Certainly, lets have an constructive agrument. Here are a few points to start with:Quote from rew:
Glad you asked.
(A) You should compare the total return of gold vs real estate. Even assuming that your real estate has appreciated at the rate that is slower then gold, it has been earning carry in one or another form. Either you were able to borrow money against it and offset it with rent or, if you had cash upfront, you'd collect rent or save money while living there. Gold, on the other hand, would have accrued negatively, since you would have to store it some place safe. It's safe to assume that on average real estate carried about the mortgage rate while gold accrued negative 25bp (or more, depending on your storage arrangements).
(B) Anecdotal evidence shows that residential real estate has appreciated a lot more then commercial real estate (in fact, that is the reason for a multitude of commerical to residential conversions in the recent times). Another anectodal data point (aside from the ones that I have already provided), in Mad Men there is a moment when someone is buying a 2-bedroom plus a dining room Park Avenue appartment for 35 thousand. You could probably guess what that would be worth now.
(C) I am pretty sure our RE/CMBS guys will have some data on Manhattan going back that far and I will ask them. The MIT paper looks a little bit fishy.
