re: 401k options if ready to retire early?

There are probably more but generally there are 3 common ways to pull your money out of a 401k for early retirement.

1. Rule of 55
2. 72T (SEPP)
3. Roth conversion ladder

Roth conversion ladders provide the most flexibility but you have to be able to fund the gap (5 years) before the funds are accessible. Essentially you start doing roth conversions once you have retired. The conversion is taxable hence why you generally don't start until your normal income is low (to limit taxes). The amount you have converted to Roth can be withdrawn tax and penalty free after 5 years. Any gains on that conversion is not available tax and penalty free after 5 years if you are still younger than 59.5.

As mentioned you will need funds for the first 5 years and then your roth conversion ladder can be used to fund your life. Some common methods of bridging the 5 years are savings/checking, taxable brokerage account, previous roth conversions (greater than 5 years ago), roth contributions, etc. It is very flexible because you can convert any amount you want based on taxes, cost of living, etc. You can also convert a different amount at different times as well.
