Use the Equity in Your Canadian Home, or Refinance the US Side?

If you already own on both sides of the border, or you own in Canada and want to buy in the United States, there are two ways to raise the money and they are not equivalent.

The two routes

Borrow against the Canadian property. A refinance or a home equity line of credit on your Canadian home, in Canadian dollars, then convert and buy.

Borrow against the U.S. property. A U.S. mortgage or cash-out refinance, in U.S. dollars, secured by the U.S. asset.

Most people default to the Canadian side, because it is familiar and their bank will do it. That is sometimes right and often not, and the deciding factors are rarely the ones people compare.

What actually decides it

Currency exposure. This is the big one and it is usually skipped. Borrow in Canadian dollars to buy a U.S. asset and you have a loan in one currency against an asset in another. If the Canadian dollar weakens, your debt is unchanged but the cost of servicing a U.S.-dollar life rises. Borrowing in U.S. dollars against a U.S. property matches the debt to the asset.

Which income services the debt. If the U.S. property produces rent, a U.S. loan can often be serviced by that rent, and on a DSCR basis it may qualify on the rent alone. A Canadian loan has to be serviced from Canadian income regardless of what the U.S. property earns.

Ease of qualification. Canadian borrowing against your own home is generally the simpler application. U.S. foreign national lending is very achievable but involves more documentation and a larger down payment or lower loan-to-value.

Rate. Worth comparing, and worth comparing last, because the currency and servicing questions usually move more money than the rate spread does.

Flexibility. A Canadian home equity line of credit can be drawn and repaid repeatedly, which suits a buyer who wants funds available for an opportunity. A U.S. mortgage is a fixed advance.

A tax dimension that belongs to your accountant

Interest deductibility, in both countries, depends on what the borrowed money is used for and how the property is held. The two routes can produce meaningfully different outcomes, and the answer is specific to your situation.

Ask a cross-border accountant before you choose the structure. This is one of the few decisions on a cross-border file where the tax treatment can outweigh everything else, and it is very difficult to restructure afterwards.

The pattern that usually holds

For a rental property, borrowing on the U.S. side tends to make more sense: the debt matches the asset, and the rent can service the loan.

For a personal-use property where you have strong Canadian equity and want the simplest path, the Canadian side is often easier, provided you understand the currency position you are taking.

For a buyer who wants both speed and matched currency, a common approach is a short-term Canadian draw to close quickly, then a U.S. refinance once the property is held. That works, but only if the U.S. refinance is confirmed as available before the Canadian money is drawn.

What to do first

Price both. Not the rates, the whole thing: the loan available on each side, the currency position, which income services it, and the tax treatment from your accountant. It is one conversation, and it routinely changes which side people borrow from. ---
