The client
The keeping spouse in a Miramichi, New Brunswick separation, buying out the other's share of a matrimonial home appraised at $260,000. An existing $195,000 mortgage and a $50,000 equalization payment, due under the separation agreement, both needed to be financed — qualifying alone on $5,400/month.

The problem
Several mortgage insurers run a spousal buyout program that treats the payout as a purchase for insurance purposes, letting it be financed above the usual 80% refinance ceiling. Treated as a purchase, the file looked eligible for every purchase-side feature — including the 30-year insured amortization first-time buyers and new-build purchases can use.
Why the 30-year amortization wasn't actually available
- ▸The new $245,000 mortgage was, on its face, a purchase transaction under the insurer's spousal-buyout program
- ▸The 30-year insured amortization requires at least one borrower to be a first-time homebuyer, or the property to be newly built
- ▸The keeping spouse had owned and occupied this exact home for years — disqualifying on both counts, regardless of the purchase treatment
The purchase structure and the amortization eligibility are two separate questions, and this file answered the first one "yes" and the second one "no." At only the standard 25-year amortization, TDS came in at 44.1% — over CMHC's 44% maximum.
The numbers
The buyout itself was never in question — only how many years its payment could be spread across, and what that meant for the ratio.
| Structuring the buyout as a purchase | Amount |
|---|---|
| Existing mortgage discharged | $195,000 |
| Equalization payment funded through the mortgage | +$50,000 |
| New mortgage | $245,000 |
| Equity contributed by the keeping spouse | $15,000 |
| CMHC premium at 4.0% (90.01–95% LTV band) | +$9,800 |
| Total insured mortgage | $254,800 |
| Amortization | 25 years (the only one available) | 30 years (never eligible) |
|---|---|---|
| Minimum qualifying rate on a 4.85% contract rate | 6.85% | 6.85% |
| Payment at the qualifying rate | $1,761/mo | $1,653/mo |
| TDS (payment + $230 tax + $110 heat + $280 car loan) ÷ $5,400 income | 44.1% ✗ | — |
The 30-year figure is shown only for comparison — this file was never eligible for it, so its $108/mo saving was never actually available. The longer amortization isn't open to everyone, and a spousal buyout treated as a purchase doesn't get an exception to the first-time-buyer condition just because it's structured as one.
The solution
A mortgage broker working under New Brunswick's licensing framework resized the mortgage instead of chasing an amortization the file could never have.
First, confirmed the 30-year amortization's eligibility condition directly with the insurer, rather than assuming a spousal-buyout purchase automatically qualified. It did not: the keeping spouse's prior ownership and occupancy of this exact home ruled out the first-time-buyer route, and there was no newly-built property to qualify on instead.
Second, went back to the separation agreement itself. With the spouses' agreement, $2,000 of the $50,000 payout was deferred to an unsecured promissory note between them — a negotiated term, not a lender requirement, that reduced the amount needing to be financed through the mortgage.
Third, resized the insured mortgage around the reduced payout, keeping the 25-year amortization the file was always going to have.
The outcome
Approved insured, with the mortgage resized to $243,000 and TDS settling at 43.8% — inside CMHC's 44% maximum once the file was sized to what a genuine 25-year amortization could actually support.
The deferred $2,000 remains an obligation between the two former spouses under the separation agreement, entirely outside the mortgage — it carries no mortgage-registered security and does not affect the lender's file.
What to take from this file
- 01A purchase-structured spousal buyout doesn't automatically clear every purchase-side eligibility condition. The 30-year amortization's first-time-buyer or new-build requirement still applies, even to a buyout run as a purchase.
- 02Check amortization eligibility before pricing the file around it. Assuming the longer amortization would be available cost this file time it didn't need to lose.
- 03A separation agreement can be amended to fit the financing that's actually available. Deferring part of the payout to a promissory note is a negotiated choice between the spouses, not something the lender requires.
- 04The gap here was $108 a month — the exact value of the amortization this file never had. Once that was accepted, the fix was straightforward.
- 05Structuring a buyout as a purchase and qualifying for every purchase-side program are two different questions. Answer both, not just the first one.
