Amidst concerns baby boomers will have difficulty selling their homes, here is a suggestion that buying a McMansion can derail retirement plans:

We occasionally hear about a friend who somehow saved up enough money, or just decided to chuck it, and walks off to retire at age 60, 55 or even 50. It can be done.

Also, some people live in a McMansion, drive a Tesla, and vacation in the south of France. But we know it’s a very expensive lifestyle. And we know we all can’t afford it, as the real estate bust of the 2000s so cruelly reminded us. We need to appreciate that, like buying a McMansion, taking early retirement is a very expensive proposition. Yes, a fortunate few can afford it. But most of us just have to get real.

Two things are interesting here. The first is that purchasing a McMansion seriously hampers retirement plans. Purchasing one uses up a lot of money and saddles the owner with a large mortgage (plus the home might be underwater and it can cost a lot to fill such a large home). A more prudent investor would purchase a more modest home rather than splurging on a McMansion.

The second interesting part of this is the comparison to owning a Tesla or vacationing in France, both relatively rare things. For example, Teslas start around $70,000 and only about 22,500 were sold in 2013. In the 2000s, it was common to see McMansion purchases compared to SUVs, a mass production item that cost much less than a Tesla. The implication then is that McMansions are even rarer today, making it even more of a folly to own one.
