Real estate tax benefits/drawbacks with my other household income

[NA NA]

My wife and I make a combined household income of approximately $400,000 from our 9-5 jobs.

I understand that certain tax benefits are eliminated or reduced after you cross higher ordinary income levels related to real estate.

What are some things to consider before getting in to real estate to take advantage of this?

Would putting the real estate in LLCs help?

Married filing separate with my lower earning spouse?

What are some strategies I should consider?

Thanks for all your help!
