In practice this means the buyer inherits the same landlord obligations you currently have, including the notice period required before showings and the terms of the existing lease itself. Some buyers factor the tenancy into their offer, others walk away because they specifically want vacant possession.
The listing has to be marketed with the tenancy disclosed upfront, since a buyer who discovers an existing lease after making an offer can walk away or renegotiate, and either outcome costs you time.
Being upfront about the tenancy from the first showing keeps the right buyers in the process. Get your hand-reviewed valuation from Joel Dyck.
