Few would argue that significant strides have been made in the quality of construction, wind resistance and aesthetic appeal of modern manufactured home.  Energy efficiency is also a major priority on these homes with insulation in the attic, before the roof is attached and in the walls.  Buyers who are looking for affordability often overlook the ENERGY EFFICIENT UPGRADES.  Tested Energy Star certified manufactured homes add about $8 per month to the typical mortgage while saving an average of $30 per month on heating and cooling bills.  All of this from Harold D. Hunt at the TX A&M Real Estate Center.
