The record-setting housing market has brought anecdotes of frustrated home shoppers being repeatedly outbid and using risky strategies, such as waiving contingencies, to be competitive.  And a new Zillow analysis of the age, sex, race and income of home buyers over a decade reveals Millennials and Baby Boomers — two of the biggest generations in American history — are in the market for homes in a big way, and Boomers are winning. Having deep pockets helps.

With an aging population helped by an improving economy, individuals of every age group over 30 were buyers at higher rates in 2019 than those same age groups in 2009. Still, a major construction slowdown after the Great Recession contributed to a lower rate of American households forming in the years since that time. 

There simply have not been enough homes for everyone who wanted to move out on their own. That illustrates the size of the gap that still needs filling and the reason for increasing competition among members of these two large generations, the report concludes.

“Even before the pandemic, the largest-ever generation entering their 30s and the hangover from more than a decade of underbuilding were on a collision course set to define the U.S. housing market,” said Jeff Tucker, senior economist at Zillow. “The pandemic supercharged demand for housing, bringing the shortage into relief sooner than we expected, as Millennials sought bigger homes with Zoom rooms, and older Americans accelerated retirement plans, spurring moving decisions.”

Although Millennials are the biggest players in the housing market, buyers are trending older. The median age of a recent buyer — somebody who bought a home in the past year — was 44 in 2019, up from 40 in 2009. That’s largely because Baby Boomers, who make up a big share of the population, are also more active in the housing market than those their age 10 years ago. The share of recent buyers who are 60 years and older grew 47% from 2009 to 2019. Over the same period, the share of recent buyers ages 18 to 39 fell 13%. 

This means that Millennials, already grappling with skyrocketing housing costs from pre-pandemic housing trends and student debt that make saving for a down payment a steep hill to climb, also generally have more competition from their parents’ and grandparents’ generations than their predecessors did. That dynamic is likely one reason the share of buyers who were buying their first home has trended down from 46% in 2018 to 37% in 2021. 

More than half of homes sold in July went for above their list price, usually meaning the buyer expected the home to receive multiple offers. Home values grew 31.2% from 2009 to 2019, and they’ve grown an additional 22% since then, representing massive equity gains for long-time homeowners. Because Boomers are more likely to be homeowners who can use the proceeds from the sale of their current home toward their next one, they have a built-in advantage in a bidding war against younger buyers, who are often buying their first home. 

A survey of Zillow Premier Agent partners found all-cash offers, which are more common for repeat buyers, are the top strategy for winning a competitive bid.

“There are many hurdles Millennials must overcome when buying homes of their own, one of them being fierce competition from the next most populous generation: Baby Boomers,” said Tucker. “Whether downsizing or moving to a new town, Baby Boomers being more active means competition that previous generations did not have when buying their first home. And older buyers have the advantage of a lifetime’s worth of savings and home equity to leverage in a competitive offer.”
