homes.plus — Investor Overlay

Cap rate, cash-on-cash, demand signals, and a deal score on every Zillow listing.

homes.plus overlays the numbers investors actually need onto every Zillow listing — without ever leaving the page. Open any property at zillow.com/homedetails/... and a clean side panel appears with: • Estimated monthly rent • Cap rate • Cash-on-cash return • MAO (Max Allowable Offer, 70% rule) • A 0–100 deal score No copy-paste, no spreadsheet, no five tabs open at once. Underwrite a property in the time it takes to scroll past the photos. WHY THIS EXISTS Real estate investors evaluate dozens of listings per week. The data is on Zillow; the math is not. Most analysts solve this by exporting addresses to Excel, pulling rentometer values, and computing metrics by hand. homes.plus does it inline. THE RENT MODEL Our rent estimate is generated by a Random Forest model trained on tens of thousands of public rental listings, with stronger coverage in New Jersey and New York. In other markets, the overlay falls back to national averages and clearly labels the coverage level so you know when to trust a number and when to double-check. WHAT THE METRICS ASSUME • Cap rate uses the 50% rule (operating expenses ≈ 50% of rent), a standard investor convention • Cash-on-cash assumes 25% down at 7.2% interest, 30-year amortization • MAO uses the 70% rule with a rehab estimate capped at 30% of price • Deal score combines cap rate and cash-on-cash into a single sortable number These are conventions, not financial advice. Use them as a first-pass filter, not a substitute for due diligence. PRIVACY The extension only runs on Zillow listing pages. It reads the publicly displayed price, beds, baths, sqft, and address from the page and sends them to api.homes.plus to compute the metrics. No account, no login, no tracking, no analytics.
