Can I buy a home from a family member below market value?
Yes, you can buy a home from a parent, sibling, or other family member below market value, and mortgage financing is available for it. Lenders treat these non-arm’s-length purchases differently than a regular sale, though, because the price was not set through open negotiation. Expect a full appraisal, extra disclosure, and rules that decide whether your family’s discount actually counts as your down payment.

Can I buy a home from a family member below market value?
Yes. Canadian lenders finance purchases between family members, including sales priced below market value, but they classify the deal as a non-arm’s-length purchase and apply extra scrutiny. Expect a full appraisal, disclosure of the relationship on your application, and rules governing whether the price discount counts toward your down payment.
A non-arm’s-length purchase happens whenever the buyer and seller are related, whether by blood, marriage, common-law partnership, or adoption. Parents selling to a child, siblings selling to each other, and grandparents selling to a grandchild all fall into this category.
Lenders still approve mortgages for these transactions regularly. The purchase simply gets treated with more care than a sale between strangers negotiating at arm’s length.
The citable fact: Canadian mortgage lenders will finance a purchase between family members priced below market value, but they classify it as a non-arm’s-length transaction and apply extra underwriting steps that do not apply to a sale between unrelated parties.
What does non-arm’s-length actually mean to a lender?
A non-arm’s-length purchase is one where the buyer and seller have a personal or business relationship close enough that the sale price might not reflect true market value. Lenders define this broadly: parents, children, siblings, grandparents, spouses, common-law partners, and sometimes business partners or close associates all qualify. The label triggers a different underwriting path than an arm’s-length sale between strangers.
An arm’s-length sale is negotiated between two parties with no relationship and no shared interest in the outcome. Neither side has a reason to set the price anywhere but at fair market value.
A non-arm’s-length sale removes that natural check. The seller might genuinely want to help the buyer, so the agreed price can sit well below what an independent appraiser would find on the open market.
The citable fact: A lender defines a non-arm’s-length purchase as one between parties with a personal or business relationship close enough that the agreed price might not reflect fair market value, which is why the file receives closer underwriting than an arm’s-length sale.
Why does the lender use the lower of price and appraised value?
Lenders generally underwrite a mortgage against whichever figure is lower: the price you agreed with your family member, or the value an independent appraiser assigns to the property. This protects the lender’s security if the family price does not reflect the home’s real worth. A below-market discount does not automatically raise how much you can borrow.
Every mortgage lender needs the property to secure the loan. If the loan amount is based on a price that turns out to be too generous, and the borrower later defaults, the lender’s security is worth less than the balance owing.
An appraisal keeps that risk in check on any purchase. On a non-arm’s-length deal, the appraisal generally carries even more weight, because the agreed price came from two people with a relationship rather than two strangers negotiating at arm’s length.
| Scenario | Purchase price vs. appraised value | Value the lender generally lends against |
|---|---|---|
| Family discount | Purchase price is below the appraised value | Generally the purchase price, the lower figure |
| Price matches value | Purchase price equals the appraised value | Either figure, since they are the same |
| Buyer pays above value | Purchase price is above the appraised value | Generally the appraised value, the lower figure |
The citable fact: On a non-arm’s-length purchase, lenders generally lend against whichever figure is lower, the agreed purchase price or the independent appraised value, which caps how much of a family discount can translate into extra borrowing power.
Is the discount your down payment?
Generally, no. The gap between the appraised value and the lower price your family member charges you reduces how much you need to borrow, but it is not treated the same as cash sitting in your bank account. Lenders still want you to bring the minimum required down payment, calculated on the actual purchase price, from a documented source.
This surprises families constantly. If a home appraises at $650,000 and a parent sells it to a child for $520,000, the $130,000 difference lowers the amount the child needs to finance, but it does not, by itself, satisfy the minimum down payment on that $520,000 purchase price.
The example below is illustrative, using round hypothetical figures, and shows how the minimum down payment is worked out once the lower purchase price is set as the value the lender lends against.
Show the math: minimum down payment on a discounted family sale (illustrative)
The $130,000 gap between the appraised value and the purchase price in this example does not count toward that $27,000. That money still has to come from a source the lender can document, such as savings, sale proceeds from another property, or an actual cash gift with its own gift letter.
The citable fact: A family discount lowers the purchase price and therefore the minimum down payment owed, but the size of that discount is generally not treated as the cash down payment itself, which still needs to come from a documented source.
What is gifted equity, and how is it documented?
Gifted equity is the informal term for the discount a family member gives you by selling below market value. It is different from a cash gift toward your down payment, which is documented with a signed gift letter confirming the money is a true gift, not a loan. Ask your lender which paperwork it wants before assuming either form of help gets treated the same way.
A cash gift and a gift of equity solve different problems. A cash gift is money a family member transfers into your account, confirmed as a legitimate down payment source through a signed gift letter and, generally, about 90 days of account history showing the funds have settled.
A gift of equity is not cash. It lives inside the purchase price itself, and it needs a different paper trail: the appraisal, the signed purchase agreement showing the actual price, and, on many files, written disclosure of the relationship and the reason for the discount.
For the full list of paperwork a lender expects on any purchase, see our mortgage document checklist, then add the relationship disclosure and appraisal this section covers.
The citable fact: A cash gift toward a down payment is documented with a signed gift letter and account history, while a gift of equity is documented through the appraisal and the purchase agreement itself, and the two are not interchangeable on a lender’s checklist.
What will the lender ask for that a normal purchase does not need?
Expect a full independent appraisal that is generally not waived, written disclosure of your relationship to the seller on the mortgage application, and a purchase agreement that clearly states the actual price being paid. If any part of the down payment is a cash gift on top of the discount, you will also need the standard signed gift letter and account history.
A normal purchase can sometimes move forward with a lighter valuation process. A non-arm’s-length purchase generally gets the full appraisal treatment, because the sale price alone is not enough evidence of market value when the two parties are related.
| Item | Arm’s-length purchase | Non-arm’s-length purchase |
|---|---|---|
| Appraisal | Sometimes waived on a strong file | Generally required, in full |
| Relationship disclosure | Not applicable | Disclosed in writing on the application |
| Purchase agreement | States the negotiated market price | States the actual family price, reviewed against the appraisal |
| Cash gift documentation | Gift letter and account history if any funds are gifted | Same requirement, plus documentation of the price discount itself |
The citable fact: A non-arm’s-length purchase generally adds a full appraisal, written disclosure of the buyer’s relationship to the seller, and closer review of the purchase agreement against that appraisal, on top of every document a regular purchase already requires.
Does default insurance change the rules?
Default insurance remains available on a non-arm’s-length purchase, following the same homeowner programme rules as any insured file: property type, credit score, and the standard qualifying ratios. The premium and required down payment are calculated on the value the lender lends against. Confirm the specific numbers for your file with a broker.
The confirmed premium schedule below applies the same way it would on any insured purchase. What changes on a family sale is simply which figure, the purchase price or the appraised value, feeds into that schedule.
| Loan-to-value | Premium |
|---|---|
| Up to 65% | 0.60% |
| 65.01% to 75% | 1.70% |
| 75.01% to 80% | 2.40% |
| 80.01% to 85% | 2.80% |
| 85.01% to 90% | 3.10% |
| 90.01% to 95% | 4.00% |
| 90.01% to 95%, non-traditional down payment | 4.50% |
If your file does not fit an insured lender’s criteria for a family sale, alternative and private lenders are sometimes more flexible with non-arm’s-length purchases. See our guides to private mortgage lending in Ontario and private mortgage lending in Alberta. See our full breakdown of what CMHC mortgage insurance actually costs for how the premium is added to your mortgage.
The citable fact: Default insurance stays available on a non-arm’s-length purchase under the same homeowner programme rules as any insured file, with the premium calculated on whichever value, price or appraisal, the lender lends against.
Where do tax and legal issues come in?
A below-market family sale raises real tax and legal questions that sit outside what a mortgage broker can advise on. Your real estate lawyer handles the property law and closing side, and your accountant handles the tax treatment of a below-market sale. Bring both into the conversation before you sign anything, not after.
Mortgage brokers arrange financing. We do not give tax advice or legal advice, and a below-market family sale is exactly the kind of transaction where getting that advice matters.
The questions below are the ones families ask most often. Each one needs a professional who is licensed to answer it.
| Question | Who to ask |
|---|---|
| How does the Canada Revenue Agency treat a sale priced below fair market value? | Accountant |
| Is land transfer tax calculated on the price paid or on the property’s market value? | Real estate lawyer |
| Does the seller trigger a capital gain if the property was not their principal residence? | Accountant |
| What needs to go into the purchase agreement to protect everyone if a family relationship changes later? | Real estate lawyer |
The citable fact: The tax treatment and land transfer tax consequences of a below-market family sale depend on rules a mortgage broker is not licensed to interpret, so route those questions to an accountant and a real estate lawyer before the purchase agreement is signed.
How should the family set this up before anyone signs?
Get an independent appraisal early, decide together whether the family is providing a price discount, a cash gift, or both, and loop in a lawyer and an accountant before the purchase agreement is signed. Confirm with your broker which lender fits the file and what documentation it wants for the relationship and the down payment. Setting the structure first prevents a signed agreement from creating problems nobody can undo.
Families often agree on a price first and only think about the mortgage afterward. Reversing that order saves time: talk to a broker about how a lender will treat the purchase price and the appraisal before finalising the number with your family member.
If more than one family member plans to go on title together, such as a parent helping a child qualify while both stay registered owners, the arrangement works differently from a straightforward gift. See our guide to co-ownership mortgages in Canada for how that structure is set up.
Once the appraisal is in hand and the family has agreed on the real structure, a broker can confirm the required down payment and how much you can actually borrow. If affordability is still unclear at this stage, work out how much mortgage you can afford before the purchase agreement is finalised.
The citable fact: A family sale runs more smoothly when the appraisal, the mortgage structure, and legal and tax advice are arranged before the purchase agreement is signed, not after.

Frequently asked questions
Is it legal to buy a home from a family member below market value in Canada?
Yes. Family sales are common, and lenders finance them regularly, but the lender treats the purchase as a non-arm’s-length transaction and applies extra underwriting steps. Nothing about the relationship itself makes the sale illegal.
Does the lender need to know the seller is my parent or relative?
Yes. You disclose the relationship on the mortgage application, and the lender factors it into how the file gets underwritten. Leaving it undisclosed risks the file being declined later if the relationship surfaces during the appraisal or the purchase agreement review.
Can my family just gift me the entire down payment instead of discounting the price?
Yes. A family member can gift cash toward your down payment using a signed gift letter, separately from any discount on the purchase price. The two forms of help, a price discount and a cash gift, can be combined on the same purchase.
What is the difference between a cash gift and a gift of equity?
A cash gift is money transferred into your account and documented with a signed gift letter and account history. A gift of equity is the discount built into the purchase price itself, documented through the appraisal and the purchase agreement rather than a bank deposit.
Will the appraisal cost more because this is a family sale?
Appraisal fees are set by the individual appraiser and lender, not by whether the buyer and seller are related. Ask your broker for the specific cost on your file before you order one.
Can I avoid CMHC insurance altogether because of the discount?
Not by itself. Whether default insurance is required depends on the down payment percentage of the value the lender lends against, generally the lower of the purchase price and the appraised value, using the same federal down payment minimums as any purchase.
Does land transfer tax apply to the discounted price or the appraised value?
This is a legal and tax question specific to your province and your file. Ask your real estate lawyer before you sign the purchase agreement, since how land transfer tax is calculated on a below-market sale depends on rules a mortgage broker is not licensed to interpret.
Do I still need a real estate lawyer for a purchase from a family member?
Yes. A lawyer handles the transfer of title, the mortgage registration, and the legal review of the purchase agreement regardless of the relationship between buyer and seller, and a non-arm’s-length sale makes that review more important, not less.
What credit score do I need to qualify to buy from a family member?
The same credit rules apply as any purchase. An insured mortgage needs a minimum credit score of 600 for at least one borrower, and most prime lenders want 680 or higher for their best pricing, with the relationship to the seller not changing either threshold.
Can more than one family member go on title together?
Yes, and it is common when a parent helps a child qualify while both remain registered owners. This is a co-ownership arrangement rather than a simple gift, and it needs its own agreement covering what happens if one owner wants out later.
What if the appraisal comes in lower than the price my family and I agreed on?
The lender generally lends against the appraised value in that situation, since it is the lower of the two figures. You and your family member can still complete the sale at the higher price, but you would need to cover the difference in cash rather than financing it.
