The rent the lease hadn’t caught up to

an LTB-approved increase on a Windsor duplex

A Windsor duplex's signed lease still showed last year's rent on one unit, even though the Landlord and Tenant Board had already approved an above-guideline increase for a roof replacement. Qualifying on the LTB order's higher, already-effective rent -- not the stale lease figure -- brought the file's total debt service down.

Anonymized illustration. The borrowers, dollar figures, and rates in this file are an illustrative composite — no real client is identifiable, and any rate shown is illustrative, not a quote. The rules are real: every regulatory figure is cited to its source in the Sources section, and the math computes exactly as shown.

The client

Investors buying a $415,000 non-owner-occupied duplex in Windsor, Ontario, inheriting two continuing tenancies. Unit 2's rent was straightforward; unit 1's was not, because its signed lease and its actual legal rent had quietly stopped matching.

The problem

Ontario's Landlord and Tenant Board had approved unit 1's landlord to raise its rent for a roof-replacement capital expenditure -- an above-guideline increase, legally payable by the tenant from a specific effective date already passed. What hadn't happened yet was paperwork: the lease document itself, the piece of paper a lender's checklist usually asks for, still showed the old $1,650 figure, because nobody had gotten around to reprinting it.

Two documents, two different rents

  • The signed lease: $1,650/mo -- the number on the paper, unchanged since before the increase was approved
  • The LTB order: $1,810/mo -- the number the tenant is legally obligated to pay, effective before this closing
  • A lender reading only the lease would qualify the file on rent the tenant no longer legally owes at the lower figure

The gap was real but modest -- an above-guideline increase for one capital project, not a wholesale rent reset. That made it easy to miss and just as easy to fix, once someone actually pulled the LTB's own order rather than relying on the lease alone.

№ 03

The numbers

Once the rental offset was run against the LTB-approved rent instead of the stale lease figure, the file's own carrying-cost math shifted by exactly as much as the increase itself -- no more, no less.

Qualifying payment at 7.05%, 30 years$2,197/mo
Property tax and heat$480/mo
Rent recognized -- signed lease ($1,650 + $1,450), 50% offset$1,550/mo

Total debt serviceSigned lease onlyLTB-approved rent
Housing cost after rental offset$1,127$1,047
Car loan$260$260
Total debt service16.9%15.9%

A one-point swing on a $415,000 file is not what decides an approval on its own -- this purchase was never close to a decline either way, and Windsor's own rental vacancy rate only reinforced how little risk either unit carried. What the LTB order actually did was replace a number the tenant no longer owed with the number they did, on a file where getting the documentation right mattered more than the size of the swing.

The solution

A mortgage agent working under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the lease and the LTB order as two separate documents answering two separate questions.

First, requested the LTB's own approval order directly from the seller's property manager. Confirmed the above-guideline increase's exact effective date and approved amount, rather than taking the landlord's word for what the new rent was supposed to be.

Second, confirmed the increase was already in effect, not merely approved. An LTB order approving a future increase and one confirming a rent already payable are different things; only the latter is something a lender can rely on today.

Third, moved the file to a lender whose rental offset policy will credit an LTB-ordered rent once shown the order itself. Not every lender's checklist has a box for that; the ones that do simply asked for the order.

Unit 2's signed lease, unaffected and unchanged
Confirmation the increase's effective date fell before the closing date

№ 05

The outcome

The purchase funded conventionally at 5.05%, qualified on the LTB-approved rent at 15.9% total debt service, with Ontario's land transfer tax on the purchase coming to $4,775.

This is an uninsured, non-owner-occupied purchase, so CMHC's ratio maximums don't apply here; both total-debt-service figures are informational, showing the modest but real effect of using the legally correct rent.

What to take from this file

  • 01A signed lease and the legally payable rent can diverge. An LTB-approved increase takes effect on its own order, not on whenever someone reprints the lease.
  • 02Confirm an increase is in effect, not just approved. A future effective date is not something a lender can credit at today's closing.
  • 03Pull the LTB order itself, not the landlord's summary of it. The order is the only document that actually proves the amount and the date.
  • 04Not every lender's rental-offset policy has a box for an LTB order. Confirm the policy before submitting, not after a file stalls on a documentation gap.
  • 05A modest, legitimate rent increase produces a modest, legitimate ratio change. The point of getting it right is accuracy, not a dramatic swing.

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:

  • 5.05% 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.
