Is it unethical to (legally) kick out good tenants?

[Darius Lipsey]

I'm using an FHA loan to purchase a small multifamily as a primary residence. I have found a property that is currently 100% leased to month to month tenants. I am buying a property as my primary residence and know that I have to occupy the residence within 60 days of purchase. Is it unethical to buy a property and legally kick otherwise decent tenants out to occupy the residence?
