Indeed, buying a private island is no longer just something for the rich and famous: The research shows that some islands cost less than a house. Today, the median home listing price in the US is around $245,000, according to Zillow. Sure, private islands that have luxury villas, private beaches and stunning views are expensive, but you can buy the 2.7-acre Round Island in Nova Scotia—in the waters of Lac d’en Bas—for a mere $58,647, while Half Island in Cape Breton, Nova Scotia, goes for the $59,024 and includes an Airstream camper shell in the purchase price. Located halfway between New York City and Albany along the Hudson River, the wooded Naomi Island costs $99,000 and is reachable only by boat.
