The rent the sale couldn’t reset

a Trois-Rivières triplex under “le bail suit l’immeuble”

Quebec's rule that a lease survives the sale of the building meant a Trois-Rivières triplex's buyers inherited one tenancy that had never gone through a TAL-sanctioned rent increase in years. The unit's actual, legally collectible rent was well under the appraiser's market-rent opinion the buyers' own pro forma had assumed.

The client

Buyers purchasing a $395,000 triplex in Trois-Rivières, Quebec, inheriting three sitting tenancies under Quebec's rule that a lease survives the sale of the building -- a new owner cannot simply reset rent to market on closing.

The problem

Quebec's principle that a lease follows the building — le bail suit l'immeuble — means a change of ownership does not reset what a sitting tenant legally owes. Unit 3's tenant had lived there for years under a lease whose rent had never once been taken through a formal increase application at the Tribunal administratif du logement, so its rent had simply never moved while comparable units around it did.

Two numbers for the same unit

  • The buyers' own pro forma: $1,300/mo, the appraiser's market-rent opinion for a comparable unit
  • The actual legal rent: $850/mo, what the sitting tenant is legally obligated to pay under their existing lease
  • A future TAL-sanctioned increase is available to the new owner eventually -- it is not automatic, and it is not something a lender can credit at closing

A lender qualifying this file on the appraiser's optimistic figure would be crediting rent the buyers could not actually collect on day one. The gap wasn't a red flag on the file's soundness -- it was a documentation question about which number was real.

№ 03

The numbers

Running the offset against the actual legal rent instead of the assumed market figure showed the buyers a real, if modest, gap between what they had budgeted for and what the building would actually pay them at closing.

Qualifying on the rent actually owedAmount
Qualifying payment at 6.95%, 30 years$2,071/mo
Property tax and heat$470/mo
Rent recognized -- buyers' pro forma ($1,350 + $1,300 + $1,300), 50% offset$1,975/mo
Rent recognized -- actual legal rent ($1,350 + $1,300 + $850), 50% offset$1,750/mo
Total debt serviceBuyers' assumed pro formaActual legal rent
Housing cost after rental offset$566$791
Car loan$250$250
Total debt service11.8%15.1%

Neither number was close to a decline — this purchase was comfortable on the mortgage either way. What the correction actually protected was the buyers' own cash-flow expectations going into ownership, not the file's approval.

№ 04

The solution

A courtier hypothécaire licensed under Quebec's Act respecting the distribution of financial products and services treated the sitting lease, not the appraisal, as the controlling document for unit 3's rent.

First, pulled unit 3's actual lease and its full rent history. Confirmed directly that no TAL-sanctioned increase had ever been filed against it, rather than assuming the appraiser's comparable-unit figure was already being collected.

Second, priced the purchase and the mortgage's rental offset against the real $850 figure. The only rent a lender could actually rely on at closing, not the appraiser's opinion of what a comparable, unencumbered unit could fetch.

Third, flagged a future TAL rent-increase application as its own separate step. A path the new owners could pursue after closing, on the TAL's own process and timeline — not a closing-day assumption baked into the file.

№ 05

The outcome

The purchase funded conventionally at 4.95%, qualified on unit 3's actual legal rent at 15.1% total debt service, with Quebec's welcome tax on the purchase coming to $4,036.

This is an uninsured, non-owner-occupied purchase, so CMHC's ratio maximums don't apply here; both total-debt-service figures are informational, and neither was ever close to the file's actual approval threshold.

What to take from this file

  • 01A Quebec lease survives the sale of the building. Le bail suit l'immeuble means a new owner inherits the tenancy exactly as it stands, rent included — a sale is not a rent-reset event.
  • 02An appraiser's market-rent opinion is not the same as what a sitting tenant legally owes. Only the lease, checked against its own increase history, answers that question.
  • 03A rent that never moved for years is a signal worth chasing before closing, not after. Confirm whether any TAL-sanctioned increase was ever filed against a long-static lease.
  • 04A future increase is a separate project, not a closing-day number. Quebec's TAL process for raising rent has its own notice and timeline; it cannot be assumed into today's qualification.
  • 05Protecting the buyer's cash-flow expectations matters even when the mortgage clears comfortably either way. This file was never in doubt on approval — getting the real number right was still the job.

Sources

Every regulatory figure in this file traces to one of these primary sources. Client details and anything that varies by lender are illustrative, as flagged below.

Illustrative in this file — lender-specific, not rules:

  • 4.95% contract rate — rates move daily; not a quote.
  • the 50% rental-income offset — each lender publishes its own offset percentage against rental income; there is no single published rate.
  • the total debt service figures — this is an uninsured, non-owner-occupied purchase, so there is no CMHC ratio ceiling -- the numbers are informational.
