Not meaning to gang up, Fran, but if talking to the landlord is a non-starter, you need to forget about this. As Mike just said above me, you’re going to be dealing with the landlord for the next few years, much more than the seller. The seller just has the stuff; the landlord has the roof over the stuff.
Does the landlord have a lien on the equipment?
Does the county have a lien on anything?
Again…stop. Deep breath. Landlord. Inspectors. Lawyer. Health Dept. Accountant (for a business plan, too).
Do NOT give the seller any money until you’ve talked to all of the above folks, and EVERYTHING shapes up OK.
If you really want to get rid of your money right now, I’ll be glad to take it off your hands.
