'Green' mortgage ups purchase power

Cost of energy-efficiency improvements rolled into loan

A friend of mine, Phil Hall, is the managing editor of Secondary Marketing Executive magazine, one of the more esoteric trade publications dealing with the secondary market for mortgages.

On a more prosaic level, however, Hall has become a very passionate supporter of something called the Energy Efficient Mortgage, or EEM. Sometimes called the "green mortgage," it is a type of mortgage that credits a home’s energy efficiency in the mortgage itself.
