A rare opportunity to own a fully remodeled fourplex just steps from Sonoma Plazacombining strong existing income, immediate upside, and the flexibility to enjoy part of the property yourself. Located at 528 3rd St W in Sonoma, this stunning 4 Unit multifamily property sits on a generous 9,300 sq ft lot and includes four spacious 2-bedroom, 1-bath residences. Three of the four units are currently leased and producing approximately $102,000 in annual rental income, while the fourth unit is ready for the next owner to decide how best to maximize the opportunity. All units have been beautifully remodeled. The flexibility of having one available unit to new ownership makes this offering especially unique for an investor, second-home buyer, or anyone looking to combine lifestyle and real estate ownership. Each residence has been thoughtfully remodeled with quartz countertops, stainless steel appliances, gas ranges, engineered white oak flooring, split HVAC systems, designer blinds, and modern finishes throughout. Ground-floor units feature private patios, and every residence includes designated covered parking. The property also offers a shared laundry facility with convenient app-based payment and separate metering for utilities and water, helping simplify management and operating expenses. The location is equally compelling. Just a short walk from historic Sonoma Plaza, residents have easy access to restaurants, cafs, shopping, entertainment, and everything that makes downtown Sonoma such a desirable place to live. 528 3rd St W is more than an income property, it is a rare Sonoma asset offering immediate cash flow, additional income potential, and the opportunity to personally enjoy a piece of Wine Country. Fill the fourth unit and maximize the property's revenue, or keep it for yourself as a luxury Sonoma retreat. Either way, this is a truly special property to own.

The ez Mortgage Calculator is for educational purposes only. Real-world interest rates and payments can differ due to factors like market trends, location, and loan specifics. Calculations are based on your inputs and might not consider extra costs a lender may add, such as insurance, taxes, and fees; thus, actual repayments could surpass estimates.
