If you have a fixed-rate mortgage with a monthly payment at a comfortable level, then the mortgage should represent a very low source of risk. Having 12~18 months of payments in the bank saved up for a rainy 1.5 years is a great plan to mitigate that.

The idea of personal comfort is interesting, I think people should attempt to quantify the value of being mentally released of debt burden -- maybe for some there is very high value in it. For me personally, I have always been comfortable with the idea of strategic debt as a way to advance certain goals.

I think what your approach neglects is the fact that being conservative is risky as well. In the last five years, of course, it would be hard to make that case. But unless you die soon, there will definitely be times where you will be left behind -- relative to your economic peers -- if you don't finance your activities externally.
