Seven years ago, Phil Levin and his girlfriend, Kristen Berman, pondered a common question: Should we move in together?
Levin assumed they’d take a predictable path and find a more affordable apartment outside of pricey San Francisco. But Berman, a behavioral scientist, shared her reservations about leaving their friend network – and some facts to back it up.
“All the behavioral science research shows that that’s one of the worst things you can do for your happiness,” Levin says.
Instead, the couple rented a Victorian-era mansion in San Francisco’s Hayes Valley neighborhood and invited nine friends to move in. Today, they co-own a multiunit property in Oakland, California, called Radish, which houses 17 adults and two infants.
It took some effort to find the right property and figure out finances. But the now-married couple couldn’t imagine designing their life — or raising their daughter — any other way.
“Being able to have this extended family of ‘aunties’ and ‘uncles’ close by has been wonderful,” Levin says.
Many co-buyers operate on a smaller scale. But no matter the size of your group, co-buying requires extra planning and paperwork. If you’re willing to get vulnerable about your finances and long-term goals, the payoff of companionship can be worth it.

An advertising sign for building land stands in front of a new home construction site in Northbrook, Ill., Wednesday, Sept. 21, 2022. From rising home prices to soaring interest rates, it’s a daunting time to be a home buyer. To achieve homeownership, some single buyers are trying a different approach: co-buying with friends or family members. But co-buying isn’t a short-term hack – it’s a lifestyle shift. Before you team up, experts recommend having vulnerable conversations about your finances and long-term goals. If you have patience to navigate the obstacles, co-buying can be a uniquely satisfying way to own a home. Plus, for those who are single, the investment comes with an inflation-proof dividend: companionship. (AP Photo/Nam Y. Huh)
KEEP AN OPEN MIND
In the National Association of Realtors’ 2022 Profile of Home Buyers and Sellers, a record-high 5% of first-time home buyers were “other household compositions” – that is, something different than single, married or coupled.
“It can be a great situation, and a way to enter the market that they wouldn’t be able to enter otherwise,” says Don Koonce, a real estate agent in Seattle who has helped dozens of co-buyers during his eight years in real estate.
Many co-buyers Koonce has worked with are platonic friends who have been living together for years. But they’re as diverse as the types of homes they buy, which range from traditional single-family homes to condos and duplexes.
The right home depends on your group’s size and tolerance of personal versus shared space. Houses with basements work well for separate living spaces, Koonce says, or you could remodel.
Recently, Koonce helped a mother and daughter buy a split-level that they renovated into two distinct units, including separate kitchens.
“It was beautiful,” he says. “I don’t see any problem with a resale on that, because somebody could rent it out.”
STRESS-TEST YOUR RELATIONSHIP
Even for family members or experienced roommates, the financial commitment of co-buying raises the stakes.
Ashley Agnew is a n investment advisor and financial therapist with Centerpoint Advisors, a wealth management firm in Needham, Massachusetts. When working with co-buyers, she role-plays worst-case scenarios to “stress test” the relationship, such as how they’d handle major home repairs or theft.
“You really do have to get a little bit financially naked with the person that you’re buying with,” she says. “There has to be a lot of transparency.”
Agnew always recommends that co-buyers seek legal counsel. An estate attorney can draft a cohabitation agreement — something that’s not just for romantic partners, she notes. That way, all parties know what to expect if someone wants out of the homeownership commitment.
“It’s almost like running a minibusiness, especially if it’s not a coupleship,” Agnew says.
An estate attorney can also help co-buyers understand options for titling the home, such as joint tenancy or tenancy in common. Each arrangement has pros, cons and legal obligations.
FIND THE RIGHT RESOURCES
To move your plans from dream to reality, it’s essential to find a lender that is familiar with — and supportive of — co-buyers’ unique needs. That’s often the first hurdle, Koonce noted. Some realtors hesitate to work with co-buyers, too.
“It’s a lot more paperwork,” he says, “and a lot more coordinating and getting people to agree.”
To provide better service, Koonce earned a professional certification established by Seattle-based real estate startup CoBuy. The company offers education for real estate agents, attorneys and lenders, as well as services for co-buyers themselves.
After establishing Radish, Levin found his inbox flooded with questions about co-buying and co-living. The interest exposed an information gap: People craved trusted guidance on how to do this successfully.
So in 2020, Levin teamed up with close friend Gillian Morris to co-found the Substack newsletter Supernuclear. It provides advice, templates and tools to navigate common challenges of co-buying and co-living.
“We didn’t invent this concept,” Levin says. “We’re sort of standing on the shoulders of other people, so there’s sort of a pay-it-forward element where we wanted to have other people experience the happiness and meaning that we’ve gotten through this.”

METHODOLOGY:
In July 2022, the National Association of Realtors mailed a 129-question survey using a random sample weighted to be representative of sales on a geographic basis to 153,045 recent home buyers. The recent home buyers had to have purchased a primary residence home between July 2021 and June 2022. Respondents had the option to fill out the survey via hard copy or online. The online survey was available in English and Spanish. A total of 4,854 responses were received from primary residence buyers. After accounting for undeliverable questionnaires, the survey had an adjusted response rate of 3.2%. The sample at the 95% confidence level has a confidence interval of +/-1.41%.

Co-buying a house: How platonic partners make it work

The real estate market since the start of the COVID-19 pandemic has been tough on all buyers, but aspiring first-time buyers may have struggled most of all.
For much of 2020 and 2021, the housing market faced a challenging combination of high demand and low supply. Young people were already growing into the largest segment of buyers as the Millennial generation came of age. When the COVID-19 pandemic hit, preferences for more living space, increased remote work opportunities, and other factors related to the pandemic encouraged even more people to enter the market. But existing owners proved reluctant to part with their homes, with supply on the market reaching a record low late in 2020. As a result, competition in the market drove the median home price up by 36% over the last two years. The run-up in home values was good news for people who already had equity in their homes, but it pushed prices out of reach for first-time buyers.
More recently, persistent inflation—and policymakers’ responses to it—have also made it harder to save up for a home. The prices of household essentials like groceries, energy, and especially rent have grown quickly over the last 18 months, leaving first-time buyers with less money to set aside. And now, as the U.S. Federal Reserve raises interest rates in efforts to combat inflation, the costs to take out a mortgage loan have risen dramatically. The average 30-year mortgage interest rate in the U.S. is more than double what it was at the start of 2022, translating into hundreds more dollars per month in payments for would-be buyers.

Co-buying a house: How platonic partners make it work
While recent trends in the market have been especially challenging, buyers have struggled with affordability for longer than that. One issue is that the rate of growth in home values has outpaced that of household incomes over the last 20 years after adjusting for inflation. From 2020 to 2021, median home values increased by 37.8%, while the median household income grew by just 8.78% over the same span.

Supply has been another constraint for first-time homebuyers. The U.S. faces a shortage of housing overall, but builders are also building fewer of the smaller, more affordable homes they used to. Single-family one- or two-bedroom homes represented 24.1% of newly built homes in the mid-1980s, but just 6.2% today. Over the same span, the share of 4+ bedroom homes among new builds grew from 19.3% to 49.6%.

Co-buying a house: How platonic partners make it work
While conditions are challenging overall for new buyers, some parts of the U.S. are more favorable. Ideal markets for new buyers display a combination of adequate supply, a high share of smaller homes in the housing supply, relatively low sales prices for starter homes, and strong homeownership rates among young people. By these measures, West Virginia is the best state in the country to find a starter home, followed by Oklahoma and Mississippi. At the local level, Southern and Rust Belt cities lead the way.
The data used in this analysis is from the U.S. Census Bureau, Zillow, and Redfin. To determine the locations where you’re most likely to find a starter home, researchers at Construction Coverage calculated a composite score based on the percentage of homes with three or fewer bedrooms, the median sale price of homes with three or fewer bedrooms, the months of supply of houses for sale, and the homeownership rate for householders under 35 years old. In the event of a tie, the location with the greater percentage of homes with three or fewer bedrooms was ranked higher.
Here are the U.S. metropolitan areas where you’re most likely to find a starter home.
