How to Challenge a Low Home Appraisal (Reconsideration of Value)

Short answer: you challenge a low appraisal through a Reconsideration of Value, a formal request to the lender asking the appraiser to review specific evidence. Since October 31, 2024, Fannie Mae and Freddie Mac require lenders to accept one borrower-initiated ROV per appraisal, and FHA and VA have their own versions. An ROV succeeds when you supply better comparable sales or document factual errors about the property, not when you argue the number feels wrong.

You agreed on a price, the buyer is qualified, everything is moving, and then the appraisal comes in below the contract price. Suddenly the lender will only finance against the lower number, and the deal is at risk. It is one of the most stressful moments in a home sale, and it is more common than most sellers expect it to be at exactly the wrong time.

The good news: since late 2024 there is now a standardized, borrower-initiated way to challenge an appraisal called a Reconsideration of Value (ROV), and it works differently but reliably across conventional, FHA, and VA loans. This guide walks through how often low appraisals actually happen, what a low appraisal does to your deal, exactly how the ROV process works for each loan type in 2026, what makes an ROV succeed versus fail, and the documentation that supports your value before and after the appraiser shows up.

General information only, not legal or lending advice. Appraisal and ROV rules are set by Fannie Mae, Freddie Mac, HUD/FHA, and the VA, and are implemented by your specific lender. Work with your lender and agent on any specific situation.

How often do appraisals actually come in low?

Less often than the panic suggests, but often enough to matter. CoreLogic data cited across the industry showed roughly 8.6% of appraisals came in below the contract price as of mid-2024, down from about 10.7% the prior year as the market cooled. In other words, more than 90% of appraisals confirm or exceed the agreed price, and low appraisals land somewhere around 1 in 11 to 1 in 12 deals.

When they do happen, they bite. A National Association of Realtors survey from late 2025 attributed roughly 5% of delayed sales contracts to appraisal-related issues. So this is a low-probability, high-consequence event: unlikely on any given deal, but capable of derailing the one you are in right now.

What a low appraisal actually does to your deal

A mortgage lender will lend against the lower of the purchase price or the appraised value. If you are under contract at $365,000 and the appraisal comes in at $353,000, the lender treats $353,000 as the value for loan purposes. That gap (here, $12,000) is called the appraisal gap, and someone has to solve it. The options:

• Seller lowers the price to the appraised value. Cleanest for the buyer, most expensive for the seller.
• Buyer covers the gap in cash on top of their down payment, because the lender will not finance it. Only works if the buyer has the cash and the willingness.
• Meet in the middle. Common outcome: split the difference and the buyer brings some cash while the seller drops some price.
• Challenge the appraisal with an ROV. If the appraisal contains errors or missed better comparable sales, this is the path that can restore the value without either party giving up money.
• Walk. If the contract has an appraisal contingency, the buyer can typically terminate and recover earnest money.

The ROV is the only option on that list that fixes the actual problem rather than redistributing the pain, which is why it is worth understanding in detail.

What a Reconsideration of Value is (and is not)

A Reconsideration of Value is a formal request for the appraiser to review the appraisal in light of information they may have missed or gotten wrong. It is important to be precise about what it is not:

• It is not a second appraisal. It goes back to the same appraiser who did the original report. You are asking them to reconsider, not asking a new appraiser to start over.
• It is not an argument that the value "should be higher." Opinion without evidence goes nowhere. You must point to specific comparable sales the appraiser missed, or specific factual errors in the report.
• It is not a negotiation. The appraiser is required to maintain independence. You are supplying data and corrections, not lobbying.

In May 2024, Fannie Mae, Freddie Mac, and HUD jointly announced aligned ROV policies (implemented for applications on or after October 31, 2024) specifically to create a consistent, borrower-initiated framework and to combat appraisal bias. Before this, the process was ad hoc and varied by lender. Now there is a defined path.

The ROV process by loan type in 2026

Conventional loans (Fannie Mae and Freddie Mac)

Under Fannie Mae Selling Guide announcement SEL-2024-03 and the parallel Freddie Mac Bulletin 2024-06, lenders must give the borrower a disclosure about the ROV right to review both at application and again when the appraisal is delivered. Key features:

• The borrower may request one borrower-initiated ROV per appraisal. You get one well-prepared shot, so make it count.
• The disclosure must spell out the expected turn-time and exactly what information to submit (borrower info, subject property address, the appraiser's name, the effective date, and your supporting data).
• The lender must respond in a standardized format and document the communication and outcome in the loan file.

FHA loans

FHA's ROV policy comes from Mortgagee Letter 2024-07 (with the implementation date extended to October 31, 2024 by ML 2024-16). Two things sellers and buyers should know:

• No cost to the borrower. FHA explicitly prohibits charging the borrower for an ROV.
• The appraiser's response has to be documented in a revised appraisal logged in FHA Connection, so there is a paper trail of what changed and why. As one mortgage professional put it in a discussion of a challenged FHA appraisal, the revised report should show exactly what was revised: comp selection, bedroom count, adjustments, or a corrected data or math error.

VA loans

The VA has two distinct safety nets, and the timing matters:

• Tidewater happens before the value is finalized. If the VA appraiser believes the property will come in below the contract price, the Tidewater process notifies the lender, who then typically has about 48 hours to submit additional comparable sales or data supporting the price. This is your best and earliest chance, and it only works if your comps are ready to go the moment Tidewater is triggered.
• Reconsideration of Value happens after the Notice of Value (NOV) is issued. It goes to the VA in writing with specific comps or factual corrections. The VA generally reviews within about 5 business days, or up to around 20 if a staff appraiser needs to visit the property.

The practical lesson from VA deals: have your comparable sales assembled early. If you wait until Tidewater triggers to start pulling comps, you can miss the window.

What makes an ROV succeed

An ROV succeeds when it gives the appraiser something concrete to act on. The strongest ROVs contain one or both of the following:

1. Specific comparable sales the appraiser missed or misused

This is the core of a good ROV. Not "the value seems low," but "comparable sales A, B, and C, all within the last 90 days and within a half mile, closed at prices supporting the contract value, and here is why they are more comparable than the comps used in the report." One newer agent described writing a detailed reconsideration that agreed with one of the appraiser's comps, asked for the weaker ones to be excluded or replaced, and offered better alternatives. That is the right structure.

Note that appraisers are trained to prefer comps that are recent, geographically close, and genuinely similar in size, condition, and features. Offering a comp that is bigger, newer, or in a better location without adjusting for those differences will get rejected. The comp has to actually be comparable.

2. Factual errors in the report

Appraisers are human and reports contain mistakes. Common correctable errors:

• Wrong bedroom or bathroom count. In one challenged appraisal, an agent pulled the original builder floor plans to prove a room the appraiser had not counted was in fact a bedroom.
• Wrong gross living area (square footage). If the appraiser's GLA is smaller than the county records or a measured floor plan, that is a factual correction.
• Wrong condition or quality rating. If the report rates the home as average condition when it has been fully renovated, documentation of the renovation matters.
• Missed features. A pool, a finished basement, a garage, or an outdoor living feature not reflected in the report.
• Math or adjustment errors. Adjustments that do not add up, or that are not supported by market data.

The documentation that wins ROVs

Here is the part most sellers do not prepare for until it is too late. The evidence that supports your value, both in an ROV and handed to the appraiser up front, is documentation you should already have:

• Dated records of every improvement and its cost. A kitchen remodel, a new roof, an HVAC replacement, a bathroom renovation, new windows. The appraiser can only credit what they can see and verify. "New roof" is weak; "roof replaced March 2024, GAF Timberline HDZ, $14,200, transferable warranty" is evidence.
• Permits for the work. Permitted work is verifiable and defensible; unpermitted work is discounted or ignored.
• Contractor invoices and warranties. These establish the scope, the date, and the quality of the work.
• Your own comparable sales. Assembled before the appraisal, not scrambled together after a low number lands.
• A floor plan or measurement if you suspect the square footage is understated.

This is where sellers who kept records win and sellers who did not lose. If you can hand the appraiser (through your agent) a one-page list of every upgrade with dates, costs, and permits, you have given them the evidence to support your value before they ever write a number. If a low appraisal does come back, that same documentation is the backbone of your ROV. For what to keep and how, see What to Document Before Listing Your Home and What Goes in "The Packet".

The risk nobody warns you about: the appraiser can hold or even lower the value

An ROV is not free of downside. The appraiser reviews your submission and can conclude the original value stands. In rare cases, they revise it further in the wrong direction. In one widely discussed case, an agent challenged a $360,000 appraisal, and the appraiser came back at $353,000, citing (among other things) the home's lack of granite countertops relative to the comps. The agent felt punished for challenging.

The measured take from a mortgage professional in that same discussion: before assuming malice, get the revised appraisal and see exactly what changed. A single new negative adjustment (like countertops) driving a multi-thousand-dollar drop should be supported by market data, and if it is not, that is itself grounds to push back through the lender. But the lesson stands: an ROV should be built on genuinely strong evidence, because a weak challenge can invite a closer, less favorable second look.

The "out-of-area appraiser" pattern

A recurring observation among agents is that low appraisals disproportionately come from appraisers assigned from outside the local market, sometimes an hour or more away, who may not know neighborhood-level nuances (which streets command a premium, which backing conditions hurt value, what local buyers pay for). This is anecdotal, not a rule, and a competent appraiser can absolutely value a home outside their immediate area. But if your appraiser is from far away and the comps look off, note it, because unfamiliarity with the micro-market can show up as poor comp selection, which is exactly the kind of thing an ROV addresses. Appraiser assignment is controlled by the lender's appraisal management company, not by you, so this is a reason to build a strong, comp-based ROV rather than an argument you can make directly.

How to actually file the ROV, step by step

1. Read the appraisal carefully. Get a copy from your lender (you are entitled to it) and read every line: the comps used, the adjustments, the square footage, the bed/bath count, the condition rating.
2. Identify the specific problems. Wrong facts, missed comps, unsupported adjustments. Write them down with evidence for each.
3. Assemble your comps. Recent, close, genuinely comparable. Explain for each why it belongs and why a comp in the report should be replaced.
4. Gather your documentation. Permits, invoices, improvement dates and costs, floor plans, anything that corrects a factual error or supports value.
5. Submit through your lender in the required format. The ROV goes through the lender, not directly to the appraiser. Follow the disclosure you were given at application and appraisal delivery. Remember: one shot on conventional loans, so make it complete.
6. For VA, act at Tidewater if you can. If your lender tells you Tidewater was triggered, get your comps in within the roughly 48-hour window.

The bottom line

A low appraisal is uncommon (roughly 1 in 11 deals) but high-stakes when it lands. Since October 2024 there is a real, standardized Reconsideration of Value process across conventional, FHA, and VA loans, and it works, but only when it is built on specific missed comps and documented factual corrections rather than the argument that the value simply feels too low. The sellers who win ROVs are the ones who can produce dated records of every improvement, permits, and their own comps, ideally before the appraiser ever assigns a number. The paperwork you keep during ownership is the same paperwork that defends your price at the finish line.
