ARV Appraisals: How After-Repair Value Is Actually Determined

Every fix-and-flip term sheet leads with a percentage of ARV — after-repair value — and most borrowers treat that number as something they already know from their own comps. The lender does not. ARV, for loan purposes, is produced by a specific appraisal process with rules about condition assumptions, comparable selection, and review, and the loan is sized to the appraiser's number, not yours. Understanding how that number gets made is the difference between a financing plan and a hope. Scope note: this covers business-purpose renovation lending on non-owner-occupied property, the territory mapped in /blog/fix-and-flip-financing-guide.

What an ARV appraisal actually is

An ARV appraisal is an opinion of market value subject to a hypothetical condition: that the renovation described in your scope of work has been completed. The appraiser is typically engaged to produce two values — the as-is value of the property today, and the as-repaired value assuming completion — reported on standard residential forms with a subject-to-completion condition. The critical input is your scope of work and budget. The appraiser is not valuing what you might do to the property; they are valuing the property assuming you do exactly what the documents describe. A vague scope produces a defensive appraisal, and a scope that changes later invalidates the premise the number was built on.

Where the number comes from

The engine is comparable sales: recently sold properties, near the subject, renovated to a standard comparable to your planned scope. The appraiser adjusts for differences — living area, bed and bath count, lot, condition, and the rest — and reconciles the adjusted sales to a value opinion.

Two market realities constrain the output. The first is the neighborhood ceiling. Markets pay for a renovated house up to roughly what renovated houses in that location sell for, and scope beyond that standard returns less than it costs; an appraiser who cannot find closed sales supporting your intended finish level in that location will not invent them. The second is that changes to utility — added bedrooms, added bathrooms, added square footage — move value differently than finish quality does, and the comps decide how much. Neither of these is appraiser conservatism. Both are how the exit market actually behaves, which is why the appraisal is information about your eventual sale, not just an obstacle in your loan file.

Timing shades everything. Comparable sales are historical by definition, while the ARV is an opinion about a sale that will happen months from now, after your renovation. In moving markets that gap matters in both directions, and appraisers handle it with market-condition adjustments that are themselves judgment calls. Seller concessions buried in comp prices, a comp that closed before a rate move, a thin quarter that produced only two usable sales — all of it lands in the reconciliation. None of this makes the number arbitrary; it makes the number an argument built from evidence, which is exactly why the strongest challenge to it is better evidence rather than louder conviction.

How lenders use the number

Renovation lenders commonly size loans to the lesser of two caps: a percentage of ARV, and a percentage of total cost — purchase price plus renovation budget. The cost cap exists precisely because ARV is an opinion; it keeps the loan tethered to money actually going into the project. Many lenders also cap the initial advance against the purchase price separately from the renovation holdback, and the holdback itself is disbursed through draws with their own mechanics and fees, part of the short-term cost stack detailed in /blog/hard-money-vs-bridge-loans.

Between the appraisal and the loan sits review. Lenders commonly run internal valuation review or order review products, and cuts happen — an ARV trimmed in review resizes the loan late in the process, when your deposit and timeline are already committed. Budgets get reviewed for feasibility too: a scope priced implausibly low invites either skepticism about the ARV's premise or a demand to document the numbers. The same subject-to-completion logic extends to ground-up lending, where the future-value appraisal described in /blog/construction-loans-for-investors plays the equivalent role.

What moves ARV and what does not

Material scope changes move it, in both directions, and commonly require an updated appraisal — which costs time mid-project and can resize a loan you have already drawn against. Legal status moves it: permits matter, and unpermitted space is commonly excluded from the value or discounted. Your finish selections beyond the neighborhood standard largely do not move it, whatever they cost you. And the purchase price does not move it at all. ARV is independent of what you paid, which is exactly why lenders anchor to it instead of to your contract.

Challenging a low ARV

A reconsideration of value is the formal channel, and it runs on evidence: specific closed sales the appraiser did not use, with stated reasons they are comparable, or factual errors in the report — wrong square footage, a comp whose renovation the appraiser missed. It does not run on your pro forma. Success is real but modest, so go in with sales, not sentiment. If the reconsideration fails and the number still will not carry the deal, the remaining choices are more capital, a renegotiated purchase price, or walking away — and it is worth remembering that the appraiser's opinion is a forecast of the same market your exit depends on. An ARV you have to fight for is a thin exit margin wearing a loan-sizing costume.

Common mistakes

• Back-solving ARV from the loan you want, or lifting it from a wholesaler's marketing sheet.
• Supporting ARV with active listings and pending sales rather than closed sales.
• Planning to the ARV cap and ignoring the cost cap, then discovering the loan sizes to the smaller number.
• Changing scope mid-project without telling the lender, then failing draw inspections that check work against the original documents.
• Renovating past the neighborhood ceiling and expecting the appraisal to fund the difference.
• Treating the appraisal purely as an obstacle rather than a free second opinion on your exit price.

How to verify

• Ask the lender which values will be ordered, on which forms, whether internal review can adjust them, and at what point in the process the number becomes final.
• Get the sizing formula in writing: the ARV percentage cap, the cost percentage cap, the lesser-of language, and the initial-advance rule.
• Deliver a complete, itemized scope of work and budget to the appraiser, and keep the executed version fixed for the life of the loan.
• Pull your own closed, renovated comps before you go under contract, and compare them honestly to the standard you actually plan to build.
• Ask how a reconsideration of value works — evidence requirements and turnaround — before you need one.
• If scope changes mid-project, ask the lender what that does to the appraisal premise and the draw schedule before you build the change, not after.
