The Home Appraisal Process, Step by Step

A home appraisal is an independent, third-party estimate of what your property is actually worth — and if you’re getting a mortgage, your lender requires one before they’ll fund the loan. It’s not optional and it’s not the same as a home inspection. In my experience, this is the step in the transaction that catches first-time buyers off guard, mostly because they don’t understand what the appraiser is looking at or what happens if the number comes back lower than the purchase price. Here’s the home appraisal process from start to finish, plus what I tell clients in Phoenix, Denver, Sacramento, and Omaha when their appraisal doesn’t match expectations.

Why Lenders Require an Appraisal

Your lender isn’t just loaning money to you — they’re loaning money against the house. If you ever stopped making payments, the property is the collateral that backs the loan. An appraisal protects the lender from lending more than a home is actually worth, and honestly, it protects you too. Nobody wants to overpay for a house by $40,000 and find that out the hard way when they try to sell or refinance three years later.

This is true whether you’re putting 20% down or 3%, and it applies whether you’re buying in Scottsdale or a smaller Nebraska town. The appraisal is ordered after you’re under contract, once you’ve locked in a lender and moved forward with your purchase loan.

Who Orders It and Who Picks the Appraiser

Here’s something a lot of buyers don’t realize: your loan officer doesn’t pick the appraiser, and neither do you. Federal rules require lenders to use an appraisal management company (AMC) that assigns a licensed, independent appraiser at random from a pool. This exists specifically to prevent anyone from pressuring an appraiser toward a number that supports the deal. So when I tell clients “we don’t control the appraisal,” that’s not a dodge — it’s the law.

Typically:

• The lender orders the appraisal within a day or two of your contract being accepted
• The buyer pays for it upfront, usually a few hundred dollars, though the exact fee varies by property type and location
• The appraiser contacts the listing agent or seller to schedule the visit
• The report is typically completed and delivered to the lender within a week to ten days

What Happens During the Home Appraisal Process

The appraiser walks the property, takes photos, measures square footage, and notes the condition of the roof, HVAC, foundation, and major systems. They’re checking for safety and habitability issues too — exposed wiring, missing handrails, a water heater in a closet without proper venting, that kind of thing. In Arizona, they’ll also note things like pool condition and any obvious deferred maintenance that shows up more starkly under desert sun.

After the walk-through, the appraiser pulls comparable sales — “comps” — of similar homes that sold recently nearby. This is where local market knowledge matters. A ranch home in a Denver suburb doesn’t compare well to a newer build a mile away in a different school district, even if the square footage is close. The appraiser adjusts for differences: lot size, upgrades, garage spaces, age of the roof, and so on, then lands on a final opinion of value.

What Appraisers Are Not Doing

They’re not doing a full home inspection — they won’t test every outlet or run the dishwasher. And they’re not setting the sale price; they’re confirming whether the agreed-upon price is supported by the market. Those are two different jobs, and mixing them up is a common source of confusion.

What Happens on a Low Appraisal

This is the scenario in the home appraisal process that causes the most stress, so let’s walk through it plainly. Say you’re under contract for $450,000 and the appraisal comes back at $430,000. Your lender can only base the loan amount on the lower of the purchase price or the appraised value — not the contract price you agreed to. That $20,000 gap has to get resolved somehow, and there are really only a few paths forward:

• You pay the difference in cash. If you have the funds, you cover the gap out of pocket so the deal closes at the original price.
• The seller lowers the price to match the appraised value — common in a buyer’s market, less common when inventory is tight.
• You split the difference through renegotiation, which happens more often than people expect.
• You challenge the appraisal. If you or your agent spot comps the appraiser missed, or an error in square footage or condition notes, you can request a reconsideration of value. It doesn’t always work, but it’s worth pursuing if you have solid evidence.
• The deal falls through, which is exactly why I always recommend keeping an appraisal contingency in your purchase contract when the market allows it.

In my experience, low appraisals show up more often in fast-moving markets where buyers are bidding above list price to win a home — think parts of Phoenix or the Denver metro during a competitive stretch. It’s less common in steadier markets like much of Nebraska, where prices tend to track more closely with recent sales.

How to Prepare Before the Appraiser Arrives

You can’t control the outcome of the home appraisal process, but you can make sure the appraiser has accurate information. If you or your agent know of recent upgrades — a new roof, updated HVAC, finished basement — put together a simple list with dates and costs. Clean up obvious clutter so rooms measure and photograph clearly. And make sure the home is accessible; a locked shed or blocked attic access can delay the report.

Before you even get to this stage of the home appraisal process, it helps to get pre-approved so your lender has already reviewed your file and can move quickly once the appraisal comes back — whether that means clearing you to close or working through a value gap.

FAQ

How long does the home appraisal process take?
Typically one to two weeks from the time it’s ordered to when the lender receives the final report, though timing can shift based on the appraiser’s schedule and property complexity.

Can I use my own appraiser?
No — lenders are required to use an independent appraisal management system to assign the appraiser, which keeps the process unbiased.

Does a high appraisal help me?
It can. If the home appraises for more than the purchase price, it may support a stronger equity position from day one, though your loan amount is still based on the purchase price, not the higher value. You can run the numbers to see how that plays out for your specific loan.
