I cannot give you an exact time frame as to how long it would take to increase your credit score, but I do know that a mortgage broker can run your score free of charge provided you eventually work with that broker. The score include all three bureaus which will indicate what steps you'll need to take in order to raise your score to 680 asap. You can also to credit.com and pay a fee and run your score yourself and determine what you need to do. That choice is yours! If you need to be in contact with a good mortgage broker that can help you get a home through various low down payment programs, call me @ 954-557-3416 and I'll be glad to give you his contact info.
