The Summary – The housing market continues its pricing decline, but it looks like it may be the beginning of the end for the downward spiral in pricing. An historical analysis of the Tampa, FL market suggests that median home prices may have reached inflation-adjusted parity with home prices in 1994. This price parity for the median home in Tampa is $161,000 in today’s dollars, 44% below the peak in median pricing of $287,500 in September, 2005. This compares well with the estimate of actual average sales transaction prices in Tampa of $160,530 in January by the ERA Polo Real Estate Group.
Nationally, the supply and demand of new homes also appears to have reached a balance. New home starts in February of 358,000 is within 6% of new home sales 337,000. For homebuilders, this suggests a possible end to the downward spiral in pricing for their new products. However, it does not necessarily suggest an end to the downward pricing pressure of existing homes, as foreclosures, job losses, and general insecurity in the employment market continue to pressure existing home prices.
The building industry may see a pricing bottom here, but the potential supply of homes will probably exceed new home demand for some time to come. Times will continue to be challenging for the home real estate market, but the phase of speculative excesses appears to be at an end. Hopefully the next phase will be one of recovery, but it will depend on the general economy to right itself.
On to the Numbers -
In the spring of 2008, I put together the following graph and calculations based on the Case-Shiller Index (CSI). I was trying to decide what to do with our house in Tampa, as we were moving to Oregon.

(The spreadsheet used to create this graph may be found in this hyperlink.)
We had listed our house in Tampa in January 2008, but by February we were receiving very little interest. We were wondering whether we should lower the price to help generate its sale. In retrospect, I wish I had done this “back-of-the-envelope” calculation in the Fall of 2007, as I might have listed our house at a lower price to begin with and perhaps sold earlier at a higher price.
In any case, it is a pretty straightforward calculation that charts the CSI versus time (blue diamonds). I regressed time versus the index from January 1987 to April 1994, which appeared to be a period of stable pricing. I projected this forward in time (pink line) to create a basic long-term trend. I then regressed time versus the index between September 2007 to March 2008 to create a short-term trend (blue line).
As is pretty evident, the pain in the housing market predicted from this short-term/long-term relationship suggested that things would get much worse. We quickly lowered the price of our home to sell it as soon as possible (and had contract within two weeks).
Remarkably the trend since February 2008 has pretty much followed the blue short-term trend line, with a little jog during the credit crisis of the summer of 2008. The question now is whether the pricing in the housing market will continue to fall.
The top of the Tampa market was September 2005, and the median asking price of a house at this time was $287,500. A fall back to the pink long-term trend line would yield a median price of $107,200. However, the CSI is a nominal pricing index, and none of the values have been inflation adjusted. Since 1994, there has been some real inflation in the cost of building a home beyond the speculative increases in price. In addition, there have been other factors impacting the cost and pricing of new homes since 1994 beyond the most recent speculative excesses. These include increasing median square footage and upgrades in finishing costs (e.g. granite counter tops) that are beyond the norm of the typical 1994 new home. These factors would yield a rise in the price of a new home based on true costs differences that would need to be considered when trying to find a “bottom” in the median home price today that removed speculative excesses.
Rather than trying to account for all of these factors, let us try a quick addition of inflation to the trends to see if we can surmise a possible end to the median home pricing declines. Average inflation in the CPI over this period was 2.7%. Let us assume a 3% inflation rate in the pricing of homes from May 1994 and add it to our Long-Term Trend (Long-Term+Inflation; red line). This new inflation adjusted trend line shows a crossing with our blue short-term line at $161,221 during March 2009. Recent sales in January 2009 averaged $160,530 (ERA Polo Group), suggesting we are close to the inflation-adjusted price parity with the median home sold in 1994.
However, it does not suggest a complete end to the pricing declines. The woes of the general economy will continue to impact the housing market. Pressures in the employment market will translate into continued pressure in the housing market, reducing overall demand, and possibly increase supply through short-sales, foreclosures, and relocations.
