Many people start to dream about owning Martha's Vineyard real estate during one of their vacations to the island. Being on the island has such a sense of "getting away" from it all and the beauty of the beaches, the charm of the architecture and relaxing scenery cause folks to pick up real estate flyers at local stores.
Obviously, the Vineyard is a "destination location", attracting many tourists annually and it has limited geographical boundaries. These aspects, and others, push the prices of real estate into the upper ranges compared to most other areas.
