How a Lender Sets the Minimum Down Payment on a Bank Statement Loan

The Quick Read: On a bank statement loan, the lender sets the minimum down payment by working backward from the maximum loan-to-value ratio its program matrix allows for your specific file, so the minimum equals 100% minus that LTV. No national rule fixes the number. Credit, loan size, occupancy, property type and transaction purpose all move it.

• The down payment is 100% minus the maximum LTV the matrix returns for your file.
• On a primary residence, select lenders in Lendmire’s network go up to 90% LTV on a purchase or rate-term refinance, which is a ceiling and not a promise.
• Cash-out leverage is lower: up to 80% on a primary residence, up to 75% on a second home, and around 75% on an investment property.
• Down payment, closing costs and reserves (commonly around 6 months of the housing payment) are separate cash buckets.
• Occupancy decides which disclosure regime applies to the file.

Self-employed borrowers often ask what the minimum is as if it were a published rule. It isn’t. Across the wholesale network Lendmire works with, the number comes out of a grid, and the grid changes by lender. This piece walks through how that grid produces a percentage, where it breaks, and what it means for your cash.

Who Actually Sets the Number?

The lender, or the investor buying the loan, sets it. Bank statement loans are non-QM products, so there is no single standard rulebook behind them. Each program writes its own matrix.

That is also why the advertised number differs between lenders. A lender with a more conservative overlay may cap leverage lower than its peer for the same borrower. Seeing many programs side by side is the real advantage of a broker: the same file can return a different ceiling depending on where it is placed.

The ceiling is also not a verdict on your repayment-capacity. A federal summary of the repayment-capacity rule describes a verification standard: lenders must consider and verify income, assets and debts. It does not set a down payment floor. The cash you put down is a risk-pricing choice made by the lender’s matrix.

The Formula in One Line

Minimum down payment = 100% minus maximum LTV. Loan-to-value is the loan amount divided by the property’s accepted value. If the matrix returns 90% for your file, the minimum down payment is 10% of the accepted value. If it returns 75%, the minimum is 25%.

Higher LTV means more credit risk for the lender, since there is less owner equity cushioning a loss. Lower LTV shrinks that risk. That single relationship drives everything below.

How Underwriting Gets From File to Percentage

The sequence matters. Most borrowers assume the down payment is picked first, then income is tested. In practice, the order runs the other way.

1. Documentation type is set. The file is reviewed on documented income under the applicable program, subject to lender guidelines. Here that means 12 months of personal or business bank statements.

2. Income is calculated. The lender totals eligible deposits, strips out transfers and other non-income credits, applies an expense factor on business accounts, then divides by the number of months. Expense factors are lender-specific. Never assume a universal figure.

3. The matrix is read. The file lands on a grid that cross-references credit score, loan amount, occupancy, property type and transaction purpose. The grid returns a maximum LTV.

4. The value is fixed. On a purchase, the lender uses the lower of the contract price and the appraised value.

5. The loan ceiling is computed. Accepted value times maximum LTV gives the largest loan allowed. Reserves, credit and other overlays can pull the final figure lower.

6. Funds are verified. The cash you bring must be documented and sourced.

Lendmire’s own piece How Much More Down a Bank Statement Loan Asks With One Year of Returns describes LTV as the last number read off the matrix, not the first one chosen. That is the right mental model.

Which Factor Moves the Number Most?

Several inputs interact, and the most restrictive one usually binds. A strong credit score does not rescue a file that is penalized elsewhere. If a borrower with excellent credit requests a large loan on an investment property, the loan size and occupancy tiers often set the ceiling, not the credit.

What can a borrower change? Credit score, requested loan size and the transaction purpose are the three levers within reach. Occupancy and property type are usually fixed by the plan.

Why Bank Statement Loans Sit Above Conventional Minimums

Deposits are a looser proof of income than a tax return, so lenders price that uncertainty into leverage. Conventional programs backed by the agencies carry lower-down-payment options on owner-occupied homes. Alt-doc lenders have no such backstop, so they offer less leverage to compensate. Trade-press explainers on non-QM loans reach the same general conclusion: expect more cash down than conventional.

There is a useful flip side. Bank statement loans of this kind typically carry no mortgage insurance requirement, whereas conventional loans with under 20% down usually do. A larger down payment on a bank statement loan therefore buys different benefits than it does on a conventional one: lower leverage and, often, better pricing, not an insurance drop-off.

The Network Ranges by Occupancy

Here are the figures that apply across select lenders in Lendmire’s wholesale network, each tied to its transaction and occupancy. They are ceilings, subject to lender guidelines, and stronger files earn the top of each range.

Investment-property purchase leverage on bank statement documentation varies by lender, so it is better handled as a quote-by-quote question. Investors focused on rental leverage usually find the DSCR side of the market, which is reviewed on rent, more informative. Loan sizes run roughly $125,000 to $3,500,000.

Occupancy also decides the disclosure regime. An owner-occupied file, meaning a primary residence or second home, is a consumer mortgage and TRID disclosures apply. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from TRID. Know which applies before you compare quotes, and never assume the paperwork from one carries over to the other.

A Worked Example: Same Borrower, Three Files

Picture a self-employed borrower buying a $600,000 primary residence. Say the matrix returns a 90% ceiling. The down payment floor is 10% of the accepted value.

Now change one thing at a time:

• Credit slips a tier. The grid might return a lower ceiling, so the minimum rises above 10%.
• The appraisal comes in under contract. Suppose the home appraises well below the price. The lender uses the lower value, so the loan shrinks and the borrower covers the gap in cash. The effective down payment becomes larger than a flat percentage of the price suggests.
• Occupancy changes to a second home. If the same borrower instead bought the property as a second home, ceilings are lower than the primary-residence purchase ceiling.

Note what the example leaves out. Closing costs and reserves are not in the down payment. A realistic cash plan adds both.

Down Payment Is Not Your Whole Cash Need

Down payment, closing costs and reserves are three separate buckets. Reserves commonly run around 6 months of the housing payment, and borrowed funds, where allowed with documentation, are commonly accepted for the first two but often excluded from reserves.

Sourcing matters because the lender reads recent statements. Large unexplained deposits draw questions, so document where they came from. Gift-fund treatment varies by lender, and some matrices exclude gifts on investment purchases. Confirm before you rely on one.

What a Bigger Down Payment Can and Cannot Do

It can lower leverage and often improves pricing, since pricing tends to improve as LTV falls. It can also move a file from one matrix tier into a friendlier one.

It cannot replace documented income. A large down payment will not cure weak deposits, and bank statement files still get a full review of credit, assets, debts and the property. Bank statement does not mean no documentation.

Here’s the trade-off: more cash down reduces risk but ties up capital that might work harder elsewhere. A buyer with several deals in motion may prefer higher leverage and thinner reserves, while a buyer holding one long-term property may prefer more equity. Neither is right in every case.

Where the General Rule Breaks

A few edge cases deserve names.

• Tier boundaries. Sitting just below a credit or loan-size bracket can cost leverage, so a small change in the request can matter.
• Stressed markets. Lenders can trim LTVs and raise score floors when conditions tighten, which pushes the minimum up without any change in your file.
• Unit count and investor occupancy. Multi-unit and non-owner-occupied properties often need meaningfully more down than a single-unit primary home.
• Gift funds. Some programs allow them on owner-occupied purchases and bar them on investment purchases.
• Term length. Term options follow each lender’s program sheet. Do not assume a 40-year or interest-only structure on a bank statement loan, since those are DSCR-side offerings.

How to Compare Lender Quotes

Ask each lender the same questions in writing:

• What maximum LTV applies to my exact file?
• Does the loan use the contract price or the appraised value?
• How are business deposits treated, and what expense factor applies?
• What reserves are required, and do borrowed funds count?
• What is the total cash to close, including costs?

The goal is an apples-to-apples comparison. A lender advertising a high ceiling may not offer it to your profile.

If you’re weighing a bank statement loan against a DSCR loan for a rental, the logic differs: one is reviewed on your deposits, the other on the property’s rent against its monthly obligation. Run both and compare cash required. The complete DSCR loans guide explains how the rental-based side works.
