This Duplex has endless possibilities. You can keep it as a duplex or easily convert it back to a single family home. The first unit has a really cool loft space that can be used as a bedroom, playroom, office or art studio, just use your imagination. The large bathroom may be able to accommodate both washer and dryer. The 2nd unit has a large bedroom and living area. The 2 car detached garage is an added bonus. The back yard is cute but small. This will keep the yard work down to a minimum. Another great amenity is central air.
