The Quick Read: Usually up to 70% combined loan-to-value on a second lien at a 720 credit score or better, minus your first mortgage balance, capped at $500,000 per line and tested against the rent. The rental’s equity sets the ceiling, and the rent decides whether the full line clears the coverage test, all subject to underwriting.
- A second lien sits behind the first mortgage you keep, so that loan is left alone.
- Line size = value × 70% CLTV, minus the first mortgage balance, up to $500,000.
- Lines start at $50,000, and rent must cover the full line at a stress payment.
- A rental with no mortgage can take a first-lien line, up to 75% LTV at 740 or better on lines up to $500,000, and up to $1,000,000 at a 65% LTV ceiling above $500,000.
- Available in 15 of Lendmire’s 16 licensed states. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
An owner with a first mortgage they like has a clear question: how much equity can the rent unlock without touching that loan? The answer is arithmetic first, then a coverage check. Lendmire arranges these lines as a broker through a wholesale network, and every figure below is a ceiling or floor on select programs, not an offer.
How Is the Line Size Calculated?
The line is value times the maximum combined loan-to-value, minus every lien already on the property. Then the program’s dollar cap applies, and the rent must still cover the payment.
Combined loan-to-value (CLTV) is all loans secured by the property divided by its value. Yahoo Finance’s CLTV explainer walks through the arithmetic and notes that paying down debt or gaining equity lowers the ratio. Wall Street Prep gives the same formula: total secured balance over appraised value.
Here is how it plays out in ratio terms. Take a rental valued at 100 units. A first mortgage at 55 units, under a 70% CLTV ceiling, leaves 15 units for the line. A first mortgage at 70 units or more leaves nothing. This is illustrative, and the lender’s own calculation governs.
| First mortgage vs. value | Room under 70% CLTV | What it means |
|---|---|---|
| About 40% | About 30 points of value | Large line, likely limited by the $500,000 cap or the rent test |
| About 55% | About 15 points of value | Moderate line |
| 70% or more | None | No second-lien line until paydown or appreciation |
Whichever limit is lowest decides the amount: equity, the dollar cap, or rent coverage.
What Are the Second-Lien Limits?
On a second lien, the network ceiling is 70% CLTV at a 720 credit score or better, on lines from $50,000 up to $500,000, through select programs and subject to underwriting. There is no second-lien tier below 720. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Two details matter for sizing. First, the CLTV counts the first mortgage balance plus the new line. Second, a declining-market flag can lower the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
A better credit score does not lift a second lien past 70%. The 720 tier is the only second-lien tier, so extra score buys cushion on the file, not extra leverage.
When Is a First-Lien Line Available?
A first-lien line exists only on a rental with no mortgage. It reaches 75% LTV at 740 or better and 70% LTV from 700 to 739, on lines up to $500,000. Lines above $500,000, to $1,000,000, carry a 65% LTV ceiling at 720 or better. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
If you keep a first mortgage, you can only take a second lien, and that needs a 720 score. A 700-719 borrower with a mortgage in place is not blocked by lien position. The block is the second-lien score floor.
Does the Rent Limit How Much You Can Borrow?
Yes. Rent must produce at least a 1.10x debt service coverage ratio, which is gross monthly rent divided by a qualifying payment. That payment is a fully amortizing principal-and-interest payment on the entire credit limit at a stress rate above the start rate. Taxes and insurance are not part of it.
The key point is that the test runs on the full line, not on what you draw on day one. A $400,000 line you only plan to use half of is still tested as if fully used.
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, and a two-to-four-unit property may have at most one vacant unit.
How the first-mortgage payment enters the coverage math on a second lien is not something the program spells out. Confirm on the file how the lender treats it, because the lender’s calculation governs. That is why a cushion above 1.10x matters. Thin rent can leave a line smaller than the equity alone would allow. If the coverage number is tight, trimming the requested line is usually cleaner than hoping the qualifying payment lands favorably.
The qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines. No traditional personal-income documentation, W-2s, pay stubs or personal debt-to-income ratio are part of the file, though the lease, the credit report and the valuation are.
What Does the Draw Structure Do to Your Capital Plan?
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.
So this is not a standby line you leave mostly untouched. It suits an owner who has a defined use for most of the money now and may want smaller top-ups later.
The draw period is 5 years, interest-only on the drawn balance. Then a 25-year fully amortizing repayment period begins, for a 30-year maturity. The rate is variable.
The CFPB’s HELOC booklet explains the point plainly: with a variable rate, your payment can change even if you borrow nothing more, and the payment steps up when repayment starts. That booklet is written for homeowners, so treat it as a general explanation of how lines behave, not a statement of what applies to a business-purpose line. Stress-test your own cash flow at full draw and at a higher payment before you size up.
Which Properties and Borrowers Are Eligible?
Eligible: single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots up to 10 acres. The LLC can stay on title, subject to lender program eligibility. Members sign as guarantors, and a title holder who is not a borrower signs a non-borrowing owner acknowledgment.
Not eligible on this lane:
- Rural-designated property, row homes and condotels
- Commercial, agricultural or mixed-use property
- Leaseholds, land trusts and age-restricted communities
- Hobby farms, modular and log homes, and land contracts
- A property listed for sale in the prior 2 months
- A property with a solar lien
Borrowers must be US citizens, permanent residents or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. Credit also needs a clean recent record: no 30-day mortgage late in the last 12 months, and 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves or cash to close are required, and exposure is capped at 5 loans or $2,500,000 per borrower with the program.
How Does the Valuation and Seasoning Work?
Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
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).
A recent high-leverage purchase may therefore sit above the ceiling for a while. Paydown or appreciation lowers CLTV over time, and a fresh valuation is what shows the change.
DSCR HELOC or Cash-Out Refinance: Which Fits Your Mortgage?
The first mortgage is the deciding variable. Keep a first loan you like, and a second-lien line leaves it untouched. A cash-out refinance replaces it, which means the whole balance is repriced.
| Your situation | Likely better fit |
|---|---|
| Good first mortgage, staged capital needs | DSCR HELOC (second lien) |
| First mortgage you want to replace | DSCR cash-out refinance |
| One lump sum, permanent capital | Cash-out refinance |
| Rental with no mortgage | First-lien DSCR HELOC |
| Cash need above 70% CLTV room or the $500,000 cap | Cash-out refinance |
The flip point is size. If the amount you need exceeds the line’s equity room or dollar cap, the line cannot stretch to cover it. The complete DSCR loans guide covers how property-rent-based lender review works in general.
Other products in the market work differently. A home equity line qualified on personal income and credit is a separate product with its own rules, and big banks often refuse LLC title on those. This line is built around rent and allows LLC vesting, but that flexibility comes with the stress-payment test on the full limit.
Key Terms Defined
- CLTV: the first mortgage balance plus the new line, divided by the property’s value.
- DSCR: gross monthly rent divided by the qualifying payment.
- Stress payment: a fully amortizing payment on the whole credit limit at a start rate plus 2 percentage points.
- Draw period: the first 5 years, when you pay interest only on what you have drawn.
- Seasoning: the 6-month waiting rules tied to your last note date and your time on title.
Before You Ask for a Number
Gather these so the sizing is real, not guessed:
1. Current first-mortgage statement, to confirm the balance and that its terms permit a second lien
2. Signed lease, and rent receipts if the lease sits above market rent
3. Vesting deed showing how title is held, plus entity documents if an LLC owns it
4. Insurance declaration, with hazard coverage for both liens and flood coverage where required
5. A realistic value estimate, to run CLTV before the valuation does
If the numbers fall short, three options are open: wait for paydown, trim the line, or consider a cash-out refinance.
Frequently Asked Questions
What is the most I can borrow on a DSCR HELOC?
On a second lien, up to $500,000 and up to 70% CLTV at a 720 score or better, whichever is lower after your first mortgage is subtracted. A first-lien line on a rental with no mortgage can reach $1,000,000, with a 65% LTV ceiling above $500,000. All of it is subject to underwriting. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Does a bigger rent mean a bigger line?
Not necessarily. Rent must reach 1.10x on the full line, but equity sets the ceiling first. Strong rent keeps you from being coverage-limited. It does not raise the 70% CLTV cap.
Can I use an LLC?
Yes, on investment property, subject to lender program eligibility. Members sign as guarantors. The borrowers on the line need not be the borrowers on the first mortgage.
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).
Does the line cover my own home?
No. It is written only on non-owner-occupied one-to-four-unit rentals. A primary-residence HELOC is a different, owner-occupied product.
If you are considering a home equity line on a rental property and want to see how the numbers work, Lendmire can help you compare DSCR HELOC options based on the property, the rent, the equity available, credit profile, combined leverage, and your goals. Reach the team at 828-256-2183 or through the quote request page.
Most of the sizing comes down to one subtraction, and whichever number runs out first, equity, dollar cap or rent, is the one that sets your line.
