Help me buy a home of my own

I've been working like crazy and still don't have anything towards a home of my own. I take care of my grandmother and aunt part-time. They have to move out of their place of residence because of reduced income. I would like a home for all of us, somewhere we could live comfortably. I live in California and the housing market here is so high but I haven't lost hope that someone, some where will help us with this situation.
