How to Buy a House as an Independent Contractor

Buying a house as an independent contractor works through the same mortgage programs available to salaried employees, but lenders qualify you on the net profit shown on two years of tax returns rather than gross revenue or pay stubs. That single difference drives everything else: the documents you gather, the deductions you claim in the years before you apply, and often the loan program that fits you best. The write-offs that lower your tax bill also lower the mortgage you can qualify for, and most self-employed borrowers don’t realize that until an underwriter runs the numbers.

How Lenders Calculate Your Qualifying Income

A W-2 employee earning $100,000 qualifies on that full amount. A sole proprietor who collects $100,000 in revenue and claims $40,000 in deductions qualifies on $60,000 of net profit from Schedule C. Lenders pull that figure directly from your returns, and it isn’t negotiable.

The standard method averages two years. Net profit of $55,000 one year and $65,000 the next produces $60,000 in qualifying income. When income trends upward, some lenders use the lower year or the average depending on the program. When it trends downward, the picture gets worse. FHA guidelines require a downgrade to manual underwriting, with stricter debt-to-income limits, when income declines more than 20 percent over the analysis period.¹ Fannie Mae doesn’t publish a specific cutoff but requires lenders to measure year-to-year trends in gross income, expenses, and taxable income and decide whether the trajectory supports repayment.²

Deductions That Get Added Back

Not every deduction hurts you. Depreciation, depletion, and amortization are non-cash expenses, so lenders add them back to your net profit. If your Schedule C shows $60,000 in net profit and $12,000 in depreciation, your qualifying income rises to $72,000. The same add-back applies to depreciation reported on Form 1120-S for S-corporations or Form 1065 for partnerships.

Timing matters. A large Section 179 write-off, say $80,000 of equipment expensed in one year rather than depreciated over five, sinks your net profit for that year. Part gets added back, but not all. If you know you’ll be applying for a mortgage within a year or two, spreading deductions across multiple returns produces a stronger income trend on paper.

How Business Structure Changes the Math

Sole proprietors are the simplest case: qualifying income is Schedule C net profit plus add-backs. S-corporation owners usually pay themselves a W-2 salary and take K-1 distributions on top of it. Lenders count both, but they need to see that the K-1 income was actually distributed in cash, not just allocated on paper, and that the business has enough liquidity to keep making those distributions.³

Partnership income works the same way through the K-1 from Form 1065. Fannie Mae treats you as self-employed once you own 25 percent or more of a business.⁴ Below that threshold, your share may be treated as investment income instead, which changes the documentation.

What Lenders Require Before They’ll Approve You

Two Years of Self-Employment

Conventional and FHA lenders both look for at least two years of continuous self-employment.¹ With one to two years of history, FHA may still count your income if you spent at least two prior years as an employee in the same field or a closely related one, and some conventional lenders apply a similar exception. Under a year of self-employment and most programs won’t count the income at all.

Credit Score

Conventional loans run through Fannie Mae’s automated underwriting have no hard minimum score. Manually underwritten conventional loans require 620 for a fixed rate and 640 for an adjustable rate.⁵ FHA is more flexible: 580 qualifies you for the 3.5 percent minimum down payment, and scores from 500 to 579 require 10 percent down. Because lenders treat irregular income as added risk, a strong score works harder for a self-employed borrower than it does for a W-2 applicant.

Debt-to-Income Ratio

Your debt-to-income ratio measures monthly debt payments, including the new mortgage, against your monthly qualifying income. Conventional loans generally cap this at 50 percent, with under 43 percent preferred.⁶ FHA sets standard limits at 31 percent for the mortgage payment and 43 percent for total debt, though borrowers scoring 580 or higher can reach 37/47 with one compensating factor and 40/50 with two.⁷ Because your qualifying income is net profit rather than gross revenue, you’ll hit these caps sooner than you’d expect.

Business Verification

Lenders confirm the business is still operating within 120 calendar days before closing. They may contact a CPA, a licensing bureau, or a regulatory agency, or verify a phone listing and address through a directory or the internet.⁸ Keep your licenses current and your business listed online so this step doesn’t stall the file.

Documents to Gather

Assembling everything before you apply speeds the process and cuts down on the back-and-forth that usually delays self-employed files.

You need two years of complete personal federal tax returns with every schedule. Sole proprietors submit Form 1040 with Schedule C. S-corporation owners add two years of Form 1120-S and the associated Schedule K-1. Partnerships add Form 1065 with the K-1.³ Collect the 1099-NEC forms your clients issued so the underwriter can match reported income to your returns.

You’ll sign Form 4506-C authorizing the lender to pull your IRS transcripts. Fannie Mae requires this from every borrower whose income is used to qualify.⁹ Any mismatch between what you filed and what the IRS shows will end the deal.

Expect requests for three to six months of personal and business bank statements. Deposits should line up with the income on your returns. Large or irregular deposits get flagged, so be ready to explain a $15,000 wire that doesn’t look like a typical client payment. Undocumented gifts or loans can sink an approval.

A year-to-date profit and loss statement isn’t always mandatory on the conventional side. Fannie Mae lenders may still ask for one when they need extra support for income stability, particularly if your application is dated more than 120 days after your business’s tax year ends.¹⁰ FHA lenders generally require a year-to-date profit and loss statement together with a balance sheet.¹ The statement can be borrower-prepared or audited.

Round the package out with a current business license, articles of incorporation, or a CPA letter confirming the business exists and is active. CPAs are prohibited from commenting on your solvency, so a lender asking for a letter about “financial stability” may need to adjust the language.

What to Do in the Year or Two Before You Apply

The best time to start preparing is 12 to 24 months out. A few decisions in that window shape what you’ll qualify for.

Be intentional about deductions. Every dollar on Schedule C is a dollar subtracted from your qualifying income. Legitimate expenses should still be claimed, but the timing is yours to control. Deferring a large equipment purchase or spreading Section 179 across several years can add real borrowing power. Run the tradeoff between tax savings and mortgage qualification past your CPA before you start house hunting.

Separate your business and personal accounts if they’re mixed. Underwriters trace cash flow much faster when client deposits land in a business account and personal spending comes out of a personal one.

Build reserves. Lenders often want to see several months of mortgage payments still sitting in the bank after your down payment and closing costs are paid. Two to six months of reserves is a common range, varying with the loan program, your credit score, and your down payment. Savings, retirement accounts, and investment accounts all count.

Pay down debt. Because your qualifying income is lower than your gross revenue, your DTI is more sensitive to outstanding balances than a W-2 borrower’s would be. Eliminating a $400 monthly car payment frees up the same qualifying room as earning $4,800 more per year.

Loan Programs That Fit an Independent Contractor

Conventional Loans

Loans backed by Fannie Mae and Freddie Mac are the most common path when your tax returns support the income you need. First-time buyers can put as little as 3 percent down through programs like HomeReady and the 97 percent loan-to-value option.¹¹ Repeat buyers generally need 5 percent. Below 20 percent down, you pay private mortgage insurance until you build enough equity to remove it.¹² Conventional loans give you the best rates when your credit and income documentation are strong.

FHA Loans

FHA loans, insured by the Federal Housing Administration, fit contractors with lower credit or thinner savings. The minimum down payment is 3.5 percent with a 580 score.¹³ FHA allows higher DTI ratios than conventional, with 580-plus borrowers reaching as high as 50 percent with compensating factors.⁷ The tradeoff is mortgage insurance for the life of the loan if you put less than 10 percent down, plus slightly more rigid self-employment documentation.

Bank Statement Loans

When aggressive tax deductions push your net profit far below your actual cash flow, a bank statement loan offers another route. These non-QM products calculate your income by averaging deposits over 12 to 24 months and skip the tax returns. The catch is cost: down payments typically start at 10 percent and rates run noticeably above conventional and FHA. Worth considering when your returns understate your real income; not the first choice when a traditional program will work.

Adding a Non-Occupant Co-Borrower

If your income alone falls short, a family member with W-2 income can co-sign without moving in. Fannie Mae permits non-occupant co-borrowers on conventional loans, though the maximum loan-to-value ratio may be slightly lower than for occupant-only transactions.¹⁴ The co-borrower carries full legal responsibility for the mortgage, so treat the decision accordingly.

What Changes at Application and Underwriting

Once your finances are in shape and you’ve picked a program, the sequence looks like any other purchase, with a few extra beats.

Get pre-approved before you make offers. Pre-approval takes longer for a contractor because the lender has to review your returns and calculate qualifying income before issuing the letter. Doing this early surfaces documentation problems while you still have time to fix them, and in competitive markets sellers often won’t consider an offer without one.

Underwriting takes longer for self-employed files because the income calculation involves judgment calls. Expect a conditional approval first, with follow-up requests for an updated bank statement, a written explanation of an unusual expense, or a CPA letter. Answer quickly. Each day you sit on a condition pushes your closing date.

Before closing, the lender verifies your business is still active within that 120-day window.⁸ Keep the phone answered and the license visible until you have keys in hand.
