In the ever-evolving world of personal finance, Canadian property owners are always on the lookout for innovative strategies to maximize their wealth. One such strategy is called rental cash damming, a powerful yet underutilized financial technique that can help rental property owners optimize tax efficiency. It’s especially effective for those juggling personal and investment-related expenses.

What is Rental Cash Damming?

Essentially, rental cash damming is a method of restructuring debt to convert non-tax-deductible debt (such as the mortgage interest on your primary residence) into tax-deductible debt. Here’s how it works:Use your rental income to make a prepayment on your primary residence’s mortgage.

-Re-borrow funds from your HELOC (home equity line of credit) to pay your rental property’s mortgage.

-Your prepayment increases the credit limit on your HELOC.

-Repeat this every month until your primary home’s mortgage is paid off and you have a balance on your HELOC whose interest is all tax-deductible.

-Your investment is now 100% financed and the interest paid is all tax-deductible.

Seems almost counter-intuitive, doesn’t it? Basically, what you’re doing is just redirecting your cash flow in a way that accelerates mortgage repayment and reduces your tax burden. It’s almost a no-brainer. However, cash damming is not a strategy available to everyone. There are certain prerequisites. We’ll get to that.

How Cash Damming Can Slash Your Mortgage Timeline

One of the most compelling benefits of rental cash damming is the ability to pay off your primary home’s mortgage faster. How? 

-Reduce your mortgage on your primary residence by rapidly paying it down with the rental income from your investment property.

-Covert your non-tax-deductible personal debt to business debt that can be deducted from your gross income.

-Apply the interest charges from your line of credit as deductions against your income.

-Use your tax refunds to pay down the principal on your primary residence’s mortgage to pay it off even faster.

Why Only Two Financial Institutions in Quebec Offer This Service

Despite its advantages, only two financial institutions in Quebec currently offer rental cash damming: Manulife and National Bank. The reason? Most banks don’t structure their mortgage and LOC products in a way that allows the seamless cash-flow cycling required for cash damming.

Manulife’s Manulife One “all-in-one mortgage and banking account” and National Bank’s All-in-One HELOC are specifically designed to allow flexible mortgage repayment and borrowing, making them ideal for this strategy.

Final Thoughts: Is Rental Cash Damming Right for You?
