The Quick Read: A DSCR HELOC is a revolving line of credit recorded as a standalone second lien behind the first mortgage you keep, and it qualifies primarily on the rental’s income covering a stress payment on the whole line, subject to lender guidelines. Your first mortgage keeps its balance, terms and maturity. The lender does not calculate your personal income, though credit, title and the property still get a full review.
- The line sits behind your first mortgage as a second lien, with combined leverage up to 70% CLTV at a 720 credit score or better, subject to underwriting.
- Rent must cover the payment on the entire credit limit at 1.10x or better, not just the amount you draw.
- If your first mortgage is itself a DSCR loan, its documents must allow a junior lien. Check that first.
- Lines run from $50,000 to $500,000 on a second lien, and the program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
What Is a DSCR HELOC, Exactly?
A DSCR HELOC is a home equity line of credit on a rental, qualified on the property’s rent instead of your paycheck or tax returns. DSCR means debt service coverage ratio: the rent divided by the monthly payment the lender tests. Different lenders use the term loosely, so here is the definition Lendmire’s programs use.
The line is secured by a non-owner-occupied one-to-four-unit rental that you keep. It is written one of two ways. If the rental has a mortgage you want to keep, the line is a standalone second lien behind it. If the rental is paid off, the line is a first lien on the property.
Three things it never is. It is never closed together with a purchase. It is never a third lien. It is never a line on your own home or a second home.
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.
Does the Line Leave Your First Mortgage Alone?
Yes. Lien position follows recording order, and your existing mortgage was recorded first. So the new line records behind it and is, by definition, a second lien. Your first loan keeps its balance, its payment schedule and its maturity.
This clears up a common mix-up. Many owners assume the new line has to replace the first mortgage. It does not. Replacing it is what a cash-out refinance does, and that is a different product.
The borrowers on the line also need not be the borrowers on the first mortgage. The line’s own terms still apply to whoever signs it. Say the rental sits in an LLC. Vesting in your LLC is allowed on investment property under this program, with the members signing as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. That is subject to lender program eligibility.
The Requirements at a Glance
Here are the verified figures for a second lien behind a kept mortgage, next to the first-lien version for a paid-off rental. All of it is through select programs and subject to underwriting. These are ceilings and floors, not offers.
| Factor | Second lien (mortgage kept) | First lien (no mortgage) |
|---|---|---|
| Max leverage | Up to 70% CLTV | 75% LTV at 740+; 70% at 700-739 |
| Minimum score | 720 | 700 |
| Line size | $50,000 to $500,000 | To $500,000; larger lines to $1,000,000 |
| Larger-line leverage | Not available | 65% LTV at 720+ above $500,000 |
Credit has more detail. The tier is based on the lender’s own credit report. You need no 30-day mortgage late in the last 12 months. You also need 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. Tradeline-depth rules are waived at 700 and above, and every tier here meets that score.
If you keep a first mortgage, the second-lien column is the only one that applies to you. A 700-to-719 score with a kept mortgage falls below the 720 second-lien floor, so a different product, such as a cash-out refinance, is the route to look at.
How Does Rent Qualify the Line With a First Mortgage in Place?
The lender tests the rent against a stress payment, and the test covers the whole credit limit. The qualifying payment is a fully amortizing principal-and-interest payment on the entire limit, calculated at the starting rate plus 2 percentage points. Taxes and insurance are not part of it. Gross monthly rent divided by that payment must reach 1.10x.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The appraiser’s market rent comes from the Form 1007 rent schedule. A lease in place is required. A two-to-four-unit property can have at most one vacant unit.
Why the full limit matters. The test does not care how much you draw. A bigger line means a bigger qualifying payment, so coverage falls as the limit rises. Picture rent that clears 1.10x at one line size. If the line grows by a fifth, coverage drops to about 0.92x and the file fails. That is illustrative arithmetic only, and the lender’s own calculation governs.
So the sizing works backward from rent. Start with what the rent can support at 1.10x, then see if that line size fits your equity.
The open point on the first mortgage. On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. Do not assume it is in or out. Ask for the answer before you count on a line size.
How Much Can You Actually Borrow? The CLTV Room Math
Lenders add your first mortgage balance and the new line, then divide by the property’s value. That is combined loan-to-value, or CLTV. Your room is the CLTV ceiling times value, minus what you still owe on the first mortgage.
Run the numbers on a rental with a first mortgage at 40% of its value. A 70% ceiling leaves room for a line equal to 30% of value. With a first mortgage at 60% of value, the room shrinks to 10% of value.
Now the catch. You can have real equity and still miss the program. Lines start at $50,000, and at least 80% of the line is drawn at closing. On the smallest lines, that means the whole line is drawn at the start. If your room falls under the minimum line on a lower-value rental, the line does not fit, no matter how good the rent is.
Three tests have to pass together: CLTV room, minimum line size and the 1.10x coverage. When one fails, you can shrink the line, wait for the balance to fall, or look at a different structure.
Equity also does not pool. Each line attaches to one property, so equity in one rental cannot fund a line on another.
What Your First Mortgage Must Allow
Check the first mortgage before you apply. The lender needs to know your existing loan allows a junior lien. If the first mortgage is itself a DSCR loan, its documents must allow a junior lien, so read that clause early. Conventional and government-backed first loans each have their own documents, and the note and security instrument are where the answer lives.
If the documents say no, a second lien is off the table with that first loan. Then the choices narrow to replacing the first mortgage or waiting.
There is one more planning point. If you later refinance the first mortgage, the new first lender will want the line to stay behind it. That usually takes the line lender’s cooperation, so factor it in before you open the line.
For borrowers who want broader context, Lendmire’s piece Best Investment Property HELOC Program While Keeping Your Current First Mortgage covers how those programs differ.
Property, 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).
Eligible property: single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots up to 10 acres. The leverage tiers above apply to every property type.
Not eligible on this program:
- Rural-designated property, row homes, condotels and leaseholds.
- Commercial, agricultural or mixed-use property, and hobby farms.
- Land trusts, age-restricted communities, modular and log homes, and land contracts.
- A property listed for sale in the prior 2 months, or one with a solar lien.
A declining-market flag can lower the leverage ceiling. Hazard insurance must cover both liens, with flood coverage where required.
Valuation. Lines up 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 on Form 1004, 1073 or 1025. Appraisal waivers are not accepted.
Title. A full title policy applies on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report.
Who can borrow. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. A borrower can hold at most 5 loans or $2,500,000 with the program.
What You Document, and What You Don’t
The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. You do not provide tax returns, W-2s or pay stubs, and there is no debt-to-income ratio. Your personal income is never calculated.
That does not mean nothing is documented. The rent, the lease, the credit report and the valuation are all documented and reviewed. A typical file includes:
- the current first-mortgage statement,
- an insurance declaration,
- the vesting deed,
- the lease and rent evidence.
One more point on how you use the money. 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.
How Does the Line Work After Closing?
Lendmire’s line has a 5-year interest-only draw period on the drawn balance. Then comes a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable, and the rate and pricing terms come with the lender’s disclosures.
At least 80% of the line is drawn at closing, and that first draw is never less than $50,000. Later draws are at least $5,000 each.
This is the standard open-end structure. The CFPB’s HELOC explainer describes a draw period followed by a repayment period in which you can no longer borrow. The CFPB frames that around owner-occupied homes, so read it as background on the mechanics, not as the rules for a rental line.
On a sale, a HELOC generally has to be paid off in full. The CFPB’s HELOC brochure says so for homes, and the same logic applies to a junior lien on a rental you sell.
Keep the First Mortgage or Replace It?
The reason to choose a second lien is simple. A low first mortgage stays untouched while you borrow only what you need. A cash-out refinance replaces the whole loan, including that low first mortgage.
The honest trade-off is blended cost. A cheap first loan plus a pricier second is a different bet than one new loan on the full balance. Do that math using the actual terms from the lender’s disclosures before you decide.
| Factor | DSCR HELOC | DSCR cash-out refinance | Personal-income bank HELOC |
|---|---|---|---|
| First mortgage | Stays in place | Replaced | Stays in place |
| Reviewed on | Rent | Rent, under that program’s rules | Your income |
| Structure | Revolving line | One new loan | Revolving line |
| Availability | Select programs | Wider | Limited on rentals |
On that last column, NerdWallet notes that a HELOC on an investment property isn’t offered by all lenders, comes with strict qualification requirements, and draws on a smaller pool of lenders than a primary-home HELOC. A bank line also looks at you, not just the property. That matters most if you are self-employed or already carrying a lot of debt.
A short decision sequence helps:
1. Is your first mortgage worth keeping? If yes, lean toward a second lien. 2. Does the first mortgage allow a junior lien? If no, the line is not available behind it. 3. Does rent cover the full limit at 1.10x, and does your score reach 720? If not, resize the line or look at another structure.
When This Isn’t the Right Fit
Several situations send you elsewhere. The point is to find out before you apply.
- No rental. The line is never made on your own home or a second home.
- Recent purchase or refinance. The two six-month clocks above are not met.
- Listed for sale lately. A listing in the prior 2 months blocks the property.
- Score under 720 with a mortgage you keep. A different product, such as a cash-out refinance, is the route.
- Rural, row home or condotel. The property type is outside this program.
- Buying a property. The line is never closed together with a purchase.

Key Terms Defined
DSCR (debt service coverage ratio): the rental’s gross monthly rent divided by the payment the lender tests.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Second lien: a loan recorded behind your first mortgage, which is paid after the first if the property is sold or foreclosed.
Stress payment: the payment the lender uses to test coverage, calculated on the entire credit limit at the starting rate plus 2 percentage points.
Draw period: the stretch when you can borrow from the line. Here it is 5 years, interest-only on the drawn balance.
Seasoning: the waiting period the lender requires after you buy or refinance a property.
Junior lien permission: the right, set out in your first mortgage documents, to put another lien behind the first.
Frequently Asked Questions
Can I get a DSCR HELOC without refinancing my first mortgage?
Yes. The line is written as a standalone second lien behind the first mortgage you keep. Your first loan keeps its balance, term and maturity. Approval is subject to underwriting, the 720 score floor on a second lien, and the first mortgage’s documents allowing a junior lien.
Does the first-mortgage payment count in the rent test?
Confirm on the file how the lender treats the first-mortgage payment. The qualifying payment is principal and interest on the full line at a stress rate, with taxes and insurance left out. The lender’s own coverage calculation on a second lien governs, so ask before you size the line.
How long must I own the rental first?
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).
Can I hold the property in an LLC?
Yes, on investment property, subject to lender program eligibility. The LLC members sign as guarantors, and a title holder who is not a borrower signs the non-borrowing owner acknowledgment and security instrument. The borrowers on the line need not match the borrowers on the first mortgage.
What if my credit score is below 720?
A second lien behind a kept mortgage has no option below 720. A cash-out refinance, which replaces the first mortgage, may be worth a look. Each product has its own score, leverage and coverage rules, subject to lender guidelines.
