Yes there is, but there are things that you need to provide to the mortgage company for a rapid re score of your FICO score. If you see an item on your credit score that was reported in error, you need to contact the creditor to dispute that. If the creditor accepts the fact that the item was recorded in error, they will issue you a letter that they will correct it. Once you obtain that letter, you need to present it to your mortgage lender to have them re score your FICO. For example, I was able to re score a client of mine that had a 671 FICO, to a 700 FICO by re scoring him after he obtain the letter. It took him 15 days for the process and 72 hours for the re-score.
If the items that are reported negative are correct, then your going to have to establish more credit to off set that one item. If your looking for a more competitive mortgage rate, and depending on where you live. You might want to look at government programs and state bond programs. Hope this helps, e-mail me if you have any further questions.

Pay down or off any credit cards (if you cant afford to pay them all off, try to pay them down at least to be under 50% of your available credit limit), but do not close any accounts since your available balances affect your score. Ask your creditors to update this immediately (& not in 30 days as they would notmally) & this should push your scores up. If your score is over 720/740′s your get the best rate, if your over 680 you’ll be able to get excellent rates, & 660′s & up will still be ok – the score may o rmay not affect your interest, that will depend actually on the loan program your interested in (some programs are more credit score restrictive).

get some of your money (or ask a friend) for about $5000 (could be less) and ask the bank for a secured loan. Since they have your money as collateral there is no problem to issue the loan. Take the $5000 from the new loan and go to a second bank. Ask for a secured loan again. You start to see my point. Do that with 5 banks and pay everything back (with some interests) next month.
When you pay back one bank get your collateral back and go the next bank to pay the 2nd loan and so on.

no.
