The Quick Read: It depends on three limits, and the smallest one wins: combined leverage, the rent coverage test, and the program’s line cap. On a second lien, a line typically runs from $50,000 to $500,000 at up to 70% combined loan-to-value (CLTV) with a 720 credit score or better, subject to underwriting. A rental with no mortgage can reach 75% loan-to-value (LTV) on a first lien at 740 or better, with lines up to $1,000,000.
- First lien on a paid-off rental: 75% LTV at 740 or better, 70% at 700 to 739, and 65% on lines above $500,000.
- A rental bought or refinanced recently may have no room at all.
- Figures are ceilings through select programs, never offers, and every file is underwritten individually. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
A DSCR HELOC is a revolving home equity line on a rental you own. The rent qualifies it, not your paycheck. The sections below show how the amount is built, which limit binds first, and what that means if you plan to use the cash for your next purchase.
How Is the Maximum Line Calculated?
The line is a subtraction problem. Multiply the maximum leverage by the property’s value, subtract what is already owed against it, then cap the result at the program’s line limit. Whatever is smallest after the coverage test is your ceiling.
On a second lien, the math uses CLTV, meaning the first mortgage balance plus the new line, divided by value. Take a rental valued at $500,000 with a first mortgage balance that is 50% of value. At the 70% CLTV ceiling, the new line can use about 20 points of value. Same property, same value, but a first mortgage near 65% leaves almost nothing.
A first lien works differently. It sits alone on a rental with no mortgage, so the 75%, 70%, or 65% LTV applies to the full value. The tier depends on your credit score and line size. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Here are the tiers in one place, all subject to underwriting:
| Lien position | Credit score | Leverage ceiling | Line range |
|---|---|---|---|
| Second lien | 720 or better | 70% CLTV | $50,000 to $500,000 |
| First lien (no mortgage) | 740 or better | 75% LTV | Up to $500,000 |
| First lien (no mortgage) | 700 to 739 | 70% LTV | Up to $500,000 |
| First lien (no mortgage) | 720 or better | 65% LTV | Above $500,000 to $1,000,000 |
Two cautions on those numbers. A declining-market flag on the property lowers the ceiling by 5 points. And a first lien exists only on a rental with no mortgage. If you keep a first mortgage, the line is a second lien, and that route starts at a 720 score.
What Does the Rent Test Do to the Amount?
The rent test can cap the line before leverage does. The minimum coverage is 1.10x: gross monthly rent divided by a qualifying payment. 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, not what you will actually owe.
Because the test runs on the whole line, not just what you draw, a bigger line demands more rent. Taxes and insurance are not part of the qualifying payment. On a second lien, confirm on the file how the lender treats the first-mortgage payment, since the lender’s own coverage calculation governs.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. The appraisal’s market rent comes from the Form 1007 rent schedule. A lease must be in place. On a two-to-four-unit property, at most one unit can be vacant.
Think of it as two gates. Leverage asks how much equity is there. Coverage asks whether the rent can carry a line that size. A rental with big equity and thin rent can hit the coverage wall first. A high-rent property with a big mortgage hits the leverage wall first. This is why the same property can support very different lines depending on how it is financed.
Qualification runs on the rental’s income: no traditional personal-income documentation, W-2s, pay stubs, or personal income calculation, subject to lender guidelines. The credit report, lease, and valuation are all documented.
Why Might a Recent Purchase Have No Room?
A recent purchase usually leaves little or no borrowable equity. If you financed near the top of the leverage range, the first mortgage already uses the CLTV room. The line has nothing left to fill.
Timing matters too. 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).
Picture an investor who bought a duplex with a high-leverage first mortgage and wants to pull equity right away. Both clocks and the leverage math work against that plan. Compare that with a landlord who has owned a rental for years, paid down the mortgage, and watched the value climb. Same program, very different line.
Can the Line Fund a Down Payment on the Next Rental?
Yes, as a source of cash, with a sequencing rule. The line is never closed together with a purchase. It is written on a rental you already own, and it must be in place on its own. You then use the proceeds toward the next property.
Here is how the sizing works in practice:
1. Work out the down payment percentage you need on the next purchase. 2. Compare that to the line your equity and rent can support. 3. Remember that 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.
That last point changes the plan. You cannot open a large line and leave most of it unused, so the line should be sized close to what you will actually deploy. Later draws are at least $5,000 each.
The purchase lender on the next property has its own view of borrowed down-payment funds. Ask about that before you commit. A DSCR purchase loan typically looks at the property’s rent, and how it treats a new lien on another rental is a question for that file.
How Do Draws, Repayment, and Cost Work?
The draw period is 5 years of interest-only payments on the drawn balance. Then a 25-year fully amortizing repayment period follows, for a 30-year maturity. The rate is variable.
Two risks come with that. A mostly drawn line starts accruing interest on the full balance from day one. And the payment steps up when the draw period ends, because principal begins amortizing. Stress-test your rental’s cash flow against both before you draw.
A variable rate means the payment can move. The rate and the pricing terms come with the lender’s disclosures, so read those before you sign. Lendmire is a broker and does not set them.
A HELOC places a lien on a performing rental. If cash flow tightens while the line is mostly drawn, you carry a second payment on the same property. That is the real cost of this tool, beyond the interest.
What Documents and Property Rules Apply?
The file is built around the property, not your personal income. Expect the current lease, the first-mortgage statement if you keep one, the insurance declaration, and the vesting deed. If title is in an LLC, entity documents join the file.
An LLC can stay on title, subject to program terms, and it works for investment property only. 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 need not be the borrowers on the first mortgage.
Valuation follows line size. Lines 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.
Other file facts, subject to underwriting:
- No reserves and no cash to close are required.
- Mortgage history shows no 30-day late in the last 12 months.
- 48 months must have passed since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
- Exposure is capped at 5 loans or $2,500,000 per borrower with the program.
- Borrowers must be US citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Eligible property types include single-family, PUD, townhome, two-to-four units, and condominiums, plus lots to 10 acres. Rural-designated property, condotels, row homes, and leaseholds are outside the program. So are land trusts, mixed-use, and a property listed for sale in the prior 2 months.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. For a fuller look at how these loans work, see the complete DSCR loans guide.
Why Are Rental HELOCs Harder to Find Elsewhere?
Fewer lenders offer them. NerdWallet says a HELOC on an investment property is harder to get than one on your home, with a smaller lender pool, smaller borrowing amounts, and stricter requirements, and that multiple appraisals may be required. Investors also report local banks and credit unions offering rental lines, according to BiggerPockets, though results differ by institution.
Those lines generally lean on your personal income and debts. A rent-qualified line shifts the test to the property. Lendmire’s piece How to Qualify for an Investment Property HELOC to Invest for Landlords Ready covers that personal-income route.
Borrowing against your own home to buy a rental is a different, owner-occupied product. It puts your home at risk, and this line is never offered on an owner-occupied home.

CLTV: Combined loan-to-value, the first mortgage balance plus the new line, divided by the property’s value.
Draw period: The stretch when you can take money from the line and pay interest only on what you have drawn.
Stress payment: A qualifying payment calculated above the start rate to test whether the rent has a cushion.
Seasoning: The waiting period required after you buy or refinance a property before you can borrow against it.
Lien: A legal claim on the property that secures a loan, with first lien paid ahead of second.
Frequently Asked Questions
Can I use a DSCR HELOC on a rental held in an LLC?
Yes, subject to program terms. The LLC can stay on title for an investment property. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument.
How long must I own the rental before borrowing against it?
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 I need to keep my first mortgage?
You can keep it. The line then sits behind it as a second lien, with a 720 credit score minimum and up to 70% CLTV. If the rental has no mortgage, the line can be a first lien instead.
Does it matter how I use the money?
The line is written on a rental you own, and the proceeds are your cash to deploy, such as a down payment on another property. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
What is the most I can borrow?
Lines run to $500,000 on a second lien and to $1,000,000 on a first lien, with leverage tiers stepping down as the line grows.
