Financial assets are about 70% stock, 30% bonds/cash. Stock is about 70% US, 30% international (24% developed 6% or so emerging).
Since I spend almost entirely in US, am comfortable having some local bias. Overall portfolio includes home with low leverage (equity is close to half of portfolio, LTV under 40%), renting out rooms in my home (over half my income!) and a defined-benefit pension account. The international stocks are partly a cushion against US collapse, overlapping with an assumption of steadier returns through diversification. I am 50something and not from long-lived family, so am less volatility-friendly than some Mustachians; therefore the "steadier returns" have value for me. Like the US stocks, the international stocks keep me in the game.
