Here’s What That Means for You.
A few years ago, buying a home with someone outside of marriage was the exception. Today, it’s fast becoming the rule.
According to the National Association of Realtors, roughly 30% of all U.S. home sales now involve co-buyers. Around 32% of Gen Z buyers say they’re actively considering co-buying real estate with a friend, family member, or partner. The median age of a first-time buyer just hit a record high of 40.
Co-buying isn’t a workaround anymore. It’s how a growing number of people are getting into the market at all, and the ones who do it right are treating it like investors, not optimists.
This is worth understanding whether you’re already planning to buy with someone or just starting to wonder if it makes sense.
The Numbers That Actually Matter
Median home prices have risen roughly 15% year-over-year. Mortgage rates have held in the 6.5–7% range. Around half of aspiring buyers cite student loan debt as a reason they haven’t purchased yet.
Put those together and the math stops working for a lot of people trying to buy on one income.
Co-buying real estate is the direct response. When two or more people pool income, they improve their debt-to-income ratio, hit the 20% down payment threshold faster, and split carrying costs in a way that can make ownership competitive with renting.
Research from CoBuy puts the number of Americans who already co-own property with a non-spouse at around 61 million, up approximately 3 million in a single year. This is no longer a workaround. It’s a deliberate strategy being used at every income level, in every state, across every demographic.
Who Is Co-Buying Today (And Why It’s Not Who You Think)
The popular image of co-buying is an unmarried couple pooling resources to get into a starter home. That version exists, but it’s no longer the dominant one.
Friends now represent roughly 58% of all co-buying groups, up from 49% in 2021. Multi-generational households are accelerating. Single women, who make up about 25% of first-time buyers, are increasingly co-buying with friends or family members to access neighborhoods one income couldn’t reach.
The average co-buying group is now 3.6 people. Buyers are getting creative about what “buying a home with a partner” actually means.
Co-buying isn’t concentrated in high-cost coastal cities, either. It’s happening across all 50 states, in mid-sized markets, in places where prices haven’t gone completely sideways. The affordability pressure is broad, and so is the response.
What Most Buyers Get Wrong About Shared Homeownership
The biggest misconception is that the hard part is getting the deal done. It isn’t. The hard part is everything that happens after you close, especially when something you didn’t plan for shows up.
Mistake #1: Assuming the relationship is the protection.
Two people who trust each other completely can still end up in a legal dispute over a shared property. Not because they stopped trusting each other, but because they never defined what “fair” meant when one of them needed to sell early, lost their job, or wanted to renovate and the other didn’t.
Around 73% of co-ownership failures that became public disputes had no written agreement in place. A handshake isn’t a co-ownership agreement. It’s a gap in your legal protection.
Mistake #2: Qualifying for more than makes sense.
Two incomes improve purchasing power. But a lot of co-buyers use that expanded power to reach for more house than either person would have bought on their own. Then they’re both exposed if one income disappears.
The right question isn’t “what can we qualify for?” It’s “what can we cover if one of us loses income for six months?” Most people skip this because the numbers look comfortable at signing. That’s exactly when you need to pressure-test them.
Mistake #3: Treating the property like a lifestyle choice instead of a long-term hold.
Location and property type matter more in shared ownership, not less, because exits are more complicated. If you ever need to sell your share, you’re selling into a narrow market. That limits your leverage.
Choose a property with genuine demand and flexibility. Think in 5–10 year terms, not about what feels right today.
Mistake #4: Skipping the hard conversations to avoid tension before closing.
Before buying a home with a partner, you need to know their credit score, their actual income stability, how much debt they carry, and what their situation looks like in two years.
If that conversation is too uncomfortable before you sign, it will be worse after something goes wrong.
What Experienced Co-Buyers Do Differently
People who have done this before follow a specific sequence. It’s not complicated. It just requires doing things in an order most buyers skip.
They define the exit before they define the entry.
Before making an offer, they establish: what happens if one person wants out? Who buys the other person’s share first? At what price? On what timeline? A right of first refusal and a buyout formula aren’t hostile provisions. They’re what make a clean exit possible without litigation.
Court-forced partition sales can run $75,000 or more and take 18 months. That outcome is almost always avoidable when terms are set before closing.
They choose an ownership structure with intention.
Tenants in Common lets each person own a specific percentage, which can be unequal, with the ability to sell their share independently. Joint Tenancy with Right of Survivorship means equal ownership and automatic transfer to surviving co-owners at death. These determine what happens to your equity in a buyout and whether your stake ends up in probate. Choose the one that fits your actual situation.
They document the agreement.
A full agreement covers ownership percentages, down payment contributions, how ongoing costs are split, repair responsibilities, decision-making rules, dispute resolution, and exit terms. Traditional attorneys charge $10,000 to $15,000 for this. Pairgap’s Real Estate Prenup Builder gives co-buyers a structured way to document the same ground from the start.
They set recurring check-ins.
Quarterly or semi-annual reviews of the finances and each co-owner’s plans are how you catch drift before it becomes a dispute. Most co-ownership problems escalate because no one talked about what was changing until it was already a crisis.
Practical Readiness Framework: Before You Start Looking
Work through this before you look at a single listing.
Financial readiness (for each person):
- Actual take-home income, not just gross salary
- Credit score, and anything pulling it down
- Total debt load (student loans, car payments, existing obligations)
- Down payment contribution amount
- Months of reserves each person can cover independently
Partnership readiness (together):
- Agreed purchase timeline
- Location logic based on long-term demand and livability, not just preference
- What happens if one person wants to sell in three years and the other doesn’t
- What happens if one person loses their job
- How financial decisions get made when there’s disagreement
Before you make an offer:
- Choose an ownership structure and document it
- Set the buyout formula and right of first refusal terms in writing
- Use a Co-Buying Power Calculator to get a clear picture of what the combined numbers actually support
Key Takeaways
Co-buying isn’t a compromise. For a lot of buyers in this market, it’s the most rational path to ownership available. But the strategy only works if you treat it like one.
The co-buyers who come out ahead aren’t the ones who had the most trust going in. They’re the ones who did the work upfront so that trust didn’t have to carry the whole weight when circumstances changed.
Plan the exit first. Pressure-test the finances. Get the agreement in writing. Everything else is just shopping.
