Property Description
Two charming cottages on a single parcel offer a rare and versatile opportunity in Sonoma Valley. The one residence features 2 bedrooms and 1 bath, while the second is a well-appointed 1 bedroom, 1 bath cottage. Each enjoys its own private yard, carport, and dedicated storage, with ample additional parking on site. Ideal for an owner-user seeking a private compound, a buyer looking to live in one home while generating income from the other, or as a pure investment propertythis offering benefits from consistent rental demand at this price point. Thoughtfully updated over the years, both homes are inviting and full of character. A truly uncommon find, as duplexes do come to market from time to time, but two detached cottages on one parcel are seldom available in Sonoma Valley. Tenant in 18343 pays $2100/month and tenant in 18345 pays $2300/month.
