Self-employed mortgage guide: how to actually qualify
Your business is doing well, revenue is strong, money is coming in — and the lender tells you that you qualify for far less than you expected. It almost always comes down to one thing: how underwriters read self-employed income.
What underwriters use
Net
Taxable income, not gross revenue
Standard income averaging
24 mo
One year possible after five in business
Non-QM down payment
20%
On every alternative-documentation loan
This comes from a session with Wes Friedman, our mortgage advisor, who works with self-employed borrowers constantly. There are more misconceptions on this topic than almost any other in lending.
Underwriters don't look at what your business made
Underwriters calculate net taxable income. Every deduction you take to reduce your tax bill also reduces what you can borrow against.
And $90,000 is a modest example. Plenty of business owners grossing $300,000 write off $150,000 to $200,000 — excellent tax strategy, and it can leave a genuinely profitable business looking like a low income on paper.
The tension is real and there's no way around it. What reduces your taxes reduces your borrowing power. The question is how you manage the trade-off.
Two years, and direction matters enormously
Underwriters want to see consistency and stability, so they typically go back 24 months and average.
| Year one | Year two | Qualifying income | |
|---|---|---|---|
| Rising income | $80,000 | $150,000 | $115,000 (averaged) |
| Declining income | $150,000 | $80,000 | $80,000 (most recent only) |
Rising income gets averaged, which pulls your qualifying figure down from the strong year but up from the weak one.
Declining income is treated very differently. The underwriter discards the higher earlier year entirely and uses only the most recent twelve months. You get no credit for the good year.
The logic is that a downward trend line suggests the future looks more like the recent year than the older one. Harsh, but consistent.
The five-year exception
If you can show you've been incorporated or filed self-employed taxes for five years in the same line of work — a CPA letter can verify this — the lender may ask for only your most recent return rather than two.
That's a meaningful advantage when income is rising. In the example above, five years of history means qualifying on the $150,000 alone rather than the $115,000 average.
Two things worth understanding. It doesn't rescue declining income — you're still limited to the most recent year either way. And it's less paperwork, which matters more than it sounds if your returns are complex.
Sometimes less is more in underwriting. A single strong return can qualify you for more than two returns averaged together.
W-2 salary and K-1 distributions
If you're set up as an S corp and pay yourself a salary, underwriters look at consistency across 24 months. You can't raise your own salary, produce a fresh pay stub showing $10,000 a month against a $5,000 average, and expect it to count.
That's the obvious vulnerability of self-employment — you can pay yourself anything — so lenders assume nothing about a sudden increase.
K-1 distributions are treated the same way as salary. Both get averaged over 24 months, and both are subject to the declining-income rule. If either falls in the most recent year, the earlier year is discarded.
Company distributions are different
A company distribution — retained earnings paid out to yourself — is not the same as a K-1. The K-1 passes through to your personal return. A distribution of retained earnings is generally not taxable to you, because the company has already paid tax on it.
You can absolutely use it as a down payment. Using it as income is harder and requires more: a fully ratified profit and loss statement from a licensed CPA, plus a liquidity test on the business to confirm that removing those funds won't affect day-to-day operations.
Lenders generally avoid using distribution income where possible, because retained earnings depend on company performance and may not repeat.
Some deductions get added back to your income
Not every write-off reduces your qualifying power. Three common ones get added straight back:
- Depreciation — a paper expense where no money actually left your account
- Business mileage on a vehicle used for work
- Office expenses, including a home office
Depreciation is the big one. It's a phantom write-off — you deduct the declining value of an asset without spending anything that year — so lenders treat it as income.
| No depreciation | With $25,000 depreciation | |
|---|---|---|
| Net income on return | $80,000 | $80,000 |
| Add back | — | +$25,000 |
| Qualifying income | $80,000 | $105,000 |
| Monthly | $6,667 | $8,750 |
An extra $2,083 a month of qualifying income from a deduction that cost you nothing in cash. Two business owners both showing $80,000 in net profit will not qualify for the same loan if one took depreciation and the other didn't.
Wes has closed a loan for a borrower showing negative net income of more than $100,000 who had $350,000 in depreciation — and ended up with positive qualifying income.
One caution on accelerated depreciation
Plenty of people buying short-term rentals now take large accelerated depreciation in year one. It's legal and often smart. But if you exhaust it in a single year and then need two years of returns averaged, the following year shows nothing and the average suffers.
Spreading it across years usually serves qualification better. Worth discussing with your CPA and your lender together rather than separately.
Tax extensions, used deliberately
Most self-employed people extend their filing to mid-October anyway. That creates a genuine planning window.
If your most recent year was weak: don't file it yet. Apply for the mortgage using the two prior years, when income was stronger.
If you're newer in business: sit down before you file and work out what level of write-offs still leaves you able to qualify. You can decide how much depreciation to take and where to hold back, so the averages support the loan you want.
Either direction, the point is that filing and financing should be planned together rather than discovered in sequence.
Conventional, FHA and VA
| Minimum score | Minimum down | Tax returns needed | |
|---|---|---|---|
| Conventional | 620 | 3% | One year possible |
| FHA | ~580 | 3.5% | Two years required |
| VA | ~580 | 0% | Two years required |
The key difference for self-employed borrowers: government-backed loans do not permit one-year tax filing. If you're using FHA or VA, expect 24-month averaging regardless of how long you've been in business. Conventional is the flexible one.
Note also that the 3% and 5% down conventional programs are owner-occupied only. Investment property requires 20% down, second homes a minimum of 10%.
Non-QM loans
Every conventional and government loan requires the lender to establish your ability to repay, which means W-2s, tax returns and standard income documents.
Non-QM loans don't. They use alternative documentation, and they exist largely for self-employed borrowers.
Bank statement loans
The lender takes 12 or 24 months of personal or business bank statements and averages your gross deposits. You complete a questionnaire declaring your fixed monthly operating expenses — office costs, salaries, recurring items — which becomes your expense ratio. Deposits minus that ratio is your qualifying income.
On $100,000 a month in average deposits with a $10,000 expense ratio, qualifying income is $90,000 a month — even if $89,000 of it goes back out on variable costs, cost of goods or acquisitions.
They don't critique your write-offs. For business owners who deduct heavily, that's the entire appeal.
Deposits do need to be consistent. Two $100,000 deposits a year with nothing in between won't work — they want to see a regular flow that matches the business you've described.
It also works well for heavily tipped workers, which matters in this city. Tips often don't flow through tax filings in a way that supports traditional qualification.
1099-only loans
Qualify on your 1099 forms alone, without tax returns. Works for independent contractors, real estate agents, rideshare drivers, and investors receiving year-end 1099s from brokerages.
One year of 1099s is possible but carries a higher rate. Two years gives the underwriter more stability to assess and gets you better pricing.
DSCR loans
For investment property, qualifying on the property's rent rather than your income. If market rent is at least 75% of the mortgage payment and you have 20% down, you qualify. Minimum score 640, with better rates at higher scores.
On a $2,000 monthly payment, rent of $1,500 clears it. Full detail in our DSCR loan guide.
What non-QM costs you
20% down, on all of them. That's the main constraint. You can't do a bank statement or 1099-only loan with 3.5% down.
Roughly half a point higher on rate, on average. Not always — Wes recently saw a DSCR loan price better than a Fannie Mae loan for a borrower with an 800 credit score and substantial assets. But plan for slightly higher.
Set against that, the larger down payment means a smaller loan, so the payment comparison is closer than the rate comparison suggests.
And there's a cost that doesn't appear in any rate sheet. If you own several businesses and a portfolio of rentals, a traditional application means every mortgage statement, HOA statement and insurance policy on every property. It genuinely becomes a part-time job. Half a point to avoid that is a reasonable trade for a lot of people.
One thing worth noting: if you have several 1099s and you don't have heavy expenses, file the returns. You'll qualify traditionally, and you'll put less money down.
Self-employed mortgage FAQ
Why can't I qualify for more when my business makes good money?
Because underwriters use net taxable income rather than gross revenue. Every deduction that reduces your tax bill also reduces the income you can borrow against. A business grossing $300,000 with $90,000 in expenses qualifies on $210,000 — and many owners at that level write off $150,000 to $200,000, which leaves a profitable business looking like a modest income on paper.
How do lenders average self-employed income?
Typically over 24 months. If income rose from $80,000 to $150,000, they average the two for $115,000. If it declined from $150,000 to $80,000, they discard the earlier higher year entirely and use only the most recent twelve months, so you get no credit for the strong year. Direction of travel matters as much as the amounts.
Can I qualify with only one year of tax returns if self-employed?
On a conventional loan, yes, if you can show five years of self-employment in the same line of work — either incorporation records or five years of filings, which a CPA letter can verify. That lets you qualify on your most recent return alone, which helps considerably if income is rising. Government-backed FHA and VA loans do not permit one-year filing regardless of history.
Does depreciation help or hurt when applying for a mortgage?
It helps. Depreciation is a paper expense where no cash left your account, so lenders add it back to qualifying income. A borrower showing $80,000 net income with $25,000 of depreciation qualifies on $105,000 — $8,750 a month rather than $6,667. Business mileage and office expenses are also commonly added back. Two owners both showing $80,000 in profit will not qualify equally if only one took depreciation.
What is a bank statement loan?
A non-QM loan that qualifies you on deposits rather than tax returns. The lender averages 12 or 24 months of personal or business bank statements and subtracts an expense ratio based on your declared fixed operating costs. On $100,000 in average monthly deposits with a $10,000 expense ratio, qualifying income is $90,000 a month regardless of variable spending. Deposits must be consistent, and 20% down is required.
Do non-QM loans have much higher interest rates?
Around half a point higher on average, and occasionally better — a DSCR loan recently priced below a comparable Fannie Mae loan for a borrower with excellent credit and substantial assets. All non-QM loans require at least 20% down, which means a smaller loan amount, so the payment difference is narrower than the rate difference implies.
Can I use a tax extension to help qualify for a mortgage?
Yes, and many self-employed borrowers do. Extending to October means that if your most recent year was weak, you can apply using the two prior stronger years before filing. It also works in reverse: if you're newer in business, you can plan your write-offs before filing so the averages support the loan you want. Filing and financing are worth planning together.
Structure it before you shop
Qualifying while self-employed is mostly about how your income appears on paper — the way you file, the deductions you use, and the loan program you choose. Sorted out in advance, it opens options most people don't know they have.
Worth doing before you start looking at houses, not after.
