(Reuters) -Home brokerage Compass is in advanced talks to acquire Warren Buffett’s real-estate brokerage business, the Wall Street Journal reported on Thursday, citing people familiar with the matter.

The acquisition price could not be determined, the report said, adding that a deal could come together soon if talks don’t hit any last-minute snags.

Compass and Berkshire Hathaway (NYSE: BRKa ) did not respond to a Reuters requests for comment.

Earlier this week, Rocket Companies said it would acquire real estate listing platform Redfin (NASDAQ: RDFN ) in an all-stock deal valued at $1.75 billion, in a move to boost its lending business.

Compass, which operates in 35 U.S. states and Washington DC, with more than 33,000 agents, is among the largest U.S. real estate brokerages by sales volume.

HomeServices of America, a major residential real estate brokerage in the country, has been battling rising costs in recent years related to legal settlements over brokerage commissions.
