DH is 55 and I'm 51. About six years ago we decided to ramp up the payments on our mortgage and get it out of the way for retirement. We were able to pay it off in March, 2006. During this time, we maxed out the retirement accounts. When the mortgage was gone, DH continued to max out his 401k; then, we put the rest in taxable accounts. He retired six months ago.
We did not want to 72T, therefore we accumulated seven years of living expenses in after tax.
There's no need to complicate, our time is short..
