.
ARV reflects current market conditions at the time you enter your comps — it does NOT model future appreciation, market downturns, or macroeconomic shifts. ARV estimates using comps from today will be stale in 3–6 months. For deals with extended renovation timelines or markets with elevated volatility, re-estimate ARV with fresh comps before making final offer or closing decisions.
The 5 most common investor mistakes when estimating ARV — and how to avoid them.
2026 markets shift faster than pre-2020 eras. A 9-month-old comp from a 2025 hot market may overstate current ARV by 5–8% after the market cooled. The calculator applies recency weighting (comps over 180 days receive 0.5× weight) but very old comps should be viewed skeptically regardless of their weight. Always prefer comps under 90 days.
Investors commonly set Subject Condition to "Excellent" assuming their rehab will produce a premium result. In reality, most rehabs produce "Good" condition (fully renovated, move-in ready), not "Excellent" (recently renovated with premium finishes throughout). Setting Excellent applies a ×1.10 multiplier — overstating ARV by approximately 5% compared to a realistic "Good" setting. Default to "Good" unless you have a detailed scope of work that genuinely justifies Excellent.
The calculator flags comps with PPSF >25% from median as potential outliers. Investors sometimes dismiss these warnings because the flagged comp happens to support a higher ARV — this is confirmation bias, not analysis. Before ignoring an outlier flag: check the sqft in county assessor records, confirm the sale was arms-length, and verify the sale condition was comparable.
The ARV estimate shows a single dollar figure, but the Confidence Range is the more honest signal. Professional investors systematically make offers based on the lower bound of the Confidence Range, not the point estimate, to build in a margin of safety against lender appraisal variance (which typically comes in 3–5% conservative vs investor ARV estimates).
This calculator is a SCREENING tool — it cannot substitute for a licensed appraisal for any purpose that requires professional liability and lender acceptance. Lenders (banks, hard money lenders, private lenders) require appraisals from their approved Appraisal Management Company (AMC) panel. Always budget $400–$700 for a licensed appraisal in your acquisition costs for any deal requiring financing.
In real estate investing, ARV is the single most consequential input in your deal analysis. Here is why getting it right (or wrong) matters so much in 2026:
A $15K ARV overestimate on a $280K expected ARV flip (5.4% miss) reduces your 70% Rule Max Offer by $10,500 — often eliminating your entire target profit margin on a $20–$30K thin-margin flip.
A $20K ARV overestimate on a $300K BRRRR deal means your actual 75% LTV refi proceeds are $15,000 lower than projected — a common BRRRR failure mode.
A 10% ARV overestimate on a $350K ARV deal can make an otherwise-marginal deal look attractive to end buyers — until their due diligence reveals the real ARV and they back out.
Three comps work for a quick estimate but widen the Confidence Range by 3–5%. Adding a 4th or 5th comp that corroborates the weighted average is the single highest-ROI improvement to your ARV accuracy.
A 30-day-old comp from 0.8 miles away typically outweighs a 6-month-old comp from 0.3 miles. 2026 markets shift faster than 2019 — stale comps overestimate current ARV.
If the calculator flags a comp as >25% PPSF deviation from median, review it — wrong sqft data, unusual condition, or atypical market timing could distort your ARV. Verify the data or manually exclude.
Always use the Confidence Range when making offers. Professional investors make offers based on the lower bound to build in margin against lender conservative appraisals.
The calculator uses the following appraiser-standard adjustment values as defaults. Use Advanced mode to override for your specific market.
| Adjustment Type | Default Rate | Notes |
|---|---|---|
| Bedroom difference | ±$5,000 per bedroom | Varies by market — can be $2K–$15K. |
| Full bathroom difference | ±$10,000 per full bath | Industry standard. In luxury markets can reach $15K–$25K per bath. |
| Half bathroom difference | ±$5,000 per half bath | Standard 50% of full bath value adjustment. |
| Garage spaces | ±$10,000 per space | Can be $5K–$20K per space depending on market. |
| Year built difference | ±$500 per year | Applies only when both subject and comp year-built are entered. |
| Lot size difference | ±$5 per sqft (opt-in) | DISABLED by default. Enable in Advanced mode. |
| Condition multiplier | ×0.85 to ×1.10 | Poor=×0.85, Needs-Rehab=×0.93, Average=×1.00, Good=×1.05, Excellent=×1.10. |
Important: These are industry-standard rules of thumb, not market-derived statistics. Actual adjustment values vary significantly by market, price tier, and property type. For final offer decisions, verify adjustment rates with a local agent or appraiser.
ARV $/sqft ranges shown in this calculator are synthesized from multiple industry sources, including Zillow Research regional price data, Redfin Market Insights, local MLS sold data, appraisal institute methodology, and 2026 market rate surveys. All adjustment defaults are based on Fannie Mae appraisal guidelines and appraiser convention.
Disclaimer: This ARV Calculator approximates market value for screening purposes only. Results are estimates with inherent uncertainty and should not be used as a substitute for a licensed appraisal or Broker Price Opinion (BPO). Lenders will not accept this tool's output for loan underwriting.
