How to Calculate ARV (After-Repair Value) With Comps

ARV — after-repair value — is the number every other number in a wholesale deal depends on. Get it right and your offers make sense to buyers. Get it wrong by 10% and you will either lose the seller or hand your buyer a loss. Here is how to calculate ARV the way appraisers and experienced flippers do, step by step, with a worked example you can copy.

What ARV is

ARV is what the property will sell for on the open market once it is fully renovated to the standard of the neighborhood. It is not what it is worth today, and it is not what the seller thinks it is worth. It is the price a retail buyer with a mortgage will pay for the finished product.

That last part matters. Most retail buyers finance their purchase, which means an appraiser will eventually look at the finished house and decide whether the price is supported. If your ARV is higher than what an appraiser would sign off on, your end buyer’s resale falls apart, and they will remember who sold them the deal. Thinking like an appraiser from the start keeps your numbers in line with how the property will actually be valued when it sells.

Why ARV drives the whole deal

Your cash buyer works backward from ARV. They subtract their repair budget, holding costs, closing costs, and the profit they need, and what is left is the most they will pay you. Every dollar of ARV error flows straight into that math. An ARV that is $30,000 too high does not make a deal $30,000 better; it makes a deal that looks good on paper and fails when a buyer runs their own comps. With ATTOM reporting a typical flip gross margin of 21.5% in Q2 2026, buyers have little room to absorb that kind of error. It also shapes your conversations with motivated sellers: when you can explain how you arrived at the finished value, your offer reads as a calculation rather than a lowball.

How to calculate ARV with the comparable-sales method

Find three to five recently sold properties that match the subject and average them. The rules that keep you honest:

Sold, not listed. Active and pending listings are asking prices. Only closed sales are evidence.
Within 0.5 miles in a city, up to a mile in the suburbs, and in the same school district or subdivision if possible.
Within 6 months. Markets move. Stretch to 12 months only if there is nothing else, and note it.
Same type and size: same bed and bath count, within about 20% of the square footage, same style (single-story vs. two-story), similar lot.
Renovated condition. You want comps that were updated, because that is what your buyer will produce.

Two more boundaries are worth respecting. Do not cross a major road, rail line, or highway to grab a comp if the other side prices differently, and do not mix property types: a townhouse is not a comp for a detached house even if the square footage matches.

Step-by-step: from address to ARV

Record the subject’s facts. Beds, baths, square footage, year built, lot size, garage, basement, and style. Pull these from the county record and confirm them on your walkthrough, because county data is sometimes out of date.
Draw your search area. Start at a quarter to half mile and widen only if you cannot find enough sales.
Filter for sold properties in the last six months that match on bed and bath count and fall within about 20% of the subject’s size.
Check condition in the photos. Keep the ones that were clearly updated: newer kitchen, updated baths, fresh flooring. Set aside the dated or distressed sales; those tell you as-is value, not ARV.
Adjust each comp toward the subject (see the next section).
Weight and reconcile. Average the adjusted values, leaning toward the comps that needed the fewest adjustments.
Write it down with your reasoning, so you can explain your number to a buyer in one sentence per comp.

Adjusting the comps

No comp is a perfect match. Adjust each one toward the subject: subtract for a garage the subject does not have, add for a bathroom it has that the comp lacks, adjust for square footage using the neighborhood’s price per square foot. Then take the average, or lean toward the comps that are the closest match. If your three best comps are $395,000, $402,000, and $410,000, your ARV is about $400,000 — not $410,000 because you want the deal to work.

A simple rule: always adjust the comp, never the subject. If the comp is better than your house in some way, bring the comp’s price down. If it is worse, bring it up. The dollar value of each feature varies by market, so ask an agent or an active flipper what a garage, an extra bathroom, or a pool typically adds where you are working, and keep those figures in a notes file. Be careful with square-footage adjustments too: using the full price per square foot on a small size difference tends to overstate it, so many investors apply a smaller per-foot figure for the difference.

A worked example

The figures below are an example to show the method, not market data.

Subject: 3 bed / 2 bath, 1,450 sq ft, 1978, needs a full cosmetic update.
Comp A: 3/2, 1,400 sq ft, renovated, sold 2 months ago at $398,000.
Comp B: 3/2, 1,520 sq ft, renovated, sold 4 months ago at $412,000 (adjust down ~$8,000 for size).
Comp C: 3/2, 1,430 sq ft, renovated, sold 5 months ago at $395,000.
Adjusted average: roughly $399,000. Call the ARV $400,000.

Notice what did not happen. Comp B sold for the most, but it is also the biggest house, so it gets adjusted down instead of being used as the headline number. Comp A is the most recent and closest in size, so if you had to pick one comp to lean on, it would be that one. A buyer reading this breakdown can follow every step, and that is what makes them trust your deal sheet.

Where to find comps

An agent on your buyer’s list can pull MLS sold data for you in five minutes, and that is the gold standard. Public alternatives: Zillow and Redfin sold filters (check the sold date and condition photos), county records, and paid tools like PropStream. Never rely on an automated “Zestimate” for ARV.

In states where sale prices are not recorded publicly, sold data outside the MLS can be thin or missing, which makes an agent relationship even more valuable. Your state guide is a good place to check how records work where you are buying.

Adjusting ARV for market direction

Comps describe the past; your buyer sells in the future. If prices in the area have moved since your comps closed, adjust for it. Fannie Mae’s appraisal guidance allows time adjustments but requires them to be explained and supported by market evidence, and investors should hold themselves to the same standard.

Practical ways to measure direction:

Compare recent sales with older ones. If renovated three-bedroom homes sold for about $260,000 nine months ago and about $250,000 in the last two months, the trend is down, and your older comps need a negative adjustment.
Watch the listings. Rising days on market, price cuts, and more active listings than pending sales all point to softer prices.
Check a broad index for context. The FHFA House Price Index tracks single-family price movement by state and metro. It is too broad to price one house, but it shows whether your local comps are moving with or against the wider market.

In a rising market, resist the urge to add an aggressive upward adjustment. Buyers will pay for prices that already exist, not prices you expect. In a falling market, build in a margin, because your buyer will resell months after you assign the contract.

ARV for properties that break the usual rules

Some property types need a different approach to after-repair value.

Condos and townhomes

Use sales from the same complex or a directly competing one whenever possible. HOA fees, special assessments, and rules on renting can change value more than the finishes inside the unit.

Small multifamily

For duplexes through fourplexes, check ARV against income. If renovated rents and realistic expenses do not support your sales-based ARV, buyers will pay closer to the income value. Our guide to real estate comps covers how to pull rent comps alongside sales comps.

Rural homes

Expect fewer sales and longer distances. Widen the search in time and miles, explain each choice in your deal sheet, and adjust carefully for acreage, wells, septic systems, and outbuildings.

Houses with a major defect

If the after-repair plan does not fix a defect such as a busy-road location or a layout with a bedroom reached only through another bedroom, your ARV must reflect it. Renovated finishes do not erase a permanent location or design problem.

When ARV is the wrong anchor

ARV is the right starting point for flips and many rental purchases. It is the wrong one in a few situations:

Teardowns and lots: when repair costs approach the value of a renovated home, buyers price the property as land minus demolition cost.
Larger rentals: buildings with five or more units trade on net operating income and cap rates.
Very thin markets: with only one or two relevant sales in a year, any single ARV figure is a guess, and a wide range is more honest.

Common ARV mistakes

Using the highest comp. The top sale is usually the best-finished house on the best street. Your buyer will not assume they can beat it.
Mixing renovated and distressed sales. Averaging a flipped house with a foreclosure gives you a number that describes neither.
Ignoring the date. A comp from a year ago may reflect a different market. If you must use it, say so on the deal sheet.
Over-improving on paper. Assuming a finish level above the neighborhood standard inflates ARV. Buyers renovate to what the area supports.
Trusting listing descriptions. “Fully updated” can mean new paint. Look at the photos.

ARV checklist before you make an offer

At least three sold comps, renovated, within six months and a half mile (or noted exceptions)
Same property type, bed and bath count, and similar size and style
Each comp adjusted toward the subject, with the adjustment written down
Final ARV at or below the middle of the adjusted range
Number sanity-checked with an agent or a buyer when you are unsure

From ARV to your offer

Once you have ARV, the rest is arithmetic: ARV × 70% − repairs − your fee is your maximum allowable offer. The full MAO walkthrough is here, and the repair estimate guide is here.

Using the example above: $400,000 × 70% = $280,000. If repairs are estimated at $45,000 and you want a $10,000 assignment fee, your maximum offer is $225,000. Your buyer’s price is $235,000. Change the ARV to $410,000 and that maximum offer moves up by $7,000, which is why a careful ARV matters more than any negotiating trick. Before you send numbers out, make sure you have cash buyers lined up who can tell you whether your ARV matches what they see.

ARV FAQ

How many comps do I need to calculate ARV?

Three is the minimum and five is better. Fewer than three and a single unusual sale can skew your number; more than five and you are usually reaching for comps that do not match well. Whatever the count, drop sales between relatives or related companies, because non-arm’s length sales are not evidence of market value.

What if there are no renovated sales nearby?

Widen the time window before you widen the distance, and note every exception. If you still cannot find support, the deal carries more risk and your offer should reflect it. Ask a buyer who works that area what they would expect the finished house to sell for.

Is ARV the same as an appraisal?

No. An appraisal is a formal valuation by a licensed appraiser. ARV is your estimate of future value using the same comparable-sales logic. The closer your method is to theirs, the fewer surprises your buyer will face at resale.

Should I share my comps with buyers?

Yes. Listing the comps and adjustments on your deal sheet lets a buyer check your work quickly, and it builds the credibility that gets your next deal looked at first. It also pairs well with a clear wholesale contract so the buyer knows exactly what they are stepping into.

How often should I update an ARV?

Update it whenever new sales close nearby, and at least before every offer and again before you market the deal. In a fast-moving market, an ARV from two months ago can already be stale.

What ARV will a lender use?

A lender relies on its own appraisal, not your estimate. Hard money lenders often order an after-repair valuation based on the rehab scope, so share your repair plan and comps with your buyer to help them anticipate the appraisal.

Can the ARV be lower than the purchase price plus repairs?

Yes, and that is a sign the deal does not work at that price. Either renegotiate, change the exit strategy, or walk away. No assignment fee is worth handing a buyer a loss.

Should my ARV match the buyer’s ARV?

Not exactly, but it should be close. Experienced buyers run their own numbers, and a gap of a few percent is normal. If your ARV is consistently higher than what your buyers calculate, review which comps you are choosing and whether your adjustments lean optimistic. Ask a trusted buyer to walk through their comps with you after a deal falls through; that feedback is one of the fastest ways to sharpen your valuations.

If you are ever unsure about an ARV, send the address and your comps to a buyer on your A-list and ask what they would pay finished. Their answer is the market.

Why accurate ARV matters more in 2026. Flip margins have fallen sharply, according to the data in our State of Wholesaling 2026 report, so buyers check your numbers closely. ARV also drives other strategies: it sets the spread in a novation deal and decides whether a house suits a wholesale or a flip.
