polar25,
The way it worked for us, you had to provide a copy of your full Experian credit report to BBVA. Incidentally, it had to be from Experian, rather than any other credit report agency.
When I got mine, it initially had a lot of stuff missing, giving me a 'Fair' rating, which I got the impression would not have been acceptable to BBVA (they stated that really it should be in the green ranges, 'Good' or 'Excellent'). After speaking to Experian, all my details were properly updated and it thankfully increased to a far higher score.
I'm not sure what anyone else's experience was, but they seemed to expect a good to excellent rating at the time we were applying. I'd expect that that position is unlikely to have changed, but who knows. You do at least get to speak with an individual at BBVA about it, not just having it fired through a computer, so maybe there's room for discussing extenuating circumstances? Who knows.
