12-Month Bank Statement Loan Requirements Versus 1099-Only Loans

The Quick Read: A 12-month bank statement loan is reviewed around the deposits in your accounts over one year, while a 1099-only loan is reviewed around the gross income printed on your 1099 forms. Both are alternative-documentation programs, and both still require the lender to verify what you earn. The right choice depends on how your income arrives, not on which product sounds easier.

• Bank statement loans start from deposits (business or personal), averaged over 12 months, with lender-specific expense factors.
• 1099-only loans start from the 1099 forms, so they suit people paid by a small number of clients who issue those forms.
• On a primary residence, select lenders in Lendmire’s wholesale network go up to 90% LTV on a purchase or rate-term refinance with bank statement documentation, with the strongest files earning the top of that range.
• Owner-occupied cash-out is lower: up to 80% LTV on a primary residence and up to 75% on a second home.
• Both are personal-income products. A rental purchase usually moves to DSCR, which is reviewed on the property’s income.

Here is the honest answer on who each is for. Bank statements fit owners with several clients, revenue that runs through an account, or heavy write-offs that shrink taxable income. A 1099-only loan fits the contractor or commission earner whose pay is already documented on a clean set of forms. Terms vary by lender, and every file is underwritten individually.

Side-by-Side

This table shows how the two paths differ on the file itself. The 1099-only column reflects published industry norms with qualifiers. The bank statement column reflects what select lenders in Lendmire’s network use, subject to lender guidelines.

Loan sizes on the bank statement side run roughly $125,000 to $3,500,000. For the full picture of how alternative documentation fits next to investor loans, see Lendmire’s complete DSCR loans guide.

Key Terms Defined

Expense factor: A percentage the lender subtracts from business deposits to estimate what is left after operating costs.

Non-QM: A mortgage that falls outside the standard qualified-mortgage box, often because income is documented in a nonstandard way.

LTV (loan-to-value): The loan amount as a share of the property’s value or price.

Gross income: What you earned before expenses, which is what a 1099 form generally reports.

Reserves: Liquid savings a lender wants you to hold after closing, counted in months of the housing payment.

How Each Path Calculates Income

A bank statement file starts with 12 months of statements. The underwriter screens out deposits that are not income, such as transfers between your own accounts, refunds, and one-off items. HousingWire’s non-QM guide describes bank statement loans as verifying income with 12 to 24 months of personal or business statements, with an expense factor that may apply.

Next, the eligible deposits are averaged by month. On business accounts, the lender applies an expense factor. Many guidelines use a flat percentage by business type, and a letter from a CPA, enrolled agent, or tax preparer can sometimes document a lower expense ratio. The factor is set by the program, not by you. Personal accounts are treated differently from program to program: some credit deposits directly, and others still apply a factor. If you own part of the business, the credit usually follows your ownership share.

A 1099 file runs on a different logic. The same HousingWire guide says these loans verify income with one to two years of IRS 1099 forms, depending on the program. The lender looks at the gross amounts reported, not each deposit. Supporting items often include ID, a check on work history, and sometimes a year-to-date profit-and-loss statement. How much of the gross figure gets credited is program-specific, so ask before assuming.

Neither path is a loophole. The lender must still verify the income it relies on using reasonably reliable third-party records, which is the standard laid out in the CFPB’s small-entity compliance guide for ability-to-repay rules. That guide also lists self-employment as a type of income a lender may consider.

When the 12-Month Bank Statement Loan Is the Better Fit

It is the better fit when your income shows up in deposits more cleanly than it shows up on forms. Think of an owner with a dozen small clients, none of whom issues a 1099. Or a business owner whose tax return shows modest net income after legitimate deductions, while the account shows steady revenue.

Here is a scenario. Say you run a small design studio with six to eight regular clients. Few of them send 1099s, and your write-offs are heavy. A 1099-only loan would have almost nothing to read. A bank statement file lets the lender average a year of real deposits, apply an expense factor, and land on a qualifying income that reflects the business.

The bank statement route also brings the higher leverage on a primary residence. Select lenders in the network go up to 90% LTV on a purchase or rate-term refinance, and the strongest files get the top of that range. A related option is asset depletion, which qualifies from liquid assets and runs to about 80% LTV on a primary residence. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Where it gets tricky: clean statements matter. Commingled personal and business money, unexplained transfers, large unsourced deposits, and declining monthly totals are the usual reasons these files stall. Keep one account for business revenue, and be ready to explain anything unusual.

Across the wholesale network, a pattern shows up. Borrowers who open a dedicated business account a few months before applying tend to have the easiest time, because the deposit history is simple to read. Those who run everything through one personal account spend more time documenting what each deposit was.

When the 1099-Only Loan Is the Better Fit

It is the better fit when one or two payers cover most of your income, they issue 1099s, and the forms tell the story well. A commission earner or a long-term contractor with a steady client is the textbook case. The paperwork is lighter, because the forms are the starting point and the lender does not have to sort through a year of deposits.

Say you contract for one company and have 1099s for the last two years that show steady, rising income. You have modest write-offs and no side business. The forms are clean, the payer is easy to verify, and the review is straightforward. A bank statement file would add work without adding qualifying income.

It also works for people whose real expenses are high. A real estate agent, for example, may see a taxable income number that is not far from the deposit-based result, so neither alt-doc path may beat the usual route for them. Run both calculations if you can.

Limits to know. Gross 1099 income does not capture side income paid without a form. Platform income reported on a different type of form can look different from your deposits. A payer name that does not match your business entity can also trigger questions. And most lenders want about two years of self-employment history, though some accept one year with a related work background.

What About Mixed Income?

If you have both 1099 forms and deposits from other clients, you do not have to pick blindly. Ask the broker to run both calculations and see which produces the higher qualifying income. Some programs allow either. Others lock you into one. This is a place where seeing many lenders’ guidelines helps, because the strictest overlays and the friendliest ones can differ a lot on the same file.

Why Statements and 1099s Often Don’t Match

Timing is the first culprit. A 1099 covers a calendar year, while a 12-month statement window covers the most recent twelve months. Income that grew late in the year looks different in each.

Second, a client may pay you late, so a deposit lands in a different period than the work. Third, some payers fall below reporting thresholds and issue no form. Fourth, a form may list your personal name while the deposits go to a business account. Expect questions on each gap, and bring a short written explanation before the underwriter asks.

Why Twelve Months?

A 12-month window is shorter than the 24-month option some programs use. The upside is that it leans on recent performance, which helps if your business has grown. The downside is the same fact: if income dipped recently, there is less history to offset it. Declining deposit trends get close attention. If your best year was two years ago, a longer window may fit better, and a lender’s program sheet will tell you whether it is allowed.

Occupancy Decides Which Rules Apply

Here is the part many self-employed investors miss. A bank statement loan on an owner-occupied home, meaning a primary residence or second home, is a consumer mortgage, and consumer disclosure rules apply. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is a business-purpose loan and is exempt from those disclosures.

That distinction has a practical effect. The Federal Register’s ability-to-repay final rule says business-purpose loans fall outside the ability-to-repay provisions, and that investment-purpose loans count as business-purpose. Lenders pay close attention to the stated purpose. Occupancy and loan purpose drive the label, not a casual description of the property.

For rentals, there is usually a better tool. DSCR loans are designed for non-owner-occupied investment properties, and they qualify primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal deposits and 1099s matter far less. Investment cash-out on alternative documentation tops out around 75% LTV, and investment purchase leverage varies by lender. Entity-titled borrowing is subject to program terms.

Document Checklists

For a 12-month bank statement file, gather:

• Twelve consecutive months of complete statements, all pages
• A written explanation for large or unusual deposits
• Proof of business ownership and how long it has operated
• A CPA or tax preparer letter if you want to document a lower expense ratio
• Evidence of reserves, commonly around six months of the housing payment

For a 1099-only file, gather:

• One to two years of 1099 forms, per program
• ID and a work-history or business verification
• A year-to-date profit-and-loss statement, if the lender asks
• Matching bank deposits that support the forms
• The same reserve documentation

Where Files Stall

• Declining income. Deposits or 1099 totals that fall over time shrink the average. Explain the cause in writing.
• Commingled accounts. Mixing personal and business money makes the screening harder. Separate them.
• Unsourced deposits. Cash and unexplained transfers get stripped out or questioned.
• Name mismatches. The payer, the form, and the account should line up. If they do not, document why.
• Short self-employment history. Most lenders want about two years. Some accept one with related experience.

Which One Should You Choose?

Pick bank statements if you have many clients, deposits that tell your story, or write-offs that make your taxes understate your income. Pick 1099-only if one or two payers issue clean forms that already show what you earn. Pick neither for a pure rental purchase, where DSCR is the more natural fit.

Both are legitimate. Neither is easier in any universal sense. The better file is the one whose documents match your real income with the fewest questions.
