Can You Challenge an Appraisal? Grounds, Evidence, and ROV

To challenge a home appraisal, you file a reconsideration of value (ROV) with your lender, backed by evidence of factual errors in the report or stronger comparable sales than the ones the appraiser used. Federal law entitles you to a free copy of the appraisal, generally at least three business days before closing, so you have time to review it and act.¹ A challenge succeeds when you can point to something objectively wrong. It fails when you just disagree with the number.

Get the Report and Read It Carefully

You can’t challenge what you haven’t seen. Under Regulation B, which implements the Equal Credit Opportunity Act, your lender must send you a copy of every appraisal and written valuation prepared for your loan. For first-lien mortgages, delivery has to happen promptly on completion or at least three business days before closing, whichever comes first.¹ You can waive the three-day window, but you don’t have to. If the loan falls apart, the lender still owes you the report within 30 days of deciding the deal won’t close.

There’s no extra charge for this copy. The right applies whether you were approved or denied, and whether you close or not.² Once you have it, read it line by line. Many successful challenges start with a plain factual mistake the appraiser would have fixed if anyone had flagged it.

What Counts as a Valid Reason to Challenge

Appraisers hear “my house is worth more” all the time. What moves the number is showing them where the data in their own report is wrong. Sentimental value, money spent on the property, Zillow estimates, and a neighbor’s opinion aren’t going to do it.

These are the grounds that actually work:

Errors in physical characteristics such as wrong square footage, a miscounted bedroom or bathroom, or an incorrect lot size. These flow directly into the comparison math.
Omitted improvements like a finished basement, a full kitchen renovation, or a newer HVAC system. Permanent upgrades that add livable space or clear functional value belong in the report.
Poor comparable selection, where the appraiser pulled sales from a different school district, a different market, or across a boundary like a highway that separates two distinct areas. Most real value disputes live here.
Outdated or distant comparables — sales that closed many months earlier or homes far enough away to reflect different local conditions.
Site-specific features the report ignored, such as commercial-use zoning, waterfront access, or an unusually large lot compared to the comps chosen.

Building the Evidence for a Reconsideration of Value

An ROV request succeeds on the quality of what you attach. The strongest submissions include alternative comparable sales that match your property more closely than the appraiser’s picks. For every suggested comp, give the full street address, sale date, closing price, and gross living area at a minimum. If it hit the MLS, attach the listing.

Document any factual errors with independent proof. If the report shows 1,800 square feet and your home measures 2,100, include the building permit, tax records, or a professional measurement. If the finished basement was ignored, attach photos and any contractor invoices. Give the appraiser data they can verify, not arguments about what the property “should” be worth.

There’s no universal ROV template. The 2024 interagency guidance takes a principles-based approach and leaves each lender to design its own submission process and decide what evidence it will accept.³ Your lender may require three comps or five, may cap the radius or the age of the sales, or may accept broader market data. Ask your loan officer for the specific form and instructions before you start pulling records.

Submitting the Request and What Happens Next

In almost every transaction, the ROV goes to your loan officer or lender, not straight to the appraiser. You may hear that federal law forbids contact between borrowers and appraisers. That’s a misreading. The appraiser independence statute prohibits pressuring an appraiser toward a target value, but it explicitly allows consumers and other parties to ask the appraiser to consider additional information, provide further explanation, or correct errors.⁴ Even so, most lenders route these requests through their own channels or through an appraisal management company, so plan on working through your loan officer.

Keep the tone factual. Explain what’s incorrect, point to your evidence, and let the data carry the argument. An aggressive request doesn’t move faster and gives the appraiser less reason to engage seriously with your comps.

Once the lender receives your submission, it goes to the original appraiser or an appraisal management company. The appraiser reviews your alternative comparables and supporting data, then either issues a revised report with an updated value or provides a written explanation for why the original stands. Expect at least several business days, longer if the appraiser has to verify your comps independently. There’s no guarantee the value moves. A home that sold for more but has an extra bedroom and a bigger lot isn’t automatically a better comp just because it’s nearby.

When You Can Get a Second Appraisal

If the ROV doesn’t fix the problem, a second appraisal is sometimes available. Conventional lender policies vary, and most require evidence that the first appraisal was fundamentally flawed before ordering a new one.

Government-backed loans have their own rules. Under HUD Handbook 4000.1 for FHA loans, the lender may order a new appraisal if the original is deficient.⁵ For VA loans, no duplicate appraisal can be requested for the same borrower and property during the six-month validity of an existing Notice of Value. A veteran who initiates an ROV may elect to fund a new assessment at their own expense, but when the request comes from the lender or seller, the veteran cannot be charged.⁶

Outside those government-backed lanes, expect to pay out of pocket for a second appraisal. Residential fees typically run from a few hundred dollars for a straightforward single-family home to well over $1,000 for complex or high-value properties.

The VA Tidewater Early Warning

VA borrowers get a step that most buyers don’t. Under the Tidewater initiative, when a VA appraiser concludes the value will land below the contract price, the appraiser must notify a designated point of contact before finalizing the report.⁷ That gives your team a window to submit additional comparable sales or property information before a low value becomes official.

The appraiser can’t discuss the report’s content during this notification, only that additional information is needed. Still, the early warning matters, because assembling comps ahead of a closing deadline is much easier than doing it under one. If a VA appraisal is being ordered, make sure a point of contact with name, phone, and email is listed on the order form.

If the Value Stands: Handling the Appraisal Gap

When the challenge fails and the value stays below the purchase price, you’re dealing with an appraisal gap. Your options depend on your contract, your loan type, and how much you want the house.

Renegotiate the price. Ask the seller to drop to the appraised value. In slower markets, sellers often agree because the next buyer will likely see the same result.
Cover the gap in cash. Pay the difference on top of your down payment. Some contracts include an appraisal gap clause where you commit upfront to absorb a set dollar amount.
Split the difference. Negotiate for the seller to eat part of the gap while you cover the rest. This is often the real-world outcome when both sides want to close.
Walk away. If your contract has an appraisal contingency, you can back out with your earnest money. Without one, your deposit may be at risk.

FHA buyers get an extra layer through the FHA amendatory clause, which is required in every FHA purchase contract. If the appraisal comes in below the agreed price, the buyer can walk with the full earnest money deposit refunded, no matter what other contract terms say.

When the Problem Is Bias, Not a Bad Comp

Sometimes the issue isn’t a factual error or a weak comparable. Sometimes the valuation reflects bias tied to race, religion, national origin, sex, disability, or familial status. The Fair Housing Act makes it unlawful for anyone in the business of appraising residential property to discriminate on any of those bases.⁸

If you suspect bias, file with more than one agency:

HUD’s Fair Housing and Equal Opportunity office handles appraisal discrimination complaints.
The Consumer Financial Protection Bureau accepts complaints when a lender is alleged to have discriminated, including by relying on a biased appraisal.
Your state’s appraiser regulatory agency investigates individual appraiser conduct. The Appraisal Subcommittee’s national hotline at refermyappraisalcomplaint.asc.gov can identify which state and federal agencies have jurisdiction over your specific complaint.⁹

The hotline itself doesn’t file complaints on your behalf or judge whether one has merit. It routes you to the right agencies, and you follow up. For patterns of discriminatory conduct, the Department of Justice’s Housing and Civil Enforcement Section can bring enforcement actions based on referrals from HUD.⁹ The Fair Housing Act and the Equal Credit Opportunity Act both remain in full effect in housing-related transactions, including appraisals.¹⁰
