The Quick Read: It depends on the equity left after your first mortgage: through select programs, a second-lien line goes up to 70% combined loan-to-value at a 720 credit score or better, in amounts from $50,000 to $500,000, and rent must cover the whole line at 1.10x, subject to underwriting. The smaller of the equity ceiling and the dollar cap sets the maximum. Rent coverage then decides whether the line is usable at that size. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
- Second lien (you keep the first mortgage): up to 70% CLTV at 720 or better, lines to $500,000.
- First lien (rental with no mortgage): up to 75% LTV at 740 or better, 70% LTV at 700 to 739, on lines to $500,000.
- Larger first-lien lines: above $500,000 and up to $1,000,000, the ceiling is 65% LTV at 720 or better.
- Rent test: gross monthly rent of at least 1.10x a stressed, fully amortizing payment on the entire credit limit.
- Footprint: offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
How Do You Size the Line in Three Steps?
The maximum line is the lesser of three numbers: the equity room, the program’s dollar cap, and the size the rent test supports. Equity room is property value times the allowed ceiling, minus every lien already recorded. The dollar cap is $500,000 on most structures. The rent test then checks whether the line size works.
1. Pick the lien position. A borrower who keeps a first mortgage can only take a standalone second lien. A first lien exists only on a rental with no mortgage at all.
2. Apply the ceiling and subtract the liens. On a second lien, the ceiling is combined loan-to-value (CLTV). That is the first mortgage balance plus the new line, divided by the property’s value. Yahoo Finance’s CLTV explainer walks through the same formula. The full line amount counts toward the ratio, not only what you draw.
3. Check the dollar bounds and the rent. The line must be at least $50,000 and no more than the cap for that structure. Rent coverage on the full limit is the last gate.
This product is never offered on an owner-occupied home or a second home, since owner-occupied lines are a different product. Programs change, and every file is underwritten individually.

What Does the Equity Math Look Like on a Second Lien?
The first mortgage balance, as a share of value, sets the room. At the 70% CLTV ceiling, every point of value already pledged to the first mortgage comes straight out of the line.
| First mortgage (% of value) | Room for the line at 70% CLTV | Room if declining-market flag applies |
|---|---|---|
| 40% | 30% of value | 25% of value |
| 50% | 20% of value | 15% of value |
| 55% | 15% of value | 10% of value |
| 65% | 5% of value | None |
| 70% or more | None | None |
The declining-market flag lowers the ceiling by 5 points, so the right-hand column uses a 65% CLTV. Those percentages are illustrative ceilings, not offers. The valuation, credit tier and lender review decide the final figure.
The $50,000 minimum matters at the bottom of the table. On most properties, 5% of value falls short of that floor, so the room exists on paper but no line fits in it.
A paid-off rental, first lien
Say you own a rental free and clear and your score is 740 or better. The first-lien ceiling is 75% LTV on lines up to $500,000, so the line is 75% of value or $500,000, whichever is smaller. At 700 to 739 the same line drops to 70% LTV. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
A line above $500,000 is sized at 65% LTV at 720 or better, and it runs to $1,000,000. That has a catch. A larger line only helps when 65% of the value clears $500,000. On a property near that threshold, the 75% tier capped at $500,000 can beat the 65% tier.
A mid-balance rental, second lien
Consider an investor with a 730 score and a first mortgage at 55% of value. The 70% CLTV ceiling leaves room for a line worth up to 15% of value. If the property is valued high enough, that room clears the $50,000 floor. If it is not, the line does not exist at any price.
Then comes the rent test. The qualifying payment is figured on the entire credit limit, so a line sized at the full 15% room needs more rent than a smaller line. If rent covers the full line at around 1.0x, the line has to shrink by roughly 9% to reach 1.10x. Coverage moves in inverse proportion to line size.
A tight-equity rental
A borrower with a first mortgage at 66% of value has 4% of value left at 70% CLTV. In most cases that falls under the $50,000 minimum. If the declining-market flag applies, the room is gone altogether. This borrower’s realistic options are paying the first mortgage down, waiting for value to rise, or looking at a cash-out refinance instead.
How Does the Rent Test Cap the Line?
The rent test caps the line when rent covers the payment on the full limit at less than 1.10x. The qualifying payment is principal and interest, fully amortizing, on the entire credit limit at a stressed rate. Taxes and insurance are not part of it. An undrawn balance still counts against you.
This is where the product differs from a standard HELOC. The rent qualifies the line, so no traditional personal-income documentation, W-2s or personal income calculation are needed, subject to lender guidelines. The loan is reviewed primarily on property-level rental income covering the payment.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The appraiser’s market rent comes from a rent schedule. Fannie Mae’s appraiser forms page names the two standard forms, Form 1007 for one-unit properties and Form 1025 for two to four units. That is a form-name reference only, because these lines are not agency products. A lease must be in place, and a two-to-four-unit property can have at most one vacant unit.
One point to confirm on any second-lien file: how the lender treats the first mortgage payment in the coverage calculation. That treatment can change the result, so ask for the lender’s worksheet. The lender’s own calculation governs.
What Shrinks Your Number?
Credit. The minimum is 720 on a second lien and 700 on a first lien, using the lender’s own credit report. Mortgage history needs no 30-day late in the last 12 months. A bankruptcy, foreclosure, short sale or deed-in-lieu needs 48 months behind it.
Valuation. Lines to $400,000 use either an automated valuation with a confidence score of 85 or better plus a property inspection report, or a full interior appraisal. Lines above $400,000 need a full interior appraisal. Appraisal waivers are not accepted. Title runs on a full policy for a first lien and for second liens above $400,000. Smaller second liens use an owner-and-encumbrance report.
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). The line is never closed together with a purchase.
Property. Single-family, PUD, townhome, two-to-four-unit, warrantable and non-warrantable condominiums, and lots to 10 acres are eligible. These are outside the program:
- 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 property
- a property listed for sale in the prior 2 months
- a property with a solar lien
Borrower. U.S. citizens, permanent residents and non-permanent residents with a Social Security number can apply. Foreign nationals and ITIN borrowers cannot. Exposure is limited to 5 loans or $2,500,000 per borrower with the program.
Title. The owner’s LLC can stay on title, subject to lender program eligibility. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment. For how this plays out in practice, see Lendmire’s piece on HELOC rules for LLC-titled borrowers.
Key Terms Defined
CLTV (combined loan-to-value): every loan secured by the property, including the new line, divided by the property’s value.
Lien position: the order in which loans are paid from the property. A second lien sits behind the first mortgage.
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment.
Qualifying payment: a stressed, fully amortizing payment on the whole credit limit, used only for the rent test.
Draw period: the stretch when you can borrow from the line. Here it is 5 years, interest-only on the drawn balance.
How Does This Compare With a Cash-Out or a Personal-Income HELOC?
The three routes differ in what they replace, what they qualify on and how title can be held. Each is described here under its own rules, not the program above.
| Factor | DSCR HELOC | HELOC on personal income | DSCR cash-out refinance |
|---|---|---|---|
| Reviewed on | Rental income | Borrower’s credit and debts | Rental income |
| First mortgage | Stays in place | Stays in place | Replaced |
| LLC on title | Allowed, subject to program | Often an obstacle | Generally allowed |
| Best use | Reach equity, keep first | Owner with strong personal file | Large proceeds, full reset |
A cash-out refinance replaces the first mortgage and is the usual route when you need proceeds above the $500,000 line cap. A line leaves a low-balance or favorable first mortgage untouched.
A bank HELOC on a rental depends heavily on the institution. A personal-income line puts your debt-to-income ratio at the center. Property-rent-based lender review is aimed at investors in that spot.
What Happens After You Draw?
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.
The draw period is 5 years interest-only on the drawn balance. A 25-year fully amortizing repayment period follows, and the maturity is 30 years. The rate is variable.
A CFPB explainer on HELOCs describes the product as an open-end line you can borrow against repeatedly, with variable rates as the usual setup. Pricing terms come with the lender’s HELOC disclosures. Two risks follow from the structure. A variable rate means your carrying cost can move. And when the repayment period begins, the payment steps up because principal is added. Run your rent against that stepped-up payment before you draw.
When Is a Line Not Enough?
A line is not enough when the room is below $50,000, when rent fails the 1.10x test even at a reduced size, or when you need more than $500,000 against a rental. The rental also has to be one you already own. A DSCR HELOC is secured by an existing rental, so a first-time investor’s first move is usually a purchase loan, then a line after seasoning.
Practical checks before you apply:
- Total up every lien on the property, including any other second lien.
- Estimate the room using the table above, and subtract 5 points if the area may be flagged as declining.
- Test rent against the line size you want, then at a smaller size.
- Confirm title: individual, trust or LLC, and whether the property is on the excluded list.
- Confirm the valuation path, since lines above $400,000 need a full interior appraisal.

Frequently Asked Questions
What is the most I can borrow on a second-lien DSCR HELOC?
The ceiling is 70% CLTV at a 720 score or better, on lines of $50,000 to $500,000. The actual amount is that ceiling times value, minus the first mortgage, capped at $500,000. Rent coverage on the whole limit can bring it lower, subject to underwriting.
How soon after buying or refinancing can I 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). The line is never closed with a purchase.
Does an unused portion of the line count against the rent test?
Yes. The qualifying payment is figured on the entire credit limit, so unused credit still counts. Asking for a smaller line can bring coverage up to 1.10x where the maximum would fail.
Can I hold the rental in an LLC?
Yes, vesting in the owner’s LLC is allowed on this investment-property line, subject to lender program eligibility. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument. Borrowers on the line need not be the borrowers on the first mortgage.
What if my score is between 700 and 719 and I have a first mortgage?
Then the second-lien floor of 720 is the obstacle. A first lien at 700 or above exists only on a rental with no mortgage. Lifting the score or paying off the first mortgage changes which lane you fit, subject to lender guidelines.
