A seller signs a contract at $425,000, then the appraisal comes back at $400,000. The buyer’s lender will only finance based on the lower figure, and suddenly there is a $25,000 gap that someone has to cover or the deal collapses. According to National Association of Realtors survey data, appraisal problems contributed to roughly 21% of delayed closings in recent years. Federal rules now give borrowers a formal right to push back through a process called a reconsideration of value, or ROV. And the most effective way to win that challenge is with better comparable sales.
Federal agencies now require lenders to accept challenges
In 2024, the Federal Housing Finance Agency directed Fannie Mae and Freddie Mac to publish standardized ROV policies. In its public announcement, the FHFA defined an ROV as a formal request to address deficiencies in an appraisal, whether that means poor comparable-sale selection, outdated data, or information the appraiser overlooked. Because Fannie Mae and Freddie Mac back the majority of conventional mortgages in the United States, any lender selling loans to either entity must now maintain a clear process for borrowers to dispute a valuation.
Banking regulators followed with their own directives. The Office of the Comptroller of the Currency released supervisory guidance adopting final interagency standards on ROVs for residential real estate. The FDIC published a parallel letter to financial institutions spelling out the specific steps banks can take when an appraisal appears flawed: resolve the issue with the original appraiser, order an independent review, or obtain a second appraisal. Those options replaced what had been, at many institutions, an ad hoc process that depended entirely on who picked up the phone.
The Consumer Financial Protection Bureau reinforced the borrower’s role. In its guidance on appraisal rights, the CFPB noted that mortgage applicants can challenge inaccurate appraisals through the ROV process and connected low valuations directly to lost equity access. An undervalued home can block a sale, a refinance, or a home-equity line of credit. The CFPB expects lender ROV processes to be nondiscriminatory and accessible, meaning banks cannot bury the option in fine print or discourage requests through procedural friction.
One important caveat: these standardized ROV requirements apply to conventional loans backed by Fannie Mae and Freddie Mac. FHA and VA loans have their own appraisal dispute processes. FHA borrowers can request a second appraisal through their lender under HUD Handbook 4000.1 guidelines, while VA borrowers can invoke the VA’s “Tidewater” procedure, which gives the borrower a chance to submit additional data before the appraiser finalizes the report. The principle is the same across loan types: borrowers have a right to present evidence, not just accept the number.
How to build an ROV request that actually works
The single most effective tool in a borrower’s ROV request is a set of comparable sales the appraiser missed or misapplied. Appraisers typically select three to six “comps” to anchor their valuation. If a homeowner can identify recent closed sales of similar size, condition, and proximity that support a higher value, those comps give the appraiser concrete data to reconsider.
A vague objection (“my house is worth more”) carries almost no weight. A spreadsheet of verified sales with addresses, closing dates, square footage, lot sizes, and sale prices does. Your real estate agent can be a critical ally here. Agents have access to MLS data and local transaction history that most homeowners cannot easily pull on their own, and experienced agents often know which comps an appraiser should have used.
Presentation matters more than most borrowers realize. For each comparable sale you submit, explain why it resembles the subject property and note where it differs from the comps the appraiser chose. If one of the appraiser’s comps backs up to a busy road, needs a new roof, or sold under distressed conditions, spell that out. If the appraiser relied on sales from eight months ago when more recent closings are available within the same subdivision, flag the timing gap.
Factual errors in the original report are another strong basis for an ROV. Appraisals sometimes misstate square footage, bedroom count, or the presence of a finished basement, accessory dwelling unit, or recent renovation. Providing building permits, contractor invoices, or MLS printouts that document improvements helps the appraiser and lender verify the record quickly.
A few practical details worth knowing:
- Cost: Filing an ROV does not typically cost anything beyond the time it takes to assemble documentation. However, if the lender orders a second full appraisal, the borrower may be responsible for that fee, which generally runs $300 to $600 depending on the market.
- Timeline: The original article noted that most ROV reviews add roughly five to ten business days to the process. That delay can matter when a purchase contract has a closing deadline, so notify your agent and the title company as soon as you file.
- Tone: The ROV process is not designed to pressure an appraiser into hitting a target number. It exists to make sure the valuation rests on accurate information and appropriate comparisons. Requests that read as adversarial tend to be less effective than those that simply present better data.
What remains unclear as the rules take hold
No federal agency has yet published data on how many ROV requests lenders have received since the policies took effect, or how often those requests result in an upward revision. Without those numbers, there is no way to measure whether the framework is changing outcomes at scale or simply formalizing a process that already existed informally at some institutions. The FHFA established the requirement but did not set reporting obligations that would generate public tracking data.
Lender compliance also varies. The interagency guidance tells bank examiners to evaluate how institutions handle ROV requests, which means noncompliance could surface during supervisory reviews. But as of May 2026, no enforcement actions tied specifically to ROV failures have been publicly disclosed. Whether a given lender has built a dedicated intake portal for comp submissions or simply routes disputes through a general customer-service email depends on the institution.
How consistently appraisers respond is another open question. The guidance emphasizes appraiser independence: no one can coerce a valuation. At the same time, appraisers are expected to review credible new information in good faith. Balancing those obligations is a judgment call, and how often appraisers revise values after reviewing borrower-submitted data is not captured in any public dataset.
If the ROV does not change the number
Sometimes the appraiser reviews every comp a borrower submits and still concludes the original valuation stands. When that happens, borrowers and sellers are not out of options, but none of the alternatives are painless:
- Renegotiate the price. The seller can lower the contract price to match the appraised value, or the buyer and seller can split the difference.
- Bring cash to close. The buyer covers the gap between the appraised value and the contract price out of pocket. This only works if the buyer has the funds and is willing to pay above what a lender considers the home worth.
- Request a second appraisal. Some lenders allow this, though the borrower typically pays for it. A second appraisal is not guaranteed to come in higher.
- Walk away. If the contract includes an appraisal contingency, the buyer can exit the deal and recover their earnest money deposit.
For refinancers, the calculus is different. There is no seller to negotiate with. If the ROV fails and the home appraises too low to support the desired loan-to-value ratio, the homeowner can wait for values to rise, reduce the loan amount, or try a different lender whose appraiser may select different comps.
How the formal ROV path changes the dynamic for sellers and refinancers
Before these rules, a low appraisal often felt final. Borrowers could ask their loan officer to relay concerns, but there was no guaranteed process and no regulatory expectation that the request would be handled systematically. That has changed. Homeowners who understand the ROV framework, gather strong comparable sales, and document factual errors now have a defined path to request a second look.
The formal structure means the request must be received, reviewed, and responded to, not ignored or quietly discouraged. For a seller staring at a $25,000 appraisal gap, or a homeowner trying to refinance out of a high-rate mortgage, assembling the right comps and filing that request is one of the few moves that costs nothing and can change the outcome.
