There's a renter's credit in Wisconsin, but the first criteria is that I must be a resident. For the purposes of taxes, I'm not. There are other criteria that disqualify me as well. I guess I was hoping to find others with similar experience to learn if/how they manage similar situations, tax-wise.
Regarding finding a job in each-other's home state ... that is our intention and the arrangement we have now will not continue indefinitely. For more that a decade, we both lived in the same place (walking/biking distance to work for both too) until the jobs became intolerable. Unfortunately, the financial benefits of the current living arrangement are good. Obviously, we'd prefer to be in the same place, but we're making it work for now.
