You closed a strong year. Your W-2 shows solid earnings, but a significant portion came from commissions, bonuses, or override pay — not a flat salary. When you sit down with a lender and hand over your tax returns, the conversation gets complicated fast. Deductions that reduced your tax bill now appear to reduce your qualifying income. Your income looks inconsistent on paper even when your career trajectory is clearly upward.
This is one of the most common frustrations for commission-driven sales professionals trying to buy or refinance a home in Fort Lauderdale and across South Florida. The good news is that lenders have developed real pathways for people in your situation. The challenge is knowing which path fits your income structure.
Why Traditional Loan Underwriting Can Feel Like It Was Built for Someone Else
Conventional mortgage underwriting was designed around salaried employees. If you earn a fixed paycheck every two weeks, your income is easy to document and easy to verify. Commission-only earners — whether in medical device sales, technology, real estate, financial services, or any other field — often have a more complex picture.
Lenders look at your adjusted gross income from your tax returns, not your gross earnings. If you write off a home office, mileage, equipment, or other business expenses, those deductions lower the number an underwriter uses to calculate what you can borrow. It does not mean you cannot qualify. It means the documentation process requires more care and more context.
Understanding how your income will be calculated before you apply is one of the most useful things you can do. You can explore loan programs for self-employed and commission-based borrowers to get a sense of what options may fit your situation.
How Lenders Calculate Commission Income
For most loan programs, lenders average your commission income over a 24-month period using your tax returns. If year one was lower and year two was higher, they typically average the two. If your income is trending downward, some lenders may use the lower of the two years, which is worth knowing in advance.
If you are a W-2 employee who also receives commissions, your employer may need to verify that the commission structure is likely to continue. A letter from your employer or a copy of your commission agreement can support your file.
If you work as an independent contractor and receive 1099 income, you are generally treated more like a self-employed borrower. That means your net income after business deductions is what counts, not the total on your 1099s. Some loan programs allow bank statement documentation as an alternative, which can reflect a clearer picture of your actual cash flow.
A Note on the Shift Toward 100% Commission Roles
A growing number of sales professionals are moving away from base-plus-commission structures toward 100% commission arrangements, particularly in real estate and independent sales. This shift can mean higher earning potential, but it also changes how lenders view your income. If you are newly in a 100% commission role, the two-year history requirement becomes especially important. You can learn more about how mortgage options for sales professionals account for these structures.
Loan Programs That May Work for Commission Earners
Not every loan program handles commission income the same way. Here are a few worth understanding.
Conventional loans follow Fannie Mae or Freddie Mac guidelines, which allow commission income with proper documentation. These programs often require a two-year history of commission earnings and may average or use the lower of two years depending on income trends.
FHA loans are government-backed and can be more flexible on credit, but they still require documented, stable income. They may be a fit if you have a shorter commission history or are rebuilding credit alongside variable earnings.
Bank statement loans are a non-QM (non-qualified mortgage) option that uses 12 or 24 months of personal or business bank statements instead of tax returns. This can be useful if your tax returns significantly understate your actual cash flow due to legitimate deductions. These programs exist outside conventional guidelines and typically have different qualification criteria.
Asset-based or asset depletion loans may be an option if you have substantial savings or investment accounts and want to use those assets to support your qualifying income.
Each of these programs has trade-offs. Jim Blackburn, NMLS #1072866, can walk you through which structure makes sense given your specific income documentation and financial profile.
What You Can Do Before You Apply
There are practical steps you can take right now that will make the process smoother.
First, gather your last two years of federal tax returns, including all schedules. If you have a CPA or tax professional, let them know you are planning to apply for a mortgage — they may be able to provide a letter explaining your income structure or any significant deductions.
Second, pull together your most recent pay stubs or 1099s, and any commission agreements or employer letters that describe your compensation structure.
Third, review your bank statements. Lenders may ask for two to three months of statements at minimum. If you are applying for a bank statement loan, you will need 12 to 24 months.
Finally, use the mortgage calculators to get a rough sense of what purchase price range aligns with your documented income. This can help you set realistic expectations before you start shopping for homes.
Timing and the Two-Year Rule
One of the most common surprises for commission earners is the two-year history requirement. If you recently switched into a commission-only role — even at a higher earning level — some lenders will want to see that income sustained for two full years before counting it.
There are exceptions. If you moved into a commission role within the same field and your income is clearly documented and consistent, some programs may allow a shorter history. This is where working with someone who understands commission-based income structures matters.
If you are not quite at the two-year mark, it may be worth planning ahead. Understanding the eight steps to buying a home can help you map out a timeline that works with your income history rather than against it.
Working With a Lender Who Understands Your Income
Commission income is not a red flag. It is a documentation challenge, and it is one that experienced mortgage professionals navigate regularly. The difference between a smooth process and a frustrating one often comes down to who is reviewing your file and how well they understand variable income structures.
