How a Bank Statement HELOC Works on an Interest-Only Rental

The Quick Read: It is a revolving line secured by the rental, qualified on averaged bank deposits instead of tax returns, where the borrower pays only the interest on the drawn balance for five years before a fully amortizing repayment period begins, while equity, credit, and property tests still apply in full.

• The bank statement part changes how income is documented. It does not loosen the equity, credit, or property rules.
• On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a $500,000 maximum line and a 700 minimum credit profile, subject to lender guidelines.
• At least 75% of the line is drawn at closing, so interest starts on most of the line right away.
• Pricing floats and never converts to fixed, so the interest-only payment can move even when the balance does not.
• An LLC cannot hold title on this product. A DSCR cash-out is the usual alternative for entity-owned rentals.

What Is a Bank Statement HELOC on a Rental?

It is a standalone home equity line of credit, in first or second lien position, secured by an investment property and underwritten on deposit history rather than a tax return. Lendmire is a mortgage broker, not a lender. It places these files with select wholesale lenders, which review each file individually and decide eligibility.

Two ideas are bundled into the name. The first is the HELOC itself. You get a credit limit, you draw against it, and the draw period is interest-only. The second is the income method. Instead of W-2s or a Schedule C that shows write-offs, the underwriter reads 12 or 24 months of bank statements and averages the deposits into monthly income.

That second idea is why self-employed landlords look at this product. Their returns often understate real cash flow. The deposits tell a fuller story.

Key Terms Defined

• Draw period: the stretch of time you can borrow against the line and pay interest only. On an investment line in this network, it runs five years.
• Repayment period: the phase after the draw ends, when borrowing stops and payments include principal. On investment lines it runs 25 years, fully amortizing.
• CLTV: all liens on the property, plus the new line, divided by the property’s value.
• DTI: your monthly obligations divided by your qualifying monthly income.
• Qualifying payment: the interest-only payment calculated on the maximum draw, used to test DTI.
• Expense factor: the percentage of business-account deposits an underwriter treats as operating cost rather than income.

How Underwriting Treats It, Step by Step

Underwriting follows a predictable order. Each step must clear before the next one matters.

1. Title. The property must be held by you personally or by a revocable living trust. This gate comes first because it cannot be fixed with paperwork later.

2. Income from deposits. The underwriter pulls 12 or 24 months of personal or business statements. Transfers between your own accounts, loan proceeds, and owner capital injections come out. Business-account deposits then take an expense factor. Each lender sets its own lookback period and expense defaults, so no single formula applies across the network.

3. Credit. Investment lines require a 700 minimum. The score comes from a single bureau, keyed to the primary wage earner, and the report can be no more than 90 days old at closing.

4. DTI. The ceiling is 50%. The test uses the interest-only payment on the maximum draw, not the amount you plan to use.

5. CLTV. Investment lines top out at 70%. Both the 700 and 720 credit tiers reach the same 70%, so a higher score buys eligibility, not extra leverage.

6. Valuation. Lines at or below $500,000 ordinarily use an automated valuation. An investment line can never exceed $500,000, so it sits in that lane. A higher CLTV may call for a secondary valuation, and a borrower may always request a full appraisal.

7. Property. Single-family, 2-4 unit, PUD, townhome, and condominium (including non-warrantable) properties are eligible. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural-zoned properties are not offered.

Here is how the equity test plays out in percentages. Say a rental’s existing first mortgage sits at 50% of its value. Under a 70% CLTV ceiling, the new line can use roughly the remaining 20 points of value, still capped at the $500,000 maximum. A property with a bigger first mortgage leaves less room, however strong the deposits look.

Business bank accounts carry a 680 minimum for the deposit analysis. Investment files already floor at 700, so the deposit analysis is never the binding constraint here. Credit and equity are.

Where Rent Fits (and Where It Doesn’t)

This is the point many borrowers get wrong. The product is reviewed around the borrower on deposits and DTI. It does not qualify the property on rent covering its payment.

Rent you collect may show up in your deposits, depending on which account receives it. That helps your averaged income. It does not turn the line into a rent-coverage loan. A DSCR loan works the other way: it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

The difference matters when a rental sits vacant. The line’s interest-only payment is still counted in your DTI, and still due, whether or not a tenant is paying.

What You Pay During the Interest-Only Phase

During the draw period, the payment equals the interest accruing on the drawn balance. You do not pay on the unused part of the line. The Federal Trade Commission notes the same thing for HELOCs generally: you pay interest on what you borrow, not on the full available line.

Two features of this network’s investment line change the picture.

The opening draw is required. At least 75% of the line must be drawn at closing. Think of it as a funded loan with a reborrowing option, not a dormant safety net. Interest starts on most of the line on day one.

Pricing floats. It floats through both the draw and repayment periods and never converts to fixed. The CFPB’s HELOC booklet warns that on variable plans the payment may change even if you borrow nothing more.

Interest-only also means the balance does not shrink. Optional principal paydown is generally allowed, and it is the simplest way to lower the cost of carrying the line. After closing, later draws typically carry a $1,000 minimum.

Qualifying Payment vs. Actual Payment

The gap runs one way. Because the test assumes a full draw, a borrower can qualify on a payment larger than the one they actually make. The reverse trap is the opening draw. With 75% drawn at closing, the actual payment starts close to the qualifying payment.

What Happens When Interest-Only Ends

On an investment line, the five-year draw ends and the 25-year repayment period begins. Borrowing stops. The payment now includes principal, and the balance amortizes fully, with no balloon.

Experian reports that payments often more than double when a draw period ends compared with the interest-only stage. That is a market-wide observation, not a network promise. Still, the mechanics explain why. The same balance now has to repay principal over a finite term.

The practical timeline looks like this:

1. Closing. Most of the line is drawn. Interest begins.

2. Years one through five. Interest-only payments on a floating price. Optional paydowns are available, and the line can be reborrowed.

3. Year five. Borrowing ends. Payments step up.

4. Years six through thirty. Principal and interest on a fully amortizing schedule.

Plan the step-up before year five. Rents should be able to carry a payment that is substantially higher. Otherwise, line up a paydown, a refinance, or a sale ahead of time.

Where the General Rule Breaks

Several edge cases change the answer.

Entity-owned rentals. Title must sit with the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out structured subject to lender program eligibility.

Large portfolios. A borrower can hold up to three lines, with combined exposure capped at $750,000 on this investment structure. Anyone with more than 15 financed properties is not eligible.

Seasonal or lumpy deposits. A 12-month window can capture a strong season and overstate income, or a weak one and understate it. A 24-month window smooths the swings but can drag the average down if your recent months are your best. Businesses younger than 24 months often get alternative weighting.

Recent derogatory credit. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure history on investment files follows a seven-year path, and a deed-in-lieu, pre-foreclosure, or short sale follows four.

Falling values. The CFPB notes that a lender may restrict further credit if the home’s value drops significantly. A reborrowing plan built on future draws can be interrupted.

Product availability. These lines are brokered in Lendmire’s 16 full-service states, a narrower footprint than its DSCR platform, which covers 41 markets including Washington, D.C.

Bank Statement Line vs. a DSCR Cash-Out

The two products solve similar problems with different tests.

A DSCR cash-out has no revolving feature. It also typically expects about six months of seasoning. In exchange, it measures the property rather than your deposits, and it can fit larger portfolios.

The 1.00 coverage mark is where many select DSCR programs start, and stronger ratios open better pricing and leverage. Clearing it is not the same as positive cash flow, since repairs, vacancy, management, and capex sit outside the calculation. A separate select-lender path goes below 1.00, with leverage and terms adjusted.

Is It the Right Tool? A Self-Assessment

The product tends to fit when three things are true.

• Your returns understate your cash flow. Deposits tell a stronger story than your tax return.
• You hold the property personally, or can move it into your name or a revocable trust.
• You have an exit plan for the day the draw ends: a paydown, a refinance, or a sale.

It tends to fit poorly when the rental depends on thin coverage, when a vacancy would strain your reserves, or when you plan to hold the balance for decades without paying it down. In that case, a fully amortizing loan from the start may be the more honest choice.

Documentation Checklist

• 12 or 24 months of personal or business statements, matched to the account that receives your income
• A clear record of which deposits are transfers, loan proceeds, or owner contributions
• Proof of vesting: a deed in your name or a revocable trust
• Credit that is current, with a report under 90 days old at closing
• A list of all financed properties and existing liens, so CLTV can be calculated

Before the statement window, avoid large unexplained deposits and moving money between accounts. Underwriters strip those out, and a messy history lowers the average.
