The fifth price: what an appraisal really is, and what to do when it comes in low

A while back I wrote that your house has four prices at once: the online estimate, the city's assessed number, your number, and the one a buyer will actually pay. I mentioned there was a fifth, said it deserved its own post, and moved on.

This is that post.

The fifth price is the appraisal. It arrives after you've already agreed on a number, it's ordered by someone who isn't you, and it can quietly unmake a deal that everyone thought was finished.

It isn't a second opinion on your price

Here's the thing most people get wrong about appraisals, and it changes how you should think about the whole event.

The appraisal is not there to check whether you priced your house correctly. It's there to protect the lender. A bank about to lend $300,000 against a building wants an independent professional to confirm the building is worth roughly $300,000 — because if the loan goes bad, that building is what they're left holding.

So the appraiser doesn't work for you, or for the buyer. They work for the lender, and the question they're answering is how much should we be willing to lend against this?

That distinction matters because it tells you what an appraisal can and can't do. It can stop a bank from lending. It cannot stop a buyer from buying, and it does not mean your price was wrong.

What happens when it comes in low

Say the agreed price is $340,000 and the appraisal comes back at $325,000. The lender will size the loan off the lower number. That $15,000 gap has to come from somewhere, and there are only really four somewheres:

The buyer covers it in cash, on top of their down payment. That's the cleanest fix and the one most likely to be out of reach. This is also where an appraisal gap clause comes in — a paragraph in the offer where the buyer commits in advance to covering a shortfall up to a stated amount. In a competitive market it's one of the strongest things a buyer can put on the table, precisely because it takes this risk off the seller.

The seller reduces the price to meet the appraisal. Cleanest for the buyer, and the harder ask in a market this tight.

You split it, which is where most of these land.

Or the deal dies, and the house goes back on the market — now with a known appraisal problem attached to it.

Which of those four you land on depends almost entirely on what your contract already said. An appraisal contingency lets a buyer walk with their deposit intact. A gap clause, discussed above, commits them to a number instead. Both get decided when the offer is written, not when the appraisal lands — which is exactly why the boring paragraphs matter, and why they're worth thinking through months before anyone is looking at houses. The rest of those terms turn up in the first-time buyer's playbook.

The appeal almost nobody uses

Here's the part worth the whole post.

If you have a factual reason to think the appraisal is wrong, you can formally challenge it. The process is called a Reconsideration of Value, and since 2024 it hasn't been a favor you ask for — it's a documented right with a required procedure behind it.

Fannie Mae's Selling Guide states that the lender must have policies and procedures in place for a borrower-initiated reconsideration of value, and must provide a disclosure to the borrower outlining that process when the appraisal report is provided. The same guide sets out exactly what a borrower's request has to include:

• Borrower name, property address, the effective date of the appraisal, the appraiser's name, and the date of the request
• Identification and description of the unsupported, inaccurate, or deficient parts of the report
• Additional data or comparable properties — not to exceed five — with their sources
• An explanation of why that new data supports a different value

Two limits worth knowing before you start. Only one borrower-initiated ROV is permitted per appraisal, so you get one attempt and it should be your best one. And it has to happen before closing.

What actually wins one

Read that list again and notice what it asks for: facts and comparable sales. Not disagreement.

Reconsiderations succeed when they correct something concrete — square footage recorded wrong, a finished basement counted as unfinished, a permitted addition missed entirely, a comparable sale the appraiser didn't have. They fail when they amount to "we think it's worth more."

So if you're going to use your one attempt, use it on something checkable. Pull the actual comps with addresses and dates. Find the permit. Measure the room. An appraiser presented with a fact they got wrong will usually correct it. An appraiser presented with an opinion will not.

The take-home

If you're selling: an appraisal is not a verdict on your pricing. It's a lender's risk check, done after the fact, by someone who has walked fewer houses on your street than your agent has. Price to the comps, and if a low appraisal arrives, ask what specifically drove it before you agree to reduce anything.

If you're buying: decide your appraisal terms when you write the offer, not when the number comes back. And know that if it comes in low and you have a real, factual reason to question it, there's a formal process with rules — and one shot at it.

Either way, the fifth price is the one that arrives when everyone thinks the negotiating is over. It usually isn't.

Which is the argument for reading this now rather than later. Almost everything that determines how a low appraisal goes — the contingency, the gap clause, whether your price was built on real comps in the first place — is settled weeks earlier, while it still feels theoretical. By the time the number lands, you're not deciding anymore. You're living with what you decided.

So if you're thinking about buying or selling in the next while and you'd rather get ahead of this than react to it, send me a message. Happy to walk through where the appraisal fits in the whole sequence, and what it takes to price a house so the fifth number isn't a surprise.
