Banks That Offer a HELOC to Fund a Second Home Purchase

The Quick Read: A home equity line of credit (HELOC) can fund a second home purchase when you open and draw the line before the purchase loan closes, keep enough equity in the property that secures it, and use a purchase lender that accepts borrowed funds, and which banks offer it depends on your property, credit profile, and leverage. No single bank name settles that. The lender’s rules do.

• On Lendmire’s wholesale network, a second-home line starts at a 640 credit profile. It reaches 90% combined loan-to-value (CLTV, the first mortgage plus the new line as a share of the home’s value) only at 720 or better, up to $500,000.
• An investment-property line tops out at 70% CLTV on this network.
• At least 75% of the line must be drawn when the line closes, which suits a down payment but starts the payment clock early.
• The purchase lender tests the down payment, closing costs, and reserves as separate pots of money.
• If the new property is a pure rental, the purchase loan is usually a DSCR loan, and the line only supplies cash.

Key Terms Defined

Draw period: the stretch of the line’s life when you can pull money out, usually paying interest only.

Repayment period: the later stretch when borrowing stops and the balance amortizes to zero.

Second home: a home you keep for personal use, which lenders price and underwrite differently from a rental.

Investment property: a property bought mainly to rent out, which carries tighter leverage limits on equity lines.

DSCR: the debt service coverage ratio, which compares a property’s monthly rent to its full monthly payment.

PITIA: principal, interest, taxes, insurance, and any association dues, which together make up that full payment.

Vesting: how title is held, whether in your own name, a trust, or an LLC.

Which Kinds of Lenders Offer This, and What to Ask Them

Four kinds of lenders write home equity lines: large retail lenders, credit unions, online lenders, and wholesale lenders reached through a broker. Each sets its own rules on occupancy, property type, and use of funds. Lendmire is a mortgage broker, not a lender. It matches a borrower’s file to a wholesale lender whose program fits, which is why this article names no banks.

Naming banks would mislead you anyway. Policies change, and a bank that welcomes a primary-home line may refuse to write one on a rental. Screen any lender with these questions:

1. Will the line sit on my primary home, a second home, or a rental?

2. Does the line agreement allow the money to buy another property?

3. What is the maximum CLTV for my credit score and occupancy type?

4. How much of the line must be drawn at closing?

5. Is the pricing fixed, or does it float?

6. Will the purchase lender accept these funds as a down payment? Put this one to the purchase lender directly.

Question six deserves extra care. A bank can approve the line and still leave you with a purchase lender that rejects the cash.

Two Different Lines, Two Different Collateral Choices

Most investors use one of two routes. The first draws on a line secured by the home you already live in. SmartAsset notes that your primary home is the collateral in that case, and a missed payment puts that home at risk.

The second draws on a line secured by another property you already own, such as a seasoned second home or a rental you are keeping. That route sits beside the purchase and has its own occupancy limits, covered below.

A line secured by the home you are buying cannot fund that same purchase. The line needs a property you already own. So the cash always comes from equity in something else.

How the Process Works, Step by Step

The sequence matters more than the product. Here is how it runs from start to finish.

1. Open and fund the line first. The line must close and be drawn before you make an offer or lock the purchase loan. A line approved ahead of time also lets you shop with cash in hand.

2. The lender sets your limit. It takes a percentage of the property’s value, then subtracts what you owe. The CFPB’s HELOC explainer describes the line as an open-end credit you can borrow against repeatedly up to that limit. It also warns that you could lose the home if you cannot repay.

3. The lender underwrites you. Expect a credit check, a review of income and debts, and a value check on the property. On this network, lines at or below $500,000 ordinarily use an automated valuation instead of a full appraisal.

4. You draw the cash and document it. The purchase lender will want the line’s closing papers and proof of the draw.

5. You qualify separately for the purchase loan. A second-home mortgage looks at your personal income and debts. A DSCR purchase looks at the property’s rent against its own payment.

6. You carry three obligations. That means your primary mortgage, the line, and the new mortgage, all at once.

The line is not a purchase loan. It supplies cash. You still need a mortgage on the new property unless you buy it outright.

What the Network’s Equity Lines Look Like

Lendmire works with a network of wholesale HELOC lenders, and their guidelines are the ranges below. Every figure is subject to lender guidelines and full file review, and nothing here is a commitment to lend. These are the network’s limits, and they depend on occupancy.

For a second home, the maximum CLTV rises with your credit profile, on lines up to $500,000:

Below 640, a second-home line is not available. On an investment property, the ceiling is 70% CLTV with no higher tier, and the credit minimum is 700. A primary residence line reaches the same 90% ceiling, and only at a credit profile of 720 or better.

The basic structure is a standalone line in first or second lien position, sized from $25,000 to $750,000. A line above $500,000 is for primary residences only. Draws run either three years of interest-only borrowing followed by 17 years of repayment, or five years followed by 25 years. Investment lines use the five-year draw and 25-year repayment structure only. Pricing floats through both periods and never converts to fixed. The maximum debt-to-income ratio is 50%, qualified on the interest-only payment at the full draw.

How the Purchase Lender Treats Borrowed Cash

Purchase lenders sort your cash into three pots: down payment, closing costs, and reserves. Reserves are the months of payments you keep liquid after closing. A lender may accept borrowed funds for the first pot and still insist the reserves be your own money.

Closing costs are a real draw on the line too. Banks.com puts typical mortgage closing costs at 2% to 5% of the loan amount. Plan the draw to cover all three pots, not just the down payment.

Where the General Rule Breaks

The basic rule is “draw first, then buy.” These cases bend or break it.

• A fully borrowed down payment. Some purchase programs cap how much of the down payment can be borrowed. A line that supplies every dollar also stacks close to 100% financing on the new property. That is a lot of leverage.
• LLC ownership. On this network, an equity line must sit on property held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If a rental is already deeded to an LLC, it needs a vesting change first, or a DSCR cash-out refinance fits better.
• Property listed for sale. In several states, a property listed for sale, or listed within the past 60 days, is not eligible.
• Renting out the home that secures the line. Some line agreements restrict rental use. If you plan to move out and rent the home that backs your line, check the agreement first.
• Ineligible property types. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible for these lines. Condos, including non-warrantable ones, single-family homes, 2-4 units, PUDs, and townhomes are.
• Exposure limits. A borrower is limited to three lines, with combined exposure capped at $2,000,000 or $750,000 depending on the program. An investor with more than 15 financed properties is not eligible.
• Availability. Lendmire’s HELOC placements cover 16 full-service states, which is narrower than its DSCR footprint of 41 markets, including Washington, D.C.

Second Home or Rental? Where DSCR Takes Over

If the new property will serve as a rental, a second-home mortgage is the wrong tool. Lenders treat a rental as an investment property, and a DSCR loan is built for that case. 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. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

These are the typical network ranges for that purchase loan, each subject to lender guidelines:

• Leverage: most files land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select high-leverage programs reach 85% LTV with roughly a 700+ score.
• Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
• Credit: a 620 floor exists in parts of the network. Most programs want around 660, and 700+ unlocks the strongest leverage tiers.
• Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).

A DSCR ratio compares rent to the property’s own PITIA. Your line payment is not part of that ratio. Clearing 1.00 also does not mean positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. The line’s payment still comes out of your pocket from the first day. For a closer look at the full program, see Lendmire’s complete DSCR loans guide.

Equity is not the only test. A larger down payment lowers the monthly payment and can lift coverage, but it never erases credit floors, reserve rules, or property eligibility. The strongest files have enough equity and enough rental coverage.

Is It Worth Doing? A Practical Decision

Think about what you are stacking. The line’s pricing floats, and your payment moves with the balance. During the draw period you pay interest only, so you are not building equity on that debt. Then repayment starts and the payment steps up.

The CFPB’s home equity guide says lenders typically want you to keep at least 10% to 20% of your home’s value as equity. Use that as a personal cushion too. A line that drains the cushion on your main residence turns a bad quarter into a risk to your home.

Run three stress tests before you draw. First, can your income carry the primary mortgage, the line, and the new mortgage if the property sits empty for a few months? Second, can you cover a payment increase when the draw period ends? Third, can you still carry every payment if the line’s floating pricing moves against you?

The decision comes down to a few facts:

• You have a lender who accepts borrowed funds, in writing.
• You keep real equity after the draw.
• The new property covers its own payment, or you can cover the gap from other income.
• You have a payoff plan, not just a hope.

If one is missing, a different structure, or a bigger down payment from savings, may serve you better.
