Co-Buying a Home With Family or Friends in Burnaby in 2026

I've written more than one offer this year where the buyers weren't a couple. A sister and brother splitting a townhome. A mother helping her son onto title. Two friends who decided a shared mortgage beat two separate rents. None of them asked me if this was normal. I think it already is.

With Burnaby prices still well above what a single median income can carry, pooling resources with someone you trust is a sensible move. But co-buying isn't the same transaction as buying alone, and the parts that go wrong usually aren't the parts anyone thought to ask about before removing subjects. Here's how ownership works in BC, what a co-ownership agreement should cover, how lenders view joint applicants, and why you plan your exit before you have the keys.

Two ways to hold title, and they are not interchangeable

In British Columbia, when two or more people buy a property together, the title lists them as either joint tenants or tenants in common. The difference isn't paperwork trivia. It changes what happens to the property the day one owner dies.

Joint tenancy gives every owner an equal, undivided interest in the whole property, with a right of survivorship. According to BC's Land Title and Survey Authority, when a joint tenant dies, their interest passes automatically to the surviving owners, bypassing that person's estate and will entirely. It's the structure most spouses use, precisely because it avoids probate on the family home.

Tenancy in common lets each owner hold a defined share of the property, equal or not (a 60/40 split between a parent and adult child, for example). There's no right of survivorship. If an owner dies, their share goes into their estate and passes according to their will, not automatically to the other co-owners. Under BC's Property Law Act, this is actually the legal default: unless your transfer documents say "joint tenants" outright, the law presumes tenants in common with equal shares.

For most people buying with a sibling, a friend, or a parent who isn't a spouse, tenancy in common is the better starting point, since it lets your share go where you choose rather than automatically to your co-owner. This is where a bit of legal advice up front beats a costly correction later. Your conveyancing lawyer will ask which structure you want, so walk in with an answer.

Why a co-ownership agreement matters more than the mortgage

The purchase contract gets everyone to the closing table. It says nothing about what happens later when one owner wants out or stops paying their share. That's the job of a separate co-ownership agreement, the document non-married co-buyers skip most often.

A solid agreement, reviewed by a real estate lawyer before you write an offer, typically covers:

• Who contributes what to the down payment, since contributions rarely match a clean 50/50 title split
• How ongoing costs split: mortgage, tax, insurance, strata fees, repairs, and who covers a shortfall if someone misses a month
• What happens if one owner wants to sell and the others don't, including a buyout formula and how the property gets valued
• What happens on death, separation, job loss, or another major change nobody planned for

People's Law School, a BC non-profit legal education organization, runs a public webinar on exactly this topic, covering what happens when a co-owner wants to sell and others don't, and what happens to the mortgage if someone leaves. Their guidance matches what I see in practice: put the agreement in writing before you're financially tied to the property, not after a disagreement starts.

How lenders actually look at joint applicants

Most Canadian lenders will qualify multiple applicants on one mortgage and combine incomes, often the whole reason co-buying makes sense: two moderate incomes can qualify for a home neither could carry alone. But every applicant is typically held jointly and severally liable for the full loan, not just their share. If your co-owner misses a payment, the lender can come after you for the whole amount, and it can show up on your credit even if you never missed one yourself.

Lenders also weigh each applicant's individual credit and debt, so one co-buyer with a thin file or heavy debt load can affect the rate or approval for the group. Get pre-approved individually before you shop together, so nobody discovers a credit surprise mid-negotiation. My mortgage calculator is a reasonable starting point for modeling what a combined income can carry, though your real approval comes down to underwriting, not an online estimate.

One detail people forget: a mortgage default follows the loan, not the title split. Title tells the world who owns what; the mortgage tells the bank who's on the hook. Make sure you understand where those two diverge before you sign either one.

Plan the exit before you need one

Every co-ownership arrangement ends eventually: someone gets married, moves for a job, wants to cash out, or just changes their mind. The buyers I've seen struggle most treated the exit as a future problem instead of a today decision.

Settle these before you write an offer:

• If someone wants out in year two, do the remaining owners have first right to buy their share, and at what price?
• If nobody can afford to buy the other out, are you prepared to sell and split proceeds?
• Is there a minimum holding period, so nobody can force a sale six months after closing?

If you're looking at newer inventory built with this kind of flexibility in mind, Edmonds has become one of Burnaby's more interesting pockets for it. It's added a wave of new townhomes and multiplex units near the SkyTrain, with layouts that increasingly suit two households sharing one address.

Key Takeaways

• BC recognizes two ways to co-own a home: joint tenancy (equal shares, automatic right of survivorship) and tenancy in common (defined shares, no survivorship, passes through your estate).
• Tenancy in common is the legal default in BC unless your transfer documents specifically state joint tenancy.
• A written co-ownership agreement, reviewed by a lawyer, should cover contributions, ongoing costs, buyout terms, and what happens on death, separation, or default.
• Lenders typically hold all applicants jointly and severally liable for the full mortgage, so one co-buyer's credit or missed payment can affect everyone.
• Plan your exit terms (buyout rights, appraisal process, minimum holding period) before you write an offer, not after a disagreement starts.

Frequently Asked Questions

Can friends who aren't married or related buy a home together in BC?

Yes. There's no legal restriction on who can co-own property in BC. Friends and siblings buy together regularly, usually as tenants in common so each person's share passes according to their own will rather than automatically to the other owners.

What's the difference between joint tenancy and tenancy in common in BC?

Joint tenancy gives all owners an equal, undivided share and a right of survivorship, so a deceased owner's interest passes automatically to the survivors. Tenancy in common lets owners hold defined, unequal shares with no survivorship; a deceased owner's share passes through their estate instead. BC's Property Law Act presumes tenancy in common unless the documents say otherwise.

Do we need a lawyer for a co-ownership agreement, or can we write it ourselves?

I'd strongly recommend a real estate lawyer draft or review it. A lawyer will tailor the buyout formula and exit terms to your situation, and catch conflicts between your agreement and your mortgage that a template can't anticipate.

If one co-owner's credit is weak, does that affect the whole mortgage application?

It can. Lenders assess each applicant's credit and debt individually, and weak credit on one application can affect the rate or amount approved for the group. Get pre-approved separately before you house hunt together.
