Investment Insights
Based on property information with market context.
This turnkey duplex features two units, each with two bedrooms and one bathroom. Unit interiors include granite counters, tile and wood flooring, and high-speed internet capability. Appliances include a gas cooktop, microwave, refrigerator, and gas water heater. Both units are climate controlled with central HVAC (natural gas heat and central air, with electric cooling). The property’s exterior and major systems were updated in 2018, including updated windows, exterior paint, a composition roof, water heaters, and updated HVAC units, along with significant interior upgrades such as fresh paint, refinished wood floors, stone countertops, and updated bathrooms.
The two units are leased with terms through late 2026 and early 2027. The home was built in 1942 and sits on a 0.163-acre lot with public water and public sewer. Parking includes driveway parking, a spacious two-car detached garage structure that could be converted to an accessory dwelling unit (ADU), and an additional one-car detached garage with storage.
With a combined layout of four bedrooms and two bathrooms, this property offers a practical setup for tenants who want independent living space while retaining additional outbuilding and storage options.
