I'm hoping someone can offer constructive advice. I checked my credit score on Feb. 28 prior to applying for a new HELOC to get a lower interest rate. My score was 770, as usual. I got a letter from the bank a week later agreeing to the loan but saying my EQ score was 100 points lower than it had been just the week before! Turns out someone had erroneously shown I'd closed a credit card account with a pretty high balance on it. Also, I'd paid the wrong amount on my current HELOC a couple of months ago, so it showed $109 past due. I paid it within 30 days and the bank corrected it with EQ. I also immediately paid the credit card down to about $2000, then finally got the credit card closure error corrected. By my reckoning, my score should be even higher than before, as all accounts are in good standing, and I have freed up about $15k worth of credit on the card. But my rating is only up 55 of the missing 100 points. Any thoughts on what I can do to get the other 45 points back? I've worked hard for them, and I feel I have no control over how to get 'em back.
