Lease Termination

I am living in a rented house in Wisconsin. This tenancy is a tenancy at will, and I am thinking of leaving this house. Can a tenant terminate a tenancy at will or is only the landlord who has the right to terminate a tenancy at will?

I live in a rented house in Wisconsin. I have a monthly tenancy agreement with the landlord. I have not been able to pay my rent this month. Can my landlord terminate the rental agreement?

I am living in a rented house in New York. Per the mutual agreement between me and my landlord, I rented the house on a monthly basis. Can my landlord remove me from the rental premises for occupying the rented house beyond the duration agreed between me and my landlord?

Recently I shifted to a rented house in New York. The rental agreement of this house does not state the time until which I can occupy the house. In such a situation, when will the tenancy expire?

I have rented my house in New York to a family. I had made some repairs in the building recently and got some new electrical appliances for the tenants. Due to some glitch in the new electrical appliances, the kitchen caught fire and got damaged. Now my tenant wants to quit the rental premises and shift to a new house. Can my tenant quit the premises in such a situation?
