Automated valuation models (AVMs) — the instant online value estimates offered by various real estate websites — are convenient, but they answer a fundamentally different question than a licensed appraisal does, and understanding that difference matters before you rely on either one.

How an Automated Estimate Actually Works

An AVM applies a statistical model to public records and recent sales data to generate a value estimate in seconds — no inspection, no individual property analysis, and no professional judgment involved in the specific number it produces.

Real Limitations Worth Understanding

No physical inspection — condition and upgrades are usually assumed or estimated, not verified
Relies on public records that may be outdated or contain errors
Struggles with unique properties, rural areas, or thin sales data
Provides a value range or point estimate with a stated (often wide) margin of error
Not accepted for lending, legal, or property tax appeal purposes

Where a Licensed Appraisal Fills the Gap

A licensed appraiser inspects the actual property, verifies condition and characteristics firsthand, and applies professional judgment to comparable-sales selection and adjustment — which is exactly why appraisals, not automated estimates, are required for lending, legal, and tax matters.

Frequently Asked Questions

They can be reasonably close in markets with lots of recent, similar sales data — but they carry a real margin of error and don't account for a property's actual current condition or unique characteristics.

No — Georgia Boards of Equalization and tax assessors generally require credible market evidence, not an automated model's output, to support a value dispute.

Automated models don't know about renovations, current condition, or property-specific factors an appraiser would document firsthand — and public record data they rely on can lag behind reality.

In some specific, limited scenarios lenders may use alternative valuation products, but this is determined by the lender's own policies and loan program requirements — not something a borrower can substitute on their own.

Not necessarily — they can be a reasonable starting point for a general sense of value, as long as you understand their real limitations and don't rely on them for decisions that require a supportable, independent opinion.
