Buying With a Family Member
Combining incomes and down payments makes ownership achievable for a lot of people who couldn’t manage it alone. It also creates obligations that outlast the goodwill they were built on — which is why the structure matters as much as the approval.
The thing people get wrong: a co-signer is not a reference or a backup. If the payments aren’t made, the lender can hold them responsible — and the debt counts against their own borrowing ability in the meantime. That’s worth understanding before anyone signs, not after.
The answers in this centre
- My parents want to help me buy. Do they have to be on the mortgage?
- What’s the difference between a co-signer and a co-borrower?
- If my parents co-sign, will it affect their own borrowing ability?
- Can siblings or friends buy a property together?
- What happens if one of us wants to sell later and the other doesn’t?
Three structures, three very different commitments
| Structure | On title? | What it commits them to |
|---|---|---|
| Gift | No | Nothing — a gift letter confirms it isn’t repayable |
| Co-signer / guarantor | Varies | Full legal responsibility for the mortgage |
| Co-borrower | Yes | Ownership and full responsibility |
Title and ownership requirements vary by lender and structure, so it’s worth reviewing with both the lender and a real estate lawyer before anyone commits.
