I just bought a House through relocation company.
Usually, When you make an offer to the owners, you submit the offer to them, they in turn, have their relo company draw up an identical contract, so you deal with the relo company, not the owner. BUT, the owner is on the hook for home inspection, appraisal, termite inspection, etc. Of course you make the offer contingent on home inspection and you ask for a credit at closing for things found wrong or ask them to fix them.
My inspection found about 2K worth of stuff to fix, they fixed probably $500 worth, credited me $500 and the other 1K was for the furnace and I let slide it since they had documentation , that it had been recently serviced. it was a PITA to deal with a relo company, but we got er done
Just ask, worst they can say is no!
