Not meeting any one of the requirements, means you don't qualify to be claimed as a dependent on any one else's tax return. So that's not an issue now. Just had to check and be sure, because I see quite a lot of undergraduates who do qualify as a dependent on their parent's tax return, claiming they don't qualify as a dependent, just so they can get the stimulus. What they don't realize is that the IRS is going to audit them on this 24-36 months down the road, and they're going to lose on that front.
Now on a prelimiary (and not complete) read through of the requirements, it "looks" like you may be able to claim the homestead credit. But you really need to confirm this yourself by reading the qualification requirements on the Wisconsin Dept. of Revenue website at https://www.revenue.wi.gov/Pages/FAQS/ise-home.aspx
