Duplex, End of tenancy lease question

[Jonathan Kahnke]

Hello Bigger Pockets Community,

    I have recently acquired a large residential home split into a top and bottom floor units. I would like to move into the top floor and have the bottom floor rented out. I was wondering if there was anything required to do to let the top floor tenant know that they cannot release. This tenants existing lease that came with the property ends next march 2021. I also currently live in the state of Wisconsin, USA.
