"I had a great year. Why isn't the underwriter using it?"
I heard some version of that question all through my decade underwriting loans at two banks, and I still hear it from business owners around Cincinnati. It's a fair question. The answer isn't that the underwriter doubts your business. It's that self-employed income gets read a specific way, and the guidelines spell out exactly how.
Here's what's happening on the other side of the desk. (For the big picture on borrowing when you work for yourself, start with our earlier post, Challenges for Self-Employed Borrowers. This one goes a level deeper, into the analysis an underwriter actually does.)
Who counts as self-employed
Fannie Mae's Selling Guide (B3-3.5-01) treats anyone who owns a quarter or more of a business as self-employed. FHA's handbook (HUD 4000.1, II.A.4.c.x) draws the same line.
That surprises people who pay themselves a W-2 salary from their own S corporation. If you own that much of the company, your file is underwritten as self-employed, W-2 or not, and the underwriter will want to see the business behind the paycheck.
Two years of history, not one
Fannie Mae generally has the lender document a two-year history of self-employment earnings. The underwriter is trying to judge one thing: is this income likely to continue? One year is a small sample.
There are exceptions in both directions:
- A shorter history. Fannie Mae can consider less than two years if your most recent signed returns show a full year from the current business, and you earned at a similar level in the same line of work before. FHA allows one to two years of self-employment when you previously worked in the same or a related field for at least two years.
- A long-running business. If the business has existed for five years and you've owned a quarter or more of it for that whole stretch, Fannie Mae allows the lender to work from one year of personal and business returns, as long as the file supports it.
Either way, expect to provide signed personal returns with every schedule attached, and often the business returns too. IRS transcripts can stand in for the returns themselves.
The trend matters as much as the total
This is the part most business owners don't expect. The underwriter isn't just averaging two numbers. Fannie Mae's guide has the lender "measure year-to-year trends for gross income, expenses, and taxable income for the business," and look at how those figures move over time.
So two files with the same two-year total can read very differently:
- Steady or rising years generally average cleanly.
- A strong year followed by a softer one gets a closer look. The underwriter wants to know why income dipped, and whether it has leveled off.
FHA puts the conservative approach in writing. Under HUD 4000.1, II.A.4.c.x(D), the lender uses the lesser of your two-year average or your most recent year. If last year was the softer year, last year sets the number. And when the decline over that period is large enough, FHA requires the file to be underwritten by hand instead of through its automated system.
USDA's handbook (HB-1-3555, Chapter 9) takes a similar view: sharp increases or decreases in business income can mean the lender asks for more documentation to support the number it uses.
What helps when income dipped: an explanation tied to something specific and finished, like a large client you've since replaced or a one-time equipment purchase, plus a year-to-date profit and loss statement that shows where the business stands now. FHA requires a year-to-date P&L and balance sheet once more than a calendar quarter has passed since your last tax year ended. Schedule C filers don't need the balance sheet.
Net income, with a few add-backs
Underwriters start from what your return shows after expenses, not your sales. This is where tax planning and mortgage planning can pull in different directions. A deduction that lowers your tax bill also lowers the income an underwriter can use.
A few items do get added back, because they're paper expenses or one-time events rather than money leaving the business every year. For Schedule C income, Fannie Mae's Selling Guide (B3-3.6-03) lists depreciation, depletion, business use of a home, amortization and casualty losses. Going the other way, income that isn't recurring gets taken out.
Lenders typically work all of this through Fannie Mae's Cash Flow Analysis (Form 1084) or a tool that follows the same principles, and a written copy of that analysis goes in your file.
What generally doesn't get added back: ordinary write-offs. If you deducted it as a business expense, the underwriter treats it as one.
If you own part of a partnership or S corporation
K-1 income has one more test. Per Fannie Mae (B3-3.6-07), ordinary income from a K-1 can be counted when you have a documented, stable history of receiving cash distributions at that level, or when the lender confirms the business has enough liquidity to support you drawing it. Your share of the profit on paper isn't automatically money the underwriter can count on.
What I tell business owners
- Talk to us before you file, not after. How a return is prepared shapes the income an underwriter can use. Your CPA and your loan officer are answering different questions, and it helps to have both conversations before the return is final.
- Keep business and personal accounts separate. Clean statements make the cash-flow analysis simpler, and they make it easier to document the money you'll bring to closing.
- If income dipped, put the reason in writing now. A clear, specific explanation with documents behind it reads very differently from a vague one written months later.
- Keep a current year-to-date P&L. It's often the first thing an underwriter asks for when the returns tell only part of the story.
- Ask how your loan program reads it. Fannie Mae, FHA, VA and USDA each handle self-employment a little differently, so the same returns can come out differently depending on the program.
If you're self-employed in Greater Cincinnati and thinking about buying in the next year or so, send us your last two returns. We'll read them the way an underwriter would and tell you what we see.
