What makes an appraisal come in low, and what can an LO fix first?

Most low appraisals are set up before the appraiser arrives

By the time a low value hits your inbox, the cause is usually a few weeks old. It was in the contract, the listing data, the missing addendum or the comps nobody looked at when the offer went in.

That is good news for a loan officer. It means a lot of the damage can be spotted, and some of it fixed, before the order goes out. Not by nudging the appraiser. By making sure the appraiser gets complete, accurate facts and by telling your borrower the truth early.

Here are the five causes I see most, with an honest answer on which ones you can do anything about. Some you can fix. Some you can only forecast. One you can only explain, ideally before your borrower has already told their family the house is "basically theirs."

For the borrower's side of the same problem, send them why did my home appraisal come in low. This post is the view from your desk.

The five causes, and which ones you can fix first

Notice what is not on the list: a bad appraiser. They exist, like bad loan officers exist. But if you plan for the five above, most surprises stop being surprises.

Causes one and two: the price and the facts

A price stretched past the evidence. Fannie Mae has the lender use the lower of the sales price or the appraised value for the loan-to-value ratio. If the contract outran the closed sales, no paperwork fixes that. What you can do is see it. Ask the agent which closed sales support the price. If the best answer is a vibe, run the numbers for the borrower now: down payment, mortgage insurance and cash to close if the value lands short.

Wrong or missing facts. This is the most fixable cause and the most common one I see in disputes. The new kitchen nobody pulled a permit for in the listing. The bedroom count that came from a 1978 tax record. The square footage the listing copied from somewhere optimistic. Fannie Mae requires appraisers to measure using the ANSI Z765-2021 standard, so the appraiser's number can differ from the listing for good reasons.

Facts the appraiser does not have can't help the value. A one-page list of upgrades with dates, rough costs and permits, sent through your lender's process before the inspection, does more good than a three-page rebuttal after the report. It is also the cheapest value anyone will ever add to a house.

Causes three, four and five: comps, condition and credits

Thin or stale comps. In a rising market, the newest closed sales are already a few weeks behind the contracts being written today. Fannie Mae requires the appraiser to analyze how the market changed from each comp's contract date to the effective date, and says time adjustments, or the lack of them, must be supported by evidence. You can't create sales. You can ask the agent for the recent and pending sales that support the price, so they can be shared properly if they are not already in the appraiser's data.

Condition and repairs. Fannie Mae requires an appraisal to be made subject to repairs when deficiencies affect safety, soundness or structural integrity. A known roof leak or a missing water heater does not get better because nobody mentioned it. Find out early and decide with the agents whether it gets fixed first.

Concessions. A price raised to cover a seller credit is a price the appraiser has to test like any other, and Fannie Mae requires the appraiser to report the total concessions on the deal. On the comps, Fannie Mae says concession adjustments must reflect the market's reaction, which is not automatically dollar for dollar. Write credits plainly into the contract. Inflating the price to fund them is how a $20,000 credit turns into a $20,000 appraisal gap.

Where the line is: facts yes, targets no

Everything above lives inside appraiser independence. Here is where the walls are on loans sold to Fannie Mae:

• No target value. The Appraiser Independence Requirements prohibit giving an appraiser an anticipated, estimated, encouraged or desired value. A copy of the sales contract for a purchase is the exception, and it is expected.
• Production staff stay out. Loan originators and anyone paid on a closed loan may not select appraisers, order or manage the appraisal, or have substantive conversations with the appraiser about value. Your appraisal desk or AMC handles that.
• Facts and questions are allowed. Any party may ask the appraiser for more explanation of the basis for a value, or to correct objective factual errors.
• After the report, use the ROV process. Fannie Mae allows one borrower-initiated reconsideration of value per appraisal, with up to five additional comparable sales, submitted through the lender before closing.

In short: you can hand the appraiser a better flashlight. You can't tell them where to point it.

The pre-order checklist

1. Full contract package. Every counteroffer, addendum and credit, signed.
2. Concessions in writing. Closing costs, buydowns and repair credits named in the contract.
3. Upgrade sheet. Kitchen, baths, roof, HVAC, windows, additions, with dates and permits.
4. Corrected data. If the listing's bedroom count or square footage is wrong, say what is right and how you know.
5. Known defects. Leaks, missing systems or safety items, and whether they will be fixed before the inspection.
6. Access. Gate codes, attic, crawl space, detached buildings, and who will be there.
7. The price story. Which closed and pending sales the agent used to support the offer.
8. The borrower talk. What happens to cash to close if the value comes in 3% or 5% short.

Anything that is a fact goes through your lender's process. Anything that is a hope stays in the borrower meeting.
