The problem
Financing the entire $200,000 equalization payment through one new first mortgage was the obvious first structure to try — and the one that failed.
The full-cash structure
- ▸New mortgage needed: existing $150,000 plus the full $200,000 equalization = $350,000
- ▸Qualifying payment on that balance alone
- ▸TDS on the remaining spouse's income alone: 44.8% — over the file's ceiling
A second mortgage instead of a larger refinance is a well-established structure when a single new loan can't cover a full amount — it's used routinely between unrelated buyers and sellers. Nothing about it changes because the second lienholder happens to be the departing spouse rather than a stranger.
The numbers
The equalization amount itself never changed at $200,000 — only how it was split between cash at closing and a note carried by the departing spouse.
| The split structure | Amount |
|---|---|
| Existing mortgage balance | $150,000 |
| Cash portion of equalization (new first mortgage) | +$40,000 |
| New first mortgage | $190,000 |
| Vendor take-back second (departing spouse) | $160,000 |
| Structure | Full cash (one mortgage) | Split (first + VTB second) |
|---|---|---|
| New first mortgage balance | $350,000 | $190,000 |
| Qualifying payment, first mortgage (25yr, 6.65%) | $2,376/mo | $1,290/mo |
| Vendor take-back second ($160,000, 4.75%, 25yr) | — | $908/mo |
| Combined qualifying payment | $2,376/mo | $2,198/mo |
| TDS (payment + $260 tax + $120 heat ÷ $6,150 income) | 44.8% | 41.9% |
The split structure's combined payment is lower than the full-cash structure's single payment, even though it covers the identical $350,000 of total obligation — the longer, separately-priced vendor take-back second simply spreads part of the payout over its own amortization instead of adding it all to one loan at once.
The solution
A Financial and Consumer Services Commission of New Brunswick-licensed mortgage broker restructured the payout rather than the ratios.
First, confirmed the full-cash structure's TDS failure before proposing anything else, so both spouses understood exactly why a single new mortgage covering the whole equalization wasn't going to work.
Second, proposed splitting the $200,000 into a $40,000 cash portion (funded through a modest, qualifying new first mortgage) and a $160,000 registered second mortgage the departing spouse would carry themselves, amortized over 25 years.
Third, had both spouses' own lawyers document the second mortgage's terms independently of the separation agreement's equalization clause — a registered charge with its own rate, term and remedies on default, not an informal promise between former spouses.
The outcome
TDS falls from 44.8% on the full-cash structure to 41.9% on the split structure, and the departing spouse still receives their full $200,000 — $40,000 at closing, $160,000 amortizing on the registered second.
How a transfer of interest between separating spouses is treated for provincial transfer-tax purposes varies, and needs confirmation with the closing lawyer before relying on any exemption — that piece of this file was left to counsel, not quantified here.
What to take from this file
- 01A full equalization payout doesn't have to fund through one mortgage. Splitting it between cash and a second mortgage is a standard financing structure, not a special divorce workaround.
- 02The departing spouse becomes an ordinary secured lender on the second. Document the second mortgage on its own commercial terms, separate from the emotional context of the separation agreement.
- 03A longer-amortized second can lower the combined payment below a shorter, larger single mortgage. Run both structures before assuming the obvious one is the only option.
- 04Get independent legal advice on both sides of the second mortgage. A registered charge between former spouses needs the same clarity on default and remedies as one between strangers.
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%.
- ▸CMHC — CMHC Reviews Underwriting Criteria — GDS 39% / TDS 44% maximums and the 600 credit-score floor for insured files.
- ▸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:
- ▸4.65% first-mortgage rate / 4.75% vendor take-back rate — rates move daily; neither is a quote.
- ▸the 25-year vendor take-back amortization — a private second mortgage between former spouses can be structured on whatever term and amortization both parties agree to -- this is one workable structure, not a rule.
- ▸the TDS figures — this file is uninsured, so there is no CMHC ratio ceiling -- the numbers show the gap the split structure closes, not a regulatory pass/fail line.
