Appraisal Basics
What Is a Home Appraisal?
An independent, professional opinion of market value — and the process behind how an appraiser actually arrives at it.
A home appraisal is an independent, professional opinion of a property's market value, developed by a state-licensed or certified appraiser. Unlike a rough estimate or a sales pitch, an appraisal follows a structured, standards-based process — and the appraiser has no financial stake in what number the final report shows.
Why an Appraisal Gets Ordered
Appraisals get requested any time someone needs a supportable, independent opinion of value rather than a rough guess — most commonly for one of the following reasons:
How an Appraiser Arrives at an Opinion of Value
Research
The appraiser reviews public records, recent sales, and neighborhood market trends before ever setting foot on the property.
Inspection
For most assignments, the appraiser inspects the property — measuring, photographing, and documenting condition, layout, and features.
Analysis & Report
The appraiser selects and adjusts comparable sales, reconciles the data, and documents a supportable opinion of value in a formal report.
The result is a documented, defensible opinion — not a guess and not a negotiating position. That's what separates an appraisal from a real estate agent's price opinion or an automated online estimate.
How This Differs From Other "Value" Numbers
Homeowners often encounter several different value figures for the same property — a real estate agent's Comparative Market Analysis (CMA), an automated online estimate, and a county's tax assessment — and it's easy to assume they should all match. They generally don't, and understanding why is useful before you rely on any single number for an important decision.
