First the news on horseback. We’ll come back and gloss it again, but you’re likely to learn more by listening to the podcast linked below with Zillow.com’s David Gibbons.<\/p>\n

The news, from Zillow’s press release:<\/p>\n

Real estate Web site Zillow.com today announced a major expansion and upgrade to its database of nearly all homes in the country — increasing data coverage from 70 million to 80 million U.S. homes in 48 states, or 88 percent of all homes in the country. Zestimate values are now available on three out of four U.S. homes, or 67 million, up 68 percent from when Zillow launched in 2006. New areas with Zestimates include the states of Alabama, Arkansas, Delaware, Iowa, Idaho, Indiana, Kansas, Kentucky, Louisiana, West Virginia and New Hampshire.  <\/p>\n

Zillow today also announced it has dramatically expanded and improved its Zestimate algorithm, incorporating 20 times the number of statistical models than before that factor in more local and home-type variables and now integrate homeowner-edited home facts — such as the number of bedrooms, bathrooms or square footage. More than one million homes have been claimed and updated by their owners to date, contributing to improved Zestimate accuracy on many of these homes. Incorporating these changes along with continued algorithm upgrades have resulted in a 12 percent improvement in Zestimate accuracy nationwide. Many larger metropolitan markets, such as the greater San Francisco, Miami, Los Angeles and Atlanta areas, have some of the most significant accuracy gains at 18 percent, 21 percent, 22 percent and 28 percent respectively.<\/p><\/blockquote>\n

There’s more. This was leaked earlier this evening by TechCrunch.com:<\/p>\n

The other big news is that Zillow is joining Yahoo Real Estate, Trulia, Oodle, Homes.com, Realestate.com, Vast.com and others in adopting a standard way for brokers and multiple listings services (MLSs) to send in their real estate listings in a feed format. That way brokers can use the same data format for all the different real estate search engines and Websites. It is called the Real Estate Transaction Standard (RETS). That should make it easier for brokers to propagate their listings everywhere.
