The real estate to gold ratio measures the amount of gold it takes to buy a single family house. Based on the pioneering research of Robert J. Shiller and Karl E. Case, the Case-Shiller Home Price Index is generally considered the leading measure of US residential real estate prices. The index has a base of Jan 2000=100 and is multiplied by 1800 in order approximate the Average Sales Price of Houses Sold for the United States.
The ratio has an interesting historical track record for identifying turning points in long-term gold price trends. When exatly is one of the assets "cheap" and what is "expensive"? Answering that question is where the Gold/Housing ratio is quite useful. As there is no dollar component in the ratio itself, inflation concerns drop out, and we are left with the value of two of the most popular tangible investments relative to each other.
