If you are talking about the state law for anti-predatory lending, yes, it would generally supercede Reg Z. So in Illinois, it would apply to any loan not used to purchase the primary residence, and the APR trigger would drop to US Treasury + 6 percent for firsts and 8 percent for 2nds. Total points and fees is calculated the same way as Section 32, except you get a smaller margin - only 5 percent (actually it's the greater of 5 percent or $800) on your points & fees limit.
As to what points & fees are included, you can generally exclude things like the appraisal and credit report and flood determination, things you would exclude under 226.4(c), unless of course they are paid to an affiliate.
Isn't this fun? Now do it for the other 12 states that have similar - but not quite the same - laws.
