I got very lucky on the timing (purchase and recent sale) of a rental property in Boise, ID. The sale generated a large sum of money that is mostly tax free.

My objective for this money is to invest it such that in 12 years when I retire from the military with a pension at age 47, I am able to live off of the combined income (from the pension plus this invested sum) without working until I turn 60 and am able to access my other retirement accounts penalty free. I don’t know that I absolutely won’t want to work, but I want to have the option to do so from that point forward.

The simplest thing to me is just put it into low cost index funds. My question is asset allocation. Should I go heavy on the stocks and light on the bonds knowing that interest rates will likely rise in the intermediate future and I have a lot of runway left in front of me in my potential working career?

Or should I go heavier on the bonds as though I was actually 12 years from “retirement”, even though my early retirement date at 47 is just a goal and I could work past that point if I needed to?

Or am I missing the boat altogether and are both of these options bad?
