Will it make a difference in price if I go from 8′ ceiling in my new home to 9′ or 10′ ceilings?

Keep in mind when you change the height of a ceiling from 8’ to 9’ or 10’ that you will first of all add more framing costs in labor and material for the extra 1 or 2 feet you are adding.  This will also add more area outside the home to be bricked which will affect labor and material.  When you get to the finishing phase of the home, you are adding more drywall and paint labor and material.  Also a larger hvac unit may be required for the particular floor(s) you are adding the ceiling height.
