The client
A homeowner in Nelson who had been on a private mortgage for three years, renewing it annually because a debt-service ratio that would not clear an A-lender's practical benchmark kept ruling out every conventional option. The equity was never the problem — the loan sat at a conservative 60% loan-to-value throughout. What kept the file on the private market, renewal after renewal, was the ratio, and every renewal made the private lender's terms the only ones actually on the table.

The problem
Twice before, this file had been shopped to A-lenders and twice declined on debt-service ratios — not on the equity, which was never in question at 60% loan-to-value, and not on credit, which was clean throughout. Each decline sent the file back to the same private lender for another one-year term, and each renewal came with its own fee, charged on the full balance. Private lenders are a small but persistent slice of Canada's mortgage market share by lender type, and a treadmill like this one is exactly why that slice never shrinks to zero.
The cost of the treadmill
- ▸Renewal fee on the $375,000 balance, each of three renewals: $7,500
- ▸Three renewals, cumulative: $22,500 — paid without reducing the principal by a single dollar
- ▸Interest-only payment throughout: $3,122/month at 9.99%, none of it amortizing
The arithmetic of an interest-only private mortgage is unforgiving on a treadmill like this one: three years of payments and three renewal fees left the balance exactly where it started, while the private lender collected roughly $22,500 for the privilege of not lending anything new.
The numbers
What changed between the second decline and this attempt was not the equity or the property — it was the debt-service math. A reduced car payment and two additional years of stable income finally brought the ratios inside the range an A-lender would accept.
| The private position, before the exit | Amount |
|---|---|
| Home value | $625,000 |
| Private mortgage balance | $375,000 |
| Loan-to-value | 60.0% |
| The private cost, three renewals | Figure |
|---|---|
| Renewal fee per term (illustrative, 2% of the balance) | $7,500 |
| Interest-only payment throughout, at 9.99% | $3,122/mo |
| Cumulative renewal fees across three terms | $22,500 |
Qualifying the A-lender refinance
| Rate & payments | Figure |
|---|---|
| Contract rate — A-lender (illustrative, not a quote) | 4.59% |
| Minimum qualifying rate — contract + 2% | 6.59% |
| Monthly P&I at the qualifying rate — the ratios run on this | $2,532 |
| Monthly P&I at the contract rate — what is actually paid | $2,094 |
| TDS at exit | Monthly |
|---|---|
| P&I at the qualifying rate | $2,532 |
| Property tax | $295 |
| Heat (lender-standard estimate) | $150 |
| Car loan | $310 |
| Total $3,287 ÷ income $10,500 → TDS 31.3% | ✓ |
The relief is real but modest at contract rates — $3,122 interest-only versus $2,094 amortizing is a $1,028 monthly drop — and, unlike the private payment, every dollar of the new payment reduces the balance. Three years of paying $3,122 a month and being no closer to the mortgage's end is a materially different position than the one this refinance puts the homeowner in.
The solution
A BCFSA-licensed submortgage broker treated the third attempt differently from the first two: it re-tested the ratios before shopping the file, rather than shopping the file and hoping the ratios would hold.
First, re-ran the debt-service math against current numbers rather than assuming the prior declines still applied. Two years of income growth and a materially smaller car payment had moved TDS from a decline into a pass at the practical benchmark, even though the property and the balance were unchanged.
Second, shopped the file to an A-lender only once the ratios were confirmed to clear — the sequence set out in moving a private mortgage back to an A-lender, step by step. A third decline would have meant a fourth private renewal and another $7,500 fee.
Third, discharged the private mortgage in full at the refinance closing, ending the renewal cycle rather than negotiating a fourth term. The broader spectrum this file moved across — and why the same balance qualifies so differently at each stage — is set out in A-lender vs. B-lender vs. private lender.
The outcome & the exit
The private mortgage was discharged in full, the renewal cycle ended, and the balance now amortizes on a conventional term rather than resetting annually at a private rate.
British Columbia's total debt service ratio was the single variable that kept this file on the private market for three years — not the equity, not the credit, and not the property. Once it cleared, everything else about the file was already in order.
What to take from this file
- 01A private-lender file is not always an equity problem. This one sat at a conservative 60% loan-to-value the entire time — the debt-service ratio was the obstacle, and it is worth re-testing before assuming the file is stuck.
- 02An interest-only renewal cycle is a cost, not a holding pattern. Three years and $22,500 in fees left the $375,000 balance exactly where it started.
- 03Re-run the ratio math before re-shopping the file, not after. A repeat decline costs another private renewal fee; confirming the numbers first avoids that.
- 04Small changes compound on a debt-service ratio. A lower car payment and two more years of income were what finally moved this file from decline to approval, not a change in the mortgage itself.
- 05Discharge the private charge completely at the exit. A partial exit that leaves any private balance outstanding keeps the renewal-fee exposure alive.
