Do you have to purchase all units in a fourplex?

[Paul Lee]

Theoretically, if there was a fourplex that was priced over the FHA max loan limit, would someone be able to use an FHA loan to owner-occupy and purchase 3-units as a "triplex" and then finance the last unit with an investment property 1-unit loan? If not, what would be some creative ways to finance a fourplex that is over the FHA max loan limit for the area? Thanks in advance!
