Lending Her Daughter the Down Payment Shortfall in Oakville

The situation

Minh had spent twenty years working as an insurance adjuster, and she had watched enough files go sideways to know that good intentions do not protect anyone once money changes hands. Her daughter Grace, a court clerk, had found a townhouse in Oakville listed at roughly $650,000 — her first home, bought on her own. Grace's savings and the mortgage her bank was prepared to offer covered most of it, but left a gap of about $90,000. Minh wanted to close that gap herself rather than watch Grace stretch into a mortgage that would leave her with nothing left over each month.

What Minh did not want was to simply hand over $90,000 and call it a gift. She had seen enough family money disappear into relationships, renovations and life changes to want the option of being repaid if circumstances changed. She came to Treadstone Law asking for something specific: she wanted the loan structured as an actual private mortgage, registered against the property, with real terms — not a verbal understanding between mother and daughter that everyone assumed would be honoured.

A private mortgage works like any other mortgage in principle. It is a loan secured against real estate, registered on title, with the lender able to enforce repayment the same way a bank could if the borrower defaults. What made this file more involved than it first appeared was that Grace's own bank was also lending on the same property, and a bank does not simply let a second loan appear on title without knowing about it.

What the underwriting required

Before any private mortgage is registered, our team's first question is always the same: does the buyer's primary lender know about it, and does it allow it. Grace's mortgage approval had already gone through underwriting based on her income, her savings, and the down payment she disclosed. A private second mortgage changes that picture. It adds a new debt obligation, and it changes how much of the property Grace actually owns free and clear if something goes wrong.

Most mortgage lenders require any secondary financing to be disclosed before closing, and many restrict it outright or attach conditions to allowing it. Grace's bank was no exception. Once we raised the private mortgage with her mortgage broker, the bank required three things before it would proceed: written disclosure of the second loan and its terms, a postponement agreement confirming the bank's mortgage would keep priority over Minh's in the event of a default, and proof that Grace could still service both debts under the bank's own qualification rules.

That last condition mattered more than anyone expected going in. Minh had originally pictured the loan as flexible and informal between family — no fixed payment schedule, interest-free, repaid whenever Grace was able. A bank calculating whether a borrower can afford a property does not work that way. Once a second mortgage exists, its payments count toward Grace's total debt load for qualification purposes, and a loan with no fixed payment and no stated interest rate cannot be plugged into that calculation at all. To get the bank's approval to proceed, the private mortgage needed a real interest rate and a real repayment schedule, on paper, whether or not Minh ever intended to collect on it strictly.

There was a second issue sitting underneath the first. Early in the file, Grace and Minh had discussed simply not mentioning the loan to the bank at all, treating the $90,000 as if it were part of Grace's own savings. That is a serious problem, not a shortcut. Misrepresenting the source of funds to a mortgage lender is a form of fraud against that lender, regardless of the family relationship behind the money, and it can put the entire mortgage — and the closing — at risk if discovered later. We were direct with both of them that this was not a workable path, and the file moved forward on the basis of full disclosure from that point on.

What we did

1. Confirmed our firm could only act for Minh. A lawyer generally cannot represent both the lender and the borrower in the same private mortgage transaction, even within a family, because their interests are not the same and can conflict — over interest rate, repayment terms, and what happens on default. We acted for Minh only, as the lender.
2. Required Grace to obtain independent legal advice. Grace retained her own lawyer, Cristina, to advise her separately on the mortgage terms before she signed. Independent legal advice protects everyone: it gives Grace a genuine understanding of what she was agreeing to, and it protects the loan itself from a later claim that Grace signed under family pressure without knowing what she was signing.
3. Disclosed the private mortgage to the bank in writing. We coordinated with Grace's mortgage broker to put the second loan on the record before closing, rather than leaving it to surface afterward, and confirmed in writing what the bank required to consent to it.
4. Negotiated the postponement agreement. The bank's first mortgage needed to keep priority over Minh's loan. We reviewed and negotiated the postponement so Minh understood exactly what it meant for her: if Grace ever defaulted and the property had to be sold, the bank would be repaid in full before Minh saw a dollar.
5. Built a repayment schedule the bank's underwriting could accept. We worked with the mortgage broker to set an interest rate and monthly payment that satisfied the bank's debt service calculation without stretching Grace's budget past what she could actually manage alongside her primary mortgage.
6. Registered the mortgage properly against title. The loan was registered as a second mortgage in the correct priority position, with a promissory note and standard mortgage terms covering default, discharge, and what happens if Grace sells or refinances before it is repaid.

The outcome

The purchase closed with Grace's bank mortgage in first position and Minh's private mortgage in second, both properly registered and both fully disclosed. Grace bought the Oakville townhouse on her own, as planned, with the shortfall covered by her mother rather than a larger primary mortgage she would have struggled to qualify for.

Neither side got exactly what they had first wanted, and that is the honest measure of how this file resolved. Minh had hoped to lend the full $90,000 informally, interest-free, on no fixed schedule. To satisfy the bank's qualification rules, the loan had to carry a stated interest rate and a real monthly payment, which meant Grace now owed her mother a fixed amount every month rather than an open-ended favour — a change in the texture of their relationship that Minh had not fully anticipated, even though she was the one who had asked for it to be documented properly in the first place. The postponement agreement also meant Minh's protection was real but limited: if Grace ever defaulted, the bank would be paid first, and Minh's second mortgage would only recover whatever equity was left.

Grace, for her part, took on a second, smaller debt with fixed payments in addition to her primary mortgage, and paid for her own independent legal advice on top of the private mortgage's registration costs — expenses that would not have existed if the loan had stayed an informal family arrangement. What she gained was a mortgage on paper that was enforceable, disclosed, and unlikely to cause problems if she ever needed to sell, refinance, or if her relationship with her mother changed in ways neither of them could plan for.

The compromise held because both sides could see what they were actually trading. Minh gave up flexibility and informality in exchange for a legally enforceable claim on the property and a bank that would not treat her loan as a hidden problem waiting to surface. Grace gave up the simplicity of an undocumented family gift in exchange for a mortgage that would not put her own bank financing, or her mother's money, at risk down the line.
