The Home Appraisal, Explained: How It Works and What to Do When It Comes In Low

Your offer got accepted, the inspection went fine, and then your lender emails: "The appraisal came in at $312,000." You're under contract at $325,000. Nobody explained this part, and suddenly a deal that felt done has a $13,000 hole in it. The appraisal is the one step in a financed purchase that buyers consistently underestimate — because it's ordered by the lender, done by someone you never meet, and only becomes visible when it causes a problem. This guide covers what it is, why it matters to your loan, and exactly what your options are when the number is short.

What an appraisal is (and isn't)

An appraisal is a licensed appraiser's written opinion of what a home is worth, prepared for the lender. The lender isn't curious about the house — it's protecting the collateral. If you stop paying, the bank ends up owning the property, so it wants an independent check that the house is actually worth what it's lending against.

Three things an appraisal is not:

• It isn't an inspection. The home inspection is for you and looks for defects. The appraiser notes obvious condition issues but is there to estimate value, not to test the water heater.
• It isn't the assessed value. The parish assessor's number drives your property taxes and often bears little relationship to what a buyer would pay today.
• It isn't the market price. The market price is what a willing buyer and seller agreed to — your contract. The appraisal is one professional's estimate of what the data supports. Usually those agree. Sometimes they don't, and that's where the trouble starts.

Who orders it and who pays

Once you're under contract and your loan is in process, the lender orders the appraisal. On most conventional, FHA, and VA loans the lender is required to go through an appraisal management company or a rotation system so neither you, your agent, nor the loan officer picks the appraiser. That independence is the point — it's why you can't just hire a friendly one.

You pay for it, typically $450 to $700 for a standard single-family home in Louisiana and more for large, rural, or unusual properties. It's usually charged up front or shortly after you sign your loan disclosures, and it's non-refundable even if the deal falls apart. It shows up on your closing cost statement as a "paid outside closing" line.

Timing: the appraiser usually visits within one to two weeks of being assigned, and the report follows a few days later. In a busy market or a rural parish with few appraisers, plan on longer, and make sure your contract's financing deadline allows for it.

What the appraiser actually does

The visit itself is short — often 20 to 45 minutes. The appraiser measures the exterior, walks the interior, photographs each room, and notes the condition, layout, bedroom and bathroom count, upgrades, and anything that clearly hurts value (foundation cracks, roof damage, unpermitted additions). On FHA and VA loans they also check specific minimum property standards: peeling paint on pre-1978 homes, working utilities, a roof with remaining life, no exposed wiring, and so on. Those loans can require repairs before closing that a conventional loan would ignore.

The real work happens afterward. The appraiser pulls comparable sales — "comps" — which are recent closed sales of similar homes nearby, ideally within the last three to six months and within about a mile in a subdivision (wider in rural areas). They adjust each comp up or down for differences: a comp with one fewer bathroom gets a dollar adjustment added; a comp on a bigger lot gets an adjustment subtracted. After adjustments, the comps should point to a range, and the appraiser picks a value inside it.

The mechanics matter because they explain why appraisals sometimes miss. The appraiser can only use sales that have closed, so in a fast-rising market the comps lag the price you agreed to. And if the house is unusual for its area — the only new construction on a street of 1970s ranches, the one house with a pool, a heavily renovated home surrounded by originals — there may simply be no clean comps, and the value gets conservative.

Why the appraisal matters to your loan

Your lender bases its loan on the lower of the purchase price or the appraised value. That single rule is what creates the "appraisal gap."

Say you're buying at $325,000 with 10% down. You planned to put in $32,500 and borrow $292,500. The appraisal comes in at $312,000. The lender now lends 90% of $312,000 — $280,800 — not 90% of the contract price. You still owe the seller $325,000. The difference between what the bank will lend and what you owe just grew by $11,700, and someone has to cover it.

This is also why the appraisal is tied to your pre-approval and your loan type. Your approval was for a payment and a loan amount based on the contract price; a low appraisal changes the loan-to-value ratio, and on a conventional loan that can also change your mortgage insurance and rate.

When the appraisal comes in low: your four options

First, don't panic and don't react in the first hour. Your agent and loan officer will both see the report, and the contract's appraisal contingency (if you kept one) gives you a defined window to respond. These are the moves, roughly in the order most buyers try them.

1. Ask the seller to lower the price

The simplest fix. A low appraisal is evidence, on paper, that the house is worth less than the contract — and any other financed buyer is likely to hit the same number. Sellers who understand that often come down, at least partway. Your leverage is strongest when the seller has no backup offers and the market has cooled since they listed. It's weakest in a bidding war, where the next buyer in line may have waived their appraisal contingency entirely.

2. Pay the difference in cash

If you have the money and still believe in the price, you can bring the gap to closing on top of your down payment and closing costs. In the example above, that's another $11,700 — real money, and money that isn't building equity on paper the day you close. Buyers do this in tight markets when the house is right and the alternative is starting over. Just be honest with yourself about whether that cash was your emergency fund.

3. Meet in the middle

The most common outcome. The seller cuts the price part of the way, you cover the rest in cash, and the deal moves forward. The split is negotiable — it usually reflects who has more to lose from walking. If you're wondering how this interacts with your deposit, our guide to earnest money vs. down payment covers where the money sits during the negotiation.

4. Walk away

If you kept an appraisal contingency, a low appraisal lets you cancel the contract and get your earnest money back, as long as you act within the contingency deadline and in the form the contract requires (usually written notice through your agent). If you waived it, walking away means forfeiting the deposit unless another contingency — financing, inspection — still gives you an exit. Read your contract before you decide, not after.

The fifth option: challenge the appraisal

You can also ask the lender for a reconsideration of value. This is a formal request, usually submitted by your agent through the loan officer, pointing out factual errors (wrong square footage, missed bedroom, a renovation the appraiser didn't credit) or better comps the appraiser didn't use. It has to be specific — "we think it's worth more" goes nowhere, but "the report lists 1,650 sq ft and the parish records show 1,910" can move the number. Success rates are modest, and it can take a week or more, so start it immediately if you're going to try. As a last resort your lender may allow a second appraisal, at your cost, but they're under no obligation to use it.

Protecting yourself before the appraisal

The best appraisal-gap strategy is the one you set up when you wrote the offer.

Keep the appraisal contingency if you can. In a balanced market it costs you little and gives you a clean exit. If you must compete, an appraisal gap clause is the middle ground: you agree in advance to cover a shortfall up to a stated dollar amount ("buyer will cover up to $10,000 below appraised value"). It shows the seller you're serious without writing a blank check.

Know the comps before you bid. If your agent's comps say $310,000 and you're offering $325,000 to win, you already know an appraisal problem is likely. Decide before you offer whether you're prepared to cover it, and size your offer accordingly.

Don't over-inflate the offer with seller-paid closing costs. A $325,000 offer with $10,000 in seller credits is functionally a $315,000 sale, but the appraiser sees $325,000. Asking for large credits pushes the contract price up and makes a gap more likely.

Make the appraiser's job easy. Your agent can send the appraiser a list of recent comps and a summary of upgrades. Appraisers aren't required to use them, but a well-organized packet reduces the chance that a relevant sale gets missed.

A note for sellers

If you're on the other side of this, the appraisal is the same hurdle from a different angle. The house you priced to sell has to price to appraise too, or your financed buyer's deal wobbles. Make sure your agent has a comp package ready for the appraiser, be present or available for questions about upgrades, and — if you're weighing multiple offers — notice which ones include an appraisal gap clause or a larger down payment. A higher offer that can't clear the appraisal is worth less than a slightly lower one that can.

The bottom line

The appraisal is the lender's check that the house is worth what it's lending against, and the loan is sized to the lower of the appraisal or the contract price. When it comes in short, you have a defined set of moves: renegotiate, pay the difference, split it, challenge the report, or walk away under your contingency. Which one is right depends on how much you want the house, how much cash you have, and what your contract says — which is why the smartest appraisal decisions get made at the offer stage, before the appraiser ever pulls into the driveway.
