I am purchasing an existing running business as a franchise from corporate. We are in the last few days of escrow and I found out that there is a substantial lien on it (business loan that corporate took out). Instead of assuming the loan, the broker and owner wants to continue the sell of the business with the liens attached. Owner is convinced that the business location being sold is not attached to the corporate loan in any way (but can’t explicitly prove it). The owner promises to pay off the business loan in 6 months. Is there any additional documentation I can/should have the owner sign to guarantee loans to be paid off within 6 months? Or is there a better way of going about this?
