Investment Property HELOC Requirements on a Primary Rental to Buy a Rental Package

The Quick Read: A home equity line on a rental you already own can supply the down payment for your next rentals, but it never buys the package by itself. A separate purchase loan, usually a DSCR loan, does the buying, and the line only changes where your cash comes from. Both approvals have to hold, and the line has to be in place first.

• On an investment property, the network’s line tops out at 70% combined loan-to-value (CLTV), with a 700 credit minimum and a line size of $25,000 to $500,000.
• The rental that secures the line must be held by you or your revocable living trust, not an LLC.
• Your purchase lender decides whether borrowed money counts toward the down payment, so ask before you draw.
• Each new rental still needs its own rent to cover its own payment.
• A line can freeze or shrink, which is a real risk in the middle of a multi-property closing.

Say you own a seasoned duplex, and a small package of rentals comes up for sale. You want the equity in the duplex to fund the down payments. This article walks through how that works, step by step. It covers the structures, the places the plan breaks, and how to decide whether it fits you.

Key Terms Defined

HELOC (home equity line of credit): a revolving credit line secured by a property you own. You borrow what you need, up to a limit, and pay interest on what you use.

CLTV (combined loan-to-value): every loan secured by the property, plus the full line amount, divided by the property’s value.

DSCR (debt service coverage ratio): monthly rent divided by the monthly payment on the property, covering principal, interest, taxes, insurance and any HOA dues.

Seasoning: the waiting period a lender wants after you buy or refinance a property before you borrow against it again.

Blanket loan: one loan secured by several properties at once. It is also called a portfolio or cross-collateralized loan.

Lien position: your lender’s place in line if the property is sold to pay debts. A first lien is paid before a second lien.

What a HELOC Does and Doesn’t Do in a Package Deal

A HELOC is a source of cash, and nothing more. It does not purchase property, and it does not qualify the rentals you buy.

Think of the deal as two separate loans with two separate approvals. The first is the line, secured by your existing rental. The second is the purchase loan, secured by the new rental or rentals. The purchase lender looks at your bank statements, sees where the down payment came from, and decides whether that source is acceptable.

That second decision is where plans stall. Across a network of DSCR lenders, programs differ on whether borrowed funds can cover the down payment, closing costs or reserves. Some accept them. Others want the money to be yours. Get the answer in writing before you draw a dollar.

The market for these lines is also thin. NerdWallet’s explainer on investment property HELOCs says you can get one, but the lender pool is smaller than for primary homes. It adds that you generally can’t borrow as much and that qualification is strict. Many large banks don’t write rental lines at all, which is why investors often work through a broker who sees several lenders.

How Underwriting Treats the Line, Step by Step

Underwriting follows a fixed order. Each step can end the plan, so it helps to know them in sequence.

1. The source rental has to qualify. The network’s investment line takes single-family homes, 2-4 unit properties, PUDs, townhomes and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural properties are not offered. The property should be a non-owner-occupied rental with a lease in place.

2. Title and seasoning come next. Title must sit with you personally or in a revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title on the line. A rental you recently bought or refinanced usually has to season first.

3. Lien position follows what is recorded. A first lien exists only when the rental has no mortgage. Nearly paid off does not count. Otherwise the line sits as a second lien behind your existing first mortgage.

4. The equity test is CLTV. The lender adds your first mortgage and the full line commitment, not just the drawn balance. On an investment property, that total cannot exceed 70% of value. Your credit score doesn’t change this. A 720 score buys no more leverage than a 700 on investment collateral.

5. Your personal profile is tested. A standard investment line is underwritten on your credit, your debt-to-income ratio (DTI) and your equity, not on the rent. The minimum credit score is 700. DTI tops out at 50%, and the lender calculates it on the interest-only payment at the maximum draw. Self-employed borrowers can document income through bank statements under the applicable program, subject to lender guidelines.

6. Valuation is usually automated. Because an investment line caps at $500,000, it normally runs on an automated valuation model without a traditional appraisal. A full appraisal only becomes mandatory on lines above $500,000, which are reserved for primary residences.

7. You draw and document the cash. At least 75% of the line is drawn at closing. That matters for planning, because you pay interest on money that may sit in your account until the purchase closes. The draw period runs five years, followed by a 25-year repayment period. The payment floats with the market and never converts to a fixed payment.

After that, your DSCR purchase loan is qualified separately. Each new rental is judged on its own rent against its own payment. The line payment generally sits outside that ratio, but it is still a real obligation your portfolio has to carry.

How Do the Line and the Purchase Loan Fit Together?

The line lowers the cash you need at closing. It doesn’t change the rules of the purchase loan. On a DSCR purchase, most files across the network land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV (15% down) with a score of roughly 700 or better. Credit floors vary: a 620 floor exists in parts of the network, most programs want around 660, and 700+ opens the strongest tiers. Loans reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.

Coverage is where many first-timers get surprised. A 1.00 ratio 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 vary by lender, leverage, loan size and transaction type. They commonly run around six months of PITIA, meaning principal, interest, taxes, insurance and association dues.

Clearing 1.00 is not the same as making money. DSCR compares rent to the monthly payment only. Repairs, vacancy, management, utilities and capex all sit outside it. For the full picture of how these loans work, see Lendmire’s complete DSCR loans guide.

Three Ways to Structure the Package

You have more than one way to fund a package, and each one puts risk in a different place.

A line plus separate DSCR purchases is the most flexible. You can close the rentals one at a time, and each loan stands alone. A blanket loan puts several properties under one note. It suits a uniform, seasoned pool you plan to hold, because selling one property later usually means negotiating a release.

The cash-first route avoids borrowed-down-payment questions entirely. You buy with your own funds, then pull equity out afterward. On a standard rental, DSCR cash-out refinances top out around 75% LTV, with about six months of seasoning as the common expectation. Short-term rentals run lower, with cash-out at 70%. Note that cash-out replaces your old first lien rather than adding to it. It also suits LLC-held rentals, since the line can’t be written on those. DSCR loans to LLCs depend on program guidelines. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

A Worked Example: Funding Three Down Payments

Run the numbers on an investor who owns one seasoned rental with a first mortgage at 55% of its value. The investment line’s CLTV ceiling is 70%. That leaves 15% of the property’s value for the line, and the full commitment counts against it, drawn or not.

The investor wants to buy three rentals. Each purchase goes through a DSCR loan at 75% LTV, so the line has to fund the other 25% on each, plus closing costs. If the line covers all of it, total borrowing across the old and new properties approaches the full purchase price. That is the leverage stack, and it leaves almost no equity cushion in the new deals. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Now check the coverage. Assume a new rental clears roughly 1.2x on its own rent against its own payment. That is a modeled assumption, not a market figure. Trim the rent by 10% to simulate a vacancy or a rent cut, and the ratio falls to about 1.08x. It still clears a 1.00 floor, but the margin is thin.

The test is not finished, though. The line payment is separate and sits outside the DSCR ratio, so the portfolio still has to cover it. A package with a 1.2x ratio on paper can run short of real cash once the line payment, repairs and vacancy are added. Test the package with the rent cut, the line fully drawn and an empty month or two. If the plan only works when everything goes right, it doesn’t work.

Where the Rule Breaks

Several situations break the general pattern, and it is worth checking them before you commit.

A borrowed down payment can be refused. This is the most common wall. The line closes, you draw the cash, and then the purchase lender won’t count it. Ask each purchase lender in writing first.

An LLC-titled rental can’t take the line. The fix is a vesting change into your name or trust, or a DSCR cash-out refinance instead.

One property’s equity can’t back a line on another. A HELOC is secured by one property, and lines aren’t cross-collateralized. Only a blanket loan pools properties.

The chain slows down. A rental you buy with line proceeds has to season before it can carry a line of its own.

First-time investors have no seasoned rental to draw on. Without that equity, the plan has no starting point.

Count limits apply. The network allows a borrower three lines, and combined exposure is capped. An owner with more than 15 financed properties is not eligible. If you carry a bankruptcy, it needs four years of seasoning from discharge or dismissal. Foreclosure-family events season on a seven-year or four-year path, depending on the event.

Availability is narrower than DSCR. DSCR programs run across 40 states plus Washington, D.C., which is 41 markets. The line is offered only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA.

A line on your own home is a different tool. On a primary residence, the ceiling reaches 90% CLTV, but only at a 720 or better credit profile. Lines above $500,000 are available only on a primary residence. The tradeoff is that your home becomes collateral. Lendmire’s walkthrough of using home equity to buy a rental covers that route.

Can the Lender Freeze the Line Mid-Closing?

Yes, and that risk is easy to overlook. An undrawn line is not money in your account. The CFPB explains that a significant drop in value, or the lender’s belief that you can’t repay after a financial change, can stop further draws. Available credit may then be less than you expected.

The FTC lists the same triggers. It also says a lender may not close the account or demand the balance early if you pay as agreed. On this network, the answer to freeze risk is simple: draw at least 75% at closing, so most of the money is already in your hands.

Also plan the exit. The interest-only draw period ends and a fully amortizing repayment begins, so the payment can step up sharply. Common exits include a DSCR cash-out refinance on the properties you acquired. Check whether the DSCR loans carry prepayment penalties, since those can complicate that exit.

Should You Use It?

The line is a good fit when these conditions line up:

• You hold a seasoned, personally titled rental with real equity under the 70% CLTV ceiling.
• Your credit sits at 700 or better and your DTI clears 50% on the full line payment.
• Your purchase lender has confirmed in writing that it accepts borrowed funds.
• The new rentals clear the coverage test with room to spare, even after a rent cut.

Skip it, or choose another route, in these cases:

• Your rentals sit in LLCs and you don’t want to re-title them.
• The package needs the line to cover close to 100% of the cost.
• Your lender won’t accept borrowed funds.
• You are a first-time investor with no seasoned rental.

A DSCR cash-out suits LLC-held, staggered portfolios. A blanket loan suits uniform pools you plan to hold. A line suits smaller, flexible needs on personal-title rentals with strong credit.

Next Steps

Start by writing down your equity, your first mortgage and the CLTV left under 70%. Then ask your purchase lender, in writing, whether borrowed funds count. Finally, model each new rental’s coverage with the rent trimmed.
