ANZ has now joined with the other banks to implement changes to its ANZ low doc loans. This is in line with the responsible lending guidelines under the NCCP. Westpac has been for a long time requiring BAS statements on its low doc loans. CBA has just recently changed its lending criteria and low doc loans policy and now require BAS on all low doc loans irrespective of LVR. Suncorp also require BAS on all Suncorp low doc loans.
So in conclusion, the lending criteria for major banks is now changing rapidly, and BAS is now part of the landscape.
