Before the rise of real estate technology, it was hard to know a home’s value until a state-licensed appraiser visited the property and made an estimate, weighing pros like a chic patio against cons like a mildewy basement. 

Today, artificial intelligence and neural networking can do the work of appraisers. Zillow’s free Zestimate tool is one popular option on the market. 

“It’s always been this attempt at a starting point in home valuation for everyone who’s bought and sold and owns a home,” said Nicholas Stephens, director of product management at Zillow


What Is Real Estate Technology? 

Real estate technology comes in many forms, and it can be classified as any website, app or software used to find, sell or manage real estate. Real estate tech overlaps with proptech (property tech), which is typically used by real estate professionals, underwriters, developers, property managers, title companies and banks. 

Zillow is a prime example of real estate tech. Since it debuted in 2006, the Zestimate’s internal algorithm has drawn on traditional real estate metrics (bedroom and bathroom count, square footage) as well as contextual data, like local tax records. When people list their homes for sale on Zillow, they upload pictures; the Zestimate can “see” these photos using cutting-edge computer vision techniques and factor elements like natural light and curb appeal into its estimates.

The Zestimate’s median error hovers just above 3 percent. In other words, half of its estimates are within 3 percent of a home’s actual selling price. That’s a massive improvement since Zillow’s early days when the Zestimate had a median error of 14 percent.

Zillow isn’t the only company that foresees a shift in real estate appraisal. The more powerful AI technology becomes, the more automated valuation models (or AVMs) sprout up.

Real Estate Technology Trends

Tech has fundamentally changed how the real estate sector operates. For one, it has sped up transactions. Discovering real estate listings and setting up showings used to take days. Today, not so much. On-demand information and services are standard in this hyper-connected era, and the real estate industry has responded to consumer demand for immediacy.

Redfin debuted Instant Updates more than a decade ago, and the feature has only gotten faster in the intervening years.

“People can sign up for notifications for the types of homes that they’re looking for,” said Jen Chao, vice president of engineering at Redfin. “We can notify our customers faster than anybody else, so they can be the first to find out about homes that are hitting the market or price changes.”

Real estate technology has also accelerated the booking process for viewing homes. Redfin’s “Book It Now” feature is just one example. The feature allows users to schedule a home tour in just a few clicks. 

In fact, a recent trend — instant buying, or iBuying — extends this on-demand ethos to selling a home, a sometimes interminable-seeming process. But selling to iBuyers takes only a few days. The companies make prompt, algorithm-driven offers, pay in cash and sell homes themselves — often sprucing them up in the process.

Today, iBuying represents only a sliver of all real estate transactions, but that’s poised to change. In 2018, Zillow Offers bought fewer than 700 homes, according to the New York Times, but it expects to scale that up to 5,000 homes per month by 2024.

For her part, Redfin’s Chao sees proptech heading toward what she calls the “complete solution.” Redfin hopes to eventually become a one-stop shop, so it can provide a seamless home-buying experience. But this doesn’t mean real estate professionals and agents will be pushed out. 

“Real estate is a highly personal service,” Chao said. “[We use] technology to streamline and get rid of the [tasks] that software can do really well, to free up time for agents to focus on the things that require the human touch.”
