How to Qualify for a Mortgage When You're Self-Employed

Readiness Checklist

Each item below is something you can verify or produce before you apply.

• Documented ownership interest of 25% or more in the business whose income you want to use (Fannie Mae, 2023-12-13; New American Funding, undated).
• Two years of signed, complete personal federal tax returns with all schedules, if you are applying for FHA (FHA.com, undated; New American Funding, undated).
• Business returns matching your entity type — partnership Form 1065, corporate Form 1120 or S-corp Form 1120S — with Schedule K-1(s) or Form 1125-E where the entity requires them (Fannie Mae, undated; Freddie Mac, undated).
• One IRS Form 4506-C signed for your personal transcripts and a separate Form 4506-C signed for business transcripts; the form covers up to four years or tax periods and stays valid 120 days after completion (Fannie Mae, undated).
• If your self-employment history is under two years: most recent signed personal and business returns showing a full 12 months of income from the current business, plus documented prior experience in the same field (Fannie Mae, 2023-12-13).
• If every self-employed business has existed five years and you have held 25% or greater ownership for the last five consecutive years: one year of personal and business returns may be accepted (Innovative Mortgage Brokers, undated). Freddie Mac's version of this is five or more years in business for one year of returns, and two years of returns if the business is under five years old (NewRez Correspondent citing a Freddie Mac table, 2017-03-06).
• A year-to-date profit and loss statement for the current year (FHA Mortgage Source, undated).
• Your net income after expenses and deductions calculated from the bottom line of Schedule C or your K-1 — not gross revenue or total 1099s (Mortgages by Channing, undated).
• Total monthly debt payments plus the proposed housing payment at or below 43% of gross monthly income, the threshold used by the original General QM standard (Consumer Financial Protection Bureau, 2013-10).
• For FHA specifically, housing payment alone at or below 31% of gross monthly income (Rize Mortgage, undated).
• 12 to 24 months of business or personal bank statements, if you intend to apply through a bank statement program instead (Truss Financial Group, undated).
• Written explanation and paper trail for every large or non-payroll deposit in the statements you hand over.

What Lenders Actually Check

A lender verifies three things about you: identity of income, stability of income, and capacity to repay.

Identity. Your ownership percentage sets the rules. At 25% or more in a business, partnership, S-corporation or corporation, you are self-employed and the file is built from tax returns, Schedule K-1(s) or Form 1125-E rather than pay stubs (Freddie Mac, undated). Lenders confirm what you filed by pulling IRS transcripts with Form 4506-C — one for personal returns and a separate one for business returns (Fannie Mae, undated).

Stability. Fannie Mae generally requires a two-year history of prior earnings (Fannie Mae, 2023-12-13). Freddie Mac allows a shorter self-employment history if you have a combined two-year record of the current self-employment plus a prior job in the same or similar occupation, and sets qualifying income at the lesser of the two stable monthly income figures (PennyMac Correspondent Group citing Freddie Mac Selling Guide Bulletin 2024-10, 2024). If your income fell year over year, underwriters use the lower of the two years (Truss Financial Group, undated).

Capacity. Qualifying income is net income after expenses and deductions as reported on your returns (Mortgages by Channing, undated). For FHA, lenders average the last two years of 1099 income alongside a year-to-date profit and loss statement, and they expect bank deposits to track reasonably close to reported 1099 income (FHA Mortgage Source, undated). That monthly figure becomes the denominator in the DTI calculation: proposed housing payment divided by gross monthly income for the front-end ratio, and all monthly debts including the new mortgage for the back-end ratio.

Thresholds by program: FHA guidelines put the housing ratio at no more than 31% and total DTI ideally under 43% (Rize Mortgage, undated), with a 580 score needed for maximum financing at 3.5% down and 500–579 generally limited to 90% LTV (Lower.com, undated). Manually underwritten Fannie Mae fixed-rate conventional loans generally use a 620 minimum credit score, and manually underwritten ARMs 640 (Lower.com, undated); for new loan case files run through Desktop Underwriter created on or after 16 November 2025, Fannie Mae removed its 620 minimum representative score requirement (National Mortgage Professional, 2025-11). On the DTI side, a loan with a DTI of 43% or less met the original General QM standard (Consumer Financial Protection Bureau, 2013-10), though the CFPB's General QM Final Rule replaced that hard DTI limit with a pricing-based test tied to rate spread (Morgan Lewis, 2020-12). Lenders can and do impose stricter overlays than the agency minimums.

Mortgage insurance differs by product and belongs in your comparison: FHA loans carry both an upfront and an annual mortgage insurance premium regardless of down payment; conventional loans require private mortgage insurance when your down payment is below the lender's threshold, removable later under investor and servicer rules; bank statement programs are non-agency products priced by the individual lender, so ask in writing whether mortgage insurance applies. Bank statement loans themselves use 12 to 24 months of business or personal statements and approve income on actual deposits rather than tax returns, with no W-2s or pay stubs (Truss Financial Group, undated) — which suits a borrower with heavy legitimate write-offs and strong deposits, not a borrower who simply lacks records.

Common Disqualifiers

• Ownership below 25%. FHA requires a minimum 25% interest to qualify using self-employment income (New American Funding, undated). Below that, the income typically cannot be counted as self-employment income at all.
• Aggressive write-offs. Qualifying income is the net figure from Schedule C or your K-1 (Mortgages by Channing, undated), so deductions that cut net income push your DTI above the 43% General QM threshold (Consumer Financial Protection Bureau, 2013-10) and shrink the loan amount.
• Declining year-over-year income. The lender uses the lower of the two years' net income (Truss Financial Group, undated), which can reduce approved loan size or sink the ratio.
• Under two years self-employed with no related background. Without a full 12 months on the most recent returns plus documented prior experience in the same field, Fannie Mae generally will not accept the income (Fannie Mae, 2023-12-13).
• Incomplete tax returns. FHA requires complete individual federal returns for the most recent two years including all schedules (FHA.com, undated); a missing schedule suspends the file until it is produced.
• Stale or missing 4506-C. The form is valid 120 days after completion and a separate one is needed for business returns such as Form 1065, 1120 or 1120S (Fannie Mae, undated) — a lapse means re-signing and re-ordering transcripts before closing.
• Deposits that do not match reported income. On FHA files, bank statement income should track relatively closely to reported 1099 income (FHA Mortgage Source, undated); large unexplained deposits get excluded from qualifying income or trigger a source-of-funds condition.
• Credit score under the program floor. A 500–579 FHA score is generally limited to 90% LTV, requiring at least 10% down (Lower.com, undated), and a manually underwritten conventional fixed-rate file generally needs 620, or 640 for an ARM (Lower.com, undated).
