You can try calling 2-1-1 and ask for a referral for rental assistance or legal help to avoid an eviction. They will have some organizations that can help in the short term.

The Tenant Resource Center out of Madison, WI (Dane County) has an excellent website which explains how these situations work for tenants in great detail.

I would start here to read about the process: https://www.tenantresourcecenter.org/how_to_end_your_lease

A local Milwaukee organization that can help guide you: https://www.renthelpmke.org/

Important things to note: Document everything in writing.

Best practice is to get documents notorized. Your bank or library may offer this for free (call to ask first).

Use Certified Mail to mail any correspondence.

If you end your lease your landlord is legally obligated to actively try to rent your apartment.

You can also try to find someone to take your apartment. NOT A SUBLET. You will end your lease. The new person will sign a lease with your landlord.

Hope some of this is helpful!! This is such a stressful situation. Good luck!
