The Quick Read: A DSCR HELOC is a revolving line written as a standalone second lien behind the first mortgage the owner keeps, and it is qualified on the rental’s income instead of the owner’s personal income. Through select programs, subject to underwriting, the line tests rent against a stress payment on the whole credit limit. Which lenders fit depends on the file: credit tier, combined leverage, property type, title and the first mortgage’s terms.
- The second lien tops out at 70% combined loan-to-value (CLTV) at a 720 credit score or better, on lines from $50,000 to $500,000.
- Rent must cover the qualifying payment on the full line at 1.10x or better.
- An LLC can stay on title, subject to lender program eligibility.
- Two six-month seasoning clocks apply, and the line is offered in 15 of Lendmire’s 16 licensed states. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Lendmire is a mortgage broker. It does not lend. It places these files with wholesale lenders in its network and matches the scenario to the program.
What Is a DSCR HELOC Behind a First Lien?
A DSCR HELOC is a home equity line of credit on a non-owner-occupied one-to-four-unit rental. It sits in second position behind the first mortgage, which stays in place. The rent qualifies the line. No traditional personal-income documentation, W-2s or pay stubs go in the file, and the owner’s personal income is never calculated, subject to lender guidelines.
Two lien positions exist in this program. The second lien goes behind a mortgage the owner keeps, including an existing DSCR loan. The first lien goes on a rental with no mortgage at all. A borrower who keeps a mortgage can only take the second-lien version. The line is never closed together with a purchase, never a third lien, and never placed on the owner’s own home or a second home.
Do not mix it up with a primary-residence HELOC. That is an owner-occupied product with its own rules, and this line is never offered on an owner-occupied home.
The line is also not a DSCR loan. A DSCR loan is a closed-end first mortgage tested on rent.
How Does Underwriting Treat the Second Lien?
Two separate loans mean two separate underwriting files. The second lender never inherits the first lender’s approval of the existing mortgage and decides on its own file.
Here is the sequence a second-lien file runs through, step by step.
1. Product fit. The line must be a standalone second lien on an eligible one-to-four-unit rental, with a lease in place. A two-to-four-unit property may have at most one vacant unit.
2. Credit tier. A second lien needs a 720 score or better, taken from the lender’s own report. There is no second-lien cell below 720. Mortgage history shows no 30-day late in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
3. Combined leverage. Add the first mortgage balance to the new line and divide by value. That CLTV runs up to 70% on a second lien, subject to underwriting. A declining-market flag lowers the ceiling by 5 points.
4. Rent. Rent is the lesser of the appraisal’s market rent (Form 1007) and the lease, unless three months of receipts support a lease above market.
5. The coverage test. Gross monthly rent divided by the qualifying payment must reach 1.10x. The qualifying payment is a fully amortizing payment on the entire credit limit, at the start rate plus 2 percentage points. That is a stress payment. It covers principal and interest only, not taxes or insurance.
6. Valuation. Lines to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
7. Title and insurance. Second liens above $400,000 get a full title policy. Smaller second liens use an owner-and-encumbrance report. Hazard insurance covers both liens, with flood coverage where required.
The stress payment is the part most investors miss. The test runs on the whole line, not on the amount drawn. A $300,000 line is tested as if fully drawn and fully amortizing. An owner who plans to draw half still has to clear the test on all of it.
The first-mortgage payment is the open question. Whether it joins the qualifying payment on a second lien depends on the lender’s coverage calculation. Confirm on the file how the lender treats the first-mortgage payment, because a thin first-lien coverage ratio can look different once a second is stacked on it. The illustrative arithmetic here is not the lender’s, and the lender’s own calculation governs.
Which Lenders Write These Lines (and How Does a Broker Find the Fit)?
The lender pool is small. NerdWallet’s explainer on investment-property HELOCs says fewer lenders offer them than offer primary-home lines, that borrowing room is smaller and that qualification is strict. Many big banks and large retail lenders stay out of the rental line business or qualify it on personal income and a smaller equity share.
That is why a broker matters. Lendmire works with a network of wholesale DSCR HELOC lenders and matches the file to the program. It does not list or rank lenders, and no single answer fits every file. Which lenders fit depends on the property type, credit profile, combined leverage, title and documentation.
Three product types sit under the “DSCR HELOC” label in the market:
| Product | Who is underwritten | Lien position |
|---|---|---|
| Bank-style investment HELOC | Owner’s personal income and debt | Usually second |
| Closed-end rent-based second | The rental’s income | Second |
| Rent-based revolving line | The rental’s income | First or second |
The DSCR HELOC described here is the third row. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Ask any lender which row its product belongs in before you spend money on a valuation.
What Leverage Does the Program Allow?
Second liens stop at 70% CLTV, at a 720 score or better, on lines up to $500,000. Nothing above 70% exists on a second lien, and no second-lien line runs above $500,000. Those are ceilings, not offers, and each file is underwritten individually.
Run it as a ratio. A rental valued at 100 units with a first mortgage at 50 units of balance has room for a line of up to 20 units at 70% CLTV. The line cannot cross the dollar caps either way, and a flagged declining market lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
A first lien works differently, and it applies only to a rental with no mortgage:
| Lien | Score | Leverage | Line size |
|---|---|---|---|
| First lien | 740+ | 75% LTV | Up to $500,000 |
| First lien | 700–739 | 70% LTV | Up to $500,000 |
| First lien | 720+ | 65% LTV | Above $500,000 to $1,000,000 |
| Second lien | 720+ | 70% CLTV | $50,000 to $500,000 |
An owner with a DSCR first mortgage in place sits in the second-lien row. The first-lien rows matter only when the rental is free and clear. NerdWallet reports that at least 20% equity is a typical market requirement for an investment-property HELOC. That is a market-wide figure, not this program’s. This program’s ceilings are the ones in the table.
How Does the Line Draw, Repay and Mature?
The draw period runs 5 years, interest-only on the drawn balance. A 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
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. This is not a line you open and leave mostly unused. It is a structure for an owner who wants the equity now and the option to draw more.
The CFPB’s HELOC guidance explains that an open-end line lets you borrow repeatedly during the draw period, that repayment follows, and that a lender may stop further draws if the home’s value drops significantly. Variable payments also move with the balance, as the agency’s HELOC booklet lays out. The rate and the pricing terms come with the lender’s disclosures.
Rent stays roughly flat while a variable-rate payment does not. That mismatch is the real risk on a rent-covered line. Interest-only payments during the draw period give way to a larger amortizing payment at the start of repayment. Plan for that step before drawing.
Where Does the General Rule Break?
Most of the friction lives in the edges. These are the ones that derail files.
First-lender consent. The first mortgage’s note and deed of trust must permit a junior lien. If they do not, the second lender will not close. Pull those documents and get the servicer’s position on the junior lien in writing before applying. Do not assume a first lender will not notice or will not care.
Title. Vesting in an LLC is allowed on this program, for investment property only, subject to lender program eligibility. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not match the borrowers on the first mortgage. Bank-style HELOCs often want an individual or a revocable trust on title, which is why LLC-held rentals tend to get stuck there.
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). A recent DSCR first closing starts the first clock. An owner who just refinanced into a DSCR loan has to wait it out.
Property exclusions. Outside this lane: rural-designated property, row homes, condotels, 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 and a property with a solar lien are out too. Warrantable and non-warrantable condominiums are eligible property types, and the leverage tiers above govern every type.
Borrower type. U.S. citizens, permanent residents and non-permanent residents with a Social Security number qualify. Foreign nationals and ITIN borrowers do not.
Exposure. The program allows at most 5 loans or $2,500,000 per borrower. A larger portfolio can hit that limit before it hits any other.
Refinancing the first later. The CFPB says a HELOC can affect your ability to refinance the first mortgage, because the line’s lender may have to agree to subordinate. For a DSCR investor planning a later cash-out, the second lien must be paid off or subordinated. Sequence the two deals before opening either one.
Piggyback seconds. A piggyback second is made at the same time as the main mortgage to avoid mortgage insurance on a low down payment. It is a different thing. This line is never closed together with a purchase.
Key Terms Defined
Second lien: a loan secured by the same property, ranked behind the first mortgage for repayment.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Stress payment: the fully amortizing payment on the whole credit limit at a higher test rate, used only to measure coverage.
Draw period: the years when the borrower can take money from the line and pays interest only on the drawn balance.
Form 1007: the appraiser’s market rent schedule for a rental property.
Subordination: an agreement that lets a new first mortgage rank ahead of an existing line.
HELOC, Closed-End Second or Cash-Out Refinance?
The choice turns on what you are protecting. If the DSCR first mortgage is worth keeping, a second lien taps equity without replacing it. A cash-out replaces the existing mortgage with a new one. The CFPB notes that a cash-out refinance replaces the mortgage and can cost more or less than a HELOC depending on terms.
| Factor | DSCR HELOC (second lien) | DSCR cash-out refinance |
|---|---|---|
| Existing first mortgage | Stays in place | Replaced |
| Payment type | Variable, interest-only draw | Set by the new loan |
| Best fit | Keeping a good first loan | Resetting the whole debt |
Replacing a DSCR first can also trigger its prepayment terms, so read the note first. The honest answer is that this is a close call on some files. A strong first loan favors the line. A thin first-lien coverage ratio or a loan near the end of its useful life favors the refinance.
An equity cushion matters either way. Every dollar of second lien leaves less room if values fall, and a lender can freeze draws in a falling market.
What to Pull Before You Apply
Gather these before the file goes in:
- The first-mortgage statement and the note and deed of trust, for the junior-lien language
- The insurance declaration, showing coverage for both liens
- The vesting deed, so title and any LLC are clear
- The signed lease and, if rent exceeds market, three months of receipts
- The members’ information if the LLC will sign as guarantor
Then ask the servicer in writing about the junior lien. Check that the title matches the vesting deed and that the insurance declaration is current and complete, since gaps in either can be fixed before the file goes in.
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.
Frequently Asked Questions
Can a DSCR HELOC sit behind an existing DSCR first mortgage?
Yes, if the first mortgage’s documents allow a junior lien and the file clears the second lender’s own test. The first loan stays in place. The line is a standalone second lien at up to 70% CLTV with a 720 score or better, subject to underwriting. Get the servicer’s position in writing before applying.
Does the DSCR lender on the first loan have to approve the line?
The first lender does not underwrite the second. What matters is whether the first-lien note and deed of trust permit a junior lien. If they do not, a second lender will not close. Read those clauses and confirm with the servicer.
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). A recent DSCR first closing can start the first clock.
Can an LLC hold title on the rental?
Yes, vesting in the owner’s LLC is allowed on this program for investment property, subject to lender program eligibility. Members sign as guarantors.
