owner occupied or non owner occupied

[Tom Server]

I'm purchasing a triplex which currently has tenants in all the units. I need to apply for a mortgage loan.  I plan on living in one of the units, but what happens if I cant evicted in time of the closing? Do I need to apply for a non own occupied loan instead?  Should I still apply for the loan and put the address of the unit I plan on living, even if it takes a few months?
