The way we do it here is: if the property is all on one tax lot and there are more than 5 units, it is considered all one multi-family property.
There is one loan #, one piece of property, one tax lot.
But, I would check into the way your FI usually reports a situation like this and be consistent. You don't want to change the way things are usually done there just to be able to report this for CD. Another option, (if possible) ask your regulator how they want to see this reported. It really does come down to how he or she will look at it.
IMO, as long as this project really is going to be affordable housing, I'd report the loan both for HMDA and as a CD loan for affordable multi-family housing.
Any other opinions out there?
