The Quick Read: The maximum on a DSCR second lien is not one number that a single provider owns. It comes from the program’s combined loan-to-value ceiling, the first mortgage you already carry, the program’s dollar cap, and whether the rent covers a stress payment on the whole line. Across the wholesale programs Lendmire works with, a second lien reaches up to 70% combined loan-to-value (CLTV) at a 720 credit score or better, on lines of $50,000 to $500,000, subject to underwriting. The provider that fits you depends on your property, your score and your equity. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
- A DSCR HELOC is a standalone second lien behind the first mortgage you keep, or a first lien on a rental with no mortgage.
- Rent qualifies the line, and your personal income is never calculated.
- Market overlays can lower the ceiling below the program’s headline figure, so the final number depends on the property’s location and market.
- The dollar cap and the percentage cap both apply, and whichever is lower sets your maximum.
- This is a drawn line rather than a mostly unused reserve, because at least 80% of it is funded at closing.
Key Terms Defined
DSCR (debt-service coverage ratio): gross monthly rent divided by the qualifying payment. This program asks for 1.10x or better.
HELOC: a revolving credit line secured by property. You draw, repay, and draw again within the limits of the program.
Second lien: a loan recorded behind your first mortgage. If the property is sold or foreclosed, the first mortgage is paid before the second.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Stress payment: a fully amortizing payment calculated on the entire credit limit, not only on the amount you have drawn. The lender uses it to test coverage.
Draw period: the stretch when you can borrow from the line and pay interest only on the drawn balance.
Seasoning: the waiting period a program requires after you buy or refinance a rental.
What a DSCR HELOC Actually Is
A DSCR HELOC lets you borrow against a rental’s equity without touching the first mortgage. The CFPB’s HELOC explainer describes the basic design: an open-end line you can borrow against repeatedly, with a draw period followed by a repayment period. Its warning about default applies to landlords too. Falling behind can put the property at risk, and for you that property is the rental.
The DSCR version differs from a bank line in who qualifies it. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. There is no traditional personal-income documentation: no W-2s, pay stubs or personal debt-to-income calculation. The rent, the lease, the credit report and the valuation are all documented.
The program is built for non-owner-occupied one-to-four-unit rentals. It never closes together with a purchase and is never a third lien. It is never written on your own home or a second home. If you hold the rental in an LLC, that can stay on title, subject to program terms. The members sign as guarantors.
How Underwriting Sets the Maximum, Step by Step
Think of the maximum as a funnel with four filters. Your line is the smallest result that comes out the bottom.
Step 1: Start with value. The CFPB’s consumer booklet explains the general logic. A credit limit is typically a percentage of the home’s appraised value, less what is owed on the mortgage. A DSCR second lien follows the same logic with a lower percentage.
Step 2: Apply the CLTV ceiling. On a second lien, the combined ceiling is 70% at a 720 score or better. Multiply value by that ceiling, then subtract every lien already on the property. What remains is the most the line can be.
Step 3: Apply the dollar cap. Second-lien lines run from $50,000 to $500,000. A high-value rental with a small first mortgage hits the dollar cap first. A heavily mortgaged rental hits the percentage first.
Step 4: Run the coverage test. Gross monthly rent must be at least 1.10x the qualifying payment. That payment is principal and interest, fully amortizing, on the entire credit limit at a stress rate. Taxes and insurance are not part of it. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market.
Because the test uses the full limit, a bigger line makes coverage harder. A line sized at the CLTV ceiling can still fail on rent. The lender’s own calculation governs the final answer. Confirm on the file how the lender treats your first-mortgage payment, because that detail is not published for second liens.
Worked Examples in Percentages
Here are three illustrative rentals under a 70% CLTV ceiling at 720 or better. The percentages are modeled, not market data, and the lender’s own calculation governs.
| Scenario | First mortgage vs. value | Room under the 70% ceiling |
|---|---|---|
| Ample equity | 30% of value | 40% of value |
| Tight equity | 60% of value | 10% of value |
| No room | 70% of value or more | None |
In the ample-equity case, the dollar cap may stop you before the percentage does. In the tight case, the room may fall below the $50,000 minimum line, and then there is no line to write. In the third case, the CLTV ceiling is already used up by the first mortgage. A refinance or a different structure becomes the conversation.
Why a Top-Providers List Cannot Tell You Your Maximum
Ranked lists are tempting, but the maximum depends on your file. Property type, score, lien position, equity and entity title all move it. A list that puts one name first cannot know any of that.
Lendmire is a mortgage broker, not a lender. It works with a network of wholesale DSCR HELOC lenders and matches a scenario to the program that fits. The best program for your situation is the one whose ceilings, property rules and valuation path line up with your rental. The lenders that write this product vary by state, by property type and by overlay.
It also helps to know what you are comparing against. Market surveys report that bank-style rental HELOCs are harder to get than lines on a primary home, because lenders see higher default risk, and that they commonly want a 720 score. Those bank products lean on personal income. A DSCR second lien in the network also starts at 720, but it is reviewed on rent.
Investors in a BiggerPockets discussion describe calling around because few banks offer rental HELOCs. That fits what a broker sees: the product is specialized, so shopping many programs matters more than picking a famous name.
The Structures and Variations
Second lien versus first lien. If you keep a first mortgage, you can only take a second lien, and the second-lien floor is 720. A first lien exists only on a rental with no mortgage.
A first lien has its own tiers, written as loan-to-value (LTV) because there is no other loan. Its floor is 700, and the tiers are:
- 740 or better: up to 75% LTV on lines up to $500,000.
- 700 to 739: up to 70% LTV on lines up to $500,000.
- Lines above $500,000, up to $1,000,000: 65% LTV at 720 or better. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
A borrower at 700 to 719 who keeps a first mortgage has no second-lien cell, because the second-lien floor is 720.
One tier on a second lien. A higher score does not buy more leverage here. The second lien has a single cell, and nothing above 720 changes it.
Draw rules. At least 80% of the line is drawn at closing, and the 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 interest-only on the drawn balance. Then a 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable, and the lender’s HELOC disclosures carry the pricing terms.
Valuation and title. Lines up to $400,000 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 on Form 1004, 1073 or 1025. Appraisal waivers are not accepted. Title is a full policy on a first lien and on second liens above $400,000, and an owner-and-encumbrance report on smaller second liens.
Closed-end seconds and cash-out refinances. Some products sold as a HELOC are closed-end seconds that pay out one lump sum. A DSCR cash-out refinance replaces the first mortgage instead of sitting behind it.
| Feature | DSCR HELOC (second lien) | Closed-end second | DSCR cash-out refinance | Bank HELOC |
|---|---|---|---|---|
| First mortgage | Stays in place | Stays in place | Replaced | Stays in place |
| Funds | Revolving line | One lump sum | One lump sum | Revolving line |
| Reviewed on | Rent | Varies by program | Rent | Usually personal income |
| Leverage | Up to 70% CLTV | Varies by program | About 75% LTV on standard rentals | Varies by bank |
| LLC title | Allowed, per program terms | Varies by program | Often allowed | Often declined |
The second lien trades leverage for keeping the first mortgage you already have. For a longer look at how those trade-offs compare, Lendmire’s piece Best Investment Property HELOC Program for the Maximum Amount Allowed on a Second Lien covers the sizing decision.
Where the General Rule Breaks
The 70% rule has edges. These are the named ones.
- 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).
- Credit history. There can be no 30-day mortgage late in the last 12 months. The program also wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. Lenders use their own credit report to set the tier.
- Market flags. A declining-market flag lowers the ceiling by 5 points. Some markets carry a ceiling 10 points lower.
- Property types. One-to-four-unit properties qualify, including single-family, PUD, townhome and condominium, and lots up to 10 acres. Rural-designated property, row homes and condotels are outside the program. So are commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts and mixed-use. A property listed for sale in the prior 2 months or carrying a solar lien is also out.
- Occupancy and leases. A lease must be in place. A two-to-four-unit property may have at most one vacant unit.
- Borrower type. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
- Exposure. The program allows at most 5 loans or $2,500,000 per borrower.
- Footprint. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
- Reserves. The program does not require reserves or cash to close.
Every figure here is a ceiling or floor on select programs, subject to underwriting, not an offer.
Three Misconceptions That Cost Investors Time
“A $500,000 maximum means I can borrow $500,000.” The dollar cap is only the top of the funnel. Your existing liens and the CLTV ceiling can each bind first, so test both before you count on the full amount.
“The line is my standby reserve.” On this program, at least 80% is drawn at closing and interest starts on that balance. If you want a large undrawn cushion, this is not that product.
“The line buys my next rental.” It supplies cash from a seasoned rental. It is not purchase financing. The lender on the next purchase must accept borrowed funds, and you should confirm with that lender how it treats this line’s payment in its own coverage calculation.
How to Compare Providers on the Maximum
Whether you work through a broker or on your own, ask each provider the same questions:
1. What is the CLTV ceiling on a second lien, and does my score reach it?
2. What is the dollar cap, and does it change by lien position?
3. Does the coverage test run on the full limit or only the drawn balance?
4. What are the opening draw and minimum later draw?
5. Which valuation applies at my line size, and is the title requirement different?
6. Will my first mortgage documents allow a junior lien?
7. Does the program accept my LLC title, and what is the exposure cap per borrower?
8. Do any market overlays lower the ceiling on my property?
A provider that answers all eight in writing is easier to compare than one that quotes a single headline number. Lendmire’s complete DSCR loans guide covers how coverage ratios and program tiers work if you want the wider picture.
Frequently Asked Questions
Is a DSCR HELOC a second mortgage?
Yes, when you keep a first mortgage, it is recorded behind that loan as a second lien. Both payments stay your responsibility, and the first mortgage is not touched. On a rental with no mortgage, the same line is written as a first lien instead.
What is the most I can borrow on a second lien?
The ceiling is up to 70% CLTV at a 720 score or better, on lines of $50,000 to $500,000, subject to underwriting. Your actual maximum is value times 70%, minus every existing lien, then limited by the dollar cap. The rent must also cover the stress payment on the full line at 1.10x or better.
Can a lower score still get a second lien?
No, there is no second-lien cell below 720. A borrower at 700 to 719 who has a first mortgage has to look at other structures, such as a different program or a cash-out refinance. A borrower with no mortgage can take a first lien at 700.
Does the line count against my next purchase’s coverage ratio?
That depends on how the purchase lender treats borrowed funds and existing debt, so ask that lender before you rely on either answer. Your credit file will show the new line either way.
Why do some banks refuse a rental HELOC?
Banks often treat rental collateral as higher risk and use personal income and title rules that exclude LLCs. Some investors in a separate BiggerPockets thread describe banks declining unless the property is classified as a second home. A DSCR program is built for the rental itself.
