The Quick Read: The best fit depends on your lien position, credit score, equity, and how the rental is titled. A DSCR HELOC is a revolving line of credit placed as a standalone second lien behind the first mortgage you keep. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
- A DSCR HELOC sits behind your existing first mortgage and leaves that loan untouched.
- Through select programs, a second lien reaches 70% combined loan-to-value at a 720 score or better, on lines from $50,000 to $500,000.
- The rent has to cover a stress payment on the whole line at a minimum 1.10x.
- At least 80% of the line is drawn at closing, so this is not a standby reserve.
- The lenders that write this are few, and a broker that shops several can match the file to the program.
Investors keep asking for a “top providers” list. The lenders writing this product are a small group, and which one fits depends on facts in your file. This page explains how the product works, what the underwriting looks at, and how to choose.
What Is a DSCR HELOC Behind a First Mortgage?
A DSCR HELOC is a revolving line of credit secured by a rental you keep. It is written as a standalone second lien behind your first mortgage. On a rental with no mortgage, it is a standalone first lien. It is never a third lien. It is never closed together with a purchase. It is never a line on your own home or a second home.
Your first mortgage stays exactly as it is. You are not refinancing it. You are adding a separate loan on top of it.
The rent qualifies the line: no traditional personal-income documentation, W-2s, pay stubs, or personal income calculation, subject to lender guidelines. The rental’s income has to cover the payment. Your LLC can stay on title, depending on program guidelines. The members sign as guarantors, and the borrowers on the line need not be the borrowers on the first mortgage.

Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment. Residential investor programs use rent against the payment, not the net-operating-income formula used in commercial lending.
HELOC: A home equity line of credit. It is an open-end line you can borrow against repeatedly, with a draw period followed by a repayment period, as the CFPB’s explanation of HELOCs describes.
Second lien: A loan that sits behind the first mortgage. If the property is sold or foreclosed, the first lien is paid first.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value. A first lien uses plain LTV, which counts only the new line.
Stress payment: A fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It exists only to test coverage. It is not what you pay.
Seasoning: The waiting period a lender wants after you buy or refinance a property before it will lend against it.
How Does Underwriting Treat It, Step by Step?
Underwriting runs in a set order. Each step can stop the file, so it helps to know them before you shop.
Step 1: Lien position. The lender confirms whether you are asking for a second lien behind a mortgage or a first lien on a free-and-clear rental. A borrower who keeps a first mortgage can only take a second lien.
Step 2: The equity test. Lenders take a percentage of the property’s value and subtract what is already owed. The CFPB’s HELOC booklet describes the same logic. In this program, a second lien reaches up to 70% CLTV at a 720 score or better, subject to underwriting. Below 720 there is no second-lien option.
Step 3: The coverage test. Rent has to clear a minimum 1.10x against the stress payment, which is principal and interest on the full credit limit. Taxes and insurance are not part of that qualifying payment. 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.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. That is the point where the “behind a first mortgage” structure matters most, and the lender’s own calculation governs.
Step 4: Valuation and title. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted. Title work scales with lien position and line size.
Step 5: Closing and draw. 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. Later draws are at least $5,000 each.
Which Rentals and Borrowers Fit?
Eligible property includes single-family homes, PUDs, townhomes, two-to-four-unit buildings, and warrantable and non-warrantable condos, plus lots up to 10 acres. Leverage tiers apply the same way across those types.
Several property types are outside this program: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, and mixed-use. Also excluded are a property listed for sale in the prior two months and a property with a solar lien.
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.
Credit history matters beyond the score. The program looks for no 30-day mortgage late in the last 12 months. It also wants 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves and no cash to close are required. Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
What Are the Draw and Repayment Terms?
The line has a 5-year interest-only draw period on the drawn balance. A 25-year fully amortizing repayment period follows, with a 30-year maturity. The rate is variable. The rate and pricing terms come with the lender’s disclosures.
That variable rate is real payment risk. The CFPB warns that falling behind on a line secured by property could cost you that property. On a rental that is carrying a first mortgage and a second lien, you want to know your combined obligation before you draw.

Provider Types, Not Rankings
Here is how the market is structured.
| Provider type | Typical focus | What to expect |
|---|---|---|
| Bank or credit union | Personal income and DTI | Rent often counted in part |
| Non-bank wholesale lender | Property-rent-based lender review | Reached through a broker |
| Mortgage broker | Shops several lenders | Matches file to program |
NerdWallet reports that lines on investment property are possible, but the lender pool is smaller and borrowing limits are lower than on a primary home. It ties that to lenders seeing higher default risk on rentals. That matches what a broker sees: the lenders that write a rent-qualified line behind a first mortgage depend on the property, the credit profile, and the leverage you need.
Lendmire works with a network of wholesale DSCR HELOC lenders. It is not the lender, and the lender reviews and approves the file. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, under its consumer licensing.
Can Your First Lender Block a Second Lien?
It can complicate one. A second lender is lending behind your existing note, so the terms of that first mortgage matter. Some first mortgages restrict additional liens. Some servicers will only answer questions in writing.
The practical steps:
1. Pull your first mortgage note and deed of trust and read the lien and transfer covenants.
2. Ask the servicer in writing whether a second lien on the property is permitted.
3. Tell your broker who holds the first mortgage, since some lenders review that.
No published rule governs how a DSCR first lien and a separate second lender interact, so treat this as a file-by-file check. Settle it before you spend on a valuation.
DSCR HELOC, Closed-End Second, or Cash-Out Refinance?
Some products sold as a “HELOC” are really closed-end seconds that pay out one fixed amount. The CFPB separates the two: a HELOC is revolving and usually adjustable, while a home equity loan is a lump sum. Ask which one you are being offered.
| Factor | DSCR HELOC | Closed-end second | Cash-out refinance |
|---|---|---|---|
| First mortgage | Stays in place | Stays in place | Replaced |
| Payout | Revolving line | One lump sum | One lump sum |
| Lien position | Second or first | Second | New first |
| Payment structure | Interest-only draw, then amortizing | Fixed amount | New first-lien terms |
A cash-out refinance replaces your first mortgage, so you give up the terms you have. A second-lien line keeps them. That matters if your first mortgage was set up on terms you would not get today. If you refinance the property later, the second lien has to be paid off or cleared first.
Stacking a second lien also uses up equity. Check the combined math before you borrow twice against the same property.
A Worked Example: Equity Room and Coverage
Run the numbers on a rental worth $500,000 with a first mortgage balance equal to 50% of value. At the 70% CLTV ceiling for a second lien at a 720 score or better, the room left is about 20% of value. The line cannot exceed that cushion, and the program’s $50,000 minimum line has to fit inside it.
Now the coverage test. Say rent clears the qualifying payment on the whole line at roughly 1.2x. That is above the 1.10x minimum. Because the test runs on the full credit limit, a larger line raises the qualifying payment even if you draw less later. In practice, that means line size and rent have to be sized together. This is illustrative arithmetic. The lender’s own calculation governs.
Here is where this goes sideways: thin equity. A property with a large first mortgage may leave too little room for the minimum line.
Where the General Rule Breaks
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).
LLC versus personal vesting. A DSCR HELOC can be written in your LLC, subject to program terms. A personal-income investment HELOC from a bank is a different product with different title rules. Keep the two separate when comparing offers.
Declining markets. A declining-market flag lowers the leverage ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
Owner-occupancy. This line is never offered on an owner-occupied home. Disclose occupancy accurately.
Funding a purchase. The line cannot fund a purchase directly, because it is never closed together with a purchase. It has to be in place before you sign a purchase contract on the next property. The cash can then go toward a down payment if the purchase lender accepts borrowed funds.
How to Choose a Provider
Use this checklist instead of a leaderboard.
- Lien position: Do you have a mortgage, or is the rental free and clear?
- Credit tier: A second lien needs 720 or better. A first lien starts at 700.
- Combined leverage: Does the equity room clear the minimum line?
- First note: Does your existing mortgage allow a second lien?
- Title: Personal name or LLC, and who signs?
- Product type: Revolving line or closed-end second?
- Draw rules: Can you live with at least 80% drawn at closing?
The best program for your situation is the one that clears every line above. A broker that shops multiple wholesale lenders can test the file against each program’s overlays.
What to Gather Before You Apply
- The current lease and, if rent exceeds market, three months of receipts
- First mortgage statement and note details
- Entity documents if the property is in an LLC
- Hazard insurance covering both liens, with flood coverage where required
- Proof of the purchase or refinance date, to check seasoning
Common Mistakes and Risks
Expecting a standby reserve is the first one. Another is assuming rent qualifies every HELOC on a rental. Many bank lines count rent only in part or lean on debt-to-income.
Stacked payments are a third. You carry the first mortgage and the variable-rate line together. 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.
Programs change, and every file is underwritten individually. Figures here are ceilings and floors through select programs, not offers.
Frequently Asked Questions
Can a DSCR HELOC sit behind any DSCR first mortgage?
Not automatically. The first mortgage’s terms, and sometimes the servicer, affect whether a second lien is workable. Read the note, ask for the servicer’s answer in writing, and give your broker the first lender’s details up front.
What credit score do I need?
A second lien behind your first mortgage needs 720 or better, subject to underwriting. A first lien on a rental with no mortgage starts at 700. Below 720 with a first mortgage in place, there is no second-lien option in this program.
How much can I borrow?
A second lien reaches up to 70% CLTV on lines from $50,000 to $500,000. A first lien reaches 75% LTV at 740 or better, or 70% from 700 to 739, on lines to $500,000. First-lien lines above $500,000 run to $1,000,000 at a 65% ceiling at 720 or better. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
How does seasoning work?
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 my LLC hold title?
Yes, subject to lender program eligibility. The members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
