Trulia.com is expected to debut on the New York Stock Exchange tomorrow. The San Francisco-based Internet company offers real estate listings and housing market information, and is part of a growing cottage industry that has househunters turning to the web to find properties.

Trulia isn't allowed to grant interviews as it goes public. But Spencer Rascoff, the CEO of competitor Zillow.com, says these companies make it easier to shop.
 
"It's about giving consumers access to information that previously was locked up in county courthouses or secret databases," Rascoff said. "And helping these consumers have access to that information, whenever and wherever they want it, including on smartphones."

Trulia's stock is expected to price at $14 to $16 per share.
