An appraisal that comes in below your contract price — or below your expectations for an estate, refinance, or tax grievance — can feel like a wall. But a low appraisal is not necessarily the final word. Depending on your situation and the basis for the low value, you may have meaningful options to challenge it, supplement it, or replace it entirely.

This guide explains what those options are, when they actually work, and what the process looks like from start to finish.

First: Understand Why the Appraisal Came In Low

Before you dispute anything, you need to understand what drove the low value. There are two fundamentally different scenarios — and they call for different responses.

Scenario 1: The Appraiser Made a Factual Error

This happens more often than people realize. An appraiser may have recorded the wrong square footage, used an incorrect bedroom or bathroom count, missed a recently completed renovation, or relied on comparable sales that don't actually reflect the subject's market position. These are factual errors — they can and should be corrected.

Scenario 2: The Market Simply Doesn't Support the Price

Sometimes a low appraisal isn't wrong — it's uncomfortable. If a buyer agreed to pay more than comparable sales in the area support, a competent appraiser will produce a value below the contract price. That's not a mistake; it's the appraisal doing its job. In these cases, disputing the appraisal is unlikely to succeed because the appraiser's methodology is sound.

Knowing which situation you're in is essential before you take any next steps.

Option 1: Request a Reconsideration of Value (ROV)

A Reconsideration of Value (ROV) is a formal written request asking the appraiser — through the lender or client — to review their analysis in light of new information you provide. This is the most common and most appropriate first step when you believe the appraisal contains factual errors or missed relevant comparable sales.

What to Include in an ROV

An effective reconsideration request is specific and evidence-based. General complaints ("the value feels too low") rarely succeed. What works:

An ROV is not an opportunity to pressure an appraiser into hitting a number. It is an opportunity to provide factual information the appraiser may not have had. That distinction matters — both ethically and practically.

How the ROV Process Works

In a lender-ordered appraisal, you typically submit the ROV request to the lender, who then forwards it to the appraisal management company (AMC) or appraiser. The appraiser reviews the new information and either updates the value, provides a written explanation of why the information doesn't change their conclusion, or — in some cases — makes a minor revision.

FNMA and Freddie Mac have updated their ROV guidance in recent years, and lenders are now required to have formal ROV policies in place. You have the right to request one.

Option 2: Provide a Rebuttal with Sales Evidence

A rebuttal is similar to an ROV but typically more detailed. Rather than simply flagging that certain sales were missed, a strong rebuttal analyzes those sales against the subject and explains why they support a higher value. This can include:

In divorce and estate contexts — where the appraisal is not ordered through a lender — this type of rebuttal can be submitted directly to the appraiser, the attorney, or the court.

Option 3: Request a Second Appraisal

If the ROV process doesn't resolve the issue, or if the first appraisal appears to have fundamental problems that can't be addressed through reconsideration, ordering a second independent appraisal is a legitimate option.

A second appraisal is particularly appropriate when:

In lender contexts, lenders are not obligated to accept a second appraisal you order independently — but it can inform your negotiations and sometimes prompts the lender to order a review appraisal of their own.

Option 4: Request a Review Appraisal

A review appraisal is a formal USPAP-compliant analysis of an existing appraisal performed by a different certified appraiser. The reviewer evaluates whether the original report's methodology, data, and conclusions are credible and compliant with professional standards.

A review appraisal carries significant weight in legal proceedings and can be requested by attorneys, lenders, or parties in estate and divorce matters. It's a more formal and rigorous process than an ROV, and the findings can be used to challenge the original appraisal in court.

What Won't Work: Common Mistakes When Disputing an Appraisal

What People TryWhy It Doesn't Work
Citing the Zillow Zestimate or online AVMAVMs are not credible evidence of value in a professional or legal context. Appraisers and lenders will not give them weight.
Arguing that you paid more or need moreAn appraisal reflects market value — what a willing buyer would pay a willing seller. Contract price and personal need are not determinative.
Citing a neighbor's sale without analysisA sale is only comparable if you can show why. Citing a higher sale without addressing differences in size, condition, and features is not persuasive.
Pressuring the appraiser to hit a numberThis is a USPAP violation and can expose the person applying pressure to legal and regulatory consequences. Appraisers are ethically required to be independent.
Filing a complaint without basisLicensing complaints require evidence of a specific USPAP violation. A value you disagree with is not, by itself, grounds for a complaint.

Disputing an Appraisal in Estate and Divorce Contexts

Estate and divorce appraisals operate differently from mortgage appraisals. There is no lender in the middle, and the parties are typically each represented by attorneys. In these situations:

In estate tax matters involving the IRS, disputes over appraised value can escalate to IRS review and, in some cases, Tax Court. This is precisely why a qualified appraisal from a credentialed professional is required — not an AVM, a broker's opinion, or an informal estimate.

When Disputing Is Worth It — and When to Accept the Value

Disputing a low appraisal is worth pursuing when there is a specific, documentable reason to believe the appraiser made an error or missed material information. It is not worth pursuing as a general strategy to push the value higher without factual basis.

The most productive disputes involve clear factual corrections: the appraiser measured the wrong square footage, missed a renovated kitchen, or chose comparable sales from a different market segment. These are correctable. In those cases, a well-constructed ROV or rebuttal with documentation frequently leads to an upward revision.

When the market data simply doesn't support the price — or when the appraiser's methodology is defensible even if you disagree with the result — accepting the value and renegotiating the transaction may be the more practical path.

Frequently Asked Questions

How long does a reconsideration of value take?

In a lender context, ROV turnaround is typically 3–7 business days, though it varies by lender and AMC. The appraiser must respond in writing to the new information provided.

Can I dispute an appraisal ordered for a tax grievance?

In that context, you are the client commissioning the appraisal, so the process is simpler — you can discuss the analysis directly with the appraiser and provide additional information before the report is finalized. If the appraisal is already filed, a second or updated appraisal may be needed.

What if the second appraisal is also lower than I expected?

That is meaningful data. Two independent appraisals reaching a similar conclusion — especially if the appraisers selected different but overlapping comparables — strongly suggests the market supports that value range. At that point, adjusting your expectations rather than pursuing further dispute is usually the right call.

Can I dispute an appraisal directly with the state licensing board?

You can file a complaint with the state appraisal board if you have evidence of a specific USPAP violation — misleading reporting, gross incompetence, or ethical breach. Value disagreement alone is not a valid basis for a licensing complaint. Boards take this distinction seriously.
