Sole proprietorship for a rental while married

[John Carbone]

Looking to buy an investment property that will be rented out. This will be bought in my name (and spouse)  and rented out under a sole proprietorship. I want to keep my spouse separate from the business so I can just file as a sole proprietorship with all income going to me. Can she legally be on the mortgage/deed but not be involved in the business aspect of renting it?

I’m aware of benefits of doing llc, but I do not want to do that based on my situation. I need to be sole proprietorship 

thanks
