The tenant is also responsible for garbage service, building and septic maintenance, and lawn care/snow removal, resulting in minimal landlord responsibilities which are limited to roof, structure, parking lot and HVAC replacement (new HVAC currently being installed). Additional passive revenue is generated from two longterm rooftop cell tower leases with major telecommunications carriers, Verizon and T-Mobile, providing stable supplemental income with annual lease increases. The total reported net operated income for 2025 was $478,752 reflecting a cap rate of 7.37%. 2026 proforma NOI is $490,658 reflecting an increase to a 7.55% cap rate.

Recent capital improvements include a new HVAC system currently being installed by the landlord and a roof replacement completed two years ago, enhancing the property’s long-term reliability and minimizing deferred maintenance expense. Future expansion-Situated on a sizable parcel with potential for a 10000 sq ft building expansion subject to zoning approvals, the property offers future upside in addition to its existing income stream.
