If the intention is that the person running the business is also the tenant, then you should always make sure that the legal responsibilities of the lease are properly transferred for this to be the case. Sublets are different from commercial leases. In case of subletting, the seller retains his responsibility for the master lease he has with his owner. At the same time, the seller would enter into another lease with the person who will buy his store. Thus, an under rent would be in this situation. The lessor should, however, allow the seller to be sublet, as the master lease has more legal value. If the master lease had a clause prohibiting any type of sublease, then the seller would not be able to do so. .
