Milwaukee Lease length

[Kevin Auyong]

I've had a few tenants whose leases ended in Nov or Dec which was a bad time to try to get new tenants.

Going forward I wanted to end leases in Feb rather than those months to avoid those months so maybe something like Dec 2020 to Feb 28, 2021 so that would be a 15 month lease.

My Property manager told me that was illegal and no lease could be longer than a year.
Is this true?
