Investment Insights
Based on property information with market context.
161 Blackwater Road presents a single-level duplex with two independently leased units. Each unit offers 2 bedrooms and 1 bathroom, and the property includes on-site parking. The seller reports recent hot water heaters and heating systems that have been maintained very well. Current leasing includes one tenant on a month-to-month arrangement and the other on a 12-month lease.
The building sits on just over half an acre in Somersworth, New Hampshire. The property is being offered for sale and is described as a cash-flowing duplex. The reported NOI is just over $31K per year, with the seller noting the opportunity for it to exceed that figure.
This is a practical fit for investors seeking a small residential income asset with an established rental setup, or for an owner-occupant interested in a “house hack” structure supported by existing tenants. The mix of lease terms may appeal to buyers who want some flexibility while maintaining a longer-term tenant in place. For scheduling and access, please do not inquire within the premises.
