Millennial Housing Divide: Older Enjoy Boomer-Like Comfort, Younger Revert to Early 1900s Patterns

Millennials, once painted as a monolithic generation struggling uniformly with housing, are now starkly divided. Jessica Lautz, deputy chief economist at the National Association of Realtors, has been tracking this shift for years. Her research, released in April, highlights a structural split: older millennials, aged 36 to 45, are living a boomer-style existence. They boast a median household income of $132,700, buy the largest homes among generations at a median 2,100 square feet, and only 33% are first-time buyers—meaning most already own homes and are leveraging equity to trade up, mirroring boomer behavior.

But younger millennials, aged 27 to 35, face a vastly different reality. Research from the Federal Reserve Bank of Minneapolis, led by Erik Hembre, reveals the real under-35 homeownership rate is closer to 22% than the widely cited 37%. Their median down payment is a meager 9%, compared to 13% for older millennials, 19% for Gen X, and 26% or more for boomers. Student loans delay purchases for 44% of younger millennials, high rent holds back 42%, and credit card debt affects 30%. It’s a three-pronged squeeze they largely escaped by buying earlier.

The National Association of Realtors now splits millennial data into two cohorts because the gap between them is too wide. Younger millennials are buying 1,600-square-foot homes, a 500-square-foot difference from their older peers. Realtor.com’s data shows a record 25.2 million adults under 35 lived with parents in 2025, nearly one in three, surpassing pandemic peaks. This isn’t about idleness; it’s about housing costs. The national median home listing price is $430,000, 34.4% above 2019 levels, and rents are nearly 18% higher than pre-pandemic norms.

Pew Research in 2014 noted a historic milestone: for the first time in over 130 years, 18-34-year-olds were more likely to live with parents than in their own household with a spouse. The question lingers: are younger millennials delaying marriage and homebuying due to changing behaviors, or are housing costs making it impossible until later in their careers?

Boomers aren’t downsizing significantly. Those aged 61 to 70 sell and buy homes of median 2,000 square feet, with minimal net change. Only those 80 and older downsize meaningfully, giving back 300 square feet. Lautz notes boomers want to hold onto their space, perhaps for holidays or personal belongings. Some boomers are recognizing their children’s affordability struggles and purchasing multigenerational homes. Gen X, the “sandwich generation” caught between aging parents and children, remains the largest buyer of multigenerational homes, with older millennials beginning to follow suit as they hit their 40s.
