The two previous answers you've received are correct, but do not help you at all.
You have to raise your credit score. Fast. The truth is 6 months was too short. You need to extend the time on your option and get to work on raising your scores. You should have a current report from each of the big three, and be sending them all monthly letters challenging the negative items on all the reports. You need to do this every month to each of the reporting companies for at least six month straight. You can do this yourself. But, if you know that you won't, call me and I'll give you the name of a company that can help. Charles Hite 916-798-5009
