Congratulations on getting rid of your CC debt, and on track to pay off your home in 5 years!
It sounds like you are doing all the right things.
I think you are asking what do you do with the gap in time between when you retire (say 56) and draw social security (say 62).
If your projected and actual stash is at least 25*32000 ($800,000) by then - no problem, just draw 4 percent a year on it and you'll have your $32,000 needed. If it's less by one or two hundred thousand, I'd just draw a little more, until your start social security, then back it down so that the sum of your draw + SSI equals $32,000. In the latter scenario, let's say you had $640,000, draw 5 percent and you have $32,000 a year. The stash will probably get smaller in the 6 years you are waiting, because you are overdrawing on it, but what the heck, that's a small price to pay to quit the rat race 6 years early.
