Your renters are moving; you want to show your suite to prospects. First, try to agree with your renters on blocks of time, e.g. 2 to 5 hours, 3 to 4 days a week. Confirm the agreed times in writing or by e-mail. If no agreement is reached, give your renters written notice that you will restrict the showing to within 3 to 4 blocks of time per week. 24 hours after receiving it, the notice is effective for 30 days; you don’t have to inform them in advance of each showing.
