Investment Insights
Based on property information with market context.
This new construction residence is designed for flexible living. The main home features a bright open-concept first floor with living, dining, and kitchen space flowing together, and an upstairs layout with three bedrooms including a spacious primary suite. For year-round comfort, the main home includes efficient forced hot air heating and central air conditioning. Above the attached two-car garage is a fully equipped two-bedroom apartment, providing a practical setup for multi-generational living, a private guest or office space, or a rental arrangement.
Set within a small, private neighborhood, the property is described as being moments from local schools and a short stroll from downtown amenities. The remarks also note quick access to the Maine Turnpike, supporting convenient commuting.
From a tenant and owner-operator standpoint, the apartment over garage arrangement creates clear separation while keeping both units under one roof. The main residence’s central living design and dedicated bedroom configuration can support comfortable everyday use, while the attached two-bedroom unit can serve extended family, guests, or an additional source of rental income, depending on how the property is operated.
