What it really isRentCast — rental market data platform and property data API for real estate investors and developers.

Our takeRentCast has two products on one dataset: a web app where investors check rent estimates, comps and market trends, and a property data API for developers.

RentCast says it covers 150M+ US residential and commercial properties. Both the app and the API have permanent free plans, so you can test the data before paying.

Why we rate itRare combination of a polished investor-facing web app and a serious REST API under one roof, at prices accessible to solo investors and small PropTech teams alike.

The free tier is genuinely useful, not crippled.

The catchAPI costs scale quickly for high-volume use cases; the web app free tier caps at just 5 comps per property.

Coverage and estimate accuracy can lag in thin or rural markets.

Best / not good for

Best for

Independent landlords and rental property investors pricing units or evaluating acquisitions
PropTech developers needing a US property data API with predictable per-request pricing
Analysts tracking neighborhood rent trends and occupancy across portfolios

Not good for

Properties outside the US (coverage is US only)
High-volume data pipelines where per-request API costs add up
Investors who need more than 20 comps per property

Trade-offs

Friction report

Trade-offs to know before signing up.

Time to value
Fast: new accounts start on the free plan, and Pro has a 14-day free trial.
Scale breakpoint
API overage rates ($0.015–$0.20/req) make high-volume programmatic use expensive; large portfolios (50+ units) require custom pricing.
Walled garden
Low: data exports are available and the REST API gives programmatic access; no proprietary lock-in beyond the estimates model.

Still a fit?

If none of these block you, start on the free plan.
