So here's the deal:

I'm a bartender in California. Because a certain amount of my income is under the table when I went to buy a condo this year I couldnt qualify. To counter this my mother bought the condo in her name as an owner occupied property. I live in it and pay the full mortgage.

So here is the basis of my question, is there a way we can both write off a portion of the interest? If so how do we go about that without risking audit? Thanks.
