At the other end of the spectrum are Dallas (down only 6.26%), Charlotte (off 8.13%) and Denver (down 10.25%). (Note: the percentage declines I am quoting are from when the national peak was hit, the numbers in the graph are relative to that city's individual peak, so there is a little bit of difference.)
No Support for Home Prices
The homebuyer tax credit was propping up home prices, but now with that support gone, prices are resuming their downtrend. People had until June 30 to close on their houses, and they had to agree to the transaction by April 30. That pulled sales into those months that might otherwise have happened in July or August. The credit was up to $8,000, so almost nobody would want to close their deal in early July and simply leave that money on the table.
The tax credit is a textbook example of a third party subsidizing a transaction. When that happens, both the buyer and the seller will get some of the benefit. The buyer gets his when he files his tax return next year, the seller gets hers in the form of a higher price for the house.
Since the tax credit is now over, that artificial prop to housing prices has been taken away. Sales of existing houses simply collapsed in July, after the credit expired, and have remained depressed ever since. The extremely high ratio of homes for sale to the current selling pace is sure to put significant downward pressure on prices.
There is still quite a bit of "shadow inventory" out there, as well. That is, homes where the owner is extremely delinquent in his mortgage payments and unlikely ever to make up the difference, but that the bank has not yet foreclosed on or foreclosed houses that have not yet been listed for sale.
