A low or inaccurate appraisal can stall a purchase or refinance, but you can challenge it through a formal reconsideration of value (ROV). This guide shows how to dispute a mortgage appraisal, from reading the report to submitting evidence and weighing your fallback options. Before you start, gather your appraisal copy, your Loan Estimate, and either your purchase contract or your current mortgage statement. Working with a soft credit pull mortgage pre-approval also means you can explore options without adding hard inquiries to your file.

Step 1: Get the Appraisal Report and Read It Line by Line
An appraisal is a licensed professional’s written opinion of a property’s market value, and your loan amount depends on it. Under the ECOA Valuations Rule (Regulation B), the creditor must give you a copy of the appraisal promptly after it is completed, or at least three business days before closing, whichever comes first. Confirm the current wording on the CFPB website. If your copy has not arrived, ask your broker for it today.
Start with facts, because they are the easiest errors to prove. Check each of these against your own records:
- Gross living area (square footage)
- Bedroom and bathroom count
- Lot size and year built
- Finished basement or attic space
- Renovations, such as a new kitchen or roof
- Garage size and type
Next, mark up the comparable sales (“comps”), which are recently sold similar homes the appraiser uses to support the value. For each one, note the sale date, distance from your property, size, condition, and the dollar adjustments applied. Those adjustments drive the final number, and a questionable one is often where a dispute begins.
Know what is disputable before you spend effort. Factual errors, overlooked upgrades, and weak or mismatched comps are valid grounds. Simply disagreeing with the number is not.
Step 2: Confirm the Appraisal Is Truly Wrong, Not Just Low
A low number is not automatically an error. If the comps are sound and the adjustments are reasonable, the report may simply reflect the market, and a dispute will likely fail. In that case, renegotiating the price (Step 6) is usually the better path.
Run a quick reasonableness test. Calculate the price per square foot for each of the appraiser’s comps, then do the same for a list of recent sales you pull yourself. If your list clusters near the appraiser’s figures, the value is probably defensible. If the appraiser’s comps sit well below comparable nearby sales, you may have a case.
Look for these common mistakes:
- Comps from outside your neighborhood when closer sales exist
- Stale sales that ignore more recent, higher closings
- Upgrades or additions that were not credited
- A different property type, such as a condo compared with a single-family home
- Comps from a different school zone that buyers value differently
Ask your real estate agent to review the report too. Agents see closed sales daily and can often spot a missing comp faster than you can.
Duane Buziak reviews the appraisal with clients before they file anything, so the request rests on specific, checkable points rather than frustration. An emotional request tends to be ignored, while an accurate one gets read.
Step 3: Build Your Evidence Package With Better Comparable Sales
Select three to five recent closed sales, ideally within the last 90 days to six months. They should be close to your property and similar in size, age, and condition. Include the address, sale price, sale date, and square footage for each, and say briefly why it is a better match than the appraiser’s choice.
Prefer closed sales to active or pending listings. An active listing shows only what a seller hopes to get, and a pending sale has no final price yet. A closed sale is a completed transaction between a real buyer and seller, which is the evidence appraisers are trained to weigh.
If the issue is overlooked improvements, document them:
- Gather receipts, invoices, and building permits.
- Add dated photos showing the finished work.
- List each upgrade with its approximate cost and completion date.
Then write a short, factual cover summary tied to specific line items, for example: “The report lists 1,850 square feet; the county record and floor plan show 2,020 square feet including the finished lower level.” Do not accuse the appraiser of bias or bad faith. Neutral language keeps the request credible.
Tip: Avoid leaning on automated online home value estimates as your main evidence. They are built from public data without anyone inspecting the property, and reviewers generally give them little weight. Use them, at most, as background.
Step 4: Submit a Reconsideration of Value Through Your Broker
In most cases the appraiser cannot take requests directly from you. Independence rules keep borrowers from influencing the valuation, so the request travels through the loan officer, broker, or the appraisal management company (AMC), the intermediary that orders and reviews many appraisals. Calling the appraiser yourself can create problems, so route it properly.
Ask your broker these questions first:
- How is the ROV submitted, and in what format does the AMC require it?
- Is there a limit on how many requests can be filed?
- Are there investor guidelines (Fannie Mae and Freddie Mac both publish ROV guidance, which has changed in recent years) that affect what is accepted?
Send everything as one organized packet. Include a clear subject line, the property address, the loan number, and a numbered list of issues, each pointing to a page or line in the report and the supporting document that answers it. One tidy packet gets reviewed faster than several scattered emails.
Set a timeline. ROV responses commonly take a few business days, but turnaround varies, so ask for an estimate. A delay can affect your closing date and rate lock, so confirm your lock expiration now.
Duane Buziak, working as a broker who can shop hundreds of lenders at one time, can route the request through the right channel and keep the rest of the file moving while the review runs. Nothing here guarantees the value will change, but a well-prepared request gives it a fair hearing.
Step 5: Understand What the Outcome Means for Your Loan Numbers
Loan-to-value (LTV) is your loan amount divided by the lower of the appraised value or purchase price. Here is a clearly hypothetical illustration. Suppose you agree to buy at $400,000 with 10% down ($40,000) and a $360,000 loan, which is 90% LTV. The home appraises at $380,000. The loan is now capped at 90% of $380,000, or $342,000, so you need $58,000 down, which is $18,000 more cash. Keeping the $360,000 loan would push LTV to about 94.7%.
The total cost worksheet
Monthly payment is more than principal and interest. This illustration uses a hypothetical 6.50% rate on a 30-year fixed loan, not a quote. For property tax, I use an illustrative $0.85 per $100 of assessed value, modeled on Henrico County’s real estate assessments page. Confirm the current rate and its as-of date there, since rates change. Insurance is a hypothetical $1,800 a year, and PMI is a hypothetical 0.50% of the loan a year.
- Appraisal supports $400,000 ($360,000 loan): principal and interest $2,275 + tax $283 ($3,400 a year on $400,000 assessed) + insurance $150 + PMI $150 = about $2,859 a month.
- Appraisal at $380,000, you bring extra cash ($342,000 loan): principal and interest $2,162 + tax $283 + insurance $150 + PMI $143 = about $2,738 a month, but with $18,000 more cash at closing.
Assessed value for taxes is separate from appraised value for the loan. The county sets assessed value for taxation on its own schedule and method, so a low appraisal does not lower your tax bill, and a high assessment does not raise your appraisal.
PMI math
Actual PMI pricing is set by the insurer and investor, so treat this as an illustration. At 90% LTV, 0.50% on $360,000 is $1,800 a year, or $150 a month. At 80% LTV ($320,000), PMI would be $0. Under the Homeowners Protection Act, you can request cancellation when your balance reaches 80% of the original value, and PMI ends automatically at 78% on the original schedule. On a $400,000 original value, that means a $320,000 request point and a $312,000 automatic point. Verify details through the CFPB’s homeownership resources.
Step 6: Compare Your Options If the Value Does Not Change
If the ROV is denied, you still have several paths. Review your contract deadlines and earnest money terms with your agent before choosing, because the appraisal contingency, the clause that lets you exit or renegotiate if the home appraises low, has an expiration date.
- Request a reconsideration of value: Cost is usually low, the timeline is a few business days (confirm), odds depend on evidence quality, and the risk is delay and a possible limit on requests.
- Renegotiate the price: Cost is nothing upfront, the timeline is days, odds depend on seller motivation and your comps, and the risk is the seller refusing.
- Bring extra cash: You pay the gap, the timeline is fast, odds are high because it is within your control, and the risk is draining your reserves.
- Order a new appraisal: You may pay again, the timeline is one to two weeks or more, odds are uncertain, and the risk is that the AMC or investor decides whether it is accepted. Do not order your own appraisal and assume it will be used.
- Exit under the contingency: Cost is minimal if you act in time, the timeline is set by your contract, odds are certain if the clause applies, and the risk is losing earnest money if you miss a deadline.
Some borrowers compare approaches as well. Direct providers such as Rocket, Movement, or Veterans United generally work within their own program sets. A broker can shop hundreds of options, which can matter if a different loan structure fits the new value better. Ask any provider the same questions about ROV handling and timelines.
Step 7: File a Complaint If You Suspect Bias or a Violation
Escalate only when the situation warrants it: evidence of discrimination, a significant factual error that was not corrected after you submitted proof, or a process violation, such as not receiving your appraisal copy as required.
Where to file, in order of fit (verify each link and process before submitting, as they change):
- The CFPB complaint portal for lending process and appraisal delivery issues
- The HUD fair housing complaint page if you believe the valuation reflects discrimination
- Your state appraiser licensing board, findable through the Appraisal Subcommittee, for concerns about the appraiser’s conduct
Document everything: dates, emails, every version of the report, and the name and role of each person you spoke with. A clear timeline makes any complaint stronger.
While you sort this out, protect your credit. A soft credit pull mortgage pre-approval from Duane Buziak, using NoTouch Credit Pull, lets you review alternatives without the hard inquiry that could affect your score.
Recheck the Numbers, Then Decide With Your Deadlines in Mind
Once you have an outcome, recheck your revised loan amount, down payment, PMI, and the full monthly total, then confirm your rate lock and contract dates with your agent. If you need to restructure, contact Better Mortgage Rates by Duane Buziak to review your options, including a no credit hit mortgage application path while you decide.
