Please Help! Buying a Multi-Family and Owner Occupying

I need some help.

I am looking to buy a small multi family. The property is a duplex but can be converted into a 4 plex with a little bit of work. The duplex is currently occupied by tenants on a month to month lease. This will be my first property and I want to fund the deal through an FHA loan where I know I have to owner occupy which is my intentions. My question is with the tenants being month to month, can I just buy the property, not renew either leases and then renovate the property and convert it to a 4 plex while I'm living in it allowing me to qualify for an FHA loan? What are tenants rights in that type of situation in Utah?
