Anna Kournikova has sold her 6,630-square-foot home in Miami Beach's exclusive Sunset Island for $7.4 million, the Wall Street Journal reported. Former top 10 player Kournikova paid $5 million for the seven-bedroom waterfront home in 2000. The property has about 150 feet of frontage on the Intracoastal Waterway and a coral-rock pool deck that surrounds a pool and Jacuzzi. Kournikova and her longtime partner, singer Enrique Iglesias, are building a new home in South Florida that is said to cost somewhere around $20 million.
