The Quick Read: Few large retail banks write a home equity line on a rented duplex, and fewer still qualify it on the rent instead of your paycheck. The lenders that do are mostly specialty wholesale lenders, and a broker is the usual way to reach them. A fully leased duplex is also the cleanest file for them to review.
- A DSCR HELOC (a revolving line of credit that is reviewed on a rental’s income) sits as a standalone second lien behind your first mortgage, or as a first lien on a duplex with no mortgage.
- Through select programs, a second lien reaches 70% combined loan-to-value at a 720 credit score or better, with lines from $50,000 to $500,000, subject to underwriting.
- The rent has to cover a stress payment on the entire credit limit at 1.10x or better, not just on the balance you draw.
- The LLC can stay on title, subject to lender program eligibility.
- Programs change and every file is underwritten individually. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Why Do Banks Rarely Write This Line?
Most large retail banks built their home equity lines for owner-occupied homes. A BiggerPockets discussion among investors and a lender describes the same pattern: availability varies a lot, and the product name matters when you ask.
The label “DSCR HELOC” also means different things depending on who says it. Three products get mixed together:
1. A rent-qualified line. The duplex’s rent decides whether the line works. Your tax returns and pay stubs are not the test.
2. A personal-income HELOC on a rental. This is an ordinary bank line that happens to be secured by an investment property. It still reviews your income, credit and debt-to-income ratio.
3. A DSCR cash-out refinance. This replaces your first mortgage with one new loan. It is not a line of credit.
Here is how the lender types can sort out, though practice differs from one institution to the next. Some banks may steer investment property toward refinancing instead of a line. Community banks and credit unions sometimes write a line, but they usually underwrite your personal income and may limit how many properties you own. A bank’s commercial or portfolio desk may lend when its residential desk will not, so ask for a line of credit secured by investment property. Specialty wholesale lenders write the rent-qualified version. Borrowers usually reach them through a broker.
Lendmire is a mortgage broker that works with a network of wholesale DSCR HELOC lenders. It places the file with the program that fits the property. It does not lend, and it names no lender here. Which program fits depends on your property type, credit, leverage need and how the duplex is titled.
What Is a DSCR HELOC on a Duplex?
A DSCR HELOC on a duplex is a revolving line secured by a non-owner-occupied rental, qualified primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR stands for debt-service coverage ratio: the rent divided by the payment the lender tests.
The structure comes in two forms:
- Standalone second lien. You keep your existing first mortgage, and the line sits behind it.
- Standalone first lien. The duplex has no mortgage, and the line is the only loan on it.
Both are standalone. The line is never closed together with a purchase, never sits in third position, and is never placed on your own home or a second home. If you want the broader picture of how rent-qualified loans work, Lendmire’s complete DSCR loans guide covers it.
The program does not calculate your personal income. There is no traditional personal-income documentation: no W-2s, pay stubs or debt-to-income ratio. The rent, the lease, your credit report and the valuation are all documented and reviewed. The rent replaces the personal income calculation and nothing more.
The duplex can be vested in your LLC, subject to lender program eligibility. The LLC’s members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line also do not have to be the borrowers on the first mortgage.
How Underwriting Treats a Fully Leased Duplex, Step by Step
A fully leased duplex has two rent streams, a lease for each unit, and no vacancy to explain. That is the strongest version of this file. Here is how the review runs on programs of this type.
Step 1: Eligibility. The property has to be a non-owner-occupied rental. A two-to-four-unit property may have at most one vacant unit, and a lease must be in place. A duplex with both units leased answers both questions at once.
Step 2: Rent used for lender review. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. If you have raised rents recently, keep the deposit records.
Step 3: The stress payment. The lender tests a fully amortizing principal-and-interest payment on the entire credit limit. It uses the start rate plus 2 percentage points. Taxes and insurance are not part of this qualifying payment. The test runs on the full limit even though you draw gradually, so size the line with that in mind.
Step 4: The coverage floor. Gross monthly rent divided by that stress payment has to reach 1.10x. Rent that only just covers the payment will not clear it.
Step 5: Leverage. The lender checks equity against the combined loan-to-value ceiling (covered below).
Step 6: Valuation. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, plus a property inspection report. A full interior appraisal is the other route. Lines above $400,000 take a full interior appraisal. Waivers are not accepted. A duplex appraisal uses the two-to-four-unit form, Form 1025. That reference is used here for the form name only. This program sets its own valuation rules.
Step 7: Credit and exposure. A second lien needs a 720 score. A first lien needs 700. The mortgage history must show no 30-day late in the last 12 months. Bankruptcy, foreclosure, short sale or deed-in-lieu must be 48 months back. No reserves or cash to close are required. A borrower can hold at most 5 loans or $2,500,000 with the program.
On a second lien, the lender’s coverage calculation governs how the first-mortgage payment is treated. Confirm on the file how the lender handles it before you count on a number.
A Worked Coverage Example
Run the numbers this way: assume a duplex where both leases match the appraiser’s market rent, so rent used for lender review is the same under every rule. Assume the stress payment on your full requested line lands so that the rent covers it about 1.2x. That clears the 1.10x floor with some cushion.
Now picture the same duplex with a line sized at the top of its range. The stress payment rises with the limit, and coverage might slide toward 1.05x. That falls short of 1.10x.
Several fixes exist. You can request a smaller line, which lowers the stress payment. You can support a lease that sits above market with three months of receipts, which may lift the rent used for lender review. Or you can look at a different structure, such as a DSCR cash-out refinance, which a lender would review under its own rules. None of these is a promise of qualification. Each is a path a lender would review, subject to guidelines, credit approval and property review.
The leverage side works the same way. Say your first mortgage is 45% of the duplex’s value. A second lien at 70% combined loan-to-value leaves 25 points of value for the new line. If the first mortgage were 60% of value instead, only 10 points would remain under that same 70% ceiling. The more you have paid down, the more room a second lien has.
Second Lien or First Lien? The Leverage Tiers
Leverage depends on whether a first mortgage stays in place. The figures below are ceilings for a non-owner-occupied rental, through select programs and subject to underwriting. They are not offers.
| Lien position | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien (keep your first mortgage) | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien (no mortgage on the duplex) | 740 or better | 75% LTV | Up to $500,000 |
| First lien (no mortgage on the duplex) | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien (no mortgage on the duplex) | 720 or better | 65% LTV | Above $500,000, up to $1,000,000 |
CLTV is combined loan-to-value: your first mortgage balance plus the new line, divided by the property’s value. A first lien has no other loan on the property, so it uses plain LTV. The first-lien floor is a 700 score, and the tier rises with the score and the line size, as the table shows. A borrower who keeps a first mortgage can only take a second lien, and that lane starts at a 720 score. There is no second-lien tier below 720.
A first lien exists only on a duplex with no mortgage at all. A declining-market flag lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
The usual reason to choose a second lien is to keep a low-cost first mortgage in place. A cash-out refinance would replace that mortgage. The line leaves it alone.
How the Line Draws and Repays
The structure follows the usual home equity line pattern: a draw period, then repayment. The CFPB’s HELOC explainer describes a revolving line with variable pricing and a payment that can jump when repayment starts. This program’s terms are:
- A 5-year interest-only draw period on the drawn balance.
- A 25-year fully amortizing repayment period, for a 30-year maturity.
- A variable rate.
- At least 80% of the line drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line is drawn at closing.
- Later draws of at least $5,000 each.
The interest-only draw is the stretch where the duplex looks most comfortable, because payments are lowest. The repayment period is where they step up. This is why the stress test runs on a fully amortizing payment. Check your own coverage against that higher payment, not against the draw-period payment.
The rate and the pricing terms come with the lender’s disclosures. Read them before you commit.
Where the General Rule Breaks
Most of the rules above hold on a standard leased duplex. These edge cases change the answer.
A duplex you live in. If you occupy one unit, the duplex is not a non-owner-occupied rental, and this line is never offered on an owner-occupied home. That is a different product with different documentation.
Recently bought or refinanced duplexes. A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date). A duplex you just closed on has to wait.
LLC title. Title in an LLC can complicate a conventional bank line. A BiggerPockets thread on a free-and-clear duplex shows the problem from the borrower’s side. Rent-qualified programs are built for it, with the guarantor structure described earlier.
A recent rehab. An automated valuation may not capture value you just added. If you renovated recently, a full interior appraisal is the safer route, and it may support a higher appraised value depending on comps and underwriter review.
Property types the program excludes. Rural-designated property, row homes, condotels, mixed-use, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, modular and log homes, and land contracts are all outside it. A property listed for sale in the prior 2 months is out.
Borrower status. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Equity does not pool. Each line is secured by one property. Equity in another rental does not back this duplex’s line.
Bank HELOC, DSCR HELOC or DSCR Cash-Out Refinance?
These three get compared often. The table describes each product’s general structure, not any one lender’s terms.
| Factor | Bank HELOC on a rental | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|---|
| What it is | Revolving line | Revolving line | One new closed-end loan |
| Reviewed on | Your income, credit, DTI | Rent coverage | Rent coverage |
| First mortgage | Stays in place | Stays in place (second lien) | Replaced |
| LLC title | Often a hurdle | Allowed on this program | Varies by program |
| Availability | Scarce at big banks | Specialty lenders via a broker | Widely available |
If your first mortgage is one you want to keep, the line is the cleaner tool. If your duplex has little equity or you would like to start fresh on one loan, the refinance may fit better. Either path is reviewed subject to lender guidelines.
Key Terms Defined
DSCR (debt-service coverage ratio): the rent divided by the payment the lender tests. Above 1.00x means the rent exceeds that payment.
Stress payment: a fully amortizing payment on the whole credit limit at the start rate plus 2 percentage points. The lender uses it to test coverage, and you do not pay it as such.
CLTV (combined loan-to-value): all the liens on the property added together, divided by its value.
Lien position: whether your loan is paid first (first lien) or after another mortgage (second lien) if the property is sold or foreclosed on.
Draw period: the stretch when you can borrow from the line and pay interest only on what you have drawn.
Non-owner-occupied: a property you rent out rather than live in.
What to Prepare Before You Ask
A leased duplex gathers its paperwork easily. Have these ready:
- Both unit leases, signed and current.
- Three months of rent receipts, which matter if a lease sits above market rent.
- The LLC documents and guarantor details, if the duplex is in an entity.
- A current first-mortgage statement, if you are taking a second lien.
- The insurance declaration. Hazard insurance covers both liens, and flood coverage applies where required.
- Your credit information and your mortgage payment history.
The decision itself usually comes down to three questions. First, do you want to keep your first mortgage? Second, does the rent cover a stress payment on the full line at 1.10x? Third, does the equity left after the first lien support the line you want? If the answers are yes, the duplex is a natural fit for this program.

Frequently Asked Questions
Do big banks offer a HELOC on a rented duplex?
Some do not, and many steer investors toward a cash-out refinance. Community banks, credit unions and bank commercial desks occasionally write one, and they usually underwrite your personal income. Rent-qualified lines come mainly from specialty wholesale lenders reached through a broker. Availability varies by lender and changes over time.
Can my LLC hold title on a DSCR HELOC?
Yes, on this program, subject to lender program eligibility. The duplex must be an investment property. The LLC’s members sign as guarantors.
How long do I have to own the duplex before I can open the line?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). Both have to be satisfied. A duplex you closed on recently has to season first.
What if one of the two units is vacant?
A duplex with one vacancy is not automatically out. Coverage will be tighter because the vacant unit adds no rent to the test. A fully leased duplex avoids the question and generally gives the lender the clearest picture.
Is a DSCR HELOC better than a DSCR cash-out refinance on a leased duplex?
It depends on your situation. A line keeps your existing first mortgage and gives you a revolving structure with a 5-year interest-only draw period. A cash-out refinance replaces the first mortgage with a single new loan. The right choice turns on your first mortgage, your equity, your credit tier and how you plan to use the funds. Both are reviewed subject to lender guidelines.
