Quick answer
What this means in practice
Home equity is the property value minus debts secured against it. Accessing that equity creates new secured debt; it does not turn the equity into free cash.
Key takeaways
- FCAC says a HELOC may allow borrowing up to 65% of the home’s value, subject to existing secured debt, equity, qualification, appraisal, and lender policy.
- Most HELOCs have variable rates, so the payment or interest cost can rise.
- Interest-only payments do not reduce the HELOC balance.
- Debt consolidation should show both monthly cash flow and total repayment cost.
A HELOC, refinance, and second mortgage solve different problems. Compare the amount needed, repayment plan, variable-rate exposure, fees, existing mortgage penalty, and total cost before choosing one.
How available equity is reviewed
The lender starts with an acceptable property value, then subtracts the mortgage and any other secured debt. FCAC states that a HELOC may allow borrowing up to 65% of the home’s value. A standalone HELOC generally requires more than 35% equity, while a HELOC combined with a mortgage generally requires at least 20% equity.
Those are product parameters, not guaranteed limits. Income, credit, appraisal, property, existing registrations, and lender policy can reduce the available amount.
HELOC, refinance, or second mortgage
A HELOC is revolving secured credit: borrow, repay, and reuse up to the approved limit. A refinance replaces or changes the existing mortgage and may suit a defined lump sum or debt restructure. A second mortgage sits behind the first mortgage and can preserve the first contract, but it may carry materially higher total cost.
Compare written options using the same amount and expected repayment period. Include the existing mortgage penalty, legal work, appraisal, lender or broker fees, discharge costs, and the effect on amortization.
The repayment risk
Most HELOCs use a variable rate linked to the lender’s prime rate. The lender may require interest-only or principal-and-interest payments. If only interest is paid, the balance does not decline.
Set a principal repayment amount and test the budget at a higher rate. Because the home secures the debt, missed payments can put the property at risk and the balance must normally be repaid when the home is sold.
Debt consolidation needs two answers
First, calculate the monthly cash-flow change. Second, calculate total repayment cost over the period the debt will actually remain outstanding. Extending short-term debt across a long mortgage amortization can lower the payment while increasing total interest.
The plan should also address how paid credit lines will be managed. Consolidating balances without changing the cause of recurring debt can leave the homeowner with less equity and new unsecured balances.
Costs to request in writing
- Current mortgage payout and penalty
- HELOC or mortgage interest rate and how it may change
- Appraisal, legal, registration, administration, and discharge fees
- Required minimum payment and repayment options
- Whether the charge affects a future switch or refinance
- Total projected cost for the intended holding period
When to slow down
Pause if the borrowing funds ongoing discretionary spending, the repayment plan depends on property appreciation, the budget only works at today’s variable rate, or the mortgage will be extended without comparing total interest. The right product should solve a defined need with a realistic way to repay it.
