The Quick Read: A DSCR HELOC lets you borrow against a rental’s equity as a standalone second lien behind the first mortgage you keep, and the rent qualifies the line instead of your personal income, so the best program for your situation depends on your equity, credit, and property type.
- The first mortgage stays untouched. The new line is recorded behind it.
- Combined loan-to-value (CLTV) on a second lien is up to 70% at a 720 credit score or better, through select programs and subject to underwriting.
- Rent must cover a stress payment on the whole credit limit at 1.10x or better.
- A low first-mortgage balance is what creates the room. A high one can leave none. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Key Terms Defined
DSCR (debt service coverage ratio): The property’s gross monthly rent divided by the payment the lender uses to test the loan.
HELOC: A revolving line of credit secured by property, where you borrow, repay, and borrow again during a set draw period.
Second lien: A loan recorded 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 full new line, divided by the property’s value.
Stress payment: A hypothetical payment on the entire credit limit at a higher test rate, used only to measure rent coverage.
Seasoning: The waiting period a lender wants after you buy or refinance a property before you borrow against it.
Why a Ranked List of Providers Misleads
Nobody can honestly hand you a single ranked list of providers for this loan, because the right answer changes with the file. Equity, credit tier, property type, and whether the first mortgage allows a junior lien all steer you toward different programs. Lendmire is a mortgage broker, not a lender. It works with a network of wholesale lenders and matches the scenario to the program, so this article explains how those programs operate instead of naming companies.
The label also confuses people. “DSCR HELOC” is a market label, not one standardized product. Some lenders use it for a closed-end second loan that pays out as a lump sum. Others use it for a true revolving line. The program described here is the revolving line, available in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Here is how the main routes to a rental’s equity differ.
| Factor | Bank HELOC on personal income | DSCR HELOC | DSCR cash-out refinance |
|---|---|---|---|
| Reviewed on | Your income and debts | Rental income | Rental income |
| First mortgage | Stays, if allowed | Stays | Replaced |
| Structure | Revolving line | Revolving line | Lump sum |
| LLC on title | Often refused | Allowed, subject to program terms | Allowed, subject to program terms |
| Best fit | Strong traditional employment income | Low first, thin tax income | Rate on first is not worth keeping |
The first column describes how a bank investment HELOC qualified on personal income generally works. Terms vary by institution, and many large retail lenders do not write rental-property lines at all.
What a DSCR HELOC Behind a Low First Mortgage Actually Is
It is a standalone second lien on a rental you already own, written next to the first mortgage you keep. Lien position follows recording order. A line recorded behind your existing mortgage can only be a second lien. A first lien exists only on a rental with no mortgage at all.
Three points define the structure:
- Rent qualifies the line. There is no traditional personal-income documentation: no W-2s, pay stubs, or debt-to-income ratio. The file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
- Your LLC can hold title. Vesting in your LLC is allowed on investment property, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
- The borrowers need not match the first mortgage. The people on the line do not have to be the people on the first loan.
It is not a purchase tool. The line is never closed together with a purchase, so you must already own the rental. It is also never a third lien, and never a line on your own home or a second home.
How Underwriting Treats the File, Step by Step
Underwriting here still looks hard at credit, equity, property, valuation, and title. Only the personal-income test is swapped for property-level coverage. The order below is the order a broker walks a file.
Step 1: Confirm the lien position. Read the first-mortgage note and deed of trust for any limits on added liens. Another existing line on the rental would push the new one to third position, and this program does not write third liens. Hazard insurance must cover both liens, with flood coverage where required.
Step 2: Compute CLTV. Add the first-mortgage balance and the full new line, then divide by value. Experian describes this same combined formula, which lenders use to limit home-equity borrowing. The full line counts, not just the amount you draw.
Step 3: Test rent coverage. The test needs gross monthly rent of at least 1.10x the qualifying payment. That payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It covers principal and interest only, never taxes and insurance. 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. A two-to-four-unit property may have at most 1 vacant unit.
Whether the first-mortgage payment joins the qualifying payment on a second lien is not published, so the lender’s coverage calculation governs. Confirm on the file how the lender treats the first-mortgage payment.
Step 4: Check credit. A second lien needs a 720 score or better, and the tier is the lender’s own report. Mortgage history must show no 30-day late in the last 12 months. The file also needs 48 months since any bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves and no cash to close are required, through select programs.
Step 5: Value the property. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better plus a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
Step 6: Clear title. A full title policy is required on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report.
Step 7: 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).
How Much Room Does a Low First Leave?
The sizing formula is simple: the maximum new line equals the CLTV ceiling times value, minus the first-mortgage balance. The ceiling on a second lien is 70% CLTV, subject to underwriting.
Run it in percentages. Say your first mortgage balance equals 40% of the property’s value. Take the 70% ceiling and subtract 40%, and the new line can reach up to 30% of value. Now say your first balance equals 60% of value. The room shrinks to 10% of value, which on a modest property may fall under the $50,000 minimum line.
This is why a low first mortgage matters so much. The same property, with a first balance near 25% of value, leaves up to 45% of value in room. On a higher-value property, the program’s $500,000 line ceiling could become the limit instead of the equity.
Coverage tightens as the line grows, because the stress payment is calculated on the whole limit. A larger line can clear the CLTV test and still miss 1.10x on rent. Equity and rent both have to work, and the lender’s own arithmetic governs either test.
Draw Rules and the Structure of the Line
The program runs a 5-year interest-only draw period on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
At least 80% of the line is 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 are at least $5,000 each. So this is not a standby line you open and leave idle. It suits an owner who needs a large amount of capital now and wants some flexibility afterward.
The CFPB explains that a HELOC is open-end credit with a draw period followed by a repayment period, and that payments on a variable-rate line can change from month to month. Two risks follow for you:
- Variable-rate drift. Stress your own numbers with higher payments than you expect today.
- End-of-draw payment jump. When the 5 interest-only years end, principal begins to amortize, and the payment steps up.
A DSCR loan is designed for non-owner-occupied investment property. Because it is a business-purpose investor loan, it is reviewed differently from a standard owner-occupied mortgage. The eCFR’s official interpretations of Regulation Z state that a business-purpose loan secured by a dwelling is not subject to that regulation’s consumer rules. Expect the lender’s HELOC disclosures to spell out the rate and pricing terms.
Where the General Rule Breaks
A rental with no mortgage. The same line can be written as a standalone first lien, but only on a rental that carries no mortgage. Leverage then runs by score tier. On lines up to $500,000, a 740 score or better reaches 75% LTV, and 700 to 739 reaches 70% LTV. On lines above $500,000, up to $1,000,000, the ceiling is 65% LTV at 720 or better. The first-lien floor is 700.
A score of 700 to 719 with a first mortgage. An owner who keeps a first mortgage can only take a second lien, and the second-lien floor is 720. A score in this range therefore does not qualify. Below 720 there is no second-lien tier. Raising the score, paying down the first mortgage, or choosing a different product are the usual paths.
Ineligible property types. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, and mixed-use are outside this lane. So is a property listed for sale in the prior 2 months and a property with a solar lien. Single-family, PUD, townhome, two-to-four units, condominiums, and lots up to 10 acres are eligible property types.
Market adjustments. A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
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.
Exposure limits. The program allows at most 5 loans or $2,500,000 per borrower.
A first mortgage that restricts junior liens. Read your own documents first. If the first mortgage restricts added liens, a second lien may not be possible. A later refinance of the first will also have to deal with the new second lien, which can complicate it. Lendmire’s explainer Top HELOC Providers When Subordinating Behind an Existing First Mortgage covers the mechanics of that position.
A primary-residence HELOC as a down-payment source. Many investors use equity in their own home to fund a deposit, but that is a different, owner-occupied product. This rental-based line is never offered on an owner-occupied home. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Keep the First or Replace It?
Keeping a low first mortgage preserves a cheap loan. The tradeoff is that the second lien is a separate, often more expensive, variable-rate loan. A blended cost across the first and second can end up higher than one new cash-out loan, depending on pricing and how long you hold the property. The honest comparison is the blended cost of the two loans against the cost of replacing both with one DSCR cash-out refinance.
Use these situations as a guide:
- Keep the first and add a line when the first mortgage is clearly low-cost, the balance is small against value, and you want to draw capital in stages.
- Refinance instead when the first is only slightly below market, the balance is large, or you want a single lump sum with one payment.
- Pause when the first mortgage restricts junior liens, when you plan to refinance the first soon, or when your score sits below 720.
Lendmire’s DSCR loan guide covers the underlying qualification logic in full. A comparison article on HELOC versus cash-out refinance on a rental can help you run the side-by-side.
How to Vet a Provider
Because the best provider depends on your file, vet each program with direct questions. A broker that shops several wholesale lenders can ask them for you. Ask these:
1. Is this a revolving line or a closed-end second loan?
2. Does the lender write a second lien behind a kept first mortgage on a rental, and at what CLTV ceiling for my score?
3. How does the lender treat the first-mortgage payment in its coverage calculation?
4. Can the property be vested in my LLC, and what does the lender require from the members?
5. What valuation does it require at my line size, and are waivers accepted?
6. What are the minimum draw at closing and the minimum later draws?
7. What happens when the draw period ends?
8. Where are the rate and pricing terms disclosed, and how do I read them?
A lender that cannot answer questions three and seven plainly is not ready to take your file.
What to Bring
Gather the lease or rent schedule, your mortgage statement, your credit authorization, and the entity documents if an LLC holds title. You also need proof of hazard insurance. Rent receipts for three months help if your lease is above market rent. There is no personal income package to assemble.
Frequently Asked Questions
Can I add a DSCR HELOC without touching my existing first mortgage?
Yes. The line is a standalone second lien, so the first mortgage’s note and terms stay as they are. You still need to confirm the first mortgage allows a junior lien, and the combined balance must fit within the 70% CLTV ceiling on a second lien, subject to underwriting.
Do I need a minimum credit score?
On a second lien, the floor is 720, and that tier carries the 70% CLTV ceiling. On a first lien for a rental with no mortgage, the floor is 700. These are select-program figures, and every file is reviewed individually.
Can an LLC borrow?
Yes, subject to program terms. The members sign as guarantors, and any title holder who is not a borrower signs the non-borrowing owner acknowledgment and the security instrument. Many bank HELOCs refuse LLC-titled property, which is one reason investors look to rent-qualified programs.
How long must I own the rental first?
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). A recent purchase or refinance resets the first clock.
Is this available everywhere?
No. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is a broker, not the lender, and programs and eligibility are subject to lender guidelines.
