We believe every property professional deserves access to accurate, affordable rental market data - not just the largest enterprises.
RentComp API was built on a simple idea: rental comparable data should be accessible to everyone who needs it, not locked behind enterprise contracts and six-figure licensing fees.
Property managers, lenders, appraisers, and developers all need reliable rental data to make informed decisions. Yet for most of them, the existing options are either too expensive, too fragmented, or too unreliable to build on. We set out to change that.
Our API aggregates data from public listing feeds and government sources, normalizes it into a consistent format, and delivers it through a simple REST interface. One API call gives you estimated rent ranges, nearby comparables, HUD Fair Market Rents, and market trends - the same data that used to require multiple vendor contracts and weeks of integration work.
Rental market data today is broken for most professionals:
RentComp API makes quality rental data available at a fraction of the cost:
Our API powers applications across the rental and real estate ecosystem.
Show market rent suggestions to landlords and automate rent pricing within your platform.
Verify rental income estimates for DSCR loans with comparable data and confidence scores.
Access comparable rental listings and market trends to support property valuations.
Integrate rental data into investment tools, analytics dashboards, and proptech applications.
RentComp is built by a small, focused team of engineers and data specialists with deep experience in real estate technology, data engineering, and API infrastructure.
Our founding team brings backgrounds spanning property management software, financial data platforms, and geospatial analytics. We have seen firsthand how fragmented and inaccessible rental data is for most companies, and we are building the solution we wished existed.
We are a remote-first team that values shipping working software over meetings, and we believe the best products come from staying close to the people who use them. If you are building something with rental data, we want to hear from you.
We show our data sources, methodology, and confidence scores. You should always know how our estimates are generated and how reliable they are for your use case.
Quality rental data should not require an enterprise budget. Our usage-based pricing means you pay for what you use, starting at a price point any developer can afford.
Three endpoints. Clean JSON responses. Comprehensive documentation. We obsess over developer experience because we know your time is valuable.
We continuously validate our estimates against market data and refine our models. Confidence scores tell you exactly how much to trust each result.
We process only the data necessary to serve your requests. We do not sell user data, and we are transparent about what we collect and why.
We build for uptime. Redundant infrastructure, automated monitoring, and cached responses ensure your applications stay fast and available.
