A recent analysis on Realtor.com uses the term McMansion as shorthand for a large house owned by a Baby Boomer. Here is the crux of the argument regarding the habits of millennials:

“They’ll buy a smaller house with fancier amenities, close to town, rather than chase square footage,” Dorsey says.

This argument has been made for several years now: millennials are willing to live in smaller homes but desire certain amenities. But, is every big house a McMansion? No, no, no – a minority of American homes are over 3,000 square feet but not all of them are McMansions. Even if they meet the size requirement, they may not be teardowns, suffer architecturally, or exist in lonely suburban communities or all house crass consumers or the nouveau riche. And do all Baby Boomers live in McMansions? Of course not. There may be broad patterns at play here – Baby Boomers have plenty of houses to sell, millennials may not want all of those particular homes – but using loaded terms like McMansions or suggesting incompatibility across entire generations may be going too far.

Side note: this Baby Boomers vs. millennials in the housing market is gaining steam across media sources. How will the Boomers sell all of their houses? (See earlier posts here and here.) What do millennials want in houses and communities? (See earlier posts here and here.)
