Buying a House with a Friend: Is Co-Buying the Answer in 2026?

The dream of homeownership has felt increasingly out of reach for a generation of first-time buyers in the UK. Even with interest rates stabilizing and a slight easing in affordability pressures, the gap between average earnings and property prices remains historically wide. For many, the math of buying solo simply doesn’t add up.

But what if you didn’t have to do it alone?

An increasing number of first-time buyers are turning to a non-traditional route: buying a house with a friend or sibling. Recent surveys show that nearly a third (32%) of Brits are now open to co-buying to get onto the property ladder sooner.

Pooling your resources sounds like a brilliant workaround to a tough housing market—and in many cases, it is. However, joint property ownership is also a major legal and financial commitment. Before you start browsing Rightmove with your best mate, here is everything you need to know about the reality of co-buying.

1. The Big Benefits of Co-Buying

The obvious advantage of co-buying is purchasing power. Combining two incomes and two pots of savings fundamentally changes what you can afford.

• A Double-Sized Deposit: Saving a £30,000 deposit on your own can take years. Splitting that target down the middle instantly makes it more achievable.

• Boosted Borrowing Power: Most UK lenders cap mortgages at roughly 4.5 times your annual income. If you earn £35,000, your solo borrowing limit is around £157,500. Combine that with a friend earning the same, and your joint borrowing capacity jumps to over £315,000.

• Access to Better Rates: Lenders offer more competitive interest rates at lower Loan-to-Value (LTV) bands. A larger combined deposit might push you from a 95% LTV mortgage down to a cheaper 85% or 80% product.

• Shared Running Costs: Beyond the mortgage, you’ll be splitting council tax, utility bills, maintenance fees, and building insurance down the middle.

2. Tenants in Common vs. Joint Tenants: The Vital Distinction

When buying a house with a friend, you must choose how you will hold the legal title of the property. In the UK, there are two primary options:

Joint Tenants

Under this agreement, you both own the entire property together. You do not own distinct shares, and you cannot leave your “part” of the property to anyone else in a will. If one owner passes away, their share automatically transfers to the other owner (known as the right of survivorship). This is the standard path for married couples, but it is rarely suitable for friends.

Tenants in Common

This is almost always the correct route for co-buying friends. It allows you to own distinct, unequal shares of the property (e.g., a 60/40 split based on who put in more deposit). Furthermore, you can leave your share to whoever you wish in your will, and the right of survivorship does not apply.

3. The Financial Reality: Joint and Several Liability

Here is the single most important legal reality that most co-buyers overlook: Joint and several liability.

On a joint mortgage, the lender does not see two separate borrowers with 50% shares. Instead, they hold both of you 100% responsible for the entire debt.

⚠️ The Worst-Case Scenario: If your friend loses their job, runs into financial trouble, or simply refuses to pay their share of the mortgage, the lender will not chase them proportionally. They will demand the full monthly payment from you. If the payment is missed, it will damage both of your credit scores equally.

4. Protecting Yourself: The Deed of Trust

To prevent differences of opinion from turning into legal disputes, you must draft a Deed of Trust (sometimes called a Declaration of Trust) through your solicitor.

This legally binding document acts as a pre-nuptial agreement for your home. It lays out exactly what happens in various scenarios, including:

• How the initial deposit was split and how those funds are recouped upon sale.

• Who pays what percentage of the monthly mortgage payments, bills, and unexpected maintenance costs.

• What happens if one of you wants to sell and move out, but the other wants to stay (e.g., offering a first right of refusal to buy the other out).

• An agreed mechanism for valuing the property if one partner wants to exit.

5. The Hidden Catch: Your Future Borrowing Capacity

What most standard property articles skip entirely is how co-buying impacts your future plans.

Imagine that in five years, you want to buy a new home with a long-term romantic partner. Even if your friend is successfully paying their share of your joint property, future lenders will stress-test you against the full outstanding balance of that first joint mortgage, not just your half of it.

This “committed expenditure” can severely limit your ability to secure a second mortgage unless you are completely bought out of the first property. Before jumping in, you and your friend must agree on a clear exit timeline (typically 3 to 5 years).

6. Is Co-Buying Right for You?

If you have a rock-solid friendship, transparent conversations about personal finances, and a bulletproof Deed of Trust, co-buying can be a fantastic springboard onto the property ladder. It stops you from wasting money on rent and allows you to start building equity years earlier than you could alone.

However, if you feel uncomfortable discussing credit scores, debt, or long-term career moves with your friend, it is a sign that co-buying might not be the right path.
