Charming Craftsman duplex, conveniently located in Southwest Berkeley. Both two bedrooms, one bathroom units are VACANT, have in-unit laundry, and bright, efficient living spaces. The large semi-finished attic space has great potential as additional living space or storage, and a detached backyard studio is perfect for working from home. The lovely shared outdoor spaces are surrounded by cherry, apple, citrus and persimmon trees, and mature, flowering vines. With an 86 Walk Score® and 100 Bike Score, this home is conveniently located between University and Ashby Ave, close to the 4th Street shopping district, I-80 Freeway, the Berkeley Marina, public transportation, parks, schools, and more. This delightful duplex would make a great home or investment property (or both!). Although vacant now, both units had been continuously rented since late 2015 at $2,495 or higher - great income potential!
