The Quick Read: A revolving line secured by a rental you keep, written behind your existing first mortgage or alone on a paid-off property, is qualified on the rent rather than your personal income, with minimum coverage of 1.10x tested on the entire credit limit instead of the drawn balance. A closed-end second pays one lump sum instead. The line suits staged capital needs, and the lump sum suits a single known cost. Everything below is subject to underwriting and lender guidelines.
- The line is a standalone second lien behind the first mortgage you keep, or a standalone first lien on a rental with no mortgage.
- The rent qualifies it: no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
- Second-lien leverage tops out at 70% combined loan-to-value (CLTV), and first-lien leverage tops out at 75% loan-to-value (LTV).
- The coverage test runs on the whole limit, and at least 80% of the line is drawn at closing, so the limit you pick is close to the balance you carry.
- Seasoning and ownership clocks, property-type exclusions and the valuation path decide more files than the coverage number does.
Is This a Standard Product?
No. “DSCR HELOC” is a market label, not a fixed product with one rulebook. One lender’s line is revolving and another’s is a lump-sum second. A third is a business line of credit that renews on its own schedule. Quotes use the names interchangeably.
For that reason, structure comes first. The network behind Lendmire (a broker, not a lender) places the line described here: a revolving home equity line on a non-owner-occupied one-to-four-unit rental. It is available through select programs in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. It is never closed together with a purchase. It is never a third lien. It is never written on your own home or a second home.
Availability is thin across the wider market. NerdWallet notes that home equity loans on investment properties are lump-sum products that aren’t widely available and may cost more than loans on primary homes. A rent-qualified revolving line is narrower still. That scarcity is the main reason investors end up comparing it with a closed-end second.
Key Terms Defined
DSCR (debt service coverage ratio): Gross monthly rent divided by the qualifying payment. This program wants at least 1.10x.
Second lien: A loan recorded behind the first mortgage. The first mortgage stays in place.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
Draw period: The stretch when you can borrow against the line. Here it is interest-only on the drawn balance.
Closed-end second: A home equity loan paid out as one lump sum, with no further borrowing after closing.
Qualifying payment: The stressed payment the lender uses to test coverage. It is not the payment you will necessarily make.
What Does the Requirements File Look Like?
The requirements split by lien position. Most are ceilings and floors, not offers, and all are subject to underwriting.
| Requirement | Second lien | First lien |
|---|---|---|
| Leverage | Up to 70% CLTV | Up to 75% LTV |
| Credit floor | 720 | 700 |
| Line size | $50,000 to $500,000 | $50,000 to $1,000,000 |
| Top tier | 720+: 70% CLTV | 740+: 75% LTV |
| Mid tiers | None below 720 | 700-739: 70% LTV |
| Lines over $500,000 | Not available | 65% LTV at 720+ |
A few rules sit outside the table:
- Rent and lease. A lease in place is required. A two-to-four-unit property may have at most one vacant unit.
- Credit history. No 30-day mortgage late in the last 12 months. Forty-eight months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Reserves. None required, and no cash to close.
- Exposure. At most 5 loans or $2,500,000 per borrower with the program.
- Borrowers. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
- Vesting. An LLC can hold title (investment property only), per lender program requirements. The members sign as guarantors. A title holder who isn’t a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line don’t have to match the borrowers on the first mortgage.
Programs change, and every file is underwritten individually.
How Does the Coverage Test Work on a Whole Line?
The test uses the entire credit limit, not only the drawn balance. It is the part most investors miss. Coverage is gross monthly rent divided by a fully amortizing payment on the whole limit at the start rate plus 2 percentage points. That is a stress payment. The program minimum is 1.10x.
Rent is the lesser of two figures: the appraiser’s Form 1007 market rent, or the lease. If the lease runs above market, it counts only with three months of receipts.
Run the logic without dollars. Picture a rental whose rent clears the test comfortably at one line size. Double the limit and the stressed payment roughly doubles with it. Coverage can drop below 1.10x. Because at least 80% of the line is drawn at closing, you can’t size big and leave most of it idle to soften the picture. The limit is the number that gets tested, and most of it becomes your balance on day one. A smaller line is often the cleaner file.
On a second lien, how the first mortgage payment enters the calculation is not published. The lender’s own coverage calculation governs. Don’t assume it is in or out. Ask for the calculation before you pick a line size.
How Does Combined Leverage Set the Maximum Line?
On a second lien, the ceiling is a combined loan-to-value (CLTV) limit that applies to the first mortgage and the line together, and it depends on the borrower’s credit score and the property being an investment property. Subtract the first mortgage balance, as a share of value, from that ceiling. What remains is the largest line.
Say the first mortgage sits at 45% of the property’s value. The line can reach up to 25% of value. If the first mortgage sits at 60%, there is room for 10% of value, and the line may fall under the $50,000 minimum on a modest property. That kills the file. Not ideal.
A declining-market flag lowers the ceiling by five percentage points. Run that case before you commit.
On a paid-off rental the first-lien math is simpler. LTV tops out at 75% for a 740 score or better on lines to $500,000. Above $500,000, the ceiling is 65% LTV at 720 or better. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
For context, market surveys report that lenders on investment-property lines generally want at least 20% equity, per NerdWallet. On this network’s second lien, the 70% CLTV cap leaves 30% of value untouched.
Line or Closed-End Second? (The “Instead Of” Decision)
Pick by how you will use the money. The structures behave differently.
| Factor | Revolving line | Closed-end second |
|---|---|---|
| Funds | Most at closing, later draws | One lump sum |
| Interest accrues | On drawn balance | On full amount |
| Rate type | Variable | Usually fixed |
| Coverage test | Whole limit, stressed | Lender-specific |
| Best use | Staged rehab, next down payment | One known cost |
| Biggest risk | Payment steps up at repayment | Paying on funds not yet needed |
This program’s mechanics are specific. The draw period is 5 years of interest-only payments on the drawn balance. A 25-year fully amortizing repayment period follows, inside 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.
Read that last rule twice. This is not a pure standby line you leave untouched. Most of it is drawn on day one.
Use this decision order:
1. If you have one known cost and want payment certainty, a closed-end second fits better.
2. If you need most of the money at closing and the rest in stages, the line fits.
3. If the existing first mortgage is expensive and you want to replace it anyway, compare a DSCR cash-out refinance instead.
4. If the first mortgage is worth keeping, a second lien in either form leaves it untouched.
Thinking it through: the line looks more flexible, but the draw rules cut that flexibility down. On a file where nearly all the money is needed up front, the closed-end second can be the better pick. That is a genuine toss-up on many files.
Where Do These Files Fail?
Coverage on the full limit. The most common miss. A line sized to the maximum leverage often fails the 1.10x test on the stressed payment. Cut the limit and rerun it.
Seasoning and ownership. Two separate clocks apply. A rental bought or refinanced inside the last 6 months is not eligible, with the clock running from the last note date to the new note date. Separately, 6 months on title are required, running from settlement date to note date. A recent purchase has to wait. The line is never closed with the purchase.
Property type. Eligible: single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots to 10 acres. Not eligible on 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, mixed-use, a property listed for sale in the prior two months, or a property with a solar lien.
Valuation. For lines up to $400,000, the file takes an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Above $400,000, a full interior appraisal is required (Form 1004, 1073 or 1025). Appraisal waivers are not accepted. If a value comes in light, an appraisal reconsideration with recent in-neighborhood sales is the normal first step.
Title and insurance. A full title policy is required on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report. Hazard insurance must cover both liens, with flood coverage where required. A stale or incomplete insurance quote is a classic reason a file pends.
The first mortgage’s documents. The first mortgage stays in place, and its terms still apply to a junior lien. Pull the note and mortgage early.
Business purpose. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
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.
What Happens at the End of the Draw Period?
The payment steps up. After five interest-only years, the balance starts amortizing over 25 years. The federal banking agencies flagged this exact risk in OCC Bulletin 2014-29. Borrowers can struggle when payments rise at the end of draw, whatever the contract.
Variable rates add a second layer. The CFPB’s HELOC booklet explains that on a variable-rate plan, monthly payments can change even if the borrower draws no more money. Plan the exit before closing: repay from a sale, refinance, or hold on rent that still covers the amortizing payment.
Budget for that jump on day one. Rental income that barely covers the interest-only payment will feel tight later.
Which Product Is the Quote Actually Offering?
Because labels collide, ask each lender these questions:
1. Is the line revolving, or funded as a lump sum at closing?
2. Is the qualifying payment based on the full limit or the drawn balance?
3. Is the rate fixed or variable? (The rate and the pricing terms come with the lender’s disclosures.)
4. Can the LLC stay on title?
5. What are the seasoning and ownership rules?
6. How much of the line must be drawn at closing?
What Does the File Need?
A typical file moves in this order:
1. Confirm the property type is eligible and the seasoning and ownership clocks have run.
2. Collect the first mortgage statement, the lease, and the hazard insurance declarations.
3. Add entity documents and guarantor details if an LLC holds title.
4. Order the valuation path that fits the line size.
5. Clear title and reconcile it against the first mortgage payoff or balance.
6. Review the lender’s coverage calculation before signing.
Credit is the lender’s own report. Rent drives qualification. Credit, equity, valuation and property type all still get checked.
Frequently Asked Questions
Can I get a revolving line instead of a closed-end second?
Yes, in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, through select programs in the network. It is a standalone second lien behind your first mortgage, or a first lien on a free-and-clear rental. Outside those states, a closed-end second may be the only rent-qualified option.
Do I need tax returns or W-2s?
No. The rental’s income qualifies the line, subject to lender guidelines. The lease, the credit report, the valuation and the title work are all documented.
Does a second lien change my first mortgage?
The first mortgage stays in place with its own terms. The new line sits behind it. The first mortgage balance counts toward the 70% CLTV ceiling.
Does it work on a property I’m buying?
Not at closing. The line is never closed with a purchase. A rental needs 6 months on title, and one bought or refinanced in the last 6 months is not eligible. A recent purchase has to season first.
Does an LLC work?
Yes, for investment property, per lender program requirements. The members sign as guarantors. A title holder who isn’t a borrower signs the non-borrowing owner acknowledgment and the security instrument.
