When does it make sense to refinance my mortgage?

Refinancing makes sense when: (1) current rates are meaningfully lower than your rate and the penalty is recouped within your remaining term; (2) you need to access equity for a large expense (renovation, investment, debt consolidation); (3) your financial situation changed and you need a longer amortization to lower payments; or (4) your relationship status changed. Always calculate the break-even period: penalty ÷ monthly savings = months to recoup. If you'll stay in the home longer than the break-even, refinancing makes financial sense.

What is a HELOC and how does it work?

A Home Equity Line of Credit (HELOC) is a revolving credit line secured against your home's equity. You can borrow up to 65% of your home's appraised value (minus your outstanding mortgage, subject to a combined maximum of 80% LTV). Interest is charged only on amounts drawn, not the full limit. Rate is typically prime + 0.5–1%. HELOCs are interest-only payments (you can make principal payments any time). They're fully open — no penalties for paying down or prepaying.

How much equity can I access through a refinance or HELOC?

Maximum borrowing is generally 80% of your home's appraised value, minus any outstanding mortgage balance. On a $900,000 home with a $500,000 mortgage: 80% × $900,000 = $720,000 − $500,000 balance = $220,000 accessible. A HELOC alone is capped at 65% LTV ($585,000 − $500,000 = $85,000 in this example). A cash-out refinance can access up to the 80% combined maximum.

What is a readvanceable mortgage?

A readvanceable mortgage combines a conventional amortizing mortgage with a HELOC in a single product. As you make principal payments on the mortgage, that paid-down amount becomes available as HELOC credit — the combined credit never goes below the original mortgage amount. This is the product used for the Smith Manoeuvre. Examples: RBC Homeline Plan, BMO Homeowner ReadiLine, CIBC Home Power Plan, TD FlexLine.

What is the Smith Manoeuvre and is it worth it?

The Smith Manoeuvre converts non-deductible mortgage interest into tax-deductible investment loan interest. Using a readvanceable mortgage, as you pay down your mortgage, you reborrow the paid-down amount via HELOC and invest it in Canadian dividend stocks or ETFs. The interest on the borrowed investment amount is tax-deductible. Over a 20-year mortgage, this strategy can add $50,000–$200,000+ in after-tax wealth, depending on investment returns and your marginal rate. It is best suited to disciplined investors comfortable with leverage.

Shared equity (reverse)	Up to 55% (reverse)	N/A (equity share)	At sale or in 10 years	Varies

Refinancing

When to refinance:

Rate is 0.5%+ lower than your current rate and penalty is recoupable
Need lump-sum cash (renovation, debt consolidation, investment down payment)
Need to extend amortization to lower payments
Removing a person from title (divorce, separation)

Cash-out refinance: Replace your existing mortgage with a larger one, receiving the difference as cash. Max 80% LTV.

Break-even calculation:

If penalty = $12,000 and monthly savings = $400, break-even is 30 months
If you stay in the home for more than 30 months past refinancing, you come out ahead
