There doesn't seem to be enough information to support that.If you purchase a property but then spend 4 months rehabbing it before its first occupancy, your depreciation starts from the date it's placed in service (first occupied) not the purchase date.

I have called 20 banks and no one does a 1st lien on investment properties except 1 stated they would if owner occupied.During the research I read a website, which stated that 1st lien HELOCS on non-occupied are illegal and not allowed by Federal Law.Anyone know if this is true?

VA requires you to occupy the home as your primary residence. 

I want to occupy one of the units, my preference would be the 2/1 so I can collect more rent from the 3/2 to go towards my mortgage. 

I'd recommend owner occupied 2-3 flat for your first one.

This is an essential tool for anyone buying a tenant-occupied property.
