Martha's Vineyard features highly exclusive private beaches accessible only to those who purchase a "key," which is essentially a deed to a small, unbuildable sliver of land. These keys, which grant access to the entire private beach, can cost up to $400,000, and current listings show prices around $315,000. These private beach associations, unlike traditional beach clubs, involve members owning real estate, with beach key prices ranging from $100,000 to $300,000 for premium locations like Hancock, Black Point, and Quansoo beaches.
The value of these beach keys has significantly increased over time. What cost $2,000 fifty years ago at Hancock Beach was listed for $500,000 in 2012, and a similar lot sold for $465,000 in April of that year. Even in the early 1980s, keys were under $10,000, but real estate booms in the mid-to-late '80s and '90s caused prices to soar, with values climbing over $50,000 in just two years at one point. In 2017, a Quansoo Beach lot sold for $290,000. This dramatic price increase reflects the limited supply and high demand for these exclusive coastal properties.
Key beaches are desirable due to their exclusivity, uncrowded nature, and the social circle often shared by members. They offer a no-frills experience with no lifeguards or bathhouses, emphasizing natural beauty and privacy. While some, like Selectman John Alley, note that people enjoy the status symbol, local real estate attorney Kathryn Ham states that a key coming on the market would sell "about a day." This high demand is driven by the fact that "they're not making any more beachfront," as real estate agent Julie Flanders explains, making water access and privacy increasingly scarce and valuable commodities. The total value of an association like Quansoo Beach, spanning about one mile, is estimated at $15 million, highlighting the significant financial stakes involved in these private beach properties. Access to these beaches is often controlled by physical keys to gates, with beach associations charging annual fees.
