I have a hard time feeling sorry for people that took out interest only loans or 125% LTV second mortgages. I don't have any sympathy for the people who lent them the money. That's why you justified charging the high interest rates.
As for the housing market, it is a temporary drop in pricing, either due to regional economic circumstances (MI, OH) or due to irrational exuberence (CA, NV, FLA, any coastline) and overbuilding. The population of this country continues to increase by 3 million or so each year, so demand will catch up with supply some day. I would expect 3-5 years for pricing to return to last years levels. It will take 5-10 years for MI and OH to return. If you don't need to move or are moving to another house in the same community, it won't hurt you one bit. If you are forced to move, you are stuck.
