The Quick Read: A DSCR HELOC is a home equity line on a rental, written as a standalone second lien behind the first mortgage you keep. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and the first loan is never touched. The gates are credit, combined leverage, valuation, seasoning, and whether your first loan allows a second lien.
- Second-lien leverage tops out at 70% combined loan-to-value (CLTV), at a 720 credit score or better, on lines from $50,000 to $500,000.
- The rent must cover a stress payment on the entire credit limit at 1.10x or better.
- The line requires no traditional personal-income documentation, W-2s, or personal income calculation, and no reserves, subject to underwriting.
- Six months of seasoning applies, and rural property, condotels, row homes, and leaseholds are out.
- Lendmire offers the line in 15 of its 16 licensed states, every licensed state except Tennessee. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
You have a DSCR first mortgage you like. Maybe the terms are good, maybe the prepayment clock is still running, maybe you simply don’t want to reset anything. You also want the equity in that rental. A second-lien line lets you reach it without replacing the first loan.
This guide walks through how the product works, how underwriting treats it step by step, the structures that exist, and where the general rule breaks. It comes from files placed through Lendmire’s wholesale network. Lendmire is a broker: it arranges these lines, and the lender underwrites and approves them. For the broader picture of how investor loans work, see the complete DSCR loans guide.
Key Terms Defined
DSCR (debt service coverage ratio): the rent divided by the monthly payment the lender uses to test the property. Above 1.00x, the rent covers that payment.
HELOC: a home equity line of credit, a revolving line secured by property that you draw from as needed.
Second lien: a loan recorded behind the first mortgage. In a sale or foreclosure, it gets paid second.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Seasoning: the waiting period a lender requires after you buy or refinance before you can borrow again.
Draw period: the stretch when you can pull money from the line. After it ends, repayment begins.
What Is a DSCR HELOC, Exactly?
It is a revolving line on a non-owner-occupied one-to-four-unit rental, qualified on the rent instead of your personal income. It is written one of two ways: as a standalone second lien behind a first mortgage you keep, or as a standalone first lien on a rental with no mortgage.
Three things it is not. It 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 primary-residence HELOC is a different, owner-occupied product.
“DSCR HELOC” is a market label, not a standardized product. Some lines sold under that name qualify on rent. Others qualify on your personal income. Ask which underwriting path you are being offered before you spend time on an application.
Title can stay in your LLC, subject to program terms. The members sign as guarantors. A title holder who isn’t a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line don’t have to match the borrowers on the first mortgage.
How Does Underwriting Treat the Line, Step by Step?
Underwriting runs in a fixed order, and each step can stop the file. Here is the sequence a lender follows.
Step 1: Eligibility of the borrower and property. Borrowers are U.S. citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. The property must be a single-family home, PUD, townhome, two-to-four-unit building, or a warrantable or non-warrantable condominium, on a lot of up to 10 acres.
Step 2: Credit. A second lien needs a 720 score or better, using the lender’s own credit report. Expect no 30-day mortgage late in the last 12 months. Expect a 48-month wait after a bankruptcy, foreclosure, short sale, or deed-in-lieu. Extra tradeline rules are waived at 700 and above, so a 720 score on a second lien clears them.
Step 3: 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 you must have held title for 6 months (settlement date to note date).
Step 4: Valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal. Appraisal waivers are not accepted. The appraiser’s rent schedule, Form 1007, also feeds the coverage test.
Step 5: Combined leverage. The lender adds your first-mortgage balance to the new line and divides by value. On a second lien, that number tops out at 70% CLTV, subject to underwriting.
Step 6: The coverage test. This is where the rent gets used, and it deserves its own section.
Step 7: Title and insurance. A second lien above $400,000 gets a full title policy. Smaller second liens use an owner-and-encumbrance report. Hazard insurance must cover both liens, with flood coverage where required.
How Does the Coverage Test Work With a First Mortgage Already in Place?
The rent must reach at least 1.10x of a qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit, calculated at a stress rate set above the start rate. Taxes and insurance are not part of it.
The size of the line matters, not the amount you draw. A $300,000 limit is tested as if it were fully borrowed. Drawing less later does not change the test.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required. A two-to-four-unit property can have at most one vacant unit.
One question every borrower asks: does the first-mortgage payment also go into the qualifying payment on a second lien? Confirm on the file how the lender treats the first-mortgage payment. The lender’s own coverage calculation governs, and any example here is illustrative only.
Picture a duplex whose rent covers the stress payment on a mid-sized line with a little cushion. If a lender also layers in the first payment, the same rent might fall short. That’s why you ask the question before you order anything.
What Do the Tiers and Terms Look Like?
On a second lien, there is one tier: 720 or better gets up to 70% CLTV, on lines from $50,000 to $500,000. Below 720, there is no second-lien cell on this program.
A first lien exists only on a rental with no mortgage. It runs up to 75% loan-to-value (LTV) at 740 or better and 70% from 700 to 739, on lines up to $500,000. Lines above $500,000, up to $1,000,000, are capped at 65% LTV at 720 or better. If you are keeping a first mortgage, none of the first-lien figures apply to you. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The table lays out the structure.
| Feature | Second lien | First lien |
|---|---|---|
| Applies when | You keep a first mortgage | Rental has no mortgage |
| Minimum credit | 720 | 700 |
| Top leverage | 70% CLTV | 75% LTV (740+) |
| Line size | $50,000 to $500,000 | Up to $1,000,000 |
| Lines above $500,000 | Not available | 65% LTV cap |
Every figure is a ceiling or floor subject to underwriting, not an offer. A declining-market flag lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
The line itself works like this:
- A 5-year interest-only draw period on the drawn balance.
- A 25-year fully amortizing repayment period, with a 30-year maturity.
- A variable rate. The rate and pricing terms come with the lender’s disclosures.
- At least 80% of the line is drawn at closing, never less than $50,000. On the smallest lines, that means the whole line.
- Later draws are at least $5,000 each.
That draw rule changes the pitch. This is not a standby line you open and leave idle. If you want a large unused cushion, this is the wrong tool.
Can Your First Mortgage Carry a Second Lien?
This is the gate most investors skip, and it can stop everything. The coverage test and leverage don’t matter if the first loan’s documents forbid more debt on the property.
Start with the due-on-sale clause. Federal law generally makes these clauses enforceable. But for residential property with fewer than five dwelling units, the statute at 12 U.S.C. § 1701j-3 limits a lender’s ability to call the loan when a subordinate lien is created. The implementing rule, 12 CFR 191.5, lists the protected events, and the official CFR text confirms the subordinate-lien exception does not cover a transfer of occupancy rights.
Read that carefully, because it has limits. It protects against a due-on-sale call. A separate covenant in your note or deed of trust against further encumbrances is a different animal. Whether the protection extends to a business-purpose investor note is something to confirm with counsel. Treat the federal rule as a backstop, not permission.
So pull your first-loan documents and check three things:
1. Any due-on-sale language.
2. Any covenant restricting additional liens.
3. Whether your servicer wants notice or consent.
If the documents are silent or permissive, you are clear on this gate. If they restrict a second lien, stop and get the servicer’s position in writing before you apply.
Where Does the General Rule Break?
The rule, “rent qualifies it and the first loan stays,” has named exceptions.
Moving title to an LLC. Putting a property into or out of an LLC to qualify is itself a transfer. The federal protections list family and estate transfers and a subordinate lien that doesn’t move occupancy, per a plain-language summary of the exceptions. Entity transfers aren’t on it. If your rental already sits in an LLC, the line can be written there. If it doesn’t, retitling just to qualify can trip the first loan’s clause.
Five or more units. Buildings this size fall outside the rule rather than inside it. The federal limits apply to fewer than five dwelling units, and this line is a one-to-four-unit product, so neither applies.
Leasehold, row home, condotel, rural. These property types are outside the program entirely. So are land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use properties, and commercial or agricultural property.
Recent listing or solar lien. A property listed for sale in the prior 2 months is out. So is a property with a solar lien.
Borrower exposure. The program caps a borrower at 5 loans or $2,500,000 total. A larger portfolio can hit that ceiling before any single property does.
A later refinance of the first. A new first lien needs the junior holder to subordinate, or the line must be paid off. Not every junior lender will agree, so plan this before you take the line.
Short-term-rental listings. 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. A listing history can also affect how a lender classifies the property.
What Does the Combined-Leverage Math Look Like?
Say you own a rental valued at $500,000 with a first mortgage balance equal to 45% of value. At 70% CLTV, you have 25 points of value to work with. That is the maximum new line, before any other limit applies.
Now run a tighter case. A rental valued at $500,000 with a first balance at 66% of value leaves only 4 points of room. That is far below the $50,000 minimum line, so there is no second-lien fit at all. These are modeled assumptions, not market data.
The formula is the same either way: first balance plus the new line, divided by value, must stay at or under the ceiling. Because your first balance counts against it, equity runs out faster than most investors expect. Newer loans on recently bought property leave the least room.
HELOC, Cash-Out Refinance, or Something Else?
A second-lien line leaves your first loan in place. A cash-out refinance replaces it. The right choice depends on what your first loan is worth keeping and how much cash you need. Lendmire’s piece DSCR HELOC vs DSCR Cash-Out Refinance Behind a DSCR First Mortgage You Want to Keep goes deeper on the tradeoffs.
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| First mortgage | Stays untouched | Replaced |
| Structure | Revolving, variable rate | New first loan |
| Cash at closing | At least 80% of line drawn | Per loan terms |
| Best when | First loan is worth keeping | First loan is not |
Other products behave differently. A bank statement HELOC is reviewed on bank deposits. An investment-property HELOC qualified on personal income uses your income file. Those are those programs’ rules, not this one’s.
Keeping the first loan makes sense when its terms are strong, its prepayment clock is still running, or its remaining term suits you. Replacing it makes sense when you need more cash than a second lien allows, or when the first loan is a poor fit anyway.
When Is This the Wrong Move?
Skip it in these cases:
- You want a large undrawn cushion. At least 80% of the line is drawn at closing.
- Your score is below 720 and you are keeping a first mortgage. There is no second-lien cell.
- Your rental was bought or refinanced in the last 6 months.
- Equity is thin after your first balance is counted.
- The rental has no lease in place.
- Your first loan restricts additional liens and the servicer won’t budge.
- The property is rural, a row home, a condotel, or a leasehold.
A common mistake is chasing a line before checking the first loan’s documents. Another is assuming the variable rate and the 5-year interest-only window will feel the same in year six. When repayment begins, the drawn balance amortizes over 25 years, and the payment steps up accordingly.
Pre-Application Checklist
Go in this order. Each item is a stop-or-go gate.
1. Pull your first-loan note and deed of trust. Look for due-on-sale and additional-lien language. 2. Confirm title and vesting. Don’t retitle just to qualify. 3. Calculate CLTV with your first balance and the line you want. 4. Check seasoning: 6 months since the last note date and 6 months on title. 5. Confirm your credit tier from a lender’s report. 6. Gather the lease, rent evidence, insurance declaration, and first-mortgage statement. 7. Ask how the lender treats the first-mortgage payment in coverage. 8. Check eligibility: property type, state, and listing history.

Frequently Asked Questions
Can I add a HELOC to a rental that already has a DSCR first mortgage?
Often, yes, if your credit, equity, and the first loan’s documents allow it. The line is written as a standalone second lien behind your first mortgage. You need a 720 score or better, and combined leverage is capped at 70% CLTV. Everything is subject to lender guidelines and underwriting.
Does my first lender have to approve a second lien?
Not always, but check. Federal rules limit a lender’s ability to call a loan when a subordinate lien is created on a one-to-four-unit residential property. Your note may still carry a separate covenant on further liens. Read the documents and ask the servicer for its position in writing.
Can an LLC-owned rental get one?
Yes, subject to program terms. The LLC can hold title, the members sign as guarantors, and the property must be investment property. Moving title into the LLC just to qualify is a different matter, because a transfer can trigger the first loan’s due-on-sale clause.
Does the new payment count against my coverage?
The qualifying payment is principal and interest on the entire credit limit at a stress rate, and the rent must reach 1.10x. Whether your first-mortgage payment joins that calculation is something to confirm on the file. The lender’s own calculation governs.
How soon after buying or refinancing can I apply?
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).
