Best Investment Property HELOC Program for a Rental Down Payment

The Quick Read: The right program depends on which property secures the line, because a line on your primary home reaches higher leverage than a line on an existing rental, and the purchase loan is a separate approval either way.

• A home equity line of credit (HELOC) is a cash source for the down payment. It does not buy the rental.
• On our wholesale network, an investment-property line caps at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit score.
• A line on a primary residence reaches up to 90% CLTV, but only at a 720-or-better credit profile.
• Purchase loans on rentals usually land at 75%-80% LTV, so the line has to cover a real down payment plus closing costs.
• Open the line before you go under contract, and make sure rent can carry the new loan and the line together.

What Does “Best” Mean for a Down-Payment Line?

The best program for your situation is the one that matches four things: the property securing the line, who is allowed to hold title, how much leverage you need, and whether the purchase lender will accept the borrowed funds.

Lendmire is a mortgage broker, not a lender. It places HELOC files with select wholesale lenders and matches the scenario to a program. The lenders that write a given file depend on your property type, credit profile, and how much cash you need. Every figure below is subject to lender guidelines and full file review.

• Collateral: Your primary home, a rental you already own, or a different loan type entirely.
• Title: Lines on our network require the borrower to hold title individually or in a revocable living trust.
• Leverage: The ceiling changes with occupancy and credit tier.
• Purchase-lender view: Borrowed funds are usually fine for down payment and closing costs. They are commonly excluded from reserves.
• Carry: Your cash flow has to support two payments, not one.

The Three Routes (and What Each Costs You)

You have three realistic routes, and each one puts a different asset at risk. A line on your home puts the home at risk. A line on a rental puts the rental at risk. A cash-out refinance replaces an existing loan instead of adding one.

Market surveys report that lenders typically cap investment-property HELOC LTV at 80%, according to Experian. On our network, an investment-property line stops at 70% CLTV, and no credit tier lifts it higher. A 720 score and a 700 score both reach 70%, so credit above 700 buys eligibility rather than extra leverage.

The primary-residence route is the common one. It gives you the highest ceiling, and a 90% CLTV figure exists only for 720-or-better files. The tradeoff is that your own home secures money you spend on a rental.

How the Purchase Lender Treats the Borrowed Money

A HELOC and a rental purchase loan are two separate approvals. The line is judged on the equity, credit, and debt ratios behind the property that secures it. The purchase loan, usually a DSCR loan, is judged mainly on the new property’s rent against its own payment.

DSCR stands for debt service coverage ratio. It divides monthly rent by PITIA, which is principal, interest, taxes, insurance, and any HOA dues. Our complete DSCR loans guide walks through that math in detail.

The HELOC payment generally does not enter that ratio. It still comes out of your pocket every month. Many investors miss that point, and a few lenders on a conventional file do count the line payment against you.

Purchase lenders treat a draw as a sourcing question. Across the wholesale network, borrowed funds are commonly accepted for a down payment or closing costs when you document them. Reserves vary by lender, leverage, and loan size, and many files ask for about six months of PITIA.

So a line can cover the 20%-25% down on a typical purchase, but it will not satisfy a reserve requirement. Keep some real cash on hand for that. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

What Qualifies You for the Line

An investment-property line is reviewed on you, not on rent. The main standards on our network look like this:

• Credit: A 700 minimum on an investment line, with no tier below it.
• Debt-to-income: A 50% maximum, qualified on the interest-only payment calculated on the maximum draw.
• Line size: $25,000 to $750,000 overall, but an investment line stops at $500,000. Anything above $500,000 is primary-residence only, capped at 75% CLTV, and needs a full appraisal.
• Valuation: Lines at or below $500,000 usually run on an automated valuation with no traditional appraisal, so an investment line commonly closes without one.
• Property types: Single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos.
• Not eligible: Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning.
• Exposure: A borrower can hold at most three lines, and an owner with more than 15 financed properties is not eligible.

Title is the sharpest difference from a DSCR loan. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change or a DSCR cash-out instead. A DSCR cash-out can work on an LLC-titled property, subject to lender program eligibility.

A recent bankruptcy needs four years of seasoning from discharge or dismissal. Investment files follow a seven-year path after a foreclosure and four after a deed-in-lieu or short sale. Lines are also limited to 16 states, which is narrower than the 41-market DSCR footprint, so confirm availability early.

Step by Step: From Opening the Line to Closing

The sequence matters because a line cannot sit on a property you have not bought yet. You need the line open and in place before the contract.

1. Choose the collateral. Decide whether the line sits on your primary home or an owned rental.

2. Open the line before you need it. A first-time investor with no existing property to pledge needs a different route, such as savings or a partner.

3. Size the draw to the deal. Cover down payment, closing costs, and a small buffer. On our network, at least 75% of the line is drawn at closing, so a large line you barely need still costs you.

4. Keep the paper trail clean. Save the line agreement, the draw record, and the account statements showing the money moving.

5. Move the funds on a documented path. Draw into your own account, then wire to the title company.

6. Underwrite the purchase separately. The purchase lender checks rent against the new payment on its own terms.

On our network, a primary-residence line runs one of two draw structures: a 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. An investment line runs the 5-year draw and 25-year repayment structure only. Pricing floats across both the draw and the repayment period and never converts to fixed.

The CFPB describes the same pattern for HELOCs in general: you borrow during a draw period, then move to repayment, and the payment can change from month to month. Its HELOC booklet adds that a variable-rate plan’s payment can change even if you borrow no more money. The end of the draw period is the moment many investors underestimate, because principal payments begin.

A Worked Example, Without the Dollar Figures

Say you own a primary home with plenty of equity and a 720-plus credit profile. You plan to buy a rental at 75% LTV, so you need 25% down plus closing costs. You open a line on the home, draw enough to cover that cash, and document the transfer. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

The rent on the new property covers its own PITIA at roughly 1.2x, which clears the 1.00 floor where many select DSCR programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. A ratio above 1.00 does not mean positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the calculation.

Now run the stress test. If the unit sits empty for a stretch, the rental stops carrying its own loan. Your own income then carries the first mortgage, the HELOC payment, and the rental loan together. That is the three-obligation stack, and it is why many investors size the draw conservatively.

The stronger file clears both tests: enough equity for the line and enough rental coverage for the purchase.

Which Route Fits Your Situation?

This one is a genuine toss-up for some borrowers. The line is cheaper to open and lets you keep a good first mortgage in place. A cash-out refinance can be cleaner but replaces the loan you already have. Here is how it usually sorts out.

Where the General Rule Breaks

A few edge cases trip up otherwise strong files.

• A bank declines a line on a rental. Many depository institutions will not write one. A broker can shop multiple wholesale lenders, which is the main advantage over walking into one big retail lender.
• The purchase lender balks at borrowed funds. Acceptance varies by lender, and some want the funds to sit in your account for a period first. Ask before you draw.
• The rental is listed or recently listed. In several states, a property listed for sale within the past 60 days is ineligible.
• Credit sits between 640 and 700. An investment line is closed to you, but a primary-residence line or a DSCR cash-out may not be.
• A larger down payment helps the ratio, not the caps. More cash lowers the payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility.

When Not to Use a Line

Skip the line if your cash flow already runs thin. Skip it if you would need to draw close to the full ceiling, because the payment rises when the draw period ends. Skip it if the rent only just clears 1.00x coverage with no cushion.

If you have plenty of cash, using savings is simpler and avoids a second lien. A lower-priced first purchase can also beat borrowing to reach a more expensive one.

Key Terms Defined

HELOC: A revolving line of credit secured by the equity in a property, drawn as needed.

CLTV (combined loan-to-value): All loans secured by the property added together, divided by its value.

DSCR: Monthly rent divided by PITIA, used to judge whether a rental covers its own payment.

PITIA: Principal, interest, taxes, insurance, and any HOA dues on a property.

Draw period: The stretch when you can borrow from the line, usually interest-only on our network.

Seasoning: The waiting period a lender wants between two events, such as a purchase and a cash-out refinance.

Lien position: Whether a loan sits first or second in line to be repaid if the property is sold.

Next Step

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. Any calculator you use is an illustrative estimate, not a quote.

A line only works as a down-payment tool when the rent can carry the new loan with room to spare.
