Get an accurate home value using real MLS data, 10 comparable sales, and 7 interactive adjustment sliders. No sign-up. No email. Completely free.
A Comparative Market Analysis (CMA) is the method real estate professionals and appraisers use to determine a property's fair market value. Instead of relying on ZIP-code-wide averages or automated algorithms, a CMA examines actual recent sales of similar properties near the subject home and adjusts for differences in condition, features, and location.
A proper CMA answers the question every buyer and seller needs answered: "What would a reasonable buyer actually pay for this property today?"
Most online tools call their estimates a "CMA" but really just run an algorithm. ShopProp's Property Analysis tool gives you the real thing — an interactive CMA you control.
ShopProp's CMA tool was built by a managing broker who's completed 4,000+ transactions since 2007. It mirrors the appraisal process — the same methodology lenders require before funding a mortgage.
Each slider adjusts the estimated fair value based on how the subject property compares to its comps:

A CMA (Comparative Market Analysis) uses hand-picked comparable sales with manual adjustments for condition, location, and features — the same approach professional appraisers use. A Zestimate is Zillow's automated algorithm that relies on broad averages and public records without accounting for property condition, view quality, or recent renovations. ShopProp's CMA gives you 7 interactive sliders to fine-tune your value.
