Your own private Island for $65,000
The listing claims that the Island already has power available to it, and all the amenities of comfortable living are said to be close by. The listing also indicates that multiple anchorage points make the island ideal for development. Personally, I'd keep the whole darn thing to myself.
Considering that 40 acres of undeveloped real estate here in Northern Wisconsin can cost well in excess of $40,000, I think that just $65,000 for a private island is pretty darn cheap. In fact, the people who can afford the yacht to get back and forth from an island on a regular basis would probably consider this price mere chump change.
