Big question that wasn’t addressed:
If you’re single, what will you do for health insurance if you take social security at 62?
Chances are your income will be low enough to qualify for obamacare, and probably free or at least at low cost.
Do I care that it supposedly costs the government $1000 a month to pay for my obamacare and I pay zero for a silver plan? Nope, not any more. All my life I've worked and paid for deadbeats - about time I started getting some of that back. It is not a sustainable system (obamacare) but I'm using it to close the gap between now and when I turn 65.
You pay for it just like everybody else. If that is going to be too much of an expense then wait until 65. I waited until 65 and draw full SS and I still work full time. Wife will retire early at 62 and change her job to part time. She still keeps her insurance. Many work part time just for the insurance.
My wife gets a pension and insurance thru her employer and still works part time for them. Together we are doing pretty well, but if we tried retiring as singles, not so much.
