Check your state laws to see whether you have anything similar to what I have in WA State.
There is a section in the WA LL-Tenant Act that allows a tenant who lives alone to designate in writing a person to act for the tenant in the event of the tenant's death. This allows the LL to allow that designated person to access the tenant's dwelling unit, remove the tenant's property, receive refunds of amounts due to the tenant, and dispose of the tenant's property consistent with the tenant's last will and testament and any applicable intestate succession law. This speeds things up for the LL.
