The housing bust, adjusted for inflation
The new Case-Shiller house price numbers (through January) came out yesterday. It was widely reported that they were ugly, and they were--the 20-city composite index was down 10.7% since January 2007 and 12.5% since its peak in July 2006.
I was curious how much worse things would look if adjusted for inflation. Here's what I found out, with help from Time graphics czar Jackson Dykman and his Time.com counterpart Feilding Cage in ugly Excel form because something was wrong with the pretty version:

What was interesting to me was that adjusting for inflation (I simply used headline CPI) didn't make the decline look dramatically worse; it just made it look different.
[Update: No, I don't know why the chart doesn't show up in Firefox. It's there in Safari. I'll see what I can do to fix.]
In the inflation-adjusted version, housing prices peaked in December 2005 and they've declined 16.6% since then, bringing us back to the level of early 2004. So we appear to be substantially farther into the housing slump in real terms than in nominal terms. Which might actually be a good thing.
"If they could generate enough inflation," economist Ken Rogoff told me last week, "I guess the Fed could make the house price problem go away." What he meant was that, if we had double-digit inflation, house prices might stop going down in nominal terms. He did not mean this as a serious policy suggestion.
But the Fed is tolerating 3% to 4% inflation, and that's making the impact of the housing decline less dramatic than it would otherwise be. It's the real (inflation-adjusted) price that counts when you're talking about housing affordability. It's the nominal (unadjusted) price that matters to borrowers and lenders. We need a real housing price decline to get prices back in line with incomes and rents. But if we can inflate our way out of a little bit of the nominal house price decline, we reduce the risk of economy-paralyzing insolvency problems in the financial sector. (Just ask Irving Fisher.)
Now inflating just a little bit can be hard to do. The Fed is clearly playing with fire here. But hey, without fire, our civilization wouldn't amount to much.

When I pull the image url out of the source:
and try load it in FF directly, it says:
"The image “http://time-blog.com/curious_capitalist/inflationhousing.jpg” cannot be displayed, because it contains errors."
IE also balks. I'd say the image file itself is unhappy on PCs.

I ended up right-clicking on the link above, save link as onto my harddrive and then opened it with a different program. IE and Firefox for some reason can't open it, but Windows Picture and Fax viewer can.

The problem with the graph, is that "100" is set to whatever year you want. I feel that in the year 2000 a housing bubble was already inflating prices so using that as the "normal" price may not be accurate. Set 100 to the 1997 prices and it looks worse for the future. I can also set to 2004 and it looks like it will turn around soon. I'd rather it just track the cost of homes over time in inflation adjusted numbers for as long as possible so we can see how far off of historical norms we are.

The 20-city Case-Shiller index only goes back to 2000. But yeah, it'd be fun to mess around with their 10-city index, which has a much longer history, and the inflation data. I'll work on that.
