If your paycheck depends on commission, a lender can’t just glance at last month’s stub to approve your mortgage. They need a documented income pattern spanning years, not weeks. This guide, from Stafford broker Duane Buziak, walks through how underwriters actually calculate commission income, what paperwork to gather, a worked local example, and the mistakes that most often delay closing for buyers in Garrisonville, Embrey Mill, North Stafford, and beyond.
How Underwriters Actually Calculate Commission Income
Most conventional and government loan programs require averaging the most recent two years of commission income rather than counting a single strong month, quarter, or even a great final stretch before application. Underwriters pull two years of tax returns and calculate a monthly average, then compare that figure to year-to-date pay documentation to confirm the trend is stable or increasing. This approach is spelled out in guidance like the Fannie Mae Selling Guide, which treats commission as variable income requiring a documented history before it counts toward qualifying income.
Commission reported on a 1099 is generally treated like self-employment income and reviewed alongside Schedule C or Schedule 1 filings, even when the borrower technically works as a W-2 employee whose pay is mostly commission-based. That means underwriters aren’t just looking at gross commission checks. They’re looking at what was actually reported to the IRS after deductions, which can be meaningfully lower than what shows up in a bank account. The IRS Schedule C instructions outline exactly which expense categories get deducted, and those same deductions often reduce qualifying income on a mortgage application.
A documented downward trend in year-over-year commission can trigger extra scrutiny or a lower qualifying average, even if the borrower’s most recent year was strong. Underwriting guidelines found in HUD Handbook 4000.1 generally require that declining income be explained and, in many cases, the lower of the two years (or an even more conservative average) gets used rather than the higher, more recent figure. This is one of the most common surprises for commission-based borrowers who assume their best year automatically becomes their qualifying number.
Understanding this pattern early, ideally before you start shopping for homes in Stafford County, gives you time to gather the right documentation and set realistic expectations about your qualifying income before falling in love with a property that number won’t support.
The Paperwork Underwriters Will Ask For
Commission-based applicants should expect a heavier documentation request than a straight salaried W-2 employee. The specific paperwork depends on how the commission is structured and reported, but a few categories apply almost universally.
- Two years of complete federal tax returns, including all schedules
- Year-to-date pay stubs that clearly break out base pay from commission
- A written Verification of Employment (VOE) completed directly by the employer
- 1099 forms for any contractor-based commission income
- A letter from the employer confirming the likelihood that commission-based pay will continue
The table below breaks down how qualifying methods differ depending on the type of commission arrangement.
| Income Type | Qualifying Method | Documents Required | Notes |
|---|---|---|---|
| Straight commission (W-2) | Two-year average of commission reported on W-2s and tax returns | Two years of tax returns, YTD pay stubs, written VOE | Unreimbursed employee expenses (Schedule 1) may reduce qualifying income |
| Base-plus-commission (W-2) | Base salary counted in full; commission portion averaged over two years | Two years of tax returns, YTD pay stubs, VOE, employer letter | Stronger candidates for approval since base pay provides a income floor |
| 1099 contractor commission | Treated like self-employment; net income after Schedule C deductions is averaged | Two years of tax returns with Schedule C, 1099s, YTD profit-and-loss statement | Business expense deductions can significantly lower qualifying income |
The written VOE and employer letter matter more here than they do for a salaried applicant. A salaried borrower’s future income is fairly predictable from a single pay stub. A commission-based borrower’s future income is inherently a forecast, and underwriters want the employer to confirm, in writing, that the commission structure is ongoing rather than tied to a one-time bonus, a temporary incentive, or a role that’s about to change.
Worked Example: A Garrisonville Real Estate Agent Buying in Embrey Mill
Suppose a real estate agent living in Garrisonville has worked in the same brokerage for three years and wants to purchase a home in Embrey Mill. Her tax returns show commission income of roughly $78,000 in the first year and $86,000 in the most recent year, an average of about $82,000 annually. This figure is illustrative only; actual qualifying income always depends on verified tax returns and current earnings, so buyers should confirm their own numbers against real filings before assuming a specific figure applies to them.
After subtracting unreimbursed business expenses reported on her Schedule C, such as mileage, marketing costs, and MLS dues, her net qualifying income comes in somewhat lower than her gross commission figure. This adjusted number, not the gross commission total, is what underwriting uses to calculate her debt-to-income ratio and determine her approved loan amount.
She’s targeting a $460,000 home in Embrey Mill, a price point that, as of 2026, sits within range of several listings in that community, though buyers should verify current pricing against active MLS data since Stafford County values shift with inventory. With a 10% down payment, she’s financing at 90% loan-to-value, the current compliance-approved maximum for conventional financing. That down payment of $46,000 leaves a loan amount of $414,000.
Using her averaged and adjusted qualifying income, her broker runs her debt-to-income ratio against her existing obligations, car payment, student loans, and minimal revolving credit, to confirm the loan amount fits comfortably within program guidelines. Because her income trend is upward rather than downward, and because two full years of consistent tax filings back up the pattern, her file moves through underwriting without the extra scrutiny that a declining-income borrower might face. The lesson isn’t the specific dollar figures. It’s that the two-year average, adjusted for legitimate business expenses, becomes the real number driving loan approval, not the commission checks she deposited last month.
Mistakes That Delay or Sink Commission-Based Applications
The single most common misconception is assuming a recent raise, a promotion, or a strong final quarter will override the two-year average lenders are required to use. Borrowers sometimes come in with a fantastic last six months and expect that recent performance to carry the application. Underwriting guidelines don’t work that way for variable income, and no amount of recent success substitutes for a documented multi-year pattern.
Another frequent issue is deducting large unreimbursed business expenses on tax returns without realizing it lowers the net income used for qualifying. It makes sense from a tax-planning perspective to maximize deductions and minimize taxable income. But every dollar deducted on a Schedule C or Schedule 1 is a dollar that typically won’t count toward mortgage qualifying income either. Borrowers planning a home purchase in the next one to two years should talk to both their tax preparer and their mortgage broker before filing, so the two goals, tax savings and mortgage qualification, don’t work against each other.
Switching employers or pay structures mid-process is another common derailment. A borrower who accepts a new sales role, even one that pays more, in the middle of a mortgage application can restart the documentation clock before a full history is established at the new position. Lenders generally want to see a track record within a stable structure, and a sudden job change, even an upgrade, can introduce uncertainty that pauses or resets underwriting. If a job change is unavoidable, looping in your broker before making the move gives everyone time to plan around it rather than react to it.
Loan Options for Commission Earners in Stafford County
Commission-based buyers near MCB Quantico, including DoD contractors and civilian personnel whose pay includes performance-based bonuses or commission, often find VA loans a strong fit. VA financing remains available with no down payment for eligible borrowers, and VA cash-out refinances can go up to 100% loan-to-value, giving military-connected commission earners flexibility that conventional financing doesn’t offer at the same terms. Eligibility and documentation requirements for VA loans are outlined by the U.S. Department of Veterans Affairs.
Conventional loans cap at 90% loan-to-value under current compliance guidance, which means commission earners without VA eligibility should plan for a slightly larger down payment than the minimums sometimes advertised elsewhere. For a borrower with variable income, that extra equity cushion also tends to make underwriters more comfortable with the overall risk profile of the file, since it reduces the loan amount relative to documented income.
What matters most for commission earners isn’t finding a single generic loan product, it’s building a personalized mortgage plan around the specific documentation pattern already in place. Duane Buziak has been helping Stafford County families find their new homes since 2014, working as a broker with access to hundreds of wholesale lenders rather than a single set of in-house guidelines. That matters for commission-based borrowers specifically, because different wholesale lenders weigh variable income differently, and a broker can match your documented pattern to the program most likely to approve it rather than forcing your income into a one-size-fits-all box. No-out-of-pocket closing options can also be structured into the loan for borrowers who’d rather preserve cash reserves, an important consideration when income varies month to month.
Commission Income and Mortgage Approval: Quick Answers
Can I get a mortgage on 100% commission income? Yes. Lenders qualify 100% commission income the same way they qualify base-plus-commission income, by averaging two years of documented history. You’ll need tax returns and pay stubs showing the commission breakdown.
How many years of income history do lenders need? Most programs require two years of tax returns showing commission income. In limited cases with a documented one-year history and strong compensating factors, exceptions can be considered, but two years is the standard.
Does a new job offer letter count as income for qualifying? Generally, no, not for commission-based roles. Offer letters work for salaried positions with a guaranteed base, but commission income needs an actual earnings history before it can be counted.
What happens if my commission income declined last year? Underwriters will typically use the lower year’s figure or ask for a written explanation of the decline. A documented downward trend can lower your qualifying income even if your most recent months have improved.
Do unreimbursed business expenses hurt my mortgage approval? Yes. Expenses deducted on Schedule C or Schedule 1 reduce the net income underwriters use to qualify you, even though they also reduce your tax bill.
Do W-2 commission bonuses still require tax returns? Usually yes, if commission makes up a meaningful share of total pay. Underwriters want to see the two-year averaging pattern regardless of whether the income appears on a W-2 or a 1099.
Can commission income qualify for a VA loan near Quantico? Yes. VA loans use the same two-year averaging approach for commission income as conventional loans, and VA cash-out refinances are available up to 100% loan-to-value for eligible borrowers.
How does working with a Stafford-based broker help commission-based borrowers? A broker can compare your documented income pattern against guidelines from hundreds of wholesale lenders, rather than fitting your file into one lender’s rigid criteria, which often matters most for variable-income borrowers.
