The Quick Read: A DSCR HELOC is a revolving line of credit on a rental you own, written as a standalone second lien behind the first mortgage you keep, and qualified on the property’s rent rather than your personal income. Your first mortgage’s balance, term, and payment stay exactly as they are. That makes the line a fit for a temporary capital need, as long as you plan the draw and the exit before you sign.
- The line sits behind your first mortgage, so nothing about that loan changes.
- Qualification runs on rent: a minimum 1.10x coverage on a stress payment over the whole credit limit, subject to lender guidelines.
- Through select programs, a second lien reaches 70% combined loan-to-value at a 720 credit score or better, on lines from $50,000 to $500,000.
- At least 80% of the line is drawn at closing, so interest starts on most of the line immediately.
- It is a variable-rate, interest-only draw structure. Plan how you will pay it down.
What Is a DSCR HELOC?
A DSCR HELOC is a home equity line on a non-owner-occupied one-to-four-unit rental. The property’s rent, not your paycheck, qualifies it. No traditional personal-income documentation, W-2s, pay stubs, or personal debt-to-income calculation are involved, subject to lender guidelines. The credit report, the lease, and the valuation are all still documented.
The line is secured by a rental you keep. It is never closed together with a purchase, never a third lien, and never placed on your own home or a second home. On a rental with no mortgage, the same line is written as a standalone first lien instead.
Lendmire is a mortgage broker. It arranges these lines through a wholesale lender in its network, and the lender reviews and approves each file. Across that network, this is one of the cleaner ways to reach rental equity without touching a low-rate first mortgage. The broader complete DSCR loans guide covers how property-rent-based lender review works across products.
The term “DSCR” describes the qualifying method, not a different legal product. It is a home equity line with a different way of proving you can carry it.
Why Does Keeping the First Mortgage Matter?
Keeping the first mortgage matters because a cash-out refinance replaces it. A second lien does not. The first mortgage keeps its balance, term, and payment, which matters most when that loan is cheaper than anything you could get today.
If the property is sold or foreclosed, the first lender is paid first and the line is paid from what remains. That ordering is why the line is called a second lien. It also means the rental now carries two loans, and missing payments on either can lead to foreclosure.
For a short-term need, the trade is simple. You pay for a second loan only while the balance is drawn, instead of resetting your whole mortgage to fund a need that may last months.
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays in place | Replaced |
| Funds access | Revolving line, after the first draw | One lump sum |
| Payment behavior | Interest-only draw period | Fully amortizing |
| Fit for a short horizon | Often stronger | Often heavier |

How Does Underwriting Treat a DSCR HELOC, Step by Step?
Underwriting follows a set order: collateral, equity room, rent coverage, valuation, seasoning, and then the credit report. Each step can end the file, so it helps to check them in this sequence before applying.
Step 1: The collateral. It must be a rental you own and keep. Eligible types include single-family, PUD, townhome, two-to-four units, and condominiums, plus lots up to 10 acres. Rural-designated property, condotels, row homes, leaseholds, and a property listed for sale in the prior 2 months fall outside this lane.
Step 2: The equity room. Combined loan-to-value is your first mortgage balance plus the new line, divided by the property’s value. On a second lien, the cap is 70% combined at a 720 credit score or better. If your first mortgage already uses most of that room, the space left may be smaller than the $50,000 minimum line, and there is no offer to make.
Step 3: The rent test. The minimum coverage is 1.10x. That is gross monthly rent divided by a qualifying payment, and that payment is a fully amortizing payment on the entire credit limit at a stress rate. The test runs on the whole line, not just what you draw. A $200,000 line is tested as if fully drawn.
Rent is the lesser of the appraiser’s market rent (Form 1007) or your lease. A lease must be in place. On a two-to-four-unit property, at most one unit can be vacant.
One point catches people off guard. Whether your first-mortgage payment joins the qualifying payment on a second lien is not something to assume. The lender’s own coverage calculation governs, so a second lien should not be treated as a copy of a purchase loan.
Step 4: The valuation. Lines up 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.
Step 5: 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).
Step 6: Credit. A second lien needs a 720 minimum. The history requirement is no 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves and no cash to close are required, subject to underwriting.
What Does the Draw Look Like for a Short-Term Need?
The draw is the part that most affects a short-term plan. 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.
That is not how many people picture a line of credit. As the CFPB’s overview of home equity lines notes, some plans require a minimum amount each time you borrow, or an initial amount when the line is set up. On this program, the initial draw is large.
So interest is running on most of the line from the start. A line sized for a flexible, standby cushion is the wrong picture. The right picture is a mostly drawn loan that you intend to pay off.
During the draw, you pay interest only on the drawn balance, for 5 years. After that, a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable, and the rate and pricing terms come with the lender’s disclosures.
A short-term need rarely reaches the repayment period. But the interest-only phase is why the payment stays modest while the balance is drawn, and why a clear payoff plan matters. The CFPB’s HELOC booklet explains that HELOCs typically involve variable rather than fixed interest rates, which means the cost of carrying the balance can move.
Which Structures and Variations Exist?
A few structural choices change how the line behaves. Check which one you are actually being offered.
First lien versus second lien. On a rental with no mortgage, the line is a first lien. Leverage is stated as loan-to-value rather than combined. On an investment property with no mortgage, a first lien reaches 75% at a 740 score or better. It reaches 70% at 700 to 739 on lines up to $500,000. Lines above $500,000, up to $1,000,000, are capped at 65% LTV. The first-lien floor is a 700 credit score, subject to underwriting. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
LLC title. Vesting in the owner’s LLC is allowed on an investment property. 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 need not match the borrowers on the first mortgage. This is subject to program terms.
Revolving versus closed-end. Some products sold as a home equity line are really closed-end seconds that pay out one fixed amount. A real line lets you draw again after the initial draw, in $5,000 pieces or more. If you need a lump sum with a fixed term, a closed-end second may fit better. If you need staged access, confirm the product is truly revolving.
Borrower and portfolio limits. US citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
Footprint. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Property and borrower eligibility still apply inside those states.
Where Does the General Rule Break?
The general rule is that rent qualifies the line and the first mortgage stays untouched. Several edge cases bend that.
The coverage math can squeeze the line size. Because the stress payment is tested on the entire limit, a property with modest rent may support a smaller line than its equity would suggest. Leverage room and rent coverage both have to clear. Whichever is tighter sets the ceiling.
The line does not replace reserves. A lender can reduce an undrawn balance, so an unused portion is a weak substitute for cash on hand. Do not count on undrawn room as an emergency fund.
A declining market lowers the ceiling. A declining-market flag lowers the cap by 5 points. Philadelphia lines carry a ceiling 10 points lower. A solar lien takes the property out of eligibility.
Insurance covers both liens. Hazard insurance must cover both loans, with flood coverage where required.
Using it to buy. A line only supplies cash. The purchase lender must accept borrowed funds, and on most files a new property’s coverage ratio is read against that property’s own payment. Confirm this with whoever is writing the purchase loan before you draw.
Cash flow on the borrowed property. The line adds a payment to the property that secures it. A higher payment can turn a cash-flowing rental into a break-even one. Stress-test the rental at the drawn balance and at higher variable costs, not just today’s.
A bank’s investment-property line works differently. NerdWallet notes that lines on investment property come from a smaller pool of lenders, are not offered by all, and carry strict qualification requirements. That is how bank products behave. The network figures above are different: 70% CLTV on a second lien, no reserves, and no personal income calculation, subject to lender guidelines.
A Worked Scenario: Bridging a Renovation
Run the logic on a hypothetical investor who owns a leased duplex with a low-cost first mortgage. They want to fund a unit renovation, then sell or refinance within a limited window.
Say the first mortgage balance and the requested line together land near 60% of the property’s value. That sits under the 70% second-lien cap. Their credit score is above 720. Lease rent and the appraiser’s market rent are close, so the lesser of the two is easy to read.
The rent test is next. Suppose, for illustration, the stress payment on the full line produces coverage around 1.2x. That clears the 1.10x minimum. If the same file came back near 1.05x, the investor would need a smaller line, higher rent support, or a different structure. Qualifying arithmetic is illustrative, and the lender’s own calculation governs.
Because at least 80% of the line is drawn at closing, the investor should size the line to the real cost of the work, not to the maximum available. An oversized line means paying interest on money that is not working. They would also settle the exit before closing: a sale, a refinance after the renovation lifts rents, or paydown from cash flow.
The first mortgage never changes in this picture. That is the point of the structure.
Key Terms Defined
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 the lender tests.
Draw period: The stretch, 5 years on this program, when you pay interest only on what you have drawn.
Repayment period: The 25-year stretch after the draw period when the balance fully amortizes.
Second lien: A loan recorded behind the first mortgage, paid second if the property is sold or foreclosed.
Seasoning: The holding or ownership time a rental needs before it can be used as collateral.
Stress payment: The payment the lender tests coverage against, calculated on the whole credit limit at a higher assumed rate.
What Does the Investor Decision Look Like?
Start with one question: is the need truly temporary, and is the exit clear?
A DSCR HELOC tends to fit when the first mortgage is worth keeping, the property has real equity room, the rent covers the stress payment, and you can name how the drawn balance gets repaid. It tends to fit poorly when you need a fixed payment, a long runway, or a replacement for an unfavorable first mortgage. In those cases, a cash-out refinance or a closed-end second may be the better tool.
A short checklist helps:
- Is the combined leverage under 70% on a second lien after the new line?
- Does rent, the lesser of market rent or lease, clear 1.10x on a stress payment over the full limit?
- Is the rental seasoned, with 6 months since the last note date and 6 months on title?
- Can you absorb a variable-rate balance if costs move?
- Do you have a payoff path that does not depend on the line staying open?
If the answers are yes, the structure may suit the need. 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.
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.
Frequently Asked Questions
Can I keep my first mortgage and still get a DSCR HELOC?
Yes, that is how the structure works. The line is written as a standalone second lien behind the first mortgage you keep, so its balance, term, and payment stay unchanged. The line must fit under the 70% combined loan-to-value cap on a second lien, and the borrowers on the line need not be the borrowers on the first mortgage, subject to underwriting.
Can an LLC hold title on the line?
Yes, on an investment property, subject to program terms.
What if my need runs longer than expected?
The draw period is 5 years interest-only, followed by a 25-year repayment period and a 30-year maturity. If the need outlasts your plan, you can keep paying interest on the drawn balance, pay it down from cash flow, or refinance. Because the rate is variable, the carrying cost can change, so build in room.
Does the line hurt coverage on my next purchase?
On most files, a purchase loan reads the new property against its own payment, so the line’s payment is generally not in that ratio. The line does lower the coverage on the property that secures it. Confirm the treatment with the purchase lender before drawing.
