I, too, am uncertain about one particular aspect of this...the Roth Conversion Ladder.
I understand the advantage of it for people retiring early, what about for people not retiring early? The earliest DH would stop working is age 60, and he can access his funds without penalty at the point. He only has two chances to access his retirement funds after retiring, too, which potentially complicates things.
Would there still be a point in doing the Roth Conversion Ladder to save taxes down the road? Or is it not that big a deal if you retire after 59.5?
