An appraisal gap is the difference between the price you agreed to pay and the lower value the lender's appraiser assigns. Offer $1.3M on a Redmond home that appraises at $1.25M, and you have a $50,000 gap. Because your lender only lends against the appraised value — not your offer — that shortfall has to be closed before you can close. Here's why it happens, your four options, and how Eastside buyers handle it without overpaying or losing the house.
Why appraisal gaps happen on the Eastside
An appraisal is the lender's independent check that the home is worth what you're borrowing against it. In fast, competitive markets like Bellevue, Redmond, and Kirkland, winning offers are often pushed above the last comparable sale — sometimes by tens of thousands — through bidding wars. The appraiser, meanwhile, is looking backward at recent closed sales ("comps"). When prices climb faster than comps can catch up, the appraised value can land below your winning number. That's not a mistake — it's the appraiser doing exactly their job on a rising market.
Why the gap is your problem, not the bank's
Say you're putting 20% down on that $1.3M home — a $260,000 down payment and a $1.04M loan. If the appraisal comes in at $1.25M, the lender will now only lend 80% of $1.25M, not $1.3M. The purchase price in your contract hasn't changed, so the difference has to come from somewhere. The bank won't cover it — which is why the gap becomes a cash question for you and a negotiation with the seller.
Your four options when a home appraises low
What you can actually do depends on the contingencies in your purchase agreement — but the options fall into four buckets:
- Pay the difference in cash. You bring the $50,000 gap to closing on top of your down payment. This keeps the deal on your original terms — but only works if you have the reserves.
- Renegotiate with the seller. Ask them to lower the price to the appraised value, or meet in the middle. Sellers who don't want to relist (and risk the next buyer's appraisal doing the same thing) often move.
- Walk away using an appraisal contingency. If you kept an appraisal contingency, a low appraisal lets you cancel and recover your earnest money. Without that contingency, canceling can cost you the deposit.
- Challenge the appraisal. If the appraiser missed better comps or made a factual error, your lender can submit a Reconsideration of Value. It doesn't always work, but a well-documented rebuttal occasionally moves the number.
A worked example
Numbers make this concrete. Imagine a Kirkland home listed at $1.2M that draws six offers. You win at $1.3M with 20% down, planning a $260,000 down payment and a $1.04M loan. Then the appraisal lands at $1.25M — a $50,000 gap. Here's how each path plays out:
- Pay cash: you close at $1.3M but bring $310,000 to the table — your original $260,000 down payment plus the $50,000 gap.
- Renegotiate: the seller drops to $1.27M; you split the difference and cover $20,000 in cash instead of $50,000.
- Use the contingency: if you kept an appraisal contingency, you cancel and walk away with your earnest money intact.
- Gap coverage kicks in: if you promised to cover up to $40,000, you pay $40,000 of the gap and the seller must decide whether to cover the last $10,000 or lose the sale.
The right move depends entirely on your cash reserves and how much you want this house — which is why the decision should be made before you write the offer, not in a panic after the appraisal.
When does the appraisal happen — and who pays?
The appraisal is ordered by your lender shortly after mutual acceptance, usually once your inspection contingency is satisfied, and typically takes a week or two to complete. You, the buyer, pay for it — generally $600–$900 in the Seattle area — as part of your closing costs. Because it comes fairly early in the timeline, a low appraisal usually surfaces with enough runway to renegotiate or make a plan before your closing date.
The appraisal contingency: your safety net
An appraisal contingency says that if the home appraises below the purchase price, you can renegotiate or cancel without losing your earnest money. It's one of the core protections in a Washington offer, alongside the financing and inspection contingencies. In a balanced market you'd almost always keep it. The catch: in a competitive multiple-offer situation, sellers strongly favor offers that waive it — which is where gap coverage comes in.
Appraisal gap coverage — the competitive-offer tool
To win without fully waiving your protection, many Eastside buyers offer appraisal gap coverage: a clause promising to cover a shortfall up to a set amount in cash. For example, "Buyer will pay up to $40,000 above appraised value, provided the appraisal is at least $1.26M." This tells the seller you're serious and partly self-insured against a low appraisal, while capping your exposure. A few rules of thumb:
- Only promise cash you actually have. Gap coverage is a real financial commitment, not a bluff — if the appraisal comes in low, you must pay it.
- Cap it deliberately. Covering "any" gap is open-ended risk; a dollar cap protects you.
- Coordinate it with your down payment and reserves. Gap cash comes on top of your down payment — make sure both are covered.
How to protect yourself before you offer
- Know your real cash ceiling. Before writing a competitive offer, decide the maximum gap you could actually cover. That number sets how aggressive you can safely be.
- Get fully underwritten, not just pre-qualified. A strong financing position gives you room to structure appraisal terms confidently.
- Study the comps yourself. If recent sales don't support your price, an appraisal gap is more likely — go in with eyes open.
- Don't waive blindly to win. Waiving the appraisal contingency can win the house and then cost you dearly. Waive with a strategy, not out of panic.
This is exactly the kind of judgment call a good buyer's broker earns their keep on — weighing how much gap risk to take against how badly you want the home. New to the whole process? Start with the first-time buyer guide for King County & the Eastside.
Keep more cash on hand — with a flat fee
An appraisal gap is a cash problem, so the more cash you keep, the more options you have. That's where your agent's fee matters. A traditional buyer's agent charging ~2.5% on a $1.3M home costs about $32,500. A flat $2,999 buyer service does the same job — structuring your offer, advising on gap coverage, and negotiating a low appraisal — while leaving tens of thousands in your pocket, money that can go straight toward covering a gap. Compare the two in flat fee vs. a traditional buyer's agent, and see who pays the buyer's agent in Washington.
