The Quick Read: A DSCR HELOC is a revolving line of credit recorded behind the first mortgage you keep. It qualifies primarily on the rental’s income covering the payment, rather than your personal income, subject to lender guidelines, so your existing first mortgage stays untouched. The best program for your situation depends on combined leverage, credit score, property type, and how the lender runs the coverage test. No single headline feature decides it.
- On a second lien behind a first mortgage on a non-owner-occupied rental, combined leverage tops out at 70% CLTV at a 720 score or better, with lines from $50,000 to $500,000, through select programs and subject to underwriting.
- The rent must clear a 1.10x minimum against a stress payment calculated on the whole credit limit.
- The line has a 5-year interest-only draw period, a 25-year repayment period, a 30-year maturity, and a variable rate.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
What a Second-Lien DSCR HELOC Actually Is
It is a market label, not a standardized product. Lenders build these lines differently, so the label tells you less than the guidelines do.
The version Lendmire brokers is a standalone second lien on a rental you keep financed. It can also be a standalone first lien on a rental with no mortgage. It is never closed together with a purchase, never a third lien, and never a line on your own home or a second home.
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.
Why would an investor want this? Many owners hold a first mortgage they would never replace on today’s terms. A cash-out refinance swaps that loan for a new one. A second-lien line leaves it in place and adds a separate loan behind it.
Lendmire is a mortgage broker, not a lender. It works with many of the nation’s largest wholesale DSCR HELOC lenders and matches the scenario to the program. Non-QM lending has grown as a share of the market: HousingWire reports Optimal Blue data showing non-QM at 12% of September production. More originators are entering this space, which is why program details vary so much.
Key Terms Defined
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 new line, divided by the property’s value.
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment. Above 1.00x, the rent covers the payment.
Draw period: the stretch when you can borrow from the line and pay interest only on what you drew.
Subordination: a written agreement by the second-lien holder to stay behind a new first mortgage. You need it if you refinance the first loan later.
How Underwriting Treats the File, Step by Step
Underwriting follows the same order on most files across the wholesale network. The first two steps decide whether a file moves forward at all.
1. Collateral. The property must be a non-owner-occupied one-to-four-unit rental. Single-family, PUD, townhome, two-to-four-unit, and condominium properties are eligible, including non-warrantable condos. Lots up to 10 acres also fit.
2. First mortgage review. The lender looks at the first loan’s balance. You should read its note and security instrument for restrictions on additional liens or due-on-sale language. A first mortgage that blocks junior liens ends the second-lien path before it starts.
3. Combined leverage. The lender adds the first balance to the new line and divides by value. At a 720 score or better, the ceiling is 70% CLTV on a second lien. Below 720 there is no second-lien option on this program.
4. Coverage test. Gross monthly rent is divided by a qualifying payment. That payment is a fully amortizing payment on the entire credit limit at the starting rate plus 2 percentage points. The minimum is 1.10x. Whether the first mortgage payment joins that calculation on a second lien is set by the lender’s own coverage method, so ask before you size the line.
5. Rent figure. Rent is the lesser of the appraiser’s Form 1007 market rent or the lease. A lease above market rent counts if you document three months of receipts. A lease in place is required, and a two-to-four-unit building may have at most one vacant unit.
6. Valuation. Lines up to $400,000 use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal (Form 1004, 1073, or 1025). Appraisal waivers are not accepted.
7. Title and insurance. A full title policy is required on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report. Hazard insurance must cover both liens, and flood coverage applies where required.
The personal side is light but not empty. You need a 720 credit score on a second lien, no 30-day mortgage late in the last 12 months, and 48 months since any bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves or cash to close are required. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
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 Do You Judge the Best Program?
The best program depends on the property, the equity, and the borrower. A scorecard works better than a ranking, because the lenders that write this product differ on the points below.
| Criterion | Why it matters | What to ask |
|---|---|---|
| Lien flexibility | Decides if a second is allowed | Is a standalone second offered? |
| Coverage method | Changes how much you can borrow | Does the first payment count? |
| Draw structure | Sets your usable cash | Minimum draw at closing? |
| Entity title | Affects asset protection | Can the LLC stay on title? |
| Property types | Can disqualify a rental | Are condos and 2-4 units eligible? |
| Seasoning | Blocks recent purchases | When does each clock start? |
| Exposure cap | Limits portfolio growth | How many loans per borrower? |
Across the network, the draw rules surprise people most. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws must be at least $5,000 each. So this is not a standby fund. You will carry most of the line from day one.
Second Lien, First Lien, or Cash-Out Refinance?
The structure you pick decides what happens to your first mortgage.
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Product type | Revolving line | New loan |
| Borrowing | Draws after closing | Lump sum |
| Coverage test | Stress payment on full limit | Set by that program |
A bank-style investment HELOC works differently from both. Those lines are typically underwritten on the owner’s personal income and debt-to-income ratio, which is a different rule set from property-rent-based lender review.
A rental with no mortgage can take a standalone first-lien line. Leverage there reaches 75% LTV on lines up to $500,000 at a 740 score or better. It drops to 70% LTV at 720 to 739, and to 70% LTV at 700 to 719, which is the first-lien floor. Lines above $500,000, up to $1,000,000, are capped at 65% LTV at 720 or better. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Each loan is underwritten on its own property, but exposure is capped at five loans or $2,500,000 per borrower with the program.
A Worked Combined-Leverage Example
Run the numbers on a rental with a 740 credit score behind it. The figures below are illustrative, and the lender’s own calculation governs. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Say the first mortgage sits at 40% of the property’s value. The ceiling is 70% CLTV, so the new line can use up to 30% of value.
Now say the first mortgage sits at 60% of value. Only 10% of value is left. That may not support the $50,000 minimum line unless the property is quite valuable.
A declining-market flag lowers the ceiling by 5 points. A larger first mortgage always shrinks the room for a second, which is why a recently refinanced rental often has less usable equity than owners expect.
Coverage works the same way. Suppose the rent clears the stress payment on a modest line at around 1.25x. That passes the 1.10x minimum. Raise the line and the stress payment rises with it, because it is calculated on the entire limit. The rent has not changed, so the ratio slides toward the floor. The line size that works is the one where coverage still clears 1.10x, whatever the equity would otherwise allow.
DSCR files with a keeper first mortgage often come in with plenty of equity and thin coverage. Investors who bought a rental in a lower-rent area often hit the coverage wall before the leverage wall. Checking rent against the Form 1007 market figure early prevents a surprise at valuation.
Where the General Rule Breaks
Most of these edge cases show up in the first week of a file. Check them before you order anything.
- Ineligible property types. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, and land trusts are outside this program. So are age-restricted communities, hobby farms, modular and log homes, land contracts, and mixed-use. A property listed for sale in the prior 2 months and a property with a solar lien are also out.
- Metro overlays. One city, Philadelphia, carries a ceiling 10 points lower than the standard tiers.
- Entity title. LLC vesting is allowed, subject to lender program eligibility. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line do not have to be the borrowers on the first mortgage.
- A later refinance of the first. The second-lien holder must agree to subordinate so the new first mortgage keeps its priority. This is a real source of friction, so ask about it before you take the line.
- Foreclosure position. In a shortfall, the second sits behind the first. That is why second-lien leverage ceilings are tighter than first-lien ceilings.
- Variable payments. The CFPB explains that a home equity line has a draw period followed by a repayment period, and that payments are often significantly higher in repayment. Its HELOC brochure adds that payments can change even if you draw no more, because the rate is variable. This program follows that shape: 5 years of interest-only payments, then 25 years of full amortization.
Who Should Skip It
A second-lien line is the wrong tool in several situations.
- Your first mortgage restricts additional liens, and you cannot get a waiver.
- Your first mortgage is already large relative to value, leaving little room under the 70% CLTV ceiling.
- The rent barely covers the existing obligations, so coverage will not clear 1.10x on a line sized for your goal.
- You want to buy a property. This line is never closed with a purchase, so a separate purchase loan buys the next rental.
- You want the option to draw later in small amounts. With most of the line drawn at closing, that flexibility is limited.
If the numbers do not work for a second lien, a DSCR cash-out refinance may be the better structure.
Use of funds also matters. Tax treatment varies; consult a qualified professional before relying on any deduction.

Questions to Ask Before You Apply
Take these to any lender or broker.
1. Does the first mortgage allow a second lien, and will the lender need a subordination agreement later?
2. How is the coverage payment calculated, and does the first mortgage payment join it?
3. What combined leverage applies at my credit score and property type?
4. Is the commitment or only the drawn balance counted toward CLTV?
5. Which valuation path applies to my line size?
6. Can my LLC stay on title?
7. Do the rate and the pricing terms come with the lender’s disclosures before I commit?
Frequently Asked Questions
Can a DSCR HELOC sit behind any first mortgage?
Usually, but the first mortgage’s own terms come first. A first mortgage that restricts additional liens, or has strict due-on-sale language, can block a second. Review the note and security instrument before you apply, and the lender’s title work will confirm lien position.
Does the line replace my first mortgage?
No. The first mortgage keeps its priority, its terms, and its payment. The line is a separate loan recorded behind it, which is why combined leverage, not the new line alone, is what the lender measures.
Can my LLC hold title?
Yes, on investment property only, subject to lender program eligibility. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
What credit score do I need?
A 720 score or better on a second lien, and 700 or better on a first-lien line, through select programs and subject to underwriting. The tier comes from the lender’s own credit report.
Can I use the line to buy my next rental?
Not directly. The line is never closed together with a purchase. You can draw on it after closing and use the funds toward a purchase loan’s down payment, but the purchase itself needs its own financing.
