From Catherine Rampell at the WaPo: Americans think owning a home is better for them than it is

Over the past century, housing prices have grown at a compound annual rate of just 0.3 percent once one adjusts for inflation, according to my calculations using Shiller’s historical housing data. Over the same period, the Standard & Poor’s 500-stock index has had comparable annual returns of about 6.5 percent.

Yet Americans still think it’s financially savvy to dump all their savings into a single, large, highly illiquid asset.

First, as I've pointed out several times, Shiller used several estimates for changes in house prices. As an example, for the decade prior to 1987 (when the Case-Shiller index started), Shiller used the FHFA index.  However this index was for a small percentage of loans. If he had used CoreLogic instead, the real return over the period Rampell analyzed would have been closer to 1.5% (much higher than 0.3%).

Second, Rampell assumes the buyer paid cash - a much better model would have assumed 10% down, and would have had the buyer refinance every few years as mortgage rates declined. This also means there would be far less invested in the S&P500 than Rampell assumed.

Third, a young person might be happy with a $400 apartment in 1982, but I doubt they'd want to live in the equivalent apartment for 30+ years (marriage, raise kids, etc.).  The model should assume a move-up buyer and renter at certain points.

I'm confident a more complicated  and thorough model would produce the opposite result over the period in question.
