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

the next-generation real estate brokerage, today announced that an
update to the algorithm for the Redfin
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, 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
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.*
