Appraisers did not cause the housing bubble

I've read several blogs that have tried to blame the housing bubble on appraisers. Appraisers did not cause the real estate bubble. It was lacks loan requirements originally pushed by politicians who complained that lenders weren't lending enough to low income individuals with bad credit. Solution - no income verification liar loans. More people were able to buy homes they couldn't afford due to low 2 to 5 year adjustable starter rates. This pushed housing demand up and prices with it. Add to that illegal aliens who were also able to get these type of loans. Some were buying 2 and 3 homes with no income verification. Buyers were willing to pay whatever the asking price was because they figured they would just flip the house and make a profit. Wages and home price ratios went out of whack. Now the adjustable rates are coming due and many who lied about there incomes and ability to pay are being brought to light. The liar buyers are being forced out of there homes and those homes are flooding the market. Since no income verification loans are no longer available (unless you have a very low LTV ratio) home value to income ratios are coming down to historic norm which is forcing home prices back to historic norms. Appraisers did not caused the bubble. If they did why aren't they able to keep the bubble up? Why didn't appraisers create a bubble prior to the availability of liar loans? Fraudulent appraisers? - There are fraudulent people in all different business not just appraisers. Fraudulent loan officers, realtors, lawyers, doctors, politicians, etc. A totality of buyers and sellers in any given market determine market values. Not the appraiser. The appraiser only reports what price buyers and sellers are willing to buy/sell a home for in a certain time period in a given market. Property values doubled in a 5 year period in Florida. Now the politicians are trying to figure out how to keep home prices from dropping (so they can keep that huge unwarranted windfall in there own homes and keep high taxes pouring into the government) by pumping trillions of taxpayer dollars into the economy. Only thing is if they are able to keep home values artificially high young people just coming out of school will now be paying 600k for a home that was selling for 300k just 5 years ago (more like 8 years ago now). Having these first time home buyers pay an extra $300k for the next 30 years through manipulated markets just isn't right. Let the market decide. Not the politicians. And stop blame the appraiser. Why didn't appraisers create a housing bubble in the 1990's ? People are lossing there life savings because housing prices are declining? I don't think anyones life savings plan was to buy a home, work for a number of years and then gain $300,000 in five years on the home they lived in. Those that were planning for that sold there home at the top of the market and downsized into a smaller home.
