RentCast is a decent rent lookup tool. PropData is a platform — 16 live data sources, 166M+ county assessor parcels, FEMA hazard risk, AI investor signals, and a proprietary estimate engine. All at $79/mo flat. No per-call fees. Ever.
Move the slider to see your real monthly cost at scale.
RentCast does one thing well — rent estimates for a specific address or ZIP. If that's all you need, it's fine. The problem starts when you need more context, more data types, or more scale.
⚠️ At 10,000 calls/month, RentCast's per-call pricing runs $100–500 depending on your plan. PropData is $79. At 50,000 calls/month the gap becomes $500–2,500 vs $79.
✓ PropData includes 12 data sources RentCast doesn't have — FEMA Natural Hazard Risk, FRED live mortgage rates, 166M+ county assessor owner records, AI investor signals, Community Safety Score, Opportunity Zone flags, USDA eligibility, comps engine, geocoder, skip trace, building permits, and Census ACS affordability data.
To get rent data, market velocity, and mortgage rates with RentCast you need 3 separate API integrations. With PropData it's one call.
When you call /v1/market, PropTechUSA.ai's 200+ Cloudflare Workers fan out in parallel — hitting Zillow, Realtor.com, Redfin, HUD, Census, FHFA, FEMA, and FRED simultaneously. All 16 sources resolve in parallel. You wait for one round-trip. Under 50ms from the nearest edge node.
These are the signals that separate a rent lookup from a market intelligence platform.
RentCast is a rent lookup. PropData is a platform that includes rent lookup plus 15 more things — and our Miss Flywheel closes any gap in real time.
