How Much More Down a Bank Statement Loan Asks With One Year of Returns

The Quick Read: There is no universal extra percentage. Down payment on a bank statement loan comes from each lender’s matrix, which weighs credit, occupancy, loan size, reserves, and how long you have been self-employed. Twelve months of statements is the standard documentation window across the lenders Lendmire places files with, so that window alone usually does not add to your down payment.

• On a primary residence purchase, the strongest files reach up to 90% LTV, which means 10% down, subject to lender guidelines.
• A thin self-employment history, not the 12-month statement window, is what can lower your allowed LTV.
• Cash-out ceilings are lower: about 75% on investment property and second homes, and up to 80% on a primary residence.
• Reserves of roughly six months of the housing payment are common, so plan cash for the down payment and the reserves together.
• Ask for the program matrix, not a headline minimum. Headline numbers belong to the strongest files.

Which One Year Do You Mean?

“One year of returns” gets used for three different clocks. Mixing them up is a common source of confusion on this topic.

A bank statement loan is reviewed on documented income under the applicable program, subject to lender guidelines. The income comes from your deposits, not from your traditional personal-income documentation. So a single filed return does not block you. It simply means a standard full-doc file is off the table, and the file lands in a lender-set matrix instead.

That matrix is where the down payment gets decided.

Why a Thin-History File Asks for More Cash

A shorter business history gives the lender less proof that your deposits will keep arriving. Leverage is the lender’s cushion against that doubt. When the proof is thinner, the cushion gets thicker, and the cushion is your equity.

NerdWallet frames a down payment as a percentage of the purchase price, and a larger one lowers the lender’s risk. Same logic here. More skin in the game offsets a shorter track record.

Non-QM underwriting is also hands-on. Scotsman Guide describes it as mostly manual and notes that non-QM loans are not necessarily high risk. An underwriter reads the file as a story. A business with a clean year of deposits and prior experience in the same field tells a better story than a business that opened three months ago.

Here is how the income side works in practice. The lender screens out transfers, loan proceeds, refunds, and one-time items. On business accounts, it applies an expense factor. Trade press such as Scotsman Guide uses 50% as its example, with a P&L or a third-party expense statement as the alternative. That 50% is an illustration, not a rule. Programs differ, and no expense factor is promised to anyone.

Then the lender averages the remaining deposits over the months in the window, prorates for your ownership share, and runs credit, reserves, and the property. The LTV comes last, read off the matrix. Your down payment is 100% minus that LTV.

How Much More Down? The Percentages

On a primary residence purchase, the top of the range is up to 90% LTV, so 10% down at best. LTV, or loan-to-value, is the loan balance divided by the property value. Trade press agrees that non-QM LTVs can reach as high as 90% with no mortgage insurance requirement. Across Lendmire’s wholesale network, the top tier goes to stronger files: good credit, solid reserves, and a deposit history that trends flat or up.

A weaker file does not get the top tier. It steps down the matrix. How far it steps depends on the lender, and that is the honest answer to the title. Nobody publishes a flat percentage because none exists.

The table below shows the program ceilings, which are the best case for a strong file. Equity kept is simply 100% minus the LTV. On a purchase, that equity is your down payment.

All figures are typical ranges, vary by loan size and credit, and are subject to lender guidelines. Loan sizes generally run from $125,000 to $3,500,000.

One caution on that last row. Investment purchase leverage on bank statement documentation varies a lot between lenders.

What Moves the Number

Five levers move your allowed LTV. Some matter more than others, and each lender weights them differently.

Credit is usually the biggest single lever. A top-tier score can offset a short history. A middling score plus a short history is where files get pushed toward the lower end of the matrix.

Deposit trend deserves its own look. The underwriter reads the direction of your deposits, not only the average. A decline can wipe out any benefit of a shorter window. For how lenders treat a dip, see Lendmire’s piece How One Down Year vs a Multi-Year Decline Changes Bank Statement Qualifying.

Here is the flip side. If your income is climbing, the 12-month window can work for you. Say your prior year ran well below your recent year. A 12-month window reads only the strong recent deposits. A 24-month window would blend in the weaker year and land halfway between the two. Rising income therefore tends to qualify higher on 12 months. The cost is not a bigger down payment. It is that some lenders cap or tighten shorter-history files.

Down Payment or Reserves?

You rarely get to choose one over the other. Most programs want both. Reserves commonly run around six months of the housing payment, and they sit on top of your down payment and closing costs.

So the real question is where to put your last dollar of cash. Two files with the same total cash can read differently.

• More down, thinner reserves. A lower LTV makes the loan safer for the lender, but a lender that wants six months of reserves will not waive them because you put more down.
• Less down, deeper reserves. A higher LTV with strong reserves often reads better than a lower LTV with no cushion, especially on a thin-history file.

Add the pieces together before you shop. Down payment, closing costs, prepaid items, and reserves all come due. A borrower who plans for the down payment alone is often short at the table.

There is one more option if you hold a lot of liquid assets. Asset depletion is reviewed against those assets rather than deposits, up to about 80% LTV on a primary residence. It suits borrowers whose business deposits look thin but whose savings are deep. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

One Year of Returns on a Conventional File vs a Bank Statement File

Conventional full-doc loans normally read two years of traditional personal-income documentation. Some borrowers with one year of returns can still get a conventional loan if the business is established and the rest of the profile is strong. That file leans on compensating factors such as down payment, reserves, and credit. If you fit that mold, ask about it. It can be a fine route.

The bank statement route works differently. It reads deposits instead.

The deciding question is how your returns look after deductions. Many self-employed borrowers write off enough expenses that taxable income looks small. Deposits then tell a stronger story than returns do. If your returns already show strong income, the conventional path may cost you less cash, and the bank statement loan adds nothing.

Decision Table by Situation

Use this as a first read, not a verdict. Every file is underwritten individually.

Notice that the window length is not a column. The history, the trend, and the credit are.

Documents That Prove Prior Work and an Active Business

When history is short, the file needs proof beyond the statements. Lenders in the network commonly look for:

• Twelve months of business or personal bank statements, consecutive and complete.
• A business license, registration, or similar proof the business operates.
• Evidence of prior work in the same field, such as past pay records, an old license, or a letter from a former employer.
• A CPA or third-party expense statement, where the program allows it, to support a lower expense factor.
• Proof of liquid reserves.

The CPA letter matters most on business accounts. Personal statements are usually read closer to raw deposits, though the lender may still ask for proof the business is real. Tax treatment varies by how income is reported, so consult a qualified tax professional before changing how you file.

When a Bank Statement Loan Is the Wrong Tool

Skip it if your returns already show strong, steady income. A conventional loan will likely cost less cash.

Skip it too if your business is brand new, your deposits are erratic, and you have no same-field history. No window or expense factor fixes that. Waiting a few months can change the read more than any structure.

And if the property is a pure rental, think twice. A bank statement loan fits an owner-occupied purchase better. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. Owner-occupied bank statement files follow consumer mortgage disclosure rules. A non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from them. 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.

For a first rental with no rental history and thin personal income, the DSCR side is worth comparing. Some programs qualify primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide walks through that path.

Key Terms Defined

Bank statement loan: a mortgage that is reviewed around documented income from your deposits rather than conventional personal-income paperwork.

LTV (loan-to-value): the loan balance as a percentage of the property’s value; the down payment is 100% minus the LTV.

Expense factor: the share of business deposits a lender treats as operating costs before counting the rest as income.

Reserves: cash or liquid assets left after closing, commonly around six months of the housing payment.

Non-QM: a loan that falls outside standard agency-style boxes and is underwritten on its own program guidelines.

Seasoning: the length of time you have been self-employed or in business.
