And I'm not talking about a HELOC on top of a regular mortgage, but a HELOC instead of a mortgage. 

Not jewelry, Computers, Guns, iPhone's, Dental Services, ….. just shipping and paper services.Now, one half of the building will be empty in about 40 days, so there will be a totally empty 1000 sq. ft. very nice open room / office available.
