500k for a house flat.
1m at 5% dividends / yields gets you about 4k/month. Some of that goes to taxes, and some you need to put away for recurring costs like house and car maintenance/ upgrades.
The point is you never sell that original 1m investment, and with how bad inflation is (much higher than 5% and getting worse), you will want some dividend+growth stocks and not all CDs or bonds..
also some of that income you’ll want to try to get some gold/silver.
If the market takes a huge tumble that 4k/month could crater to 2k for a while.
In summary..
1.5m can net you a frugal and safe life with no working for 50years either proper management and no woman/kids.
If you somehow find a woman that is willing to work while you sit there then maybe a kid is possible.
I would add 500k for every additional person.
So 2.5m for 1 woman 1 kid if no one works , since they will demand additional goods and experiences beyond frugality (and u don’t want to treat them like garbage).
