How Much Can You Borrow on a Bank Statement HELOC Draw as a Documented Rental Down Payment?

The Quick Read: It depends on your equity and on the purchase lender: the line tops out at 70% combined loan-to-value (CLTV) on an investment property or 90% on a primary home with a 720 or better credit profile, less existing liens, and the DSCR lender then decides how much of that draw counts as down payment. DSCR stands for debt service coverage ratio, which compares a rental’s income to its full monthly housing payment.

• The line is a formula: home value times the maximum CLTV, minus what you already owe against the home.
• An investment-property line caps at $500,000, while a primary-home line can run higher, up to $750,000, at a lower 75% CLTV cap above $500,000.
• A DSCR purchase typically needs 20%-25% down, and a fully borrowed down payment can fail a lender’s rules.
• Borrowed funds are often excluded from reserves, so reserves usually have to come from your own money.
• The line payment sits outside the new property’s DSCR, but it is still a real bill.

Key Terms Defined

CLTV (combined loan-to-value): Your first mortgage plus the full credit limit of the new line, divided by the home’s value.

Draw period: The stretch when you can borrow from the line and pay interest only. After it ends, repayment begins.

Bank statement qualification: The line is underwritten on documented deposits rather than tax-return income, subject to lender guidelines.

Seasoning: How long money has sat in your account before a lender treats it as yours.

Reserves: Liquid funds held after closing, commonly measured in months of PITIA (principal, interest, taxes, insurance, and association dues).

What Is the Formula for the Maximum Draw?

The maximum line equals the home’s value times the maximum CLTV, minus the liens already on it. The CLTV counts the entire credit limit, not only what you draw. A line cannot reach 100% of your equity, because the lender always holds back a cushion.

The ceilings depend on how the collateral is used. On an investment-property line, the network ceiling is 70% CLTV, and it is the same at a 700 or a 720 credit profile. Credit above 700 buys eligibility rather than more leverage there. On a primary-residence or second-home line, the ceiling reaches 90% CLTV, but only at 720 or better.

Here is the formula with the dollars stripped out. Say your first mortgage equals half of the property’s value.

Those are ceilings, not promises. The line is the lesser of what equity supports and what the lender’s credit, income, and debt-to-income review allows. Lines run from $25,000 to $750,000, but a line above $500,000 is primary-residence only. It needs a credit profile of 700 or better (720 on the longer-runway structure, covered below), caps at 75% CLTV, and requires a full appraisal.

How Much Purchase Price Can the Draw Support?

The draw supports a purchase price equal to the line divided by your down-payment percentage. Most DSCR purchase files land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV (15% down) with roughly a 700+ score. Each figure is subject to lender guidelines.

Use the shares from the table above. These numbers cover the down payment only, before closing costs and reserves.

Read it like this. A primary-home line at 40% of value can cover the 25% down payment on a rental priced at up to 1.6 times that home’s value. An investment-property line at 20% of value covers the same down payment on a rental priced at 0.8 times its own value. That is why the collateral you choose matters as much as the equity you hold. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

How Does the Bank Statement Part Work?

A bank statement line reads your deposits instead of your tax returns. This helps self-employed owners whose write-offs shrink their taxable income. The lookback is typically 12 or 24 months of statements, set by the program.

The lender totals the deposits and divides by the months in the window to get a monthly figure. Then it removes transfers between your own accounts, loan proceeds, refunds, and refundable security deposits. An expense factor is applied to what remains. Landlords can use rental deposits, but they go through the same screening.

Three points keep the file realistic:

• The line is underwritten on credit, equity, and debt-to-income, not on the rent the new property will earn.
• Debt-to-income has a 50% maximum, and any ratio above 45% requires a credit profile of at least 680. The test uses the interest-only payment on the maximum draw.
• An investment-property line has a 700 credit floor, which is higher than the 680 minimum for business bank account deposits. Because of that, the credit minimum for the deposit analysis is not the binding constraint on that line.

Lendmire is a mortgage broker, not the lender. It places these lines with select wholesale partners, and each lender reviews the full file. The HELOC lines are available in 16 full-service states, which is narrower than the 41-market DSCR footprint.

Two Loans, Two Approvals

You are asking two separate lenders two separate questions. The HELOC lender asks whether you can carry the line. The DSCR lender asks whether the rental can carry its own loan.

The DSCR lender judges the new rental on its own rent against its own payment. Rent is divided by PITIA, and 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.

Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Your line payment sits outside it too.

Will the Purchase Lender Accept the Draw?

Many do with documentation, but the policy splits three ways. Some lenders accept documented line proceeds as down payment. Some cap the borrowed share. The strictest want part of the down payment to be unborrowed. All three show up across the wholesale network, and no one answer applies everywhere.

A fully borrowed down payment can fail on that basis alone. Even where it is allowed, you are financing close to 100% of the price. No DSCR purchase program works with zero down, and a fully borrowed down payment is not the same thing as zero down. The leverage caps, credit floors, reserve rules, and property eligibility still apply. A bigger down payment lowers the loan and can lift the ratio, but it never erases those rules.

Agency loans work differently. Fannie Mae’s selling guidance treats borrowed funds secured by an asset as acceptable for down payment, closing costs, and reserves. That is the agency view only. DSCR programs set their own source-of-funds rules, which is why you ask the purchase lender before you draw.

Three pots get tested separately: down payment, closing costs, and reserves. Borrowed funds are commonly accepted for the first two with documentation. They are often excluded from reserves. Reserves vary by lender, leverage, loan size, and transaction type, and a common expectation is around 6 months of PITIA. Loans above $1,500,000 typically step up to about 9 months.

Some lenders also want the funds to have sat in your own account for a period before they count. Programs differ on that, so ask for the lender’s exact seasoning rule in writing. Also ask whether it wants the HELOC disclosed as a liability. Treat a large unexplained deposit as something you document up front, with the draw statement and the transfer record.

Why Draw Minimums Change How Big the Line Should Be

You can only draw what you open, and you have to draw most of it at the start. On these lines, at least 75% of the line is drawn at closing. After that, each additional draw has a minimum of $1,000 on most files. That means a line sized far above your down-payment need leaves you paying interest on idle cash.

Size the line to the need. Add up the down payment, the closing costs, and the reserves the purchase lender wants from non-borrowed sources. Then open a line where at least three-quarters of it is money you will actually use.

The line also carries its own structure. The pricing floats and never converts to fixed. Primary-home and second-home lines come in two structures. One has a 3-year interest-only draw with a 17-year repayment. The other, the longer-runway structure, has a 5-year draw with a 25-year repayment. Investment-property lines use the 5-year draw and 25-year repayment only. The structure, not just the CLTV, decides your payment when the draw period ends.

The CFPB explains that after a draw period, monthly payments are often significantly higher, and in some cases the whole balance can come due.

Which Line Fits: Primary Home, Rental, or Neither?

The right collateral depends on where your equity sits and what you want to keep. A primary-home line gets the higher ceiling. A rental line is capped lower, and the new property is not collateral for it until you own it.

Title matters here. The line must be held by you as an individual or by a revocable living trust. An LLC, corporation, partnership, or land trust cannot hold title on these lines. A property already deeded to an LLC needs a vesting change, or a rent-qualified DSCR cash-out refinance instead, subject to program terms.

Eligible collateral includes single-family homes, 2-4 units, planned unit developments, townhomes, and condos, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, and commercial or mixed-use properties are not offered. You can hold up to three lines, and a borrower with more than 15 financed properties is not eligible.

What Are the Real Risks of Borrowing the Down Payment?

The main risk is two payments paid from one rent roll. The DSCR ratio can look clean while a second payment sits outside it. The practical test is whether your actual cash flow carries both.

A few other risks deserve a hard look:

• Floating cost. The line payment can rise, and it steps up when repayment starts.
• Collateral. The line is secured by the property it sits on, and the CFPB brochure warns that default can mean foreclosure.
• Thin margin. One BiggerPockets poster says the new property should cash-flow both its own mortgage and the line, and that borrowing the down payment on a long hold means effectively borrowing 100% of the value. That is one investor’s view, but the math behind it holds.
• Return hurdle. The rental’s cash-on-cash return has to beat what the line costs you, or the borrowing loses money.

Exit plans investors describe include paying down the line from rent and savings, retiring it with a cash-out DSCR loan on the new property, or selling a property to clear the balance. A cash-out DSCR loan has its own seasoning and leverage limits, so plan for it before you draw.

Questions to Ask Before You Draw

Run through this list with the purchase lender before you open or draw anything:

1. Do you accept HELOC proceeds as down payment, and is there a cap on the borrowed share?

2. How long must the money sit in my account, and what documents do you want for the draw?

3. Do you count borrowed funds toward reserves?

4. Does the HELOC need to be disclosed as a liability?

5. How much of the down payment must be unborrowed, if any?

Then ask the HELOC side whether the line will be open and drawn before the purchase contract closes. Getting both answers in writing keeps the two approvals from contradicting each other.
