The Quick Read: The best program for your situation depends on your credit profile, the equity in the building, and how much you need to draw. A duplex you live in is treated as a primary residence, which unlocks the highest leverage tier on the network, subject to lender guidelines.
- Living in one unit makes the duplex a primary residence for pricing, and that tier reaches 90% CLTV only at a 720-or-better credit profile.
- Primary-residence lines can run up to $750,000, but anything above $500,000 needs a full appraisal and a credit profile of 700 or better (720 on the longer-runway structure).
- The duplex must be held in your own name or a revocable living trust. An LLC cannot hold title.
- Your first mortgage stays in place. The line sits beside it, in first or second position.
- Rent from the other unit is not a shortcut around a thin income profile.
Lendmire is a mortgage broker, not a lender. It places these files with select wholesale partners, so the program that fits is matched to your scenario rather than assumed in advance. This product is available only in Lendmire’s 16 full-service states, which is narrower than its DSCR footprint.
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.
What Is a Bank Statement HELOC on a Duplex?
A bank statement HELOC is a home equity line that measures a self-employed borrower’s income from deposits instead of tax returns. A duplex you live in qualifies as a primary residence. The line is an open-end credit product, not a closed-end mortgage.
The Consumer Financial Protection Bureau describes a HELOC as a line of credit against the value of your home minus what you owe. It has a draw period, then a repayment period. Payments follow the outstanding balance.
Two things follow from that. First, “bank statement” is a documentation choice by the lender, not a legal category. Second, the product is built for owners whose tax returns understate what they actually earn. Heavy write-offs are the classic reason.
On this network, the line is a standalone product in first or second lien position, sized from $25,000 to $750,000 (Michigan’s floor is $10,000). Duplexes are an eligible property type, and the longer-runway structure asks for a 640 minimum credit profile on 2-4 unit properties.
Does a Duplex You Live In Get Primary-Residence Treatment?
Yes. If you occupy one unit, the building is generally treated as a primary residence, and that matters more than any other single variable. Occupancy sets the leverage ceiling.
| Occupancy | Max CLTV | Credit pairing | Max line |
|---|---|---|---|
| Primary residence (you live in one unit) | 90% | 720 or better | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 90% | 720 or better | $500,000 |
| Investment property (you rent both units) | 70% | 700 minimum | $500,000 |
The 90% figure exists only at a 720-or-better credit profile. It is not a general ceiling. Lines above $500,000 on a primary residence cap at 75% CLTV and need a full appraisal. They also need a credit profile of 700 or better (720 on the longer-runway program).
An investment-property line works differently. It caps at 70% CLTV and $500,000, and it needs at least a 700 score. Above 700, credit buys eligibility rather than extra leverage.
Occupancy is attested at closing. If you plan to move out soon, the line is priced for what the property is at origination, not what it becomes later. Talk through your timeline with your broker before applying rather than after.
How Underwriting Actually Treats the File
Underwriting tests five things in sequence: income, credit, combined leverage, debt-to-income, and valuation. A bank statement file changes only the first. Title and vesting get their own section below.
Step 1: Income from deposits. Underwriters total eligible deposits over the months reviewed and divide by the number of months. Personal statements generally count at or near face value. Business statements are reduced by an expense factor, because not every dollar deposited is yours to spend. That factor varies by lender and by whether a CPA-prepared profit-and-loss supports a different figure. Transfers between your own accounts, loan proceeds, and one-time deposits are typically stripped out. The statements are read line by line. Business bank accounts need a 680 minimum credit profile for the deposit analysis.
Step 2: Credit. The program floor is 600, using a single-bureau score model keyed to the primary wage earner. The credit report can be no more than 90 days old at closing, and rescores are not available. Tradeline and housing-history standards vary by program. The longer-runway structure wants two tradelines seasoned 12 months or one seasoned 24 months. It also wants a 0x30x6 and 1x30x12 housing history at 640 and above.
Step 3: Combined leverage. The lender adds your first mortgage balance and the new line, then divides by the property value. That is CLTV. Your existing loan keeps its terms, but it still counts in the test.
Step 4: Debt-to-income. Maximum DTI is 50%. It is 45% for profiles from 600 to 679, and a ratio above 45% requires a 680 minimum. The line is qualified on the interest-only payment calculated on the maximum draw, so both your first mortgage and the new line sit in the ratio.
Step 5: Valuation. Lines at or below $500,000 ordinarily use automated valuation, with no traditional appraisal. A higher CLTV may require a secondary valuation. Every line above $500,000 needs a full appraisal, and you can request one at any size.
How the Income Math Looks in Practice
Consider a self-employed designer who lives in one unit of a duplex. Her tax return shows modest net income because of deductions. Her business account shows steady deposits over twelve months.
The lender pulls twelve months of statements and removes transfers and a one-time loan deposit. It applies an expense factor to the business deposits. The result, divided by twelve, becomes her qualifying monthly income. Her first mortgage and the new line’s interest-only payment go into the debt-to-income ratio.
Here is where it can go wrong. If the expense factor takes a large bite and the first mortgage is already sizable, the ratio can exceed 45%. At that point a 680 credit profile becomes the working floor. A borrower at 650 might be fine at a smaller draw and not at a larger one.
No single industry-wide expense factor exists, and Lendmire does not treat one as standard. Ask for the figure in writing for the specific program before you build a plan around the number.
Does Rent From the Other Unit Count?
Usually not as a fix for thin income. This is where borrowers most often misjudge the product. A HELOC is underwritten on borrower income, not property cash flow. That is the core difference from a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Some agency-style approaches count a share of the other unit’s rent, and investors on BiggerPockets mention figures in the 70-75% range. That is anecdotal and does not describe how these programs treat rent. Deposits from your tenant also land in your statements, but a lender reading them may treat rent as a separate stream. Plan as if your own business income has to carry the file.
If the second unit’s rent is the strongest part of your financial picture, the product to look at is a DSCR loan, not a HELOC. That usually means refinancing the first mortgage, which is the trade-off covered below.
Title and Vesting: The Sharp Edge
Title must be held by you as an individual or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. For investors who normally hold property in an entity, this is the biggest structural difference from a DSCR loan.
A property already deeded to an LLC needs either a vesting change or a different product. Moving title can have its own consequences with your existing first mortgage and insurance. Check those before you sign anything. For an entity-held duplex, a DSCR cash-out refinance is the usual fallback, subject to program terms.
Draw Structure and Payment Risk
Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw with a 17-year fully amortizing repayment. The other has a 5-year interest-only draw with a 25-year repayment. Tennessee shortens both, to 3 years and 12 years, and to 5 years and 10 years. At least 75% of the line is drawn at closing. Pricing floats through draw and repayment and never converts to fixed.
That floating feature is the principal risk. The CFPB’s consumer booklet notes that some plans allow interest-only payments during the draw, and that the payment can jump when repayment begins. Stress-test that moment. Ask what your income and your rent need to look like when the interest-only period ends and the balance starts amortizing.
The minimum subsequent draw after closing is $1,000, or $4,000 in Texas. A borrower is limited to three lines. Combined exposure tops out 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.
Where the General Rule Breaks
You move out. The line was priced as a primary residence. If you convert to a rental later, review the loan terms and your lender’s occupancy requirements before you do. Do not assume the pricing tier carries over.
You rent both units. Then the property is an investment property, and the ceiling drops to 70% CLTV with a 700 minimum.
You hold the duplex in an LLC. The line is off the table until title changes.
Texas. A Texas primary residence is a homestead and caps at 80% combined loan-to-value. The matrix tiers above that figure never apply to it. A 12-day waiting period, a one-lien-at-a-time rule, and 12-month seasoning also bind Texas primary residences. Second homes and investment properties follow the standard tables as non-homestead transactions. Properties are limited to 10 acres.
New Mexico and Ohio. The CLTV cap depends on the credit profile in both states.
A listing. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
A recent credit event. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure history splits by program on primary residences. One program seasons a foreclosure at seven years and a deed-in-lieu or short sale at four. The other declines the history entirely.
Unsupported property types. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered. Sub-640 profiles are limited to single-family residences, so a duplex needs at least 640.
Bank Statement HELOC, Cash-Out, or DSCR?
The right choice turns on whether you want to keep your first mortgage and whose income carries the file.
| Factor | Bank statement HELOC | DSCR cash-out refinance |
|---|---|---|
| Reviewed on | Your deposits | Rental income vs. the payment |
| First mortgage | Stays in place | Replaced |
| Title | Individual or revocable trust | LLC may be allowed |
| Occupancy | Primary tier if you live there | Non-owner-occupied only |
| Structure | Floating, draw period | Fixed spine; select options |
A DSCR loan is built for non-owner-occupied investment properties, and because it is a business-purpose investor loan, it is reviewed differently from a standard owner-occupied mortgage. That means it is not a fit while you live in the duplex. Lendmire’s complete DSCR loans guide explains the fork in detail.
The practical split is this. If you have a low-balance first mortgage you want to protect and your deposits support the income, the HELOC route keeps it intact. If you plan to move out and rent both units, a DSCR refinance becomes the cleaner path.
Leverage compounds, too. As one BiggerPockets thread cautions, financing the entire down payment on your next property means you are fully leveraged. That works while rents hold. It stops working when a vacancy lands.
Who Should Skip This
- Borrowers whose duplex sits in an LLC and who cannot move title.
- Anyone relying on the other unit’s rent to rescue a weak income profile.
- Borrowers who need a fixed payment. The line floats and never converts.
- Anyone planning to move out within the first year.
- Owners with a recent foreclosure or a credit profile under 600.
What to Prepare
- Twelve months of personal or business statements, depending on the program.
- A CPA-prepared profit-and-loss, if you want a different expense factor tested.
- Proof of ownership and the current first mortgage statement.
- Insurance and title documents, plus leases for the rented unit.
- A clear timeline for staying in the property.
A broker that shops multiple wholesale lenders can match your deposits, leverage need, and occupancy to the program that fits. That is the real answer to the best-program question. It is a match, not a name.

Frequently Asked Questions
Can I get a bank statement HELOC on a duplex I live in?
Yes, on a 2-4 unit property, subject to lender guidelines. On the longer-runway structure a duplex needs at least a 640 credit profile. You keep your first mortgage, and the property is priced as a primary residence while you occupy it.
What is the maximum CLTV on an owner-occupied duplex?
On a primary residence the ceiling reaches 90% CLTV, but only at a 720-or-better credit profile. Lines above $500,000 cap at 75% CLTV and need a full appraisal. A Texas primary residence caps at 80%.
Does the rent from my second unit help me qualify?
Generally not. A HELOC is underwritten on your income, not on the property’s cash flow. If the rent is your strongest feature, a DSCR loan may fit better once you no longer occupy the building.
Can an LLC own the duplex?
No. Title must be held by you personally or by a revocable living trust. An LLC-held property needs a vesting change or a DSCR cash-out instead, depending on program guidelines.
Do I need a traditional appraisal?
Not usually at or below $500,000, where automated valuation is the norm.
