Choose the structure before shopping
Family help can be a non-repayable gift, a documented loan, a guarantee or co-signing arrangement, or direct co-ownership. Lenders and lawyers treat these differently, so decide the structure before relying on a purchase budget.
Document the source of funds
A lender may require bank statements and a signed gift letter confirming that gifted funds are non-repayable. A family loan can affect debt-service calculations. Tell the lender and legal adviser the complete arrangement rather than documenting it after an offer is accepted.
If a parent goes on title
Co-ownership raises questions about beneficial ownership, decision-making, expenses, sale proceeds, creditor exposure, estate planning, family-law claims, property transfer tax, and capital-gains treatment. A written co-ownership agreement can set out contributions and an exit process.
Protect the relationship
Discuss what happens if the buyer wants to sell, refinance, rent the property, add a partner, cannot make payments, or needs more capital. Clarity at the beginning is kinder than relying on shared assumptions.
Whistler-specific checks
Unconventional ownership can interact with employee covenants, rental-pool agreements, hotel-condo financing, GST, and lender restrictions. A pre-approval for a conventional home may not apply to the property type you choose.
The three routes in the original article
How family help can be structured
Each route can improve purchasing power, but responsibility, control, documentation, and tax or estate consequences are different.
1. A gift
Parents provide part of the down payment or purchase price without taking title. It is straightforward for the buyer, but the lender will normally require documentation confirming whether the funds are truly non-repayable.
- Buyer retains ownership control
- No ongoing repayment if it is a true gift
- Parents generally have no property claim
2. A guarantee or co-signing arrangement
The parents’ income, assets, or credit support the mortgage application. This may help approval, but it exposes the parents to the debt if the buyer cannot make payments.
- Can strengthen mortgage qualification
- Creates ongoing financial responsibility
- A default can affect the guarantor’s credit
3. Shared title or parental ownership
Parents go on title and the family agrees how contributions or repayments work. This can preserve an ownership interest but requires careful legal, tax, estate, and exit planning.
- Shared control and sale decisions
- Written repayment and expense terms are important
- Tax and family-law advice may be needed

Frequently asked questions
Quick answers before you go
Does a gifted down payment need paperwork?
Often yes. CMHC guidance notes that a lender may require a signed letter from the family member confirming the purpose of the gift and that it is non-repayable.
Is mortgage pre-approval a guarantee?
No. Final approval still depends on the borrower, the property, valuation, and lender requirements at the time of purchase.
