About this home
Very cute 2 bedroom 2 bath half duplex with a beautiful family room with a fire place. There is also a large screened in porch for extra outdoor living space. The kitchen and hall bath have been totally remodeled. This home has been an annual rental but would also be a great vacation rental.
