The client
An investor is buying a $315,000 Montreal condo as a non-owner-occupied rental, 25% down, with a signed lease at $1,850/mo. Income, credit and the mortgage math were all straightforward from the outset.

$18,000 special assessment
Just levied by the syndicate
The problem
The syndicate's reserve-fund study had just exposed a shortfall, and every unit was levied an $18,000 special assessment for the needed repairs -- payable either as a 36-month installment plan at $500/mo, or as a single lump sum at closing. The lender's policy required counting any ongoing installment as a carrying cost, exactly like the condo fee.
Two ways to pay the same assessment, two different effects on the file
- ▸Paid as a $500/mo installment, the assessment is an ongoing obligation the lender must count in total debt service
- ▸Paid as one lump sum at closing, it is a one-time cash cost with no ongoing carrying-cost effect at all
- ▸The investor's own preliminary budget -- mortgage, condo fee and property tax only -- had never accounted for either option
Neither path changed how much the assessment actually cost in total. What changed was whether that cost showed up in the ratios every month for the next three years, or once, at the closing table.
The numbers
Pricing the file both ways made the choice concrete, and confirmed neither path put the purchase itself at any real risk -- rental market conditions aside, this was a comfortable file either way.
| Carrying the assessment two different ways | Amount |
|---|---|
| Conventional mortgage (75% of purchase price) | $236,250 |
| Rental offset (50% of $1,850 signed lease) | -$925 |
| TDS without the assessment | 15.0% |
| TDS with the $500/mo installment counted | 20.5% |
| Total debt service | Lump sum at closing | Monthly installment |
|---|---|---|
| Mortgage payment, qualifying rate | $1,669 | $1,669 |
| Condo fee | $340 | $340 |
| Special assessment installment | — | $500 |
| Rental offset (50% of lease) | -$925 | -$925 |
| Car loan | $300 | $300 |
| Total debt service | 15.0% | 20.5% |
Both figures pass with room, but the 5.5-point gap is exactly what a lump-sum payment avoids -- a real, quantifiable difference the investor's own preliminary budget had never priced in.
The solution
A courtier hypothécaire (mortgage broker) licensed under Quebec's Act respecting the distribution of financial products and services read the syndicate's disclosure documents before finalizing how the file would be priced.
First, confirmed the special assessment's total amount and both payment options directly with the syndicate. The disclosure package named the $18,000 figure and offered the installment plan as the default, with the lump sum available on request.
Second, priced the file both ways for the investor before any decision was made. Showed the 15.0% versus 20.5% TDS difference plainly, rather than letting the installment plan default through unnoticed.
Third, confirmed with the syndicate that the lump-sum option removed the ongoing obligation entirely, and had the investor pay it in cash at closing. This is a different lever than the usual rental income offset methods comparison, which changes how rent is counted rather than how a cost is paid.
The outcome
The investor paid the $18,000 assessment as a lump sum at closing, funded conventional at 5.10% with total debt service at 15.0%. Quebec's welcome tax on the $315,000 purchase came to $2,836, confirmed in cash alongside the assessment.
Since this file closed at 25% down, it is conventional and uninsured -- there is no CMHC ratio ceiling on either the 15.0% or the 20.5% figure; both are informational, showing the real cost of the two payment choices.
What to take from this file
- 01A condo syndicate's reserve-fund study can surface a real carrying-cost surprise on an otherwise straightforward rental file. Read the disclosure documents before finalizing the numbers, not after.
- 02How an assessment is paid matters as much as how much it is. A monthly installment is an ongoing carrying cost; a lump sum at closing is a one-time cash outlay that never touches the ratios.
- 03Ask the syndicate directly whether a lump-sum alternative to an installment plan exists. Not every syndicate offers one, but many do, and the installment plan is often just the default.
- 04Price the file both ways before the investor commits to either payment option. A 5.5-point TDS difference is worth seeing plainly, even when both numbers would ultimately pass.
- 05A rental purchase's own budget surprises don't always come from the rent side of the ledger. This one came entirely from the building's own capital-repair needs.

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.

- ▸Gouvernement du Québec — Droits sur les mutations immobilières — Quebec's transfer duties ('welcome tax') — 2026 indexed brackets.
- ▸Provincial/territorial mortgage-broker legislation fetched directly (bclaws.gov.bc.ca, legisquebec.gouv.qc.ca, fcaa.gov.sk.ca, web2.gov.mb.ca, nslegislature.ca, assembly.nl.ca) plus FCNB's own site for NB and CanLII's index for PE — see notes for per-province method — provincial mortgage regulators and licence titles.
Illustrative in this file — lender-specific, not rules:
- ▸5.10% contract rate — rates move daily; not a quote.
- ▸the 50% rent offset — each lender publishes its own rental-income offset or add-back treatment; 50% is illustrative of one common convention, not a universal figure.
- ▸the syndicate's lump-sum option — not every condo syndicate offers a lump-sum alternative to an installment special assessment -- this one did.
- ▸financing this purchase as a conventional, uninsured mortgage at 25% down — CMHC's standard homeowner default-insurance product is restricted to owner-occupied properties; a separate, more restrictive insurance product exists for some non-owner-occupied rentals, but its terms were not independently verified for this batch, so this file is priced as conventional rather than relying on that product.
