How ARV Is Determined, and Why 75% Decides Your Deal

Every fix-and-flip loan is sized off one number, and it is a number you do not control. After-repair value is a licensed appraiser's opinion of what the property will be worth once the work in your scope is finished. The lender orders it, the lender's process controls it, and your own estimate is treated as an input to be tested rather than a fact to be accepted. Operators who understand that run their numbers against a conservative ARV before they write an offer. Operators who do not find out at the appraisal, ten days before closing, that the capital stack has a hole in it.

The second thing to understand is why lenders cap total proceeds somewhere near seventy to seventy-five percent of that value rather than lending close to it. The cushion is not caution for its own sake. It is a reserve against the cost of a bad outcome: a sale that has to happen fast, at a discount, with commission and closing costs coming out of the proceeds first. This guide covers how the number is built, what the cushion pays for, and the arithmetic that tells you whether a deal fits before you commit earnest money.

What ARV actually means

After-repair value is a hypothetical: what this property would sell for on the open market, in a reasonable exposure period, in the condition your scope describes. It is not your target list price, and it is not the as-is value plus your rehab budget. That last misunderstanding costs operators more money than any other.

Money spent does not convert to value one for one. A forty thousand dollar kitchen in a submarket where every finished comparable sold with a mid-grade kitchen adds the value of a mid-grade kitchen. The rest is a gift to the buyer. Appraisers value the property against what the market paid for similar finished houses, not against your invoices, and when a file shows rehab spend far above the lift the comps support, the desk reads it as an operator who over-improved.

Who produces the number

Your own ARV is an underwriting input and nothing more, though it carries real signal: a borrower whose estimate lands within a few percent of the appraisal deal after deal earns credibility, and one who is consistently ten percent high gets discounted automatically on every later file. Your agent's broker price opinion is fast, cheap, and produced by someone whose pay depends on the transaction closing: useful for a preliminary sizing conversation, rarely enough to fund on.

The opinion that sizes the loan is the appraisal, and on rehab files the assignment is usually subject-to-completion: the appraiser inspects the property as it stands, reads your scope, and reports two values. As-is today often constrains how much of the purchase the lender will advance. As-repaired sets the ceiling on total proceeds. Both matter, and borrowers who only ask about the second one get surprised by the first.

How the comp set is built

The as-repaired opinion is a sales comparison analysis: recent closed sales of finished properties similar to yours, adjusted for their differences, reconciled to a value. The constraints on that search are what determine whether the number in your head is even supportable. Standards vary by market and appraiser, but the usual expectations are consistent.

• Closed sales, generally within the last three to six months. Active listings are asking prices, not evidence.
• Tight proximity: often half a mile to a mile in suburban markets, tighter in dense urban grids.
• Living area broadly within about twenty percent of the subject. Large size gaps require adjustments big enough to weaken the comparison.
• Similar bed and bath count, story count and lot character. Buyers price the floor plan, not just the footage.
• Finished condition comparable to your completed scope. A renovated subject cannot be supported by tired comps.
• Same side of the boundaries that matter: school attendance zone, major arterial, rail line, municipal border.

What the twenty-five percent cushion pays for

Once ARV is established, a short-term lender lends to a percentage of it, commonly written as LTARV. The gap between that loan and the value is not padding, and itemizing it is worthwhile because the same arithmetic is what protects you.

• Disposition cost. A forced sale still pays commission, title, transfer tax and closing costs, frequently six to nine percent of the price before a dollar comes back.
• Time. Carry, taxes, insurance and legal cost accrue while a distressed asset sits.
• Completion risk. A project stopped mid-rehab is worth less than as-is value, because the next buyer prices in the mess as well as the work.
• Valuation error. Every appraisal is an opinion with a range around it.
• Market movement. Paper written today may be sold into a different market twelve months out.

Add those up honestly and the cushion stops looking generous. It is roughly the amount of value that evaporates when a project goes wrong, and it is the same reserve standing between you and a personal loss if you have to exit early.

Two ceilings, and the lower one wins

Almost every rehab file is sized under two constraints at once. Loan-to-cost advances a percentage of purchase price plus some or all of the documented rehab budget. Loan-to-after-repair-value caps total proceeds at a percentage of ARV. Both are tested, and the lender funds the smaller result.

Now move the appraised ARV to $370,000 and hold everything else constant. The value test becomes $277,500 (nineteen thousand below the cost test) so the loan drops to $277,500 and that shortfall becomes cash you have to bring on top of the down payment. This is the most common way a flip breaks between contract and funding, and it is entirely predictable if you run both tests before you sign.

What legitimately moves the number

Some scope items reliably show up in the value opinion. Permitted, finished, heated square footage moves value, because footage is the dominant adjustment in the grid. A legally permitted bedroom or full bath moves value, sometimes substantially, because it moves the property into a different search filter. Taking a property from distressed condition to market-normal moves value, because it makes the whole finished comp set applicable. Correcting a functional defect: a walk-through bedroom, a bath reachable only through the primary suite: removes a discount.

Finish upgrades beyond the neighborhood standard and mechanical replacement generally do not move the appraised number the way operators expect. A new furnace does not add its cost to value; it removes a deduction and a buyer objection. That is a real purpose. It is not value creation, and underwriting it as such is how spreads disappear.

Building an ARV support package

You cannot dictate an appraisal, but you can make it easy to reach a defensible number. An organized package does not inflate value; it prevents an under-supported one, which is the more common problem.

Where to start

Before your next offer, pull three to five closed sales of finished properties inside the tightest boundary you can defend: same tract, same school zone, same footage band, last four months. Take the conservative end of that range. Multiply by the value cap you expect, subtract your rehab budget and an allowance for financing and carry, and see what purchase price the deal actually supports.

Then run both sizing tests at that price. Knowing which one binds tells you what to negotiate: if cost binds, price and scope are your levers; if value binds, you are betting on an appraisal, and that bet is worth pricing before you sign rather than ten days from closing.
