Mortgage qualification
Variable income is a history-and-trend problem
Variable income is not “unusable” income. The lender is trying to estimate a sustainable amount rather than assume the strongest recent pay period will repeat forever.
Why variable income gets different treatment from fixed salary
A $90,000 salary can usually be verified as a current annual amount. A borrower who earned $90,000 because of overtime, commission or bonus needs a second question answered: how much of that is likely to recur?
That is why lenders commonly compare historical tax/payroll income with the current year rather than simply annualizing the latest cheque.
Two years is the normal starting point—but not a mechanical promise
In HopeWell's A-lender files, a two-year history is the common starting point for fluctuating income. A simple average of $90,000 and $110,000 is $100,000, but the direction of travel matters.
If the most recent year falls sharply, the lender may use the lower figure or ask why the decline occurred. If the income is rising and the current year supports it, the two-year average is generally easier to defend.
| Year 1 | Year 2 | Simple average | What the lender still asks |
|---|---|---|---|
| $90,000 | $110,000 | $100,000 | Is the rising pattern continuing? |
| $110,000 | $90,000 | $100,000 | Why did income fall, and is $100,000 still sustainable? |
| $70,000 | $130,000 | $100,000 | Was the second year exceptional or repeatable? |
Year-to-date income is the reality check
Historical averages tell the lender what happened. Current year-to-date pay helps show what is happening now. A borrower whose old two-year average is $120,000 but who is on pace for $80,000 this year may not qualify on $120,000 without a credible explanation.
The reverse can also happen: a borrower with a strong current year but limited history may need a lender/program capable of giving more weight to current earnings.
Separate guaranteed base pay from the variable component
If a salesperson has a $60,000 fixed base salary plus commission, the lender can often analyze the $60,000 base under the fixed-income method and the commission under the historical variable-income method. Combining everything into one opaque number can make the file harder to understand.
This separation is especially useful when commission history is shorter than the underlying employment history.
Alternative lenders can sometimes use a different evidence set
A-lender qualification generally emphasizes verified historical income. B lenders can sometimes make sense of a strong current earning pattern using different documentation and a more flexible risk framework, but the trade-off is usually higher pricing and fees.
The Brantford YTD-income purchase is a good example: current earnings mattered because the standard historic-income path did not capture the borrower's present position well enough.
Variable income across two jobs has to be normalized source by source
Do not average the household total without understanding where it came from. One job may be fixed and the other variable; one may have a long history and the other may be new.
The Pickering case shows why separating sources can produce a cleaner qualification analysis.
A clean variable-income file reconciles history to current payroll
Typical evidence includes current job letter/paystub plus T4s, NOAs and sometimes additional payroll history. Commissioned borrowers may need more detail if tax deductions, reimbursed expenses or business-like costs affect the income picture.
Stress the income before you stress the rate
Run the Maximum Mortgage Calculator using the preferred accepted income and again using a lower conservative figure. If a small income reduction destroys qualification, the file has little income cushion even before interest-rate risk is considered.
Commission income can need more analysis than overtime or bonus
A commissioned employee can have a fixed employer and still have income that behaves economically like business income. Historical T4 income may include commissions before the borrower incurs employment expenses; some lender/programs may ask for tax documents that reveal those expenses or otherwise use a specific net/gross methodology.
The important point is not to assume that every dollar appearing on a commission statement is qualifying gross income. Determine the employer/payroll structure, historical taxable income, recurring employment expenses if relevant, and the lender's actual method.
The HopeWell variable-income buffer test
After calculating the lender-acceptable amount, reduce it by 10% and rerun the mortgage. If the file immediately falls outside the required ratios, the borrower is qualifying close to the edge of an income stream that is inherently less predictable.
That does not mean the mortgage is unsuitable, but it changes the conversation. The household may want a smaller mortgage, more liquid savings, fewer other debts or a product with more payment flexibility. A lender's historical average answers a credit question; the buffer test answers a resilience question.
