'Dumb! Really dumb!': Dave Ramsey goes on an epic rant about 3 of the most common money mistakes people make. But how easy is it to avoid these financial errors?

However, some argue that economic and social trends may have made some of these mistakes unavoidable. Here’s a closer look at three of Ramsey’s top “dumb” money mistakes and why they’re so common.

Co-buying property

Ramsey despises the prospect of buying property with anyone besides a spouse. He advises against this even in long-term relationships.

“If you’re shacking up, don’t buy a house with your roommate,” he said. “That’s dumb.”

This advice is rooted in the fact that separating assets between an unmarried couple can be complicated. They do not always share the same property rights as married couples. In some states, however, living together could qualify couples for “common-law marriage” and grant them similar rights.

The housing crisis has pushed more people to consider co-ownership of property. A report by Co-Buy, a platform that helps multiple buyers share a property, says 26.7% of home purchases in 2023 were co-purchases, while 30% of these co-purchases were completed by unmarried couples.

Perhaps surprisingly, 59% of co-purchases were made between friends, according to Co-Buy. These strategic moves might be financially risky, but they’re also a response to a stubborn housing crisis across the nation.

Upgrading cars

Ramsey says a totaled car is not a reason to upgrade.

“You were driving a $6,000 car,” he said. “Your car gets totaled, you get a check for $6,000 and, suddenly, $6,000 cars aren’t good enough for you. That’s dumb!”
