What Happens If a Refinance Appraisal Comes in Low?

Updated July 9, 2026 5 min read

Waiting on a refinance appraisal can feel like a formality right up until the number comes back lower than expected, at which point the loan-to-value math that seemed settled suddenly isn’t.

The short answer

A low appraisal on a refinance generally means the loan-to-value ratio ends up higher than planned, which can require the borrower to bring extra cash to closing, accept mortgage insurance, adjust the loan amount, dispute the appraisal, or in some cases walk away from the refinance altogether. Which option makes sense depends on how far off the appraisal is and how much flexibility the borrower has.

Why the appraisal matters so much

Refinance approval is built around the loan-to-value ratio — the size of the new loan compared with the home’s appraised value. When the appraisal comes in lower than expected, that ratio rises, which can push the loan past a lender’s maximum threshold, trigger a mortgage insurance requirement that wasn’t part of the original plan, or affect the interest rate being offered.

Options after a low appraisal

Disputing an appraisal

A dispute typically works best when there’s concrete evidence the appraiser missed — comparable sales that weren’t considered, an error in square footage, or overlooked upgrades. Lenders vary in how formal this process is; some have a structured reconsideration-of-value request, while others handle it more informally. It rarely helps to simply disagree with the number without supporting documentation.

How this connects to the rest of the refinance

A low appraisal can affect more than just loan-to-value. It can also change whether an appraisal waiver would have been possible in hindsight, whether the refinance still clears the equity threshold needed to avoid mortgage insurance, or whether a second mortgage being consolidated into the new loan still fits within the lender’s limits. Running the numbers again with the new appraised value, rather than the original estimate, is the necessary next step regardless of which option is chosen.

What to weigh

A low appraisal changes the math of a refinance, but it doesn’t automatically end it. Understanding which levers are available — cash, loan amount, insurance, or a dispute — and how each affects the total cost of the loan helps turn a frustrating surprise into a manageable adjustment.
