Most Ontario investors aim for duplexes, triplexes, or fourplexes. But the biggest jump in long-term wealth and financing power comes when you cross into five units or more. This blog explains why 5-plex conversions make more financial sense — and why REIs should stop thinking of properties as “houses” and start thinking in square footage and income potential.
5+ Units Unlock Commercial Financing
Once your building hits five units, lenders treat it as a commercial income asset, not a residential one. Benefits include:
- DSCR-based approval
- Better amortization options
- Income-based lending decisions
- Higher refinancing potential
- Less reliance on personal income
This alone can change an investor’s entire growth trajectory.
Your Value Is Based on Income — Not Comps
Triplexes and fourplexes are capped by residential comparables. Your neighbour’s sale affects your value. A 5-plex is valued using the income approach (NOI ÷ cap rate). Meaning:
- Operate better → value increases
- Improve layouts → value increases
- Raise rents → value increases
You control the appreciation.
You Often Only Need ~2,500 Sq. Ft. to Hit 5 Units
Most older Ontario buildings have:
- Large basements
- Attics with full head height
- Oversized floorplates
- Space for small rear additions
REIs underestimate how much density is already achievable — often without planning applications — if zoning already allows it as-of-right.
Parking Requirements Are No Longer a Barrier
Many municipalities have reduced or removed minimum parking requirements for new units. This opens the door for 5-unit conversions even on smaller urban lots. More units = more resilience.
- Vacancies impact revenue less
- Repairs are absorbed more easily
- Overall NOI increases
Investors gain long-term stability. Your building functions like a true commercial asset.
Cashflow Becomes More Stable
More units = more resilience. Vacancies impact revenue less, repairs are absorbed more easily, and overall NOI increases. Investors gain long-term stability, and your building functions like a true commercial asset.
The ROI on Renovation Costs Is Dramatically Higher
You’re already paying for fire separations, electrical upgrades, mechanical improvements, new layouts, and permit drawings. The incremental cost of adding the 4th and 5th units is often small compared to the increased income and appraisal value.
