You financed a rental with a DSCR first mortgage, and you want to leave that loan exactly as it is. The equity keeps building, and you would like to reach it without a refinance. This guide walks through what the lender checks, in order.
The Quick Read: A DSCR HELOC (a revolving line of credit on a rental, qualified on the property’s rent instead of your personal income) can sit as a standalone second lien behind the DSCR first mortgage you keep, provided your first loan’s documents allow it, the title is eligible, and combined leverage fits under the program’s cap.
- Behind a first mortgage you keep, the line is a second lien. Through select programs it reaches up to 70% combined loan-to-value (CLTV) on an investment rental at a 720 credit score or better, on lines from $50,000 to $500,000, subject to underwriting.
- The rent qualifies the line at a minimum 1.10x coverage on a stress payment over the whole line. It qualifies primarily on property-level rental income, with no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
- Your first mortgage stays untouched, but its own paperwork decides whether a junior lien is allowed.
- Your LLC can stay on title, subject to program terms. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Key Terms Defined
Second lien: a loan recorded behind your first mortgage. If the property is ever sold or foreclosed, the first lender is paid first.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
DSCR (debt service coverage ratio): the property’s monthly rent divided by the qualifying monthly payment. A higher number means more cushion.
Stress payment: a qualifying payment built on the whole credit limit at a higher test rate. It is used to qualify the line, and it is not the payment you will actually make.
Subordination: a junior lender’s written agreement to stay behind a new first lien. You need it if you refinance the first mortgage later while the line is open.
Closed-end second: a second mortgage funded as a single lump sum, with no revolving access.
What Is a DSCR HELOC, and What Does the Label Hide?
The label is not a standardized product. Across Lendmire’s wholesale network, the same phrase can mean a revolving line, a lump-sum second mortgage, or a cash-out refinance that replaces your first loan. Only the first of those leaves your first mortgage alone and gives you a line you can draw again.
The version discussed here is a standalone second lien on a rental you own. It is never closed together with a purchase, and it is never a third lien. It is not offered on your own home or a second home.
The next table shows how the three structures differ.
| Structure | Your first mortgage | Access to funds |
|---|---|---|
| DSCR HELOC (second lien) | Stays in place | Revolving line, draws after closing |
| Closed-end second | Stays in place | One lump sum |
| DSCR cash-out refinance | Replaced | One lump sum, new first loan |
A bank HELOC that is reviewed around personal income and debt-to-income is a different product with its own rules. A DSCR HELOC reads the rental. Your pay stubs and tax returns are not part of the qualification, subject to lender guidelines and underwriting. For the full background on rent-based investor financing, see the complete DSCR loans guide.
Gate 1: Will Your First Mortgage Allow a Second Lien?
This gate can end the plan, so check it before anything else. Your first lender’s note and security instrument control what you may add to the property. The new lender cannot waive those terms for you.
Pull both documents and look for three things:
- An additional-lien or encumbrance covenant, which restricts other loans recorded against the property.
- Transfer language and a due-on-sale clause, which let the lender demand payoff if certain events happen.
- A prepayment penalty. It stays in force when you add a second lien, so it matters mostly if you later replace the first loan.
Then ask the servicer, in writing, whether a junior lien is permitted. The company collecting your payment may not be the party that decides, so a written answer saves a failed application later.
Federal law helps here, but only partly. The Garn-St Germain statute lists the creation of a subordinate lien among the situations where a lender may not enforce a due-on-sale clause. That protection applies to residential property with fewer than five dwelling units. It does not say whether the protection reaches a business-purpose loan on a rental or an LLC-owned property. It also does not clearly override a separate additional-lien covenant. Have an attorney read your own documents before you rely on it.
Gate 2: Can the Title Carry the Line?
Title is the second gate, and the program is more flexible on it than most bank products. The rental can be vested in your LLC, subject to program terms. The LLC’s members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
The people on the line do not have to be the same people on your first mortgage. That helps when an LLC took title after the first loan closed, or when partners have changed.
Two title situations are outside the program. Land trusts are not eligible, and neither are leaseholds. If your rental sits in either, this line is not available on the property as titled, so talk with your attorney about whether re-titling is appropriate before you apply, or consider a different structure.
The 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 on this program.
Gate 3: How Much Combined Leverage Is Left?
Leverage is simple arithmetic, and your first mortgage uses up the room first. Take the first-mortgage balance, add the new line, and divide by the property’s value. Behind a first mortgage you keep, that CLTV must stay at or under 70% on an investment rental, at a 720 credit score or better, subject to underwriting. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
The CFPB’s HELOC booklet explains that lenders commonly set a credit limit by taking a percentage of appraised value and subtracting what you owe. The same logic applies here, with the ceiling stated as a combined figure. The table below runs the math on first-mortgage balances stated as a share of value.
| First mortgage vs. value | Room under a 70% CLTV cap |
|---|---|
| 50% | 20 points |
| 65% | 5 points |
| 70% | None |
| 75% | None, already over |
Three adjustments can shrink the room further. A declining-market flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower. The line also must be at least $50,000, so a small gap on a modest-value property may not support a line at all.
A purchase DSCR loan written at high leverage often leaves nothing for a second lien until the balance falls or the value rises. Value is set by the lender’s own valuation, so your estimate of the property’s worth does not decide the number.
Does the Rent Still Cover the Line?
The minimum is 1.10x. That figure is gross monthly rent divided by a stress payment: a fully amortizing payment on the entire credit limit, at the start rate plus 2 percentage points. 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 can have at most 1 vacant unit.
Two features of the test surprise people:
- The stress payment covers the full limit, not just the drawn balance. A line you only plan to use partly still has to pass at full size.
- The stress payment is higher than what you will actually pay. Your real payment during the draw period is interest-only on the drawn balance. That is why a file can pass at a slim ratio and still feel tight in the month-to-month budget.
Run the test with two numbers. Rent divided by the stress payment alone should land at 1.10x or above. A property sitting at 1.05x fails. One at 1.20x passes with cushion.
How the lender treats your first-mortgage payment in the second-lien coverage calculation is a point to confirm on the file. The lender’s own calculation governs. For your own planning, also run rent against the stress payment plus your first-mortgage payment. If that second number looks thin, the property may cash-flow poorly after the line is drawn, even if the first number clears.
Several fixes exist when coverage is short. A smaller limit lowers the stress payment, within the $50,000 minimum. Stronger rent supported by receipts can lift qualifying income. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. A lease in place is required either way.
What the Rest of the File Looks Like
Once the three gates and the coverage test clear, the lender reviews a short list. Each item is a program ceiling or floor, not an offer, and all of it is subject to underwriting.
- Credit: a 720 minimum on a second lien. The tier is the lender’s own credit report. There can be no 30-day late on a mortgage in the last 12 months, and 48 months must have passed since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
- Reserves and cash to close: none required.
- Line size and draws: lines start at $50,000. 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 of interest-only payments on the drawn balance. A 25-year repayment period follows, for a 30-year maturity. The rate is variable.
- Valuation: lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Lines above $400,000 require a full interior appraisal. Appraisal waivers are not accepted.
- Title work: a full title policy on second liens above $400,000, and an owner-and-encumbrance report on smaller 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).
- Exposure: at most 5 loans or $2,500,000 per borrower with the program.
- Insurance: hazard insurance covers both liens, with flood coverage where required.
Edge Cases That Change the Answer
The general rule is that a clean first loan, an eligible title, and enough room produce a workable file. These cases bend it.
- Five or more units. The program covers one-to-four-unit rentals only, and the statute’s due-on-sale protection also stops below five units.
- Excluded property types. Rural-designated property, row homes, condotels, mixed-use, commercial or agricultural property, age-restricted communities, and modular or log homes are outside this lane. So is a property with a solar lien, or one listed for sale in the prior 2 months.
- A hard-money or private first lien. These notes often carry tighter lien language than a standard DSCR note, so Gate 1 deserves extra attention.
- A converted residence. A former primary home may still carry owner-occupant terms in its first mortgage. Read the occupancy language before you add a line.
- A first loan with a prepayment penalty. Adding a second lien leaves the first loan, and its penalty, in place. Because you avoid paying that penalty, this is often the whole reason to choose a second lien over replacing the first loan.
- Condominiums. Warrantable and non-warrantable condos are eligible property types, and the same leverage tiers apply.
Keep the First Mortgage or Replace It?
Keeping the first mortgage preserves its existing terms and any prepayment structure. The tradeoff is that a second lien adds a payment on top of the first. As the CFPB explains, a home equity loan and a HELOC are both second mortgages when a first mortgage exists, and a HELOC is a revolving line that usually carries an adjustable rate. Second-lien pricing and the rate terms come with the lender’s HELOC disclosures, so compare them against the cost of replacing the first loan.
| Factor | Keep first, add second lien | Replace with cash-out |
|---|---|---|
| First loan terms | Preserved | Reset |
| Prepayment penalty | Not triggered | May apply |
| Funds access | Revolving line | One lump sum |
| Added monthly cost | Second payment | One new payment |
Credit changes the picture. If you keep a first mortgage, only the second-lien tier applies, and it starts at 720. A 700-719 score does not reach it behind a mortgage you keep. A rental with no mortgage can take a standalone first lien instead. That reaches 75% loan-to-value (LTV) at 740 or better, and 70% at 700 to 739, on lines up to $500,000. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Plan for the exit as well. If you later refinance the first mortgage with the line open, the new first lender will want the second lien paid off or subordinated. The line’s holder must consent in writing and is not obliged to. Without that consent, the line moves up in priority.

If a Gate Fails, What Next?
Each failed gate points to a specific alternative. The table maps them.
| Failed gate | Practical next step |
|---|---|
| First loan bars junior liens | Ask the servicer for written terms, or plan a cash-out |
| Title is a land trust | Re-title if appropriate, or use another structure |
| No CLTV room | Wait for paydown or value growth, or consider a cash-out |
| Coverage under 1.10x | Shrink the limit or document stronger rent |
| Score below 720 | Build credit, or consider a cash-out refinance |
Before You Apply
Collect these items first:
- Your first mortgage note and security instrument, plus the servicer’s written position on a junior lien.
- Your current first-mortgage balance and a realistic view of value, so you can compute CLTV.
- The signed lease, and three months of rent receipts if your lease is above market rent.
- Your title structure, including the names of every member and anyone who holds title but will not be a borrower.
- Your purchase or refinance note date and settlement date, so seasoning is clear.
- A list of your other loans with the program, to stay within the exposure ceiling.
Frequently Asked Questions
Can a DSCR HELOC sit behind a DSCR first mortgage?
Yes, when the first loan’s documents tolerate a second lien, the title is eligible, and combined leverage stays within the cap. Behind a first mortgage you keep, the line is a standalone second lien, up to 70% CLTV at a 720 score or better on an investment rental. The servicer’s written position on your first loan is the step that most often needs attention. Everything is subject to underwriting.
Does my first-mortgage payment count in the coverage test?
Confirm that on the file, because the lender’s own calculation governs. The qualifying payment is built on the entire credit limit at a stress rate, and taxes and insurance are not part of it. For planning, test rent against the stress payment alone and against the stress payment plus your first-mortgage payment. Both views show you how much cushion the property really has.
How soon after buying or refinancing can I apply?
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). Both clocks must be satisfied before the file is eligible.
Can my LLC hold title to the rental?
Yes, 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. Land trusts and leaseholds are not eligible.
Is this available in every state?
No. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Those states are Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia, and Washington.
