You'll find it very difficult to borrow with a 450 credit score, unless you're looking for a student loan. In particular, you're unlikely to qualify for a mortgage with a 450 credit score because FHA-backed home loans require a minimum score of 500. But your odds are a bit higher with other types of loans.
