Had you mailed the disclosure it would have been 7 days.
If the revised ETIL is mailed you can close on the 6th business day after it's mailed.
Initial ETIL - you can close on the 7th business day whether provided face to face or mailed.
Revised ETIL - Face to Face you can close on the 3rd business day. Mailed - you can close on the 6th business day. HOWEVER, the 3 and 6 business day is dependent on the the original 7 business days having expired. If you issue a revised ETIL face to face on day 2 of the original 7 business days waiting peroid you would have to wait for the 7 days to expire before you could close.
