Have you ever wanted to own a home in a seaside town next to a golf course? This duplex in Castine is the perfect setting for you to enjoy all that the Penobscot Bay and Blue Hill Peninsula region has to offer. This duplex has been a great family home as well as an excellent Maine Maritime Academy student (or faculty/staff) rental in the fall/winter/spring - and AirBnB short term rental in the summer. The 2 bedroom front unit has many updates (make sure to take the 3D Tour!) and the back unit built in the 1980s has 2 bedrooms upstairs, and 2 bedrooms down. A wonderful opportunity to live on neck, and have the second unit assist in paying the bills. Full Home Inspection Report will be available by end of July 2020.
