^^When I moved in to my current place, the start-of-tenancy date got pushed back by a month because the previous tenant refused to leave. She cited some issues with getting a deposit together for a new place, due to breaking up with her partner. Why that should end up being my problem I don't know. But in summary, I think there are ways you can stay past your notice date. Not sure of the legal position though.
