The Quick Read: It depends on the equity a rental you already own has left under a 70% combined loan-to-value ceiling on a second lien, up to a $500,000 line, and on whether your purchase lender accepts that borrowed cash, because the line only supplies money and a separate DSCR purchase loan buys the new rental.
- The limit is the property’s value times the combined ceiling, minus what is already owed on it.
- Second-lien lines run from $50,000 to $500,000. A first lien on a paid-off rental can reach $1,000,000, with a lower ceiling above $500,000.
- The rent has to cover a stress payment on the entire line, not only the part you draw.
- The line cannot sit on the property you are buying, and it closes before the purchase does.
- Some purchase programs accept documented borrowed funds as the whole down payment, some cap the borrowed share, and some want part of it from unborrowed cash.
How Is the Maximum Line Calculated?
The maximum line is the rental’s value times the program’s combined ceiling, minus every lien already on the property. A dollar cap then trims the result if it is higher. The line is the smaller of those two numbers, and the lender’s valuation sets the value.
Combined loan-to-value (CLTV) is the first mortgage balance plus the new line, divided by the property’s value. A Yahoo Finance explainer describes the same math for ordinary home equity lines, and it says many lenders allow 80% to 85% of value on a primary residence. That is a consumer-market figure. On a rental in the DSCR HELOC program Lendmire places files with, the second-lien ceiling is 70% CLTV on an investment property, at a 720 credit score or better.
Run it as percentages. Say the rental carries a first mortgage equal to 50% of its value. A 70% CLTV ceiling leaves room for a line worth about 20% of value. If the first mortgage is 65% of value, only about 5% of value is left. Lines start at $50,000, so a thinly equitied rental may not support the smallest line at all.
The percentage and the dollar cap work as a pair. On a high-value rental with no mortgage, the $500,000 cap or the first-lien ceiling can bind instead. These figures are ceilings, not offers, and every file is underwritten individually.
Key Terms Defined
DSCR HELOC: A revolving line of credit secured by a rental you keep, qualified on the property’s rent instead of your personal income.
CLTV (combined loan-to-value): All debt secured by the property, including the new line, divided by the property’s value.
Second lien: A loan that sits behind the first mortgage you keep in place.
First lien: A loan in first position, available on a rental with no mortgage.
Draw period: The stretch when you can borrow from the line and pay interest only on the drawn balance.
Stress payment: A fully amortizing payment calculated on the entire credit limit at a higher assumed cost, used only to test coverage.
Which Property Can Hold the Line?
The line sits on a rental you already own, either as a second lien behind your first mortgage or as a first lien on a rental with no mortgage. It is never written on your own home or on a second home. It also cannot be a third lien.
That last point surprises people. You cannot secure the line with the property you are trying to buy. The cash has to exist before you go under contract.
| Factor | Second lien | First lien |
|---|---|---|
| Property status | Rental with a mortgage you keep | Rental with no mortgage |
| Credit floor | 720 | 700 |
| Leverage, up to $500,000 | Up to 70% CLTV | 75% LTV at 740+, 70% LTV at 700-739 |
| Lines above $500,000 | Not available | 65% LTV at 720+, to $1,000,000 |
Every figure applies to an investment property and is subject to underwriting. If you keep a first mortgage, you can only take the second lien, so the 720 floor is the one that matters.
The program accepts single-family homes, townhomes, planned developments, two-to-four-unit properties, and warrantable and non-warrantable condominiums. It does not accept rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, or mixed-use. A property listed for sale in the prior two months is out, and so is one with a solar lien. A declining-market flag lowers the ceiling by 5 points. The owner’s LLC can hold title, subject to program terms, with the members signing as guarantors.
What Else Limits How Much You Can Pull?
Four things beyond the equity formula decide the final number: the rent test, the valuation path, the draw rules, and the ownership clock. Any one of them can shrink the line below what the CLTV math alone suggests.
The rent test. The line needs at least 1.10x coverage. That is gross monthly rent divided by a stress payment on the entire credit 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 in place is required. A two-to-four-unit property can have at most one vacant unit.
Taxes and insurance are not part of that qualifying payment. Whether your first-mortgage payment joins the coverage calculation on a second lien is something to confirm on the file, because the lender’s own calculation governs.
Because the stress payment covers the whole limit, a larger line raises the hurdle even before you borrow a dollar. A rental with strong equity but modest rent can have room on the CLTV side and still be limited by coverage. Sizing the line smaller can fix that.
The valuation. 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. The value that comes back, not your estimate, sets the equity.
The draw rules. At least 80% of the line is drawn at closing, and that closing draw is never below $50,000. On the smallest lines, that means the whole line is drawn up front. Later draws are at least $5,000 each. The draw period is 5 years, interest-only on the drawn balance, followed by a 25-year repayment period and a 30-year maturity. The rate is variable.
For a down-payment plan, this means most of the line becomes cash on day one and starts costing you interest. Size the line to the cash you need, not to the maximum.
The ownership clock. 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 and borrower limits. The program allows at most 5 loans or $2,500,000 per borrower. Borrowers must be U.S. citizens, permanent residents, or non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible. The line is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, and it requires no reserves and no cash to close.

Will the Purchase Lender Accept Borrowed Money?
Often yes, but not always in full. The line gets you the cash. The DSCR purchase lender then decides how much borrowed money counts toward your down payment, and programs split three ways on that.
Across a wholesale network, you see the full range:
- Some programs accept documented line draws as the entire down payment.
- Some cap the borrowed share.
- The strictest overlays want part of the down payment from unborrowed funds.
Borrowed funds are also commonly excluded from reserves, even after they are drawn. Down payment, closing costs, and reserves are three separate pots, and a program may accept borrowed money for one and not another. The line itself requires no reserves, but the purchase loan may.
Unsecured borrowing, such as a credit card cash advance, is generally not an acceptable source. A line secured by an asset you own, with a clear paper trail, is treated differently.
The purchase loan is tested on its own. It looks at the new rental’s rent against that property’s own payment. The line’s payment generally does not enter that ratio. A bigger down payment also shrinks the purchase loan, which can lift the new property’s coverage whether the cash was borrowed or not.
Ask the purchase lender three questions before you draw anything:
1. Do you accept line proceeds as the down payment, and is there a cap on the borrowed share?
2. Do you count any borrowed funds toward reserves?
3. What documents prove the source: the line agreement, the draw confirmation, and the deposit trail?
Can the Line Cover the Whole Down Payment?
It covers the whole down payment only when the new purchase is modest compared with the equity you are tapping. The test is a ratio, not a rule of thumb.
Suppose your purchase program asks for 25% down, as a hypothetical. Suppose the line equals 20% of your existing rental’s value. The line then covers the full down payment only if the new purchase price is no more than 80% of that rental’s value. Above that, you bring the difference from your own cash. Closing costs and reserves come on top. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
A line never removes the down payment. It changes where the cash comes from.
Compare the three ways to fund it:
| Funding path | Effect on you |
|---|---|
| All your own cash | Smallest total debt; no extra payment |
| Partly borrowed | Two obligations; moderate extra carry |
| Fully borrowed | Total borrowing near the full purchase price; most carry |
The more you borrow, the closer your combined debt comes to the new property’s full price. That is leverage across two rentals, and it works only while both rents hold.
What Does the Draw Do to Your Cash Flow?
The line’s payment does not usually count in the new loan’s coverage ratio, but it still leaves your bank account. During the draw period you pay interest on the drawn balance. After five years, the 25-year repayment period begins, and the payment steps up because principal is added.
Say you draw the minimum 80% at closing, buy a new rental, and then renovate it for several months. The line is paying interest the whole time, and the new rental’s loan payment is due too. Neither property needs to be vacant for that to hurt, because a repair or a slow lease-up is enough.
The CFPB describes a HELOC as an open-end line you can borrow against repeatedly, with a draw period followed by repayment. It also advises considering one only if you are confident you can keep up with payments. That advice holds with extra force when the line is funding a purchase that has not yet produced rent.
Stress-test the plan before you commit. Ask whether both properties still carry themselves if one rent drops or one month goes vacant. If the answer depends on everything going right, the line is too large.
When Should You Skip This Strategy?
Skip it when the numbers only work at the maximum line, or when the purchase lender will not take borrowed funds.
Several situations call for a different route:
- Thin equity. If the formula leaves less than the $50,000 minimum, the line is not available.
- Weak coverage. If rent sits near the 1.10x test on the full limit, a smaller line or a different structure may fit better.
- A recent purchase or refinance. The 6-month clocks apply.
- A need for the largest possible payout. A DSCR cash-out refinance is built for that, while the line fits an owner who likes the current first mortgage and wants a defined sum.
- The source is your own home. A consumer HELOC on your residence is a different product, underwritten on personal income and debts. It puts your home at risk. A lender may also restrict renting the home out.
Lenders also typically ask you to keep some equity in the property as a cushion. The CFPB’s guide to using home equity puts that cushion at 10% to 20% of home value for consumer loans. The DSCR HELOC’s own ceilings already leave a cushion of at least 25% to 30% of value.
A Short Pre-Draw Checklist
Before you open a line for a down payment, line these up:
- The rental’s current value estimate, first mortgage balance, and any other liens.
- A lease in place, plus rent receipts if the lease exceeds market rent.
- Credit at 720 or better for a second lien, or 700 or better for a first lien.
- Written confirmation from the purchase lender about borrowed funds.
- A cash-flow plan that shows both payments carried at once.

Frequently Asked Questions
Can I use a DSCR HELOC as the full down payment on another rental?
Sometimes. Some purchase programs in a wholesale network accept documented borrowed funds as the entire down payment. Others cap the borrowed share, and the strictest want part of it from unborrowed cash. Confirm the purchase lender’s rule before you draw, and plan on separate cash for closing costs and reserves.
Does the HELOC payment count against the DSCR on the new rental?
Generally no. The purchase loan is tested on the new property’s rent against its own payment. The line’s payment still comes out of your real cash flow, so it affects whether you can carry both properties even when it stays out of the ratio.
How soon after buying a rental can I open a line on 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). Both must be satisfied before the line is available.
Can I put the line on the property I am about to buy?
No. The line goes on a rental you already own, and it closes separately and before the purchase. It is never written together with an acquisition.
Do I need traditional personal-income documentation?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The rent, the lease, your credit report, and the valuation are all documented. Your personal income is not calculated.
