The Quick Read: The best DSCR HELOC program for your situation is a standalone second lien that sits behind your existing first mortgage and is reviewed on the rental’s income. It leaves your first loan’s rate, term and payment untouched. Qualification runs primarily on property-level rent covering the payment, subject to lender guidelines.
- A second lien behind your first mortgage typically allows combined leverage up to 70% CLTV, at a 720 credit score or better, on lines up to $500,000, subject to underwriting.
- The coverage test is a minimum 1.10x, run on a stress payment over the entire credit limit.
- The line is variable-rate, with a 5-year interest-only draw period and a 25-year repayment period.
- Rent qualifies the file. Your tax returns, W-2s and personal income are not calculated, and an LLC can stay on title, subject to lender program eligibility.
- Fit matters more than price. Property type, credit score, equity left after the first mortgage and the first loan’s own note terms decide the outcome.
Lendmire is a mortgage broker, not a lender. It places these lines through a wholesale lender in its network, and every file is underwritten individually.
What Does “Protecting a Fixed First Lien” Actually Mean?
You protect a first lien by leaving it alone. The balance, the rate, the term and the payment all stay exactly as written. A cash-out refinance replaces that loan. A second lien adds a new loan behind it.
Protection covers more than the rate. It also covers:
- Amortization progress. Years of principal paydown stay on the books.
- Remaining term. You are not restarting a 30-year clock.
- No re-underwriting of the first. The original loan is not reopened.
- No new closing costs on the whole balance. The new loan is sized only to the line.
That is why the question comes up. Investors with a low fixed first mortgage on a rental often ask about cash-out refinancing, and the usual answer from other investors is to take a second loan so the first stays in first position, as a BiggerPockets discussion shows.
How Does a DSCR HELOC Sit Behind Your First Mortgage?
It is a standalone second lien. It records behind your first mortgage, and the two payments run side by side. Your first payment continues unchanged. The line payment is added on top.
This program 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. It applies only to a non-owner-occupied one-to-four-unit rental.
Title must show your first mortgage in first position and no other liens. The borrowers on the line do not need to be the borrowers on the first mortgage. If an LLC holds title, the members sign as guarantors. A title holder who is not a borrower signs an acknowledgment and the security instrument.
The structure has one more piece. A HELOC is open-end credit, meaning a line you can borrow against and repay repeatedly. With an existing mortgage, it is a second mortgage paid in addition to the first, and the CFPB’s HELOC explainer describes this same draw-then-repay structure.
How Do You Judge the “Best” Program?
“Best” is mostly a fit question here, not a price question. Across a wholesale network, the right program depends on these six checks:
1. Does the program write a second lien at all? Many do not.
2. Does it qualify on rent or on your personal income?
3. Does it allow LLC vesting?
4. How much CLTV room does your first mortgage leave?
5. Does your first mortgage’s note allow a junior lien?
6. Can you carry a variable-rate line?
Lendmire does not rank lenders or name them. It works with a network of wholesale DSCR HELOC lenders and matches the scenario to the program. The best program for your situation turns on property type, credit profile, leverage need and documentation.
The market is narrow. NerdWallet notes that lenders see higher default risk on investment properties, so fewer lenders offer these lines and borrowing capacity is smaller than on a primary home.
How Does Qualification Work on Rent?
The rent qualifies the line. DSCR, short for debt service coverage ratio, is gross monthly rent divided by the qualifying payment. This program requires a minimum of 1.10x.
The qualifying payment is not your actual payment. It is a fully amortizing payment on the entire credit limit, at the start rate plus 2 percentage points. That is a stress payment. It applies to the whole line, even if you draw only part of it.
Here is how the pieces work:
- Rent counts at the lesser of two numbers. One is the appraiser’s market rent on Form 1007. The other is the lease. A lease above market counts only with three months of receipts.
- A lease in place is required. A two-to-four-unit property may have at most 1 vacant unit.
- The first mortgage payment is a question for the lender. Whether it joins the qualifying payment on a second lien is the lender’s own calculation. Confirm it before you assume a number.
No traditional personal-income documentation, W-2s, pay stubs or debt-to-income ratio enter the file, subject to lender guidelines. The rent, lease, credit report and valuation are all documented. Think of it as qualifying on the rental’s income, not on your paycheck.
Here is an illustration. A rental with rent that comfortably clears the stress payment on the full limit passes. The same rental with a limit sized too large can fall below 1.10x. Sizing the line smaller is often the fix. The lender’s calculation governs.

How Much Can You Borrow Behind the First?
Leverage is combined. CLTV is your first mortgage balance plus the new line, divided by the property’s value. On a second lien behind your first mortgage, this program typically reaches 70% CLTV at a 720 credit score or better, on lines from $50,000 up to $500,000, subject to underwriting.
The room left is simple arithmetic. Take 70% of value, then subtract what you owe on the first. What remains is the most the line could be. A rental you just bought or refinanced often leaves little room.
If your first mortgage already uses most of the 70%, the room may fall below the $50,000 minimum line. Then there is no offer. That is a common dead end for newer purchases.
A first lien works differently. On a rental with no mortgage, loan-to-value can reach 75% at 740 or better, on lines up to $500,000. It is 70% from 700 to 739. Lines above $500,000, up to $1,000,000, carry a 65% ceiling. Those are first-lien LTV figures, not second-lien CLTV. A declining-market flag lowers the ceiling 5 points, and Philadelphia lines carry a ceiling 10 points lower.
| Factor | Second lien (keeps your first) | First lien (no mortgage) |
|---|---|---|
| Leverage | Up to 70% CLTV | Up to 75% LTV |
| Credit floor | 720 | 700 |
| Line size | $50,000 to $500,000 | $50,000 to $1,000,000 |
| Over $500,000 | Not available | 65% LTV |
How Do Draws, Terms and the Variable Rate Work?
The draw period is 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable, so your payment can move.
This is not a credit card you swipe as needed. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each. Plan your cash need before you size the line.
The CFPB notes that payments are based on the current balance and that some plans require an initial draw. That matches how this program works.
A variable-rate second on top of a fixed first is the real tradeoff. Your first payment is predictable. The line payment can change. If payment certainty matters to you, size the line modestly and draw only what a specific project needs.
What Does the File Require?
The file is lighter than a personal-income file, but not empty. Expect:
- Current leases and a rental appraisal form showing market rent.
- A property valuation. Lines 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. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
- Title work. A full title policy applies on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report.
- Entity documents if an LLC holds title.
- Hazard insurance covering both liens, and flood coverage where required.
Credit has a few specific points. No 30-day mortgage late in the last 12 months applies. A bankruptcy, foreclosure, short sale or deed-in-lieu needs 48 months behind it. No reserves and no cash to close are required. Each borrower is limited to 5 loans or $2,500,000 with the program.
Seasoning is the waiting period between events. 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).
US citizens, permanent residents and non-permanent residents with a Social Security number may qualify. Foreign nationals and ITIN borrowers are not eligible on this program.
Where Does the Rule Break?
Most of these dead ends are property or structure issues, not credit issues.
- Property type. Single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots to 10 acres are eligible. 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 not.
- Recent listing. A property listed for sale in the prior 2 months is out. So is a property with a solar lien.
- Your own home. This line is never offered on an owner-occupied home. A line on your primary residence is a different product and moves the risk to the house you live in.
- First mortgage terms. Read your note and deed of trust for subordinate-financing or due-on-sale language before you apply. The first lender’s servicer will not tell you this on its own.
- Bank refusals. Investors report that conventional banks often decline a rental HELOC where a mortgage already exists. Network programs exist because that gap is real.
- Value drops. The CFPB brochure says a lender may reduce or freeze a line if the home’s value falls significantly, and that a HELOC is generally payable in full on sale. Plan for both.
- Cross-default risk. A second lien adds a new loan secured by the same property. Missing payments on the line can put the property at risk, which touches the first lien too.
When Does a Cash-Out Refinance Win Instead?
A second lien is not always the better answer. The lender-side view in that same BiggerPockets thread is a useful test. A line makes sense when it is small relative to the existing mortgage balance. A cash-out makes more sense when the cash need is large relative to the balance.
Consider your first mortgage honestly:
- Is it worth protecting? If your first loan’s terms are only slightly better than today’s market, a cash-out may cost little in lost advantage.
- Do you need a large sum? A large cash need can exceed the CLTV room behind your first.
- Do you want one payment? A cash-out gives one loan. A second lien gives two.
- Do you want fixed payments only? A variable line may not fit.
A cash-out resets the whole balance and carries closing costs on all of it. A second lien prices only the new money. Neither is better by default.
Who Is This For, and Who Is It Not For?
| Fits | Does not fit |
|---|---|
| Owns a rental with a first mortgage worth keeping | First-time investor with nothing to pledge |
| Wants equity without opening the income file | Owner-occupied home or second home |
| Holds title in an LLC | Property outside the eligible types |
| Credit at 720 or better for a second lien | Little equity left behind the first |
A first-time investor has nothing to pledge. The usual sequence is a purchase loan first and a line later. A line on an existing rental can then fund the down payment on the next one, followed by a separate purchase loan.
How Do You Prepare Before You Apply?
Gather these items before a broker shops your file:
1. Your latest first-mortgage statement and payoff figure.
2. The note and deed of trust, checked for junior-lien language.
3. Current leases and rent receipts.
4. Entity documents, if an LLC holds title.
5. Insurance evidence.
6. Your credit profile, since the tier comes from the lender’s own report.
Then run your CLTV room. Calculate 70% of value, subtract your first balance, and see whether at least $50,000 remains. If it does, the file is worth shopping. A broker who works with multiple wholesale lenders can match the property, rent, equity and credit to the program that fits.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Tax treatment varies; consult a qualified tax professional.

Frequently Asked Questions
Does a DSCR HELOC change my first mortgage?
No. The first mortgage’s balance, rate, term and payment stay as they are. The line records behind it as a separate loan, and both payments are due. Check your first loan’s note for any junior-lien restrictions before applying.
Can an LLC hold title on the line?
Yes, on 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 and the security instrument. This is a common point of failure at bank-style lenders, which often want individual title.
What credit score do I need?
The program typically requires a 720 minimum on a second lien and 700 on a first lien, using the lender’s own credit report. A second lien gets no cell below 720. Mortgage history needs no 30-day late in the last 12 months, subject to underwriting.
Is a DSCR HELOC the same as a bank HELOC on a rental?
No. A bank rental HELOC is underwritten on you personally, with credit, income and debt ratios. NerdWallet reports that lenders surveyed look for a 720 score, six months of reserves and 20% equity. This program qualifies primarily on the rental’s income, with no reserves required, subject to lender guidelines.
What happens if the rent does not clear 1.10x?
The file fails the coverage test as submitted. A smaller line lowers the stress payment and may bring the number into range. The lender’s own coverage calculation governs the final result.
If you are considering a home equity line on a rental property and want to see how the numbers work, Lendmire can help you compare DSCR HELOC options based on the property, the rent, the equity available, credit profile, combined leverage, and your goals.
