Yet Another View on Why a Home Is One's Castle

We compute equity-based real after-tax rates of return for homeowners and landlords in the United States for 1952–2005. The study confirms that a combined aggregate for residential housing provides a high average net return and low volatility, has low correlation with financial assets and can provide hedge against inflation. The efficient frontier analysis shows that the optimal portfolio for a household with a coefficient of relative risk aversion of four to five is one which contains a bit larger amount of housing than stocks, close to what one observes in the real world.
