Thanks for everyone's input. I really appreciate it! Here's where I am now...
I contacted my loan consultant and asked for copies of both credit reports and my home appraisal, so I could review the documentation myself and try to determine what happened. The first report was run on 1/14/09 and they did use the wrong SSN, but everything on the report is my wife's and it even gives her correct SSN everywhere else on that report... Those scores were 710 (XPN), 706 (EFX) & 699 (TUC). The second credit report was run on 4/6/09 using the correct SSN, but again all the accounts, info, etc is the same except some fluctuations in the balances. These scores were 668 (XPN), 691 (EFX) & 703 (TUC). I'm assuming the middle scores are used as a sort of average??
Anyway, I went over these reports very carefully to see what could have caused the 15 point decline in score. The total revolving credit balances actually declined $72 from January to March. Most account balances went down, but one account went up about two thousand dollars. I've read that credit balances make up about 30% of your score, especially balances exceeding 20% of the cards limit. Since my overall revolving credit balance declined , would I be correct to assume that because this one card that I've used has gone from about 15% of the credit limit to about 24%, that this is the likely cause??? I've had some recent business travel expenses and an unexpected car repair charge that have all been put on that card as well, so it's gone up even further since 4/6/09. Since I absolutely loathe the idea of paying an extra $4-5,000 to my lender, I was thinking about putting that same amount of money towards this one card's balance to bring it back to where it was originally, hoping that this, along with the fact that all of my other balances are at similar or lower balances (none higher) than in 1/09, would raise my score back up enough to avoid the increased fee (ie, above 700).
I've got the cash, but I realize this is a bit of a gamble since I don't know exactly how the scores are actually calculated and I'd have to time the next credit check so that any new payments would be reflected on it. Also, I now have several credit inquiries that may adversely affect my score as well, which was also a concern raised by my loan consultant.
So there's my quandry: Do I gamble hoping to drop my debt and save the original deal I expected, but risk making things worse (more costly) or do I suck it up and pay the extra money to these guys and move on? (Walking away isn't much of an option for me since I've already paid $750 for appraisal, app fee, etc, so I'm committed to do something. I'm leaning towards paying down the one balance and hoping for the best, but wanted to get your expert opinions on the matter...
FYI: My current loan is a 30 yr fixed at 5.75%. A refi with a 30 yr fixed at 4.875% would drop my monthly by about $540. I think my break even on closing costs/points would be about 21 months at 2 points and 29 months at 3.125%.
Thanks again for any thoughts or insights!
