I always find it strange when people lament the old pension plans. 401k and the like are vastly superior. No worries about restructuring.
We live off of the investment income in those IRA/401k type accounts. Total assets including the farm might reach 2MM, but the investment portion is much less. We 'make' probably 90k a year between us in dividends and such. Only withdraw about 40-60k.
Do a very detailed budget. Use a spreadsheet and be honest with yourself. Include all of your vices. When in doubt, guess high on expenses and low on income.
Once you know the expense number, talk to your investment guy about how to make enough in the market to cover that, plus more.
We will draw SocSec at 62. You never know when you'll go. For most people, they will get more total at 62, YMMV.
That money will be gravy.
Really horrible that we couldn't have opted out. That ~15% of our income invested would have netted millions more than SocSec will return to us. I could have had a 2nd tractor!
