The problem
A purchase agreement's financing condition exists to let a buyer walk away, deposit intact, if the mortgage does not come through in time. Waiving it -- a levee de condition -- is a normal step once financing is actually secured. It is a different thing entirely when a buyer's agent has it signed to strengthen a competing offer, ahead of the lender's own approval catching up.
What was actually true when the condition was waived
- ▸The lender's file on the self-employment income documentation was at conditional approval, not a firm commitment
- ▸The buyer's agent, trying to win a multiple-offer scenario, had the buyer sign the waiver believing the file was 'basically approved'
- ▸For 9 days, the deposit sat exposed with no financing condition left to fall back on if the file was delayed or declined
Nothing about the buyer's income was actually in doubt. The risk was entirely in the sequence -- the condition was gone before the approval that was supposed to justify removing it.
The numbers
Once discovered, the ratios themselves were never close to a problem -- confirming that was the easy part of fixing this file.
| The self-employed purchase, correctly sequenced | Amount |
|---|---|
| Base mortgage (90% of purchase price) | $406,800 |
| CMHC premium (3.10% at 90% LTV) | +$12,611 |
| Total insured mortgage | $419,411 |
| Ratio check at the qualifying rate | Figure |
|---|---|
| Payment at the qualifying rate (6.90%), 25 years | $2,912/mo |
| GDS (payment + $310 tax + $120 heat) ÷ $8,700 income | 38.4% |
| TDS (GDS numerator + $260 car loan) ÷ $8,700 income | 41.4% |
38.4% and 41.4% sit comfortably inside CMHC's 39% GDS and 44% TDS maximums, in line with what mortgage broker market share data suggests a self-employed file this size typically clears through the broker channel. The file was never going to be declined on its own facts -- the exposure was entirely the 9 days the deposit sat with no financing condition behind it.
The solution
A courtier hypothecaire licensed under Quebec's Act respecting the distribution of financial products and services treated the premature waiver as an underwriting emergency, not a paperwork formality.
First, on discovering the waiver, immediately escalated the outstanding self-employment documents -- current Notice of Assessment and business financials -- for expedited underwriting rather than waiting on the lender's normal queue.
Second, obtained a firm commitment days ahead of the closing date, closing the gap the premature waiver had opened.
Third, documented the full sequence for the client and the file, including exactly when the condition had been waived relative to when the commitment actually issued.
The outcome
The purchase funded insured at 38.4% GDS and 41.4% TDS, with Quebec's welcome tax on the $452,000 purchase coming to $4,890.
The ratios were comfortably inside CMHC's maximums throughout; the real outcome of this file was the practice change, not the arithmetic -- a financing condition is never waived again before a firm commitment is actually in hand.
What to take from this file
- 01A financing condition should never be waived on the strength of a conditional approval alone. Only a firm commitment justifies removing the buyer's own protection.
- 02A competing-offer strategy that removes a buyer's financing condition early is a real deposit risk, not a paperwork detail. Confirm exactly what stage the lender's file is actually at before any waiver is signed.
- 03Strong income documentation does not protect a deposit if the condition meant to protect it is already gone. The two are separate risks, and only one of them is about the numbers.
- 04Once a premature waiver is discovered, speed matters more than blame. Escalating the outstanding documents immediately closed the exposure faster than any after-the-fact analysis would have.
