The Hidden Appraisal Gap Trap Buyers and Sellers Miss in Los Altos

An appraisal gap happens when a home’s appraised value comes in lower than the price a buyer agreed to pay. In a competitive market like Los Altos real estate, where buyers and sellers routinely see multiple offers and over-asking bids, this gap can quietly derail a transaction that everyone thought was already done. Knowing it exists, and knowing what drives it, puts you in a far stronger position than most people walking into a deal.
You know how it goes. You tour a home, you picture your life there, and suddenly you are willing to stretch a little further than you planned just to make sure no one else gets it. That is not a weakness. That is how most buyers and sellers end up in the same situation. But here is the part most people have not thought about yet: the lender does not see the home the way you do.
What does your offer look like from a lender’s perspective? Not from yours, not from the seller’s, but from the institution that is deciding how much money to put on the line?
What Buyers and Sellers Need To Understand First
When you make an offer on a home, your lender sends an independent appraiser to assess what the property is actually worth in the current market. That appraiser is not there to validate your excitement. According to Dustin Harris, Appraiser Coach, the appraiser’s job is to remain an unbiased third party and report what the home is worth in the current market, regardless of what decisions have been made on the price side of things.
In plain terms: they look at comparable sales, market data, and the physical condition of the home. They do not factor in how many other offers were submitted, or how much you want it.
Have you ever stopped to think about what happens when those two numbers do not match?
That gap between your contract price and the appraised value is exactly what both buyers and sellers need to prepare for in a market like this one. CoreLogic data shows that appraisal gaps have been occurring at a rising rate as home prices climb faster than the comparable sales data appraisers rely on can keep up with.
Why This Keeps Happening in Competitive Markets
Here is the dynamic at play. When supply is low and buyer demand is high, prices rise quickly. Shawn Telford, Chief Appraiser at CoreLogic, describes it this way: buyers are paying prices above listing price, higher than the market data available to appraisers can support.
The Los Altos market sits squarely in this pattern. Homes in Los Altos regularly attract offers above asking price, and when an appraiser compares those offers to recent comparable sales, the numbers sometimes tell a different story. The appraiser’s job is to protect the lender from over-lending, which means they are working from a different set of incentives than you are.
Does that make sense so far? Because this is where sellers need to pay close attention too.
If you are selling, an appraisal gap does not automatically mean your deal falls apart. It means negotiations re-open. In a strong sellers’ market, the most common outcome is that the seller asks the buyer to cover the difference in cash above the loan amount. Sellers need to know this going in, because how you handle that moment determines whether the transaction closes or collapses.
What Are Your Actual Options When a Gap Appears?
What would it mean for you if a gap appeared in your transaction and you had no idea it was coming? That surprise alone can cost you time, money, and sometimes the home itself.
Here is what buyers and sellers can do when facing an appraisal gap in the Los Altos homes for sale market:
If you are a buyer: You can pay the difference out of pocket between the appraised value and the contract price. You can negotiate with the seller to lower the price closer to the appraised value. You can walk away if the contract includes an appraisal contingency. Each of those paths has consequences. Which one fits your situation?
If you are a seller: You can accept a renegotiated price. You can ask the buyer to cover the gap in cash. You can hold firm and risk losing the buyer. Or you can order a second appraisal if you believe the first one missed something significant. Sellers need to think through these options before they are ever in the room, not during the pressure of a live negotiation.
What happens if you go into that moment unprepared? In a market moving as fast as Los Altos real estate, hesitation at the wrong moment can cost both sides the deal.
The Conversation You Should Have Before You Write an Offer
Here is something worth sitting with. If you are a buyer willing to offer significantly above asking price, have you mapped out what you would do if the appraisal comes back lower? Not theoretically. Actually mapped it out, with numbers?
If you have not, that is not a judgment. Most buyers have not. But the buyers who come out ahead are the ones who know their walk-away number, their gap-coverage limit, and their contingency plan before they fall in love with a property.
And for sellers: if your home receives an aggressive offer, the strength of that offer depends partly on whether the buyer can survive an appraisal gap. A cash buyer or a buyer with significant reserves is a very different counterpart than a buyer stretched to their limit. Can you see how that changes the way you evaluate competing offers?
What if the strongest-looking offer on paper is actually the most fragile one?
