Redfin Improves Accuracy of Its Popular Automated Home-Value Estimate and Expands It to 80 Total U.S. Markets

The updated Redfin Estimate is 9.7 percent more accurate for
on-market homes

SEATTLE–(BUSINESS WIRE)–Redfin (www.redfin.com),
the next-generation real estate brokerage, today announced that an
update to the algorithm for the Redfin
Estimate has substantially increased its accuracy, less than a year
after the automated home-value estimate’s initial launch. The Redfin
Estimate is an important part of the brokerage’s rapidly growing
home-selling service, as it is used by both home sellers and listing
agents as a starting point for the process of setting a listing price
for a home.

“The Redfin Estimate has quickly become one of the most popular
technologies on our website and mobile apps among home sellers, as well
as buyers and homeowners,” said Bridget Frey, chief technology officer
at Redfin. “We’ve seen a huge jump in the number of visits to off-market
homes on Redfin.com, a sign that our industry-leading data science is
helping people make decisions about buying and selling homes.”

The updated Redfin Estimate is 9.7 percent more accurate for on-market
homes and 7.8 percent more accurate for off-market homes compared to its
original version launched last year. As of October 21, the updated
Redfin Estimate had a median error rate of 1.80 percent for homes listed
for sale and 6.28 percent for off-market homes. This means that when a
home that is on the market sells, the Redfin Estimate will be within
1.80 percent of the sale price half of the time; when a home that is not
currently listed sells, the Redfin Estimate will be within 6.28 percent
of the sale price half of the time.

The Redfin Estimate error rate is dynamic and fluctuates depending upon
the data available at a given time. Redfin posts the most current
national and local error rates on the Redfin
Estimate page. The error rate updates daily for on-market homes and
weekly for off-market homes.

Today’s announcement also includes a geographic expansion, doubling the
number of metro areas in which the Redfin Estimate is available to 80
metro areas, nearly every market Redfin serves. The Redfin Estimate is
now available for about 65 million homes in the following metros.*

About the Redfin Estimate

The Redfin Estimate is designed to serve as a starting point to help
homeowners and home sellers determine their home’s value. Homebuyers use
it as a reference point when deciding how much to offer on a home for
sale, and Redfin agents often use it as part of their pricing analysis.
Redfin encourages anyone who is interested to talk to a Redfin real
estate agent in their neighborhood for a more detailed understanding of
what a home is worth, with no obligation to list or buy a home with
Redfin.

Redfin users can find the Redfin Estimate for a home by typing an
address into the search box on Redfin.com. The Redfin Estimate appears
at the top of the home listing and sale record pages on Redfin.com. The
Redfin Estimate is free, and anyone can sign up for Redfin Home Report
emails to get monthly updates on a home’s value.

The Redfin Estimate operates on cloud technology and uses the most
complete and up-to-date data available on home listings and sales. As a
real estate brokerage, Redfin has 100 percent complete, direct access to
multiple listing services (MLSs), the databases that real estate agents
use to list properties.
