Investment Insights
Based on property information with market context.
This three-unit residential income property features a unit mix of one spacious multi-level 3-bedroom, 1.5-bath home, along with a 2-bedroom, 1-bath unit and a 1-bedroom, 1-bath unit. The property has been recently updated with a new roof and a new deck. Ample off-street parking is available with a six-car lot. With all three units currently rented, the building is positioned for immediate occupancy and potential future owner-occupancy plans.
The property is located on a quiet dead-end street and is described as being just minutes from downtown Biddeford, providing convenient access to local shops, restaurants, and everyday amenities. The address is 50 Mason Street in Biddeford, Maine.
For tenants, the layout offers a mix of bedroom sizes across the three units, including a larger multi-level option and two smaller configurations. For buyers, the fully rented status supports an income-producing approach, while the current setup can also accommodate future owner-occupancy, depending on how the new owner chooses to use one of the units. Recent exterior improvements, including the new roof and deck, provide additional operational confidence for an owner considering long-term management or transition to an owner-occupied arrangement.
