There are duplexes, and then there are properties you remember. This one has a 33x33-foot reason you won't forget it. Hidden away on the third floor of Unit 1636, accessed through an entrance that feels suspiciously like a secret closet door, is an enormous vaulted loft unlike almost anything you'll find in a traditional 1908 home. The soaring ceilings and wide-open footprint create more than 1,000 square feet of space with possibilities ranging from creative studio to entertainment space, home office, recreation area, or simply one spectacular bonus room. The rest of Unit 1636 carries plenty of character of its own, with original hardwood floors, beautiful period trim and moldings, a main-floor half bath, and current rent of $2,180 per month. Next door, Unit 1638 generates another $1,700 per month. The property also features a premium Owens Corning 25-year roof installed in 2019, a newer detached 2-car garage, parking for two additional vehicles, and generous open-rafter storage. Recently price improved, this is a rare combination of cash flow, historic character, and a floor plan with a genuine wildcard upstairs.
