Top Investment Property HELOC Providers to Cover a Down Payment on Another Home

The Quick Read: A HELOC can fund the down payment on another rental, but it only supplies cash: a separate loan still buys the property, and no ranked list of providers can pick the right line for you because the best fit depends on your equity, credit, property type and combined leverage across both properties. Lendmire is a mortgage broker, not a lender. It shops a network of wholesale HELOC lenders and matches your scenario to a program, so this guide explains how those programs work instead of naming companies.

• On an investment property, the network’s HELOC ceiling is 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000.
• On a primary residence, the ceiling reaches 90% CLTV, but only at a 720 or better credit profile.
• The line and the purchase loan are two separate approvals with two separate payments.
• Clearing 1.00 on the new rental’s coverage ratio does not mean the property cash flows, and it says nothing about the HELOC payment.
• The program is available in Lendmire’s 16 full-service states, which is narrower than its DSCR footprint of 41 markets, including Washington, D.C. Every figure here is subject to lender guidelines and full file review.

What an Investment-Property HELOC Actually Does

A HELOC is a revolving credit line secured by a property you already own. You borrow against the equity, which is the property’s value minus what you owe. The cash lands in your account. You then use it as the down payment on a different property, financed by its own loan.

That separation matters. The line does not buy anything. It changes where your down payment comes from, so you can keep savings in place and skip a refinance of your current first mortgage. Experian describes this use and adds that lines secured by rentals are less common and harder to qualify for than lines on a primary home. That is why shopping matters.

On this network, the line is a standalone product. It can sit in first or second lien position, which means it can be your only loan on the property or sit behind an existing mortgage.

Key Terms Defined

CLTV (combined loan-to-value): Your first mortgage plus the new line, divided by the property’s value.

Lien position: Your place in line to be repaid if the property is sold. First comes before second.

Draw period: The stretch when you can borrow from the line and pay interest only.

Repayment period: The stretch after the draw period when the balance amortizes, meaning each payment includes principal.

DSCR (debt service coverage ratio): A purchase-loan test that divides the new property’s rent by its monthly payment of principal, interest, taxes, insurance and any HOA dues.

Source of funds: The paper trail showing where your down payment came from.

How Underwriting Treats the Line, Step by Step

The HELOC lender looks at you and the collateral. The DSCR purchase lender looks mainly at the new property’s rent against its own payment. Each lender runs its own file, and neither one approves on the other’s behalf.

Here is the HELOC side, in order:

1. Equity sizing. The lender takes a percentage of the property’s value and subtracts what you owe. On an investment property in this network, that percentage is capped at 70% CLTV.

2. Credit. The program uses a single-bureau score, keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed. An investment line requires a 700 minimum, with no tier beneath it.

3. Debt-to-income. The ceiling is 50%. The lender reviews your file on the interest-only payment calculated on the maximum draw, not just what you borrow on day one.

4. Valuation. An investment line tops out at $500,000, and full appraisals start above that. So an investment line sits in the automated-valuation lane and commonly closes with no traditional appraisal. You can still request a full appraisal.

5. Title. The property must be held by you personally or by your revocable living trust.

6. Draw. At least 75% of the line is drawn at closing. Plan for that when you pick the line size.

The CFPB’s HELOC booklet explains the same equity logic: the limit is a percentage of the home’s value minus what is owed. That booklet is old, so treat it as a concept guide, not a program source.

Which Property Should Secure the Line?

Your primary home usually gets you more room. The network treats occupancy in tiers.

Two wholesale programs sit behind these lines: one built for higher leverage and one with a longer repayment runway. That is why the credit figure splits above $500,000. The two numbers belong to two programs, so they do not contradict each other.

Investment credit above 700 buys eligibility rather than leverage, since 700 and 720 both reach 70%. Lines above $500,000 are for primary residences only.

So which collateral wins? The primary residence usually offers more borrowing room. The rental keeps your home out of the loan chain. That is a genuine toss-up, and the answer turns on how much equity each property carries and how comfortable you are putting your home behind a line that funds an investment. Primary-residence lines come in two draw structures: a 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. Investment lines run the 5-year draw and 25-year repayment only.

The Structure: Draw, Repayment and Stacked Payments

The line floats. Pricing moves across both the draw and the repayment period, and it never converts to fixed. Expect the payment to change even if you borrow nothing more. When repayment starts, the payment steps up because principal joins the interest.

The CFPB’s HELOC explainer also notes that a lender can stop further draws if the property’s value falls significantly. And if you fall behind, the property securing the line is at risk. A Benzinga overview lists the same downsides: added debt and foreclosure exposure on the collateral.

Now stack it. After the purchase, you carry the first mortgage on the old property (if any), the HELOC payment, and the new loan’s payment. Only the new loan’s payment sits inside the coverage ratio.

DSCR compares rent to the new property’s payment only. Repairs, vacancy, management, utilities and capex all sit outside the calculation. A property can clear 1.00 and still lose money after the HELOC payment.

Run the numbers on a simple setup. Say your existing rental carries a first mortgage equal to 45% of its value. A 70% CLTV cap leaves room equal to 25% of that value. A purchase at 75% LTV needs 25% down, so the line could cover the down payment on a property of similar value, before closing costs and reserves. In that case the new first mortgage covers 75% and the line covers the other 25%, so the purchase itself needs little cash of your own. The cost is that you now owe on two properties at once. If the new property sits vacant, the rent that was meant to cover its payment disappears, yet the first mortgage on the old rental, the HELOC payment and the new loan’s payment all still come due. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

Where the General Rule Breaks

LLC-held properties. The line cannot be secured by a property titled in an LLC, corporation, partnership, or an irrevocable, blind or land trust. This is the sharpest structural difference from a DSCR loan, where an LLC borrower can work subject to lender program eligibility. If your rental already sits in an LLC, you need a vesting change first, or a DSCR cash-out refinance instead.

Borrowed money and reserves. Whether a purchase lender accepts HELOC proceeds for the down payment is a program-level decision. Ask before you draw. Disclose the source. Do not try to blur it by parking cash in an account.

Prepayment penalties. Many DSCR purchase loans carry a prepayment penalty period. If you plan an early refinance to pay off the line, check the penalty first. The two plans can collide.

Exposure limits. A borrower is limited to three lines, with combined exposure capped at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower owning more than 15 financed properties is not eligible.

Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure or short sale needs 4.

Property types. Single-family, 2-4 units, PUDs, townhomes and condominiums (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not offered.

How to Pick Top Investment Property HELOC Providers for a Down Payment

No honest list of top investment property HELOC providers can rank them for you. The best program for your situation depends on your property type, credit profile, leverage need, and how much documentation you can show. Overlays also differ from one lender to the next, so compare guidelines rather than names.

You will meet four types of providers: depository banks, credit unions, online lenders and brokers. A bank or credit union where you already hold accounts is a fair first call, but you get one lender’s guidelines. A broker like Lendmire places the file with one of its wholesale lenders after matching credit, equity, property type and structure. That means one application can be tested against several sets of guidelines.

Here is how the main paths compare.

Questions to ask any provider:

• Does the draw come as a lump sum, and how much must be drawn at closing?
• Can I convert any portion to fixed? (On this network, no.)
• What does repayment look like, and does a balloon apply?
• Will the purchase lender accept this line for my down payment, and for reserves?
• Does my property title and type qualify?

What the Decision Looks Like in Practice

Start with the purchase loan, not the line. On most DSCR files in the network, purchases land at 75%-80% LTV, meaning 20%-25% down. Select programs reach 85% LTV with about a 700+ score. Credit floors start at 620 in parts of the network, most programs want around 660, and 700+ unlocks the strongest tiers. Coverage of 1.00 is where select programs start, while a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. A higher ratio often improves terms. A bigger down payment helps the ratio but never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. For the full framework, see the complete DSCR loans guide.

Then work backward. Ask the purchase lender about borrowed funds before you draw. Underwrite the deal as if the HELOC payment were a real operating expense. Decide in advance how you will pay the line down, whether from a refinance, a sale, or ordinary cash flow.
