How the Foster City valuation tool works
What is the Foster City Multi-AI Home Valuation Tool?
The Foster City Multi-AI & 3-Portal AVM tool is a free home-valuation instrument from Equitas Homes. It benchmarks three real-estate portal estimates — a live Zillow Zestimate® (via Bridge Interactive) alongside Redfin and Homes.com — against a three-model AI appraisal panel (Google Gemini, OpenAI, and Anthropic Claude) reasoning over local MLS comparables. It then applies the standard San Mateo County documentary transfer tax of $1.10 per $1,000 and a 1% listing fee to show a seller's true net equity.
3-Portal AVM Benchmarking
Cross-checks a live Zillow Zestimate® (via Bridge Interactive) with Redfin and Homes.com figures against MLS comparable sales, so your Foster City value reflects several independent models — not a single black-box estimate.
Multi-AI Comparative Market Engine
Three independent AI appraisers — Google Gemini, OpenAI, and Anthropic Claude — each weigh Foster City comparables for proximity, recency, size, and lot nuances, then reconcile to a defensible range with the adjustment math shown.
Real Net Equity Calculation
Instantly deducts the standard San Mateo County documentary transfer tax of $1.10 per $1,000 and models a 1% Equitas listing fee against a traditional 3%, so you see the equity you actually keep — not just a headline price.
