About DealSight

DealSight turns Zillow into an investment analysis tool. While you browse listings, it automatically calculates cash flow, ROI, and cap rate for every property on the map — and displays them in a sortable panel so you can rank deals by what actually matters to investors. No spreadsheets. No manual math. ────────────────────────────────────── WHAT YOU GET ────────────────────────────────────── ▸ Cash flow, ROI, and cap rate for every listing on screen ▸ Sortable panel — rank by price, cash flow, ROI, or cap rate ▸ Estimated rent for properties missing Zillow rent data ▸ Color-coded returns so the best deals stand out instantly ▸ Multi-family support — estimates per-unit rent from comparable listings ▸ HOA, property tax, insurance, maintenance, and management all factored in ▸ Filters by property type (SFH, condo, townhouse, multi-family, etc.) ────────────────────────────────────── CUSTOMIZE TO YOUR NUMBERS ────────────────────────────────────── Click the DealSight icon to dial in your assumptions: • Interest rate • Down payment % • Closing costs % • Property tax rate (auto-applied by state) • Insurance rate • Maintenance reserve • Property management fee All settings sync across your devices automatically. ────────────────────────────────────── PRIVACY ────────────────────────────────────── DealSight collects zero data. All calculations happen locally in your browser. No accounts, no tracking, no external servers. ────────────────────────────────────── NOTES ────────────────────────────────────── • Works on Zillow for-sale search pages • Numbers are estimates — always do your own due diligence before investing • Not affiliated with Zillow
