If these were the last items listed on the negative side, it sounds like your reports are in pretty good shape, and FICO is grasping at straws! I've had the identical util percentage show up as good one month, bad the next, and then good again the third, all on the same bureau score. All that being said, under 10%, as in 9% or less, seems to be a scoring breakpoint.
With the two different util figures: are the balances on your EQ and TU reports identical? Do you have a line of credit or home equity line of credit? These sometimes get factored differently by the three bureaus.
* Credit is a wonderful servant, but a terrible master. * Who's the boss --you or your credit?
