Palm Beach County Clerk of Court records show Giuliani, 65, and his wife, Judith, purchased a 2,064 square-foot unit at Palm Beach's Southlake condominium on Thursday, The Palm Beach (Fla.) Post's "Real Time" blog reported Friday.
The couple bought the unit from the Jean Daniels Cluett Trust.
Palm Beach County Property Appraiser records show the Southlake unit is the second condominium purchased by the former Republican presidential candidate and his wife in Palm Beach.
The couple also owns a condominium unit at Palm Beach Towers they bought in 2004, the Post blog reported.
The New York Daily News said Giuliani operates a successful consulting business and has not openly spoken about any intentions to retire to Florida.
