The financing on a $2 million apartment building is usually better than the financing on a $700,000 rental condo. Longer amortizations, competitive rates, and underwriting that tests the building’s income first. This lesson explains why, and what it means for how reachable this asset class actually is.
The dividing line is five units. At five residential units, a property crosses out of the residential lending world and into CMHC’s multifamily framework — the same federal housing agency, running programs built specifically for apartment buildings. Everything changes at that line.
Underwriting tests the building’s debt coverage first. Residential lending asks: can this person’s income carry this debt? That’s the qualification math from Lesson 2: your salary can only stretch across so many mortgages. Multifamily lending asks a different question: can this building’s income carry this debt? The lender takes the NOI you learned to compute in Lesson 3, applies a coverage cushion, and sizes the loan the building can service. Your personal income matters far less; your building’s net operating income matters far more.
CMHC insurance makes the debt cheaper and longer. Because the loan carries federal mortgage insurance, lenders take less risk — and price accordingly: rates on insured multifamily debt are typically below comparable conventional lending, and amortizations run far longer than the residential world allows. Under CMHC’s MLI Select program, buildings that commit to affordability, energy efficiency, or accessibility criteria earn reduced insurance premiums and extended amortizations — the stronger the commitment, the better the terms. Longer amortization means lower payments per month, which means more of the net operating income survives as cash flow. Remember Lesson 7’s spread lever when you get there: cheaper debt is one of the largest drivers of the outcome.
What this means for reach. Work one illustrative case: a six-unit building in an Ontario secondary market at $1.2 million. At the conservative end of insured multifamily leverage, the equity requirement lands in the range of $180,000–$300,000 plus closing costs — with the building’s own income servicing the debt. That is not nothing. It is also not the “buildings are for rich people” number most people carry in their heads. The gap between a serious residential down payment and a first building is smaller than almost anyone assumes, and the financing on the far side is better.
Two cautions. Insured multifamily loans involve more process than a residential mortgage — CMHC reviews the property, the market, and the borrower, and it takes weeks, not days. And insurance premiums are a real cost, added to the loan; they buy the rate and amortization advantages, and the Financing Modeler sets each premium beside what it buys.
Homework: test the arithmetic on a real building in the Financing Modeler. It sets a 25-year conventional amortization beside the longer insured ones, with the monthly payment and annual cash flow of each.
Next lesson: the full costs — taxes, premiums, friction — and when buying a building is the wrong move.
