Can I rent out all my units using FHA after 1 year?

[Phillip Repalone]

I was under the impression that when buying a duplex using an FHA loan, it needs to be owner occupied for atleast one year before you can rent each unit. But I just heard that with an FHA loan you can never rent out all units. Can somebody please clear this up for me? Also while using an FHA loan, can I immediately rent out one unit? Thank you!
