What the Jump From 65% to 80% Equity Access Means for the Smith Manoeuvre™
On a $900,000 house in Vernon with $400,000 left on the mortgage, the difference between borrowing to 65% and borrowing to 80% is $135,000. That's what a combined mortgage and line of credit can now reach on many readvanceable products. For years most homeowners carried 65% around in their heads as the ceiling. Lenders now let the total go to 80% of the home's value, and in Okanagan prices even that 15-point gap is real money.
If you own a home with good equity, you've probably noticed your own number creeping up, whether it's a HELOC limit on your statement or a note from your bank. What you do with it matters more than how big it is. The extra room is valuable for one purpose above the rest: shifting your debt from the kind the taxman ignores to the kind he helps pay for. That's the engine of the Smith Manoeuvre™, and it's also why spending the same room on a truck or a kitchen leaves you worse off than you think.
How the 80% limit actually works on a Vernon home
The 80% figure covers the whole borrowing package. OSFI still caps the revolving part, the line of credit you can draw and repay at will, at 65% of the home's value. Anything above that must be an amortizing mortgage you pay down on a schedule. A readvanceable mortgage bundles the two under one registration.
Take the same Vernon home. At 80%, total borrowing can reach $720,000. Your $400,000 mortgage amortizes, and the line of credit can sit beside it at up to $320,000, which stays well under the 65% revolving cap of $585,000. Under the old 65% thinking, you'd have had $185,000 of room. Now you have $320,000.
The feature that matters most for planning is quieter. Each time a mortgage payment knocks down principal, the line of credit limit grows by the same amount. Your total stays inside 80%, but the mix keeps shifting from amortizing debt toward available credit. That automatic shift is what the Smith Manoeuvre runs on.
Before any of this is yours, you still have to qualify. Federal rules make you prove you could carry the payments at the higher of your contract rate plus 2% or 5.25%. Plenty of households with large equity find their income, not their house, sets the real limit.
Why the same borrowed dollar can be deductible or not
Under the Income Tax Act, interest is deductible when the borrowed money is used to earn income: a rental property, dividend-paying shares, a business. CRA looks at what the money bought. It doesn't care that your house secured the loan.
That one rule turns your line of credit into two very different things depending on the day. Here's illustrative arithmetic, with round numbers as an example only. Say you borrow $100,000 at 5% and pay interest only. That's $5,000 a year. Use it to buy a non-registered portfolio and, if your combined marginal tax rate were 40%, the deduction would hand back about $2,000 at tax time. Your real cost drops to around $3,000. Use the same $100,000 for a renovation or a vacation and you pay the full $5,000 out of after-tax income, with nothing producing a return to cover it.
The Smith Manoeuvre puts this rule on repeat. Every mortgage payment frees up a little room on the line of credit. You re-borrow that amount and invest it. The investment loan's interest is deductible, the refund goes back against the mortgage, and the cycle speeds up. Over time the non-deductible mortgage shrinks and the deductible investment loan takes its place. Total debt stays about the same. What changes is who effectively pays part of the interest.
The bigger combined limit gives this process more room to run. It also lets some households convert faster, for example by selling existing non-registered investments, paying down the mortgage with the proceeds and re-borrowing to buy back in. The tax rules around that kind of swap need careful handling with your accountant.
For landlords, the same rule powers Rental Cash Damming. You pay the rental property's expenses from the line of credit, which keeps that interest deductible, and send the actual rent cheques at your home mortgage. The rent kills off the non-deductible debt while the line of credit carries the deductible kind. More room means you can keep doing it longer before you run out of space.
There's one trap that catches people constantly. Once a line of credit mixes investment draws with personal spending, tracing which interest is deductible gets messy, and sometimes indefensible. A single account used for both purposes can cost you the deduction on the part you were entitled to.
Who should use the extra room and who should leave it alone
The room suits people with a long horizon, steady income that clears the stress test comfortably, a clear plan for income-producing investments, and the stomach to keep investing through a bad market while the loan stays the same size. It also suits landlords who can keep rental expenses and personal spending in separate accounts.
Leave it alone, or leave most of it untouched, if your household budget already feels tight, if a drop in your portfolio would push you to sell at the bottom, or if the honest reason you want the room is a purchase that won't earn anything. Untouched credit still has value as a buffer. A zero balance usually costs nothing to carry, and in a province where a roof or a job gap can run into five figures, that room is a backstop.
Three risks deserve plain language. A HELOC is a demand loan, so in a severe downturn the lender has the right to freeze or reduce your limit. It's almost always variable, so your payment rises the moment rates do. And readvanceable products in BC are usually registered with the Land Title and Survey Authority as collateral charges, which makes it easy to adjust amounts with your current lender and often costs legal fees to move to a new one at renewal. None of these rules out the strategy. They do mean you should never borrow to the edge of the limit just because the bank allows it.
Three moves to make before you draw a dollar
Give every dollar a written job. Before you draw, write down what it will buy and how that thing earns income. If you can't name the income, the dollar stays on the line.
Split the line into separate sub-accounts. Keep one for investment borrowing and one for rental expenses if you're a landlord, and never run personal spending through either. Most readvanceable products let you set up multiple segments under one registration, which keeps the paper trail clean for CRA.
Set your own ceiling below the bank's. Work out the payment on your planned balance at your current rate plus two percentage points. If that number would strain your month, borrow less. Treat whatever sits above your ceiling as your emergency room, and keep it at zero.
The bank sets the limit. The tax return will show what you used it for.
