Every strategy on this site — the Smith Manoeuvre, cash damming, the meltdown's borrowing leg — runs on the same engine: credit that reappears as principal is repaid. But that engine ships in three different chassis, and the choice decides how automatic the strategy is, how clean the accountant's paper trail stays, and which properties qualify at all. Brand loyalty is the wrong way to pick; here is the right one.
Manulife One and National Bank's All-in-One: mortgage, chequing and credit fused into a single sweep account. Income lands and instantly works against the debt; repaid principal is available the same day; sub-accounts carve out clean strategy space. The most automatic chassis, usually carrying an account fee and a prime-linked rate.
A conventional mortgage with a linked line of credit that re-advances as principal falls — the majors each build a version. Often the sharpest headline pricing on the amortizing side; the craft is in the details: whether the limit grows automatically or on request, and how many separate sub-lines the structure allows.
A standard mortgage plus a standalone HELOC, re-limited by application every year or two. The cheapest to open and the most friction to run — and strategies that depend on monthly discipline tend to die of friction.
The one with automatic readvance and a dedicated sub-account for the investment draws — those two features are the strategy. Brand comes second: an all-in-one with clean sub-accounts and a bank pairing with automatic limit growth can both run it well, and the per-file pricing usually settles the tie. What can't run it well is the manual route, where every re-borrow needs an application.
Per file, honestly modelled — never assumed. The fee buys automation and daily sweep efficiency; whether that beats a cheaper pairing depends on cash flow, balances and discipline. The Manulife One calculator runs that comparison with the fee included, fairly.
Yes: it's a refinance, with the usual penalty and legal costs — all priceable in advance. But the cheap moment to choose is at purchase or renewal, when switching costs little or nothing. That's why the purchase page calls the readvanceable decision the cheapest piece of foresight on this desk.
The rules are identical on every chassis — deductibility follows use. What differs is how easy the paper trail is to keep clean: dedicated sub-accounts make tracing near-automatic; a single mingled line makes it an annual archaeology project. Choose the chassis your accountant will thank you for.
Structural features described here are as published in each institution's own materials and confirmed per file before anything is recommended — features and eligibility change, and the desk re-verifies at the moment it matters. The comparison never runs on memory.
The strategy gets the attention; the chassis decides whether it actually runs. Ten minutes on the six questions above saves a refinance later.
