Top 10 Best Real Estate APIs

Have you been wondering about where to find the best real estate APIs and how you can put them to good use for your business? No worries—we’ve got you covered. In this post, we’ll give you a clear understanding of how real estate APIs can make a real difference for real estate professionals, and which ones you might want to check out first. 

 

But First, What Is a Real Estate API?

API stands for application programming interface, a set of programming code that queries data, parses responses, and sends instructions between one software platform to another. Real estate APIs deliver housing, rental, mortgage, or property condition data on a specific property, or multiple properties, as a service provided by the companies that offer them. Whether you’re a developer, product manager, broker, investor, or financial services professional, real estate APIs can play a vital role in your success.  

 

Real estate APIs serve different functions. One API might provide listing data such as property type, year built, number of bedrooms and bathrooms, price per square foot, Airbnb and traditional rental income, demographics, and neighborhood analytics. Another might zero in on property-centric deeds, tax, mortgage, foreclosure and other market data. Still others might provide instant, accurate insights on current physical attributes of a property—type and condition of roof, the presence of swimming pools, fencing, yard debris, and other characteristics that may impact valuation, risk scoring, and trends that can affect it over time. 

 

How Are Real Estate APIs Used? 

Data has always been the lifeblood of real estate investing, and for the last three decades, the Internet has played a central role in making that data ever more accessible. But in the age of Zillow, iBuyers, and single family rental property (SFR) investment sites like Roofstock, companies involved in transacting, investing, and trading rental properties have been racing to leverage technology to help them make faster, smarter business decisions. 

 

APIs, which are built using XML or JSON open standard data exchange formats, provide a ready means to integrate key data points into user workflows. At their most essential, APIs act as messengers that take requests from a user and then tell the associated backend system to return the appropriate intel related to the user’s query. 

 

Typically available by subscription, APIs come in different flavors. Some deliver basic datasets—MLS-based real estate listings retrieved via API don’t entail the use of analytics to provide value-added intelligence, for instance. But many data providers employ various forms of AI or machine learning to interpret raw data to create useful information relative to their area of specialty. Underwriters, investors, and traders interpolate this data into their own models to make acquisition or divestment decisions quickly.
