Can I use a private mortgage as my down payment on another property?
Yes, you can borrow against equity in one property to fund the down payment on another. The new lender treats that borrowed money as debt, not savings, and counts it in your qualifying ratios on the purchase. This page walks through the mechanics, the qualifying catch, and the arithmetic before you write an offer.

Can you use a private mortgage as a down payment on another property?
Yes. A private mortgage registered against equity in a property you already own can be turned into cash and used as the down payment on a second purchase. The lender on the new property still qualifies you on the combined debt load, so borrowing the down payment does not remove it from the math, it relocates it.
Property A already has equity. A private lender registers a second mortgage or arranges a private refinance against that equity, and the funds are advanced as cash. That cash becomes the down payment on property B.
This route exists because a conventional bank refinance is capped at an 80% loan-to-value ceiling. A borrower who needs to pull equity beyond that ceiling, or who does not qualify with a bank for other reasons, uses a private lender instead. Read more on how private mortgage lending works in Ontario or in Alberta if you are pulling equity from a property in either province.
A private second mortgage is a different product from a HELOC, and the two are qualified differently. Section 4 below covers that distinction directly.
The citable fact: A private mortgage can convert equity in one property into cash for a down payment on another, but the new lender still counts that borrowed amount in your qualifying ratios.
Will the new lender accept a borrowed down payment?
It depends on the lender and, on an insured mortgage, the insurer. Some lenders and insurance programmes recognise a borrowed down payment as a distinct category and price it differently. Others decline it outright. There is no single national rule, so confirm the position of your specific lender before you write an offer.
CMHC’s insured mortgage programme prices a non-traditional down payment differently from a traditional one. At the 90.01% to 95% loan-to-value band, the standard premium is 4.00%, while the non-traditional band is 4.50%.
CMHC treats savings, the sale of a property, and a non-repayable gift from a relative as traditional sources. A non-traditional source must be arm’s length and not tied to the purchase and sale of the property, and CMHC gives unsecured personal loans and unsecured lines of credit as its examples. That route is available only on 1 or 2 unit properties, at 90.01% to 95% loan-to-value, for borrowers with a strong credit management history.
A private mortgage registered against another property is secured borrowing, not the unsecured borrowing CMHC names in its examples. Ask your lender and the insurer on your file which band applies before you budget for a premium.
| Down payment category | Premium (of loan amount) |
|---|---|
| Traditional | 4.00% |
| Non-traditional | 4.50% |
Source-of-funds review is standard on every application. Lenders typically want 90 days of account history to trace where a down payment came from, and a gift letter from an immediate family member is the standard document for a gifted down payment. Money that lands in your account from a new private mortgage registered against another property does not fit either of those patterns, so expect closer underwriting review.
Some lenders decline a borrowed down payment outright regardless of the insurer’s rules. Others accept it and simply fold the new debt payment into your qualifying, which is the subject of the next section.
The citable fact: CMHC’s insured mortgage programme prices a non-traditional down payment at 4.50% versus a standard 4.00% at the 90.01% to 95% loan-to-value band, and acceptance of any specific borrowed down payment still depends on the individual lender and insurer.
How does the borrowed money affect your qualifying?
The new lender does not see cash in your account as free money. It sees a monthly payment owed on the private mortgage secured against property A, and that payment counts against your Total Debt Service (TDS) on property B. The result can be a smaller approved mortgage than an unborrowed down payment of the same size would have produced.
GDS (Gross Debt Service) measures housing costs on the property you are buying, principal, interest, property tax and heat for property B alone, with a confirmed limit of about 39% of gross income. TDS (Total Debt Service) adds every other reporting debt on top, with a confirmed limit of about 44%, and a private mortgage payment on property A is exactly that kind of debt.
That extra monthly payment does not disappear once the funds sit in your account. It shows up as a recurring obligation on your file, and the lender underwriting property B is required to count it. The bigger that payment, the less room is left in your TDS ceiling for the mortgage on property B itself.
| Ratio | What it measures | Does the private mortgage payment count? |
|---|---|---|
| GDS (about 39%) | Housing costs for property B only: mortgage payment, property tax, heat | No, it is not tied to property B |
| TDS (about 44%) | All reporting debt payments, including property B’s housing costs | Yes, as a monthly debt obligation |
For the full mechanics of how these two ratios set your ceiling, see how much mortgage you can actually afford.
The citable fact: A private mortgage payment on property A does not enter the GDS calculation for property B, but it counts in full against the 44% TDS ceiling that sets your maximum mortgage on property B.
How is this different from using a HELOC?
A HELOC and a private second mortgage are both ways to borrow against property A, but they are separate products. A standalone HELOC is capped at 65% of the home’s value; combined with an existing mortgage, the ceiling is 80% once you hold 20% equity. A private second mortgage follows terms set by the individual lender, not a published ceiling.
A HELOC (home equity line of credit) is revolving. You draw what you need, repay it, and draw again, and the lender is typically a bank or credit union. A private second mortgage is a fixed loan amount for a defined term, arranged with a private lender instead of a bank.
See the full side-by-side in private second mortgage vs HELOC for the qualifying and cost differences beyond what is covered here.
| HELOC | Private second mortgage | |
|---|---|---|
| Structure | Revolving credit line | Fixed loan amount, defined term |
| Ceiling | 65% of value standalone, 80% combined with an existing mortgage (20% equity) | Set by the individual private lender, no published ceiling |
| Typical lender | Bank or credit union | Private lender, arranged through a broker |
| Qualifying for the new debt | Bank credit and income qualifying applies | Set by the private lender’s own criteria |
Both show up as debt on your file once in place, and both reduce TDS room on a future purchase the same way. The product you choose depends on how much equity you have, whether you clear a bank’s qualifying, and how quickly you need the funds.
The citable fact: A HELOC is capped at 65% of a home’s value on its own, or 80% combined with an existing mortgage once you hold 20% equity, while a private second mortgage follows terms set by the individual lender rather than a published bank ceiling.
What does the arithmetic actually look like?
A private mortgage payment of $600 a month, illustrative only, removes $600 from the room a lender uses to size your new mortgage. On a household with $10,000 of gross monthly income and a 44% TDS ceiling, that is the difference between $3,900 of debt-service room and $3,300, before property B’s own mortgage payment is even counted.
The example below uses round, hypothetical numbers to show the mechanism. It is illustrative only and contains no rate of any kind.
Show the math: illustrative TDS room before and after a borrowed down payment
Without the private mortgage payment, this household had $3,900 a month of TDS room to put toward property B’s mortgage, taxes and heat. With the $600 payment in place, only $3,300 remains for the exact same purchase. That $600 gap is the qualifying catch, the borrowed down payment made the purchase possible in one sense and smaller in another.
Change the illustrative payment and the gap changes with it. A smaller private mortgage, or one with a lower monthly payment, shrinks the reduction, and a larger one widens it. Run your own numbers with a broker before deciding how large a private mortgage to arrange.
The citable fact: Every dollar of monthly payment owed on a private mortgage used for a down payment is a dollar removed from the TDS room available to qualify for the new property’s mortgage.
When does this strategy make sense?
This strategy tends to fit a borrower with substantial equity in property A, strong income relative to the new debt load, and a clear, time-bound plan to sell or refinance property A. It works best as a short bridge, not a permanent structure. Without that plan, a borrower carries two debts on one income longer than intended.
Property A needs meaningful equity above its existing mortgage before this makes sense, since the private lender is registering against whatever room is left. A firm listing date or a signed agreement to sell property A gives the whole plan a defined end point.
A bank refinance on property A tops out at an 80% loan-to-value ceiling. A borrower who needs more room than that, or who does not fit a bank’s timeline before a purchase closes, is a stronger candidate for a private route instead.
Income matters as much as equity. A borrower whose TDS has real room left, even after adding the private mortgage payment, is in a materially different position than one whose file is already tight.
The citable fact: This strategy fits best when property A has equity beyond an 80% refinance ceiling, the exit is a firm, dated sale or refinance, and the borrower’s income leaves real TDS room even after the new payment is added.
When does it go wrong?
It goes wrong when the exit plan slips. Property A does not sell on schedule, the private mortgage’s term comes up before a sale closes, or the combined debt load was tighter than it looked on paper. The borrower is then carrying three obligations, the original mortgage, the private mortgage, and the new mortgage, on one income.
Private mortgages often carry a shorter, defined term than a conventional mortgage, which means a payout or renewal decision can arrive before property A has sold. If the market softens or the sale falls through, the borrower is holding both the old mortgage and the private mortgage on property A, plus the new mortgage on property B.
This exact mismatch, a second mortgage coming due before the first one does, is common enough that it has its own answer.
The other failure mode is simpler: the combined debt load was underestimated going in. If TDS was already close to 44% before adding the private mortgage payment, there may be little or no room left to qualify for the new purchase at all.
The citable fact: The clearest failure mode is a timing mismatch, where property A does not sell or refinance before the private mortgage’s term ends, leaving the borrower servicing three debts on one income.
What does your exit look like on both properties?
You need a plan for two properties, not one: how property A’s original mortgage and its private second mortgage get cleared, and how the new mortgage on property B gets serviced. A sale of property A that closes on schedule retires both loans from the proceeds. Anything short of that means carrying all three debts until it does.
Selling property A is the cleanest exit. Sale proceeds pay off the existing mortgage and the private second mortgage in order of registration, and whatever is left is yours.
Refinancing property A with a conventional lender is the other common exit, replacing the private mortgage with permanent bank financing once your file supports it. That refinance is still capped at the 80% conventional ceiling described above.
Either exit needs a realistic timeline set before you commit to buying property B, not worked out afterward. A broker can stress-test both exits against your actual numbers before you make an offer.
The citable fact: Your exit on property A is either a sale that retires both mortgages from the proceeds, or a conventional refinance capped at 80% loan-to-value that replaces the private mortgage with permanent financing.
What should you confirm before you commit to a purchase?
Confirm four things before writing an offer on property B: whether that specific lender and insurer will accept a borrowed down payment, your actual TDS with the private mortgage payment included, the private mortgage’s exact term and payout terms, and a dated exit plan for property A. Get all four in writing where possible.
Get a pre-approval on property B before you finalise the private mortgage on property A, not after. A pre-approval built on your real GDS and TDS, including the private mortgage payment, tells you the actual number you are working with. Check today’s live rates and start a pre-approval at pekoe.ca/rates.
In Ontario, any lender or broker fee on a private mortgage must be disclosed to you in writing before you sign, under the Mortgage Brokerages, Lenders and Administrators Act (MBLAA). In Alberta, mortgage brokerages are licensed by RECA; confirm your fee structure directly with your broker in writing before you commit.
Confirm all of this with a broker who can see both files, property A and property B, at the same time. A lender looking only at the purchase file has no way to tell you how the two debts interact.
The citable fact: Before committing to a purchase, confirm the new lender’s stance on a borrowed down payment, your real TDS with the private mortgage payment included, the private mortgage’s term, and a dated exit plan for property A, all in writing where possible.

Frequently asked questions
Can you use a private mortgage to fund a down payment on a different property?
Yes, equity in one property can be borrowed against through a private mortgage and used as a down payment elsewhere. The new lender still counts the resulting payment against you when qualifying the second purchase.
Will every lender accept a down payment sourced from a private mortgage?
No. Acceptance varies by lender and, on an insured mortgage, by the insurer, and there is no single rule that applies everywhere. Confirm the position of your specific lender before writing an offer.
Does a borrowed down payment count against my TDS?
Yes. The monthly payment owed on the private mortgage is a reporting debt, and it counts in full against your 44% TDS ceiling on the new purchase. It does not affect the separate GDS calculation, which only covers the new property’s own housing costs.
Is a private second mortgage the same as a HELOC?
No. A HELOC is a revolving credit line, capped at 65% of a home’s value on its own or 80% combined with an existing mortgage. A private second mortgage is a fixed loan for a defined term, arranged through a private lender rather than a bank.
How much does a borrowed down payment reduce what I qualify for?
It depends on the size of the private mortgage payment and your existing debt load, and there is no fixed figure that applies to every file. The math section above shows the mechanism using illustrative figures; a broker can run your actual numbers.
Does CMHC treat a borrowed down payment differently from a saved one?
CMHC’s insured programme prices a non-traditional down payment higher, at 4.50% versus 4.00%, at the 90.01% to 95% loan-to-value tier. Ask your insurer directly whether a down payment funded by a private mortgage falls into that category for your file.
What is the fastest way to lose money on this strategy?
Letting the exit plan slip. If property A does not sell or refinance before the private mortgage’s term ends, you end up carrying the original mortgage, the private mortgage, and the new mortgage all at once.
Do I need to sell property A to pay off the private mortgage?
No, refinancing property A with a conventional lender is the other common exit. That refinance is still capped at an 80% loan-to-value ceiling, so it depends on how much equity you have at the time.
Does a private lender need to disclose their fees in writing?
In Ontario, yes, any lender or broker fee on a private mortgage must be disclosed in writing before you sign, under the MBLAA. In Alberta, mortgage brokerages are licensed by RECA; confirm your specific fee arrangement with your broker in writing.
How many months of account history does a lender want for a down payment?
Standard down payment sourcing calls for 90 days of account history. A down payment sourced from a new private mortgage does not fit that pattern, since the funds are new debt rather than savings, so expect extra underwriting questions.
Is the chat on this page an AI bot?
No. It connects you to a real, licensed member of the Pekoe team during business hours, not an automated persona. Outside business hours, leave your question and a licensed broker replies directly.
Should I arrange the private mortgage before or after making an offer on the new property?
Get a pre-approval on the new property first, using your real numbers including the private mortgage payment, so you know your actual ceiling before you commit. Arranging financing after an accepted offer, with a firm closing date already running, leaves far less room to fix a problem.
