ImmoMulti — direct buyer of income properties on the North Shore — sees a reality many owners overlook: your plex can be worth far more for its land than for its building. When zoning permits many more units, or when the lot sits near a structuring transit station, it is no longer the current triplex being bought — it is the right to build something denser. In that scenario, the classic income-based economic valuation (the cap rate) often understates the true market value. Written from the owner-seller's point of view, this article explains how to recognize that potential, what drives land value up, and why targeting the right buyer — the developer — can maximize your sale price.
Land or building: two values that don't overlap
A plex's value splits in two: the building value (based on current rental income) and the land value (based on what zoning permits building there). When the ground's redevelopment potential exceeds the value of the rents, the land becomes the dominant asset — and a buyer pays for the future project, not the existing triplex.
Every plex rests on two stacked assets: the building and the land. Most income-property transactions on the North Shore are negotiated on building value — that is, capitalized rental income. But in certain cases the ground itself is worth more than the structure on it. Appraisers call this the "highest and best use": the legally permitted, physically possible and most financially profitable use one could make of a piece of land.
Take a typical example: an old single-storey duplex on a large lot, in a sector where zoning now allows a multi-storey building. The duplex may generate modest rents, but the land could hold ten, fifteen or twenty units. To a developer, the value does not come from the duplex — it comes from the construction potential. The existing building becomes almost incidental, even a cost to demolish.
Recognizing this distinction is the first step for an owner-seller. Selling such a plex purely on its rental income risks leaving money on the table.

How do you recognize that a plex has redevelopment potential?
Main signals: municipal zoning allowing more floors or higher density than what exists; a large land area; a corner lot; a location within a densification area or a TOD area near structuring transit; an older building of low relative value on sought-after land. Your municipality's zoning by-law is the reference document to consult.
Several clues reveal redevelopment potential in a plex. Here are the most telling:
- Zoning more generous than the current use: the municipal zoning by-law sets the permitted uses, number of floors, density and setbacks on each lot. If your two-storey plex sits in a zone that now allows four or six, the gap is monetizable potential.
- A large land area: the bigger the lot, the more a dense project becomes possible and profitable per buildable square foot.
- A corner lot: two frontages, better visibility and more layout flexibility — assets sought after for a larger project.
- Proximity to structuring transit: train, metro, REM or bus rapid transit. These sectors are often designated "TOD areas" and targeted by densification policies.
- A building of low relative value: an older, lightly renovated property whose economic value stays modest relative to what the land could support.
The concrete starting point: consult your municipality's zoning by-law, which specifies the permitted density and height on your lot. That is where the potential hides — or doesn't.

What drives up the value of redevelopment land?
Three levers dominate: the density permitted by zoning (more floors or units = more value per square foot), the area and configuration of the lot (large lot, corner), and location (in-demand sector, proximity to transit and services). Depending on permitted density, land values per square foot can vary considerably from one use to another.
The value of redevelopment land is not fixed: it depends directly on what can be built there. Here are the main factors that drive it up.
Density permitted by zoning
This is factor number one. Forecasting a density — for example the number of dwellings per hectare — is essential to developers and municipalities alike in assessing a project's profitability. Land allowing high density is worth more, because it spreads the land cost over a greater number of saleable or rentable units. Conversely, restrictive zoning caps the value.
Area and configuration
A large area and regular geometry make an ambitious project easier. A corner lot, with its two frontages, opens layout possibilities a landlocked lot does not. Assembling several adjacent lots can also multiply the potential — a developer will sometimes pay a premium for the missing piece of their puzzle.
Location and services
Pressure on urban perimeters intensifies competition for strategic land: proximity to infrastructure, densification potential and compatibility with local planning directly influence value. On the North Shore as elsewhere, well-located, well-zoned land stands out clearly.
| Factor | Effect on land value | For the seller |
|---|---|---|
| Permitted density (zoning) | More floors / units = higher value | Check the zoning by-law |
| Land area | Large lot = more profitable project | Gauge the buildable potential |
| Corner lot | Two frontages, more flexibility | An asset to highlight |
| Transit proximity (TOD) | Density encouraged, strong demand | Locate the nearest station |
| Existing building value | Low = land dominates value | Don't sell on rents alone |

The TOD factor: proximity to structuring transit
A TOD (Transit-Oriented Development) area is a medium-to-high-density sector structured around a high-capacity transit station. In Greater Montréal, the CMM delimits these areas within a 0.5 or 1.0 km radius of a station and sets density thresholds that can reach 80 dwellings per hectare. Land eligible for high density near transit is highly sought after by developers.
Transit-Oriented Development (TOD) refers to a medium-to-high-density real estate development structured around a high-capacity public transit station — commuter rail, metro, REM. In the metropolitan region, the Communauté métropolitaine de Montréal (CMM) delimits these areas within a 0.5 or 1.0 km radius depending on the infrastructure type, and sets minimum density thresholds that vary by context — around 40 dwellings per hectare for certain residential redevelopment projects, up to 80 dwellings per hectare in the best-served sectors.
The CMM's metropolitan land-use and development plan (PMAD) aims to steer at least 60% of new households toward TOD-type neighbourhoods located at access points of the structuring transit network. In practice, this means municipalities encourage — and sometimes require — greater density around these stations. If your plex on the North Shore sits within such a sector, the densification potential can strongly support your land value.
Check whether your plex is in a TOD area
- Identify the nearest structuring transit station (train, metro, REM, BRT)
- Measure the distance: within a 0.5 to 1 km radius, your land could be targeted
- Consult your MRC's land-use plan and the municipal zoning by-law
- Note the density and height permitted on your specific lot

Why does the cap rate then understate your sale price?
The cap rate capitalizes the current building's net income. By construction, it ignores what could be built in its place. When value lies in the land's redevelopment potential, a developer's value comes from the future project, not present rents. The purely economic cap rate misses this land premium.
The capitalization rate (cap rate) — the TGA in Québec — is the central tool for the economic valuation of a multi-unit building. It relates net operating income to value: a building generating $40,000 in net income at a 5% market cap rate is worth roughly $800,000. It is an excellent method… as long as value comes from rental income.
But the cap rate has a major blind spot: it only "sees" the existing building. It completely ignores what a piece of land could accommodate. On a lot with strong redevelopment potential, sticking to the cap rate is like appraising a gold mine at the price of the shed sitting on top of it.
This is where other methods come in. For redevelopment land, chartered appraisers mainly use direct comparison (recent sales of similar land) and the residual land value method: start from the value of the finished project zoning permits, subtract construction costs and the developer's margin, and the balance is the land value. These approaches capture a value the cap rate alone leaves invisible.
The cap rate's blind spot in one line
Selling a plex with strong land potential purely on its cap rate is the price of yesterday's building, not tomorrow's land. When a developer steps in, it is the residual land value — often higher — that should guide the asking price.
"To establish a land's value, you must identify the site's highest and best use by examining location, demographics, regulation and planning controls."

Targeting the right buyer: why the developer pays the premium
The developer buys the right to build, not income. They value zoning, permitted density, area and location. They often pay above the existing building's economic value, because their model rests on the future project. For a plex with strong land potential, targeting this buyer — rather than a plain rental investor — can maximize the sale price.
Not all buyers are equal when it comes to selling a plex with land potential. Two profiles stand opposed:
- The rental investor buys income. They calculate the cap rate, the gross rent multiplier, the return. They will pay the existing building's economic value — rarely more.
- The developer buys the right to build. They look at zoning, permitted density, area, location. Their profit comes from the project they will erect, not current rents. So they can pay a premium the rental investor could never justify.
For the owner-seller, the lesson is clear: if your plex has genuine densification potential, presenting it as a mere rental asset deprives you of the buyer who would pay the most. Document the potential — zoning, density, transit proximity — and target the developers active in your sector.
Be careful, however, not to overestimate. Not all land is redevelopment land: potential depends on specific, verifiable facts (actual zoning, area, constraints). Before setting a price or launching any process, have the highest and best use confirmed by a chartered appraiser who is a member of the Ordre des évaluateurs agréés du Québec (OEAQ).
