The Quick Read: A DSCR HELOC is a revolving credit line written as a standalone second lien behind the first mortgage you keep, or as a first lien on a rental with no mortgage, and it qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Your first loan keeps its own rate and term. Only the new line is underwritten.
- Lien position: a standalone second lien behind your kept first mortgage, or a standalone first lien on a paid-off rental. It never closes together with a purchase.
- Qualifying: minimum DSCR of 1.10x, tested on a stress payment over the whole line. No traditional personal-income documentation, W-2s or personal income calculation, subject to underwriting.
- Leverage: on a second lien, up to 70% combined loan-to-value at a 720 score or better, on lines up to $500,000, through select programs.
- Structure: a 5-year interest-only draw period, then a 25-year repayment period, with a 30-year maturity and a variable rate.
- Footprint: offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What Does “Without Refinancing the First Lien” Actually Mean?
It means the loan already on your rental stays exactly as it is. The new line is recorded behind it as a separate lien. The lender on the line only cares about the equity left over and the rent coming in.
A cash-out refinance works the opposite way. It pays off the first mortgage and replaces it with a bigger one, so the whole balance takes on new terms. A line only adds new terms to the new borrowing.
That difference matters most when your existing first mortgage is worth keeping. Many investors hold a first loan they would not want to replace. A second lien lets them reach equity without touching it.
There are two versions of this structure:
1. Second lien. You keep a first mortgage, and the line sits behind it.
2. First lien. The rental has no mortgage, and the line is the only loan on it.
Across the wholesale network Lendmire works with, this product is a standalone line. It is never a third lien. It is never a line on your own home or a second home. It applies only to non-owner-occupied one-to-four-unit rentals.
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.
Key Terms Defined
DSCR (debt service coverage ratio): the property’s gross monthly rent divided by the qualifying payment. A result of 1.10x means rent is 10% larger than that payment.
Second lien: a loan recorded after the first mortgage. If the property is ever sold or foreclosed, the first lender is paid first.
Combined loan-to-value (CLTV): your first mortgage balance plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line and pay interest only on what you have drawn.
Seasoning: the waiting period a lender wants after you buy or refinance a property before it will lend against it.
Stress payment: a fully amortizing payment, calculated on the entire credit limit at a higher test rate. It is used only to test coverage, and it is not your actual payment.
How Is a DSCR HELOC Underwritten, Step by Step?
The rent qualifies the line. That is the core idea. Here is the sequence a lender works through, subject to underwriting.
Step 1: Confirm the lien position. The lender checks that the line will sit directly behind your first mortgage, or alone in first position.
Step 2: Establish the rent. Rent counts as the lesser of two numbers. One is the appraiser’s market rent on Form 1007. The other is the lease. A lease above market can count only with three months of receipts. A lease in place is required, and a two-to-four-unit property may have at most 1 vacant unit.
Step 3: Build the stress payment. The lender calculates a fully amortizing payment on the entire credit limit, using the start rate plus 2 percentage points. The test covers the whole line, not just what you draw. Because of that, a line you only half use is still tested at full size.
Step 4: Run the coverage test. Gross monthly rent divided by that stress payment must reach a minimum of 1.10x. Whether your first-mortgage payment joins the qualifying payment on a second lien is set by the lender’s own coverage calculation. Treat that as a question to ask early, because lenders do not all calculate coverage the same way.
Step 5: Size the line against value. The lender adds your first mortgage balance and the new line, then divides by value. That combined figure must fit under the leverage cap for your credit tier.
Step 6: Check the personal file. Credit is still reviewed. So are mortgage history, title and insurance. What is skipped is the personal income file: no traditional personal-income documentation, W-2s, pay stubs or debt-to-income ratio.
A Worked Example, Without the Dollar Signs
Picture a rental whose appraisal comes in at 100 units of value. Your first mortgage balance is 45% of that value. You have a 740 credit score. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
On a second lien at that score, combined leverage can reach 70%, subject to underwriting. Subtract the 45% first mortgage from the 70% ceiling, and the room is 25% of value. The line must also fit inside the program’s size range, from $50,000 up to $500,000.
Now the coverage test. The lender takes the lesser of market rent or lease. It builds the stress payment on the full 25%-of-value limit. If rent divided by that payment lands at 1.10x or higher, the property clears the test.
Say rent lands around 1.3x. The file has room to spare. Say it lands around 1.0x. The usual fix is a smaller line, since a smaller limit shrinks the stress payment. Lowering the line to fit the rent is more common than raising the rent to fit the line.
All of this is illustrative. The lender’s own calculation governs every file.
What Leverage and Credit Tiers Apply?
The figures below are ceilings and floors, subject to underwriting. They are not offers.
| Position | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien | 740 or better | 75% LTV | Up to $500,000 |
| First lien | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
Note that second-lien leverage is written as CLTV and first-lien leverage as LTV. Also note that a second lien has no cell below a 720 score. A first lien starts at 700.
A few more points shape the ceiling:
- A flag for a declining market lowers the ceiling by 5 points.
- Philadelphia lines carry a ceiling 10 points lower.
- No reserves and no cash to close are required.
- Mortgage history must show no 30-day late payment in the last 12 months.
- The program waits 48 months after a bankruptcy, foreclosure, short sale or deed-in-lieu.
- One borrower can have at most 5 loans or $2,500,000 with the program.
How Does the Line Behave After Closing?
A DSCR HELOC works like a credit line for the first five years, then like an amortizing loan.
At least 80% of the line is drawn at closing, and never less than $50,000. After that, each draw is at least $5,000. During the 5-year draw period you pay interest only on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable.
Variable means your payment can change even if you never draw again. The CFPB’s explainer on home equity lines also notes that a lender may stop additional credit if the home’s value drops significantly. So an undrawn balance is not a guaranteed pool of cash. It is a poor substitute for real reserves.
The rate and pricing terms come with the lender’s HELOC disclosures. A passing DSCR also does not mean the property throws off positive cash flow. The coverage ratio uses gross rent and a stress payment, not your real operating costs.
What Property and Borrower Rules Apply?
The line fits single-family homes, planned unit developments, townhomes, two-to-four-unit properties, and warrantable and non-warrantable condominiums. Lots up to 10 acres are eligible.
These property types fall outside this lane:
- 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 buildings
- a property listed for sale in the prior 2 months
- a property with a solar lien
Seasoning comes next. 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).
Eligible borrowers are US citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible on this program.
Valuation depends on line size. Lines up to $400,000 can use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted. Hazard insurance must cover both liens, plus flood coverage where required. The title policy is a full policy on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report.
Can an LLC Hold Title, and Do the Borrowers Have to Match?
Vesting in your LLC is allowed on this investment-property line, subject to program terms. The LLC members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
The borrowers on the line also need not be the borrowers on the first mortgage. That surprises people, because a bank-style line usually follows the same names as the first loan.
Where Does the General Rule Break?
Most surprises live in the edge cases. These are the ones worth checking before you apply.
The label covers different products. “Rental HELOC” can mean two things. One is a bank-style line that reviews you: credit, income and debt ratios. The other is the rent-qualified line described here. NerdWallet notes that a HELOC on an investment property is not offered by all lenders, and qualification requirements can be strict. Some products sold under this name are also closed-end seconds that pay out one fixed amount. Ask whether the line is truly revolving.
Your first mortgage may restrict junior liens. Read your first mortgage documents before you apply. Some first loans limit additional liens on the property, which is a real concern when the first loan is itself a DSCR loan. Confirm with your servicer or an attorney.
Refinancing the first loan later takes permission. If you refinance the first mortgage down the road, the new first lender will not accept second position. The line’s lender must then sign a subordination agreement. That decision turns largely on the new combined leverage. If the new first loan plus the line pushes the ratio too high, the junior lender may decline.
A zero balance does not remove the lien. The lien stays until the line is formally closed and released.
Shared exposure caps. Because one borrower is limited to 5 loans or $2,500,000 with the program, a larger portfolio can hit the ceiling before the property does.
Coverage depends on how the lender counts the first payment. If a lender folds your first mortgage payment into the test, a second lien needs much more rent. If not, the test is easier. That is why lenders in the network can answer the same file differently.
How Does It Compare With the Alternatives?
| Factor | DSCR HELOC | Cash-out refinance | Bank-style HELOC |
|---|---|---|---|
| Lien on first mortgage | Kept in place | Replaced | Kept in place |
| Funds | Revolving draws | One lump sum | Revolving draws |
| Reviewed on | Rental coverage | Rental coverage (DSCR version) | Your personal income |
| Rate applies to | Borrowed amount only | Entire balance | Borrowed amount only |
The first-mortgage rate matters here. A cash-out reprices the whole balance, while a line adds a separate variable rate to the amount you borrow. A closed-end lump-sum second works like the line in lien position but pays out once, with no revolving draws.
When Is This the Right Tool?
This is where the investor decision lives. The stronger play is usually the line when you hold a first mortgage you like and want flexible access to equity. A refinance wins when the first loan is poor and replacing it is a goal in itself.
| Your situation | Likely better fit |
|---|---|
| Favorable first mortgage, want revolving access | DSCR HELOC |
| First mortgage worth replacing | Cash-out refinance |
| Need one fixed lump sum | Closed-end second or cash-out |
| Thin rent coverage on the property | Smaller line or another structure |
| Rental bought or refinanced recently | Wait out the seasoning clocks |
Common uses are down payments, rehab and paying off other debt. Because the line sits on a rental you already own, it adds debt to that asset. The line cannot close with a purchase, so the order is to close it first, draw, and then buy. Your cash from draws does not make the next property’s coverage test easier. That test centers on that property’s own rent.
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.
Before you apply, watch for these common mistakes:
- Sizing the line to maximum leverage instead of what the rent supports.
- Treating the undrawn balance as emergency money.
- Skipping a read of the first mortgage documents.
- Forgetting that variable payments can rise after the draw period.
What Does the Process Look Like?
The sequence is simple:
1. Pull your first mortgage statement and your current lease.
2. Gather entity documents if an LLC holds title.
3. Share a credit authorization so the lender’s own report sets your tier.
4. Order the valuation, whether the automated path or a full appraisal.
5. Complete title and insurance for both liens.
6. Sign the loan documents and review the HELOC disclosures.

Frequently Asked Questions
Will the line change my first mortgage?
No. The first loan keeps its own terms, and the new line is recorded behind it. The CFPB describes a HELOC as a second mortgage you pay in addition to your first. Your first payment is unchanged, though a second lien does add a payment of its own.
Can my first loan block a second lien?
It can. Some first mortgages restrict additional liens, so read the note and deed before applying. A servicer or attorney can confirm what yours allows.
Does the line count against the next property I buy?
The next purchase is qualified on that property’s own rent. How other debt is treated varies by program, so confirm it before you plan the sequence. The line cannot close together with a purchase, so it must come first.
Is an undrawn line a good reserve?
Not a safe one. A lender can stop further draws if the home’s value falls significantly. Keep real cash reserves alongside the line.
Can my LLC be the borrower on the line?
Yes, subject to program terms. Vesting in your LLC is allowed on an investment-property line. The members sign as guarantors, and a non-borrowing title holder signs an acknowledgment.
