We require 620 credit scores so we cannot help directly. All parties on a loan need to meet the minimum credit score requirement, not just one of you. I do know there are lenders that will do loans down to a 580 score. But the terms and down payment may be higher. It may be worth it for you to take the time to raise your score to 620 to get the best terms. I think you need to find an experienced lender, well reviewed, who earns your trust, and go through a pre-approval process to see exactly what you can do now with your current score, and then ask what they could do if your score was 620, and you can decide if you think its worth waiting. But a lot of times there are things on your credit report that got your score so low in the first place, like collections, judgments, liens, etc; that may have to be resolved with any lender, even one who will accept a score as low as yours. So waiting may end up being your best choice for several reasons. Good luck.
