The client
Homeowners in Edmonton who took a private second mortgage a little over a year ago to cover a shortfall on a self-employment tax bill, on top of an existing A-lender first mortgage — a bridge, never intended to be the destination, but one that only works if there is a documented exit strategy from day one.
The private second was interest-only, priced well above the first mortgage’s rate, and it was never going to age well sitting behind an existing second mortgage structure combined with unrelated credit card debt from the same period.

The problem
Stacked together, the first mortgage payment, the private second’s interest-only payment, the card minimums and the personal loan pushed TDS to 46.2% — too high for any A-lender exit while all four obligations remained on the file at once.
The combined obligations, before cleanup
- ▸First mortgage: $2,150/mo; private second (interest-only): $595/mo
- ▸Card minimums: $660/mo; personal loan: $380/mo
- ▸TDS against $9,400/mo income, plus tax and heat: 46.2% — no A-lender would exit the private second at this ratio
The private second itself was never the real obstacle — a clean private-to-A exit at this combined LTV is routine. The unsecured debt sitting alongside it was what kept the combined ratios too high for any A-lender to consolidate the file.
The numbers
The private term gave the borrowers a fixed window to clean up the unsecured side of the file before the exit needed to happen — a pattern that shows up often enough in mortgage arrears rate recovery data that a planned private-to-A exit, done properly, rarely ends in default.
| Before and after the debt cleanup | Amount |
|---|---|
| Combined obligations before cleanup | $3,785/mo |
| TDS before cleanup | 46.2% |
| Consolidated A-lender mortgage | $405,000 |
| TDS after cleanup, on the consolidated mortgage | 37.3% |
| Rate & payments | Figure |
|---|---|
| Contract rate — 5-year fixed (illustrative, not a quote) | 5.09% |
| Minimum qualifying rate — greater of contract + 2% and 5.25% | 7.09% |
| Monthly P&I at the qualifying rate — the ratios run on this | $2,859 |
| Monthly P&I at the contract rate — what they actually pay | $2,376 |
Over the fourteen months of the private term, the borrowers paid the unsecured debt down to a single $90/month card balance. GDS on the consolidated $405,000 mortgage comes to 36.4%, and TDS, with that last card payment included, comes to 37.3% — both comfortably clear of CMHC's 39%/44% ceiling, even though this consolidated loan is uninsured and not bound by it directly.
The solution
An RECA-licensed Alberta mortgage broker planned the exit from the day the private second funded, not as an afterthought once the term was nearly up.
First, set specific debt-paydown milestones timed to the private term. Rather than a general instruction to pay down debt, the plan set monthly targets so the unsecured balances would be manageable well before the maturity date, not scrambled at the last month.
Second, tracked the combined LTV throughout the term. At 75% combined against the home’s value, the exit loan had room within standard A-lender conventional lending limits, which meant the debt cleanup, not the LTV, was always the binding constraint.
Third, lined up the A-lender refinance in advance of maturity, using the same private exit strategy planning that any private file needs from the outset, confirmed against what actually makes a private exit strategy real rather than aspirational.
The outcome
Refinanced into a single $405,000 conventional A-lender mortgage at 75% combined LTV, paying off both the first mortgage and the private second in one transaction. The private lender was repaid in full on schedule, and the household’s three separate obligations — first mortgage, private second, and unsecured debt — became one payment.
What to take from this file
- 01A private second is rarely the real obstacle to an A-lender exit — the unsecured debt sitting beside it usually is. Combined TDS, not the private mortgage alone, decided this file.
- 02Plan the exit the day the private mortgage funds, not the month before it matures. Specific paydown milestones timed to the private term turn a hopeful exit into a planned one.
- 03Combined LTV and combined TDS are two separate tests — know which one is binding. This file had plenty of LTV room throughout; the debt ratios were the actual constraint.
- 04The approval math on the exit runs at the qualifying rate, not the contract rate. This file qualifies at 7.09% and pays at 5.09%.
- 05A private mortgage without a written exit plan is a bridge with no far bank. Every private placement needs one from the start, not as a rescue measure later.
