Depending on your income NC has a lot of first time home buyers down payment assistance programs that you may qualify for and they pretty much forgive the credit score.
first thing to do is to talk to a morgage broker to explain your situation and take a look at what you can qualify for.

Mortgage broker who can review your file and parents file financial records, credit scores, debt ratio, income, employment history. Loan officer can determine if your parent can go sign what program you can qualify for. Keep in mind either you or your parents will receive annual tax benefits.

Another option where your parent purchase a home you pay them rent, at least you keep in your family investment property vs. a stranger who is getting rich off your monthly rental payments.
