I'd suggest you rely on the 08 series of FICO scores in general, or the 04 series if considering a mortgage.
Here's where to get them:
EX 08, EQ 08 - this site
TU 08 - Barclays, Discover, Walmart
EX 04 - PSECU
EQ 04 - DCU, Equifax site
The last item mentioned, the EQ 04 score from Equifax, is the best choice for mortgage contexts.
