How a Bank Statement HELOC Works on a Duplex or Fourplex

The Quick Read: A bank statement HELOC is a revolving credit line, secured by your building, that is reviewed on your own deposits instead of tax returns. Lenders approve the borrower and the equity, not the rent the building collects. On a two- to four-unit property, the line is reviewed as a primary residence if you live in one unit and as an investment property if you rent every unit. That one classification sets your credit minimum, your leverage ceiling, and your maximum line size.

• On an investment property, the ceiling in Lendmire’s wholesale network is 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a line of up to $500,000.
• On a primary residence, the ceiling reaches 90% CLTV only at a 720 or better credit profile.
• Title must sit with you personally or in a revocable living trust. LLC-held buildings cannot use this product.
• Qualifying income comes from your eligible deposits over a set lookback window, not from the building’s rent.
• The structure is a draw period followed by a repayment period, and the cost of the line floats.

Every figure here is subject to lender guidelines and full file review. This is not a commitment to lend.

Key Terms Defined

HELOC: a home equity line of credit, a revolving loan that lets you borrow against equity in steps.

CLTV: combined loan-to-value, which adds your first mortgage and the new line together and divides by the property’s value.

Bank statement income: qualifying income that a lender calculates from your eligible deposits over a set lookback window.

Draw period: the stretch when you can borrow from the line, usually followed by a longer repayment period.

Vesting: the legal name that holds title to the property.

What a Bank Statement HELOC Is

It is a standard equity line with a different income document. The collateral is your duplex or fourplex. The qualifying income comes from your bank deposits rather than a tax return.

That difference matters for owners of rental buildings. Depreciation, repairs, and other write-offs shrink the income on a tax return. Your deposits can tell a truer story. The documentation is alternative, not absent. You still prove income, credit, equity, and property eligibility.

Across the wholesale network Lendmire brokers through, this product is a standalone line in first or second lien position. Your existing first mortgage can stay in place. The line sits behind it. Lendmire arranges the file through select wholesale partners and is never the lender.

The product is offered in Lendmire’s 16 full-service states, a narrower footprint than its DSCR lending. Eligibility depends on where the property sits.

How Underwriting Treats the File, Step by Step

1. Classify the occupancy. The reviewer decides whether the building is your primary residence, a second home, or an investment property. Everything downstream depends on this.

2. Confirm property eligibility. Two- to four-unit residential buildings are eligible. Mixed-use, commercial, and agricultural-zoned properties are not.

3. Pull the statements. The program sets a lookback window of personal or business statements. You do not choose it.

4. Clean the deposits. Underwriters strip out transfers between your own accounts and credits that are not income. Raw deposits are never simply added up.

5. Apply the expense factor on business accounts. The lender treats a share of gross business deposits as operating cost. The program sets that share, and it varies. Personal-account deposits generally skip this step.

6. Average to a monthly figure. Eligible deposits, after the factor and your ownership share, are averaged over the months reviewed.

7. Test the debt-to-income ratio. The maximum is 50%, and 45% for credit profiles from 600 to 679. A ratio above 45% requires a 680 minimum. The test uses the interest-only payment calculated on the maximum draw.

8. Check credit, equity, and title. The credit report must be no more than 90 days old at closing. CLTV and vesting are reviewed alongside it.

Business bank accounts need a 680 minimum for the deposit analysis. An investment line already floors at 700, so deposit analysis is rarely the binding constraint on an investment file. The binding constraints are leverage and title.

The line itself is open-end credit. The CFPB explains that you can borrow repeatedly during the draw period, then enter a repayment period when borrowing stops. Pay attention to what happens in that second phase, because the payment can change when the draw period ends.

Live in One Unit or Rent All of Them

Occupancy is the biggest lever on the file. A fully rented building is an investment property. A building where you live in one unit is generally a primary residence. The two classes run on different tables.

The 90% figure exists only at a 720 or better credit profile. A line above $500,000 is primary-residence only, needs a 700 or better credit profile (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal. Lower credit tiers sit below those ceilings.

If you move out and rent every unit, the line is reviewed as an investment property. Read the occupancy covenants in your line agreement before converting a unit to a rental. Some lines restrict renting the home out.

The Leverage Math on an Investment Line

Investment properties have a two-tier table. A 720 score and a 700 score both reach 70% CLTV. Credit above 700 buys eligibility, not extra leverage.

Run the numbers on a fully rented fourplex, in percentages. Say your first mortgage equals 50% of the building’s value. A 70% CLTV ceiling leaves room for a new line of about 20% of value. If your first mortgage already equals 65%, only about 5% of value remains. The line may not be worth pursuing.

An existing first mortgage uses up leverage room fast on a multi-unit building. The $500,000 cap and the 70% ceiling both apply, and the smaller of the two controls.

Valuation on these lines is simpler than many owners expect. Because an investment line caps at $500,000 and full appraisals begin above that level, the file typically runs on an automated valuation. A traditional appraisal is not usually part of the process, though you may request one.

Structures and Variations

Investment lines run one draw structure: a five-year interest-only draw followed by a 25-year fully amortizing repayment. On primary residences and second homes, a three-year draw with a 17-year repayment is also available. At least 75% of the line is drawn at closing. After closing, the minimum subsequent draw is typically $1,000.

The cost of the line floats during both the draw and repayment periods and never converts to fixed. That is a real risk on a rental building. A line that is mostly drawn up front, with a changing payment, deserves a stress test against your rents.

Line size runs from $25,000 to $750,000. Exposure limits apply across your whole portfolio. You are limited to three lines. An owner of more than 15 financed properties is not eligible.

Where the General Rule Breaks

LLC-owned buildings. Title must be held by you or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A building already deeded to an LLC needs a vesting change, or a different loan altogether. Moving title can have its own consequences, so think through the effect on your first mortgage and insurance first.

Five or more units. That is commercial lending, and it falls outside this product. A fourplex is still residential.

Mixed-use buildings. A storefront below apartments is not eligible.

Short-term rentals. NerdWallet reports that some lenders restrict investment-property lines by location and by whether the home is rented year-round. Short-term rental rules can vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.

Buildings under renovation. Equity is thin and an automated valuation cannot see unfinished work. A line on a mid-rehab building is usually impractical.

Recently listed properties. In NC, PA, TN, TX, and WA, a property listed for sale within the past 60 days is ineligible.

Commingled accounts. Rent deposited into a personal account that also pays your groceries muddies the deposit analysis. Treatment of personal versus business accounts differs by program. Clean separation helps the file.

Manufactured homes and similar types. Manufactured homes, co-ops, condotels, and log homes are not offered.

Credit history events. A bankruptcy needs four years of seasoning from discharge or dismissal. Investment files follow a seven-year path for a foreclosure and four years for a deed-in-lieu, pre-foreclosure, or short sale.

Availability is the broader catch. NerdWallet notes that not every lender offers a line on an investment property and that requirements are strict. A broker with several wholesale lenders can match your file to the program that fits it.

Bank Statement HELOC or DSCR Loan

These two products solve different problems. A bank statement HELOC tests you. A DSCR loan tests the building.

A DSCR loan compares monthly rent to the full property payment: principal, interest, taxes, insurance, and any association dues. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire arranges DSCR lending across 41 markets, including Washington, D.C.

A DSCR cash-out refinance tops out around 75% LTV across most of the network, with about six months of seasoning as the common expectation. The coverage floor starts at 1.00 on select programs, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Clearing that ratio does not mean positive cash flow. Repairs, vacancy, management, and capital expenses sit outside the calculation. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Choose whichever document set is stronger. If your deposits are strong, the line may fit. If your rent is strong or your building sits in an LLC, DSCR is usually the cleaner path. For the full picture, read the complete DSCR loans guide.

What the Decision Looks Like in Practice

An owner living in one unit of a duplex. The file runs on the primary-residence table. Credit and equity carry the decision. This is the owner with the most room, because ceilings reach higher, though only at a 720 profile.

An owner who rents every unit of a fourplex personally. The file runs at 70% CLTV with a 700 minimum. The question is how much equity remains after the first mortgage.

An owner whose fourplex sits in an LLC. This product is out unless title moves. A DSCR cash-out refinance, subject to lender program eligibility, may fit better.

A line does not buy a property. It funds a down payment or a rehab. A separate purchase loan buys the next building, and a DSCR purchase typically lands at 75% to 80% LTV on most files. Lendmire’s article Best Bank Statement HELOC Program on a Duplex, Triplex or Fourplex explains how the best program depends on your property, credit, and goals.
