Can you buy a home if you filed bankruptcy and foreclosure and when?

So my parents had to file bankruptcy and our home got foreclosed because of the 2008 whole real estate thing and foreclosure and economy crash. Our home got foreclosed and we had to move into a really small place (we have big family so its really cramp) since then.
So my question is when can my parents buy another house and get a loan? Can they work around it somehow?

Can I buy a house under my name for them now? I'm 21 now and work part time and still going to school (4 year college). I have a credit score of 740. I was thinking of if it were possible for me purchase a home under my name and my parents can pay for it. Im currently getting financial aid for college if I were to do that will I not be qualified for financial aid anymore?
Thanks!
