Setting a rent price by guessing, or by copying whatever a neighboring landlord charges, is a surprisingly common and surprisingly costly habit among smaller landlords who don't have access to enterprise-grade rental data tools. RentCast built its business around making that specific piece of data affordable and accessible, offering rent estimates and rental comps at a genuinely low monthly price alongside a developer API for teams building their own applications on top of the data.
What is Rentcast?
RentCast is a real estate data platform providing nationwide access to real-time property, rental, listing, and market data across more than 140 million rental and commercial properties and over 40,000 US zip codes. It offers accurate rent estimates, nearby rental comps, and local market statistics through a simple two-tier pricing model, with a genuinely usable free tier and a low-cost Pro plan for expanded access. Beyond the consumer-facing platform, RentCast offers a developer API used by teams and applications wanting to build products on top of comprehensive property and rental data, positioning it as more accessible and modern compared to larger, enterprise-focused data providers like ATTOM or CoreLogic.
Key features

Pros
- Genuinely affordable entry point, with a functional free tier and a low-cost $19 per month Pro plan, undercutting many enterprise-focused data competitors
- 140 million-plus rental and commercial property records across more than 40,000 zip codes provide broad, genuinely useful national coverage
- Rent alerts and portfolio tracking extend the platform beyond a one-off lookup tool into ongoing rental management support
- Developer API is more accessible and modern compared to larger, enterprise-focused providers like ATTOM or CoreLogic, making it approachable for smaller teams and startups
Cons
- No refunds are offered for subscription charges except under unique circumstances, and canceling doesn't trigger a refund for the remaining subscription period
- Free plan is limited in the number of properties and rental comps accessible, suitable mainly for new investors evaluating their first rental property
- No mobile app is currently available, limiting access to the web platform specifically
- Doesn't support full lease accounting, so landlords needing that specific capability will need a separate property management tool alongside RentCast
Pricing
RentCast offers a Free plan with limited property and rental comp access by default for new users, and a Pro plan priced at $19 per month, or $12 per month when billed annually, unlocking the platform's full range of rental data services. No refunds are provided for subscription charges except under unique circumstances, and canceling a subscription allows continued access to premium features until the end of the current billing period rather than an immediate downgrade. A separate developer API is available with its own pricing structure for programmatic access. Confirm current plan features and API pricing on the official RentCast website before subscribing.
Best for
RentCast is best suited to landlords, property managers, and investors wanting affordable, accurate rent estimates and rental market data without an enterprise-level budget, along with developers wanting a modern, accessible API for building real estate applications. It fits AI Real Estate workflows centered on rental pricing and portfolio management specifically. Landlords needing full lease accounting or broader property management functionality should pair RentCast with a dedicated property management platform, since RentCast focuses specifically on rental data rather than end-to-end property operations.
Use cases
- Getting an accurate rent estimate for a specific property before listing it
- Researching nearby rental comps to validate a proposed rent price
- Tracking local market statistics and historical rent trends for an investment area
- Setting up an alert to know when it's time to consider raising rent on an existing property
- Building a custom real estate application using RentCast's developer API
Supported platforms
- RentCast is a web-based platform accessible through any modern browser, with no dedicated mobile app currently available, and a separate developer API for programmatic access.
Languages
- RentCast's platform interface and data are primarily oriented around English-language, US-based rental and real estate markets.
Integrations
- RentCast's primary integration path is its developer API, letting teams and applications build custom products on top of its property and rental data.
Things to consider
- Review RentCast's no-refund policy before subscribing, since charges are non-refundable except under unique circumstances, and canceling only stops future billing rather than refunding the current period. Landlords needing full lease accounting or broader property management functionality should plan to pair RentCast with a dedicated property management tool, since it focuses specifically on rental data rather than end-to-end operations. Users specifically wanting mobile access should note that RentCast currently has no dedicated mobile app, limiting access to the web platform.
How the tool compares
RentCast's closest comparison for rental data specifically is Mashvisor's rental comp and market data tools, though RentCast is more narrowly focused on rent estimates and market statistics while Mashvisor also compares traditional versus Airbnb strategies for property acquisition decisions. Against HouseCanary and other enterprise-focused property data providers, RentCast offers more flexible, self-service pricing and a more modern API, making it considerably more accessible for smaller businesses, individual landlords, and startups. Landlords and smaller teams wanting affordable, self-service rental data tend to find real value in RentCast specifically; institutional buyers needing the deepest possible valuation accuracy and analytics may still prefer an enterprise platform like HouseCanary.
