How a Bank Statement Loan Sizes the Down Payment on a $600K Purchase

The Quick Read: The down payment equals 100% minus the maximum loan-to-value ratio the lender’s program allows for your occupancy, credit, and loan size, so on a $600K purchase the program matrix, not a federal rule, sets your cash, while your deposits only decide whether you can carry the loan.

• Up to 90% LTV is available through select lenders on a primary-residence purchase, subject to lender guidelines.
• Investment-property purchases on bank statement documentation vary by lender, and the top leverage tier is not the norm.
• Loan size, credit, reserves, and the appraisal all move the number.
• Deposits set your income. LTV sets your down payment. They are separate dials.
• A $600K purchase sits comfortably inside the roughly $125,000 to $3,500,000 loan range.

What Is the Actual Down Payment Formula?

The formula is simple: down payment percentage equals 100% minus the permitted LTV. LTV, or loan-to-value, is the loan balance divided by the property’s value. Multiply the price by the down payment percentage and you have the cash figure. The site’s illustrative calculator does that conversion for you.

Here is the arithmetic on a $600K price at four leverage levels. These are math illustrations, not program promises.

Every five points of LTV moves five percent of the price. On $600K, that is a meaningful swing in how much cash leaves your account. Which row you land on depends on the file, and the next sections explain why.

How Does a Bank Statement Loan Size the Down Payment Step by Step?

Underwriting runs in a set order. Each step answers a different question.

Step one: the documentation. The lender reviews 12 months of business or personal bank statements instead of tax-return income. The statements replace the traditional personal-income documentation. They do not replace documentation.

Step two: the income. The underwriter averages your deposits, strips out transfers, loan proceeds, and one-time credits, and applies a lender-set expense factor on business accounts. Lenders differ on that factor. Some accept a lower ratio when an accountant prepares it. Treat any single percentage you read online as a typical default, never a universal rule.

Step three: the debt test. Qualifying income is measured against your total monthly obligations, including the new housing payment. This test applies at every leverage level. A higher LTV tier does not fix thin income. Experian’s explainer on bank statement loans notes that lenders also review credit score and debt-to-income, and that borrowers may need a larger down payment and liquid assets than on a conventional loan.

Step four: the leverage cap. The program matrix sets the maximum LTV from your occupancy, credit tier, loan amount, statement window, and reserves. This step sizes the down payment.

Step five: the appraisal. LTV is generally measured against the lower of the purchase price or the appraised value. That is standard practice, though matrices differ in detail.

So income answers “can you carry this loan?” and LTV answers “how much cash goes in?” Mix them up and the whole file looks confusing.

Key Terms Defined

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

Down payment: the share of the price you pay in cash, equal to 100% minus the LTV.

Expense factor: the percentage of business deposits a lender treats as operating costs when it turns deposits into income.

Reserves: liquid funds you hold after closing, commonly around six months of the housing payment on these programs.

Cash to close: the down payment plus closing costs, prepaids, and escrow funding, less earnest money already paid.

Occupancy: how you will use the property: primary residence, second home, or investment.

What Moves the Percentage on a $600K Purchase?

Occupancy is the biggest lever. Across the wholesale network Lendmire places files with, the strongest leverage is reserved for primary residences. Select lenders go up to 90% LTV on a primary-residence purchase or refinance, and stronger files earn the top of that range. An asset-depletion alternative, which is reviewed against liquid assets instead of deposits, runs to about 80% LTV on a primary residence.

Second homes and investment properties sit lower. Investment purchase leverage on bank statement documentation varies by lender. Don’t assume the 10%-down headline applies to a rental. Most programs we see price or cap that tier differently, and a few lenders simply don’t offer it on investment purchases.

Credit comes next. A stronger score tends to earn the higher leverage tiers, while a weaker one pushes the cap down and the cash required up. Loan size matters too. Larger balances usually face tighter leverage and heavier reserve requirements, though the exact steps differ between programs. A $600K price is mid-range for this product, so you are rarely at the strictest tier, but you are not at the simplest one either.

Documentation length also matters. Twelve months of statements is the baseline in this lane. Some lenders prefer 24 months for the highest leverage or for volatile deposits. Reserves, property type, and the appraisal round out the list.

Here is how three hypothetical buyers of a $600K home might land:

• Strong file, primary residence: clean deposits, high credit, ample reserves. This buyer may reach the top of the range, up to 90% LTV on a purchase.
• Average file, primary residence: solid but not exceptional credit, normal reserves. This buyer more often lands in a middle tier, so a larger share of the price goes down.
• Rental purchase: leverage varies by lender and tends to run lower. This buyer should expect a materially higher down payment percentage than the primary-residence headline.

Why the Lowest Down Payment Isn’t Always the Right One

The 10% tier looks attractive, but a more affordable down payment is not always the best structure. A program that allows the thinnest cash outlay can price that tier less favorably than a modestly larger down payment. Lower leverage can also improve how the file reads on reserves.

Think about liquidity. Money you put down is money you no longer hold as reserves. Lenders want to see roughly six months of the housing payment left over after closing, and those funds must stay separate from what you use at settlement. A buyer who drains cash to reach the lowest percentage may fail the reserve test, or may be left without a cushion when business income dips. That cushion matters more for the self-employed than for salaried buyers.

Here’s a clean way to decide. Run the file two ways, at the maximum LTV and at a step below it. Compare the cash to close, the remaining reserves, and the resulting debt test. Pick the version that leaves you safe, not the one that wins on one number.

Cash to Close Is Bigger Than the Down Payment

Down payment is one line. Closing costs, prepaids for taxes and insurance, and escrow funding sit on top of it. Earnest money you already paid is credited against the total. Reserves live outside that pile entirely.

The practical checklist before you commit:

• Down payment percentage times the price.
• Closing costs, prepaids, and escrow funding.
• Reserves, held separately and verified.
• A cushion for a low appraisal.

Down-payment funds must also be documented. Typical practice is two months of asset statements, and source and seasoning rules vary by program. Moving money between a business account and a personal account is where self-employed files stall. Large unexplained transfers raise questions. Keep a paper trail before you apply, not after.

What Happens If the Appraisal Comes In Low?

The loan shrinks, and your cash grows. Because LTV applies to the lower of price or value, the lender’s cap is a percentage of the appraisal.

Run the numbers with percentages only. Say the home appraises at 97% of your $600K contract price and the program allows 90% LTV on a primary-residence purchase. The loan is capped at 90% of the appraised value, which equals 87.3% of the price. Your cash down becomes 12.7% of the price instead of 10%. The percentage on the program sheet did not change. The base it applies to did. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

You then have options: renegotiate the price, bring the extra cash, dispute the appraisal with comparable sales, or walk away if your contract allows. Hold a cushion for this scenario before you make the offer.

Where the Rulebook Changes: Owner-Occupied vs. Rental

Occupancy decides which disclosure regime applies, and the two cases look different on paper. An owner-occupied bank statement file, whether a primary residence or a second home, is a consumer mortgage, and TRID disclosures apply. The lender must also make a reasonable, good-faith determination that you can repay, as set out in the federal ability-to-repay rule, which also requires the lender to verify the income or assets it relies on. Bank statements are a recognized way to do that, and the CFPB’s compliance guide lists account statements among usable income records.

Neither rule sets a down payment percentage. That stays a lender risk decision.

A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from TRID. Say which regime applies to your property before comparing offers, and don’t mix the two. Pricing and payment figures live in the calculator only, never here.

Should You Pick Bank Statement or DSCR for a Rental?

Match the loan to the asset. A bank statement loan tests your deposits. A DSCR loan, which qualifies primarily on property-level rental income covering the payment, tests the property. For a pure rental, DSCR often fits more naturally, because the property carries the file and your personal income is not the constraint.

Scaling is the other reason. Each bank statement loan stacks onto the same personal income, so your debt-to-income can become the ceiling by the third or fourth purchase. DSCR files lean on each property’s own rent, so they stack differently. Lendmire’s complete DSCR loans guide lays out leverage, coverage ratios, and documents for that path. Programs below 1.00 coverage are available through select lenders in the network, though leverage and terms adjust.

Buying a home to live in is the opposite case. Bank statement documentation is built for that, and the leverage is meaningfully higher. If your down payment will come from home equity, Lendmire’s piece How to Fund a DSCR Purchase Down Payment With a Bank Statement HELOC covers that route. If the property is a vacation home you will use yourself, see Lendmire’s article How to Source a Down Payment on a Second-Home Bank Statement Loan.

Tax treatment varies; consult a qualified professional.

Where Files Go Wrong

Messy deposits cause most of the trouble. Commingled personal and business accounts, large one-time transfers, and declining monthly totals all weaken a bank statement file. Clean them up early.

Another trap is assuming a deposit counts because it hit the account. Transfers between your own accounts, loan proceeds, and refunds typically come out of the average. Your qualifying income can be well below your gross deposits.

Finally, don’t confuse non-QM with bad credit. The label means the loan falls outside standard qualified-mortgage rules, usually because income is documented differently. It does not mean no underwriting. Every file is reviewed individually, and qualification is on documented income under the applicable program, subject to lender guidelines.
