The Quick Read: It depends on three limits, and the smallest one sets your number: equity (combined loan-to-value up to 70% on a second lien at a 720 score), rent coverage of at least 1.10x on a stress payment for the whole line, and a $500,000 ceiling on second-lien lines. All figures are ceilings through select programs, subject to underwriting.
- A second-lien line behind a mortgage you keep reaches 70% CLTV at a 720 score, on lines of $50,000 to $500,000.
- A first-lien line on a rental with no mortgage reaches 75% LTV at 740 or better, and 70% LTV from 700 to 739, on lines to $500,000. Lines above $500,000 run to $1,000,000 at 65% LTV.
- The line is sized to the rent as well as to the equity.
- The owner’s personal income is never calculated, and the LLC can stay on title. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
A home equity line on a rental is a different tool from a cash-out refinance. It leaves the first mortgage alone. It adds a second lien, or a first lien if the property is paid off. This article explains how the limit is built, where each constraint bites, and what a landlord should ask when comparing lenders. For the broader picture of how investor loans work, see Lendmire’s complete DSCR loans guide.
What Sets the Limit When You Borrow on a DSCR HELOC?
Equity sets the first limit. Rent coverage sets the second. The program’s line-size ceiling sets the third. Whichever is smallest wins, and landlords often assume equity is the only gate.
The equity limit. Lenders take a percentage of the property’s value and subtract what is already recorded against it. Home equity is value minus what you owe, and the credit limit is usually a share of appraised value less the mortgage balance, as the CFPB’s HELOC booklet explains. On a rental, combined loan-to-value (CLTV) is the first mortgage balance plus the new line, divided by value. The ceiling on a second lien is 70% CLTV at a 720 score.
The coverage limit. The rent has to cover the line. The minimum is 1.10x, which means gross monthly rent divided by the qualifying payment. The qualifying payment is a fully amortizing principal-and-interest payment on the entire credit limit, stressed above the start rate. Taxes and insurance are not part of it. The test runs on the full limit, not on what you plan to draw.
The ceiling. Second-lien lines run from $50,000 to $500,000. A first lien can go to $1,000,000, but the leverage drops once the line passes $500,000.
Credit is a gate, not a lever. On a second lien, 720 is the floor and the only tier. Above that score the program does not add leverage.
The Formula, Step by Step
The formula is value times the allowed CLTV, minus every lien already recorded, then capped at the program ceiling. Coverage then tests whether the rent supports that line. If it does not, the line shrinks until it does.
1. Establish value. Lines up to $400,000 use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted.
2. Apply the CLTV or LTV tier. A second lien is capped at 70% CLTV. A first lien is capped at 75% or 70% LTV, depending on score, and 65% above $500,000.
3. Subtract existing liens. On a second lien, the first mortgage balance comes out of the allowed combined amount.
4. Cap at the program ceiling. The ceiling is $500,000 on a second lien and $1,000,000 on a first lien.
5. Run the coverage test on the full limit. 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. On a two-to-four-unit property, at most one unit can be vacant.
6. Apply the screens. Credit tier, mortgage history, property type, seasoning and exposure caps all run alongside the math.
Confirm on the file how the lender treats the first-mortgage payment in the coverage calculation on a second lien. The lender’s own calculation governs.
Worked Scenarios (Percentages and Ratios Only)
These are modeled assumptions, not market data. They show which limit binds. The lender’s calculation governs every real file.
A mortgaged rental. Say the first mortgage sits at 45% of value and the owner has a 735 score. The program allows 70% CLTV, so the line has room for about 25% of value, before the $500,000 ceiling and the coverage test. If the score were 710, no second-lien option exists. The owner would look at a different structure.
A paid-off rental. Picture a rental with no mortgage and a 745 score. A first-lien line can reach 75% LTV on lines up to $500,000. At a 705 score the same line tops out at 70% LTV. If the owner wants a line above $500,000, leverage falls to 65% LTV at 720 or better, and lines run to $1,000,000. On a high-value free-and-clear rental, the dollar ceiling can bind before the percentage does. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
A recent purchase. Consider a rental bought with a purchase loan at 75% of value. It already sits above a 70% CLTV ceiling. No line is possible until paydown or a higher appraised value brings the combined figure under the cap. Seasoning would block it anyway, as covered below.
A line that fails coverage at full size. Run the numbers on a rental where rent covers the full-line stress payment at about 1.0x. That misses the 1.10x minimum. The stress payment scales with the size of the line, so a line roughly 9% to 10% smaller lands near 1.10x. Equity may allow more. Rent says no. A line that fails at full size and passes at a smaller size is a normal outcome of the formula. Qualification stays subject to lender guidelines, credit approval and property review.
The test runs on the whole limit because at least 80% of the line is drawn at closing. 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.
How Is This Different From a Bank Rental HELOC?
A DSCR HELOC is qualified on the rental’s income: no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines. Market surveys report that rental HELOCs are not offered by every lender, and that debt-to-income of 40% to 50% is typical, per NerdWallet. On a DSCR HELOC through this network, the rent coverage test replaces the debt-to-income calculation.
| Factor | DSCR HELOC | DSCR cash-out refinance | Bank rental HELOC |
|---|---|---|---|
| Existing first mortgage | Stays in place | Replaced | Stays in place |
| Reviewed on | Rent coverage | Rent coverage | Personal income and DTI |
| Structure | Revolving line | One new loan | Varies by lender |
| Max leverage | 70% CLTV (2nd lien) | 75% LTV on a standard rental cash-out | Set by that lender |
| LLC on title | Allowed | Per program terms | Often individual title |
A closed-end second mortgage is a third option. It pays out as one lump sum instead of a line you draw on. Which structure fits depends on whether the landlord wants to keep a low-balance first mortgage in place, wants revolving access, or needs more leverage than the line allows.
A primary-residence HELOC is a different, owner-occupied product. This line is never offered on an owner-occupied home.
What Lowers Your Number
Several screens cut the figure before the formula finishes.
- Thin equity. A first mortgage that already consumes most of 70% CLTV leaves little or nothing.
- Low rent. Because coverage is tested on the full limit, weak rent shrinks the line even when equity is plentiful.
- Declining-market flag. A flag lowers the ceiling by 5 points. Philadelphia lines carry a ceiling 10 points lower.
- 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 caps. The program allows at most 5 loans or $2,500,000 per borrower.
- Credit history. There can be no 30-day mortgage late in the last 12 months. Forty-eight months must pass after a bankruptcy, foreclosure, short sale or deed-in-lieu.
A comparison point on credit: tradeline-depth rules are waived at 700 and above, and every tier the program offers meets that score. No reserves and no cash to close are required.
Property and Borrower Fit
Eligible property is single-family, PUD, townhome, two-to-four units, and warrantable or non-warrantable condominiums, plus lots to 10 acres. The leverage tiers above govern every property type.
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 2 months, and a property with a solar lien.
Borrowers can be US citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
For title, the owner’s LLC can hold the property on an investment rental. 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 do not have to be the borrowers on the first mortgage.
Choosing a Lender: Who Writes This and What to Ask
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. Lendmire is a mortgage broker. It works with a network of wholesale DSCR HELOC lenders and matches the property, rent and equity to the program that fits. It does not lend.
The lenders that write rental lines depend on the borrower’s situation: property type, credit profile, leverage need and documentation. Banks and credit unions often underwrite on personal income. Specialty lenders and wholesale lenders may underwrite on rent. A broker shops more than one program.
A few lines separate real programs from a rate-sheet comparison. Ask for these in writing:
- The qualifying payment worksheet. It should show that the payment is on the full limit, with taxes and insurance excluded.
- The structure. Confirm whether it is a revolving line or a closed-end second, since the same label covers both.
- How the first-mortgage payment is treated in the coverage calculation on a second lien.
- The draw rules. These include the share drawn at closing and the minimum later draw.
- LLC vesting. Ask whether the entity can stay on title.
- The valuation path for your line size, and whether an interior appraisal is required.
- Exposure limits per borrower, in loans and in dollars.
- The disclosure package. The rate and the pricing terms come with the lender’s disclosures, not from a headline number.
The terms of the line itself are fixed by the program. Across the network, the draw period is 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. After the draw period ends, borrowing stops and repayment begins, which is how the CFPB describes a HELOC’s life cycle. The same page warns that the home is at risk if the line cannot be repaid.
Key Terms Defined
DSCR (debt service coverage ratio): the rental’s gross monthly rent divided by the qualifying payment. The minimum here is 1.10x.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value.
Lien position: whether the line sits behind a first mortgage (second lien) or stands first on a paid-off rental.
Draw period: the stretch when you can borrow against the line. Here it is 5 years, interest-only on the drawn balance.
Qualifying payment: a fully amortizing payment on the whole limit at a stressed rate, used only for the coverage test.
Seasoning: the time the owner has held the property or loan before the line is available.
Frequently Asked Questions
What is the most you can borrow on a DSCR HELOC?
On a second lien, the most is $500,000, and combined loan-to-value cannot exceed 70% at a 720 score. On a first lien, lines run to $1,000,000. Leverage is 75% LTV at 740 or better and 70% from 700 to 739 on lines to $500,000, and 65% LTV on lines above that. Rent coverage of 1.10x on the full line can lower the figure, and every number is subject to underwriting. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Can my LLC hold title on the line?
Yes, on an investment rental, subject to program terms. The members sign as guarantors. The borrowers on the line need not match the borrowers on the first mortgage.
How long must I own the rental before I can open 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).
What if the full line fails the coverage test?
The line gets resized. A smaller limit lowers the qualifying payment and can bring coverage to 1.10x or above. Equity does not offset weak rent in this test.
Can I use this line on a rural property or a condotel?
No. Rural-designated property, condotels, row homes, leaseholds and several other property types are outside the program. Single-family, PUD, townhome, two-to-four units and condominiums are eligible.
