Frequently asked questions about US Home Value Calculator

Is this as accurate as Zillow or Redfin?

No. AVMs use millions of data points and ML models; this calculator gives a transparent rule-of-thumb estimate to validate other sources.

What ppsf should I use?

Pull recent sold comparable sales within the same zip code and average their price per livable square foot.

Does basement area count?

Generally only finished above-grade area. Use a separate adjustment for finished basements (often 30–60% of above-grade ppsf).

How wide should the range be?

The default ±8% suits stable markets. Wider ranges (±10–15%) are reasonable for rural or highly variable markets.
