Best Investment Property HELOC Program to Cover a Down Payment on Another Home

The Quick Read: A HELOC can fund your next down payment, but only when two separate approvals line up: the line on an existing property, and a purchase loan that accepts borrowed cash, with the best program for your situation set by your equity, credit, and the new rental’s rent coverage. Different lenders approve each piece, so check the purchase loan’s rules before you draw a dollar.

• An investment-property line on our network tops out at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit score.
• Most DSCR purchase files run 75%-80% loan-to-value, so a 20%-25% down payment is the usual target.
• Many DSCR programs accept borrowed funds for the down payment and closing costs, but usually not for reserves.
• The line’s payment sits outside the DSCR ratio, yet it still hits your real cash flow.

How Does the Two-Loan Sequence Work?

You need two approvals, and the order matters. The line comes first, because you cannot draw from a line that has not closed. The purchase loan then underwrites the new property, and it decides whether your drawn cash is acceptable.

1. Pick the collateral. The line can sit on your primary home or on a rental you own. The next section compares the two.

2. Close the line before you shop. Drawing happens after closing, so a line you plan to open “later” cannot support an offer today.

3. Check the purchase lender’s rules on borrowed funds. Ask whether line proceeds count toward the down payment, closing costs, and reserves. Ask whether any share of the down payment must be your own unborrowed cash.

4. Draw and park the cash in your own account. Keep the deposit, the draw confirmation, and the wire trail together. Some lenders also want the funds to sit for a period, and that period varies by program.

5. The purchase loan reviews the property’s rental income. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio is gross monthly rent divided by the new property’s PITIA (principal, interest, taxes, insurance, and any association dues).

6. Plan the exit. Know in advance how you will repay the line from rents, a sale, or a refinance.

Our wholesale network has many DSCR lenders, and they do not all treat step three the same way. That is why a broker who shops several lenders matters more here than on a plain purchase.

Which Property Should Secure the Line?

Your primary home is the easiest to borrow against, and a rental is the harder but often safer choice for the household. The right answer depends on how much equity each property holds and which asset you can stand to put at risk.

A line on your home puts your residence behind the new purchase. A line on a rental puts that rental behind it instead. Experian notes that lines on investment property are generally harder to qualify for and not every lender offers them. On our network, an investment-property line tops out at 70% CLTV.

The LLC column matters most. HELOC title must be held by you personally or by a revocable living trust. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead. DSCR purchase loans can close in an LLC, subject to lender program eligibility.

What Does an Investment-Property Line Look Like on Our Network?

Across the wholesale partners we place these files with, an investment-property line has a narrow, predictable box. These figures are program guidance, not promises, and every file is reviewed individually.

• Leverage: 70% CLTV on an investment property. Credit above 700 does not buy more leverage, because 720 and 700 reach the same ceiling.
• Line size: $25,000 to $500,000 on an investment property.
• Credit: 700 minimum, with no tier below it.
• Debt-to-income: 50% maximum, qualified on the interest-only payment at the maximum draw.
• Structure: a first or second lien, with a 5-year interest-only draw followed by a 25-year fully amortizing repayment.
• Draw at closing: at least 75% of the line is drawn when the line closes. Later draws start at $1,000.
• Pricing: it floats through both the draw and the repayment period and never converts to fixed.
• Valuation: because the cap is $500,000, an investment line is generally valued with an automated model rather than a traditional appraisal, though you can request one.
• Property types: single-family, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
• Exposure: up to three lines per borrower, and owners with more than 15 financed properties are not eligible.
• Availability: HELOCs are offered in 16 full-service states (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA). That is narrower than the 41-market DSCR footprint, which includes Washington, D.C.

The draw-at-closing rule has a practical side effect. You may carry more borrowed cash than the down payment needs, and you will pay on it. Size the line to the deal, not to the maximum.

What Does the Purchase Lender Need to See?

The purchase lender looks at three buckets separately: the down payment, the closing costs, and the reserves. Borrowed funds are commonly accepted for the first two. They are usually excluded from reserves, and the undrawn part of a line generally does not count as reserves at all.

Here is how most DSCR purchase programs in our network behave:

• Leverage: most purchases land at 75%-80% loan-to-value, which means 20%-25% down. Select high-leverage programs reach 85% (15% down) at roughly a 700+ score.
• Coverage: 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
• Reserves: commonly around six months of PITIA. They vary by lender, leverage, loan size, and transaction type, and larger loans typically step up.
• Borrowed-share rules: a few programs cap the borrowed share. The strictest overlays want part of the down payment to be your own unborrowed cash.

Big banks and large retail lenders often insist the down payment be your own money, because cash builds equity. DSCR programs set their own rules, so the answer on one file does not predict the next.

The HELOC payment does not enter the DSCR ratio on most purchases. The ratio compares the new property’s rent to that property’s own PITIA. Your finances still carry two obligations, though. Clearing 1.00 also does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.

Worked Example: Funding the Down Payment, Then Stress-Testing It

Say you own a rental with a first mortgage and solid equity. These are modeled assumptions, not market data.

Your line is sized so the first mortgage plus the line stays at or under 70% CLTV, and under the $500,000 cap. You then buy a second rental at 75% loan-to-value on a purchase, so the down payment is 25%. If the line covers all of that 25% plus closing costs, you are close to fully financed.

On paper, the new property’s rent clears roughly 1.2x against its own PITIA, so it passes a 1.00 coverage test with room to spare. Now run the harder tests:

1. Vacancy. Assume the unit sits empty for two months. The new mortgage and the line both still come due.

2. Payment step-up. The line’s interest-only draw lasts five years. When the 25-year amortizing repayment begins, the payment can rise.

3. Floating pricing. The line never converts to fixed, so the payment can move at any point.

If the deal only works while the line stays interest-only and the unit stays full, re-examine it. That is the test we apply to every borrowed-down-payment file. A rental still stabilizing when the draw period ends is the most exposed.

Where the General Rule Breaks

The general rule is that a line plus a purchase loan works if equity, credit, and rent coverage all clear. Several edge cases bend it.

Rental-use restrictions. The CFPB’s HELOC booklet is written for owner-occupied homes. It warns that renting out your home may be prohibited under the terms of your line, so read the line agreement’s occupancy and use language before you draw.

A line is a second mortgage. If the property already carries a first loan, the line sits behind it. The CFPB also warns that if you fall behind, you could lose the home securing the line.

Line size versus price. If the purchase needs 25% down and your line supplies 20% of the old property’s value, the line covers the whole down payment only when the new price is modest relative to the old property’s value. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

Near-total leverage. A fully borrowed down payment means two separate loans and almost no cash of your own in the deal. Some programs will not allow it.

Sub-1.00 coverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Paired with a borrowed down payment, those files get tighter fast.

Entity titling. An LLC cannot hold the line, as covered above.

Availability. Investment-property lines are available only in 16 states, and some lenders stop offering them. A rental-based line may not exist where you live.

Key Terms Defined

HELOC: a home equity line of credit, a revolving line you borrow against during a draw period and repay afterward.

CLTV: combined loan-to-value, the total of all loans against a property divided by its value.

DSCR: debt service coverage ratio, a property’s gross monthly rent divided by its monthly PITIA.

PITIA: principal, interest, taxes, insurance, and any association dues, the full monthly cost of owning the property.

Seasoning: the waiting period a lender wants funds to sit in your account, or a loan to age, before it counts.

Reserves: liquid cash left after closing, measured in months of PITIA.

What “Best” Means for This Use

No single program wins for everyone. The best program for your situation depends on these criteria:

• Property type: does the collateral fit the eligible list?
• Title: are you holding it personally or in a revocable trust?
• Combined leverage: does the line plus the first loan stay under the CLTV ceiling?
• Line size: will the cap leave you enough cash for the target price?
• Draw structure: can you live with a payment step-up and floating pricing?
• State availability: is the product offered where the collateral sits?
• Purchase-side acceptance: will the DSCR lender take borrowed funds?

A broker that shops multiple wholesale lenders can match your answers to a program before you commit. A single lender’s page cannot do that.

Who Fits, and Who Should Skip It

This fits an investor with real equity in a rental or home, a 700+ score, and a purchase where the new rent covers its own payment with margin. It also fits an investor who wants to keep savings liquid for repairs and reserves.

It does not fit an investor whose only reserves would come from borrowed cash, whose title sits in an LLC with no plan to change it, or whose deal works only when the down payment is borrowed. For those borrowers, a DSCR cash-out refinance on the existing property is often the cleaner path, and the complete DSCR loans guide walks through that comparison.
