How to finance a suite or multiplex.

The part that stops most owners is not construction — it is not knowing how the money works. Here is the honest version.

Start with the reframe: almost nobody pays for a suite or a multiplex in cash. These projects are financed — and when they're structured well, the rent services the debt. The question isn't "do I have $300k?" — it's "does the project's income support the borrowing?"

The equity ladder

  • Home equity (HELOC or refinance) — the most common starting point. If you've owned for a while, your equity often covers a basement or garden suite outright.
  • Construction / improvement financing — lenders advance funds in draws as the build progresses. More paperwork, but it means you don't need all the capital up front.
  • Refinance on completion — the quiet superpower of these projects. Once built, your property is worth more and produces income. Refinancing against the once-built value frequently repays the construction borrowing.

Government-backed programs

CMHC-supported, insured financing can meaningfully improve terms — longer amortizations, better rates, lower down-payment requirements — especially for purpose-built rental. Larger rental projects (5+ units) can access dedicated programs with the most favourable terms. Eligibility is project-specific, which is why the report maps programs to your plan rather than a generic list.

Warning — the cancelled federal loan: the widely publicized $80,000 federal Secondary Suite Loan was cancelled in Budget 2025 and never launched. Anyone still advertising it is working from stale information. Build your plan on programs that actually exist.

What lenders actually look at

  • Your equity and income — the conventional stuff still matters.
  • The project's income — realistic rent, vacancy assumptions, operating costs. Lenders increasingly count projected rental income toward qualification.
  • Legality — an unpermitted suite's income often doesn't count. A legal one does.
  • A credible plan — real drawings, real budget, real timeline. This is where an accountable team pays for itself at the bank.
