The small creditor exemption criteria differ slightly for various rules, so you'll need to look at each one to see if you qualify. Just because you do or do not meet the Reg Z escrow small creditor exemption does not mean you will or will not meet other exemptions for "small creditors" (and whether or not you choose to take the exemption has no bearing on the others).
Heck, the QM small creditor exemption is still being written, so we have yet to see how that plays out!!
Me, Type A? Maybe - I'm not done analyzing it yet.
