see the Commentary to Section 226.3:

When I go to this link - is it correct that the effective date is 7/1/2010? I thought this response was in regard to the new early TIL Reg. Z changes which go into effect 7/30/2009? Would someone please check this out? Thank you.

There are changes to this section which will take effect July 1, 2010 which you can get to by clicking on the blue link on that page. The text on the page you gave us the link for is for the current version of the Exempt Transaction rule, which is what you look to in order to figure out which rental property and investment property related loans are covered by Reg Z, among other things.

For purposes of determining when a loan is covered and potentially subject to early disclosures, the changes in 226.3 don't have an impact.
