When a Quebec investor analyzes a duplex or triplex, energy goes into price, interest rate and down payment — three visible variables, but largely taken (the market sets them). What's almost always underestimated is the third leg of return: tenant placement quality. Over a 10-year horizon, it's what turns a "decent" cap rate into actual IRR — or destroys it.
This article quantifies the impact. The numbers come directly from the plex investment analysis tool using a representative Montreal triplex. You leave with a grid to integrate placement quality into every pre-purchase analysis.
Why plex IRR is fragile
On a Montreal, Laval or Longueuil plex priced $600,000 – $1,200,000 with a 5.5% mortgage, operating cashflow typically runs $2,000 to $6,000/yr pre-tax — thin margin. Three variables that placement directly controls flip this result:
- 1Vacancy between tenants. Each empty month at $1,800 = -$1,800 of income + ~$200 of fixed costs that don't go away.
- 2Bad debt. A tenant who doesn't pay during the TAL process (5-8 month average in Quebec in 2026) costs $9,000 to $14,000 per file — before legal fees.
- 3Turnover. Each rotation = vacancy + make-ready costs + remarketing + lost compounded TAL increase.
The demonstration: same triplex, three placement qualities
Take a representative Montreal triplex:
- Purchase price $850,000
- 3 units × $1,700/mo = $61,200 gross annual rents
- 20% down ($170,000), $680,000 loan at 5.5% amortized 25 yrs
- Municipal + school tax ~$7,500/yr, insurance $3,000, maintenance 1.5% of value
- Personal solo ownership, 47% marginal rate
We model three placement scenarios over 10 years, keeping ALL other parameters identical. Only placement quality varies:
| Scenario | Avg vacancy | Bad debt | Turnover | 10-yr after-tax IRR |
|---|---|---|---|---|
| A — Passive placement (Kijiji, minimal screening) | 8% | 3% of rents | 1 unit/yr | 3.8% |
| B — Average placement (basic solo screening) | 5% | 1.5% | 1 unit / 2 yrs | 5.4% |
| C — Rigorous placement (OACIQ broker, full verification) | 2.5% | 0.4% | 1 unit / 4 yrs | 7.1% |
Year-1 breakdown — where the money goes
To understand where the gap comes from, here's the year-1 breakdown between passive placement (A) and rigorous placement (C):
| Line item | Scenario A — passive | Scenario C — rigorous | Gap |
|---|---|---|---|
| Gross rents collected | $56,304 (8% vacancy) | $59,670 (2.5% vacancy) | +$3,366 |
| Loss on bad debt | -$1,836 | -$245 | +$1,591 |
| Make-ready costs (rotation) | -$2,200 | -$550 (pro-rated 1/4) | +$1,650 |
| Remarketing fees | -$650 | -$160 | +$490 |
| TAL increase secured at renewal | $0 (rotation = reset) | +2.3% × in-place rent | +$1,370 |
| Annual difference net of tax | — | — | +$8,467 |
Compounded over 10 years at a moderate reinvestment rate (5%), this annual gap becomes ~$110,000 pre-tax, ~$63,000 after tax at 47% marginal — plus a higher resale value because exit rents sit closer to market (less gap to fix).
The 4 mechanisms that convert good placement into IRR
- 1Vacancy reduction — each empty day costs ~$60/unit at $1,800/mo. Rigorous placement compresses the between-tenant window from 30-45 days to 7-15 days via pre-qualification and a pre-vetted candidate pipeline.
- 2Bad debt elimination — verifying payment capacity (rent-to-income ratio max 30%), Equifax credit history, and previous landlord references drops default rates from ~3% to ~0.4%.
- 3Longer average tenure — a well-matched tenant stays 3-5 years on average, vs 12-18 months for a poor match. Fewer rotations = less make-ready, less remarketing, more compounded TAL increases.
- 4Preserved TAL increase right — a tenant who stays 5 years absorbs 5 compounded index increases (~12-14% cumulative). A tenant who leaves every year allows a market reset — theoretically positive, but in practice cancelled by transition costs and uncertainty.
Why "solo via Kijiji" placement destroys IRR
The investor who places tenants himself via Kijiji or Marketplace to save ~1 month of rent thinks he gained $1,800. In reality, over 10 years the cumulative gap between passive and rigorous placement often exceeds $60,000 after tax on a single triplex. The math is asymmetric: saving a visible cost once (placement) costs an invisible revenue every month (vacancy, default, turnover).
Add the risk of involuntary discrimination in solo tenant selection, which exposes to a CDPDJ complaint (up to $15,000 in moral damages per recent decisions). The objective criteria applied by an OACIQ broker neutralize this risk.
How to integrate placement quality into pre-purchase analysis
The plex investment analysis tool lets you model the three variables placement controls explicitly. Before submitting an offer, run three scenarios:
- 1Realistic-passive scenario — vacancy 5-8%, bad debt 2-3%, turnover 1 unit/yr. This is the default if you plan no placement strategy.
- 2Planned-rigorous scenario — vacancy 2-3%, bad debt <0.5%, turnover 1 unit / 3-4 yrs. This is reachable with OACIQ broker placement and full verification.
- 3Stress scenario — vacancy 10%, bad debt 5%, turnover 2 units/yr. This is the gap between BUY and AVOID for many borderline plexes.
If the IRR gap between scenarios 1 and 2 exceeds 1.5 points, your placement strategy is not an operational detail — it's the #1 lever of your business plan. Document it before signing the promise to purchase, not after taking possession.
Loi 31 and placement quality durability
Since February 2024, Loi 31 has tightened the framework around lease assignment, eviction-for-subdivision and senior-tenant protection. For investors, two direct consequences on IRR:
- The cost of a placement mistake is higher: removing a bad tenant takes longer and costs more. Initial selection must therefore be more rigorous.
- Lease assignment is harder to refuse without serious cause. A well-matched tenant stays — a poorly-matched one assigns to a third party you didn't screen.
Practical takeaway: under Loi 31, the premium on rigorous placement has gone up. The IRR gap between scenario A and C computed above is likely understated for post-2024 purchases.
The calculation to run before signing
Before submitting a promise to purchase on a plex in Montreal, Laval or Longueuil, the question is not "is the price right" — it's "can I protect the 10-yr IRR". Price is negotiated once; placement quality is played 30-50 times over the holding period.
Run the three scenarios in the tool. If the verdict stays BUY only in the rigorous scenario, your business plan depends entirely on placement. Lock the solution before closing — not a month after.
