How to Estimate Your Home's Value

This home value estimator uses the sales comparison approach: it calculates the average price per square foot from your comparable sales and adjusts for your property's condition to estimate a market value range.

Finding Good Comparables

The best comps are within 0.5 miles, sold within 90 days, with similar sq footage (±15%), beds, and baths. Use Zillow's sold listings filter, Redfin, or ask a real estate agent for MLS data. Redfin and Zillow show sold prices on their maps — look for the most recent sales nearest your property.

Why Hire an Appraiser

Professional appraisers adjust for dozens of factors including lot size, specific location within the neighborhood, garage vs no garage, basement sq footage, quality of updates, and view. For any financial decision (sale pricing, refinancing, estate planning), an appraisal from a licensed appraiser is worth the $400-$600 cost.

Frequently Asked Questions

Is this home value estimator free?

Yes, completely free with no signup required. All calculations run locally in your browser.

Is my data safe?

Absolutely. Everything runs in your browser — nothing is sent to any server.

How accurate is an online home value estimator?

Online estimators (including Zillow's Zestimate) typically have a median error rate of 3-7% in active markets and much higher in low-turnover areas. They're useful for ballpark estimates. For an accurate valuation, hire a licensed appraiser or ask a real estate agent for a Comparative Market Analysis (CMA).

What makes a good comparable sale?

Good comps are: sold within 6 months, within 0.5-1 mile, similar square footage (within 15-20%), same number of bedrooms, similar condition and updates, and same neighborhood. The fewer adjustments needed between a comp and your property, the more reliable the estimated value.

What is a professional appraisal needed for?

A licensed appraisal is required for: mortgage financing or refinancing, estate settlements, property tax appeals, divorce proceedings, and legal disputes. Online estimators are informational only and are not accepted for these purposes.
