I'm retiring now, at 47. My wife retired in 2008 (we're the same age). We have a house, fully paid for, worth at least $1M (bought it in 2010 for $900,000 and invested at least $100,000K in renovations), we have $900,000 in my mom's accounts (she's not well and 87 and I'm the only heir, she has full time care in her own house, she lives abroad, her costs are essentially paid for by SS and my dad's pension, still going at almost 40 years), about $400,000 in ours, and we are selling a family property that I have managed for 17 years for $4.5 million this year. I was going to take the property and do a 1031 exchange, but I'm not sure anymore. Maybe I should just stick it in index funds plus a little gambling (on specific stocks and sectors in the market). I've gotten lucky, although also done things well too. My father wanted me to sell that building when it was worth $1.5 million. That was only a decade ago. There's a lesson with my building btw, which is that private real estate funds pay crazy money that makes no sense according to traditional real estate metrics.
We aren't full MMM types by any means, but I'm pretty sure that with a $200,000 draw, we will be fine into our 90s.
There's one thing that I don't see in any of these posts and that's kids. I want to leave something to my kids, ideally about the same amount of cash, divided by two. They don't need to get most of it until their 40s, when we are in our 80s, but I think of this as dynasty building. We don't want to die broke. So if you're going to leave cash for your kids, you need to have quite a bit more.
