A company set up by Agassi and his wife Steffi Graf, a former world No. 1 tennis player, said on Monday it had partnered with privately owned Exclusive Resorts LLC, a time-share company headed by AOL co-founder Steve Case to develop "luxury resort communities."

"As I begin the next chapter of my life, I am looking for ways to pursue a career in business, specifically in real estate," Agassi, 36, said in a statement.

Agassi ended his 21-year professional tennis career on Sept. 3 after losing at the U.S. Open on Sept. 3. During his career he won 60 career titles including eight grand slam crowns.

Agassi said Agassi Graf Development LLC and Exclusive Resorts would co-develop luxury resort communities in the United States and overseas which would have Agassi/Graf tennis and fitness facilities as their central amenities.

He will become a senior advisor to the company.

Exclusive Resorts, which specializes in luxury destination clubs and has about 2,400 members, plans to develop homes in these new communities and make them available to members.

Earlier this month Agassi and Graf unveiled plans to develop a luxury mountain project, Fairmont Tamarack, in Donnelly, Idaho, in conjunction with Miami-based Bayview Financial LP.

Fairmont Hotels & Resorts will manage this luxury hotel and residences which will have a classic resort and spa as well as a mid-mountain site. It is expected to be completed in 2009.
