Accurate rental data is the foundation of our platform, and we do everything we can to ensure we have the most accurate and up-to-date rental data available to our users.

Below are answers to frequently asked questions about our rental data sources, quality and regional availability.

How accurate are your rent estimates?

We calculate each rent estimate based on similar nearby rental property listings and their unique characteristics.

Our rent estimation algorithm takes into account the location, type, size, layout and listing age of each comparable property, and uses a weighted average formula to calculate the rent estimate of the property you're searching for.

In addition to our rent estimate, you can view a rent estimate range and the exact comps that were used to calculate it.

Where does your rental data come from?

We scan and catalog rental property listings from some of the most popular online listing websites and directories.

This allows us to compile a catalog of virtually all current and historical rental listings in the United States, that we can then use in our rent estimation algorithm.

How often is your data updated?

We scan and catalog new rental listings daily to make sure we always have the most accurate information. All of our rent estimates are calculated in real-time based on the available rental data.

What areas does your rental data cover?

We have nationwide coverage for residential properties in the United States, with over 140 million properties in our database. Our rental data covers both single-family properties, as well as multi-family and apartment buildings.

We also have coverage for nearly all US zip codes, and are able to show average market rents, market rents broken down by bedroom size, the number of rental listings broken down by bedroom size, as well as historical rent trends for each market.

RentCast currently does not support and is not available in other countries.
