You appear to have the flexibility for a multi family, but do YOU want the big yard & pool, et al? That is only a question you can answer.
Be careful about doing a MULTI owner occupied Brrrrrrr... R.

Personal call. I personally believe that primary residences generally aren't true investments, it's more of a luxury. If you rented out the other rooms to subsidize your rent then I would count that as closer to an investment property.
