You have a duty to be efficient, otherwise he could claim that it took 73+ days to rent simply because you dragged your feet after receiving his move out notice.Read your own lease, and if the tenant is required by your lease to cover the costs, I would inform the tenant, also in writing, that you "accept the offer of 2 months rent, in advance, as escrow for breach", and that "tenant shall be responsible for any additional re-rental costs; tenant shall receive a pro-rated refund if the unit is re-rented in less than 2 months."
