Investment Property HELOC Requirements to Cover a Down Payment on a Rental

The Quick Read: A home equity line can fund the down payment on a rental, but only after two separate approvals: the line must close on its own terms, and the DSCR lender financing the next property must accept borrowed money as your down payment source. Both approvals are subject to lender guidelines.

• On an investment property, the line tops out at 70% CLTV and $500,000, with a 700 minimum credit score.
• On a primary residence, the ceiling reaches 90% CLTV, and only at a 720-or-better credit profile.
• The DSCR purchase loan still needs its own leverage, credit, reserve, and rent-coverage tests.
• At least 75% of the line is drawn at closing, so size it to the cash you need.
• Title must sit with an individual or a revocable living trust, not an LLC.

What Is an Investment Property HELOC?

It is a revolving line of credit secured by a home you already own. Here, the home is a rental. The line can sit in first or second lien position, and the borrower draws cash against it.

That cash is not a rental loan. It is a pool of money, and it has to be paired with a purchase loan. For most investors that purchase loan is a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.

Lendmire is a broker, not a lender. It arranges these lines through select wholesale partners, and only in its 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That footprint is narrower than the DSCR program footprint of 40 states plus Washington, D.C. A DSCR purchase can be arranged in a state where the line itself is not offered.

What Does the Line Itself Require?

The line is underwritten as its own file, and the network’s investment-property terms are tight. Occupancy sets the ceiling, so the table below separates the two cases.

Several requirements cut across both columns:

• Credit: The score comes from a single-bureau model keyed to the primary wage earner. The report can be no more than 90 days old at closing, and rescores are not allowed.
• Debt-to-income: The maximum is 50%. It is calculated on the interest-only payment at the maximum draw, not on what you actually borrow.
• Valuation: Because an investment line cannot exceed $500,000, it normally runs on an automated valuation with no traditional appraisal. A borrower can still ask for a full appraisal.
• Property types: Single-family, 2-4 unit, PUD, townhome, and condominium (including non-warrantable) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not.
• Exposure: A borrower is limited to three lines. Anyone owning more than 15 financed properties is not eligible.
• Bankruptcy and foreclosure: A bankruptcy needs 4 years of seasoning. On investment files, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4.

Pricing floats through both the draw and repayment periods and never converts to fixed. The calculator on this site can illustrate the numbers, but it is an estimate and not a quote.

How Does Underwriting Treat the Down Payment, Step by Step?

Underwriting happens in layers, and the order matters. Here is the sequence that works.

Step 1: Qualify for the line. The line lender looks at equity, credit, and DTI. For a rental-secured line, the equity math is straightforward: the first mortgage plus the new line cannot exceed 70% of the property’s value. Say the existing mortgage equals 45% of value. The line could then reach roughly 25% of value, before any other limits apply.

Step 2: Draw before you shop. At least 75% of the line is drawn at closing. That is a design feature, not a choice. A borrower who wants a small cushion on top of a large line still carries the interest-only cost on most of it from the first day.

Step 3: Confirm the purchase lender’s borrowed-funds rule. Across the wholesale network, DSCR programs differ here. Many accept proceeds from a line on another owned property, provided the funds are documented. Some cap the borrowed share. Some want a slice of unborrowed cash. Investors discussing this on BiggerPockets report the same pattern: only some lenders allow a borrowed down payment on a rental purchase.

Step 4: Document the money. Expect to provide the line agreement, the draw record, and the statements showing where the cash landed. The goal is a clean paper trail from the line to the title company.

Step 5: Underwrite the rental on its own numbers. The DSCR loan compares the new property’s rent to its own payment of principal, interest, taxes, insurance, and any HOA dues. The line is secured by a different property, so its payment normally sits outside that ratio. Some lenders still glance at it in the overall picture.

Step 6: Meet the purchase-loan tests. Most purchase files land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV with roughly a 700+ score. Credit typically needs around 660, with a 620 floor in parts of the network. Reserves are commonly around 6 months of PITIA, and borrowed funds are often excluded from counting toward them. Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.

A larger down payment lowers the new loan and can lift the coverage ratio. It never overrides leverage caps, credit floors, or reserve rules. The strongest files clear both tests: enough equity and enough rental coverage. For the full program picture, see the complete DSCR loans guide.

What Structures and Variations Exist?

The main choice is which property secures the line. A line on an existing rental keeps your personal residence out of the picture. It also depends on that rental being seasoned, owned in your own name or a revocable trust, and worth enough to leave room under the 70% ceiling.

A line on your primary home reaches higher leverage, up to 90% CLTV at 720 or better, and can be larger. The cost is that your home becomes the collateral for a rental purchase. Lendmire’s piece Can a HELOC on Your Home Cover an Investment Property Down Payment? goes deeper on that trade.

Draw structure also varies. Investment lines run only the 5-year interest-only draw followed by a 25-year amortizing repayment. Primary and second homes also have a shorter option, a 3-year draw followed by a 17-year repayment. Tennessee shortens both structures.

The network’s DSCR programs also have structural variety: extended terms, interest-only periods, and ARM options through select lenders. The line and the purchase loan are separate decisions, and each carries its own set of term choices.

Where Do the Rules Break?

These are the cases that surprise investors.

The property is held in an LLC. An LLC, corporation, partnership, or land trust cannot hold title on the line. This is the sharpest difference from a DSCR loan, which can be made to an entity, subject to program terms. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.

The borrowed share is the whole down payment. Financing nearly 100% of the purchase across two loans leaves almost no equity cushion. Some DSCR programs cap this or want unborrowed cash in the deal.

The line is someone else’s. A parent’s or partner’s line is not your funds. Lenders treat that money like a gift or a third-party loan, which most DSCR programs restrict.

The line shrinks before you use it. According to the CFPB’s HELOC explainer, a lender can restrict further draws if the home’s value falls significantly. The same source notes that falling behind on payments can cost you the home. Draw and document the money before you write an offer.

The payment moves. The FTC notes that you pay only on what you borrow and that these lines typically carry variable pricing. Here, at least 75% of the line is drawn up front, so most of the balance carries a floating payment from the start. After the 5-year interest-only draw ends, the payment steps up as repayment begins.

The property is listed. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA. Texas investment properties are eligible as non-homestead transactions, and Texas properties are limited to 10 acres.

The rental passes the ratio but not your budget. Clearing 1.00 on a DSCR file is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capex sit outside the calculation. The line payment sits there too. The new rental has to carry its own mortgage and the line payment, as investors on that same BiggerPockets thread stress.

How Do You Decide?

Match the structure to the investor.

A line on an owned, seasoned rental makes sense when you hold it individually or in a revocable trust, keep modest first-mortgage debt, and have a 700+ score. It also helps when you have a documented plan to repay the line from rent or a later refinance.

A primary-home line fits an investor with a 720+ profile who wants more leverage and accepts putting the home at risk.

Skip the line approach when your credit is under 700 and the rental is the collateral, when the property sits in an LLC, or when the target rental barely clears coverage. In that last case, the added line payment can push total cash flow negative even though the DSCR file looks fine.

Another option is a cash-out refinance of the source property. Cash-out typically tops out near 75% LTV, with about 6 months of seasoning common. It gives you a fixed-balance loan instead of a floating line.

If you are comparing the two paths, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals.
