Oregon's 90 day notice rule and FHA 60 days rule.. what to do?

[Ellie Narie]

Oregon has a law that says that if tenants have lived more than 1 year, you have to give them a 90 day notice. But FHA requires me to occupy home within 60 days. What do I do? About to make a deal on a triplex with FHA.

I heard about cash-for-keys, but what if the tenant will not accept this and wait the entire 90 days? I don't want to commit mortgage fraud because of the oregon law. Do I need to add some kind of addendum to the purchase contract that says that the seller has to give a notice to one of the tenants after acceptance of contract?
