All 7 units are currently occupied, generating approximately $124,200 in gross annual rental income. With low annual operating expenses of approximately $20,089, the property produces an estimated $104,111 in net operating income before debt service, making this a compelling addition to an investor's portfolio.

The property also includes an approximately 1,600-square-foot hangar building and a 300-square-foot storage container, further diversifying the rental income. On-site well and septic help keep operating expenses low. With all 7 units occupied and income already in place, investors can benefit from immediate cash flow without the initial lease-up typically associated with multi-tenant industrial properties. A rare opportunity to acquire a fully leased, multi-tenant industrial investment in one of South Jersey's desirable industrial locations.
