From Residential BRRRR to Your First Commercial Deal in Nova Scotia
If you've been buying single-family and small residential rentals — BRRRR-ing your way to a portfolio — there's a point where the next logical move is a bigger building. In Canada, that usually means crossing the line into commercial financing at five units. This guide is for the residential investor making that jump for the first time in Nova Scotia: what changes, what stays the same, and how to structure your first commercial deal.
General information from the Indi Mortgage Commercial Division team — not financial advice.
In short: the moment a building has 5+ units it's financed commercially, and the biggest change is that the lender qualifies the property's income (via debt-service coverage) rather than your personal income. Down payments run higher than residential, but for 5+ unit rental, CMHC MLI Select can unlock higher leverage and longer amortization than anything on the residential side.
Where residential ends and commercial begins
The dividing line in Canada is units, not dollars:
- 1–4 units — financed as residential. Lenders lean heavily on your income, credit, and the standard residential rules you already know.
- 5+ units — financed as commercial (even though it's still residential rental). Now the building's income leads, and a different set of lenders, programs, and rules apply.
That single step — from a fourplex to a five-plex — changes the whole financing conversation. It's the most important threshold a scaling investor needs to understand.
What actually changes
1. The property qualifies, not (just) you
Residential lending sizes the loan around your personal income and covenant. Commercial lending sizes it around the property's net operating income (NOI) through the debt-service coverage ratio (DSCR) — NOI divided by the mortgage payments, usually with a 1.20–1.25 minimum. Your covenant still matters, but the building has to carry itself. For a BRRRR investor, this is actually liberating: strong-performing buildings can support financing largely on their own merit.
2. Down payments run higher — unless you use CMHC
Conventional commercial financing commonly tops out around 65–75% loan-to-value, so plan on 25–35% down. But 5+ unit residential has a lever residential doesn't: CMHC MLI Select, where high-scoring rental projects can reach up to 95% loan-to-cost. The right program often matters more to your equity than the price you negotiate. → CMHC MLI Select explained
3. The paperwork shifts from you to the building
Instead of just pay stubs and a T4, expect to provide a rent roll, 2–3 years of operating statements, a lender-ordered appraisal, and your corporate/personal financials. You're underwriting a small business now — the building.
4. Rates are quoted, not posted
There's no "posted" commercial rate; each deal is priced to its risk. → How commercial mortgage rates work
What stays the same (your BRRRR edge)
The instincts that built your residential portfolio transfer directly:
- Forced appreciation — raising NOI by fixing below-market rents or cutting expenses increases the building's value and the loan it supports, exactly like a residential rehab, only more powerful because commercial value is driven by income.
- The refinance mindset — the "R" in BRRRR is really a takeout. On commercial deals you plan the takeout or CMHC-insured refinance from day one.
- Buy right — a deal that doesn't pencil is still a deal that doesn't pencil. The math just runs through DSCR and cap rate now.
Your first commercial deal — a short checklist
- Model it first. Run NOI, DSCR, LTV, and both conventional and CMHC scenarios before you write an offer. (Do this in two minutes below.)
- Pick the structure, not just the rate. Conventional vs. MLI Select frequently moves your economics more than shopping lenders does.
- Package it like a business. Rent roll, operating history, your experience, and a clear plan.
- Line up the exit. Know your refinance/takeout before you buy.
- Use a commercial broker. The right lender for a Halifax five-plex is rarely the right one for a Dartmouth mixed-use building — a broker shops the whole market and structures the file to qualify.
