Is paying off your mortage a #1 personal finance priority?
If you can make enough ROI from the capital you retain by not paying off your mortgage, then why not? I do, I could pay off a significant chunk of mortgage if I wanted but whilst interest rates are low there's little incentive. As for another crash... Well, there's no reason to expect a crash would result in high interest rates, more the opposite, but you should consider what you would or could do if interest rates did jump to 15% for whatever reason. As long as your investments aren't too risky or difficult to liquidate, etc, you could always consider paying off a big chunk then, when it makes sense.
