Google Capital is getting into real estate.

The newest Google investment arm, which focuses on putting money into established companies, announced today that it has invested $50 million in online real estate marketplace Auction.com.

While it doesn’t typically get as much hype as competitors Trulia and Zillow, Auction.com says it has established the largest online real estate market, with more than $26 billion worth of property sold through the site since it launched in 2008. This latest investment now values Auction.com at $1.2 billion.

Most likely, Google wanted to get a stake in Auction.com before it goes public. The company brought on a CFO last year, and it’s rumored to be planning for an IPO soon. Both Trulia and Zillow have gone public successfully, but Auction.com’s size and auction platform may make it even more desirable for investors.

Prior to this investment, Auction.com raised more than $91 million from investors, including Stone Point Capital, Starwood Capital Group, and others.
