The price of homes has been going up for over a decade everywhere. Supply and demand are the factors determinant of price, along with the cost of financing,
Financing, or the cost of money has been below the actual rate of inflation for most of that time. This undermining of the dollar is being supported by the US government and it's trading partners. They are doing a dance with the devil, as many asset classes have been inflated during the same time.
Look at this chart of the US stock market:
http://tinyurl.com/4xz5zLooks like it's been doing pretty well since the bottom in 2002 doesn't it?
Now look at this chart of the same market priced in Gold:

Your anecdotal evidence about land scarcity may justify the price increases in your mind, just as other people have stories or explanations for the out of range price increases.
Short-term interest rates are already rising. Soon, long term rates will have to rise in harmony with them. What do you think happens to people who are leveraged out to the hilt in order to buy these homes, particularly those with adjustable rate mortages? They will be forced to sell, and the more of them in that situation, the worse it will be for the other home owners.
Your home is priced in Dollars. Look at what the dollar has done over the past three years:
http://tinyurl.com/67zjcSee that decline! That's every dollar you have owned for three years, and everything you have a loan on that you service in dollars. The Dollar has gone down by over 30%. Your home may have retained it's value so far, but the dollar isn't done declining by any means.
This is why I've been touting gold for the past few years. It isn't that gold is worth anymore, just that the dollar is worth less.
The US is not competitive as a manufacturer anymore. Labor costs, environmental regulations and the like along with Currency arbitrage make the US a bad place to build a business that makes anything. The past several years has seen the rise of financial service businesses, which make nothing and profit by providing financing. Even large firms that used to manufacture, like GE, Ford and GM are making uch if not most of their profit through providing financing for their products.
Unless people can be gainfully employed, they're not going to be able to afford to buy these absurdly priced homes. And the wages they're paid have to be sufficient for them to service the loans on these homes. The cost of servicing them has to rise because of interset rates. The bond market must be on drugs to charge so little considering how fast certain asset classes has risen.
The US government is awash in debt, and the debt is getting worse not better. This country is writing checks for money it doesn't have, so each dollar we have is loosing value to reflect the difference. It's getting worse, not better. So protect yourself!
