I wouldn't purchase any type of vehicle that didn't have a clear title in the name of the owner but still had a lien against it. If the current owner has a loan against the rig then that's his problem to first pay it off so he can then provide any potential purchaser with documentation proving any lien against it has been cleared. How you later fund the purchase, cash or otherwise, is your problem. Secondly, I'd also insist on 3rd party inspection, negotiating who pays for that inspection - seller or buyer - regardless, it would be foolish to buy something as complicated as a MH and not have it fully inspected.
