Everyone has great suggestions...I would also suggest "local awareness"...If you are considering a rental strategy, use somethiing like www.rentometer.com, enter the sizes and address and see what THAT neighborhood is renting for.The other thing to do is establish a relationship with an investor friendly Realtor that can run a comparative market analysis for you to establish a resale value.
