I am not too sure.

Because MI is not a community property state, your LLC is a partnership that has to report K1 form. 

https://www.irs.gov/pub/irs-pdf/f1065sk1.pdf

see box 2 (net rental property income/loss).  

So the 20K loss has to be divived between you and your husband and report on K1. 

Your husband's 10K cannot be deducted.

Check with a CPA, this is my understanding.
