How Commission Income Is Used to Qualify for a Mortgage (And When It Hurts You)

Commission income is one of the most common income types I see in Bakersfield, real estate agents, car salespeople, insurance producers, oil field equipment salespeople, and dozens of other professions earn all or part of their pay in commission. The mortgage qualification rules for commission income are straightforward once you understand them, but there are patterns that help and patterns that hurt.

The Two-Year Average Rule

For commission income, whether you're W-2 with commission or self-employed, the standard mortgage guideline requires a two-year history and uses the two-year average to calculate qualifying income. If you earned $80,000 in Year 1 and $100,000 in Year 2, your qualifying income is $90,000. That average is what determines your maximum loan amount, regardless of what your most recent year showed.

When Declining Income Becomes a Problem

Here's where commission income gets complicated. If your Year 2 income is lower than Year 1, even if you're still earning well, lenders often take the lower year as the qualifying figure rather than the average. This is the declining income test. If you earned $120,000 in Year 1 and $90,000 in Year 2, many lenders will use $90,000, not $105,000. If the decline is significant, the lender may not use commission income at all until the trend stabilizes. An upward trend almost always helps; a downward trend almost always hurts.

Base Salary vs. Commission Components

If you have a W-2 job with both a base salary and commission, the base salary qualifies immediately, it's fixed and predictable. Commission history is required for the variable portion. If you've been at your current job for one year or less, the commission component may not qualify yet. If you have two or more years at the same employer with documented commission history, both components can be used. If you recently changed employers but do the same type of work, some lenders will bridge the history.

Self-Employed vs. W-2 Commission Earners

W-2 commission earners are treated differently from self-employed commission earners. W-2 commission earners get a tax form from their employer, the income is visible on the W-2 and on the tax return. Self-employed commission earners run their commission through a business entity and the income appears on Schedule C. The standard self-employment qualification rules apply, two years of returns, net income after write-offs. W-2 commission is generally easier to document and qualify.

Strategies for Commission Earners Approaching a Purchase

Timing matters more for commission earners than for salaried employees. If you had a strong year recently and expect the next year to be consistent or better, buying now gives you the best qualifying picture. If you're in a down year, waiting until you have a full strong year on your return may significantly improve your qualifying income. If you're planning a major purchase, talk to me 12 months out so we can plan the timing around your income history.

Commission Income on the Loan Application

On the mortgage application, commission income is declared separately from base salary. It requires the last two years of W-2s, the last two years of federal tax returns (even for W-2 employees, because commission earners often have business deductions on Schedule A that affect the picture), and year-to-date pay stubs showing current commission earnings. If your YTD commission is significantly below the two-year average pace, the lender will want to understand why.

Common Mistake

Assuming your highest-earning year is your qualifying income. If you had a $150,000 commission year followed by an $80,000 year, you don't qualify on $150,000, or even on the $115,000 average. Because Year 2 declined from Year 1, many lenders will use $80,000 as the qualifying income. Understanding how the declining income test works before you apply, and timing your purchase accordingly, can make a significant difference in what loan you're approved for.

Bottom Line

Commission earners absolutely qualify for mortgages with proper documentation. The two-year average is the standard, but the declining income test means that a recent down year can significantly reduce your qualifying income. If your commission history is strong and trending upward, you're in good position. If last year was weaker than the year before, talk to me about timing and strategy before you apply.
