The Quick Read: The best program for you is a standalone second-lien line, qualified on the rental’s income, that sits behind the first mortgage you keep. Which one fits depends on your credit score, your combined leverage, and how the property is titled. Across the wholesale network Lendmire works with, the programs that write this product share a common shape, and the details below show how it works.
- A second-lien line typically reaches up to 70% combined loan-to-value (the first mortgage balance plus the new line, divided by value), at a 720 credit score or better, on lines from $50,000 to $500,000, subject to underwriting.
- Qualification runs primarily on the property’s rent covering a stress payment on the entire line, with a minimum coverage of 1.10x. It does not require traditional personal-income documentation, W-2s, or a personal income calculation, subject to lender guidelines.
- The LLC can stay on title, and your first mortgage stays untouched.
- Valuation is an automated valuation with an inspection report on lines to $400,000, or a full interior appraisal.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Many investors hold a rental with a first mortgage they never want to give up. Refinancing means repricing the whole balance. A second lien lets you reach the equity and leave the old loan alone. Lendmire is a mortgage broker, not a lender. It places these lines with wholesale lenders and matches the scenario to the program, and the right match changes with each file. Lendmire’s complete DSCR loans guide covers the wider family of rent-qualified loans.
What Is a DSCR HELOC?
A DSCR HELOC is a revolving line of credit on a non-owner-occupied one-to-four-unit rental. The rent qualifies the line instead of your personal income. It is written either as a standalone second lien behind the first mortgage you keep, or as a standalone first lien on a rental with no mortgage.
The term is a market label, not a standardized product. One lender may use it for a revolving line, while another uses it for a lump-sum second mortgage. Always ask which structure is on offer. This article uses it for the revolving version.
A few boundaries apply to every file:
- 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.
Why Keep the First Mortgage?
Keeping the first mortgage preserves its terms. Only the new money is priced at today’s second-lien pricing, while the legacy first stays as it is. A cash-out refinance reprices the entire balance, including the part that was fine.
The Urban Institute describes the same logic: a second lien lets a borrower tap equity while preserving the low rate on the first mortgage. That logic holds for investors too, and many use a second lien to fund the next acquisition without disturbing the loan on the rental they already own.
There is a flip point. If the first mortgage has weak terms, a second lien leaves that problem in place, and a cash-out refinance may serve better. If your first mortgage is no better than what is available now, the keep-the-first advantage is small. Run both paths before choosing.
How Is a DSCR HELOC Underwritten, Step by Step?
Underwriting follows five steps: pick the structure, measure equity room, run the coverage test, review the collateral, and close as a standalone second.
Step 1: Pick the structure. A revolving line suits staged needs, such as a renovation paid in phases. A lump-sum second suits a single fixed need. A cash-out refinance replaces the first mortgage. Each has a different payment profile, and the choice shapes everything after it.
Step 2: Measure equity room. Combined loan-to-value is the first mortgage balance plus the new line, divided by the property value. On a second lien, the ceiling is typically 70% CLTV, subject to underwriting. Subtract your first balance from 70% of the value, and what remains is the most the line could be. A rental already financed near that cap has little or no room.
Step 3: Run the coverage test. The minimum is 1.10x. That means gross monthly rent divided by a qualifying payment, which is a fully amortizing payment on the entire credit limit at a stressed start rate, not on the amount you draw. Rent is the lesser of the appraiser’s market rent from the Form 1007 rent schedule or the lease. A lease above market can count with three months of receipts showing the higher rent. A lease in place is required, and a two-to-four-unit property may have at most one vacant unit.
One detail matters here. Whether the first-mortgage payment joins the qualifying payment on a second lien is not published, so no one outside the lender’s own calculation can give you a formula. Ask which payments the lender counts before you compare programs. Any worked example is illustrative, and the lender’s calculation governs.
Step 4: Review the collateral. The lender looks at your credit report, the lease, the valuation, title, and hazard insurance covering both liens. Lines 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 take 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.
Step 5: Close as a standalone second. The second lien records behind the first. The documents on your first mortgage must allow a junior lien, so read them before you apply.
The Tiers: What Credit and Leverage Look Like
Second-lien leverage is simpler than first-lien leverage because there is one tier. First-lien leverage steps down as the score drops and as the line grows.
| Lien position | Credit score | Maximum leverage | Line size |
|---|---|---|---|
| Second lien (behind your first) | 720 or better | 70% CLTV | $50,000–$500,000 |
| First lien (no existing mortgage) | 740 or better | 75% LTV | Up to $500,000 |
| First lien | 700–739 | 70% LTV | Up to $500,000 |
| First lien, larger line | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
All figures are through select programs, subject to underwriting. Below 720 there is no second-lien option. If your score is 700 to 719, you can still use the line, but only as a first lien on a rental with no mortgage, and that does not help if you want to keep an existing first.
Credit history matters too. There can be no 30-day mortgage late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves and no cash to close are required. A borrower can hold at most 5 loans or $2,500,000 with the program.
How Do the Draw Rules Work?
The draw rules are fixed by the program. A line has a 5-year interest-only draw period on the drawn balance, then a 25-year fully amortizing repayment period, for a 30-year maturity. The rate is variable.
At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each. This differs from a bank-style line where you might draw nothing at first. Here, most of the line is in use from day one, so plan for the payment on the larger balance.
The CFPB notes that home equity lines usually carry variable rates. Its consumer brochure adds that payments can change even if you draw nothing more. That brochure is aimed at consumers generally, not rent-qualified investor lines, but the payment-reset point applies. When the draw period ends, the payment steps up as principal begins. Stress-test your coverage for that step before you apply, not after.
Seasoning, Property Types, and Edge Cases
A property listed for sale in the prior 2 months is ineligible.
Eligible properties include single-family homes, PUDs, townhomes, two-to-four-unit properties, warrantable and non-warrantable condominiums, and lots to 10 acres. The following are outside the program:
- Rural-designated property
- Row homes
- Condotels
- Leaseholds
- Land trusts
- Age-restricted communities
- Mixed-use, commercial, and agricultural property
- Properties with a solar lien
A declining-market flag lowers the ceiling, and Philadelphia lines carry a lower ceiling as well. Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Title and LLC. Many bank home equity lines on rentals want individual title. This program allows vesting in your LLC, which is investment property only, subject to program terms. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line do not have to be the borrowers on the first mortgage.
Practitioner pattern. A common stall is not the score or the rent. It is the combined-leverage math. An investor who bought several years ago and has paid the first down modestly often finds less room than expected, because the 70% ceiling counts the first balance in full. Running that subtraction before anything else saves a wasted application.
DSCR HELOC vs. Other Ways to Reach Equity
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance | Bank HELOC on personal income |
|---|---|---|---|
| Existing first mortgage | Stays in place | Replaced | Stays in place |
| Reviewed on | Rental income | Rental income | Personal income and debts |
| Payout | Revolving line | Lump sum | Revolving line |
| LLC title | Allowed, subject to program terms | Varies by program | Often individual title only |
| Best fit | Keep a good first, tap equity | Weak first, or large cash need | Salaried borrower with low debt |
Bank HELOC rules are that product’s own, and they vary widely by institution. Second liens usually cap lower than a first-lien cash-out, so a very large cash need may push you toward a refinance.
What Decides the “Best” Program for Your Situation?
The best program for your situation comes down to six variables. Use them as a checklist when a broker shows you options.
1. Lien position. Do you need a second behind your first, or do you have a free-and-clear rental?
2. Coverage method. Does the lender’s review run the payment on the whole line or only the drawn amount, and are other payments counted?
3. Leverage room. After the first balance, how much CLTV is left at your credit tier?
4. Draw rules. What must be drawn at closing, and what is the minimum later draw?
5. Payment step-up. What happens at the end of the draw period?
6. Title and property fit. Is your LLC, condo, or lot size within the program?
A broker adds value here because guidelines differ from lender to lender. Some programs write second liens on more property types, and others have stricter overlays. The lenders that write this product depend on your file, so one program that fits another investor may not fit you.
When This Is the Wrong Move
Skip the second lien if any of these apply:
- Your score is below 720 and you have a first mortgage to keep. There is no second-lien cell.
- Your first mortgage documents bar a junior lien.
- Your property is rural, a condotel, a row home, or a leasehold.
- Your rent, after the lesser-of test, does not clear 1.10x on the stress payment for the full line. A smaller line can help, since the test runs on the credit limit.
- You need a very large amount of cash. The second-lien cap of $500,000 and 70% CLTV may be too tight.
Honestly, the last case is a genuine toss-up. A refinance reprices the whole balance, but it can reach more cash. Compare the blended cost of both paths, not just the new money.
Key Terms Defined
Combined loan-to-value (CLTV): The first mortgage balance plus the new line, divided by the property’s value.
Debt service coverage ratio (DSCR): Gross monthly rent divided by the qualifying payment; it shows whether rent covers the debt.
Second lien: A loan recorded behind the first mortgage, so the first lender is paid first if the property is sold.
Draw period: The stretch when you can borrow against the line, here 5 years interest-only on the drawn balance.
Stress payment: A fully amortizing payment on the entire credit limit, used only to test coverage.
Form 1007: The appraiser’s rent schedule that sets market rent.
Frequently Asked Questions
Can I keep my first mortgage and still get a DSCR HELOC on the same rental?
Yes, on a second-lien structure. The line records behind your first mortgage, which stays in place, subject to underwriting. Your first mortgage documents must allow a junior lien, so confirm that first. Leverage is counted on a combined basis, so the first balance reduces how much line is available.
Do I need tax returns or pay stubs?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lender still reviews your credit report, the lease, the valuation, and title. There is no personal income or debt-to-income calculation.
Can my LLC hold the property?
Yes, subject to program terms. The property must be investment property.
What credit score do I need to keep my first mortgage and add a line?
A 720 score or better is the second-lien minimum, and there is no second-lien option below that. A first-lien line, for a rental with no mortgage, starts at 700. Both are through select programs and subject to underwriting.
How soon after buying can I open a line?
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).
