How to Contest an Appraisal With a Reconsideration of Value

To contest an appraisal with a reconsideration of value, you submit a written request to your lender that identifies specific factual errors in the report, points to better comparable sales the appraiser missed, or documents property features that were overlooked. Federal law protects your right to ask the appraiser to consider additional comparables, provide further explanation, or correct mistakes.¹ The strength of your challenge depends on evidence, not opinion. If the reconsideration fails, a second appraisal, a renegotiation, or a regulatory complaint may still be on the table.

Get the Full Appraisal Report First

You cannot build a challenge without the document. Federal law requires your lender to give you a copy of the appraisal promptly after it is completed or at least three business days before closing, whichever comes first. You can waive the three-day window, but only if you do so at least three business days before closing. The lender also must notify you of this right within three business days of receiving your loan application.²

The lender cannot charge you extra for the copy itself. A reasonable fee for the appraisal is allowed, but not for photocopying, postage, or delivery of your copy.² If your loan officer is slow to send it, cite that regulation. Read the whole thing, especially the comparable sales the appraiser chose and the adjustments applied to each one.

What Counts as a Legitimate Reason to Challenge

Fannie Mae’s guidelines set the bar plainly: any request for a value change must be based on material and substantive issues, not simply the fact that the appraisal doesn’t support your loan amount.³ “I think my house is worth more” is not a case. You need specific factual errors, overlooked features, or better comparable sales.

Factual Errors in the Report

Start with the basics: square footage, bedroom and bathroom counts, lot size, and year built. Appraisers sometimes rely on outdated public records, and a wrong square footage figure alone can shift a valuation by tens of thousands of dollars. If you finished a basement, added a bathroom, or enclosed a porch, verify the report reflects those improvements. Building permits and contractor invoices are the strongest proof because they show both the scope and the date of the work.

A caution that catches homeowners off guard: unpermitted improvements can hurt you. Appraisers may exclude unpermitted additions from the valuation entirely, so that square footage won’t count in your favor even if the work is high quality.

Better Comparable Sales

The comparable sales section is where most successful challenges are built. The appraiser chose specific recently sold homes to benchmark yours, and if those matches were poor, the value conclusion suffers. Fannie Mae requires appraisers to report twelve months of comparable sales history.⁴ More recent and closer sales generally carry more weight.

Look for sales the appraiser missed that better match your home’s condition, style, size, and location. If a dated fixer-upper was used to value your fully renovated home, find two or three recently sold renovated homes in the same area. Your real estate agent can pull this data from the MLS, and federal interagency guidance specifically recognizes that parties to the transaction may provide comparable properties and other relevant market data for the appraiser to consider.⁵ For each comparable you propose, include the address, sale price, sale date, and a brief note on why it is a better match than what the appraiser used.

External Factors

Sometimes the issue is not your house but the appraiser’s read of its surroundings. Proximity to a highway, commercial zoning, or environmental concerns can trigger negative adjustments. If the appraiser applied one that doesn’t actually affect your property, or overstated its impact, document why. Recent nearby sales at strong prices can show that the market isn’t penalizing your location the way the report assumes.

How to Submit the ROV Request

There is no universal ROV form. Each lender creates its own process and documentation requirements.⁶ Since May 2024, Fannie Mae has required lenders to maintain standardized policies for handling borrower-initiated ROV requests, formalizing the right of borrowers to appeal an appraisal on their own behalf.⁷ Ask your loan officer for the specific submission process. Your package should list the errors you identified, the addresses and sale prices of your suggested comparables, and supporting documentation like permits, photos, or floor plans.

You submit to your loan officer, not directly to the appraiser. The lender forwards the request to an appraisal management company, which acts as a neutral intermediary. Federal law prohibits anyone with an interest in the transaction from coercing or influencing an appraiser’s judgment, and the AMC exists to maintain that separation.¹ The AMC checks that your submission contains legitimate data before passing it to the original appraiser.

The appraiser then issues one of two responses: a revised report with an updated value and a new signature, or a written explanation of why the original value stands. Processing typically takes several business days. A vague complaint that the value is too low gets dismissed. Three well-chosen comparable sales with clear explanations of why they are superior matches give the appraiser a reason to reconsider. The appraiser’s response is final within the ROV process.

FHA and VA Loans Follow Different Rules

If your loan is backed by the FHA or VA, additional protections apply that don’t exist for conventional mortgages.

VA Loans and the Tidewater Procedure

VA loans include a built-in early warning system. Under the Tidewater procedure, when a VA appraiser determines the value will come in below the contract price, they must notify the lender by phone or email before completing the report.⁸ The appraiser provides a preliminary value opinion, and the parties then have two business days to submit additional sales data.⁵ You can influence the outcome before the report is finalized rather than fighting it afterward.

If Tidewater doesn’t close the gap, VA borrowers can ask their lender to contact the VA to request a formal reconsideration of value. Renegotiating the sales price or paying the difference in cash remain the fallback options.

FHA Loans and Second Appraisals

FHA has stricter rules on second appraisals. One can be ordered only when the lender’s underwriter finds the first appraisal has a material deficiency and the original appraiser is unable or unwilling to resolve it. Material deficiencies are problems that directly affect the value conclusion or marketability, or that indicate potential violations of fair housing laws.⁹ A low number alone doesn’t qualify.

One important distinction from conventional loans: for FHA second appraisals, the lender pays the cost, not the borrower.⁹ The lender must document the deficiency in the mortgage file before ordering a replacement. When the deficiency is severe, such as evidence of bias or a failed inspection, the underwriter can skip communicating with the original appraiser and order a new report.

When a Second Appraisal Is Possible on a Conventional Loan

On a conventional mortgage, a lender may allow a new appraisal when the original is technically or legally insufficient and an ROV can’t fix the underlying problems. That usually means the original appraiser lacked qualification for the property type, failed to inspect properly, or produced a report with systemic errors rather than isolated mistakes. The lender selects the new appraiser through the standard AMC process to maintain independence.¹⁰ On conventional loans, the borrower typically pays. A standard single-family appraisal generally runs in the $300 to $425 range. The second report becomes the primary underwriting document and effectively replaces the first.

Options if the Value Won’t Move

Sometimes the appraisal is accurate and the home is not worth the contract price. If your ROV fails and a second appraisal isn’t warranted, three paths remain:

Renegotiate with the seller to lower the price to match the appraised value.
Cover the gap in cash at closing, bringing the shortfall on top of your down payment. Some buyers negotiate a split with the seller.
Walk away. If your contract has an appraisal contingency, you can terminate and recover your earnest money. Without one, walking away typically means forfeiting the deposit.

If You Suspect Bias in the Appraisal

A low appraisal caused by racial or neighborhood bias is illegal. The Fair Housing Act prohibits discrimination in property valuations, and federal regulators have documented cases of appraisers injecting race, ethnicity, and national origin into reports where those factors have no place.

The Federal Housing Finance Agency has identified red flags including references to the racial or ethnic composition of a neighborhood, the languages spoken in an area, the foreign birthplaces of residents, and amenities geared toward a particular religious or ethnic group. FHFA found appraisers describing neighborhoods with phrases like “highly diverse ethnically,” noting shifts in racial demographics to explain value trends, and attributing rising prices to “gentrification.”¹¹ None of that belongs in an appraisal.

If you see this kind of language in your report, HUD’s Office of Fair Housing and Equal Opportunity accepts housing discrimination complaints online or by phone at 1-800-669-9777. You can also complain to the Consumer Financial Protection Bureau if you believe the lender used an improper appraisal. The Appraisal Subcommittee’s national complaint hotline will direct you to the correct state or federal agency for your situation.¹² FHA’s updated policy explicitly treats potential fair housing violations as a material deficiency that can justify a second appraisal.⁹

Filing a Complaint With Your State Appraiser Board

If an appraiser violated professional standards but your concern doesn’t rise to discrimination, the state appraiser regulatory board handles complaints about failures to follow the Uniform Standards of Professional Appraisal Practice. USPAP prohibits appraisers from accepting assignments with predetermined value conclusions and requires independent, impartial judgment.¹³

A strong complaint includes a copy of the appraisal report and specific examples of how the appraiser fell short. Point to concrete problems: comparable sales that were obviously inappropriate, adjustments that defy market data, property features that were misreported, or an inspection that clearly did not happen. The Appraisal Subcommittee’s national hotline can help identify which state or federal agency should receive your complaint.¹⁴

State boards conduct an initial review and may open a full investigation. Consequences for an appraiser range from mandatory remedial education to license suspension. These boards cannot change the value on your individual appraisal, but a board finding against the appraiser can influence your lender’s willingness to discard the report and order a replacement. The process takes months, so it won’t rescue a transaction on a tight closing deadline.
