not allowing winter move outs

[KENDRA J.]

Hi

One of our tenants has a one year lease that ended last month on a 1 bedroom condo he rents from us. Tenant has been a good renter who has paid on time so we are allowing him to go month to month. We do not want a Nov, Dec, Jan, Feb move out on this property but did not include that in the original lease. Would we have to have the tenant sign a new lease with those months excluded from moving out? Does anyone know if it is legal in the state of MN to not allow tenants to move out during winter months?
