It is estimated that information will have its lowest total of new homes sold since 1992.However, even though the market is in a pinch, one niche of builders is staying busy -those who offered green building options. A survey conducted by the National Association of Home Builders found that buyers would pay more for a house, upwards of almost $ 9,000, if they could save on their monthly utilities (McGinn 49).

According to Daniel McGinn, the housing market is in a major downturn right now in large part due to the foreclosure crisis. It is estimated that this year will have its lowest total of new homes sold since 1992. However, even though the market is in a pinch, one niche of builders is staying busy-those who offer green building options. A survey conducted by the National Association of Home Builders found that buyers would pay more for a house, upwards of almost $9,000, if they could save on their monthly utilities (49).
