Insulation
One of the best investments you can make is to insulate your house. As energy prices rise, this investment pays back more rapidly.
The best expert I know in the field of home insulation is Doug Rye, the "caulk and talk" guy. He has a popular regional radio show in Arkansas.
He has been working on this for 40 years. He can show you ways to save a lot of money on your heating and cooling bills.
If I ever build a house, it will conform to Rye's rules on basic design.
