129 Erwin St, Boonville, NY 13309

Spacious side-by-side duplex offering the feel of two full homes under one roof. Each unit features 4 bedrooms and a full bath, with the owner’s side expanded by a finished attic that includes two bonus rooms—perfect for a home office and dedicated movie room. This property has been owner-occupied, with one side used by the primary family and the other thoughtfully utilized as a private in-law suite—never operated as a traditional rental—showcasing pride of ownership throughout. Both units offer full walk-out basements, shared enclosed front and rear porches, and separate meters with utilities serviced by Boonville Municipal Power. The property sits on a large, fully fenced backyard. There is an oversized 4-car garage featuring loft storage—ideal for vehicles, hobbies, or additional workspace. Square footage per seller includes approximately 800 sq ft of finished attic space and an additional 800 sq ft of unfinished attic. The owner’s unit includes smart switches and individual programmable thermostats in every room for efficient comfort. Most windows have been upgraded to thermal replacements. Major improvements include a garage addition built approximately 10 years ago, a full roof replacement, and a completely rebuilt front porch just 4 years ago. Excellent flexibility for income potential—rent both units, or live in one while generating income from the other. A rare opportunity combining size, functionality, and long-term owner care.
