How a Bank Statement Loan Sets Down Payment for a Portfolio Investor

The Quick Read: A bank statement loan does not set the down payment directly; it sets how your income is measured, and the maximum loan-to-value the lender allows on the file sets the cash you put down. Credit, loan size, and occupancy move that ceiling up or down, and for a portfolio investor the property type and existing leverage matter just as much.

• Down payment equals the purchase price minus the maximum LTV the file earns.
• Primary-residence purchases on bank statements run up to 90% LTV through select lenders; investment-property leverage varies by lender.
• Investment cash-out tops out around 75% LTV, subject to lender guidelines.
• Reserves of roughly 6 months of the housing payment sit on top of the down payment.
• Deposit quality and the expense factor decide the income, which in turn decides how much leverage the file can carry.

A bank statement loan is reviewed on documented income under the applicable program, subject to lender guidelines. That sentence matters because it explains why no single published minimum exists. Across the wholesale network Lendmire works with, the leverage a file earns comes from stacked layers, and a portfolio investor sees those layers more sharply than a first-time buyer does.

Key Terms Defined

Down payment: The cash you pay at purchase, equal to the price minus the loan amount.

LTV (loan-to-value): The loan amount divided by the property’s value or price, expressed as a percentage.

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

Reserves: Liquid funds you keep after closing, separate from the down payment, usually counted in months of the housing payment.

Cash to close: Down payment plus closing costs, with reserves verified on top.

Who Actually Sets the Number?

Three layers set it, and they bind in a fixed order. First comes the investor guideline, meaning the capital source that buys the loan and publishes a maximum LTV grid. Second is the lender overlay, where the originating lender tightens that grid for its own risk appetite. Third are the file’s own risk factors: credit score, loan amount, occupancy, DTI, and reserves.

The lowest of the three wins. A program can advertise a high ceiling, yet a mid-range credit score, a large loan, and an investment property can each cut it. Stacking is why two lenders can look at the same file and hand back different tiers. For a portfolio investor, that variation is a reason to compare, not a reason to anchor on a headline figure.

How Underwriting Treats the Statements, Step by Step

The path from deposits to down payment runs in a straight line.

1. Choose the statement set. Personal or business statements, depending on how you are paid. Twelve months is the common baseline in Lendmire’s lane.

2. Strip non-income deposits. Transfers between your own accounts, loan proceeds, and refunds come out before averaging.

3. Apply the expense factor. On business accounts, the lender discounts gross deposits for operating costs. The factor is lender-specific, and a few programs allow an accountant-prepared ratio instead of the default.

4. Run debt-to-income. Qualifying income is tested against your debts, including the new payment on the property you are buying.

5. Assign the LTV cap. Credit, loan size, occupancy, and the DTI and reserve picture feed the grid. The cap fixes the minimum down payment.

6. Verify the funds. Down-payment money needs a documented source. Business funds typically require proof of ownership or an access letter.

7. Count reserves separately. About 6 months of the housing payment commonly sits behind the loan.

Income does not have to be salaried to count. The federal consumer-finance regulator’s repayment-capacity/qualified-mortgage small entity compliance guide confirms that rental income and other non-wage sources can be considered in a repayment-capacity review. That is why self-employed borrowers can document income through deposits at all.

The Five Levers That Move Your Cash Required

Each lever pushes leverage in a known direction. Some you control. Some you don’t.

Occupancy is the biggest structural break. A primary-residence purchase on bank statements can reach up to 90% LTV through select lenders, with stronger files earning the top of that range. Investment-property purchases don’t follow that figure. Leverage there varies by lender, and the portfolio investor should treat any primary-residence number as irrelevant to a rental purchase.

Worked Example: Two Investors, Same Property

Picture two self-employed investors, each buying the same rental. The figures below are modeled for illustration, not market data.

Investor A’s deposits average cleanly after transfers are removed, so qualifying income holds. Investor B’s account mixes personal and business money, which forces exclusions and a lower qualifying income. The same price now needs more equity from B, because weaker income and a larger loan each push the cap down.

The stack looks the same for both: down payment, plus closing costs, plus reserves verified after closing. Loan amounts across Lendmire’s bank statement lane run from roughly $125,000 to $3,500,000, and the larger the loan, the more the grid tends to tighten.

Portfolio Scenarios: First Rental Versus Fifth

A portfolio investor faces a different question than a one-property buyer. The question isn’t only how much to put down. It is how much cash each door ties up, and whether personal DTI survives the next purchase.

Consider a few cases:

• First rental, strong deposits. DTI is light, so the LTV grid and credit drive the number.
• Third or fourth financed property. Each new payment enters DTI. Income that looked ample at property one may look thin now.
• Sequencing purchases. Closing the highest-leverage file first can leave less DTI room for the next. Planning the order matters.
• Cash-out to fund the next door. Investment-property cash-out tops out around 75% LTV, so pulling equity from a rental yields less than an owner-occupied cash-out, which reaches up to 80% LTV with a fixed expense ratio (75% with an accountant-prepared ratio). Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Here is where the general rule breaks. When personal DTI is the binding constraint, more cash down does not fix it. Equity lowers collateral risk, but it doesn’t replace income. Treat extra equity as a collateral tool, never an income substitute.

Edge Cases Where the Rule Breaks

Overlay stacking. A lower credit score, a large loan, and an investment property each trim the cap. Together they can raise the cash required sharply.

Commingled accounts. Deposits that blend personal, business, and transfer money get haircuts or exclusions, shrinking income.

Asset depletion. Qualifying from liquid assets instead of deposits runs to about 80% LTV on a primary residence. It is an owner-occupied option, not a rental one. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

Disclosure regime by occupancy. An owner-occupied file, meaning a primary residence or second home, is a consumer mortgage, and TRID applies. The CFPB’s Regulation Z text exempts credit extended primarily for business purposes and says the creditor must decide the primary purpose in each case. Know which regime your property falls under before you budget.

Bank Statement Versus a Property-Income Loan

For a portfolio investor, the choice often comes down to what constrains you: your income or the property’s.

If you hold several leveraged rentals, personal DTI tends to bind first, and a DSCR loan, which tests the property rather than you, usually fits better. Lendmire’s piece comparing a DSCR loan with a bank statement loan for investors walks through that decision. If you are self-employed with strong deposits, few financed properties, and a rental that doesn’t yet cover its own payment, the bank statement route can be the cleaner path. The complete DSCR loans guide covers the property-income side in depth. Programs below 1.00 coverage are available through select lenders in the network, though leverage and terms adjust.

How to Lower the Cash You Need

Only legitimate levers work, and they are mostly about the file:

• Clean the deposits. Run business income through one account and keep personal transfers out of it.
• Document the expense picture. An accountant-prepared ratio can beat a default factor when your real costs are low.
• Lift the credit score before applying, since score steps usually move the grid.
• Hold reserves in liquid form, separate from the down payment.
• Compare lenders. Because overlays differ, the same file can land in different tiers.

Source the down payment with the same care. Seasoned funds in your own name are simplest. If the money sits in a business account, bring ownership proof or an access letter.

Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
