I found the data below at
http://inflationdata.com/Inflation/Inflation_Calculators/Inflation_Rate_Calculator.asp

It's based upon the Consumer Price Index, provided by the U.S. Government.

Here's what it said:

What cost $62500 in 1987 would cost $116722.44 in 2007.

That's a 187% increase.

So how come that house is now appraised at over $300,000.00, a 528% increase, if inflation has been what the government says it has been?
