How Is External Data Used in Real Estate?

Real estate decisions used to be impressionistic, not data-driven. However, this has changed with the advent of big data—in particular, buyer sentiment data available online.

People increasingly use the internet to find homes and investment properties. And it’s no wonder: the data revolution makes finding data on neighborhoods, real-time traffic estimations, areas of late night activity, noise levels, restaurants, outdoor activities, parks, and customer reviews easy to find, and eliminates some of the typical buyer confusion. The massive amounts of data on available houses online mitigates the risks of investing in a property with unknown history.

Realtors, investors, and home-seekers also use data analysis to predict risk and market trends with predictive analytics, fast property evaluations, market trend analysis, and location scouting.

Realtors use market data history to make accurate property appraisals and evaluations to set prices. Consequently, home buyers and investors can use the same data to put forward counter-offers of their own.

Not only are vast amounts of data available to be evaluated, but machine learning models allow these evaluations to be made in minutes. As a result, realtors can move on current consumer trends faster.

Finally, realtors and investors use geospatial data to collect and display location information. In this way, house hunting and location scouting become much more accessible.

How are Machine Learning Models Used in Real Estate?

AI holds great promise for the field of real estate; it has already changed so much about the way agents, mortgage lenders, developers, and home-buyers work.

Home Value Appraisal or Rental Price Prediction

Machine learning programs process large amounts of data to evaluate home values and rental prices. These programs use geospatial, traffic, and neighborhood data as well very detailed information on house data, like square footage and upgrade details.

In fact, value appraisals and rent prediction models can even collect data on how much vegetation is on the lawns in the neighborhood.

Buyer Identification

Realtors use deep learning algorithms to both identify and market to potential buyers and renters. These algorithms track and measure online activity—particularly social media activity—to find the most relevant leads.


Underwriting based on risk calculations can be evaluated with AI, saving investors and more a lot of time working on this issue.

Developers also identify construction sites with AI platforms that specialize in hyper-local zoning regulations.
