Charlie Munger lived in the same house for 70 years: Rich people who build ‘really fancy houses’ become ‘less happy’

For Charlie Munger, living in a relatively modest house wasn’t an accident – it was a conscious decision.

Munger, the billionaire investor and longtime business partner of Warren Buffett, died on Tuesday at the age of 99. He previously filmed an in-depth interview with CNBC’s Becky Quick that aired Thursday night, discussing his motivations for living in the same California home for the past 70 years.

“[Buffett and I] “Are they both smart enough to watch our friends who got rich build these really fancy houses,” Munger said. “And I would say in virtually every case they make the person less happy, not happier.”

A “simple house” is useful, Munger said, noting that a larger house can help accommodate more people — but that’s about it. “It’s a very expensive thing and it doesn’t do you much good.”

Another downside to owning a mega-mansion, he added, is that such a display of wealth could spoil his children by encouraging them to “live grandly.” Munger had nine children in two marriages, including two stepsons and a son who died of leukemia at the age of nine.

“[Buffett and I] “They were both thinking about bigger and better houses,” Munger said. “I had a large number of children, so it was even justified.” And I still decided not to live a life where I look like the Duke of Westchester or something. And I wanted to avoid it. I did it on purpose… I didn’t think it would be good for the kids.”

As Munger alluded, Buffett lives a similar life: The 93-year-old billionaire bought his home in Omaha, Nebraska, in 1958 for $31,500 and has lived there ever since. Buffett’s quality of life would be worse if [he] had six or eight houses,” he reportedly said at Berkshire Hathaway’s 2014 shareholder meeting.

Munger often preached about the virtues of living a modest life, offering advice such as “Don’t have much envy” and “Don’t overspend your income.” In Thursday’s interview, he credited his success and longevity to a long-held sense of caution and the ability to “avoid all common types of failure.”

“Avoid craziness at all costs,” Munger said. “Crazy is a lot more common than you think. It’s easy to go crazy. Just avoid it, avoid it, avoid it.”
