From 1980 - 2000, home values appreciated at a rate of 26.5% every 5 years. Each 5 year increment was close to that number, ranging only from 25-29%. Then something strange happened after 2000 - home values appreciated 89% in the following 6 year period! This 89% increase in home values was simply unsustainable. The market's recent decline is a move towards stability and a healthier market.
