Most online home value tools use broad averages and miss by hundreds of thousands. ShopProp Intelligence uses 10 hyper-local comps, interactive sliders, and real MLS data.
Zillow, Redfin, and other platforms estimate home values using automated valuation models (AVMs). These algorithms pull from public records, tax assessments, and broad market data — but they can't see inside your home.
Here's what they miss:
ShopProp's home value estimator mirrors the appraisal process — the same methodology lenders require before approving a mortgage. Here's how it works:

This data helps buyers evaluate whether an area is appreciating, plateauing, or declining — and helps sellers time their listing for maximum return.
Most online estimators (Zillow Zestimate, Redfin Estimate) can be off by 5-20% or more. They use automated algorithms that miss property condition, view, waterfront access, and recent renovations. ShopProp's estimator uses 10 hyper-local comparable sales with 7 interactive adjustment sliders for significantly more accurate values.
The most accurate way to determine your home's current value is a CMA using recent sales of similar properties nearby. ShopProp's free estimator pulls 10 comparable sales from real MLS data and lets you adjust for condition, location, view, and more. Search any address at shopprop.com — no sign-up required.
ShopProp's 20% Rule flags any listing priced more than 20% above its comparable-sales-based fair market value. This catches overpriced homes before you make an offer, potentially saving tens of thousands of dollars.
