The real estate market is still hot… online. Trulia, a popular real estate search site, has raised a $15 million fourth round led by Deep Fork Capital LLC, along with past backers Sequoia Capital, Accel Partners and Fayez Sarofim & Co. The company has now raised a total of $33 million. The company, which claims to be the biggest online real estate company, recently rolled out its own ad network (naturally), centered around real estate — evidently that bubble hasn’t burst yet. Actually the company argues that the housing crisis helps, as it’s changed the way people search for homes (so they say). In addition to listings search, it offers community tools and info on regional trends and neighborhoods. The company’s most well-known competitor is heavily backed Zillow.com. Release.
