IMHO, that is something the regulators would likely look at, especially if the neighborhood is not representative of all racial and ethnic groups. (Think redlining - think of the effects test). With the way the DOJ, CFPB and all other regulators are looking at lenders, the next question would be, why is that only in XXX tracts and not in the majority minority census tracts.
