Very unique ranch home in Princeton Township. There is plenty of room in this ranch. Master bedroom could be divided into two rooms very easily (separate doors already in place), fireplace in living room, small second bedroom, large dining room (presently has two beds in it), huge kitchen with skylight, and gorgeous heated sunroom off the kitchen. The basement is finished with built-in bar and full kitchen. There is also a full bath in the basement too. 1 car garage and 1 car carport are attached to the home. Alarm system, central air and gas forced hot air heat. Very interesting home with a separate workshop in the basement too. The back yard is very nicely landscaped with 2 sheds included. Come use your imagination to make this your dream home. The home is in very good condition but needs some updating.
