Dealing with Tenant Abandoned items in Garages

[Gordon Olson]

I live in Minneapolis and am looking to house hack for my 1st property ever! My concern is, if I buy a duplex 1)am I required to allow usage of a garage on one side and 2) in the case a tenant leaves without removing their belongings from the garage do I have to hang onto it?

If I specify in the lease that any leftover items will be discarded of the day after moving am I allowed to do that in MN? I want to avoid having to put the tenant's stuff in storage and paying storage fees, etc. I'm also concerned that even if that is the case I would continually wind up getting stuck with paying to dispose of tenant's stuff.

Can I charge a monthly rental fee for the garage as well even if it's already attached to the property? I mostly want to buy a duplex in a way where if tenants leave I won't get stuck paying to store or dispose of their stuff. Thanks.
