The Cayman Islands are a dream destination for second-home buyers. Here, backyards are replaced by beaches and temperatures usually donÂ’t dip below tepid. If youÂ’re looking to acquire an address in this island paradise, consider Castillo Caribe on Grand Cayman. At 48,000 square feet, the hulking beachfront estate—“palace” might be a more appropriate word—offers an unending complement of amenities, including 250 feet of beachfront, a 5,000-square-foot great room with 50-foot ceilings, a 400-bottle wine cellar, a spa, a Cuban-style courtyard, a combination billiards room and bar/lounge, his-and-her studies, a 4,000-square-foot basement play room, a tennis court, workout room, and a mock grotto, all on four livable levels and 1.4 acres of land. In addition to its over-the-top offerings, Castillo Caribe is bound to appeal to would-be buyers thanks to its location in the Caymans, which enjoy offshore status. For owners, this means no local taxes whatsoever—not property taxes nor income, capital gains, or inheritance tax. Here, youÂ’re truly king of the castle.Â
