WHY ONTARIO REIs SHOULD BE TARGETING 5-UNIT BUILDINGS (NOT TRIPLEXES OR FOURPLEXES)

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

  • Overall NOI increases

Investors gain long-term stability.

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

  • Permit drawings

The incremental cost of adding the 4th and 5th units is often small compared to the increased income and appraisal value. How Rojas Empire Helps Investors Execute 5-Unit Strategies We support investors by:

  • Assessing realistic density potential

  • Evaluating zoning & as-of-right permissions
