Using a HELOC Loan to Buy Investment Property Without Selling

The Quick Read: A home equity line supplies the cash for your down payment, and a separate purchase loan, usually a DSCR loan, closes the rental itself, so you keep your current home while the new property is judged on its own rent coverage. The line has to be open and funded before you go under contract. The purchase lender then decides whether borrowed money counts toward the down payment. Your home stays in place, but it also stays at risk.

Key takeaways

• A HELOC does not buy the property. It funds the down payment, closing costs, or reserves, and a second loan completes the purchase.
• Two separate underwritings happen. The line lender reviews you and your equity. The DSCR lender reviews the rental’s income against its payment.
• Across the wholesale network Lendmire works with, an investment-property line is capped at 70% CLTV and $500,000.
• Clearing a coverage ratio of 1.00 is not the same as positive cash flow. The line payment sits on top of the rental’s real expenses.
• Programs treat borrowed down payments differently, so confirm the purchase lender’s position before opening the line.

How Do a HELOC and a DSCR Loan Split the Job?

A HELOC is a revolving credit line secured by property you already own, and a DSCR loan is a purchase mortgage secured by the property you are buying. The line gives you cash. The DSCR loan turns that cash, plus the lender’s money, into a closed purchase.

Think of it as two tools with different jobs. The line answers the question of where your down payment comes from. The DSCR loan answers whether the new rental can carry its own payment. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose loans, they are reviewed differently from a standard owner-occupied mortgage.

Most purchase files in the network land at 75%-80% LTV, which means 20%-25% down. Select high-leverage programs reach 85% LTV, or 15% down, usually with a score near 700 or better. Even at those levels, the down payment is a large amount of cash to come up with. A line is how many owners cover that gap without selling a home that is paying down or holding a low-cost first mortgage.

Anyone new to the loan side can start with Lendmire’s complete DSCR loans guide, which covers how the ratio and the program tiers work.

Step by Step: How Underwriting Actually Treats the Line

Underwriting runs in a fixed order, and getting the order wrong is the most common way a good plan stalls. Here is the sequence.

1. Ask the purchase lender first. Before you apply for the line, confirm that the DSCR program accepts documented borrowed funds for the down payment. Programs differ, and this answer shapes everything else.

2. Open the line before you write an offer. You cannot open a HELOC on a property you have not bought yet. The line comes from something you already own, so it should be open, funded, and showing on your credit report before you go under contract.

3. The line lender reviews you. It looks at credit, existing liens, equity, and debt. A line is sized from the home’s value, the combined loan-to-value cap, and what you owe.

4. Move the draw into your own account and document it. The purchase lender typically wants the line’s closing documents, the draw confirmation, statements showing the cash landing, and proof that funds cover the down payment, closing costs, and reserves.

5. The DSCR program reviews the rental. It divides monthly rent by the new property’s PITIA, which is principal, interest, taxes, insurance, and any HOA dues. Credit, leverage, and reserves are reviewed alongside that ratio.

6. The line payment generally sits outside the ratio. The coverage test looks at the new property’s payment, not your other debts. That is a real difference from a conventional loan, where the line payment would land in your debt-to-income calculation.

One point deserves emphasis. Large deposits get traced. Lenders expect to see where money came from, and a line draw that is disclosed and documented is routine. Trying to blur the source is the wrong approach and tends to create problems.

Key Terms Defined

HELOC: A revolving line of credit secured by property you own, with a draw period when you can borrow and a repayment period afterward.

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

PITIA: The monthly principal, interest, taxes, insurance, and association dues on a property.

DSCR (debt service coverage ratio): Monthly rent divided by the property’s PITIA, used to judge whether the rental covers its own payment.

Seasoning: The length of time funds or a loan have been in place before a lender will count them.

Reserves: Liquid cash a lender wants left after closing, often measured in months of PITIA.

Two Structures: A Line on Your Home or on a Rental

You can borrow against your own residence or against a rental you already own, and the terms are quite different. The ceiling depends on occupancy, so never apply one tier to the other.

A few details sit behind that table. Above $500,000, a line is available on a primary residence only, needs a credit profile of 700 or better (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal. On an investment line, 720 and 700 both reach the same 70% CLTV, so a score above 700 buys eligibility rather than extra leverage. Because investment lines stop at $500,000, they usually run on an automated valuation instead of a traditional appraisal.

The primary-residence line also comes in two draw structures. One has a 3-year interest-only draw followed by a 17-year repayment. The other has a 5-year draw followed by a 25-year repayment. A quoted figure always belongs to its own structure, and the two should not be mixed. On this network, at least 75% of the line is drawn at closing, and pricing floats through both periods without converting to fixed.

Lendmire’s home equity line placements run in 16 full-service states, which is narrower than its 41-market DSCR footprint, including Washington, D.C. Check availability early if the line is central to your plan.

Where the General Rule Breaks

Every rule here has an edge, and these are the ones that surprise investors most. Each one can change a plan that looked sound on paper.

Programs split on borrowed funds. Across the network, lenders fall into three camps. Some accept documented line proceeds as the down payment. Some cap the borrowed share. Some require a slice of unborrowed, seasoned cash. A plan that is 100% borrowed can fail on that point alone. Saying borrowed down payments are always banned or always fine is wrong either way.

Down payment and reserves are separate pots. Borrowed money may count toward one and not the other. Typical reserves run around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months.

An LLC cannot hold the line. Investment and residence lines must be titled in an individual’s name or an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If a rental is already deeded to an LLC, you need a vesting change or a DSCR cash-out instead, subject to lender program eligibility.

Combined leverage can approach 100%. If a line covers the entire down payment, you carry two liens on two properties and total borrowing nears the full purchase price. That is a legitimate structure for some investors, but it leaves almost no cushion.

The line can change under you. Lenders can freeze or reduce a line, which is why it should be open and funded before you commit to a contract. Under the Consumer Financial Protection Bureau’s HELOC overview, a draw period gives way to a repayment period, and payments can rise sharply when that shift happens. In some cases the whole balance becomes due at once.

Payments can change even when you borrow nothing more. The agency’s HELOC brochure notes that a variable-rate line can raise your payment without any new draw. It also marks the home as at risk if the line is not repaid.

Some properties never qualify. Manufactured homes, co-ops, condotels, log homes, and commercial or agricultural zoning are not eligible for the line. On the DSCR side, manufactured homes, log homes, and barndominiums are not offered in the network.

Ownership counts have limits. A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible. Large portfolio investors often outgrow the line approach for that reason.

Does the Rental Still Cash Flow After Both Payments?

This is the question the DSCR ratio does not answer. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.

A property can clear 1.00 and still lose money every month once those costs and your line payment are counted. A coverage ratio near 1.00 leaves a thin buffer. A ratio around 1.20 or higher leaves room for the line payment and ordinary surprises. A rental that clears 1.00 only barely is a weak choice for a borrower who also carries the line.

On the leverage side, a larger down payment lowers the monthly payment and can lift the ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests, with enough equity and enough rental coverage.

A few program ranges help set expectations. A coverage ratio of 1.00 is where select programs start, and stronger ratios open better pricing and leverage. Coverage below 1.00 is a separate path, available through select lenders in the network, with leverage and terms adjusted. Credit floors vary: 620 exists in parts of the network, most programs want about 660, and 700 or better unlocks the strongest leverage tiers. Standard loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders, and above $2,500,000 the network generally holds to 30-year fixed structures. All of this is subject to lender guidelines and full file review.

Keep the Home or Sell It? How the Decision Looks in Practice

The case for borrowing instead of selling is simple. You keep the property and any low-cost first mortgage you already have, and you avoid a taxable sale. The case against is just as simple. You add a second payment, you put your home behind a variable-cost line, and you stack leverage across two properties.

A common plan is to use the line as short-term capital, stabilize the rental, and then refinance or pay the line down. That is an illustration, not a program rule. It works best when the investor already knows the repayment path before the first draw.

A practical stress test helps. Ask what happens if the rent falls, the unit sits vacant for a stretch, the line payment rises, and the draw period ends, all at once. If the plan survives that combination, it is sturdy. If it only works when everything goes right, it needs more equity, more reserves, or a different property.
