The client
An investor in Norfolk County was switching Property A, a $256,000 mortgage at maturity, away from the lender that also holds a second rental, Property B, financed under the same joint-and-several personal guarantee years earlier.
Property A
$256,000 at maturity
Switching to a new lender
Property B
Separate rental, same original lender
Not part of this transaction
Original guarantee
Joint-and-several, across both properties
Combined household income
$8,500/month
The problem
A lender financing two properties for the same investor will sometimes require one joint-and-several personal guarantee covering both mortgages at once, as its own condition for taking on the relationship -- and that guarantee does not automatically fall away just because one of the two properties is switching to a different lender.
What the new lender needed resolved first
- ▸Property A and Property B had been financed together years earlier under one joint-and-several guarantee spanning both mortgages
- ▸Switching Property A alone would leave that guarantee's status unclear -- still notionally binding the investor to the original lender's exposure on Property B
- ▸The new lender would not register in first position on Property A without confirming what became of the guarantee as it applied to this property
Property A's own numbers were never in question. What held up the switch was a guarantee written for a relationship that was about to become two separate ones.
The numbers
Once the guarantee question was actually resolved, the switch itself was a straightforward rate comparison.
| Staying at the posted rate vs. switching | Amount |
|---|---|
| Balance at maturity | $256,000 |
| Monthly payment | Staying (6.15%) | Switching (4.80%) |
|---|---|---|
| Mortgage payment | $1,760 | $1,565 |
| Difference | -- | $195/mo |
The $195/mo gap between staying and switching was always available on the numbers alone, a savings margin consistent with what mortgage renewal data shows for a borrower moving off a posted rate with no relationship discount -- what actually delayed the switch was confirming, in writing, that the original lender's guarantee no longer reached Property A once it moved. Total debt service on the switch settles at 26.6%, well inside range for an uninsured file.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the guarantee as its own condition to clear, separately from the rate comparison that made the switch worth doing in the first place.
First, confirmed with the original lender exactly what the joint-and-several guarantee covered -- both mortgages together, not either one independently -- and asked directly what would happen to it once Property A switched.
Second, demonstrated that Property B's own equity and income independently supported its existing mortgage, without needing Property A's guarantee behind it for the original lender's comfort.
Third, obtained a written release of the guarantee as it applied to Property A specifically, satisfying the new lender's condition without disturbing Property B's own mortgage or its arrangement with the original lender at all.
The outcome
The switch closed at 4.80%, with the guarantee released as it applied to Property A and total debt service settling at 26.6%.
Because this is an uninsured switch, CMHC's ratio maximums do not apply directly; the 26.6% figure is informational.
What to take from this file
- 01A joint-and-several guarantee written across two properties does not automatically narrow itself just because one property is switching lenders. Confirm its exact scope in the original loan documents before assuming it only ever applied one property at a time.
- 02A new lender may require a guarantee release even on a property whose own numbers are entirely sound, simply because the guarantee's wording reaches beyond that one property.
- 03Demonstrating the other property's independent strength is what actually gets a guarantee released -- not disputing that the guarantee ever existed.
- 04A rate-comparison savings figure and a guarantee-release condition are two separate problems. Solving the second is what lets the first actually close.
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.
- ▸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:
- ▸6.15% / 4.80% rates — rates move daily; neither is a quote.
- ▸the joint-and-several guarantee across both properties — each lender sets its own condition for financing two properties together; requiring one cross-property guarantee is one lender's own practice, not a universal rule.
