How Lenders Size Down Payment on a 1099-Only Self-Employed Mortgage

The Quick Read: Lenders do not pick a down payment directly. They set a maximum loan-to-value (LTV) cap from stacked risk layers: credit, occupancy, loan size, property type, and how thin the income paper trail is. The down payment is whatever is left over, which is 100% minus that cap, applied to the lesser of price or appraised value.

• On a primary-residence purchase or rate-term refinance, select lenders in Lendmire’s wholesale network go up to 90% LTV, and stronger files earn the top of that range.
• Owner-occupied cash-out is lower: up to 80% LTV on a primary residence (75% with an accountant-prepared expense ratio) and up to 75% on a second home.
• Investment-property cash-out tops out around 75% LTV, while investment purchase leverage on bank-statement documentation varies by lender.
• Loan sizes typically run from $125,000 to $3,500,000, with reserves commonly around 6 months of the housing payment.
• Every file is underwritten individually, so these are typical ranges and not commitments to lend.

A friend of mine in the business likes to say the down payment is the lender’s answer to one question: how much of this can go wrong before we lose money? That is the right way to read everything below.

What Does “1099-Only” Underwriting Actually Mean?

A 1099-only loan is reviewed around income that payers reported to the IRS, not on your tax-return net profit. It is a non-QM product, meaning it sits outside the standard agency box built around W-2s and traditional personal-income documentation. It exists because write-offs shrink the income on a return, sometimes well below what you really earn.

A 1099-NEC is the form a payer files to report money paid to a non-employee for services. Per the IRS, payers report these payments on that form once they cross the filing threshold. Lenders generally read the form as gross receipts, not profit. Then they apply an expense factor to reach qualifying income.

In Lendmire’s network, the more common path for self-employed borrowers is bank-statement documentation. That means 12 months of business or personal statements, with income drawn from deposit averages and lender-specific expense factors. Across the wholesale network, the sizing logic is the same whichever paper trail you use. Only the thickness of the paper changes the layers.

The program reviews the file on documented income under the applicable program, subject to lender guidelines. It is not a no-paperwork loan. The lender still has to verify what it relies on. The CFPB’s compliance guide says that verification must use reasonably reliable third-party records, and that a lender generally cannot rely on what you say out loud about your income.

How Does a Lender Land on One Number?

The lender starts with a matrix and walks your file down it, taking the lowest limit it hits. Here is the sequence on most programs we place files with.

1. Classify the documents. Are these 1099s, bank statements, or something else? The paper type picks the program.

2. Calculate qualifying income. Gross receipts get an expense factor. The factor varies by lender, so never assume a universal formula.

3. Place the file in a matrix row. Credit tier, occupancy (primary, second home, investment), and transaction type (purchase, rate-term, cash-out) set the starting LTV cap.

4. Apply the layers. Loan size, property type, debt-to-income (DTI), reserves, and self-employment history can each trim the cap.

5. Convert the cap to cash. Down payment equals 100% minus the LTV cap, multiplied by the lesser of the purchase price or the appraised value.

6. Document the cash. The funds to close and the reserves need a paper trail.

DTI is your monthly debts divided by qualifying monthly income. A 1099 or bank-statement file tests it. A DSCR file generally does not, which matters later.

Which Risk Layers Move the Number?

Each layer pushes the down payment up or down, and you can influence some of them. The table below shows direction, not program figures.

Documentation deserves a note. Some programs cut the maximum LTV a bit for 1099-only files, because that paper trail is thinner than a full-doc file. Others do not. That is exactly the kind of variation you see by comparing many guideline sheets.

Where Does Income Stability Fit?

Lenders want to see that your income is steady and likely to continue. Declining income draws extra scrutiny. In practice, the lender may use the lower figure or steer you to a different program.

Payer concentration matters too. A file built on one payer looks riskier than one spread across several, and the layers can reflect that.

A Worked Example, Receipts to Cash

Run the chain with modeled inputs, not sourced market data. Say a contractor buys a $500,000 primary residence. The lender takes gross receipts, applies its expense factor, and lands on qualifying income. That income feeds DTI. If DTI is comfortable and credit is strong, the file may reach the top of the primary-residence range, which is up to 90% LTV on a purchase. The down payment is then about 10% of the price. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

Now change one layer. Same buyer, same income, but this time the home is a second home. The cap on a cash-out would sit at up to 75% LTV, and purchase leverage on a second home generally runs below the primary-residence ceiling. The down payment grows because occupancy changed, not because the income changed.

Change another. Suppose the appraisal comes in under the contract price. The lender sizes the loan on the lesser of price or value, so the gap comes out of your pocket. A 10% down plan can become a larger cash requirement overnight. Keep a cushion for that. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

Down Payment, DTI, and Reserves Trade Off

More cash down can offset a weak layer, but it is not unlimited. Here is how the trade usually runs.

• If DTI is tight, a lower LTV can soften the file, though a hard DTI ceiling still applies.
• If credit is thin, a bigger down payment may keep the file in range.
• If reserves are short, no down payment fixes that. Reserves, commonly around 6 months of the housing payment, are a separate test.

Here is the catch: reserves and down payment both come from verified assets. Cash you put into the house is cash you cannot also count as reserves. Plan the savings target as three pieces: down payment, closing costs, and reserves.

Where Can the Money Come From?

Funds to close must be documented. Expect asset statements covering the down payment and reserves. Large, unexplained deposits draw questions, so keep a clean trail from where the money sat to where it lands. If you are using business-account funds, be ready to show that pulling them out does not hurt the income the lender is counting. Gift funds and sale or retirement proceeds follow each lender’s own rules, and these vary across the network.

Asset depletion is a different path worth knowing. It is reviewed against liquid assets instead of income, and it runs up to about 80% LTV on a primary residence. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Where the General Rule Breaks

A few edge cases shift the picture.

• Entity-paid 1099s. Programs differ on whether 1099s issued to an LLC count. Some want them payable to you personally. Others accept an LLC with a CPA letter confirming ownership. This is lender-specific.
• Mostly non-1099 income. Some programs expect 1099 income to be the primary source. A mixed W-2 and 1099 file may fit another program better.
• Short history. Under two years may work with prior experience in the same field, depending on the lender.
• Declining income. The lender may use the lower figure. Bank statements may fit better if deposits tell a stronger story than the forms.
• Rental purchases. This is the big one, covered next.

Should an Investor Use a 1099 Loan at All?

Often not. A 1099 or bank-statement loan tests your personal income and DTI. A DSCR loan tests the property: whether its rent covers its payment. DSCR stands for debt service coverage ratio, and it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. For a self-employed investor with heavy write-offs, that sidesteps the personal-income test. Lendmire’s complete DSCR loans guide covers how that works.

Leverage on rentals is the practical difference. A bank-statement cash-out on an investment property tops out around 75% LTV. Investment purchase leverage on bank-statement paper varies by lender, so treat it as a question to put to the file. Each additional financed property can also add to personal DTI on the 1099 route, which is one reason investors who scale often move to DSCR.

Occupancy decides the paperwork too. A bank-statement loan on 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 business-purpose and exempt from those rules. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.

Key Terms Defined

LTV (loan-to-value): the loan amount divided by the lesser of price or appraised value.

Risk layer: a single factor, such as credit or property type, that can lower the maximum LTV.

Reserves: liquid assets left after closing, counted in months of the housing payment.

DTI (debt-to-income): your monthly debts divided by qualifying monthly income.

Seasoning: how long funds or ownership have been in place before a lender will count them.

Non-QM: a loan outside the standard agency box, underwritten on the lender’s own guidelines.

Ways to Lower the Cash You Need

You can move the number legitimately.

• Clean up credit before you apply, since the credit tier is often the first row of the matrix.
• Document a longer, steadier income history.
• Compare doc types. If deposits look stronger than your 1099s, bank statements may fit better.
• Consider a different property type or occupancy if the deal allows it.
• For rentals, run a DSCR comparison before committing to a personal-income program.

Myths Worth Dropping

“There’s a standard 10% or 20% down payment.” No rule sets one. The federal ability-to-repay rule, Regulation Z section 1026.43, requires lenders to evaluate whether you can repay, but it sets no minimum down payment. Each lender’s matrix sets the cap. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

“1099 loans need no documentation.” Wrong. Lenders still verify income and assets.

“All my gross receipts count.” Lenders typically apply an expense factor.

“A bigger down payment guarantees approval.” It can strengthen a file, subject to lender guidelines, but it does not replace the other tests.
