Appraisal Gaps: When a Financed Buyer's Loan Comes in Short

An appraisal gap is the difference between the price a financed buyer agreed to pay and a lower value in the appraisal their lender ordered. The lender sizes the loan against the appraised value, so the loan comes in short of what the contract assumed. The gap then has to be closed in one of four ways: the buyer brings more cash, the seller lowers the price, the two split it, or the buyer cancels under an appraisal contingency if the contract has one. For a seller, that makes the appraisal a risk line on the listing side of the comparison, one that a cash sale does not carry.

This article is part of the Cash Offer vs. Listing knowledge center. It explains why gaps happen, which Pomona Valley houses are prone to them, and what they do to your net. Questions about a specific loan belong with the buyer's lender; questions about your contract belong with your agent or an attorney.

What the lender's appraisal is, and who controls it

The appraisal in a financed sale is a certified appraisal: an independent opinion of value by a licensed or certified appraiser, ordered by the buyer's lender to decide how much it will lend. Three points follow from that.

• The lender works from the appraised value. Lenders measure a loan against the appraised value of the property, the loan-to-value ratio. If the value is lower than the price, the loan the buyer expected may not be available at the same down payment.
• Nobody may lean on the appraiser. Federal rules on valuation independence prohibit trying to influence an appraiser's value through coercion, pressure or reward. A seller or agent may send the lender relevant information, such as comparable sales, through proper channels.
• The buyer gets the copy. Federal rules require the lender to give the applicant, the buyer, a copy of the appraisal on a first-lien home loan. The seller sees it only if the buyer shares it.

None of this is the same as a CMA, an automated estimate or a cash purchase offer. The open-market read on this site is a preliminary estimate, not an appraisal. If you need a certified appraisal for your own purposes, for example before you price a house that is likely to appraise tight, that is a job for a licensed appraiser; Mr. Cali Offers refers it to Mr. Cali Appraisals, a separate appraisal practice that explains the difference.

Four ways an appraisal gap gets resolved

OutcomeWhat happensEffect on your net

Buyer covers the gap

The buyer adds cash to make up the difference

- (none, if the buyer has the cash)

Price reduced to the appraised value

You sign an amendment lowering the price

- (the full gap comes off)

Gap split

Buyer adds some cash, price comes down by the rest

- (part of the gap comes off)

Contract cancelled

The buyer exits under an appraisal contingency

- (carrying costs continue while you relist)

Before any of those, the buyer's lender may accept a request to reconsider the value, usually supported by comparable sales the appraiser did not use. Whether that is available, and how it works, is a question for the lender. It sometimes moves the value and often does not.

Some buyers write into their offer that they will cover a shortfall up to a stated amount. That language is only as strong as the buyer's cash, which is why an agent will ask to see it. How such a clause reads in your contract is a question for your agent or an attorney.

Which houses come in short, and why

Gaps cluster on houses where the appraiser cannot find comparable sales that support the price, or cannot count all the space. In the Pomona Valley that points to a few recurring kinds of house.

Unpermitted living area

Appraisers generally cannot give full value to living area that was never permitted, and FHA and other government-backed loans apply property standards that unpermitted work can fail. The post-war single-story tracts south of Holt Avenue in Pomona, where converted garages and back units are common, are the clearest case. In Claremont, enclosed porches, back houses and garage conversions on older lots are the items that shorten appraisals. Barns, casitas and enclosed patios with mixed permit histories on larger San Dimas lots do the same. When the buyer priced the house by its full square footage and the appraiser counts less, a gap is close to built in. See selling a house with unpermitted additions.

Thin comparable sales

Pomona's Hacienda Park Historic District mixes eras from adobes to mid-century modern, and comps there have to be chosen house by house. Hillside houses in Claraboya are priced from other hillside sales, never from the flat tracts below. When there are few true comps, an appraiser has less to support a price set by enthusiasm, and the value lands closer to what the nearest recorded sales show.

Condition items the lender cares about

A lender's appraiser can call out health and safety items that must be fixed before the loan funds: a roof at the end of its life, an old electrical panel, active leaks. That is not a value gap in the strict sense, but it has the same effect on a seller: either money for repairs before closing or a renegotiation.

What a gap does to the two numbers

On a written comparison, the appraisal shows up as a risk line on the open-market side, next to inspection renegotiation and financing fall-through. It is a risk, not a certainty, so it is described rather than subtracted in full. The cash side has no lender, so it has no appraisal line; its price already reflects the space and condition as they are.

That is why a house prone to a gap can make the two nets closer than the two prices. A listed sale that loses part of its price to an appraisal amendment, after months of carrying costs and a cancelled first escrow, can end up nearer the as-is cash number than the list price suggested. How the cash side is built is in how much cash buyers pay, and where the difference goes; the listing side's own lines are in net proceeds, line by line.

When the appraisal is not a real risk, list

Most houses appraise without trouble. If all the living area is permitted, the systems are sound, and recent sales on your own blocks went to financed owner-occupants at prices like the one you expect, the appraisal risk line is small, and listing usually nets more than a cash offer. In that case the written recommendation is to list, and you are introduced to a designated local expert who works your neighborhood. The cash offer vs. listing pillar sets out the full comparison.

If your escrow already failed on an appraisal

You have the same choices as before, with better information. You can relist and price to what the appraisal and the comps support, look for a buyer whose loan or cash does not depend on that appraisal, legalize the space and try again, or take an as-is offer that prices the house as it stands. The appraisal itself is the buyer's document, but if they share it, it tells you what the appraiser could and could not count. That is useful to whoever writes your next number.

What this looks like in practice

These are the kinds of files that come in, described without names or figures.

• A Pomona seller whose FHA buyer's appraisal did not count a converted garage, ending an escrow and leaving the house back on the market.
• A Claremont owner with an enclosed back porch used as a bedroom, deciding before listing whether to legalize it or price it as it is.
• A San Dimas owner of a larger lot with a casita, comparing a financed sale's appraisal risk with an as-is price.
