The Quick Read: A DSCR HELOC is a revolving line secured by one rental, qualified primarily on property-level rental income covering a stress payment, with no personal income calculation, subject to lender guidelines, so a landlord with three doors gets three separate tests, one per property.
- The line sits as a standalone second lien behind the mortgage you keep, or as a standalone first lien on a rental with no mortgage.
- Rent qualifies the line at a minimum 1.10x coverage, tested on the entire credit limit, not just the amount drawn.
- Equity does not pool.
- The weakest door sets the plan, whether the problem is thin rent, thin equity or an ineligible property type.
- Figures here are typical ceilings and floors through select programs, subject to underwriting. They are not offers.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a home equity line of credit on a non-owner-occupied rental, qualified on the rental’s income instead of yours. DSCR stands for debt service coverage ratio. It compares the property’s monthly rent to the monthly payment the lender tests. HELOC means home equity line of credit: you borrow against equity, repay, and can borrow again within the program’s rules.
The label is shorthand. It is not a regulatory term, and it does not describe a single standard product. A traditional HELOC on a rental is underwritten on you: your credit, your debts and your income. The DSCR version is underwritten on the property.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Across the wholesale network Lendmire works with, the structure comes down to two forms:
- Second lien. A new line behind the first mortgage you keep. This is the usual form for a landlord with a mortgage in place.
- First lien. A standalone line on a rental with no mortgage at all.
It is never closed together with a purchase. It is never a third lien. It is never a line on your own home or a second home.

How Does Underwriting Treat the Rent, Step by Step?
The lender qualifies the line by testing whether one door’s rent covers a stress payment on the full credit limit. Your personal income is never calculated. Credit, title, valuation and the lease still get reviewed. Here is the sequence:
1. Pick the collateral door. One property secures the line. Its value and its first mortgage balance set the equity available.
2. Establish 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. A lease in place is required.
3. Build the qualifying payment. The lender assumes a fully amortizing payment on the entire credit limit. It uses the line’s starting rate plus 2 percentage points. This is a stress payment. Taxes and insurance are not part of it.
4. Divide. Gross monthly rent divided by that payment must reach at least 1.10x.
5. Check leverage. On a second lien, the first mortgage balance plus the new line, divided by value, is the combined loan-to-value (CLTV). It tops out at 70%, at a 720 credit score or better.
6. Order the valuation and title work. More on that below. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The stress test runs on the whole line. If you ask for a large limit and plan to draw it in stages, the lender still tests the full limit.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The lender’s own calculation governs. Everything here is illustrative.
Three Doors, Three Setups
“Three doors” can mean different things, and each changes the collateral. The main case here is three separate rentals. Two other versions appear often enough to cover.
| Setup | Collateral | What changes |
|---|---|---|
| Three separate rentals | Three properties, up to three lines | Each door’s own rent, value and first mortgage |
| One three-unit building | One property, one line | Combined unit rents, one valuation |
| Mixed title | Three properties | LLC members sign as guarantors |
A three-unit building is one collateral property. The appraiser reports its rents on a small-income-property form (Form 1025). A two-to-four-unit property may have at most 1 vacant unit.
Vesting in your LLC is allowed on an investment property, subject to lender program eligibility. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment. The borrowers on the line need not be the borrowers on the first mortgage.
A Worked Example, Ratios Only
Run the numbers on three rentals with a different story each. These coverage ratios and leverage percentages are illustrative assumptions, not market data.
Door 1 is a well-rented single-family home. Rent used for lender review covers the stress payment at roughly 1.30x, and the first mortgage plus the new line lands near 60% CLTV. It clears both tests with room to spare.
Door 2 has a lease right at market and coverage near 1.12x. It clears the 1.10x floor, but barely. A smaller limit would improve the ratio, because the stress payment is built on the full limit.
Door 3 has the most equity of the three and the weakest rent, at roughly 0.95x. The equity looks attractive, but the coverage test fails. Cutting the limit might bring it up. A lease above market rent might help, but only with three months of receipts behind it.
The lesson is simple. The door with the most equity is not always the door that qualifies. Rent decides first, and equity second.
One Line or Three?
You need three lines. Equity in Door 1 cannot support borrowing against Door 3, because each line is secured by its own property. One strong door does not rescue a weak one.
Sequencing matters. Start with the door that clears most cleanly. A program permits at most 5 loans or $2,500,000 per borrower, and that count includes loans already placed with the program. Three lines use three of those slots.
The borrowers on each line are tested individually. Credit is the lender’s own report, and the tier it falls in drives leverage. The same guarantor will typically sign for all three, so your personal credit is the common thread across the file.
If you only need cash from one door, run the ratio on all three anyway. It shows which property to use first and which to leave alone.
What Does the Line Look Like After Closing?
The line pays interest only on the drawn balance for 5 years. Then a 25-year fully amortizing repayment period begins. The maturity is 30 years. The rate is variable.
Draws work differently from a credit card. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, which start at $50,000, that means the whole line is drawn at closing. Later draws must be at least $5,000 each. So this is not a card you leave mostly unused.
Here is how the leverage tiers and line sizes stack up, all subject to underwriting:
- Second lien: up to 70% CLTV at a 720 score or better, on lines of $50,000 to $500,000 on a non-owner-occupied rental.
- First lien, lines up to $500,000: up to 75% LTV at 740 or better, or 70% LTV from 700 to 739.
- First lien, lines above $500,000 and up to $1,000,000: 65% LTV at 720 or better. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
There are no reserve requirements and no cash to close. Mortgage history matters: no 30-day late in the last 12 months. The program wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
For valuation, lines to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted. The appraiser’s rent schedule (Form 1007 on single-family homes and condos) sets market rent.
Two six-month clocks apply to seasoning: 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).
Where the General Rule Breaks
Most surprises come from edge cases. These are the ones that come up on three-door files.
- A vacant door. The lease requirement means a vacant single-unit rental has no lease in place, so it does not fit. In a multiunit building, one vacant unit is the limit.
- A lease below market. The lesser-of rule means the lower lease sets the ratio. A lease above market earns credit only with three months of receipts behind it.
- Short-term rentals. The rent schedule form is built around monthly rent, so nightly-rate properties are a poor fit. Short-term rental rules can vary by city, county, HOA and property type, so confirm local rules before relying on projected rental income.
- Ineligible property types. The line does not cover rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use, a property listed for sale in the prior 2 months, or a property with a solar lien. Single-family, townhome, PUD, two-to-four-unit and condominium properties are eligible. A declining-market flag can lower the leverage ceiling by 5 points.
- Borrower status. U.S. citizens, permanent residents and non-permanent residents with a Social Security number qualify. Foreign nationals and ITIN borrowers do not.
- Bank HELOCs on rentals. NerdWallet notes that not every lender offers a HELOC on an investment property, and standards tend to be strict. A bank line underwritten on personal income is a different path than a line qualified on rent.
On the upside, a line does not require you to change your existing first mortgage. That is the core reason many landlords prefer a second lien to a cash-out refinance, which replaces the first mortgage with a new loan. If a low first mortgage is working for you, leave it alone.
What Are the Risks, and When Is It the Wrong Tool?
The main risk is payment change. The rate is variable, so the payment can move while the line is open. A ratio that clears at closing can shift later.
The second risk is the step-up. The CFPB notes that payments on home equity lines are often significantly higher once repayment begins. On this program, the interest-only phase ends after 5 years. Model the repayment-phase payment before you draw heavily.
Coverage also is not profit. The DSCR test compares rent to the qualifying payment only. Repairs, vacancy and management sit outside it.
Concentration is the third risk. Three lines on three doors tie your portfolio together through one guarantor. If two doors soften at once, your cushion shrinks across the board.
The line is the wrong tool in a few cases:
- You want a fixed payment for the long haul. A variable line cannot offer that.
- The rental has no equity beyond what the first mortgage already uses.
- The property falls in an excluded type.
- You want to restructure the first mortgage itself, which calls for a refinance.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment. This program’s minimum is 1.10x.
Second lien: A loan that sits behind the first mortgage. If the property is sold or foreclosed, the first mortgage is paid first.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
Stress payment: A test payment on the full credit limit at a higher assumed rate. It is a qualifying tool, not what you actually pay.
Form 1007: The appraiser’s rent schedule that sets market rent on single-family homes and condos.
Frequently Asked Questions
Can I get a line on each of my three rentals?
Yes, if each one is reviewed on its own. Every door gets its own coverage test, valuation, title review and line, and the program caps exposure at 5 loans or $2,500,000 per borrower. Equity from one property cannot be lent against another.
Can I use a triplex?
Yes. A three-unit building is eligible as one property with one line. The appraiser reports the combined rents on Form 1025. At most 1 unit may be vacant, and the property must carry a lease in place.
What if one door is vacant?
A vacant single-unit rental generally does not fit, because a lease in place is required. In a multiunit building, one vacant unit is allowed. Either way, qualification is subject to underwriting.
Do I need an LLC?
No. Title can sit in your name or in an LLC, subject to lender program eligibility. If an LLC holds title, the members sign as guarantors.
How long must I own the rental before a line is possible?
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).
