I now live in a small house on my mom's property but while it was being built I lived in her house. I did have a separate address (which I think (not positive) you can establish by having an Apt. A or whatever) but her income did not affect my Medicaid. I wasn't on food stamps or anything else (I have SSDI but that doesn't change) but Medicaid was fine with it. I did call and check.

I hope it works out for you. It has been good for us. She's there to help with the things that are too hard for me to do/do well enough and I can help her sometimes as well as she gets older. We're both happy this way. I won't lie, we both sometimes miss when I lived in my old house in another town, but mostly it is good. We took a while to figure out how to make it work but it does.
