Buying a Home When You're Self-Employed: How Write-Offs Affect Your Buying Power
Hi, I'm Alex Hernandez, a mortgage loan officer with Guild Mortgage in St. George, Utah. I work with a lot of self-employed buyers: contractors, real estate agents, business owners, gig workers, and side-hustlers who went full time. Many of them are doing great financially, but they're surprised when the amount they qualify for is lower than expected. The reason is almost always the same: tax write-offs. In this post I'll explain how lenders look at self-employment income, why deductions shrink your buying power, and what you can do about it.
Who Counts as Self-Employed?
For mortgage purposes, you're generally considered self-employed if you own 25% or more of a business, or if you're paid on a 1099 instead of a W-2. That includes sole proprietors, LLC members, partners, and S-corp or C-corp owners. Fannie Mae's Selling Guide on self-employed borrowers lays out how lenders document and analyze this income on conventional loans.
How Lenders Calculate Self-Employed Income
With a W-2 job, I can mostly look at your pay stubs. With self-employment, I start with your tax returns, because that's the income the IRS sees. Typically that means:
- Personal tax returns, including Schedule C if you're a sole proprietor.
- Business tax returns (1065 or 1120S with K-1s, or 1120) if you own a partnership or corporation.
- Often two years of returns, though some files qualify with one year depending on the loan program and your history.
- Sometimes a year-to-date profit and loss statement or business bank statements.
From there, I calculate your qualifying income. When two years are used, it's often averaged, and if income dropped from one year to the next, the lower or declining figure usually gets more weight. Lenders also want to see that the business is stable and likely to continue.
Why Write-Offs Reduce Your Buying Power
This is the part that catches people off guard. Your accountant's job is to legally lower your taxable income. My job is to qualify you based on documented income. Those two goals can pull in opposite directions.
A simple illustration
Let's say your business brings in $150,000 in gross revenue. After expenses like supplies, a truck, a home office, meals, and phone, your Schedule C shows $60,000 in net profit. For qualifying, I generally start from that $60,000, not the $150,000. That's a big difference in what you can afford. (These are illustrative numbers, not a quote or a prediction for any specific borrower.)
Some deductions get added back
The good news: certain expenses are "non-cash" or one-time, and guidelines allow lenders to add them back to your income. Common examples include:
- Depreciation and depletion
- Amortization and casualty losses
- Business use of your home, in some cases
- Certain documented one-time, non-recurring losses
Everyday expenses like supplies, fuel, and advertising generally aren't added back, since they're real ongoing costs of running the business. Exactly what can be added back depends on the program and how the expense shows up on your returns.
Your Debt-to-Income Ratio Still Matters
Once I know your qualifying income, it goes into your debt-to-income ratio (DTI), just like any other buyer. If you have business debts in your personal name, like a truck loan, they may count against you unless the business pays them and that's documented. I go over DTI and the rest of the lender checklist in prequalified vs preapproved: what a lender actually looks at.
Strategies for Self-Employed Buyers
Plan a year or two ahead
If buying a home is on your horizon, talk to me and your tax professional before you file. Sometimes it's worth claiming fewer deductions for a year or two to show more income. That's a tradeoff between taxes and buying power, and only you and your tax pro can decide what makes sense. I'm not a tax advisor, but I can show you what different income levels would qualify for.
Keep business and personal finances separate
Separate bank accounts make it much easier to document income and to show which debts the business pays.
Watch for big year-over-year drops
A decline in income usually needs an explanation and can limit what I'm able to use. Steady or rising income is easiest to work with.
Keep your returns and P&L clean and filed
Unfiled returns or extensions can delay things. Have your most recent returns filed and ready.
Consider all your options
FHA, conventional, and VA loans all allow self-employed borrowers when the income is documented. A low down payment option could also help, which I cover in you probably don't need 20% down in Utah. If you're buying an investment property, some investors use other loan types; see my general explainer on what a DSCR loan is.
What to Gather Before We Talk
- Your last two years of personal tax returns, all schedules included.
- Business returns and K-1s if you own a partnership or corporation.
- A year-to-date profit and loss statement, if available.
- Two months of personal (and possibly business) bank statements.
- Proof the business is active, like a business license or CPA letter, if requested.
Frequently Asked Questions
Can I get a mortgage with only one year of self-employment?
Sometimes. Some guidelines allow it when you have a strong history in the same line of work beforehand. It depends on the program and your full file, so let's review it together.
Do lenders use my gross revenue?
Generally no. Qualifying income usually starts from your net income on your tax returns, with certain non-cash items like depreciation added back.
Should I stop taking write-offs to buy a house?
That's a decision for you and your tax professional. I can show you how different income levels change what you qualify for, so you can make an informed choice.
Are 1099 contractors treated as self-employed?
Usually, yes. 1099 income is typically documented with tax returns, much like other self-employment income.
Let's Look at Your Numbers
Self-employed buyers often have more options than they think. The key is understanding how your returns read to an underwriter. Send me your info and I'll review it personally and tell you where you stand.
