Two custom homes for the price of one, with the front home appearing like a classic Victorian charmer and a separate contemporary house behind, both offering immense future value in the best location in the city. The main house (street side) originally built in 1897 was completely rebuilt in the 2000s with sustainable materials, energy efficiency, and a terrific curb appeal. The home fits beautifully into the classic Victorian Mapleton style with a covered front porch, custom detailed trim, and multiple artistic stained-glass windows. With a quality kitchen, a custom circular staircase, an upper-level bedroom with a huge deck, and a main-floor bedroom, both with private baths, the possibilities are endless. 2 bedrooms with room to add a 3rd bedroom. The secondary home (in the back) is a nicely updated addition featuring a bright living room with a wood-burning fireplace, granite and maple kitchen with ample storage, dining space, and a cute patio with access to the back yard. Upstairs, you'll find two bedrooms, one with a private deck, and a full bath with a jacuzzi tub. The basement offers a separate living, dining, bedroom, bathroom, and laundry. The back house also has a separate entry by way of the sizable yard with gardening beds. 2-car garage, storage beneath, and alley parking. OWNER FINANCING option depending on terms.
