What does ARV mean in real estate?

ARV is after repair value: what the property is worth once the planned renovation is complete. It is the basis for the offer, the loan amount, and the profit projection, so an error in ARV moves all three at once.

How do you calculate ARV?

Find three to five sold comparable properties in the same submarket, closed within six months, similar in size, age, and style. Adjust each for meaningful differences, then take the tightest cluster. It is a judgement, not a formula.

Can I use Zestimate or an automated valuation for ARV?

No. Automated valuations are built from tax records and prior sales, so they price the property roughly as it is, not as it will be. Use them to sanity check a finished number, never to produce one.

How far away can comparable sales be?

Stay inside the same submarket, ideally under half a mile in a dense area and inside the same school and tax district anywhere else. Crossing a boundary that buyers care about invalidates the comparison regardless of distance.

How to calculate ARV without fooling yourself

After repair value is the number every other number depends on. Here is how to build one from comparable sales, and the five ways it gets inflated.

July 23, 2026 · 4 min read

Every number on a flip depends on this one. The offer comes from it. The loan amount comes from it. The profit projection is the difference between it and everything you spend.

Which means an optimistic ARV does not produce a slightly optimistic deal. It produces a deal that was never there, discovered five months later when the property will not sell.

What ARV actually is

After repair value is what the property sells for once your planned work is finished, in the current market, to a normal retail buyer.

Three parts of that sentence do real work:

Your planned work. Not a full luxury renovation, the specific scope you have budgeted. If your comparables have finished basements and quartz, and your budget has neither, they are not your comparables.

Current market. Not the market when you list. Nobody can price the future, so you price today and treat any movement as risk rather than as plan.

Retail buyer. Not another investor, not a family member. The buyer who finances with a conventional loan and needs the appraisal to support the price.

Building the number

Find sold, not listed

Listings are asking prices. They are evidence of hope. Use closed sales only.

Pending sales are the best leading indicator you can get, because a price was agreed, but you will not see the final figure until it records.

Set the boundaries before you look

Decide the rules first, then search. Deciding after you have seen the prices is how the number gets chosen rather than calculated.

Reasonable starting bounds:

Distance. Under half a mile in a dense area. Same subdivision if there is one. Never across a boundary buyers care about: a school district line, a town line, a rail corridor, a major road.
Time. Closed inside six months. Twelve if the area is thin, with an explicit note that you are stretching.
Size. Within about 20% of finished square footage.
Type and era. A 1920s row home is not comparable to a 1998 colonial at the same square footage.

Adjust honestly

You will not find identical properties. Adjust for what buyers actually pay for: bedroom and bathroom count, garage, finished basement, lot size, and condition.

Adjust toward your subject. If a comparable has one more bathroom than your finished product will, its price is higher than yours should be, so adjust it down. The most common error is adjusting the comparables up to justify the answer already decided on.

Take the cluster, not the average

With five adjusted comparables, three will usually sit close together and two will sit outside. The tight cluster is your ARV. The outliers are telling you something specific happened in those transactions, so find out what before you let either one move your number.

Averaging all five lets a single unusual sale drag the answer.

The five ways ARV gets inflated

1. The best comparable is the one that sold highest. It gets remembered and the others get discounted. Write all of them down before you start reasoning.

2. The renovation is priced above the budget. The comparables were fully renovated. Your scope is paint, floors, kitchen, and one bathroom. Those are not the same product.

3. Crossing a boundary. Two streets apart and a different school district is not two streets apart in a buyer's mind.

4. Stale sales in a moving market. A sale from fourteen months ago is a different market. In a falling one it is optimistic; in a rising one it is leaving money behind. Either way it is not evidence about today.

5. Adding the rehab budget to the purchase price. Spending $60,000 does not add $60,000 of value. Some scopes return more than they cost and many return less. Value comes from the comparables, never from the receipts.

Sanity checks worth running

Price per finished square foot. Compute it across your comparables. If your ARV lands well outside their range, something is wrong.
The ceiling test. What is the highest price any property on that street has ever achieved? Exceeding a street's ceiling requires a real reason.
Ask an agent who lists there. Not what they think it is worth. Ask what they would list it at, and what it would appraise for. Those are different answers and both are useful.
Assume you are 5% high. Rerun the deal at 95% of your ARV. If the project only works at your original number, you have no margin at all.

Then run it through the real costs

An honest ARV is the start. The deal is decided by what remains after financing, both closings, carry across the hold, and roughly 6% to sell.

That is what the flip calculator charges against your numbers, and it is usually the gap that first projects miss. If you want a fast filter before you get that far, the 70% rule will tell you whether a property is worth an hour of this work at all.
