ARV — After Repair Value
ARV — After Repair Value
ARV is your forecast of what the property will appraise for once improvements are complete—and it is the linchpin of every BRRRR deal.
Key takeaways
- ARV is not your opinion; it is the market value of an identical, fully repaired property in the same neighborhood, supported by comparable recent sales and rental income.
- Conservative ARV estimates are the single biggest predictor of successful BRRRR deals; aggressive estimates are the single biggest cause of trapped equity and failed refinances.
- ARV is derived from two independent methods: comparable sales (recent arms-length transactions of similar properties) and income approach (rental income capitalized by the market cap rate).
- The most reliable ARV incorporates both methods and builds in a 10–15% safety discount, especially in volatile or unfamiliar markets.
- Lenders will order a professional appraisal post-rehab; if your ARV forecast is optimistic, the appraisal will reveal it, jeopardizing the refinance and your capital recovery.
What ARV is not
Many new BRRRR investors confuse ARV with "what I think the property could be worth" or "what I would sell it for if I wanted to make profit X." ARV is neither. It is a disciplined estimate of fair market value—the price a typical investor would pay for the property post-rehab if it were listed for sale and marketed normally. It is the value an independent appraiser would assign, without emotion or aspirational thinking.
ARV also is not affected by your cost basis. If you bought the property for $150,000 and will invest $35,000 in rehab, your total investment is $185,000. That is sunk cost. ARV is determined by what comparable properties sold for and what the market rents support—not by your out-of-pocket dollars. Conflating cost and market value is a common trap. A property that costs $185,000 to acquire and rehab may appraise for only $190,000 in a weak market; the deal is still underwater, regardless of your good faith effort.
Comparable sales method
The most straightforward way to estimate ARV is to find recent arm's-length sales of comparable properties in the same neighborhood. Comparables (or "comps") are properties that are:
- Same property type (single-family homes to single-family homes; duplexes to duplexes).
- Same or very similar condition post-repair (not distressed, not luxury—market-grade).
- Same neighborhood (within 1–2 miles; same school district if applicable).
- Sold in the last 90 days (or up to six months if the market is slow).
Each comp should be adjusted for meaningful differences. If your target property has three bedrooms and a comp has four, the four-bedroom typically sold for more. If your property is in a quieter block and the comp is near a highway, your property may be worth a premium. Adjustments are typically $2,000–10,000 per significant factor (an extra bedroom, an updated kitchen, a garage).
For a property in a suburban market where recent comps are abundant, you want at least 3–5 comps within 10% price variance. If three recent arm's-length sales of similar three-bedroom homes sold between $215,000 and $225,000, your ARV estimate is confidently $215,000–225,000.
The comparable sales method is precise in established markets with recent transaction history but unreliable in thin markets (few recent sales) or rapidly appreciating markets (old comps are stale). In 2021–2022, fast-appreciating markets saw homes gain 15–20% per year; a comp from six months prior was often $20,000–30,000 out of date.
Income approach method
The income approach estimates value based on the rental income the property generates. The formula is straightforward:
ARV = Annual Rent ÷ Cap Rate
A property renting for $1,400 per month ($16,800 annually) in a market where cap rates are 7.5% implies an ARV of $224,000 ($16,800 ÷ 0.075). This is the income-based valuation method used by appraisers and investors alike.
The trick is pinpointing the market cap rate. Cap rates vary by neighborhood, property type, and tenant profile. In a suburban market with stable rents and low vacancy, cap rates might be 6–7% (higher property values, lower rent yields). In a secondary market with higher turnover, cap rates might be 8–10%. The cap rate is influenced by local supply and demand, quality of the tenant base, and interest rate environment.
You can infer the market cap rate by analyzing recent rental property sales. If a landlord bought a rental property generating $1,200 monthly rent for $180,000, the implied cap rate is 8% ($14,400 ÷ $180,000). By collecting several such sales, you triangulate the typical cap rate for the neighborhood.
Alternatively, you can reference national averages, which cluster around 7–8% for stable single-family rentals in Sunbelt markets and 5–6% in coastal markets with lower cap rates due to appreciation expectations. However, local data is always more reliable than a national average.
The income approach is particularly useful for confirming comp-based ARV. If comparable sales suggest $220,000, and the rental income approach (using market cap rate) also supports $215,000–225,000, your ARV is well-anchored.
Triangulating ARV: a worked example
Suppose you are analyzing a property in an Austin, Texas suburb. The as-is property is worth $145,000 (lender appraisal). Post-rehab, you forecast rental income of $1,350 per month. You gather three comparable sales:
- 3-bed, 2-bath home (similar condition) sold eight weeks ago for $225,000.
- 3-bed, 2-bath home (slightly better kitchen) sold six weeks ago for $232,000; adjust down $6,000 → $226,000.
- 3-bed, 2-bath home (slightly smaller lot) sold 12 weeks ago for $218,000; adjust up $3,000 → $221,000.
Comparable average: ($225,000 + $226,000 + $221,000) ÷ 3 = $224,000.
Income approach: Local rentals suggest a 7.5% cap rate. $1,350 × 12 ÷ 0.075 = $216,000.
Your estimate: The comp-based and income-based approaches suggest $216,000–224,000. You conservatively use $215,000 as your ARV.
With a purchase price of $150,000 and rehab budget of $35,000, your total investment is $185,000. Your projected equity post-refinance is $215,000 − $165,000 (80% LTV refinance) = $50,000. The 75% rule: $185,000 ÷ $215,000 = 86%. You exceed the 75% target, so you negotiate down to $145,000 purchase price, bringing the ratio to 84%—still tight, but acceptable if rehab is well-managed.
Common ARV estimation errors
Overestimating comps: Choosing the most expensive recent sale rather than the median. If properties range $215,000–235,000, using the $235,000 outlier skews your estimate high.
Using outdated comps: In appreciating markets, a sale from 12 months ago is substantially lower than today's market. Always prioritize sales from the last 60–90 days.
Overweighting cosmetics: New paint, updated fixtures, and landscaping appeal emotionally but add $5,000–15,000 to value, not $30,000. Resist the urge to assume buyers will pay a premium for your particular rehab choices.
Ignoring cap rates: Assuming your property will rent for market rate without validating market cap rates leaves you unanchored. If the market cap rate is 8% and you forecast 7.5%, you are implicitly assuming better-than-market characteristics.
Anchoring to your cost basis: A property that costs $185,000 to acquire and improve is worth what the market will pay, not what you spent. If the market pays $190,000, the deal is marginal, not a home run.
Neglecting comparable age: A comp sold in Q2 is more relevant than one sold in Q4 of the prior year. Trends matter, especially in fast-moving markets.
Using ARV conservatively
The best practice is to use the lower bound of your range. If comps suggest $220,000–230,000, use $215,000. If the income approach suggests $210,000–220,000, use $210,000. This 10–15% safety margin protects you when the appraiser pulls the comp similar to yours and finds a recent arm's-length sale at $212,000 instead of $225,000, or when the lender's appraiser adjusts rental income for expected vacancy or caps the rent estimate.
Professional appraisers often apply conservative adjustments. Rental income is sometimes capped at 95% of your lease (vacancy buffer). Cap rates used by appraisers may be 0.5–1% higher than market (more conservative). These adjustments are standard and should be anticipated in your ARV forecast.
