Best HELOC Program to Purchase a Second Home Without Selling Your Current One

The Quick Read: No single HELOC program wins for every buyer, because this plan runs on two separate loans: a home equity line on the home you keep, and a purchase loan on the new property, each with its own approval test. The setup that works best is a line opened and funded before you go under contract, paired with a purchase lender that accepts documented borrowed funds for the down payment.

• Two approvals, not one. The line lender looks at your equity, credit, and debt load. The purchase lender decides whether borrowed money counts as down payment.
• Ceilings depend on occupancy. Across Lendmire’s wholesale network, a primary-residence line reaches 90% combined loan-to-value (CLTV) only at a 720-or-better credit profile. An investment-property line stops at 70%.
• Reserves are the usual snag. Many purchase programs accept borrowed funds for the down payment and closing costs, but commonly want reserves from your own seasoned accounts.

How Does a HELOC Fund a Purchase Without a Sale?

You borrow against the equity in your current home, move the cash into your own account, and use it for the down payment on the new property. Your existing mortgage stays in place. You keep both homes and carry three obligations: the first mortgage, the line, and the new loan.

Here is the catch most people miss. The line does not care what you spend it on. The purchase lender does. That is why the order of operations matters more than the choice of line.

If the new property is a rental, the purchase loan is usually a DSCR loan. DSCR means debt service coverage ratio: the property’s monthly rent compared with its monthly payment of principal, interest, taxes, insurance, and any HOA dues (together, PITIA). The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Our complete DSCR loans guide covers that product in full.

One distinction up front. If you plan to use the new property as a true second home for personal stays, DSCR is the wrong tool. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.

Key Terms Defined

• HELOC: A home equity line of credit, a revolving credit line secured by your home that you draw on as needed.
• Equity: The home’s value minus what you still owe on the mortgage.
• CLTV: Combined loan-to-value, meaning your first mortgage plus the new line, divided by the home’s value.
• Draw period: The stretch when you can borrow from the line, often paying interest only.
• Repayment period: The stretch after the draw ends, when you pay down principal and interest on a set schedule.
• Source of funds: The paper trail showing where your down payment came from.
• Reserves: Liquid money left over after closing, usually counted in months of PITIA.
• Seasoning: How long funds have sat in your account before a lender counts them as yours.

How Does Underwriting Treat Each Loan, Step by Step?

Each loan is judged on its own terms, in this order.

1. Open the line on the home you are keeping. The line lender reviews your credit, your debt-to-income ratio (DTI), and the equity in the home. On the network’s lines of $500,000 or less, valuation is ordinarily automated with no traditional appraisal, though a higher CLTV can require a secondary valuation.

2. Ask the purchase lender about borrowed funds before you draw. This is the step people skip. Some lenders accept borrowed money secured by an asset. Others want part of the down payment unborrowed. Find out first.

3. Draw and document. Move the cash to your own account. Keep the draw record, statements, and a clean paper trail. Many lenders also want funds to sit a while, so ask what seasoning they expect.

4. Qualify the rental on its own rent. The DSCR test compares the property’s rent with the new loan’s PITIA, along with credit, leverage, and reserves. The line payment is not part of that property-level ratio.

5. Cover three separate pots. The down payment, closing costs, and reserves are each tracked on their own.

6. Carry three payments. Your first mortgage, the line, and the new loan all come due, and only the rental income stands behind the last one.

Opening the line is a separate approval from the purchase. A yes on one says nothing about the other.

What Does the HELOC Side Look Like in Lendmire’s Network?

Lendmire is a mortgage broker, not a lender. It places lines through select wholesale partners, and the right program depends on your property, credit profile, and how much combined leverage you need. Every figure below is subject to lender guidelines and full file review.

Ceilings are tiered by occupancy:

On a second-home line, the tiers step down with credit: 85% at 680 or 700, 80% at 660, and 75% at 640. The minimum credit score is 640 on a second home and 700 on an investment property. Primary-residence lines start from a 600 program floor.

Other mechanics that shape the plan:

• Line size: $25,000 to $750,000. A line above $500,000 is primary-residence only and caps at 75% CLTV. It needs a full appraisal and a credit profile of 700 or better (720 on the program built for a longer runway).
• 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 use the 5-year draw only.
• Draw at closing: At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to fixed.
• DTI: 50% maximum, or 45% for credit profiles from 600 to 679. A ratio above 45% requires a 680 minimum. The line is qualified on the interest-only payment at the maximum draw.
• Limits per borrower: Up to three lines, and no more than 15 financed properties.

The 75% draw requirement is easy to overlook. You are not borrowing a small slice and leaving the rest idle. Most of the line is live, and interest-bearing, from day one.

For the broader mechanics of an open-end line, the CFPB’s HELOC explainer describes the draw and repayment periods. It also warns that falling behind could cost you the home that secures the line.

How Do DSCR Lenders Treat Borrowed Down Payment Funds?

Treatment varies by program, and this is where a broker earns its keep. Across our wholesale network, many DSCR programs accept documented, secured borrowed funds for the down payment and closing costs. A few cap the borrowed share. The strictest overlays want part of the down payment unborrowed, so a fully borrowed down payment can fail on that point alone.

Reserves are different. Borrowed funds are commonly excluded from reserves, so those come from your own accounts. Reserves vary by lender, leverage, loan size, and transaction type. Around six months of PITIA is common. Conservative files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about nine months.

On the purchase itself, most files land at 75% to 80% LTV, which means 20% to 25% down. Select high-leverage programs reach 85% LTV, or 15% down, with roughly a 700-plus score. Credit floors run from 620 in parts of the network to around 660 on most programs, and 700 or better unlocks the strongest tiers. Standard loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.

Coverage works the same way. A 1.00 ratio is where many select programs start, not a universal standard. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.

A bigger down payment lowers the monthly payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.

Where Does the General Rule Break?

Several situations change the answer.

The line is on an investment property instead. An investment-property line caps at 70% CLTV and uses the 5-year draw only. It also requires a 700 credit profile. If you want to pull equity from a rental to buy the next one, our piece Best Investment Property HELOC Program to Pull Cash From a Rental Without Selling It walks through that route.

The property sits in an LLC. A line must be held by you personally or by a revocable living trust. LLCs, corporations, and land trusts cannot hold title. That is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.

The home is not eligible collateral. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. For the purchase side, DSCR financing is not offered on manufactured homes, log homes, or barndominiums.

You are self-employed. If your income documentation is non-standard, our article on a bank statement HELOC to purchase a second home covers qualifying on documented income under the applicable program.

You plan to sell the home that secures the line. The CFPB’s HELOC booklet says you generally must pay the line off in full when you sell. It also says a lender can reduce the line if your home’s value drops, and that renting your home out may be prohibited under the line’s terms. The “without selling” plan only holds while you keep the home.

Credit history is damaged. A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure history splits by program: one seasons it for seven years, and the other declines it regardless of age.

Availability is narrower. Equity lines run in a narrower set of 16 states than the 41-market DSCR footprint.

What Does a Worked Example Look Like?

Run the numbers in percentages only. A calculator can convert them to dollars for your situation.

Say your primary home carries a first mortgage equal to 50% of its value. You have a 720-plus credit profile and qualify at the 90% ceiling. In theory, the line could reach up to 40% of the home’s value. Line size limits, DTI, and the 75% draw rule then shape what you actually take.

Now say you target a rental purchase at 75% LTV, which means 25% down. You need that 25% plus closing costs plus reserves. If the line covers the down payment and closing costs, reserves must still come from your own funds. A purchase at 80% LTV lowers the cash you need to bring but typically asks for stronger coverage or credit.

Then check the rental on its own. If rent clears roughly 1.2x its PITIA, the DSCR test looks healthy. That says nothing about the line payment. Clearing 1.00 is also not positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.

Honest take: the file can pass underwriting and still be a stretch. A vacancy, or a jump in the line’s variable pricing, puts pressure on the home that secures it. If a thin 1.00 ratio is the only thing holding the plan together, the margin is too small.

What Do You Need to Do Before You Make an Offer?

Work in this order:

1. Confirm your CLTV room, credit profile, and DTI before shopping for a property.

2. Choose between interest-only draw structures based on how long you need before the rental stabilizes.

3. Ask the purchase lender, through your broker, whether borrowed funds count and at what share.

4. Plan reserves from your own accounts.

5. Open and draw the line before you go under contract, so the paper trail is already clean.

6. Plan the exit. When the draw period ends, payments step up to a repayment schedule. Decide now whether rental income, a later refinance, or paydown from savings covers it.
