"StreetEasy is an incredibly strong and recognized brand in New York City, and complements Zillow's dominant and growing national brand."

The website has been around since 2006 and has established partnerships with the biggest real estate brokerages in the city. Co-founder and CEO Michael Smith is looking forward to his company's newest alliance: "We're very excited to be joining forces with Zillow ... as we continue our commitment to data integrity, innovation and collaboration with the local real estate community."

Subject to customary closing conditions, Zillow expects to seal the deal within the next few weeks.

Zillow also announced today a public offering of 2.5 million shares. Certain shareholders are offering an additional 2.5 million shares.
