What the lessor can require if there is a sale or financing of the building?

Should the building be sold, the standard lease normally requires that the lessee releases the lessor from any responsibility and that the lease is in compliance with the terms of any deed of hypothec signed by the new owner. It is also appropriate to require, before agreeing to such provisions, that the new owner make at first a commitment, in return, to respect all the obligations contained in the lease of the lessee.
