You accepted a strong offer. The buyer is qualified, the terms look good, and then a stranger with a clipboard walks through your house and decides whether the deal survives. That’s the buyer appraisal, and it’s the step most sellers understand least.
What it is
The buyer’s lender hires an appraiser to confirm the house is worth what the buyer agreed to pay. Banks don’t lend against optimism. If the appraised value supports the price, the loan moves forward. If it doesn’t, you’re renegotiating.
Worth understanding: the appraiser isn’t working for you or the buyer. They’re protecting the lender’s collateral, which means comparable sales carry more weight with them than anything about your house that can’t be measured.
Why this trips up San Francisco sellers
Buyers here bid aggressively. Inventory is tight in the neighborhoods people want, prices move quickly, and a bidding war can push an offer well past what recent sales support. The appraiser doesn’t see the bidding war. They see data.
The city’s housing stock complicates it further. Historic homes with renovations that vary wildly from one property to the next. Condo-heavy blocks where units differ in ways the comps don’t capture. Anything unusual is harder to value, and harder to value tends to mean valued conservatively.
How the process runs
Your buyer’s offer gets accepted and the lender orders the appraisal. A licensed appraiser visits the property, walks it, and takes notes on condition and features. Then they pull recent nearby sales in similar condition and work out where your house sits against them. A report goes to the lender with a number attached. The whole thing usually takes a week or two.
When the number comes in low
This happens more often here than sellers expect, and you have three moves.
You can drop your price to meet the appraisal, which is the cleanest path and sometimes the right one. You can ask the buyer to cover the gap in cash, which works if they have it and want the house badly enough. Or you can challenge the appraisal, submitting comparable sales the appraiser missed and requesting a reconsideration of value. Challenges succeed less often than sellers hope, but a well-built comp packet does sometimes move the number.
Which option makes sense depends on how many other buyers are waiting and how motivated yours is.
Preparing for it
Price the house honestly at the start. Most low appraisals trace back to a listing price the market never supported, and no amount of preparation fixes that.
Document your upgrades. Renovations, kitchen and bath work, efficiency improvements, with permits and receipts where you have them. Appraisers credit what they can verify, and they can’t verify what nobody shows them.
Have your agent prepare a comp packet, meaning recent sales that support your price, handed over when the appraiser arrives rather than argued about afterward. Clean the place up and make sure access is easy. None of this is dramatic, and all of it helps at the margins.

Lower the price, ask the buyer to cover the difference, or challenge the valuation with better comparable sales.

Final thoughts
A buyer appraisal is where an optimistic price meets an indifferent number. Sellers who price on evidence rather than hope tend to get through it without incident. The ones who priced on hope find out during escrow, when the options are all worse.
