1 - Owner Occupied, Non-Owner Occupied, OO Residence, OO 2nd Home
2. 1st lien, 2nd lien, AOC
3. Same as Cowboys Fan. We have four digit codes that define the collateral based on type, lien position, owner-occupied, etc.
I use some of the codes for reporting, but they aren't really used for call reporting at all.
Just a heads up, make sure that however you set them up, it will be right for the bank. I've had to change coding twice at banks and it's a pain, even if you can make it work with a Foxtrot run via ITI.
