The Quick Read: It depends on the smallest of three limits: the equity left after the first mortgage, the program’s dollar cap, and the rent coverage on the whole line, and a full $1,000,000 line is reachable only as a first lien on a rental with no mortgage, at 65% LTV and a 720 score, subject to underwriting. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
- A second lien, which sits behind the first mortgage you keep, tops out at a $500,000 line and 70% CLTV at a 720 score.
- A first lien on a rental with no mortgage runs to $1,000,000, but lines above $500,000 are capped at 65% LTV.
- The rent must cover a stress payment on the entire limit at 1.10x, not only on the part you draw.
- The property is typically worth at least 1.5 times a $1,000,000 line before the leverage cap even allows it.
A DSCR HELOC is a revolving line secured by a rental, qualified on the rent instead of your personal income. The mechanics below come from the programs Lendmire places files with across its wholesale network, and every figure is a ceiling or floor, not an offer.
Key Terms Defined
DSCR: the debt-service coverage ratio, which is gross monthly rent divided by the qualifying payment.
Stress payment: a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, used only to test coverage.
CLTV: combined loan-to-value, which is the first mortgage balance plus the new line, divided by property value.
LTV: loan-to-value on a first lien, where the line is the only debt on the property.
Draw period: the first 5 years, when you pay interest only on the drawn balance, followed by a 25-year repayment period.
Lien position: whether the line sits behind a first mortgage (second lien) or stands alone as the first mortgage (first lien).
How Is the Line Size Set?
The line size is the lowest of three numbers. Equity room is property value times the leverage cap, minus existing liens. The program’s dollar cap is the second limit. Rent coverage on the full line is the third.
Lenders generally set a credit limit as a percentage of appraised value minus what is owed, as the CFPB’s HELOC booklet lays out. That booklet is written for owner-occupied homes, so use it for the arithmetic and structure, not for investor limits. Investor limits come from the program tiers below.
Most borrowers hit one wall first. Heavily mortgaged rentals run out of equity room. High-value, lightly mortgaged rentals run into the dollar cap or the leverage step-down. Rentals with modest rent for their value run out of coverage. Running all three tests before you apply shows which wall is yours.
Where Does the $1,000,000 Ceiling Apply?
Only on a first lien. A second lien stops at $500,000, so a headline of up to $1,000,000 describes a rental with no mortgage on it. Lines start at $50,000 on both structures.
| Factor | Second lien | First lien |
|---|---|---|
| Rental has | A first mortgage you keep | No mortgage |
| Largest line | $500,000 | $1,000,000 |
| Leverage, lines to $500,000 | 70% CLTV at 720+ | 75% LTV at 740+; 70% at 700-739 |
| Leverage, lines above $500,000 | Not offered | 65% LTV at 720+ |
| Credit floor | 720 | 700 |
Two notes on the table. A second lien has no cell below a 720 score. A borrower with a first mortgage and a 700-719 score has no tier on this program, because a first lien exists only on a rental with no mortgage.
A declining-market flag on the property lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower. All figures are subject to underwriting and apply through select programs.
How Much Value Does a $1,000,000 Line Take?
At 65% LTV, the property must be worth about 1.54 times the line. That is the break-even. A property valued below that gets a smaller line, even if everything else is clean.
Put it in ratio terms. If the declining-market flag applies, the cap drops to 60%, and the property then needs roughly 1.67 times the line. These are percentage relationships, so they hold at any price.
Now the second-lien version. The first mortgage and the new line together can reach 70% of value. If the first mortgage already sits at 50% of value, the line can use only the remaining 20% of value. If the first sits at 60%, only 10% of value remains.
Rentals bought with 20% to 25% down start near or above these caps. They usually have little or no second-lien room until the first mortgage balance falls or the value rises. The remaining equity is also all you have to size against. A line cannot exceed the room left after the first mortgage.
First-lien tiers work the same way for the smaller lines. A rental with no mortgage and a 740 score can reach 75% LTV on lines to $500,000. Dropping to a 700-739 score lowers that to 70%. Adding anything above $500,000 moves the whole line to the 65% tier at 720 or better.
How Does the Rent Test Cap the Line?
Rent coverage must reach 1.10x, measured on the full credit limit. The qualifying payment is principal and interest, fully amortizing, on the entire line at the start rate plus 2 percentage points. Taxes and insurance are not part of it.
Because the test uses the whole limit, a larger line needs proportionally more rent. Double the line and the qualifying payment roughly doubles, so rent must double to hold the same coverage. An undrawn balance still counts.
Rent is the lesser of the appraisal’s Form 1007 market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required. A two-to-four-unit property may have at most 1 vacant unit.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. That treatment is not set out in the program summary. It can change how much rent a given line needs, so ask before you size.
This is also where equity and rent separate. A rental can have plenty of equity room and still not support the line, because the stress payment is sized on the entire limit. A smaller line is often the cleaner fit. The qualifying arithmetic here is illustrative, and the lender’s own calculation governs.
What Gets Drawn at Closing?
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. This is not a line you open and leave idle.
On a large line, that is a large drawn balance from the start. You pay interest only on the drawn balance during the 5-year draw period. After that, a 25-year fully amortizing repayment period runs to a 30-year maturity. Later draws are at least $5,000 each.
The rate is variable. The CFPB booklet notes that HELOCs typically carry variable rates and that a lender can freeze or reduce a line if circumstances change. Cash flow can tighten when the rate moves. The rate and pricing terms come with the lender’s disclosures.
Valuation, Title, and Eligibility Gates
The valuation path depends on line size. Lines to $400,000 use an automated valuation with a confidence score of 85 or better and 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 follows the lien. A first lien and a second lien above $400,000 take a full title policy. Smaller second liens use an owner-and-encumbrance report.
Several gates sit outside the math:
- Vesting: the LLC can stay on title, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
- Credit history: no 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Borrowers: U.S. citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
- Exposure: at most 5 loans or $2,500,000 per borrower with the program. One $1,000,000 line uses 40% of the dollar exposure.
- Reserves and cash to close: none required.
- 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).
- Property types: single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots to 10 acres. 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 2 months, and a property with a solar lien are out.
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, and Regulation Z §1026.3 addresses how rental-property credit is classified.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Hazard insurance covers both liens, and flood coverage applies where required.
Choosing the Line Over the Refinance
A DSCR HELOC fits an owner who wants to reach a rental’s equity without touching the first mortgage. A first lien fits a free-and-clear rental where the owner wants a revolving structure.
The short version is that a refinance resets the first mortgage, while a line leaves it in place.
It may not fit if you want a small draw and a large idle line, because the closing draw rule is at least 80% of the line. It may not fit if the first mortgage already sits near the CLTV cap, or if the property type is on the excluded list. Rent that cannot cover the stress payment on the full limit is the other common stopper, and a smaller line may solve it.

Frequently Asked Questions
Can I really get a $1,000,000 DSCR HELOC?
Only as a first lien on a rental with no mortgage, with a score of 720 or better. Lines above $500,000 carry a 65% LTV ceiling, so the property needs a value of about 1.54 times the line. Rent coverage of 1.10x on the full limit and a full interior appraisal also apply, all subject to underwriting.
What is the largest second-lien line?
$500,000, at up to 70% CLTV and a 720 score. The first mortgage balance counts toward that 70%, so a high first mortgage leaves less room. No second-lien tier exists below 720.
Does the rent test use the amount I draw or the whole line?
The whole line. The qualifying payment is fully amortizing principal and interest on the entire limit at the start rate plus 2 percentage points, with a 1.10x minimum. Taxes and insurance are not part of it, and the lender’s own calculation governs.
How long must I own the rental before opening a line?
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). These are program minimums, subject to underwriting.
Can an LLC hold the line?
Yes, the LLC can stay on title for an investment property, subject to program terms. The members sign as guarantors, and the borrowers on the line need not be the borrowers on the first mortgage. The line is never offered on an owner-occupied home or a second home.
