If we follow the long term trend, values and inflation will eventually meet up. If you plot the nominal values (non inflation adjusted) and inflation on the same graph, and normalize the two to match at some point in the past, you would see that they track roughly together from about 1950 until the late 1990s. The values line would jerk around a lot, and be above the inflation line sometimes and below other times.
Starting about 1999-2000, the home value line would have diverged significantly from the inflation line. Since about 2005-2006, the value line turned down. But, in many places, the value line would still be well above the inflation line.
Here's an example of what I think we would see with this graph:

I lived through that boom in the late 70's. Notice how prices fell and at the same time the inflation rose, and by about 1987 the two lines catch up with each other. Notice that it took until about 1998 for prices to get back to the same NOMINAL level as 1982.
I suspect we will see the same sort of trends in residential real estate. I say that because lending guidelines are more like they were before the boom. However, I don't think securization is here to stay. So, its possible the new trend line will track inflation, but at a higher level.
