The Quick Read: It depends on how much of the rental’s value your first mortgage already uses: on a second lien, the first mortgage plus the new line can reach up to 70% combined loan-to-value on a rental, at a 720 credit score or better, with lines from $50,000 to $500,000, subject to underwriting. The line is sized from the rent and the equity, not your paycheck. A rental with no mortgage can take a first-lien line with higher ceilings. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
- The formula: value × 70% combined loan-to-value, minus your first mortgage, capped at $500,000 on a second lien.
- The credit gate: 720 or better on a second lien. Below that, the second-lien tier does not exist.
- The coverage test: rent must cover a stress payment on the entire line, at 1.10x or better.
- The catch: at least 80% of the line is drawn at closing, so size it to what you will actually use.
How Is the Maximum Line Calculated?
The maximum line equals the property value times the maximum combined leverage, minus every lien already on the property, then held to the program’s line limits. Combined loan-to-value (CLTV) simply means the first mortgage balance plus the new line, divided by the property’s value.
On a second lien, the ceiling across our wholesale network’s DSCR HELOC program is 70% CLTV at a 720 score or better. The line itself runs from $50,000 to $500,000. The full credit limit counts toward the math, not just the amount you draw on day one.
Here is how it plays out at different first-mortgage balances, written as shares of value so you can drop in your own number.
| First mortgage (% of value) | Room for a second-lien line (% of value) |
|---|---|
| 40% | Up to 30% |
| 50% | Up to 20% |
| 55% | Up to 15% |
| 60% | Up to 10% |
| 70% or more | None |
Two limits sit on top of this table. First, the room has to be big enough to fill the $50,000 minimum line. A 10% slice of a modest-value rental may fall short of that. Second, a declining-market flag on the property lowers the ceiling by 5 points, and Philadelphia lines carry a ceiling 10 points lower.
So the question is never just “what percentage can I get.” It is “what is left after my first mortgage, and is it at least the minimum line?” These figures are ceilings, never offers. Every file is underwritten individually.
Why Do Banks Say No to Second Position?
Banks say no because a second lien sits behind the first mortgage and gets paid second if something goes wrong. On a rental, many depository lenders simply do not want that risk. NerdWallet notes that fewer lenders offer a HELOC on an investment property, you can’t borrow as much as against a primary home, and the requirements are strict.
For you, that means a refusal from a big bank says little about your property. It says something about that lender’s appetite. Wholesale DSCR HELOC lenders write second liens on rentals as a core product, and a broker shops that group instead of hoping one bank’s policy fits.
Many investors also run into a second problem. The bank wants personal income, debt-to-income math and tax returns on a loan secured by a property that pays for itself. A DSCR line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal income is never calculated.
What Credit Score Do You Need, and Does a Higher Score Add Leverage?
You need a 720 score or better for a second-lien line, and a higher score does not buy more second-lien leverage. The lender’s own credit report sets the tier. At 720 and above, the second-lien ceiling is the same 70% CLTV.
Below 720, there is no second-lien cell on this program. The real picture is narrower: if you keep a first mortgage, the line has to be a second lien, and that tier starts at 720. If you improve your score or look at other structures, the picture can change.
Mortgage history matters too. The program looks for no 30-day mortgage late in the last 12 months. It also wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required, subject to underwriting.
How Does a First-Lien Line Differ?
A first-lien line exists only on a rental with no mortgage. If you keep any mortgage on the property, your line is a second lien. There is no middle category.
On a mortgage-free rental, the first-lien ceilings run higher:
| Credit score | Line size | Maximum LTV (first lien, no mortgage) |
|---|---|---|
| 740 or better | Up to $500,000 | 75% |
| 700 to 739 | Up to $500,000 | 70% |
| 720 or better | $500,000 to $1,000,000 | 65% |
Notice the last row. Larger lines get a lower ceiling, not a higher one. An owner who wants a line above $500,000 gives up leverage to get it, and the line tops out at $1,000,000. The first-lien floor is a 700 score.
How Does the Rent Test Work?
The rent test divides gross monthly rent by a qualifying payment, and the program wants at least 1.10x. That payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a stress payment, so it runs heavier than what you would pay on a partly drawn line.
The qualifying payment is principal and interest only. Taxes and insurance are not part of it. Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market.
A few related rules apply:
- A lease in place is required.
- Whether the first-mortgage payment joins the qualifying payment on a second lien is not something you should assume. Confirm on the file how the lender treats it, because the lender’s own coverage calculation governs.
Here is why this matters for sizing. Because the test runs on the whole limit, a line sized bigger than you need makes the coverage ratio worse. Picture a rental whose rent clears the test comfortably on a $150,000 line but lands under 1.10x on a $300,000 line. Taking the smaller line may be the only version that qualifies. Asking for less can be the right move.
What Are the Draw Rules?
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 must be at least $5,000 each.
The draw period runs 5 years interest-only on the drawn balance. Then a 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
This is a different animal from the flexible bank line many people picture. The Consumer Financial Protection Bureau describes a HELOC as open-end credit you can draw on repeatedly, with a payment that varies with the balance. That holds here, but with a heavy first draw. So a DSCR line fits an investor who has a use for most of the money now, such as a down payment, renovation or debt payoff. It fits poorly as an unused safety net.
What Does the Valuation Require?
Value drives everything, because value is the denominator in the combined-leverage math. A low valuation shrinks the line.
For lines up to $400,000, the program uses an automated valuation (confidence score of 85 or better) with 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 line size. A first lien and any second lien above $400,000 get a full title policy. Smaller second liens use an owner-and-encumbrance report. Hazard insurance must cover both liens, with flood coverage where required.
Seasoning also applies. 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).
Can an LLC Hold the Property?
Yes, the LLC can stay on title, for investment property only and subject to program terms. The LLC 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 need not be the borrowers on the first mortgage.
This matters because many investors hold rentals in an entity for liability reasons. Some standard investment-property lines require individual or trust title, so an LLC owner may find a bank line impossible even with strong equity.
Which Properties and Borrowers Qualify?
Eligible properties include single-family homes, PUDs, townhomes, two-to-four-unit properties, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. The leverage tiers above govern every property type.
Not eligible on this 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. A property listed for sale in the prior 2 months is out, and so is a property with a solar lien. The line is never offered on your own home or a second home.
Borrowers can be US citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Lendmire is the broker. The lender in the network reviews and approves.
Key Terms Defined
Second lien (junior lien): A loan secured by a property that already secures another loan. The CFPB calls this a second mortgage when a first mortgage exists.
Combined loan-to-value (CLTV): All loans on the property, including the new line, divided by the property’s value.
Draw period: The stretch when you can borrow from the line. On this program, it is 5 years interest-only on the drawn balance.
Subordination: An agreement by a lender to stay behind another lender’s lien. It comes up when you refinance the first mortgage later.
Seasoning: The waiting period a lender wants after a purchase or refinance before it will lend again.
DSCR: Debt service coverage ratio. It measures whether the rent covers the payment.
What If Your First Mortgage Leaves No Room?
If your first mortgage uses 70% or more of the value, a second-lien line has no room. You have three practical paths.
The first is a DSCR cash-out refinance. It replaces the first mortgage with a new, larger loan. That can make sense when the existing first mortgage is not a keeper, though the new first lien re-prices the whole balance. Lendmire’s complete DSCR loans guide walks through that structure.
The second path is waiting. Paydown and appreciation both open room over time.
The third is another property. If you own several rentals, one with a lower first-mortgage balance, or none, may carry the line instead.
Here is how the main options stack up, with each column attributed to its own rules:
| Factor | DSCR HELOC (this program) | DSCR cash-out refinance | Bank HELOC on a rental |
|---|---|---|---|
| Existing first mortgage | Stays in place | Replaced | Stays in place |
| Reviewed on | Rent and credit | Rent and credit, per that program | Credit, income, equity, per bank rules |
| Funds | Revolving line | Lump sum | Revolving line |
| LLC title | Allowed, per program terms | Depends on that program | Often restricted, per bank rules |
If you are weighing bank-side options with personal income, Lendmire’s piece How to Qualify for an Investment Property HELOC When Banks Won’t Do Second Position covers that route.
How Should You Plan the Exit?
Plan the exit before you open the line. If you later refinance the first mortgage, the new first lender will generally want the line paid off or its lender willing to stay in second position. That agreement is not automatic. Check your current first-mortgage documents for any restriction on additional liens before you apply.
It also helps to ask what you will do if the first-mortgage refinance and the line collide. Options include paying the line down from sale proceeds or another property, or refinancing both together into a single loan. A line sized small enough to pay off from planned proceeds is easier to unwind.
Lenders commonly set a credit limit by taking a percentage of the home’s value and subtracting the balance on the first mortgage. That is the same logic as the table above. The only difference is that this program’s percentage and its rent test are written for rentals.
A rental HELOC can also fund a down payment on the next purchase. The line typically closes before that purchase. The purchase lender then decides how it treats borrowed down-payment funds.
Frequently Asked Questions
Can I take a DSCR HELOC if my credit is 700 to 719?
Only in first position. A first-lien line needs a 700 score, but it exists only on a rental with no mortgage. If you keep a first mortgage, the line must be a second lien, and that tier starts at 720. A broker can check whether another structure fits, subject to lender guidelines.
Does a 740 score get me more leverage than a 720?
Not on a second lien. Both reach 70% combined loan-to-value. A 740 score does matter on a first-lien line up to $500,000, where it lifts the ceiling from 70% to 75% LTV. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
How long must I own the rental first?
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).
Do tenants or vacancy block the line?
Tenants do not block it. A lease in place is required, and rent comes from the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A two-to-four-unit property may have at most 1 vacant unit.
Can I borrow over $500,000?
Only as a first-lien line on a rental with no mortgage, and only up to $1,000,000. The ceiling on lines above $500,000 drops to 65% LTV at a 720 score or better. A second-lien line never exceeds $500,000. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
