Strategy stacks
Most Canadian mortgage strategies are stronger combined than standalone. Four stacks show up over and over on the files I work: a low-risk single-move stack, the most common landlord combination, an aggressive wealth-building stack, and a debt reset for high-consumer-debt files. Each is built from strategies on this site, and each fits a different audience.
For any specific file, the right stack depends on equity, income, risk tolerance, tax bracket, and time horizon. The ranges below are illustrative. A 30-minute conversation lets us run yours against the real numbers. Start with the Strategy Triage if you're not sure which stack applies.
The Simple Optimizer
Risk: LowOne move. No new debt. No new accounts. The lowest-risk play in Canadian mortgage strategy.
Who it fits. Almost every homeowner with a mortgage who isn't already on accelerated bi-weekly. No rental property required, no equity required, no investment portfolio required.
When it doesn't fit. Households where the slight cash-flow timing shift on the two months a year with three bi-weekly periods would create real budget pressure. Otherwise: there's no avoid case.
The sequence
- 1Accelerated Payment Frequency
Switch monthly to accelerated bi-weekly. One extra monthly payment per year, all to principal.
Combined impact
Three to five years off a typical Ontario mortgage. Tens of thousands in total interest saved. No rate change, no product change, no behaviour change, no new account. The cheapest mortgage strategy that exists.
The Landlord Stack
Risk: ModerateThe most common multi-strategy combination on this site. Built for households with one or two rentals and a real personal mortgage to chip away at.
Who it fits. Owner with a primary mortgage and at least one stable, positive-cash-flow rental property. Marginal tax rate 30%+ for the cash-damming deduction to be meaningful. Willing to keep three accounts cleanly separated (the discipline is the strategy).
When it doesn't fit. Households without rental property (strategies 1 and 3 don't apply). Landlords with negative-cash-flow rentals (the dam volume isn't large enough to compound). Files where mortgage renewal is more than 18 months out (the structural foundation is best set at the renewal window).
The sequence
- 1Readvanceable Mortgage Setup
Foundation product. The HELOC sub-account that grows as principal pays down is what makes cash damming possible. Set this up at the next mortgage renewal (penalty-free moment).
- 2Rental Cash Damming
Route rental income to the personal mortgage, pay rental expenses off the HELOC sub-account. Same dollars in and out, completely different tax outcome.
- 3Rental Amortization Extension
Stretch the rental amortization to free monthly cash flow. Aim that cash flow at the personal mortgage. Trade a non-deductible dollar for a deductible one.
- 4Accelerated Payment Frequency
Layered underneath. Same as the Simple Optimizer, but compounding with the redirected rental flows.
Combined impact
Pays off the personal mortgage 10 to 15 years earlier on a typical file. Cumulative deductible interest in the $40,000 to $60,000 range over the run. Cumulative tax savings of $15,000 to $25,000 reinvested back into the personal mortgage. The HELOC ends the cycle larger, but every dollar on it is deductible.
The Wealth Builder Stack
Risk: HighThe aggressive version. Builds an investment portfolio while accelerating mortgage paydown. Requires real risk tolerance and a 10 to 15 year horizon.
Who it fits. Homeowner with meaningful equity ($100K+), stable income, marginal tax rate 35%+, comfortable holding investment debt through a market downturn. 10+ year horizon. Investment experience or willingness to hold mainstream diversified assets through the ride.
When it doesn't fit. First-time investors. Anyone within 5 years of retirement. Anyone who would panic-sell in a 30% drawdown. The math says you keep the loan and the deduction; real households watching their portfolio drop don't always do that. If a 2008-style drawdown would force you out of position, this stack isn't right.
The sequence
- 1Readvanceable Mortgage Setup
Foundation. Without it, every borrowing event is a fresh HELOC application.
- 2Investment Leverage Strategy
Borrow against home equity, invest in income-producing non-registered assets, deduct the loan interest. The tax refund flows back at the personal mortgage.
- 3Velocity Banking
Optional layer on the HELOC portion for households that want forced-savings discipline. Honest framing: 80% of the benefit comes from accelerated bi-weekly alone. Add this only if the structure helps you save consistently.
- 4Accelerated Payment Frequency
Baseline. Always layered.
Combined impact
On a 15-year horizon, builds a non-registered investment portfolio of $200K to $500K depending on contribution rate and returns, while paying off the personal mortgage 3 to 6 years earlier than baseline. Tax-deductibility on the loan interest is the lever; the portfolio is the wealth.
The Debt Reset Stack
Risk: ModerateFor households carrying meaningful high-interest consumer debt alongside a mortgage. Resets the debt structure, then accelerates paydown on the new base.
Who it fits. Homeowner with $20,000+ in high-interest consumer debt (credit cards, lines of credit, car loans) and enough home equity to absorb the consolidation under 80% loan-to-value. Critically: a household ready to address the spending pattern that built the consumer debt in the first place.
When it doesn't fit. Households where the spending pattern that created the debt is still active. Consolidating the cards and then running them right back up is the most common failure mode of this stack, and it leaves the household worse off than before. If you can't close the credit accounts the same week as the refi funds, this stack isn't ready.
The sequence
- 1Cash-Out Refinance
Roll the high-interest consumer debt into the mortgage at a much lower blended rate. The math is straightforward; the discipline is everything.
- 2Accelerated Payment Frequency
Set the new mortgage to accelerated bi-weekly from day one. Treat the freed monthly cash flow (from the consolidation) as a head start on paydown, not a raise.
- 3Velocity Banking (optional)
Optional layer on remaining HELOC capacity if the household wants forced-savings discipline. Skip this if the discipline is already in place.
Combined impact
Monthly cash flow improvement of $500 to $2,000 in year one (depending on consumer-debt total and rates). Total interest saved over 5 years: $15,000 to $40,000 on a typical file. Long-run impact depends entirely on whether the consumer debt stays gone.
Want to run your file against these stacks?
About 30 minutes. We'll work through your inputs, run the relevant calculators, and identify which stack (if any) fits your file. Sometimes the answer is “the Simple Optimizer for now, revisit when X changes.” That's a valid outcome.
