And fewer 25- to 34-year-olds are living with a spouse or partner, Business Insider's Akin Oyedele reported in 2017, citing Census Bureau data. It suggests that milestones — like marriage — that often precipitate buying a home are happening later.
More millennials are living with roommates because they can't afford rent, let alone a house.
But renting is expensive, too. As a result, more millennial renters are living with roommates to cut costs.
In an article for The Atlantic, Allie Volpe reported the facts: From 2005 to 2015, the number of Americans aged 18 to 34 with roommates increased by 23%, according to the US Census Bureau. This doesn't count those living with a romantic partner, but does include those who live with their parents.
While cohabitation is a departure from the 20- and 30-somethings who lived with their significant other in the past, it's nothing new — immigrants and workers sought out boarding houses during the 19th century.
"Companies like Open Door, HubHaus, and WeLive, a subsidiary of co-working giant WeWork, are competing for millennials' dollars as young people continue moving to high-priced urban areas," wrote Melia Robinson for Business Insider.
Many millennials also still live with their parents.
"This should not necessarily be viewed as a negative thing as long as there are clear fiscal goals in place," Doyle Williams, an executive vice president at Country Financial, said in a press release, adding that using this time to build an emergency fund, save for a down payment, and focus on long-term goals can help millennials build financial independence.
In fact, millennials are waiting so long to buy homes that many of them are bypassing the need for a starter home altogether.
By the time many millennials do buy homes, they're older and less likely to move around as they settle down.
Waiting longer to buy also gives millennials more time to build up their resources for a down payment. As a result, for some, their first home is a million-dollar luxury home, not a starter home. They are thus bypassing the need for a starter home altogether.
The trend of unmarried millennial couples buying a home together has become more prevalent, Daniel Gershburg, partner at real-estate law firm Romer Debbas LLP, told Business Insider. According to a Coldwell Banker Marriage and Homebuying Study, a quarter of American millennials purchased their home with their current spouse before getting hitched.
Millennials are being more selective, seeking suburbs with good weather and good jobs, typically in the Sunbelt, William Frey, demographer at the Brookings Institution, told Bauerlein.
As a result, these suburbs are growing at a rate that's more than twice as fast as their neighboring cities, he said. In some areas, like Apex, North Carolina, the trend is creating an overcrowding problem, resulting in traffic jams and schools filled past capacity.
And they're not just stopping at the suburbs: Millennials are moving even further out, to the exurbs, for cheaper homes.
Some millennials are taking their search for affordable housing even further than the suburbs: They're buying homes outside the affluent suburbs and reviving the exurbs for the first time in a decade, reported Laura Kusisto of The Wall Street Journal. On average, these homes are more than 16 miles from central business districts — the greatest distance since 2004, Kusisto reported, citing Fannie Mae loan data.
While the housing market has slowed in America, more home sales and constructions are popping up in the exurbs, Kusisto wrote: "Rising mortgage rates and home prices, especially in urban centers, are once again motivating buyers to drive until they can afford a home, including in Dallas, Las Vegas, Atlanta, and the San Francisco Bay Area. Low gas prices help as well."
Those who have committed to the move have found that the savings are worth the commute time, which can be up to two hours.
