The problem
The seller's existing tenant had a documented move-out date under their own tenancy agreement, and that date fell a few days after the purchase's originally scheduled closing -- so the buyer and seller signed a short closing extension to let the tenancy actually run its course before vacant possession transferred.
What the extension actually reset
- ▸The purchase price, the mortgage amount, and every underwriting fact about the buyer's own income and credit stayed exactly the same
- ▸The rate hold itself, however, had its own maximum total length -- hold plus any extension -- set by the lender, not tied to the purchase agreement's own closing date
- ▸The short extension alone was enough to push the file's total elapsed time past that ceiling
Nobody re-underwrote anything. The rate hold simply ran out of road.
The numbers
Once the hold reset, the only thing that changed in the file's own math was which rate the qualifying payment used.
| One mortgage, two different rates | Amount |
|---|---|
| Down payment (20%) | $83,000 |
| Base mortgage | $332,000 |
| Contract payment | At the original 4.60% hold | At the reset 4.95% rate |
|---|---|---|
| Monthly contract payment | $1,856 | $1,921 |
| Difference | -- | $65/mo |
At the reset rate, the qualifying payment comes to $2,315/mo, for total debt service of 32.8% -- comfortably inside range, consistent with how lender-type market share data suggests a conventional rental file like this one typically clears at a single lender. The $65/mo difference is the real cost of the reset, not the ratios.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the closing extension and the rate hold as two separate clocks running on two separate rules, not one deadline governing both.
First, called the lender the moment the tenant's own move-out date was known, and asked specifically how much runway remained on the rate hold once the closing extension was factored in -- rather than assuming the hold simply followed the purchase agreement's new date.
Second, got the lender's own maximum hold-extension window in writing. That window, not the purchase agreement's closing date, was the number that actually mattered.
Third, once the numbers showed the extension would run past that window, requalified the file at the reset rate immediately rather than losing more time disputing a rate the lender was never going to honour.
The outcome
The purchase funded at 4.95% once the reset rate was confirmed, with total debt service settling at 32.8%.
Because this file is an uninsured rental purchase, CMHC's ratio maximums do not apply directly; the 32.8% total-debt-service figure is informational.
What to take from this file
- 01A rate hold's own maximum length runs on the lender's clock, not the purchase agreement's. Extending a closing date for an unrelated reason -- like a seller's tenant finishing out a notice period -- can still burn through a hold's own ceiling.
- 02Confirm the hold-extension window in writing before agreeing to any closing extension, not after. The two agreements are governed by entirely different documents.
- 03Losing a hold is a rate problem, not an underwriting problem. Nothing about the buyer's income, credit, or the property changed here -- only which rate the payment used.
- 04Requalifying promptly at the reset rate beats disputing it. Once a lender's own hold window has actually passed, the reset rate is not a negotiating position.
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.
- ▸OSFI — Minimum qualifying rate for uninsured mortgages — the minimum qualifying rate — greater of contract rate + 2% or 5.25%.
- ▸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:
- ▸4.60% / 4.95% rates — rates move daily; neither is a quote.
- ▸the lender's own maximum rate-hold-extension window — each lender sets its own total hold-plus-extension period; there is no universal rule.
- ▸the total-debt-service figure — this is an uninsured rental purchase -- there is no CMHC ratio ceiling; the number is informational.
