Agents help people buy, sell, and rent properties. These individuals work for brokers. Brokers, on the other hand, can work on their own, set their own hours, and hire agents to work for them.

Can you buy a private island? Yes. In most cases, you will need a deposit of 10 percent of the purchase price to enter into an agreement of sale. You will also need to arrange for a jumbo mortgage or private financing to cover the remainder of the purchase amount.

There are tens of thousands of private islands in the world, ranging from a few dozen square feet to hundreds of square miles. Usually, they are governed by the laws of a nearby country but restricted to use by the owner alone.

The majority of American private islands properties are located near the eastern seaboard, especially in Maine, New York and Florida.
