Moving to FL in 2 years, buy house now and rent?

[Jolene Perry]

My husband and I live in Iowa and plan to move to FL. in 2 years when his son graduates. I am thinking that with real estate still low down there it might make sense to buy house now and rent it out for 2 years? How do we determine what would be a financial model that would make this work? I'd obviously love to make money for the 2 years, but since it will eventually be our house, will a lower cash flow situation still make sense?
