Two years, one average

a Toronto real estate agent’s commission income after a soft market

A RECO-licensed real estate agent’s strong year and soft year averaged to a monthly income a most-recent-year-only lender wouldn’t use. Re-worked at a two-year-average lender, the same file cleared GDS and TDS insured, with room to spare.

Anonymized illustration. The borrowers, dollar figures, and rates in this file are an illustrative composite — no real client is identifiable, and any rate shown is illustrative, not a quote. The rules are real: every regulatory figure is cited to its source in the Sources section, and the math computes exactly as shown.

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.

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 loanAmount
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.

Adding the 410/mo car lease to the same housing costs is where the two income treatments actually decide the file.

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

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.

Illustrative in this file — lender-specific, not rules:

  • 4.89% contract rate — rates move daily; not a quote.
