Seattle-based Zillow is giving away another, $350,000 home, as part of a promotion to spur Facebook likes on the company's homepage. According to Zillow, it is working with home builder Pulte Homes to give away a brand new, $350,0000 Pulte home in a "I Want A New Home!" sweepstakes. Zillow said that users can "Like" Zillow on Facebook in order to enter the sweepstakes. The sweepstakes is the second time Zillow has teamed with Pulte on a home giveaway--the company also gave away another, $350,000 home back in 2010 with Pulte. In addition to the Facebook contest and home, Zillow also said it is offering up $5000 to a winner who "pins" listings from Zillow on Pinterest.
