How to Qualify for a Mortgage With Commission Income

A strong year of sales can feel like proof that you are ready to buy a home. A lender sees it differently: they need to know whether that income is stable enough to support a mortgage through slower months, market changes, or a job transition. You can qualify mortgage with commission income in Alberta, but the application needs to show a clear, documented pattern rather than one exceptional pay period.

Commission-based borrowers include real estate professionals, sales representatives, financial advisors, automotive salespeople, recruiters, and many other high-performing Albertans. Their income may be substantial, yet the path to approval is often less straightforward than it is for a salaried employee. Good preparation makes a meaningful difference.

How lenders assess commission income for a mortgage

Most lenders look for a two-year history of commission income. Rather than qualifying you based on your best recent year alone, they commonly use an average of your last two years of reported income. If your income has declined, a lender may use the lower, more conservative figure instead.

For example, if your taxable income was $85,000 last year and $105,000 the year before, a lender may use an average of $95,000. If the current year is tracking well above those figures, that can support the overall file, but it does not always replace the lender's requirement for documented history.

The exact approach depends on the lender, the mortgage product, your down payment, and how the income is paid. Some borrowers receive a base salary plus commissions, while others earn nearly all of their income from commissions. A steady base salary can help, but lenders will still review the commission portion carefully if it is needed to qualify.

Lenders also look beyond income. Your credit history, existing debt payments, down payment source, property type, and employment stability all affect the decision. This is why a commission earner with a modest income but low debt can sometimes qualify more comfortably than someone with higher earnings and large monthly obligations.

Documents you will usually need

Commission income must be verifiable. Having your documents organized before you make an offer can prevent delays and help establish a realistic purchase budget.

Your mortgage application will commonly require your two most recent Notices of Assessment from the Canada Revenue Agency and the matching T1 General tax returns. Lenders often request recent pay stubs, a letter of employment confirming your role, compensation structure, and start date, plus year-to-date income details.

Bank statements may also be needed to confirm your down payment, especially when funds have been transferred between accounts or received from a gift. If commissions are paid directly into a business account, additional business banking records or financial statements may be required. Keep any large deposits easy to explain. A lender is not questioning your success - they simply need to meet verification and anti-money-laundering requirements.

Be careful with tax deductions

Many commission earners claim legitimate work expenses, such as vehicle costs, marketing, licensing, home office expenses, and professional fees. These deductions can lower your taxable income, which may lower the income a lender can use for mortgage qualification.

That does not mean you should avoid valid deductions. It means mortgage planning and tax planning should be considered together, particularly if you expect to buy or refinance within the next one to two years. Some lenders may add back certain non-cash deductions, such as depreciation, where their guidelines allow it. They will not automatically add back every business expense.

A broker can review your tax returns early and help you understand how different lenders may interpret the income. That conversation is most useful before you start shopping for homes, not after you have removed financing conditions.

How much mortgage can you qualify for?

Lenders use debt service ratios to compare your income with your housing costs and other debts. Housing costs generally include the mortgage payment, property taxes, heating, and in some cases a portion of condominium fees. Other debts can include vehicle loans, lines of credit, credit cards, student loans, and support payments.

For many applications, the mortgage payment is also tested at a qualifying rate that may be higher than your contract rate. This stress test is designed to confirm you could continue making payments if rates rise at renewal. It can reduce the maximum mortgage amount, even when the payment you expect to make feels manageable today.

The practical lesson is simple: do not base your home budget on gross commission income or an online calculator alone. A proper pre-approval should account for the income figure a lender is likely to accept, current debts, down payment, and the qualifying rate.

Steps that can strengthen a commission-income application

The goal is not to make your file look perfect. It is to make it clear, consistent, and easy for an underwriter to verify.

First, avoid changing jobs or compensation structures just before applying if you can. Moving from a salary position to a fully commissioned role may reset the income history a lender needs. A move within the same industry can sometimes be workable, especially with a strong track record, but it deserves a review before you make the change.

Second, keep personal and business finances well documented. Deposit commission cheques or electronic payments consistently, retain pay statements, and avoid relying heavily on cash transactions that are difficult to verify. If your income is trending upward, year-to-date records can help show momentum alongside your tax history.

Third, reduce high-interest revolving debt where possible. Credit card balances and unsecured lines of credit can have a larger effect on qualification than many buyers expect because lenders calculate assumed monthly payments. Paying down a balance may improve your debt ratios and your credit profile at the same time.

Finally, protect your credit during the mortgage process. Make every payment on time, avoid opening several new accounts, and do not finance a vehicle or major purchase before your mortgage closes. Even a well-qualified borrower can create an unnecessary issue by adding debt between approval and possession.

When a two-year average is not available

A shorter history does not automatically mean you cannot buy a home. Newer commission earners, recent graduates, people returning to work, and professionals who have changed industries may have options, but lender choices can be narrower.

A lender may consider previous experience in a related field, a guaranteed base income, an employment contract, or a documented compensation plan. A larger down payment, strong credit, and low debt can also improve the overall application. In some cases, waiting until another tax year is available may lead to better rates, more lender options, or a higher purchase budget.

There are also alternative mortgage solutions for borrowers whose taxable income does not reflect their true cash flow. These options can be useful, but they may involve a higher rate, lender fees, or a larger down payment. They should be evaluated carefully, not treated as a first choice when a traditional mortgage is within reach.

Pre-approval matters more when income varies

A pre-approval gives you a clearer view of what you may qualify for before you make an offer. For commission earners, it is also an opportunity to identify documentation gaps and compare lenders with different income-verification policies.

Keep in mind that a pre-approval is not the same as final approval. The lender will still review the property, confirm your documents, and reassess the file before funding. If your income, debt, employment, or down payment changes, the result can change as well.

Working with a mortgage broker can be particularly helpful because one application can be matched with lenders that are comfortable with commission-based borrowers. Alberta Mortgage Services can help review the story behind your income, explain what documents are needed, and provide clear guidance without pressure.

Common questions about qualifying with commission income

Can commission income count toward a down payment?

Yes. Commission income can be used to build your down payment, provided the funds are in an acceptable account and can be documented. Lenders generally want to see a history of the funds and an explanation for any large recent deposits.

Can I qualify if my commission income increased sharply this year?

Possibly, but most lenders still rely primarily on filed tax documents. Recent income records can support your application, especially when the increase is consistent with a stable role and industry, but the lender may not use all of that increase until it appears on your tax return.

What if my income dropped last year?

It depends on why it dropped and whether the decline appears temporary or ongoing. A lender may use the lower year, ask for year-to-date evidence, or require a stronger explanation. Being upfront about the reason is better than hoping it will not be noticed.

If homeownership is part of your plan, start gathering your tax documents and income records before you begin viewing properties. A calm, early review can turn variable income from a source of uncertainty into a well-supported mortgage application.
