Get divorced?
Ask your accountant about it.
Other than generously allocating expenses thru the llc not a lot one can do outside of specialized real estate that carry tax deductability incentives.
Idk if a non llc with the wife as a RE professional on the joint return would help any. Would carry large PL rider in this case.
If the wife has a W2 income in addition to RE activities it limits this option.
A cpa is good. A cpa that is a tax attorney is a better place to be. Good luck.
