Your ability to purchase a home depends on many factors. Your credit score is just one of them. If you had enough cash, you could buy a home regardless of your credit score. If you need financing, you'll still need some minimum downpayment. The lower your credit score, the higher your downpayment would have to be or the higher your monthly payments would be. In theory, unless you had a credit score far below 500, you could get some form of conventional or government-backed financing. To know for sure, you'll have to work with a mortgage loan originator who can properly assess your current financial situation.
