What it does
Tired of scraping Redfin or stitching together HUD/Census data? ZipMarketData gives you clean, structured JSON for every US ZIP code in one API call. ✅ Market stats & inventory ✅ 12-month price history ✅ Gross rental yields (by bedroom) ✅ Affordability indices ✅ Property estimates + full investment metrics (cash flow, cap rate, buy-vs-rent) Data pulled daily from Redfin + HUD + Census Bureau. Every single response includes the exact data_source so you always know where it came from.
Cap rate, cash flow, rental yield and market temperature for 28,000+ US ZIP codes, built from Redfin public data, HUD Fair Market Rents and Census ACS. Free tier, no credit card.
Type any US ZIP code and instantly see median price, estimated rent, gross yield, cash flow, and market temperature — all from government and MLS sources. No spreadsheet required. Use the no-code dashboard to research deals, or integrate the API directly into your own tools. Create an account in under a minute. No credit card. You get 15 free lookups per day to evaluate markets — each lookup returns market, rental and investment figures together. Type in a ZIP or click a quick-pick market.
