Private island
Southeast Asia has numerous islands, with Indonesia being an archipelago of 17,000 islands and the Philippines having around 7,100. Real estate laws restrict foreigners' ability to buy property in the geographical area, and many islands either have unclear ownership rights or are already settled. Private islands that are available in Southeast Asia's real estate market are also prohibitively costly due to being in high demand by hotel developers. Developments address these difficulties by selling private islands that have villas and neighbor islands that have high-end hotels; the proximity keeps costs of habitation down.
