Commission Income Mortgage Qualification: Why Your No Was Wrong

Commission income mortgage qualification does not require perfectly consistent quarterly earnings, and the lender who told you otherwise may have been applying their own internal policy instead of the actual Fannie Mae Selling Guide. Fannie Mae Selling Guide B3-3.1-04 requires a two-year documented history and a 24-month average calculation. That is the rule. Not a preference. Not a suggestion. The rule. If your lender declined you without citing that specific section, you may be looking at an overlay, not a disqualification, and those are two very different things.

You Are Probably Here Because a Lender Said Your Commission Income Was Too Variable

You handed over your tax returns, your 1099s, and your bank statements. The loan officer looked at your numbers and said something like: your income is too inconsistent, or we cannot rely on commission earnings that fluctuate quarter to quarter. You walked out without a loan and without a real explanation.

Susan was in that exact seat. She spent three years building a marketing consulting business in Atlanta from scratch. Four clients. Performance-based fees. Real contracts, real deposits, real income. Year one was lower because two clients paused campaigns after the holidays. Year two was substantially higher. The first lender saw the dip in quarter one and stopped reading.

They told her: our underwriting team flagged the variability. We cannot use this income.

Susan called me. I asked her one question: did they show you where in the Fannie Mae guidelines it says quarterly variability disqualifies you? She said no. That was the tell.

When a lender says their underwriting team flagged something without citing a specific guideline section, you are probably looking at an overlay. Stay to the end and I will give you the exact words to say to your lender to find out which one it is.

What Fannie Mae Selling Guide B3-3.1-04 Actually Says About Commission Income

Fannie Mae Selling Guide B3-3.1-04 is the governing rule for commission income on conventional loans. Here is what it actually says.

When commission income represents 25% or more of your total annual employment income, Fannie Mae classifies it as variable income. Variable income requires a two-year documented history. The lender calculates it by averaging the commission income received over 24 months. Not the most recent year. Not the highest year. The full 24-month average. The guideline reads: commission income must be averaged over a 24-month period to determine the monthly income amount used in qualifying the borrower.

The rule does not say income has to be growing. It does not say it has to be identical quarter to quarter. It says document two years and average them. If year one was lower and year two was higher, the lender averages both. If both years were strong, the average reflects that. The income has to be documentable, not uniform.

B3-3.1-04 does address declining income. If income is trending downward year over year, the lender must use the lower year or the most recent 12-month figure, whichever is less. If income is stable or increasing, the 24-month average applies. That is a calculation method, not a denial trigger.

The guideline also does not limit commission income to a single employer or client. Susan had four clients. B3-3.1-04 requires documentation of the income, not uniformity of the source.

Here is what the guideline actually requires you to provide: federal tax returns for the two most recent tax years including all schedules, W-2s or 1099s for the same two-year period, and a year-to-date profit and loss statement if you earn commissions through a business structure.

Now here is the part most loan officers skip. Fannie Mae sets the minimum standard. Individual lenders are allowed to add their own requirements on top of that standard. Those additions are called overlays. An overlay is not a Fannie Mae rule. It is a rule the lender invented for their own risk management, their own operational capacity, or sometimes because no one updated their internal policy in five years.

Common commission income overlays include requiring two years of increasing income rather than two years of documented income, requiring that no single quarter fall below a set threshold, and requiring that all commission income come from one employer rather than multiple clients. None of those requirements appear in B3-3.1-04. All of them are overlays. Overlays are legal. Lenders are allowed to have them. But you have the right to know whether a decline is based on the actual Fannie Mae guideline or the lender's internal policy, because those are not the same thing, and a different lender may say yes.

Here Is What I Did to Close Susan's Loan

Step one: I pulled up Fannie Mae Selling Guide B3-3.1-04 and read the commission income section line by line. Not a training slide. The actual text.

Step two: I asked Susan to send me her last two years of federal tax returns, both years of 1099s from her marketing clients, and a year-to-date profit and loss statement for the current calendar year.

Step three: I ran the 24-month average calculation before submitting anything. Year one commission plus year two commission divided by 24. The monthly figure was strong enough to support the loan amount she needed.

Step four: I wrote a loan summary memo to the underwriter citing B3-3.1-04 directly, explaining the income calculation methodology, and noting that the income trend was positive from year one to year two.

Step five: I submitted to a lender whose overlay set did not include a requirement for consistent quarterly income. They ran the file against the actual Fannie Mae guideline. Susan and her husband closed on their home in Atlanta. The income the first lender called too variable was the same income that qualified her under the rule the first lender never fully read.

I read the actual government manuals. Fannie Mae Selling Guide, HUD 4000.1, USDA HB-1-3555, VA Pamphlet 26-7. As a licensed broker, I am not locked into one lender's overlay set. I shop your file to the lender whose guidelines fit your documentation. That is the operational difference between a broker and a bank.

Here Is What I Promised You

Under Fannie Mae Selling Guide B3-3.1-04, commission income exceeding 25% of your total income is treated as variable income and requires a two-year documented history. The lender averages that income over 24 months to determine your monthly qualifying figure.

Before you apply, gather these documents: federal tax returns for the two most recent tax years including all schedules, 1099s from every commission-paying client or employer for the same two years, a year-to-date profit and loss statement prepared or signed by a licensed CPA, and bank statements for the most recent two to three months showing commission deposits.

Here is the exact question to ask any lender who declines you: is this decline based on Fannie Mae Selling Guide B3-3.1-04, or is it based on your internal overlay policy? Can you show me where in the Fannie Mae guideline my documentation fails the two-year averaging requirement? If they cannot answer that with a specific guideline citation, you are looking at an overlay decline. Find a broker who works closer to the actual rule.
