I have also received instructions from our regulator that if the facility is a line of credit, be it commercial or HELOC, it is optional to report.
If you have a customer with a commercial revolving line of credit, and the customer uses that revolver to purchase and re-hab properties, then IMHO you would only report the line at inception and if you renew with a "new obligation" AND only if you also report your HELOCS.
However, a "Guidance Line" may simply be a pre-approved credit limit under which additional loans are advanced. In that instance you would report each individual loan. The trick is figuring out the "application date". You may want to set up a formal "request form" process so that you have a documented date for the file.
