Living in your own 5+ unit property

[Lance Friesz]

This could be an extremely novice question, but my wife an I are living in the Bay Area and looking to buy a home. Both of us have wanted to invest in Multi-Family unites and thought this might be a great time to invest, especially if we can live in one of the unites. 

This is where my questions is, would we be able to purchase a 5+ unit property on a commercial loan and live on the property? I am not sure if this is enough info, but it is my first question on there!
