I can see your point of view Scott. However, where this might not suit you is if you sold a tenanted investment commercial property where you're the landlord and the new purchasing lessor wants to hold you over as guarantor until the end of the current 5 year lease in case the investment doesn't perform as well as you said.

The owner of the building doesn't put the obligation that they provide any guarantee over the tenant to a buyer of the premises, that is the purchaser's risk in due diligence. The vendor's obligation is simply to procure new guarantees from the tenant in favour of the purchaser/transfer any bond held on the building. That is not the assignment of lease but a transfer of title and all lesser titles and restrictions on the land. The matter that you've raised would be in the conditions of contract if that's what the freehold buyers negotiate such a clause ie a rent guarantee.
The op owns the building and his tenant is assigning the leasehold not the freehold. ie your second point.
