Rental income optimization · Longueuil and the South Shore

Opti Loyer recovers that gap — through audits, cash for raise and cash for keys — to lift your income and the value of your buildings at refinancing. And you only pay if it works.

The reality on the ground

Why South Shore rents lag below market.

Montreal's South Shore has changed its face. Longueuil, Brossard, Saint-Lambert, Boucherville, Saint-Hubert, Greenfield Park: these areas draw households that want to stay a few minutes from downtown while gaining space, parking and a bit of greenery. Rental demand has climbed, new developments rent at top dollar — and yet a large part of the existing stock has stayed frozen in time, with rents from another era.

The reason is almost always the same. On the South Shore, a good share of the duplexes, triplexes and small income properties belong to owner-occupants — the owner lives in one unit and rents out the others — or to small investors who own one or two buildings. These are people who know their tenants, who value stability, and who, year after year, simply never adjusted the rents. A good tenant who's paid on time for eight years — you don't touch that. It's human, it's understandable — but it creates a gap that widens quietly.

There's also a factor that's very specific to the South Shore: the arrival of the REM. This new light-rail network now connects Brossard and the bridge corridor to downtown Montreal in a matter of minutes, without a car and without traffic jams. For a tenant, getting closer to a station changes everything — and it pulls up the rental value of entire neighbourhoods. But the leases signed before this new landscape haven't budged. The gap between what sitting tenants pay and what a newcomer would pay today has widened, area by area.

The result: within the same block, a new unit rents at market price while the neighbour next door, on a long-standing lease, still pays the rate from several years ago. It's not rare to see a family-sized 4½ in Longueuil or Saint-Hubert rented hundreds of dollars below what a tenant would pay today for the unit across the street. Multiplied across the units of a building, the gap becomes enormous — and it earns nothing as long as it lies dormant.

That's exactly where the value hides. South Shore units are often larger, newer and better maintained than the stock in central Montreal; proximity to the bridges, the REM, services and major routes carries real rental value. The catch-up potential is very real — you just have to quantify it unit by unit, then go get it properly, without conflict and in compliance with the TAL.

The multiplier effect

On the South Shore too, every dollar of recovered rent multiplies into value.

An income property is valued from its net income, capitalized at the capitalization rate (cap rate). At a 5 % cap rate, each additional $1 of annual net income adds roughly $20 of value.

Example
Rent recovered+$150 / month / unit
Per year+$1,800
Value created$36,000
Example
Rent recovered+$300 / month / unit
Per year+$3,600
Value created$72,000
Example
Rent recovered+$500 / month / unit
Per year+$6,000
Value created$120,000

Tailored strategy

We choose the most profitable lever for each unit — cash for raise, cash for keys or management — and present you with a clear plan with numbers and a realistic timeline.

3

Negotiation and execution

We lead the approach and the negotiation on your behalf, with tact, and we draw up the voluntary agreement, documented and signed — without conflict before the TAL, and nothing without your consent.

FAQ

Frequently asked questions — rent optimization Longueuil and South Shore.

Do you offer rent optimization everywhere on the South Shore?

Yes. We work throughout the Longueuil agglomeration and across the South Shore — Longueuil, Brossard, Saint-Lambert, Boucherville, Saint-Hubert, Greenfield Park, as well as Saint-Bruno-de-Montarville, La Prairie and the surrounding Montérégie municipalities. Tell us your area and we'll confirm quickly.

Why are South Shore rents so often below market?

A large share of the South Shore's plex stock is owned by owner-occupants or small investors who keep their tenants for years and don't adjust rents year after year. Meanwhile, rental demand has climbed with the arrival of new households and improved transit to Montreal. The result: long-standing leases left well below what a comparable dwelling in the same neighbourhood is worth today.

What effect does the REM have on rental demand in Brossard and Longueuil?

The arrival of the REM, the light-rail network that now connects the South Shore to downtown Montreal, has made Brossard and the areas around the stations far more attractive to tenants who want to avoid the bridges and the car. This increased demand pulls the rental market upward, but many existing leases were never adjusted accordingly. The gap between those rents and what a new tenant would pay today has widened — and that's exactly the dormant value we quantify during the audit.

How much does an audit of my rents in Longueuil or Brossard cost?

Nothing. The initial audit is free and with no commitment, whether your building is in Longueuil, Brossard, Saint-Lambert, Boucherville or anywhere else on the South Shore. After that, you only pay if we get results: our compensation is tied to the value and income we earn you.

Is cash for keys legal on the South Shore?

Yes. Cash for keys is a voluntary move-out agreement: the tenant agrees to leave in exchange for compensation, freely and in writing. All of our work on the South Shore is done through signed, documented agreements, in compliance with Québec's rental board (the TAL). Nothing is signed without the tenant's consent, and nothing happens without yours.

My plex in Saint-Hubert has had frozen rents for years — is it too late?

No, quite the opposite. The longer a rent has stayed below market, the larger the gap to recover — and therefore the higher the optimization potential. A long-standing lease in Saint-Hubert or Greenfield Park is often the best candidate for a cash for raise or a cash for keys.

Is it worth it for just a duplex in Greenfield Park?

Yes. On an income property, every dollar of recovered rent capitalizes into value: at a 5% cap rate, a $100/month catch-up adds roughly $24,000 to the building's value. Even on a duplex in Greenfield Park or Saint-Lambert with a single below-market unit, the catch-up is often worth far more than you'd think.

Do I have to handle the discussion with my tenant myself?

No. We lead the approach and the negotiation on your behalf, with tact and respect. On the South Shore as elsewhere, you never have to manage the difficult conversation — we take care of it, and nothing is signed without your consent.

What's the difference between cash for raise and cash for keys on the South Shore?

Cash for raise keeps the tenant in place with a rent readjusted to market, mutually agreed in exchange for compensation; cash for keys frees up the unit in exchange for compensation, which lets you re-rent at market price. On the South Shore, where units are large and often occupied for a long time, we choose the lever based on your goal and the rent gap, building by building.

Are rents really below market in Saint-Lambert and Boucherville?

Often, yes. The proximity to Montreal via the bridges, the quality of life and steady rental demand pull the market up, but many leases in Saint-Lambert, Boucherville or Longueuil have stayed stuck at old amounts. The free audit compares each of your units to equivalent units in the same area to quantify the real gap — without ever assuming it in advance.
