What Happens When the Appraisal Comes in Below Zillow’s Suggested Price?


One of the biggest misconceptions in real estate is that a Zillow estimate determines what a home is worth in the eyes of a lender. While Zillow can provide a helpful starting point, lenders base their loan decisions on the property’s official appraisal, not an online estimate.

If your home doesn’t appraise at the Zillow-suggested price, the buyer may run into financing challenges because the lender typically won’t lend more than the appraised value. In other words, if a buyer agreed to pay $500,000 but the home appraises for $475,000, the lender will usually calculate the loan based on the $475,000 appraisal.

At that point, several outcomes are possible:

  • The buyer can make up the difference in cash. If they have the funds available, they may choose to cover the appraisal gap themselves.
  • The buyer and seller can renegotiate the purchase price. Many transactions move forward when both parties agree on a revised price closer to the appraised value.
  • The seller can challenge the appraisal. If there are factual errors or comparable sales that were overlooked, there may be grounds for a reconsideration.
  • The deal may fall through. If the buyer cannot secure financing and neither side can bridge the gap, the contract could be terminated, depending on the financing and appraisal contingencies.

It’s also worth remembering that Zillow’s estimates are generated by algorithms and broad market data. An appraisal involves a licensed professional evaluating the home’s condition, features, location, and recent comparable sales. That’s why a Zillow estimate and an appraisal can sometimes differ significantly.

For sellers, the key takeaway is not to view a low appraisal as a reflection of your home’s overall value. It simply means the appraiser’s opinion of market value came in lower than the contract price. For buyers, it’s a reminder that loan approval often depends as much on the property’s appraised value as it does on personal financial qualifications.

The good news is that a low appraisal doesn’t automatically kill a deal. In many cases, buyers and sellers work together to find a solution that keeps the transaction moving toward a successful closing.
