Today my landlord informed me that
that next year’s resident has scheduled an appointment to tour the apartment for Thursday May 28th, 2020 at 12:00pm
emphasis added by me.
Here is the quote from my lease:
ENTRY BY LANDLORD. Landlord or its agents may enter the Premises in an emergency or to perform repairs, maintenance, code inspections, appraisals, insurance inspections, or for other purposes reasonably related to the operation of the building and to show the Premises for sale or lease. Except for entry during an actual or apparent emergency, all entries shall be made during reasonable hours; and Landlord shall make reasonable efforts to inform Tenants of its intention to enter and shall attempt to establish a mutually acceptable time.
My residence is in Michigan. This stack exchange post lists the requirements for entry. I interpret this case, however, as not a prospective tenant but a confirmed tenant i.e. they are already legally bound, unless they break the lease, and are no longer a prospective tenant.
Finally, this is also during the COVID-19 lockdown so I have no where to go during this time. The landlord did inform me that they would wear facemasks while entering the apartment but I just don't feel safe having strangers enter my apartment for no good reason.
Therefore, can I reasonably refuse them entry if they have already "sold/leased" the apartment?
