The Quick Read: A DSCR HELOC is a revolving line written as a second lien behind the first mortgage you keep, and it qualifies primarily on the rental’s income covering the payment, subject to lender guidelines. No single provider is right for every owner. The right fit depends on your property, credit tier, combined leverage and how the title is held, which is why a broker that shops several wholesale lenders can narrow the field faster than calling lenders one at a time.
- The existing first mortgage stays untouched. The new line sits behind it.
- Qualification runs on rent, not on tax returns, W-2s or a personal debt-to-income ratio.
- Through select programs, a second lien reaches 70% combined loan-to-value at a 720 credit score or better, on lines up to $500,000.
- The coverage test uses a stress payment on the entire credit limit, not just the drawn balance. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Lendmire is a mortgage broker, not a lender. It does not rank or name lenders, so this page explains how these programs work and how to judge any provider. Everything below is subject to underwriting and is not a commitment to lend.
What Is a DSCR HELOC Behind Your First Mortgage?
A DSCR HELOC is a home equity line of credit on a non-owner-occupied one-to-four-unit rental. Through the programs Lendmire places, it is a standalone second lien behind the first mortgage you keep. It can also be a standalone first lien on a rental with no mortgage.
Your first mortgage is not paid off, resized or repriced. A cash-out refinance does that. A line simply adds a second loan to the same property.
The line is never closed together with a purchase. It is never a third lien, and it is never a line on your own home or a second home. A first-time investor buys the rental first and opens the line later. Vesting in your LLC is allowed on investment property, and the members sign as guarantors. The borrowers on the line need not be the borrowers on the first mortgage.
Key Terms Defined
DSCR (debt service coverage ratio): The rental’s gross monthly rent divided by the qualifying payment. A result above 1.00x means rent exceeds the payment.
Second lien: A loan secured by the same property that is paid after the first mortgage if the property is sold or foreclosed.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line. On this program it is 5 years of interest-only payments on the drawn balance.
Junior-lien clause: Language in your first mortgage documents that allows or restricts a second loan behind it.
How Does Underwriting Treat It, Step by Step?
The lender reads the file in a set order. Knowing that order tells you what to prepare.
1. Property check. The property must be a single-family home, PUD, townhome, two-to-four-unit building, or a warrantable or non-warrantable condominium. Lots up to 10 acres are also eligible. A lease must be in place, and a two-to-four-unit building may have at most one vacant unit.
2. Lien position. If you keep a first mortgage, the line is a second lien and the 720 credit floor applies. If the rental has no mortgage, the line can be a first lien with a 700 floor.
3. Leverage. The lender adds the first mortgage balance and the line, then divides by value. The tiers appear in the next section.
4. Rent. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market.
5. Coverage test. The minimum is 1.10x. The qualifying 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. Taxes and insurance are not part of it.
6. Valuation. Lines up to $400,000 use an automated valuation with a confidence score of 85 or better, plus a property inspection report. A full interior appraisal is the other option. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
7. Credit and history. Underwriters want no 30-day mortgage late in the last 12 months. They also want 48 months since any bankruptcy, foreclosure, short sale or deed-in-lieu.
8. Title and 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).
No reserves and no cash to close are required, subject to underwriting. Each borrower is limited to 5 loans or $2,500,000 with the program.
One point on a second lien is not published: whether the first-mortgage payment joins the qualifying payment. Confirm on the file how the lender treats it. The lender’s own calculation governs, and any arithmetic here is illustrative.
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.
What Leverage, Line Size and Draw Rules Apply?
The program is built from a few tiers. These are ceilings, not offers, and all are subject to underwriting.
| Lien position | Score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien (CLTV) | 720+ | 70% | $50,000 to $500,000 |
| First lien (LTV) | 740+ | 75% | Up to $500,000 |
| First lien (LTV) | 700 to 739 | 70% | Up to $500,000 |
| First lien (LTV) | 720+ | 65% | Above $500,000 to $1,000,000 |
There is no second-lien cell below a 720 score. A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
At least 80% of the line is drawn at closing, and that 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.
The draw period is 5 years of interest-only payments on the drawn balance. A 25-year fully amortizing repayment period follows, and maturity is 30 years. The rate is variable, and the rate and pricing terms come with the lender’s disclosures.
Which Provider Types Can Write This?
Two kinds of providers might put a line on a rental you already finance. They differ mostly in how they qualify you, so this table compares provider types rather than companies.
| Factor | Wholesale DSCR HELOC (via broker) | Bank or credit union rental HELOC |
|---|---|---|
| Reviewed around | The rental’s rent | Personal credit, income, DTI |
| LLC on title | Allowed on investment property | Often blocked |
| How many options | Several lenders shopped at once | One lender per application |
Bank and credit-union lines on rentals exist but are scarce. Investors on BiggerPockets describe calling around to find one, and some lenders limit the line to a single investment property. A large retail lender may also decline rentals outright.
A wholesale DSCR HELOC lender works only through brokers and qualifies the file on rent. Lendmire’s network of wholesale lenders is where this program lives. For a deeper look at how the program compares, see Lendmire’s piece Best DSCR HELOC Program While Keeping the Existing First Mortgage in Place.
How to Judge Top DSCR HELOC Providers
“Top” depends on your situation, so use criteria instead of a ranked list. A provider that suits a 740-score owner with an unencumbered duplex may not suit a 722-score owner with a first mortgage on a condominium. Ask each one:
- Does it write a second lien behind my current first mortgage, and at what combined leverage?
- Does it allow my LLC on title, with members signing as guarantors?
- How does it test coverage, and does the first-mortgage payment join the qualifying payment on a second lien?
- Does the line size fit, given the $50,000 floor and the 80% closing draw?
- Does my property type sit inside the program, or outside it?
- Which valuation path applies at my line size?
Lendmire’s role is to match a file to the lender whose guidelines it fits, because it sees several lenders’ overlays side by side. The strictest overlays tend to hit property type, seasoning and declining-market flags.
Keep the First Mortgage or Replace It?
The table below shows how three structures treat the first mortgage. The right one depends on how much money you need and what your first mortgage looks like.
| Factor | DSCR HELOC | Personal-income rental HELOC | DSCR cash-out refinance |
|---|---|---|---|
| First mortgage | Stays | Stays | Replaced |
| Reviewed on | Rent | Personal income | Rent |
| Payment on first | Unchanged | Unchanged | Reset into a new loan |
| Best when | You want staged access to equity | You have strong traditional employment income and a willing bank | You need a large lump sum |
Keeping the first makes the most sense when its terms are worth protecting and your need comes in stages, such as renovations or down payments on later deals. A cash-out is usually the better fit when you need one large sum, when your first mortgage is weak, or when the property falls outside the HELOC’s eligibility box.
A Worked Example in Percentages and Ratios
Picture an owner with a single-family rental held in an LLC. The first mortgage balance is about 50% of value, and the owner holds a 735 credit score. This is a modeled scenario, not market data. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Adding a line equal to 20% of value brings combined leverage to 70% CLTV. That matches the second-lien ceiling at the 720 tier. Nothing else is available on the leverage side. A 700-to-719 borrower has no second-lien tier at all, so the owner would need a higher score.
On the coverage side, say the lease and the appraisal’s market rent both land at the same figure. The qualifying payment is the stress payment on the entire limit, even though 80% is drawn at closing. If rent covers that payment at roughly 1.2x, the test clears the 1.10x minimum. If it lands closer to 1.05x, the owner can shrink the line. That lowers the stress payment and lifts the ratio. The lender’s own calculation governs.
That is why owners sometimes take less than the maximum. The coverage number often binds before the leverage ceiling does.
Where the General Rule Breaks
These are the edge cases that change the answer.
- No mortgage on the rental. The line becomes a first lien, with different credit floors and leverage caps. The 700 floor and 70% cap apply.
- A keeper first mortgage at 700 to 719. Only a second lien is possible for someone who keeps a first mortgage, and its floor is 720. The obstacle is the score, not lien position.
- First mortgage that is itself a non-QM or DSCR loan. The junior-lien question matters more here, so read the note before you apply.
- Property outside the box. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use properties, a property listed for sale in the prior 2 months, and a property with a solar lien are all outside this lane.
- 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.
- Short-term rentals. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
- Risk. A line is open-end credit, which the CFPB explains in plain terms. The same source warns that falling behind could cost you the property that secures it. Here that means the rental, which already carries a first lien.
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.
Pre-Checks and Documents Before You Apply
Do these checks first, because they decide whether the file can move forward at all.
1. Read your first mortgage note for a junior-lien restriction. If it is unclear, ask your servicer.
2. Confirm both six-month clocks are satisfied.
3. Confirm the property type is eligible and the property is not listed for sale.
4. Confirm title and vesting, and plan for any title holder who is not a borrower to sign a non-borrowing owner acknowledgment and the security instrument.
5. Run a quick coverage check using the lease, expected market rent and the stress-payment logic.
Then gather these documents:
- the current lease
- the first-mortgage statement
- LLC documents if the property is entity-held
- hazard insurance covering both liens, plus flood coverage where required
- credit authorization

When This Is the Wrong Move
A DSCR HELOC is the wrong tool in a handful of situations.
- You want it to fund the purchase of the same property. It cannot.
- You need money in a single large sum. A cash-out is the product built for that.
- Your plan depends on keeping most of the line unused. At least 80% is drawn at closing.
- Your rent barely clears 1.00x. Variable-rate risk and the end of the interest-only draw period could push coverage below the program minimum. Stress your own numbers before you commit.
- You are in a state outside the footprint. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Frequently Asked Questions
Does a DSCR HELOC replace my first mortgage?
No. It is a separate loan secured behind the first, so the first mortgage keeps its current balance and terms. The product that replaces the first mortgage is a cash-out refinance. Many owners confuse the two because both draw on equity.
Can I buy my first rental with a DSCR HELOC?
No. This line is never closed together with a purchase, and it cannot fund the property it sits on. A line on your own home used to buy a rental is a different, personal-income product.
How long must I own the property before applying?
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).
Does the first-mortgage payment count in the coverage test?
On a second lien, confirm on the file how the lender treats it. The program tests rent against a stress payment on the entire line, covering principal and interest only. The lender’s own calculation governs, so ask before you assume.
Which provider is best for my situation?
That depends on property type, credit tier, how much leverage you need, how the title is held and whether you keep a first mortgage. A broker that shops several wholesale lenders can match the file to the program whose guidelines fit it.
