A 63-acre island estate in Connecticut is on sale with an asking price of $175 million.

Industry experts say that would easily break a record for the most ever paid for a residential property in the United States.

The property in Darien went on sale this week. It includes a stone mansion, a 21-stall horse stable and a natural cove that can shelter boats in stormy weather. Since around 1900, the property in Long Island Sound has belonged to the family and descendants of William Ziegler, an industrialist who made his fortune in baking powder.

Listing agent David Ogilvy said the family decided to sell the estate known as Great Island as younger generations have moved on. He says the main house has not been occupied for some time.
