Rising home prices and high monthly payments have prompted many younger buyers to consider alternatives to traditional solo homeownership. While buying a house on your own or with a spouse was once seen as the two “normal” options, for some, teaming up with a trusted friend, sibling, or partner has become a realistic way to buy sooner and split costs. A co-ownership home turns home buying into a shared effort — and interest in this type of ownership is growing rapidly.
A co-ownership home is a property purchased and owned by two or more people, typically with a joint mortgage. These co-buyers may be friends, siblings, coworkers, unmarried partners, or extended family members. Instead of one person taking on the entire down payment, mortgage, and upkeep, co-owners pool resources and divide responsibilities.
Most co-buyers choose either joint tenancy, which involves everyone owning equal shares with survivorship rights, or tenants in common, where ownership percentages might differ, and each owner can transfer their share independently.
A real estate agent or mortgage lender can help you understand the best ownership structure based on what you and your co-buyers want. And if it sounds like a lot to wrap your head around, don’t stress. A quick conversation with an expert now can bring all buyers on the same page and help keep the buying arrangement structured and fair.
Affordability challenges continue to reshape how aspiring homeowners enter the market. The typical homebuyer is now 41 years old, according to a HomeAbroad study, up from 29 in 1981. Only about 5% of buyers are under the age of 25. Many younger adults are delaying major life milestones due to high home prices, limited inventory, student loans, and higher borrowing costs.
There is also a cultural shift toward nontraditional buying arrangements. The 2025 Coldwell Banker American Dream Report found that 36% of hopeful buyers have considered purchasing with family members, while 33% have considered buying with friends or coworkers. Co-buying enables individuals to enter the market sooner, build home equity earlier, and access neighborhoods or properties that might otherwise remain out of reach.
Buying with another person can strengthen a mortgage application and improve purchasing power.
“With more than two in five Americans struggling to keep up with their monthly housing payments, many buyers are getting creative and teaming up with friends or family for joint mortgages,” Bill Banfield, chief business officer at Rocket Mortgage, said via email. “Our latest Rocket Mortgage data shows that 11% of homebuyers plan to buy with a friend in 2026, and just over one in 30 buyers expect to buy with a sibling.”
Banfield said that combining two or more incomes can help co-buyers qualify for a more competitive loan or afford a wider range of homes, especially in a national housing market where the median home price costs well over $400,000.
He added that combining incomes can strengthen a mortgage application, but everyone’s debts count toward the group’s total debt-to-income ratio (DTI), which is calculated by dividing your total monthly debt payments by your gross (pre-tax) monthly income.
After closing day, co-owners also share the monthly mortgage payment, utilities, insurance, and routine maintenance. “Instead of one person carrying all the costs, co-buyers can divide them, making homeownership more manageable and attainable in today’s high-cost environment,” Banfield said.
Co-buying can be a smart way to make homeownership happen sooner, but it also comes with shared responsibilities. Understanding these risks ahead of time helps buyers avoid stress and plan for a smoother long-term experience.
Buying with someone else means each co-borrower is legally responsible for the full mortgage payment, not just their portion. If one person misses a payment, it affects the credit of every borrower. Lenders can also pursue repayment from any borrower whose name is on the loan.
For these reasons, co-buyers should discuss income, debt, emergency savings, and contingency plans early to ensure stability.
Lifestyle and long-term alignment issues
Sharing a home requires alignment on expectations around guests, cleanliness, pets, use of shared spaces, and renovations. Long-term goals also matter. A job change, a new relationship, or a desire to relocate can quickly shift the dynamic. Honest conversations up front help prevent misunderstandings later.
Life changes, right? That could translate to one homeowner needing to move. If you co-buy with an older family member, that co-owner of your home could pass away. Without an exit plan, removing a buyer from the mortgage could cause stress — especially if finances or timelines differ.
All owners should agree on how to value the home when a buyer wants out, how a buyout would work, and what would happen if refinancing isn’t affordable. A written agreement sets clear expectations before emotions or pressure escalate.
When one owner decides to move on, the remaining owners need to determine how ownership will be transferred. The best option depends on the home’s equity, mortgage terms, and the original ownership structure.
“One common option when a co-buyer wants to sell their portion of the home is a buyout,” Banfield said. This often involves a cash-out refinance in which the remaining owner takes out a new mortgage and uses part of the funds to pay the departing owner their share.
A home appraisal is usually required to determine market value and ensure a fair equity split.
Refinancing may not be a good option if interest rates have risen since you originally bought the house. In some cases, it’s possible to assume the mortgage from the lender — that is, take full responsibility for the mortgage while removing the existing owner from financial responsibility. Some popular loan types that are assumable include VA loans, FHA loans, and USDA loans.
Keep in mind that the person assuming the loan still has to qualify based on the lender’s credit and income requirements.
If assuming the loan isn’t possible, the co-buyers may choose to sell the home and divide the proceeds. Selling provides a clean financial break and skips the need to restructure the mortgage.
“How the home is titled shapes what happens when someone exits,” Banfield said. “If the co-owners are tenants-in-common, for example, one of the owners can petition a court for partition sale even if others object.”
Joint tenants, on the other hand, usually must agree unanimously before selling. These differences affect each owner’s rights, and all co-buyers should discuss titling options before purchasing a house.
Everyone needs homeowners insurance, including co-buyers. Not only do mortgage lenders require it when you finance a home, but it’s essential to protect against unexpected events like theft, fire, and other damaging incidents.
“The biggest difference when the owners aren’t married is the added financial and legal complexity,” Travis Hodges, managing director at VIU by HUB, said via email. Assuming that the co-owners don’t share finances as a single unit, one person’s missed premium can jeopardize the entire policy.
Co-owners should be listed as “additional insureds” so each person receives full coverage. “An additional insured receives protection under the policy, including coverage for property and liability claims,” Hodges said.
An additional interest, which is easy to confuse with additional insured, does not receive coverage and can’t file claims.
Hodges stresses that all co-buyers should be listed on the homeowners insurance policy. Leaving an owner off the policy can lead to denied claims or policy cancellation. Ensuring ownership documents match the policy protects you and your co-buyers equally.
A written co-ownership agreement is one of the most important tools for protecting both the relationship and the investment. It should outline ownership shares, how much each person contributes to the housing down payment and monthly costs, how you’ll handle repairs, and what happens if someone wants to move or sell. An attorney can help create a clear document that sets expectations from the outset.
Transparency matters. Each co-buyer should be comfortable telling the other about their credit scores, income, existing debts, and savings. This prevents surprises during the mortgage process and gives everyone a realistic sense of how much house they can afford.
It also helps co-buyers understand each other’s financial strengths and vulnerabilities before committing to long-term ownership.
Just like roommates, co-buyers need to align on lifestyle expectations when sharing a home. It’s a tough conversation, but having it now can prevent conflicts later.
Before signing on the dotted line, you and your fellow co-buyer(s) should discuss how you’ll manage noise, guests, cleanliness, pets, shared spaces, and homeownership responsibilities. A frank discussion before you buy can give everyone involved peace of mind down the line.
A consistent and well-organized system for paying shared expenses helps build trust, which is essential when entering into a shared financial obligation, such as co-ownership of a home.
Some co-buyers use a joint bank account for mortgage payments and bills, while others prefer to keep funds separate and pool money monthly. The key is making sure everyone knows what they owe, when payments are due, and how you’ll collectively cover unexpected costs.
Life rarely unfolds as expected, which is why you and your co-buyers should chat about how you’ll handle life’s twists and turns before you buy. This includes job shifts, financial setbacks, adding new household members, or one owner wanting to move. Deciding these details in advance makes transitions easier and lowers the chance of conflict.
Setting aside time once a year to review your co-ownership agreement, shared expenses, repair needs, and long-term goals helps keep everyone aligned. Annual check-ins help owners update plans before minor issues grow into major disagreements.
Co-owning a house can be a good idea for buyers who want to enter the market sooner or reduce individual housing costs. It works best when all owners are financially stable, transparent about expectations, and protected by a written co-ownership agreement. Co-buying can increase affordability and expand buying power, but it also requires strong communication and shared long-term goals.
Co-buying a house works by having two or more people apply for a mortgage loan together, pool funds for the down payment, and jointly take on ownership responsibilities. After choosing how to structure the title, co-buyers share monthly housing expenses and decision making about maintenance, repairs, and long-term plans. Many groups create a co-ownership agreement outlining financial contributions, living arrangements, and what happens if someone wants to move.
A co-ownership home is a property purchased and owned by two or more individuals who agree to share both financial and legal responsibility. Instead of one person covering the whole mortgage, insurance, and upkeep, co-owners divide these costs. You can structure ownership as joint tenancy or tenancy in common, depending on how you want to share rights and equity.
