The Quick Read: A duplex where you occupy one unit is generally treated as an owner-occupied primary residence, so a self-employed owner can often qualify for an equity line on documented deposits, though the lenders that write it are mostly specialty wholesale lenders rather than large retail banks.
Occupancy, title, and equity decide whether the line works, because bank statements change only how income is documented, not how the line is sized.
- Lender type: this product comes mainly from non-bank and portfolio lenders, and the right fit depends on credit profile, leverage need, and property.
- Occupancy: living in one unit puts the duplex in the primary-residence tier. Renting every unit moves it to the investment tier, with lower leverage and a higher credit floor.
- Title: the individual borrower or a revocable living trust can hold title. An LLC cannot.
- Sizing: the line is capped by combined loan-to-value, so the first mortgage balance counts against it.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
How Does a Bank Statement HELOC Work on a Duplex?
A bank statement HELOC is a revolving line secured by your home, where the lender calculates qualifying income from 12 to 24 months of deposits instead of tax returns. The duplex adds one question: how the lender classifies the building. That answer sets the leverage, the credit floor, and the documents.
Two structural pieces are fixed. The collateral side is ordinary: the lender adds the first mortgage and the new line, divides by the appraised or estimated value, and compares the result to a combined loan-to-value (CLTV) ceiling. The income side is the part that bends. Personal or business statements are reviewed, non-income deposits such as transfers, loan proceeds, and refunds are removed, and an expense factor is applied to business accounts, with the factor set by the program.
The line is still fully underwritten. Credit, debt-to-income, CLTV, and the property all get reviewed. The phrase to remember is that the borrower is reviewed on documented income under the applicable program, subject to lender guidelines.
Does Living in One Unit Make It Owner-Occupied?
In most programs, yes. Living in one unit of a two-to-four-unit building generally classifies it as owner-occupied for lending purposes, and the other unit’s tenant does not change that. BiggerPockets describes this house-hacking setup as living in one unit and renting the other, and notes that owner-occupied loans typically expect you to live in the home for one year.
The classification matters because the network’s equity-line ceilings are tiered by occupancy:
| Factor | Live in one unit | Rent every unit |
|---|---|---|
| Occupancy class | Primary residence | Investment property |
| Max CLTV | Up to 90% at 720+ credit | 70% at 700+ credit |
| Min credit | 600 program floor | 700 hard floor |
| Max line size | Up to $750,000 | Up to $500,000 |
| Draw structure | Two options | 5-year draw, 25-year repay |
The 90% ceiling exists only for primary residences and second homes at a 720-or-better credit profile. Lower tiers sit below it. On the investment side, 720 and 700 both reach 70% CLTV, so a score above 700 buys eligibility, not extra leverage.
Claiming owner-occupancy on a building you do not live in is misrepresentation. If the plan is to move out within the year, the file belongs in the investment tier, or the better tool may be a DSCR loan.
Which Banks Offer This? (The Honest Answer Is a Category)
Few large retail lenders advertise a bank statement line on a duplex. Most large depositories write standard-documentation lines on owner-occupied one-to-four-unit homes and want W-2 or tax-return income. Bank statement lines come mainly from non-bank and portfolio lenders, and each of those writes a different slice of the market.
Lendmire is a mortgage broker, not a lender, so it does not rank or recommend a lender. It places these files through select wholesale partners. The right program for your situation depends on property type, credit profile, how much leverage you need, and how your income is documented. A broker that shops several wholesale lenders can match the scenario to the program whose overlays fit it, instead of sending you to the one product a single institution happens to sell.
One availability point matters before anything else. Lendmire’s equity-line placements run in 16 full-service states, which is narrower than its 41-market DSCR footprint, which covers 40 states plus Washington, D.C. Confirm that your state is in the footprint before you build a plan around the line.
How Underwriting Treats the File, Step by Step
1. Classify occupancy. The lender confirms which unit you occupy and that you will stay. This picks the program tier from the table above.
2. Verify title and vesting. Title must sit with the individual borrower or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines.
3. Pull credit. The network uses a single-bureau score keyed to the primary wage earner, with a report no more than 90 days old at closing and no rescores. The program floor is 600, and housing-history standards apply across all financed properties.
4. Calculate income from deposits. The underwriter totals qualifying deposits across the statement window, removes non-income items, and applies the program’s expense factor where it applies. Business bank accounts need a 680 minimum for the deposit analysis, which sits above the 600 program floor. An investment line already floors at 700, so the deposit analysis is never the binding constraint there.
5. Layer in the second unit’s rent. Rent from the other unit is usually a separate line, documented with a lease or rent roll. Treatment varies by program. The key point is that an equity line is underwritten on personal credit and debt-to-income, not on how well the property’s rent covers its payment.
6. Test DTI. Maximum DTI is 50%, but profiles from 600 to 679 are held to 45%. Going above 45% therefore requires a score of at least 680. The payment used is calculated on the interest-only amount at the maximum draw, not on a smaller balance.
7. Size the line against CLTV. The first mortgage balance plus the line divided by value must sit inside the ceiling for the occupancy and credit tier.
8. Value the property. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal, though a higher CLTV may require a secondary valuation. Every line above $500,000 needs a full appraisal, and a borrower may request one in any case.
9. Close with the standard disclosures. An equity line on your home carries consumer protections. The CFPB explains the open-end structure, including a draw period followed by a repayment period, and notes that some plans require an initial draw or a minimum outstanding balance.
What Does the Line Itself Look Like?
The network places standalone lines in first or second lien position, in sizes from $25,000 to $750,000 (Michigan’s floor is $10,000). There are two draw structures on primary residences and second homes. One runs a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other runs a 5-year draw followed by a 25-year repayment. Tennessee shortens both. Investment lines run the 5-year draw and 25-year repayment structure only.
At least 75% of the line is drawn at closing, and pricing floats through both the draw and repayment phases without converting to fixed. After closing, the minimum subsequent draw is generally $1,000, with Texas higher. The 75% initial draw has a practical effect: this is not a standby line you open and leave empty, so the borrower should plan for the drawn balance from day one.
A line above $500,000 is for primary residences only. It requires a score of 700 or better (720 on the longer-runway structure, the one with the 5-year draw and 25-year repayment), caps at 75% CLTV, and requires a full appraisal. A borrower may hold up to three lines, and combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible.
A Worked Example in Percentages
Take a self-employed owner who lives in one unit of a duplex, has a 720-plus credit profile, and owes about 55% of the property’s value on the first mortgage. The primary-residence ceiling of 90% CLTV leaves room for a line of up to roughly 35% of value, before DTI and the line-size caps are applied.
Now run the same duplex with every unit rented and the owner living elsewhere. The investment ceiling is 70% CLTV, so the same first mortgage leaves room for a line of roughly 15% of value. The credit floor also rises to 700, and the line cannot exceed $500,000.
That gap is the reason occupancy classification is the first step on every file. The same building, the same borrower, and the same first mortgage produce very different capacity depending on how it is occupied.
Two limits keep this honest. Equity room is not guaranteed room, because debt-to-income can bind before CLTV does. And a borrower should not size the line to fund an entire down payment on the next property, since that leaves the whole purchase leveraged against the home they live in. An investor discussion on BiggerPockets makes the same two points: get the line while the property is still owner-occupied, and do not finance every dollar of the next purchase with it.
Where the Rule Breaks
The owner-occupied duplex line is a clean fit until one of these shows up.
LLC title. If the duplex is already deeded to an LLC, an equity line is not an option, because an LLC cannot hold title. The practical routes are a vesting change into your name or a revocable trust, or a DSCR cash-out refinance that is available to entity-held rentals, subject to program terms.
Fully rented building. The occupancy class flips to investment. Leverage drops to the 70% CLTV tier, and the credit floor goes to 700.
Mixed-use buildings. A duplex with a commercial or storefront unit is not eligible, because commercial, mixed-use, and agricultural-zoned properties are not offered.
Five or more units. The network’s equity programs cover single-family and two-to-four-unit properties. A larger building is a different product.
Unpermitted units. An illegal or unpermitted second unit can fail the valuation or the property review.
Rental restrictions. The CFPB’s open-end credit materials place home-equity lines outside the ability-to-repay rule for closed-end mortgages, and that rule’s scope covers one-to-four-unit dwellings. That is why the lender, not a federal rule, sets how income is verified, and why the bank statement option exists only where a lender chooses to offer it. It also means the line’s own terms can restrict renting out the home, so check how it treats a tenant in the other unit.
Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington.
Manufactured and log homes. Manufactured homes, log homes, and barndominiums are not offered. Co-ops and condotels are also out. Modular factory-built homes are eligible on the longer-runway program only.
Bank Statement HELOC, DSCR Loan, or Cash-Out Refinance?
The three tools solve different problems, and many self-employed investors use more than one.
| Factor | Bank statement HELOC | DSCR loan | Cash-out refinance |
|---|---|---|---|
| Reviewed on | Personal deposits | Property rent vs. PITIA | Varies by program |
| Fits | Home you live in | Rental property | Replaces first mortgage |
| Title | Individual or revocable trust | LLC possible, per program | Varies |
| Keeps first mortgage | Yes | Not applicable | No |
| Leverage cap | 90% CLTV at 720+ (primary) | 75% on cash-out | Varies |
A DSCR loan compares the property’s rent to its full monthly obligation of principal, interest, taxes, insurance, and any HOA dues. Coverage of 1.00 is where select programs start, and stronger ratios open better terms and leverage. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. DSCR cash-out refinances top out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
One caution applies to any coverage ratio: clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex sit outside the calculation. Lendmire’s complete DSCR loans guide walks through how that ratio is built and where it stops being informative.
In practice, the owner-occupied duplex is where the equity line fits. Once the next purchase is a rental held in an LLC, the DSCR loan is usually the better tool. Lendmire’s piece Banks That Offer a Bank Statement HELOC Without traditional Income Documentation covers the documentation side in more detail, and its article Banks That Offer a Bank Statement HELOC Without Tax Returns for a Primary or Second Home covers the non-investment tiers.
What to Have Ready Before You Apply
A short checklist keeps the file from stalling on missing pieces:
- Consecutive personal or business bank statements covering the program’s window, with every page included.
- A current first-mortgage statement showing the payoff balance.
- Proof of title: a deed or vesting document showing you or your revocable trust, not an entity.
- A lease or rent roll for the second unit, if you want that rent considered.
- Homeowners insurance for the full building.
- A credit profile that has not been recently pulled outside the 90-day window, since no rescores are allowed.
- A clear answer on occupancy: which unit you live in and how long you plan to stay.
Questions worth asking any broker or lender before applying: which tier the duplex falls into, whether title needs to change, which draw structure applies, whether the program requires the 75% initial draw, and whether the valuation will be automated or a full appraisal.
Key Terms Defined
Bank statement income: qualifying income calculated from actual deposits over a set window rather than from tax returns.
Owner-occupied: a property where the borrower lives in at least one unit as a primary residence.
CLTV: combined loan-to-value, which is the first mortgage plus the new line divided by the property’s value.
Expense factor: a program-set percentage subtracted from business deposits to estimate income after operating costs.
Second lien: a loan secured behind an existing first mortgage, which is the position many equity lines take.
Draw period: the stretch of years when you can borrow against the line, followed by a repayment period.
Frequently Asked Questions
Can I get a bank statement HELOC on a duplex if I live in one unit?
Often, yes, subject to lender guidelines. The duplex generally counts as a primary residence, and two-to-four-unit properties are eligible, though the longer-runway program requires a 640 minimum score for them. Credit, DTI, CLTV, and the property still get reviewed.
What is the most I can borrow?
Lines run from $25,000 to $750,000, and the amount is capped by CLTV. On a primary residence the ceiling reaches 90% CLTV only at a 720-or-better credit profile. A line above $500,000 is primary-residence only, needs 700 or better (720 on the longer-runway program), caps at 75% CLTV, and needs a full appraisal.
What happens if I rent both units?
The property moves to the investment tier. The ceiling is 70% CLTV with a 700 credit floor, the maximum line is $500,000, and the 5-year draw and 25-year repayment structure is the only one available. Because the line cannot exceed $500,000, it ordinarily uses an automated valuation instead of a traditional appraisal, though a borrower may request a full appraisal.
Can my LLC hold title to the duplex?
No. Title must be held by the individual borrower or an inter vivos revocable living trust, so a property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
Is this the same as a DSCR loan?
No. An equity line is reviewed on personal deposits and credit and fits the home you live in. A DSCR loan is reviewed primarily on property-level rental income covering the payment and fits the rentals.
