The Realty Mole real estate and rental data API provides on-demand access to real-time property rent estimates and comparable rental listings. We have nationwide coverage for nearly all residential and commercial properties in the US.

Maintaining an accurate data set of property records is our top priority. We obtain our data from a variety of sources, including public records, recorded deeds, tax assessors and online listing websites, and process over 500 thousand updates on a daily basis.

We offer a free API plan which includes up to 50 free API calls per month, so you can test our API and develop your integration without costly upfront commitments or long-term contracts.

Here are just some examples of what you can do with our API:

• Get real-time property rent estimates (AVM) based on the unique characteristics of each property and nearby comparable listings
• Retrieve a list of up to 25 comparable rentals for each property, including their attributes, listed rents, and distance from the subject property

Our support team is here 7 days a week to answer your questions and provide help with your integration. You can contact us by clicking the “Contact” button at the top right of this page, or by posting a new thread on the Discussions page of our API hub.

Below are some general considerations to keep in mind when working with our API.

Property Types

We use the following property types in our API, both for the propertyType query parameter, as well as any property type fields returned via our API as part of property or listing records:

• Single Family (default): a detached, single-family property
• Condo: a single unit in a condominium development or building, which is part of a home owner’s association (HOA)
• Townhouse: a single-family property that shares walls with other adjacent homes, and is typically part of a home owner’s association (HOA)
• Manufactured: a pre-fabricated or mobile home, typically constructed at a factory
• Duplex-Triplex: a single unit/apartment within a residential multi-family building (2-4 units)
• Apartment: a single unit/apartment within a commercial multi-family building or apartment complex (5+ units)

Rent Estimates for Multi-Family Properties

For multi-family properties (“Duplex-Triplex” or “Apartment” property types), our API returns property rent estimates for a single unit, not the entire multi-family or commercial building.

So, when providing specific property attributes in your request (ex. bedrooms, bathrooms, squareFootage), you should provide values for a single unit that you’d like to get a rent estimate for, not a combined total for the building.

Distance Measurements

Please note, that all distance radius query parameters (ex. maxRadius), as well as any distance measurements or fields returned via our API are measured in kilometers.
