Would this duplex be considered rental or owner-occupied? (loan, property, Texas)

[joyfincher]

I live in Texas, and I am looking to buy a two-sided duplex. I want to let my daughter live in one side and the other side has currently been rented for two years. I would like to put the duplex in my daughter's name and co-sign for her since she is a college student and only has a part-time job. Would this be looked at as rental or investment property where I have to put 20%-25% down or would it be looked at as owner-occupied where I can put down 3.5% on an FHA loan?
