MMM works very hard.
Ignore all the FIRE talk, too much going around.
Look at the numbers, mull things over, decide for yourself.
FIRE is a big turning point, you will have to live with the decision.
Around here, single family rental homes can be had for maybe 100,000, rent for 1000 a month. Do the math for your area.
2M buys 20 homes, monthly income 20K. Add in a reasonable error factor, isn't that possible? Again, do the math for your area.
But this is not true retirement, but it is being your own boss. Taxes, insurance, and transaction fees affect this.
Too much 4% and SP500 talk.
SP500 is a managed fund, perhaps there are others? Perhaps a total stock market, not so managed fund?
4% is simplistic, again, do the research on your own, learn what others do.
We plan on about 5% (and increasing) of portfolio balance each year.
Sorry I can't parse most of what you said. MMM works very hard? That is his choice, he's not working for money, how is that relevant here? Why should I ignore FIRE talk? Just to start..
