Home Equity & HELOC
Using Home Equity to Pay for Renovations
Using home equity for renovations lets you tap your home's value with a HELOC, cash-out refinance, or second mortgage. Compare costs, risks, and how to qualify.
Using home equity for renovations means borrowing against the portion of your home you already own and putting that money into upgrades. The most common route is a home equity line of credit (HELOC), but a cash-out refinance, a home equity loan, or a second mortgage can also work. The right pick depends on how much you need, how fast you can repay, and whether you want a fixed or variable payment.
How much of your equity you can actually borrow
Equity is your home's appraised value minus everything still owed on it. If your home appraises at a certain value and your mortgage balance sits below that, the difference is yours on paper. Lenders, however, rarely let you borrow all of it.
A common structure caps the revolving portion of a HELOC at 65% of your home's value, with total borrowing against the property typically limited to 80% combined loan-to-value (LTV). That 65% ceiling comes from OSFI's Guideline B-20, which sets underwriting expectations for federally regulated lenders. Individual lenders can be stricter. Confirm the current limits with your lender before you plan a budget around any number.
One more rule worth knowing: refinances that push your loan-to-value above 80% generally cannot be insured by CMHC, so a high-ratio cash-out refinance usually is not available.
Your main options at a glance
Here is how the main ways to pull equity out of your home compare.
| Option | Best for | Rate type | Watch-outs |
|---|---|---|---|
| HELOC | Phased projects with an unknown final cost | Usually variable, tied to prime | Payment moves with prime; minimum payment is often interest only |
| Cash-out refinance | Large projects, one fixed payment | Fixed or variable | Legal fees, appraisal, possible prepayment penalty |
| Home equity loan | A known cost with fixed repayment | Usually fixed | Second charge on title; lender approval needed |
| Second mortgage or private lending | Fast funding, weaker credit | Fixed, higher cost | Higher rates and fees; confirm every cost in writing |
If you want the flexibility to draw funds as trades finish, a HELOC is usually the most practical. If you would rather lock in one payment and know the total cost up front, compare it with a cash-out refinance, and see how the two stack up in our home equity loan versus HELOC comparison.
What borrowing against your equity costs
HELOC rates are typically variable and quoted relative to prime rate, which moves when the Bank of Canada changes its policy rate. A small change in prime shifts your payment on the entire balance, so budget for movement rather than assuming a fixed cost.
Refinancing and second mortgages carry their own costs: a home appraisal, legal or notary fees, title work, registration, and sometimes a discharge fee on the existing mortgage. If you break a fixed-rate mortgage early, you may owe an interest rate differential (IRD) penalty, which can be substantial. Ask your lender for a written payout statement before you commit to anything.
Also note that Canada generally does not allow a deduction for interest on money borrowed for a principal residence, unlike the U.S. mortgage interest deduction. Confirm your own situation with a tax professional.
Qualifying: stress test, ratios, and paperwork
Whether you refinance or open a HELOC, lenders apply the federal mortgage stress test. You must show you can carry the debt at the higher of your contract rate plus two percentage points, or the published qualifying-rate floor. Confirm the current floor with OSFI or your lender. For the mechanics, see our stress test guide.
Lenders also look at your gross debt service (GDS) and total debt service (TDS) ratios, which measure the share of income consumed by housing costs and by all debt payments combined. Adding a renovation loan raises your TDS, which can affect renewals, refinances, and future borrowing.
Expect to provide income verification such as pay stubs, T4s, or notices of assessment, proof of your mortgage balance, property tax bills, and consent for a credit check. The lender may also send an appraiser or use an automated valuation model to confirm your home's value.
Which renovations tend to pay off
No renovation comes with a guaranteed return. That said, buyers and appraisers often respond to kitchens, bathrooms, finished basements, energy upgrades such as insulation and windows, and strong curb appeal. Highly personal projects, like a pool or a specialized hobby space, may not recover their cost at resale.
Ask two questions: does this fix something broken or dated, and does it bring the home closer to what similar homes nearby already offer? Borrowing for work that protects the home's value, such as a roof or furnace, is easier to justify than financing a project strictly for your own enjoyment.
A practical step-by-step approach
- Get quotes from at least two contractors and build a realistic total, including permits and a contingency.
- Check your current mortgage balance and ask your lender how much equity you can access.
- Compare a HELOC, a refinance, and a second mortgage on total cost, not just the headline rate.
- If a refinance means breaking your mortgage, get any prepayment penalty confirmed in writing.
- Secure approval for the equity product before you sign a construction contract.
- Draw funds in stages tied to completed work, where the lender allows it.
- Pay down principal, not just interest, so the balance actually falls.

Risks to weigh before you sign
Your home is the collateral. If your income drops or rates rise and you cannot keep up, you are risking the property, not just your credit score. A renovation loan taken at the same time as a big project is a common trap: costs overrun, and the borrowing grows along with them.
Set a hard ceiling, keep an emergency fund outside the renovation budget, and avoid stretching to the maximum the lender offers. If your credit or income situation is complicated, a second mortgage or private lender may be the only path, but the cost is higher, so treat it as a short-term bridge and plan your exit.
Finally, remember that any new borrowing affects your TDS, which lenders review at renewal. Debt added today can make it harder to switch lenders or refinance later.
Frequently asked questions
Is it a good idea to use home equity to pay for renovations?
It can be, if the project is affordable and you have a clear repayment plan. You are using your home as collateral, so missed payments put the property at risk, not just your credit score. Borrowing for work that protects or improves the home's value is generally easier to justify than financing a highly personal project.
Can I use a HELOC to pay for renovations?
Yes. A home equity line of credit is one of the most flexible options because you draw funds as needed and typically pay interest only on what you use. Rates are usually variable and tied to prime, so your payment changes when the Bank of Canada moves its policy rate. Confirm the current terms with your lender.
How much can I borrow against my home for renovations?
Lenders commonly cap the revolving portion of a HELOC at 65% of your home's value and total borrowing against the property at around 80% combined loan-to-value, under OSFI Guideline B-20. Your own limit depends on your appraised value, mortgage balance, income, credit, and the lender's rules. Confirm the current figures with your lender.
Is interest on home equity used for renovations tax deductible in Canada?
Generally, no. Canada does not allow a deduction for interest on money borrowed for a principal residence, unlike the U.S. mortgage interest deduction. There can be exceptions in limited circumstances, so confirm your situation with the CRA or a qualified tax professional before assuming a deduction applies to your renovation borrowing.
