So that is 84k per year.
You are 45
You could wait till you IRA hits 1.5M and then you could use the method SEPP Substantially Equal Periodic Payment
This method gives you the ability to withdraw your IRA with no penalty. You could withdraw around 100k a year with 1.5M if you are 45.
Also you could buy 150K of MSTY and that currently yields 120k a year. An insane product. It's been running for 2 years.
So you could stack msty until you reach that 150k.
I would never sell my self custody too valuable. I don't like the lending products because right now 13% interest if too high.
It also depends if you like your job or totally hate it. How fast do you want to retire?
Hope this helps
