My mom and I are going to buy a house together. I asked her with the plan of taking out a mortgage for half. She decided she wants to buy it outright with cash and gets very upset with me if I mention that I should get a mortgage (I don't have much cash left after the down payment). I can understand why she would want to do this, but are there any legal issue or tax (neither of us itemize) to watch out for. We don't want to set it up as a loan, but I will in effect pay her 'rent', but my name will be listed on the deed as a co-owner.
