How a Bank Statement HELOC Works on a Fourplex With Five Financed Rentals

The Quick Read: A bank statement HELOC on a fourplex is a revolving line secured by the building and qualified on your documented deposit income under the applicable program, subject to lender guidelines; the fourplex’s rent does not size it, but your other financed rentals count against your debt load, and the building must pass equity, title and property tests. In short, the deposits are the income and the building is only the collateral.

• On an investment property, this network’s ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a maximum line of $500,000.
• Title must sit with you personally or in a revocable living trust. An LLC cannot hold it.
• Debt-to-income (DTI) tops out at 50%, tested on the interest-only payment at the maximum draw.
• Five financed rentals is not a disqualifier on this network. The limits are three lines per borrower and no more than 15 financed properties.
• Whether the fourplex is one of your five or a sixth, it generally counts as one property.

What Is This Line, and What Secures It?

A bank statement HELOC is a revolving line of credit secured by your fourplex, qualified on deposits rather than tax returns. It is a standalone line that can sit in first or second lien position. If you already have a mortgage on the building, the line usually sits behind it, and your existing loan stays untouched.

That second-lien feature is the main appeal. A cash-out refinance replaces your first mortgage. A line leaves it alone. If your current first mortgage has terms you would hate to give up, that matters.

Here is how the pieces fit on the building in this title:

• The collateral: a two- to four-unit building. A fourplex sits at the top of the eligible range. Five or more units is commercial, and mixed-use is not offered on this line. Appraisal-industry guidance draws the same line, treating one to four units as residential and five or more as a different standard.
• The income: your deposits, not the building’s rent roll.
• The other four rentals: they never touch the collateral math, but they weigh heavily in your debt picture.

This product is the opposite of a DSCR loan. On a DSCR loan, the property’s rent drives the decision. On this line, your documented deposits drive the income test, and the fourplex only has to pass the collateral tests.

How Underwriting Treats Bank Statement Income

Underwriters read your actual deposits over a set window, strip out anything that is not true income, and average what remains. The window is commonly 12 or 24 months, and the specific program sets it. The steps run in a predictable order.

1. Choose the statement type. Personal accounts, business accounts, or both can be used, depending on the program.

2. Scrub the deposits. The underwriter removes transfers between your own accounts, loan proceeds, refunds and one-time credits. What is left is treated as income.

3. Apply an expense factor on business accounts. The lender sets this factor, not you. It depends on the type of business and similar variables. No standard percentage applies across programs, so any number you hear online is a guess about someone else’s file.

4. Average over the window. That average becomes your monthly qualifying income.

5. Test your debts against it. This is where five financed rentals matter most, and the next section covers it.

Two practical points deserve attention. First, a business account needs a 680 minimum for the deposit analysis. Investment lines on this network already require a 700 minimum credit score, so the bank statement piece is never the binding constraint on credit. Second, rental income that lands in your accounts is a judgment call. Programs differ on whether it counts as personal income or as property income. Keep rent in a clearly labeled account, and keep leases that match the deposit trail.

Bank statements change how your income is documented. They do not raise your leverage. The same 70% CLTV ceiling and 700 credit floor apply on an investment property whether you document with tax returns or deposits.

What Do Five Financed Rentals Actually Change?

Five financed rentals change your borrower-level tests but not the building’s collateral tests. Property-level checks look only at the fourplex: its value, its liens, its title and its type. Borrower-level checks look at you: credit, DTI, payment history and total exposure.

Caption: the building passes or fails on its own; you pass or fail on everything you owe.

A fourplex is one property, with one title, one lien stack and one collateral test. It is not four loans. More units add paperwork, such as leases and a matching deposit trail, but they do not create a new formula.

The count limits on this network are generous for a five-rental investor. A borrower can hold up to three lines, and anyone owning more than 15 financed properties is not eligible. Five rentals sits well inside that range. Whether the fourplex is one of your five or a sixth, it generally counts as one financed property, and the program review confirms how it is tallied. Many large retail lenders set their own, tighter caps on financed investment properties, so a decline there does not predict an answer from the wholesale network.

How Is the Line Sized on a Fourplex With Five Loans?

The line limit is the CLTV ceiling times the building’s value, minus every lien already on that building, capped at $500,000. Nothing about the other four rentals enters this subtraction. Their balances belong to the DTI test.

Run the collateral math in percentages. These are modeled assumptions, not market data.

• CLTV ceiling on an investment property: 70%.
• Existing first mortgage on the fourplex: assume it sits at 55% of value.
• Room left for the line: about 15 points of value.

If the first mortgage sits at 40% of value, the room grows to about 30 points, and the $500,000 cap may bind first on a large building. If you bought the fourplex recently with a high-leverage first mortgage, there may be no room at all until paydown or appreciation creates it. CLTV is commonly measured on the full line amount, not only what you draw. At least 75% of the line is drawn at closing in any case.

Now run the income side with another modeled assumption.

• Maximum DTI: 50%.
• Debts already counted: the five rentals’ mortgages, taxes and insurance, plus your personal debts. Assume these take about 38% of your qualifying deposit income.
• Room left for the new line: about 12 points.

The new line is tested on the interest-only payment at the maximum draw, not on what you plan to borrow. A borrower who intends to draw a little still gets tested as if they drew it all. That is why strong deposits and a modest existing debt load matter more than the building’s rent.

For a fully rented building, the valuation usually runs through an automated model. Lines at or below $500,000 ordinarily skip a traditional appraisal. Investment lines cap at $500,000, so they sit in that lane, though a higher CLTV may call for a secondary valuation and you can always request a full appraisal. When a full appraisal is ordered on a two- to four-unit building, the appraiser uses the multi-unit form, which includes its own rent-comparable section.

Title and Vesting: The First Gate

Title is the first gate, and it stops many investors before any math starts. The fourplex must be held in your individual name or in an inter vivos revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title for this line.

Many investors hold rentals in LLCs, so this matters. If your fourplex is already deeded to an LLC, you have two options. You can change the vesting, which has consequences you should review with your attorney and your existing lender. Or you can skip this product and use a DSCR cash-out refinance instead, subject to lender program eligibility. That route accepts entity-held property because it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Where the Rule Breaks: Edge Cases

The general rule is that deposits plus equity plus clean title gets you a line. A handful of situations bend it.

• Live in one unit. Occupancy changes the classification from investment to primary residence. Primary-residence ceilings are higher, reaching 90% CLTV only at a 720-or-better credit profile. Lines above $500,000 are primary-residence only, with at least a 700 profile, a 75% CLTV cap and a full appraisal. Confirm the occupancy tier in the guidelines before you plan around a number.
• Freshly bought fourplex. A recent purchase often leaves no CLTV room, so the line may have to wait.
• Property listed for sale. A building listed now, or within the past 60 days, is ineligible in several states.
• Five or more units. The building leaves this product entirely.
• Manufactured homes, log homes, barndominiums, condotels and mixed-use. These are not offered.
• Vacant unit during review. A vacancy does not change the deposit math directly, but it can hurt the story your deposits tell if rent was part of your income.
• State availability. This line is available only in 16 full-service states, which is narrower than the 41-market DSCR footprint.
• Past credit trouble. A bankruptcy needs four years of seasoning from discharge or dismissal. On an investment file, a foreclosure needs seven years, and a deed-in-lieu, pre-foreclosure or short sale needs four.

How Do the Draw and Repayment Periods Work?

The line works in two phases. During the draw period you borrow, repay and borrow again. In repayment, the line stops revolving and you pay it off.

The CFPB describes a HELOC as an open-end line of credit that you can draw on repeatedly. It also notes that a lender may refuse further draws if the property’s value drops significantly. Its consumer booklet warns that payments can rise once repayment begins.

On this network, investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Pricing floats through both periods and never converts to a fixed structure. After closing, the minimum subsequent draw is typically $1,000. Because the payment steps up when repayment starts, model that jump before you draw for a purchase.

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

Bank Statement HELOC or DSCR Loan?

Pick the product that matches your weak point. If your deposits are strong but the fourplex’s rent is thin, the HELOC may fit better. If the fourplex cash flows well but your deposits are messy, a DSCR loan may fit better. If your title is in an LLC, DSCR is usually the straightforward route.

Caption: the HELOC reads you; the DSCR loan reads the building.

On a DSCR loan, the lender compares monthly rent to the full monthly obligation: principal, interest, taxes, insurance and any dues. Many select programs start at a 1.00 coverage floor. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management and capital costs sit outside the calculation. The complete DSCR loans guide walks through that math.

Many borrowers combine both products. The line funds a down payment, and a separate DSCR loan buys the next building.

What Should You Gather Before You Apply?

A multi-rental borrower should bring more than the collateral file. Gather these items:

• Twelve or 24 months of statements for each account you want counted.
• A schedule of all five financed properties with each mortgage statement.
• Leases and a rent roll for the fourplex, matched to your deposits.
• Proof of how the fourplex is titled.
• The current first-mortgage balance on the building.
• Insurance details on every property.
