Your current tenants intentions may be good but things still can go wrong with closings. set aside the early termination and think about it, EG you have a tenant who is not happy and they send to you proper notice to move out so they dont renew , You begin showing and even get a new customer with signed lease . Current tenant finds a new place last day of current tenants occupancy they learn that the place they were going to move into will not be ready for 5 days , the current tenant refuses to leave, Its a civil matter now. You have very unhappy new tenant who insist on being refunded what they paid you ,when you could not deliver, bottom line if they took you to court for failing to refund them and end your lease with them because you did not deliver on date lease promised them one empty unit they found a place that was empty You lose. Same thing happens all the time with tenants who are given notice by a LL to get out . so you reduce the risk to your self of being on the spot with a new customer, not new customers fault. Not your fault. Your current lease with current tenant is valid current tenant cannot get out of paying you for the last two months of this lease so if something blows up on them with the closing or delivery to them for the new house dont make it bigger problem , show the unit if you have fees for screening & application yes you can collect them but available date will be left open = soon as its empty and presentable.
