You can appeal a home appraisal through a formal process called a Reconsideration of Value, or ROV. Federal rules let your lender ask the appraiser to review new evidence, consider better comparable sales, or correct outright mistakes in the report. The request always goes through your lender, never directly to the appraiser, and in most loan programs it costs nothing. If the ROV doesn’t move the number, you still have options: a second appraisal, renegotiating the price, bringing cash to close the gap, or walking away if your contract protects you.
Get the Appraisal Report First
You cannot challenge what you haven’t read. Federal law requires your lender to give you a copy of every appraisal and written valuation tied to your loan application. Under Regulation B, the lender must deliver the report promptly after it’s completed or at least three business days before closing, whichever comes first.1Consumer Financial Protection Bureau. 12 CFR 1002.14 Rules on Providing Appraisals and Other Valuations You can waive the three-day window in writing to close faster, but the lender cannot refuse to hand over the report.
If you applied for a first-lien mortgage, your lender also has to send you a written notice within three business days of receiving your application explaining your right to receive appraisal copies.1Consumer Financial Protection Bureau. 12 CFR 1002.14 Rules on Providing Appraisals and Other Valuations If the deal falls apart and you waived the delivery deadline, the lender still must send the report within 30 days of deciding the loan won’t close. The appraisal is the document you will build your appeal around, so don’t accept being told it’s internal.
What You Can Actually Appeal
Regulation Z, which implements the Truth in Lending Act, prohibits anyone from pressuring, bribing, or threatening an appraiser into hitting a target number. The same rule explicitly permits asking an appraiser to consider additional property information, review comparable sales data, or correct errors.2eCFR. 12 CFR 1026.42 Valuation Independence That line between influencing a value and asking for a legitimate review is the legal basis for every ROV.
In 2024, five federal agencies issued joint guidance formalizing how lenders should handle ROV requests. The guidance defines an ROV as a request from the lender to the appraiser to reassess the report based on deficiencies or new information that could affect the value, and it tells lenders not to build processes that put unreasonable barriers in a consumer’s way.3Office of the Comptroller of the Currency. Interagency Guidance on Reconsiderations of Value of Residential Real Estate Valuations
Factual Errors About the Property
The clearest ROV argument is that the appraiser got something objective wrong. Three bedrooms listed when you have four. 1,800 square feet reported when the home actually measures 2,100. Wrong lot size, wrong zoning, a garage or finished basement left out of the description. These mistakes happen more often than you’d expect, often because the appraiser leaned on outdated public records or tax assessor data.
Square footage disputes have a specific standard behind them. Fannie Mae requires appraisers to follow ANSI Z765-2021 when measuring and reporting living area on appraisals that include interior and exterior inspections.4Fannie Mae. Standardizing Property Measuring Guidelines Finished areas must have ceilings of at least seven feet, below-grade space is reported as below-grade regardless of finish quality, and two-story foyers can’t be double-counted. If the appraiser’s measurements don’t match the standard, you have a concrete discrepancy to raise.
Weak or Wrong Comparable Sales
Most ROV disputes come down to comparables. Fannie Mae’s guidelines say comparable sales that closed within the last 12 months should be used, though the best comps aren’t always the most recent.5Fannie Mae. Comparable Sales There is no federal rule setting a maximum distance. The VA, for example, has no minimum or maximum distance requirement at all, noting that in suburban or rural areas suitable comparables may be many miles away.6Veterans Benefits Administration. Circular 26-17-14 – Clarification of Locational Requirements of Comparable Sale Properties for VA Appraisals
What matters is whether the comps genuinely reflect your market. Sales from a neighborhood with different school zones, significantly smaller lots, or inferior condition are worth challenging. So are foreclosures or short sales used to value a non-distressed home, since those transactions rarely reflect open-market value. Your ROV should propose specific better comparables and explain exactly why each one fits your property more accurately than what the appraiser chose.
The Evidence You’ll Need
A successful appeal depends on what you submit. Objections that the home is “worth more” without data go nowhere.
For comparable sales disputes, the 2024 interagency guidance recommends providing the street address, sale price, date of sale, gross living area, and a listing copy if the property was listed, along with any other detail that helps the appraiser evaluate the comp.7Federal Register. Interagency Guidance on Reconsiderations of Value of Residential Real Estate Valuations Stick to sales that closed before the effective date of the appraisal. A real estate agent with MLS access is usually the best resource, since they can pull detailed records and filter by features that match your home.
For factual errors, bring documentation the appraiser can verify. A professional survey or floor plan showing correct square footage. The zoning classification pulled from your local planning office. Photos of rooms or features that were missed or miscategorized. If you’ve renovated, gather building permits, contractor invoices, and before-and-after photos. An appraiser reviewing an ROV wants records, not opinions about what a kitchen remodel was worth.
How to Submit the Appeal
You cannot contact the appraiser yourself. Regulation Z prohibits anyone involved in the transaction from attempting to influence an appraiser’s independent judgment through coercion, inducement, or instruction.2eCFR. 12 CFR 1026.42 Valuation Independence Every communication goes through your lender or the Appraisal Management Company it uses. Your loan officer passes your ROV package to the lender’s internal appraisal or quality control team, which decides whether to forward it to the appraiser.
If the lender’s team finds your evidence credible, they send it on. The appraiser then reviews the new data and either revises the report with an updated value or writes a detailed explanation of why they’re standing by the original number. Both outcomes are legitimate. An appraiser with solid reasoning for keeping the original value isn’t violating anything by declining to change it.
Turnaround varies by lender, but the internal review plus appraiser response usually takes at least several business days. If you’re under contract with a closing date approaching, raise the ROV the moment you spot a problem. Waiting even a few days can put your timeline at risk.
FHA Loans Have Their Own Rules
If you’re using an FHA-insured mortgage, your lender must follow specific ROV rules that took effect in September 2024. HUD Mortgagee Letter 2024-07 requires every participating lender to establish a borrower-initiated ROV process and disclose it to you both at loan application and when they deliver the appraisal.8HUD. Mortgagee Letter 2024-07 Appraisal Review and Reconsideration of Value Updates The disclosure has to explain how to submit the request, what to include, and how long the review takes.
Under FHA rules, your ROV can include up to five alternative comparable sales, and the lender cannot charge you for processing the request.8HUD. Mortgagee Letter 2024-07 Appraisal Review and Reconsideration of Value Updates You get one borrower-initiated ROV per appraisal, so gather everything before you submit. The lender must acknowledge receipt in writing, provide status updates, and deliver the results in writing. If your initial request is incomplete, the lender has to work with you to fix it rather than reject it outright.
VA Loans and the Tidewater Procedure
VA-backed loans have an early-warning step called Tidewater. When a VA fee appraiser concludes the property will likely appraise below the purchase price, they must notify a designated point of contact before finalizing the report.9Veterans Benefits Administration. Circular 26-17-18 – Procedures for Improving Communication with Fee Appraisers in Regards to the Tidewater Process That contact, usually the loan officer or real estate agent, then has two working days to submit additional comparable sales or supporting data.
The additional information should follow a format similar to the comparable sales grid on a standard appraisal form. Any comp you submit must be a verified closed sale, and pending contracts need all addendums attached along with a narrative comparing the pending sale to your property.9Veterans Benefits Administration. Circular 26-17-18 – Procedures for Improving Communication with Fee Appraisers in Regards to the Tidewater Process If the new data doesn’t change the appraiser’s opinion, the final report includes an addendum explaining what was submitted and why it wasn’t persuasive. Two days is tight. Your agent should be ready to pull comparables the moment Tidewater is triggered.
If the Value Still Doesn’t Change
Sometimes the appraiser reviews everything and holds the number. The lender can then order a second appraisal with a different appraiser conducting an independent evaluation. The borrower typically pays for it, and residential appraisal fees generally run from a few hundred to over a thousand dollars depending on property type and location. The lender uses whichever report it finds most accurate for underwriting.
If the value still falls short of the purchase price, your practical options depend on the contract:
- Ask the seller to lower the price to match the appraised value. In a softer market, sellers often come down rather than start over with a new buyer.
- Cover the gap in cash. On a $300,000 contract with a $290,000 appraisal, you can bring the extra $10,000 to closing as additional down payment. The lender sizes the loan to the appraised value, so the difference comes out of pocket.
- Split the difference. The seller reduces the price, you bring some extra cash. This is probably the most common resolution in practice.
- Walk away. If your purchase contract includes an appraisal contingency, you can terminate the deal and get your earnest money back when the appraisal falls short. Without that contingency, walking away could cost you the deposit.
The appraisal contingency is the key protection. It typically gives you a specific window to terminate after a low appraisal. If you waived it to make your offer more competitive, that exit ramp is gone, which makes the ROV even more important to get right the first time.
When the Issue May Be Bias
The Fair Housing Act makes it unlawful for anyone in the business of appraising residential property to let race, color, religion, sex, disability, familial status, or national origin influence the valuation. An appraisal can also violate fair housing rules on a disparate impact basis, meaning the practice produced a discriminatory effect on a protected group even without intentional bias.10eCFR. 24 CFR Part 100 – Discriminatory Conduct Under the Fair Housing Act
The 2024 interagency ROV guidance was issued partly in response to documented patterns of appraisal bias in minority communities. The guidance encourages lenders to design ROV policies that help identify and mitigate discrimination risk.3Office of the Comptroller of the Currency. Interagency Guidance on Reconsiderations of Value of Residential Real Estate Valuations If you believe your appraisal was shaped by the racial or ethnic composition of your neighborhood, that’s grounds for an ROV and for a formal complaint with HUD’s Office of Fair Housing and Equal Opportunity.
Filing a Regulatory Complaint
If your lender’s ROV process won’t address what you consider serious errors or misconduct, you can escalate.
For issues involving appraisal standards, such as false statements in the report, grossly negligent work, or breaches of professional conduct, the Appraisal Subcommittee runs a national hotline that refers complaints to the appropriate state and federal agencies. You can get a referral online, by email, or by calling 877-739-0096. The hotline gives you a list of one to three agencies with jurisdiction. You then file directly with those agencies.11Appraisal Complaint National Hotline. Refer My Complaint
For complaints about lender conduct or violations of appraisal independence rules, the Interagency Appraisal Complaint Form routes your complaint to the appropriate federal banking regulator for review against applicable law or policy. Regulators cannot award damages, settle fee disputes, or act as your attorney. A review could lead to enforcement action, but it won’t directly change your appraisal value.12Federal Reserve Consumer Help. Appraisal Complaint Form Introduction
If you suspect discrimination, file with HUD’s Office of Fair Housing and Equal Opportunity and with the state appraiser regulatory agency. HUD investigates fair housing violations; the state board handles professional licensing. Filing with both gives your complaint the broadest review.
