Redfin Corp., the online real estate search service and brokerage, plans in 2013 to file preliminary papers to go public with the goal of a stock sale the following year, Chief Executive Officer Glenn Kelman said.

“We expect to be public in 2014,” he said in an interview yesterday at Bloomberg’s Los Angeles offices. The Seattle-based company is searching for a chief financial officer in anticipation of the IPO, which is tentative, Kelman said.
