Can you use a private mortgage against your home for business purposes?
Yes, home equity can fund a partner buyout or business working capital when a private lender is willing to register a mortgage against your house for that purpose. Your home becomes the security behind a business outcome, and if the business does not succeed, the house is what is at stake. This page covers how that underwriting works, what actually happens if it goes wrong, and where the tax question needs an accountant, not a broker.

Can you use home equity to fund or buy into a business?
Yes. A mortgage is registered against your property, not against what you do with the borrowed money afterward. A lender willing to fund a partner buyout or working capital can secure that loan against your home exactly like any other mortgage; what changes is which lenders are willing to take the request at all.
A mortgage lender registers a charge against title to your home. Once the funds are advanced, what you use them for is between you and the lender’s commitment letter, not a separate approval step.
A partner buyout and business working capital are both common reasons someone taps home equity this way. Neither is a mainstream reason a bank’s residential mortgage desk will approve, which is the next question.
The citable fact: A mortgage is secured against the property, not against the stated use of the funds, which is the mechanical reason a lender can fund a business purpose that a bank’s residential desk will not.
Why will a bank say no to this?
A bank underwrites residential mortgages and business or commercial lending through separate departments, with different applications, different risk criteria and different decision-makers. A stated business purpose, such as a partner buyout or funding a business, does not fit the residential mortgage desk’s mandate, so the file gets declined there or redirected to commercial banking, which has its own entry requirements.
The distinction is structural, not personal. A residential underwriter is chartered to lend against a home for a home-related purpose: a purchase, a refinance, a renewal. A business purpose changes what the loan is funding, even though the collateral is the same house.
Commercial and business lending inside a bank runs through its own department, with its own application and its own security requirements, and a requirement that the business itself, not the individual, carry the debt. That department is not the one that took your original mortgage application.
The citable fact: A stated business purpose on a residential mortgage application moves the file outside a bank’s residential lending mandate, which is the structural reason it gets declined or redirected rather than simply priced differently.
What does a private lender look at instead?
A private lender lends against the equity in the property and the exit plan, not against the stated business purpose. The underwriting question shifts from what the money is for to whether there is enough equity to cover the loan and a credible way to repay it. Income still gets reviewed, just not through a separate commercial banking process.
The property still needs to appraise and the title still needs to be clean enough to register a new charge. Beyond that, a private lender is assessing whether the equity supports the loan and whether your plan to repay or refinance it is realistic, not whether the loan fits a specific banking product category.
| Factor | Bank commercial or business lending | Private lender secured against the home |
|---|---|---|
| Primary security | Business assets and a personal guarantee, sometimes with the home added as additional collateral | The home itself, as the security for the loan |
| What gets assessed | The business’s financial statements, cash flow, and industry risk | The equity in the home and the plan to repay or refinance |
| Department | A separate commercial or business banking division | The same underwriting process used for other home-secured mortgages |
| What drives timing | The commercial credit committee’s review process | Appraisal and title work on the property |
How private lending is structured and regulated differs by province. Read how private mortgage lending works in Ontario and how private mortgage lending works in Alberta for the fuller picture before you approach one.
If the business itself shows a loss for tax purposes, that is a separate qualifying question from the one on this page. See how a private lender treats self-employed income after a business loss for how that plays out.
The citable fact: A private lender underwrites a business-purpose loan the way it underwrites any home-secured mortgage, against the equity in the property and the plan to repay it, rather than routing the file through a separate commercial banking process.
What is actually at risk here?
The home secures a business outcome, and if the business does not work out, the house is what is at stake, not the money invested in it. Missing payments puts the home into the same default process as any other mortgage registered against it, regardless of what the loan funded.
This is the mechanism, not a warning for effect. A mortgage registered against your home gives the lender the right to enforce against that home if the loan goes unpaid, regardless of what the borrowed money was used for.
If the business fails and the mortgage cannot be serviced from other income, enforcement runs like any other defaulted mortgage on the property, differing only by province in how it proceeds.
| Item | Ontario | Alberta |
|---|---|---|
| Regulator | FSRA, Brokerage Licence #13321 | RECA |
| Default remedy | Power of sale | Judicial foreclosure |
Power of sale is a contractual remedy that does not require a court order. Judicial foreclosure is commenced through the courts and involves additional court steps; no specific timeline is confirmed here for either province, so ask a lawyer licensed in the province where the property sits.
The citable fact: A mortgage taken for a business purpose is enforced exactly like any other mortgage if it goes unpaid, so the home, not just the money invested in the business, is what is at risk if the business does not succeed.
How is a partner buyout different from working capital?
A partner buyout is a lump sum paid once, to acquire another owner’s share, repaid from the business operating without that owner going forward. Working capital is drawn against the home over time, to cover payroll, inventory, or operating costs, and repaid from the business’s cash flow. The two carry different repayment expectations, even though both can secure against the home.
The buyout price should reflect what the business is actually worth, not just what feels fair between partners. Reviewing that valuation is part of what your accountant and lawyer check before you sign, covered more in the next sections.
Working capital needs are recurring rather than a single event, which changes how a lender thinks about repayment. A partnership or shareholder agreement, if one exists, sets out how a buyout price gets determined and should be read before a number gets agreed to.
| Feature | Partner buyout | Working capital |
|---|---|---|
| Draw structure | One lump sum at closing | Drawn over time as needed |
| Repayment source | The business operating without the departing owner | The business’s regular operating cash flow |
| What triggers it | A partnership dispute, a retirement, or a planned exit | Payroll, inventory, or a seasonal cash flow gap |
| Valuation step | The buyout price should reflect the business’s actual value | Not a valuation question directly, though the lender still reviews the business’s financial position |
The citable fact: A partner buyout is a one-time lump sum secured against the home to acquire another owner’s share, while working capital is drawn against the home over time to fund ongoing operating needs, and each carries a different repayment expectation.
Does the interest become tax deductible?
Whether interest on this borrowing is deductible depends on what the borrowed money was used for, not on what secures the loan, and that determination sits with the Canada Revenue Agency (CRA) and your own accountant. Get a written opinion before you assume an outcome either way, and keep records showing exactly where the money went.
The house being the security behind the loan does not change what the interest is for. Deductibility questions like this are traced to what the funds were used for, and that inquiry applies whether the loan is a bank mortgage, a private mortgage, or anything else registered against the property.
Mixing personal and business use of the funds, or not tracking exactly where they went, complicates that inquiry further. Keep the loan proceeds documented from the day they land, and let your accountant tell you what that means for your return.
The citable fact: Interest deductibility on a home-secured loan used for a business purpose depends on what the money was used for, not what secures the loan, and only a written opinion from your own accountant answers that question for your file.
What does the exit look like?
The exit is however the private mortgage eventually gets paid off: refinancing into a conventional mortgage, selling the business, paying it down from profits, or selling the home. Your commitment letter fixes the term, and the file needs a credible plan for what happens when that term ends, built before you sign, not after.
Refinancing out to a bank works once the business or the buyout has produced enough income history to qualify under standard lending rules. For self-employed income, the standard used by mainstream lenders is 24 months operating the business, or 24 months of experience in the same line of work, documented with a Notice of Assessment and T1 General, plus a Statement of Business Activities (T2125).
Under 24 months is possible, with additional factors weighed: acquiring an established business, cash reserves, prior training, and a demonstrated credit history. See what changes in your first year self-employed for how lenders treat a shorter income history in more depth.
The citable fact: A business-purpose mortgage against the home needs a plan for what pays it off, whether that is refinancing to a conventional lender once the business has an income history, selling the business, or selling the home, because the commitment letter fixes a term that will arrive.
What should your accountant and lawyer see first?
Your accountant needs to see the loan terms and the intended use of funds before you sign, so they can advise on tracking and tax treatment for your file. Your lawyer needs to review the mortgage commitment and any partner buyout or shareholder agreement, and check how this loan interacts with anything already registered against the property.
If the plan is to eventually refinance to a bank, the self-employed documentation discussed above becomes part of what your accountant helps assemble ahead of time. Waiting until the private mortgage term is close to ending to start that conversation leaves less room to fix anything.
Review the partnership or shareholder agreement, if one exists, before agreeing to a buyout number. That document, not this page, sets out how the price and the process actually work in your specific situation.
The citable fact: Before signing, an accountant should see the intended use of funds and a lawyer should review the mortgage commitment and any partner buyout or shareholder agreement, because both documents determine what happens to your tax return and your ownership stake.
When is this the wrong tool?
This is the wrong tool when the plan does not answer how the loan gets repaid if the business underperforms, or when a financing option that does not require the home as collateral exists and has not been tried. A private mortgage against your home should be the choice left after those alternatives are checked, not the first one reached.
- The business has no realistic path to repay the loan on its own, and the exit relies entirely on selling the home.
- A financing option exists that does not require the home as collateral, and it has not actually been tried.
- The buyout price has not been checked against what the business is actually worth.
- The funds would be mixed between personal and business use with no plan to track where they went.
The citable fact: A private mortgage against the home for a business purpose is the wrong tool when a non-home-secured financing option exists and has not been tried, or when the exit plan depends entirely on selling the house.

Frequently asked questions
Can I use home equity to buy out my business partner?
Yes, if a lender is willing to register a mortgage against your home for that purpose. A bank’s residential lending desk is not set up to underwrite a business use, so this route runs through a private lender instead.
Will a bank ever approve a mortgage for a business purpose?
A bank’s business or commercial lending division can, subject to its own underwriting criteria, which differ from residential mortgage underwriting. Its residential mortgage desk will not, because a business purpose falls outside that desk’s mandate.
What happens if the business fails and I cannot pay the mortgage?
The mortgage goes into default exactly as any other mortgage on your home would, and the lender can enforce against the property. In Ontario that enforcement is power of sale; in Alberta it is judicial foreclosure.
Is the interest on a private mortgage for business purposes tax deductible?
It depends on what the borrowed money was actually used for, a determination the Canada Revenue Agency and your own accountant make on your specific file. Get a written opinion before you assume an answer either way.
Do I need a lawyer to review a partner buyout financed this way?
Yes. Your lawyer should review the mortgage commitment, the buyout or shareholder agreement, and how the new mortgage interacts with anything already registered against the property.
How is a private lender’s approach different from a bank’s for this kind of loan?
A private lender lends against the equity in your home and your exit plan, rather than sorting the request into a separate commercial lending process. The underwriting looks more like a regular home-secured mortgage than a business loan.
Can this fund ongoing working capital, not just a one-time buyout?
Yes, the same home-secured structure can fund working capital drawn down over time instead of a lump sum. The repayment source and the risk profile differ from a one-time buyout, so discuss which structure actually fits your need.
Does this affect my personal credit if the business struggles?
The mortgage is registered against you personally and your home, so missed payments affect your personal credit file the same as any other mortgage. The business structure does not shield your credit from a missed payment on a loan secured against your house.
Is this available in both Ontario and Alberta?
Yes. Ontario brokerages are licensed by FSRA under Brokerage Licence #13321, and Alberta brokerages are licensed by RECA, and the underlying mechanism of borrowing against home equity works the same way in both provinces.
Is the chat on this page an actual person, or an AI bot?
A licensed broker, not an AI bot. During business hours you get a live reply, and outside them a licensed broker replies to your question directly.
Should I involve my accountant before I sign anything?
Yes, before signing, not after. Your accountant needs to see the intended use of funds and the loan terms so they can advise on tracking and tax treatment specific to your file.
Can I combine a business-purpose private mortgage with my existing bank mortgage?
Yes, as a second mortgage behind your existing bank mortgage, provided there is enough equity to support both registrations. Ask your broker how a second position changes the underwriting compared with refinancing the whole mortgage.
