How to Challenge or Appeal a Low Appraisal

A low appraisal can throw a wrench into a home sale, creating real challenges for buyers, sellers, and lenders alike. If the appraised value comes in below the agreed purchase price, it can stall financing, renegotiate deals, or even cause a transaction to fall apart entirely. But a low valuation does not automatically mean the deal is dead. Understanding how to challenge a low appraisal gives you the tools to present additional evidence, correct factual errors, and potentially secure a revised — and more accurate — valuation. Here is a step-by-step guide to help you navigate the process with confidence.

What Is a Low Appraisal and Why Does It Matter?

A home appraisal is a professional assessment of a property's market value, typically required by mortgage lenders before approving a loan. When the appraised value falls below the agreed purchase price, it is considered a "low appraisal." This creates a problem because lenders will generally only finance up to the appraised value of the home, leaving a gap that must be addressed before closing.

For buyers, a low appraisal may mean they need to bring extra cash to the table to cover the difference, or renegotiate the purchase price with the seller. For sellers, it can mean accepting less than expected or risking the deal falling through. That is why knowing how to dispute or appeal a low appraisal is a valuable skill for anyone involved in a real estate transaction.

Step 1: Review the Appraisal Report Carefully

The first step in challenging a low appraisal is to obtain a copy of the full appraisal report. Buyers have a legal right to receive a copy of the appraisal they paid for. Once you have it in hand, read through every section carefully with an eye for the following issues:

Factual errors: Check that the square footage, number of bedrooms and bathrooms, lot size, and other property details are accurate. Even small mistakes can meaningfully affect the final valuation.
Missed features or upgrades: Did the appraiser overlook a recently renovated kitchen, a finished basement, or a newly installed roof? Features that add value should be reflected in the report.
Incorrect comparable sales: Appraisers use comparable sales — often called "comps" — to establish market value. Review which properties were selected and whether they are truly similar to the subject property in terms of size, condition, location, and age.

Documenting specific errors or omissions is essential before moving forward. Vague dissatisfaction with the number is not sufficient grounds for a successful appeal — you need concrete, factual evidence to support your challenge.

Step 2: Gather Supporting Evidence

Once you have identified potential issues with the report, begin compiling evidence that supports a higher valuation. Strong evidence packages typically include:

Recent comparable sales: Research recent sales of similar properties in the immediate area that the appraiser may not have considered. Focus on homes sold within the past 90 days and within close geographic proximity.
Documentation of upgrades: Collect permits, contractor invoices, and photos of any improvements made to the property, particularly those completed within the last few years.
A detailed list of corrections: Create a written summary of every factual error you found in the report, along with documentation supporting the correct information.
Market trend data: If home prices in the area have been rising rapidly, data showing upward market trends can help demonstrate that the appraiser's comps may already be outdated.

Organize all of this material clearly and professionally. The goal is to make it as easy as possible for the appraiser or review board to understand your position.

Step 3: Request a Reconsideration of Value (ROV)

A Reconsideration of Value, commonly abbreviated as ROV, is a formal request submitted to the appraiser — typically through the lender — asking them to revisit their assessment in light of new information or corrections. This is the most common and often most effective first step in the appeals process.

Your ROV should be respectful, factual, and well-organized. Avoid emotional language or simply arguing that the value "should be higher." Instead, focus on specific, documentable issues: factual errors in the report, overlooked property features, or better comparable sales that were not considered. Submit all supporting evidence along with the formal request, and allow the appraiser adequate time to respond.

Step 4: Request a Second Appraisal

If the ROV does not result in a satisfactory revision, another option is to request a second appraisal. In some cases, lenders will order a review appraisal or a desk review, where a second licensed appraiser evaluates the original report for accuracy and methodology. Alternatively, a buyer or seller may pay out-of-pocket for a completely independent appraisal from a different certified professional.

Keep in mind that lenders are not always obligated to accept a second appraisal, but having one in hand can strengthen your negotiating position and may open the door to further discussions. It can also be particularly useful if the first appraisal contained significant errors or appeared to reflect a lack of local market knowledge.

Step 5: Renegotiate the Purchase Price

If the appraisal challenge does not succeed, renegotiation is often the most practical path forward. Buyers can use the low appraisal as leverage to ask the seller to reduce the purchase price to match the appraised value. Sellers, on the other hand, may be unwilling to drop the price if they believe the appraisal undervalued the home.

Both parties can also agree to split the difference — with the buyer bringing additional funds to closing and the seller reducing the price slightly — to bridge the gap and keep the deal alive. The right solution will depend on how motivated each party is to close and what the current market conditions look like in your area.

Step 6: Walk Away If Necessary

In some situations, the best option is to walk away. Most purchase agreements include an appraisal contingency that allows buyers to exit the transaction without penalty if the home appraises below the purchase price. Before making this decision, consult with your real estate agent and review your contract carefully to understand your options and any applicable deadlines.

Final Thoughts

A low appraisal is frustrating, but it is not always the final word. By reviewing the report closely, gathering solid evidence, submitting a formal reconsideration of value, and exploring all available options, you can take meaningful steps to protect your interests and keep your transaction on track. Working closely with an experienced real estate agent and your lender throughout this process is key — their expertise and relationships can make a significant difference in how quickly and smoothly your challenge is resolved.
