ARV (After Repair Value)
Quick Definition
After Repair Value (ARV) is the estimated market value of a property after all planned renovations and repairs are finished. Real estate investors, particularly fix-and-flip buyers, use ARV as the anchor for every deal calculation: how much to pay, how much to spend on rehab, and how much profit to expect. The number is not a guess. It is derived from recent sales of comparable renovated properties in the same market.
What It Means
ARV answers the single most important question in a flip: what will this house sell for once the work is done? Get that number wrong and every other calculation, from offer price to rehab budget to profit, is wrong too. Overestimate ARV and you overpay, overspend, and walk away with a loss. Underestimate it and you pass on deals that would have been profitable.
The ARV figure is built on comparable sales, the same data a real estate agent uses in a comparative market analysis. The difference is that a CMA values a property in its current condition, while ARV values it in its future, renovated condition. That means the comps must be renovated homes of similar quality, not distressed properties that still need work.
In 2026, ARV discipline matters more than it has in years. The housing market has cooled. According to ATTOM's Q1 2026 Home Flipping Report, the typical home flip sold for a gross profit of $66,000, with gross ROI of 25.4%. That is up slightly from the prior quarter but well below the 29.6% ROI recorded a year earlier. Margins have compressed as purchase prices rose and buyers became pickier. The typical flip now takes 165 days from purchase to sale, up from 160 days the previous quarter. Cash purchases dominate, accounting for more than three in five flips nationwide.
Renovation costs have climbed too. ATTOM data shows average rehab costs reached $79,000 per project nationally in Q1 2026. Material prices rose 6.7% on average since March 2026, according to the National Association of Home Builders' Q2 2026 Remodeling Market Index. Those rising costs squeeze the spread between purchase price and ARV, making accurate ARV estimates the difference between profit and a loss.
How It Works
Calculating ARV follows a structured process. Here is how experienced investors arrive at the number.
Step 1: Pull Comparable Sales
Search the MLS or public records for homes that have sold in the past 3 to 6 months within a tight radius of the subject property, typically 0.5 to 1 mile in urban areas. The comps must be:
- Similar in square footage, within 10 to 15% of the subject property
- Similar in bedroom and bathroom count
- Similar in lot size and style
- Renovated or in good condition, not distressed
The last point is what separates ARV comps from a standard CMA. You are valuing the finished product, so you need sales of finished products.
Step 2: Calculate Price Per Square Foot
For each comp, divide the sold price by the square footage to get a price per square foot. Average those figures across your best 3 to 6 comps.
Step 3: Apply to Subject Property
Multiply the average price per square foot by the subject property's finished square footage. If the renovation will add square footage, use the post-renovation figure.
Step 4: Adjust for Differences
No two homes are identical. Adjust the ARV up or down for features that differ from the comps: an extra bathroom, a larger lot, a better school district, superior finishes. A pool adds more value in Phoenix than in Minneapolis. A garage matters more in snowbelt markets.
The ARV Formula
ARV = Average Price Per Square Foot of Renovated Comps x Subject Property Finished Square Footage +/- Adjustments
The 70% Rule
Once you have ARV, the 70% rule tells you the maximum you should pay for the property before repairs:
Maximum Purchase Price = (ARV x 0.70) - Estimated Repair Costs
The 30% buffer is not all profit. It covers:
- Profit margin: 10 to 15%
- Agent commissions on the sale: 5 to 6%
- Closing costs on the buy and the sell: 2 to 3%
- Holding costs (taxes, insurance, utilities, financing): 3 to 5%
- Contingency for surprises: 2 to 3%
According to the Q1 2026 JBREC + Kiavi Fix and Flip Survey, the national weighted average purchase price sits at roughly 67% of ARV, down slightly from a year earlier. About 37% of surveyed flippers reported being willing to pay 60% or less of ARV to acquire a property, reflecting tighter margins and more cautious underwriting.
Real-World Examples
Example 1: A Standard Flip
You find a 1,800 square foot, 3-bedroom, 2-bathroom house in a stable suburban neighborhood. It needs a full cosmetic renovation: kitchen, bathrooms, flooring, paint, and landscaping. The asking price is $220,000.
You pull six renovated comps within 0.75 miles that sold in the past 4 months:
| Comp | Sold Price | Sq Ft | Price/Sq Ft |
|---|---|---|---|
| 12 Maple St | $365,000 | 1,850 | $197 |
| 34 Oak Ave | $352,000 | 1,780 | $198 |
| 56 Pine Rd | $378,000 | 1,920 | $197 |
| 78 Elm Ct | $360,000 | 1,810 | $199 |
| 90 Birch Ln | $370,000 | 1,860 | $199 |
| 23 Cedar Dr | $355,000 | 1,790 | $198 |
Average price per square foot: $198
ARV calculation: $198 x 1,800 sq ft = $356,400
After adjustments (subject has a slightly smaller lot than average, subtract $4,000): ARV = $352,400
Estimated repair costs: $55,000 (cosmetic renovation, no structural issues)
70% rule check: ($352,400 x 0.70) - $55,000 = $246,680 - $55,000 = $191,680 maximum purchase price
The asking price of $220,000 is above your maximum. You would need to negotiate down to around $190,000 to make the deal work, or walk away.
Example 2: A High-End Flip in Denver
ATTOM and Backflip's Q1 2026 market analysis found that Denver stands out for large-scale projects. The average construction budget reached $431,250, with an average after repair value of $1.255 million. The average payoff period was 133 days, reflecting longer project timelines despite the higher property values.
For a Denver investor, the math looks different. On a $1.255 million ARV with $431,250 in rehab costs:
70% rule check: ($1,255,000 x 0.70) - $431,250 = $878,500 - $431,250 = $447,250 maximum purchase price
That leaves a gross spread of $807,750 between purchase plus rehab and the ARV, but selling costs on a $1.255 million home (agent commissions, closing costs, holding costs) can eat $90,000 or more, and financing costs on a project of this scale are significant.
Example 3: A Tight Margin Market
Dallas-Fort Worth showed the clearest compression in margins in Q1 2026. The average purchase price of $418,856 and average flipped price of $437,003 left just $18,147 in average gross profit and a 4.3% ROI. Once you account for rehab costs, holding costs, and selling costs, most of these deals lose money. This is what happens when investors overpay relative to ARV or overestimate the ARV itself.
Key Points to Remember
- ARV is based on renovated comparable sales, not distressed properties or active listings.
- The 70% rule is a screening tool, not a guarantee of profit. Run full deal analysis before committing.
- Renovation costs averaged $79,000 per flip nationally in Q1 2026, and material inflation is pushing them higher.
- Gross flipping ROI was 25.4% in Q1 2026, down from 29.6% a year earlier. Margins are tightening.
- About 28% of flips break even or lose money, according to industry data. Accurate ARV is the main defense against joining that group.
- Price per square foot is the starting point, but adjustments for condition, location, and features can move ARV by 5 to 15%.
- The longer a flip takes, the more holding costs eat into profit. The typical flip took 165 days in Q1 2026.
Common Mistakes to Avoid
- Using active listings as comps: Asking prices are wishes, not facts. Only closed sales reflect what buyers actually paid. In 2026's softer market, many listings are selling below asking, so list prices overstate value.
- Cherry-picking the best comps: Selecting only the highest sales to justify a higher ARV is a classic error. Use the full range of comparable sales and let the average speak.
- Ignoring market direction: In a declining market, comps from 6 months ago may overstate today's value. Realtor.com reported list price per square foot fell 2.1% year over year nationally as of June 2026, with declines in 33 of the top 50 metros. Apply downward time adjustments to older comps.
- Underestimating repair costs: Rehab budgets overrun on most projects. Experienced investors add a 15 to 20% contingency. Hidden issues behind walls, under floors, and in foundations surface constantly.
- Forgetting holding and selling costs: The 70% rule bakes these in, but investors who skip the rule and just subtract rehab from ARV often forget the $20,000 to $40,000 in commissions, closing costs, taxes, insurance, and utilities that pile up over a 5 to 6 month project.
- Over-renovating for the neighborhood: Putting $80,000 of luxury finishes into a neighborhood where homes sell for $250,000 does not push ARV to $330,000. Buyers will not pay for upgrades that exceed neighborhood norms. Match your renovation quality to the comps.
Related Concepts
ARV sits at the center of fix-and-flip math, but it connects to several other tools investors use. A formal appraisal is what a lender orders to verify value, and your ARV estimate should be close to what an appraiser will conclude. The comparative market analysis uses the same comp-pulling methodology, just applied to current condition rather than post-renovation condition. For buy-and-hold investors, the cap rate and cash on cash return matter more than ARV, since rental income drives those returns rather than resale value. Every flip also involves closing costs on both the purchase and the sale, plus a down payment if you are financing. Investors working in the broader real estate space should understand how ARV interacts with commercial real estate valuations, which use income approaches rather than comparable sales.

Frequently Asked Questions
Q: How accurate does my ARV estimate need to be? A: Within 5% is the target for experienced flippers. On a $350,000 ARV, that is a $17,500 range. Being off by 10% means a $35,000 swing, which can erase your entire profit margin. The more comps you have and the closer they are in location, size, and condition, the tighter your estimate will be.
Q: Can I use Zillow's Zestimate as my ARV? A: No. Automated valuations like Zestimates are estimates of current market value, not post-renovation value, and they carry significant error margins. Zillow itself reports a median error rate of 2.4% for on-market homes and 7.5% for off-market homes. Use actual closed sales of renovated comparable properties, pulled from the MLS or your agent.
Q: What if there are no renovated comps in the area? A: This is common in distressed neighborhoods where few flips have happened. You can widen your search radius, use comps from a similar neighborhood nearby, or estimate the cost to renovate and add that to a current-condition comp. Some investors use the cost approach: land value plus replacement cost minus depreciation. In these cases, be conservative and add a larger contingency buffer.
Q: Does ARV apply to rental properties, or just flips? A: ARV is primarily a flip metric, but buy-and-hold investors use it too. The after repair value tells you what the property is worth once improved, which matters for refinancing out of a hard money loan into a long-term mortgage. The BRRRR strategy (Buy, Rehab, Rent, Refinance, Repeat) depends on ARV to determine how much you can pull out at refinance.
Q: How do I account for a softening market when estimating ARV? A: In 2026's declining price environment, weight your most recent comps heaviest and apply a downward time adjustment to older sales. If prices in your market are falling 2 to 3% year over year, a comp that sold 6 months ago at $350,000 might only support $345,000 today. Be conservative. It is better to underestimate ARV and pass on a marginal deal than to overestimate it and lose money.
