The client
A licensed real estate agent in the Toronto area, self-employed on commission income and registered with the Real Estate Council of Ontario (RECO) — a completely different regulator from the FSRA-licensed mortgage agent placing this file. The two licences are sometimes confused by clients, but they answer to different acts, different regulators, and different rules; RECO governs how the agent trades in real estate, FSRA governs the mortgage professional’s conduct on this application. The buyer’s own two-year commission history tells a story that mortgage broker market-share data would recognize instantly: a strong year followed by a market-wide slowdown.

Credit picture

410/mo lease payment
Purchase
$620,000 detached, Toronto area
Property tax 400/mo; heat estimate 120/mo

The problem
The first lender the file went to runs a straightforward policy for self-employed commission income when the two most recent years diverge sharply: use the most recent year only, on the theory that it is the better predictor of what the borrower earns going forward. That policy is common and defensible — and on this file, in a year the wider market cooled, it very nearly killed the deal.
The most-recent-year-only arithmetic
- ▸Income used: $96,000 (year two only, 8,000/mo)
- ▸Qualifying payment at MQR 6.89%: 3,990/mo, plus tax and heat
- ▸TDS: 61.5% — against CMHC’s 44% maximum. Declined.
Nothing about the borrower’s file was thin or undocumented — two full years of T1s, NOAs, and a brokerage statement of commission earned were all on the table. The problem was entirely the averaging rule, the same tension covered in how lenders actually average commission income: a single soft year, even inside a normal seasonal swing, can override a much stronger prior year if the lender’s policy says so.
The numbers
At 10% down this is an insured file, so CMHC’s maximums — GDS 39%, TDS 44% — are hard limits, not lender preferences.
| Structuring the insured loan | Amount |
|---|---|
| Purchase price | $620,000 |
| Down payment (10%) | −$62,000 |
| Base mortgage (90% LTV) | $558,000 |
| CMHC premium — 3.10% in the 85.01–90% LTV band, capitalized | +$17,298 |
| Total insured mortgage | $575,298 |
The minimum down payment at this price is 5% of the first $500,000 plus 10% of the remainder — $37,000 here — because the price sits above the $500,000 tier boundary; the client’s $62,000 clears that minimum comfortably.
| Rate & payments | Figure |
|---|---|
| Contract rate — 5-year fixed (illustrative, not a quote) | 4.89% |
| Minimum qualifying rate — greater of contract + 2% and 5.25% | 6.89% |
| Monthly P&I at the qualifying rate — the ratios run on this | 3,990 |
| Monthly P&I at the contract rate — what they actually pay | 3,310 |
GDS — the same under either income treatment
| GDS | Under year-two-only income | Under the two-year average |
|---|---|---|
| Housing costs (P&I + tax + heat) | $4,510 | $4,510 |
| Income used | 8,000/mo | 12,750/mo |
| GDS | 56.4% | 35.4% |
TDS — where the two policies part ways
Adding the 410/mo car lease to the same housing costs is where the two income treatments actually decide the file.
| TDS | Year-two-only | Two-year average |
|---|---|---|
| Income used | 8,000/mo | 12,750/mo |
| TDS vs. the 44% cap | 61.5% ✗ | 38.6% ✓ |
The solution
The FSRA-licensed mortgage agent working the file did two things, in order.
First, confirmed the shape of the decline. A 36-point swing between two commission years is exactly the pattern covered in a self-employed borrower on a two-year average, start to funded — not every softer year needs to be treated as the new normal, and the file’s brokerage-issued commission statement showed active listings already back near the year-one pace.
Second, moved the file to a lender whose self-employed policy defaults to a straight two-year average rather than a most-recent-year-only test, submitting both years’ T1s, NOAs, and the brokerage statement together so the underwriter saw the full picture at once, not a single soft data point in isolation.
The outcome & the closing math
Approved and funded insured at 90% LTV on a 5-year fixed term, 25-year amortization. The add-back conventions that complicate rental files don’t apply here — this file lived or died entirely on which two numbers got averaged into one.
| Cash due at closing (beyond the down payment) | Amount |
|---|---|
| Toronto land transfer tax on $620,000 — provincial LTT mirrored by the municipal MLTT, doubling the marginal brackets up to $2,000,000 | $17,750 |
| Ontario RST on the insurance premium — 8% × $17,298; the premium itself is capitalized, but the tax on it is cash at closing | $1,384 |
| Legal fees, title insurance & adjustments | varies |
What to take from this file
- 01A self-employed averaging policy is a lender choice, not a regulatory rule. The identical two years of T1s produced a decline at one lender and an approval at another — know which policy you’re walking into before you submit.
- 02A soft year is not automatically the new baseline. Corroborating evidence — a brokerage statement, a pipeline of active listings — can support treating a downturn as temporary rather than structural.
- 03The ratios run at the qualifying rate, not the contract rate. This file qualifies at 6.89% and pays at 4.89% — a gap that matters for the ratio math even though it never appears on the client’s payment statement.
- 04Two different professional licences, two different regulators. A RECO-licensed real estate agent and an FSRA-licensed mortgage agent are never the same role, even on a file where both happen to be the same transaction’s two professionals.
- 05Budget the closing cash, not just the down payment. Toronto’s doubled land transfer tax plus the RST on the premium added $19,134 in cash before legal fees.
