It looks like income tax is .55% (6.5% vs 7.05%) less than Minnesota.

Property taxes are about the same, but no homestead deduction as in Minnesota. Result - property taxes paid will be double what Minnesota charges. Since property value is half of current home, amount paid will be the same.

Since I'll still be working in Minn, i can make any purchases where ever I can find the better value. Sales tax in WI (St. Croix county) is 5.5% St. Paul MN is 7.0%

And I can get gas at the cheapest location.
