The appraiser gives your lender an independent opinion of the home's market value. They get there by comparing the house to recent sales of similar homes nearby and by walking through it to check its size, features, condition, and location. The lender uses that number to decide how much it will lend you. It is not the same as a home inspection, and it is not a report card on your taste. Here is exactly what the appraiser is doing behind that closed front door, so it stops feeling like an unknown.
Quick Answer
The appraiser tells the lender how much the home is worth by comparing it to recent sales of similar homes and inspecting its size, condition, features, and location. The lender uses that independent number to decide how much it will lend. The appraiser values the home for the lender, while an inspector checks the condition for you. They are two different jobs and two different reports.
Appraisal vs Inspection: Two Different Jobs
This is the distinction I make with every first-time buyer, and it comes straight out of the homebuyer roadmap. The appraiser values the home for the lender. The inspector checks the condition for you. The easiest way to keep them straight is to remember who each one works for.
| What it does | Appraiser | Home Inspector |
|---|---|---|
| Who it works for | The lender | You, the buyer |
| What it decides | How much the lender will lend | Whether the home is in sound condition |
| What it measures | Value, built from sales and condition | Condition of systems and components |
| What happens if it finds a problem | It may adjust the value you can borrow against | You negotiate repairs or a credit |
I put it this way all the time: the lender cares about value, and you care about condition. The appraiser and the inspector can walk through the same house on the same day and hand back two very different reports, and both did their job right. Want the full picture?

The Three Big Levers That Move the Number
When the appraiser forms an opinion of value, they are really balancing three levers. Knowing them tells you what is driving the number before it ever comes back.
Comparable sales, the comps
This is the heaviest lever of the three. The appraiser anchors the value to what similar homes nearby have actually sold for, not what is listed or what anyone hopes for. This is the same logic behind a listing price vs market value.
Condition and features
The appraiser adjusts for how the home compares to those sold comps. Extra square footage, an added bath, a finished garage, updated kitchens, deferred maintenance. Every difference nudges the value up or down.
Location
Where the home sits within the neighborhood, the school zone, the commute into San Antonio or the Hill Country, all of it is baked into the comparison because it is baked into what nearby buyers paid.
If you want to see the comps the way an agent does, my breakdown of a comparative market analysis walks you through how the same recent sales are read from the buyer side.
What the Appraiser Walks Through
The appraiser is not grading your d�cor. They are documenting the physical facts of the house and noting how it compares to the comps. Here is the checklist they are working through as they move room to room.
- Measured square footage. Total living area is a big driver, and it is measured, not estimated.
- Layout and counts. Bedrooms, bathrooms, and how the rooms connect and flow.
- Upgrades and finishes. Updates to kitchens and baths, flooring, and anything a buyer would pay extra for.
- Condition of major systems. Roof, HVAC, electrical, plumbing, and foundation get a visual once-over.
- Obvious deferred maintenance. Worn or damaged items the next buyer would have to address, noted as adjustments.
- Photos and documentation. They photograph and note what they see so the value is supported and explainable.
Remember, the appraiser documents the condition but they are not your structural engineer. That is the inspector's lane. And none of this walkthrough is the same as the county's number. I break down assessed value vs market value so you never mix the tax bill with the lender's number.

The Comps Are the Real Story
Here is what actually decides the number: the appraiser compares the subject home to recently sold, similar homes in the area and adjusts for the differences. The finished garage adds value. The extra half-bath adds value. The sagging deck takes value away. Every adjustment is built on those sold comps, never on what a buyer hopes to pay or a seller hopes to get.
This is also why two nearly identical houses on the same street can appraise differently. Small differences in condition, features, and lot all shift the comparison. And it is why I push buyers to know the comps before they ever write an offer: the number stops being a surprise when you already understand what it is built from.
What if the comps land below your agreed price? Read what to do when the appraisal comes in low, and how to handle an appraisal gap if it shows up.
What the Number Means for You
The appraisal number matters because it sets the most the lender will lend against that home. Here is how to read the two outcomes.
Appraises at or above your price
You are set. The value supports the agreed price, your financing moves forward, and you are not on the hook for more cash.
Appraises below your price
You can ask the seller to bring the price down, agree to pay the shortfall yourself, or use your appraisal contingency to walk away cleanly.
A low appraisal does not kill the deal by itself. Walk through each option in my guide to a low appraisal and how an appraisal gap can be handled in your offer.
Can You "Prepare" for an Appraisal?
You do not stage for the appraiser the way you stage for a showing. They are documenting, not being impressed. But a few things genuinely help the process go cleanly.
- Keep it clean and accessible. Unblock the path to the attic, the water heater, and the breaker panel so the appraiser can document everything.
- Make the listing accurate. Correct room counts and square footage save your agent from correction headaches down the line.
- Do not hide problems. The appraiser documents what they find. Being upfront is always the smoother path.
If you are a seller getting ready for the value conversation, my notes on home staging explained separate the showing prep from what actually moves a number.
Patrick's Take
"The appraiser isn't judging your taste, they're pricing the house for the lender. Know the comps, know the condition, and the number stops being a mystery."
Quick Answers
Do I have to be at the appraisal?
No. The lender orders the appraisal and the appraiser coordinates access, usually through the listing agent or seller. You generally will not need to be there.
Who pays for the appraisal?
In a typical Texas purchase, the buyer pays the appraisal fee, usually at application or as part of the costs wrapped into the transaction. It shows up among the buyer costs you plan for. I cover how these fit into your total picture in closing costs for Texas buyers.
How long does the appraisal take?
The walkthrough itself is usually quick, often under an hour. Receiving the final written report can take a few days after the visit.
What if the house appraises lower than my offer?
You have real options: negotiate the price down, cover the difference yourself, or use your appraisal contingency to walk away. None of them have to end the deal. I walk through each route in what happens if the appraisal comes in low.
