The Quick Read: A DSCR HELOC is a standalone line of credit, placed behind the first mortgage you keep, that qualifies primarily on the rental’s income covering the payment, subject to lender guidelines. Your first lender does not have to provide it. This article names no single best provider, because which lender fits your file depends on your property, credit and equity.
- The first mortgage stays untouched, and a different wholesale lender can write the line behind it.
- On a second lien, combined leverage reaches up to 70% of value at a 720 credit score or better, subject to underwriting.
- The rent qualifies the line, with no W-2s, tax returns or personal income calculation.
- Lendmire is a broker, so it matches your file to a program instead of ranking lenders.
What Is a DSCR HELOC Behind a First Mortgage?
It is a revolving line of credit secured by a rental you already own. It sits in second position behind the first mortgage you keep. The two loans are separate, so the first lender and the line lender can be different companies.
DSCR stands for debt service coverage ratio. It measures whether the property’s monthly rent covers the monthly payment. The lender looks at the rental, not at your paycheck.
Lendmire’s complete DSCR loans guide covers the wider family of rent-qualified loans.
The line applies to non-owner-occupied one-to-four-unit rentals. Vesting in your LLC is allowed on investment property, subject to program terms, and the LLC’s members sign as guarantors.
Why There Is No Ranked List of Providers
You will not find a ranked list of lenders here. Lendmire is a mortgage broker. It works with a network of wholesale DSCR HELOC lenders and matches a scenario to the program that fits. Naming a winner would ignore the things that actually decide the outcome.
What changes the answer is the property type, your credit tier, how much equity is left after the first mortgage, and how much of the line you want. The lenders that write this product depend on those facts.
The more useful question is which type of provider will even look at a rental line. The market sorts into three groups.
| Provider type | Rental line likelihood | How it qualifies |
|---|---|---|
| Big banks | Low | Personal income (DTI) |
| Community banks, credit unions | Varies by institution | Often personal income |
| Wholesale lenders via a broker | Higher | Rent-based |
Investment-property lines are a thin market. As one BiggerPockets thread shows, some credit unions and regional banks still offer them, and a rent-based second is the usual pivot when they do not.
A broker shops several wholesale programs at once. That is the practical edge: you compare guidelines side by side instead of applying to one lender at a time.
How Underwriting Treats It, Step by Step
The figures below are ceilings or floors on select programs, and every one is subject to underwriting.
Step 1: Confirm the property is eligible. Eligible types include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. Several property kinds fall outside the program, among them rural-designated property, row homes, condotels, leaseholds, age-restricted communities, modular and log homes, hobby farms, and a property listed for sale in the prior 2 months.
Step 2: Check the clocks. 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).
Step 3: Size the equity. Combined loan-to-value (CLTV) adds the first mortgage balance and the new line, then divides by the property’s value. On a second lien, CLTV reaches up to 70% at a 720 score or better. Lines run from $50,000 to $500,000. Every lien on the property counts toward the total.
Step 4: Run the coverage test. The minimum is 1.10x. That is gross monthly rent divided by a qualifying payment. The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit at a stressed rate, two percentage points above the start 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. A lease must be in place. A two-to-four-unit property may have at most one vacant unit.
The lender’s own calculation governs, and any arithmetic you run yourself is illustrative. Confirm on the file how the lender treats the first-mortgage payment.
Step 5: Credit and borrower checks. A second lien needs a 720 score. The program looks for no 30-day mortgage late in the last 12 months. It wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. No reserves and no cash to close are required.
Step 6: Valuation and title. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines use a full interior appraisal. Appraisal waivers are not accepted.
Because the rent qualifies the line instead of personal income, the file skips traditional personal-income documentation and pay stubs, but it is still fully documented. Rent, lease, credit, valuation and title each require support.
A Worked Example in Percentages
Run the numbers on a rental where the first mortgage sits at 50% of the property’s value. The CLTV ceiling is 70%. That leaves about 20 points of value for the new line, which is real room. The next question is whether that room clears the $50,000 minimum line on your property’s value, and whether rent covers the stressed payment.
Now say the first mortgage already sits at 68% of value. Only about 2 points of room remain, which is too thin for a line starting at $50,000 on almost any property. The equity ceiling decides this, not the rent.
Coverage works the same way. If rent runs about 1.25x the qualifying payment on the full line, the file clears the 1.10x floor. If rent runs about 1.05x, the borrower can request a smaller line, since the test runs on the whole credit limit.
Does the First Lender Have to Approve?
Read your first mortgage documents before you apply. The note and security instrument may contain language about additional liens on the property. The title review for the new line will show the first mortgage, and the wholesale lender expects it to stay in place.
Whether the first lender’s name or loan type changes anything depends on the loan documents and the program. A first mortgage held by a bank and one held by a DSCR lender both sit in first position. The new lender cares about the balance, the payment history, and the combined leverage.
Do not assume the first lender is a gatekeeper, and do not assume it is irrelevant. Pull the documents and check.
Keep, Replace, or Add?
The line leaves your first mortgage untouched. A DSCR cash-out refinance replaces it.
| Option | First mortgage | How you access funds |
|---|---|---|
| DSCR HELOC | Stays in place | Draw, repay, draw again |
| Closed-end second | Stays in place | One lump sum |
| DSCR cash-out refinance | Replaced | One new loan |
A closed-end second is a second lien that funds as a single lump sum. A line works differently. Under the CFPB’s HELOC explanation, a HELOC is an open-end line you can borrow against repeatedly, and you can lose the property if you cannot keep up with payments.
Here are the draw rules on this program:
- At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000.
- Later draws are at least $5,000 each.
- The draw period is 5 years, interest-only on the drawn balance.
- A 25-year fully amortizing repayment period follows, inside a 30-year maturity.
- The rate is variable.
Where the General Rule Breaks
Another line is already on the rental. This program is never a third lien. An existing second or an unreleased line would have to be paid off first.
The first mortgage is already near the cap. If the first mortgage uses most of the 70% CLTV, there is no second-lien room. A declining-market flag on the property lowers the ceiling by 5 points.
Your score sits below 720. Keeping a first mortgage means a second lien, and a second lien needs a 720 score. The first-lien tiers apply only to a rental with no mortgage.
The rental is paid off. Then the line can be a standalone first lien. Leverage reaches 75% LTV at 740 or better, and 70% LTV from 700 to 739, on lines up to $500,000. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling.
You want to buy with it. This line cannot be secured by the property you are buying. It can be drawn later to fund a down payment or reserves on another deal. The purchase lender may apply its own rules to borrowed funds.
The rental is short-term. The program requires a lease in place, so a property run only on short-term stays with no lease does not fit this lane. Short-term rental rules also vary by city, county, HOA and property type. If the property is let on short stays, confirm on the file whether a lease can be put in place before relying on projected rent.
It is your own home. This line is never offered on an owner-occupied home or a second home. A primary-residence HELOC is a different product, and its terms may restrict renting the home out.
You are already near the program’s exposure limit. The cap is 5 loans or $2,500,000 per borrower with the program.
How to Compare Providers
Skip the ranking mindset and use a checklist. A broker can run each item across several wholesale programs.
1. Lien position. Does the program write a standalone second behind your existing first?
2. Review basis. Does it qualify on the rental’s income instead of your personal income?
3. Leverage and tier. What combined leverage does your credit score unlock?
4. Valuation path. Does your line size use the automated valuation or require a full appraisal?
5. Entity title. Can the line sit in your LLC, with members as guarantors?
6. Draw rules. What are the closing draw, the minimum later draw, and the repayment structure?
7. Property exclusions. Does your property type or location fall outside the program?
8. Disclosures. The rate and the pricing terms come with the lender’s disclosures, so read them before you commit.
Gather these documents before you apply:
- the current lease
- a payoff or mortgage statement for the first lien
- entity and title paperwork
- credit authorization for each borrower or guarantor
- proof of hazard insurance, plus flood coverage where required
The hazard insurance policy must protect the property under both liens, so ask your insurance agent to confirm that both lienholders are listed on the policy.
Who It Fits and Who It Doesn’t
It fits a landlord with a low-balance first mortgage worth keeping, meaningful equity, a lease in place, and a credit score of 720 or better. It also fits an owner who prefers not to open the personal income file. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
It fits poorly when the first mortgage already uses most of the allowed leverage. It also fits poorly when the rent barely covers the stressed payment on the full line, and when the property sits outside the eligible types.
Consider that a variable payment stacks on top of your first mortgage, and the payment obligation grows once the repayment period begins. The honest comparison is often between this line and a cash-out refinance that replaces the first mortgage, and the right answer depends on how good your first mortgage is.

Key Terms Defined
DSCR: the debt service coverage ratio, meaning gross monthly rent divided by the qualifying payment.
Second lien: a loan recorded behind the first mortgage, paid second 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.
HELOC: a home equity line of credit, a revolving line secured by property equity.
Closed-end second: a second lien funded as one lump sum with no revolving draws.
Stress payment: the payment the lender calculates at a higher test rate to see whether the rent still covers it.
Frequently Asked Questions
Does my first mortgage lender have to be the one that gives me the line?
No. The line is a standalone product, so a different wholesale lender can write it behind your first mortgage. The first mortgage stays untouched, and the new lender checks the balance, payment history and combined leverage.
How does seasoning work on this line?
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).
Are tax returns or W-2s required?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, equity, the lease, the valuation and title are all still reviewed.
Can my LLC hold title?
Yes, on investment property, subject to program terms. The LLC’s members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment. The borrowers on the line need not be the borrowers on the first mortgage.
What if I have a 700 score and a first mortgage?
A second lien needs a 720 score through this program. A first lien starts at 700, but it exists only on a rental with no mortgage. The path for you may be improving the score, or looking at a cash-out refinance instead.
