The Quick Read: A DSCR HELOC lets you borrow against a rental’s equity as a standalone second lien behind your fixed first mortgage, qualified primarily on the property’s rent covering the payment (subject to lender guidelines), and only a small group of wholesale lenders write it, so the right fit depends on your property. Lendmire is a mortgage broker, not a lender. It compares these programs across its wholesale network and matches your file to the one that fits.
- Your fixed first mortgage stays in place. The line sits behind it as a second lien.
- The rent qualifies the line. Typically, programs ask for 1.10x coverage on a stress payment, with no traditional personal-income documentation, W-2s, or personal income calculation.
- Second-lien leverage tops out at 70% combined loan-to-value, usually at a 720 credit score or better, on lines of $50,000 to $500,000, subject to underwriting.
- The line is a variable-rate product. Your first mortgage payment stays fixed, but the line’s payment can move.
- Your first mortgage documents, seasoning, and property type can stop a file even when the equity looks ample.
What a DSCR HELOC Is, and What It Isn’t
A DSCR HELOC is a revolving credit line secured by a rental you keep. It is written behind your first mortgage as a standalone second lien. It can also be a standalone first lien on a rental with no mortgage. It is never a third lien, never closes with a purchase, and never sits on your own home.
The name is a market label, not a standardized product. A bank’s rental HELOC and a rent-qualified line from a wholesale lender share a word and little else. NerdWallet notes that a HELOC on an investment property is possible. It also says lenders see higher default risk, the lender pool is smaller, and you can borrow less than against a primary home.
Here is the practical result. Many big banks and large retail lenders build their equity lines around the owner-occupied home and test your personal income and debts. Some decline rentals outright. A DSCR HELOC flips the test. The property’s rent has to cover the qualifying payment, and your personal income is not calculated.
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. Lendmire’s complete DSCR loans guide covers the basics if the acronym is still new.
Who Offers These? Lender Types Compared
Lenders that write a rent-qualified line behind a mortgaged rental are few, and no single lender fits every file. The useful comparison is by type, not by name. This table shows how the main routes differ.
| Route | What it tests | Fixed first stays? |
|---|---|---|
| Bank equity line | Your income and debts | Yes |
| Wholesale DSCR HELOC | Rent on the property | Yes |
| Closed-end DSCR second | Rent, fixed lump sum | Yes |
| DSCR cash-out refinance | Rent, replaces first | No |
Banks and credit unions that test the borrower often want the property titled in an individual’s name or a revocable trust. A wholesale DSCR line can allow an LLC on title for an investment property, subject to program terms. The members sign as guarantors, and the borrowers on the line need not be the borrowers on the first mortgage.
Which lenders write this for you depends on your property type, credit profile, leverage need, and how much rent the property earns. A broker that shops several wholesale lenders can compare their guidelines side by side. Most programs share a core structure. The overlays differ on property types, valuation, and how the coverage math treats the first mortgage. The program described here is offered in all 16 of Lendmire’s licensed states.
What Happens to Your Fixed First Mortgage?
Nothing changes on the first mortgage. Its rate, term, and payment stay as they are. A cash-out refinance replaces the first. A second-lien line leaves it alone. For an owner sitting on a low fixed first, that is the whole point.
Before you apply, read your first mortgage note and deed of trust. You are looking for two things: a due-on-sale clause and a no-further-liens covenant. A Wharton real estate paper on second liens explains that a federal due-on-sale law generally limits enforcement against a junior lien on residential property of fewer than five units. The statute and the contract are different risks. Your documents decide the second one.
Hazard insurance has to cover both liens. Flood coverage is required where the property needs it.
How Coverage Gets Tested on a Mortgaged Rental
Coverage is gross monthly rent divided by the qualifying payment. The program minimum is 1.10x, subject to underwriting. Three details decide the number.
1. The payment is a stress payment. It is a fully amortizing payment on the entire credit limit, calculated 2 percentage points above the line’s start rate. The test does not use your drawn balance. A big unused line still counts in full.
2. The rent is the lesser of two numbers. The lender takes either the appraiser’s Form 1007 market rent or the lease. A lease above market can count with three months of receipts.
3. A lease must be in place. A two-to-four-unit property may have at most one vacant unit.
Here is a modeled example, not a market fact. Say a rental clears the qualifying payment at 1.25x on a given limit. Raise that limit by 20%, and the payment rises by 20%. Coverage drops to about 1.04x, below the 1.10x minimum. Asking for more line can sink a file that works at a smaller size.
Whether the first mortgage payment joins the qualifying payment on a second lien is not something this program publishes. The lender’s own coverage calculation governs. Ask the lender how it treats the first payment before you apply. A thin-rent property can fall short even with plenty of equity, so this question matters.
Sizing the Line From Your Equity
Second-lien leverage is measured as combined loan-to-value (CLTV). That is your first mortgage balance plus the new line, divided by the property’s value. On a second lien, the program goes up to 70% CLTV at a 720 credit score or better, on lines up to $500,000, subject to underwriting. Below 720 there is no second-lien option. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
The sizing math has three steps:
1. Multiply the value by 70%.
2. Subtract your first mortgage balance.
3. Cap the result at the program maximum.
Picture a rental with a first mortgage equal to 50% of its value. A 70% CLTV cap leaves room for a line up to 20% of value. If the first balance is 60% of value, room shrinks to 10%. Lines start at $50,000, so a property with a heavy first balance may leave too little room to fit at all.
Compare the first-lien version. On a rental with no mortgage, leverage runs up to 75% LTV at 740 or better on lines to $500,000. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. The first-lien credit floor is 700. A declining-market flag on the property can lower the ceiling by 5 points. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Credit has other checks. Mortgage history should show no 30-day late in the last 12 months. Programs want 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu. The program asks for no reserves and no cash to close. It caps exposure at 5 loans or $2,500,000 per borrower.
Fixed First Plus a Variable Line: The Blended-Cost Picture
Your first mortgage payment never moves. The line’s payment can. The CFPB describes a HELOC as an open-end line that usually carries a variable rate, so payments can change from month to month. Only the line floats in this structure. That is a smaller exposure than refinancing everything into a variable product.
The line has a defined life. The draw period runs 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each.
Those draw rules change how the line behaves. A required draw at closing means it acts more like a loan than a standby reserve. The interest-only stretch keeps the carry light, then the payment steps up when repayment starts. Plan for that step-up before you draw. Plan for the variable movement too.
The blended picture is two payments of different character. One is steady and low, set when you bought or refinanced. The other is variable and tied to what you drew. When you test whether the rental can carry the pair, test the line’s payment at a worse level than today’s.
Eligibility Gates That Stop Files
Equity and credit are only part of the file. These gates stop more deals than most investors expect.
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).
Property type. Eligible properties include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums. Lots up to 10 acres also qualify. Rural-designated property, row homes, condotels, leaseholds, land trusts, and age-restricted communities fall outside this lane. So do mixed-use, commercial, and agricultural property, hobby farms, modular and log homes, and land contracts. A property listed for sale in the prior 2 months, or one with a solar lien, is also out.
Borrowers. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number qualify. Foreign nationals and ITIN borrowers do not.
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. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
Title. Second liens above $400,000 and all first liens get a full title policy. Smaller second liens use an owner-and-encumbrance report.
One practitioner-level note. Across wholesale programs, files rarely fail on the headline numbers. They fail on the quiet items: a note with a lien covenant, a listing that ended last month, a lease that does not support market rent. Run those checks first.
Which Route Fits Which Situation?
The line is one of three ways to reach equity on a mortgaged rental. This table lays out when each fits.
| Situation | Usual fit |
|---|---|
| Low fixed first, staged capital needs | DSCR HELOC |
| One known lump sum, fixed payment wanted | Closed-end second |
| First mortgage is expensive, big cash need | Cash-out refinance |
| Credit below 720, rental has a mortgage | Cash-out refinance or wait |
The decision rule is simple. If your first mortgage is worth keeping, keep it and add a second lien. If it is not, replace it. A line fits repairs, reserves, or a future down payment, where you draw in stages. A line does not buy the next property. A separate DSCR purchase loan does that.
Broker comparison matters here. Different wholesale lenders handle valuation, property types, and the first-payment treatment differently. A scenario that stalls with one program can fit another.
When This Is the Wrong Move
Skip the line when the rent is thin against the full limit. Skip it when you need a fixed payment you can plan around for decades. Skip it when your first mortgage note bars additional liens, because a signed covenant can outweigh strong numbers.
Also skip it if you would draw only the required minimum and pay interest on money you do not need. The 80% draw at closing makes that a real cost.
If you are declined, you have four paths. Ask for a smaller line, since coverage improves as the limit shrinks. Ask whether a closed-end second fits better. Look at a cash-out refinance if your first mortgage is not a prize. Or wait out a seasoning or listing-status issue and reapply. For borrowers who prefer the personal-income version, Lendmire’s piece on how an investment property HELOC qualified on your income works covers that route.
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.
What to Prepare, and What to Ask Any Lender
A mortgaged-rental file typically needs the lease or rent evidence, the first mortgage statement, a copy of the note and deed of trust, a credit report, and entity documents if an LLC holds title. The lender orders the valuation and title work.
Ask every lender these questions:
- How does your coverage calculation treat my first mortgage payment on a second lien?
- Is the stress payment run on the full limit or the drawn balance?
- What valuation path applies at my line size?
- Does my property type sit inside your guidelines?
- Can my LLC hold title, and who signs?
- What does the line’s payment do once repayment begins?
Key Terms Defined
DSCR (debt-service coverage ratio): Gross monthly rent divided by the qualifying payment. This program wants at least 1.10x.
CLTV (combined loan-to-value): Your first mortgage balance plus the new line, divided by the property’s value.
Lien position: The order in which lenders get repaid. A second lien sits behind the first.
Stress payment: The payment the lender uses to test coverage. It runs on the entire credit limit, with a cushion added above the line’s start rate.
Draw period: The 5-year stretch when you can borrow from the line and pay interest only on what you drew.
Negative pledge: A clause in some mortgage notes that bars additional liens on the property.
Frequently Asked Questions
Can I get a DSCR HELOC on a rental that already has a mortgage?
Yes, through select programs, as a standalone second lien behind your first mortgage. The rent has to cover the stress payment at 1.10x or better. The combined loan-to-value is capped at 70% at a 720 score or better. Everything remains subject to underwriting.
Do I need tax returns or W-2s?
Not for this program. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lender still documents the rent, the lease, your credit report, and the valuation.
Can my LLC hold title?
Often yes on an investment property, per program requirements. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Does the line replace my first mortgage?
No. Your fixed first stays exactly as it is. Only a cash-out refinance replaces the first mortgage.
What if my first mortgage restricts additional liens?
Then the file may stop, whatever the numbers say. Read your note and deed of trust before applying. If a covenant bars a second lien, your options are a refinance or a different route.
