Exceptional Mixed-Use Investment Opportunity in South Portland
Rare opportunity to acquire a well-maintained, income-producing mixed-use property in a highly visible Main Street location. This versatile three-unit building offers a diversified income stream with a gross annual income of $70,800, anchored by an established medical office occupying the entire first floor, providing the benefit of stable commercial tenancy.
The two residential units above provide additional rental income and strong tenant appeal. Each residential unit features its own washer and dryer, while tenants are responsible for their own heat and electricity -- helping reduce owner expenses and maximize net operating income.
Meticulously cared for and truly turnkey, the property offers desirable amenities including off-street parking for up to three residential vehicles, additional on-street parking for tenants, clients, and guests, and convenient access to public transportation.
Ideally positioned along South Portland's Main Street corridor, this property is close to local businesses, shopping, dining, downtown Portland, major commuter routes, and area amenities. With proven rental history, strong tenant demand, diversified commercial and residential income, and excellent visibility, this is a rare opportunity to own a stable, cash-flowing investment property in one of Southern Maine's most desirable markets.
