Your the one being obtuse with your stupid national chart. When you buy a house you aren't buying the entire US housing market so it goes without saying that if you overpay for a home in a declining neighborhood and/or sell at the worst time in history you might lose money. Your the only one in this thread that needs it to be pointed out that specific home you buy and the price you pay for it and the neighborhood you buy it in and the market you buy/sell in affect whether or not you make money.

Do you look at this chart and think that if you bought ANY individual stock in 1955 that you would have made money selling it 50 years later?
