Can You Use a HELOC for a Vacation Home Down Payment?

The Quick Read: Usually, but only if the lender financing the vacation home accepts borrowed money as down-payment funds and you can carry both loans, because no law stops you from spending drawn HELOC cash, yet each purchase program sets its own source-of-funds rules. A HELOC (home equity line of credit) is a loan secured by a home you already own. Once the cash lands in your account, it is yours to spend. The hard part is the second approval.

• Draw and document the money before you go to contract. Lenders can freeze an open line.
• A vacation home you rent out is generally an investment property, which points to a DSCR loan.
• A DSCR loan checks whether rent covers the property’s own payment. It does not count your HELOC payment.
• Funding 100% of the down payment with a HELOC means financing close to 100% of the purchase across two liens.
• Where the line sits matters: on your primary home, on a rental you already own, or on the new property itself.

Why the Answer Depends on the Purchase Lender

The HELOC and the purchase loan are two separate approvals. The line is underwritten to you. The purchase loan is underwritten to the property, to you, or to both, depending on the program.

Across the wholesale network Lendmire works with, lenders do not treat borrowed down-payment money the same way. Some accept equity-line proceeds as long as the paper trail is clean. Others cap how much of the down payment can be borrowed, or want a minimum from your own funds. A plan that is 100% borrowed can fail on that one rule alone.

That is why the order of operations matters. Ask the purchase lender how it treats borrowed funds before you open anything. Disclose the line on the application. Disclosed and documented funds are routine. Hidden ones are a problem.

Down payment, closing costs, and reserves are also three separate requirements. A lender may let borrowed money cover one and not another. Never assume line proceeds will also count as reserves.

How Much Can You Actually Borrow?

Your usable line is the home’s appraised value times the lender’s allowed percentage, minus what you still owe. That percentage is called CLTV (combined loan-to-value), meaning all loans on the property divided by its value. Federal consumer guidance on home equity lines walks through the same sizing logic and notes that the lender also reviews your ability to repay.

The ceiling depends on which property secures the line, and on your credit profile. Figures below come from select wholesale partners and are subject to lender guidelines and full file review.

Lower credit tiers on a second home step down: 700+ and 680+ reach 85%, 660+ reaches 80%, and 640+ reaches 75%. Lines generally run from $25,000 to $750,000, and the maximum personal debt-to-income ratio is 50%, lower for credit profiles from 600 to 679.

Two structure points matter for a down payment plan. Most lines require at least 75% of the line to be drawn at closing. And the payment on the line can change over time, because pricing floats through both the interest-only draw period and the repayment period. Investment lines run a 5-year draw with a 25-year repayment. Primary and second-home lines offer that structure or a 3-year draw with a 17-year repayment. Home equity lines through Lendmire’s partners are available in 16 states, which is narrower than the 41-market DSCR footprint, including Washington, D.C.

Step by Step: Line First, Contract Second

Open and fund the line before you make an offer. Then follow this sequence.

1. Confirm the purchase lender’s rule. Ask whether borrowed funds are allowed for the down payment, and whether any minimum must come from your own money.

2. Confirm how the vacation home will be used. A second home you occupy and a rental are underwritten differently. Settle this before you borrow.

3. Open the line and draw the cash. An open line is not a funded line, and lenders can stop further draws if your home value falls or your finances change.

4. Move the money into your own account. Keep the closing documents, the draw confirmation, and the bank statements showing the funds arriving.

5. Disclose it. The line will show on your credit report as a new liability. Expect the purchase lender to ask about borrowed funds, and answer plainly.

6. Wire from your account to escrow. A clear trail from the line to your account to escrow is what the underwriter wants to see.

Some investors wait a while between the draw and the purchase so the deposit looks seasoned. Seasoning means the money has sat in your account for a set period. Waiting can help, but it never replaces disclosure. Do not plan around hiding where the money came from.

Vacation Home or Rental? Classification Changes the Loan

If you plan to rent the property, it is generally an investment property, and the financing is usually a DSCR loan. 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.

DSCR stands for debt service coverage ratio. It compares the property’s rent to its monthly payment, which lenders measure as PITIA: principal, interest, taxes, insurance, and association dues. For a full explanation, see Lendmire’s complete DSCR loans guide.

Here is how those files typically look across the network:

• Leverage on a purchase. Most files land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV with roughly a 700+ score.
• Coverage. 1.00 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.
• Credit. A 620 floor exists in parts of the network. Most programs want around 660, and 700+ unlocks the strongest tiers.
• Loan size. Loan amounts go up to $3,000,000 on standard programs, with smaller balances available through select lenders.
• Reserves. These vary by lender, leverage, and loan size. Around 6 months of PITIA is common, and larger loans typically step up.

A vacation property that you will list short-term has its own tier. Purchase leverage tops out at 75% LTV, with a 640+ score and about 12 months of hosting history expected. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Some property types are not offered at all through the network’s DSCR programs: manufactured homes, log homes, and barndominiums. A rustic cabin may fall into that group, so check the construction type early.

What the DSCR Ratio Does Not See

Qualification on a DSCR loan rests primarily on property-level rental income covering the payment, subject to lender guidelines. Your HELOC payment generally sits outside that ratio, which is why investors pair the two. It is also the trap.

Run the picture this way. A vacation condo rents for enough to clear about 1.25x coverage. The ratio looks healthy. But the rent was never asked to cover the line payment, and you are making that payment from your own pocket.

Clearing 1.00 is also not the same as positive cash flow. DSCR counts rent against PITIA only. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.

Stack the pieces and the exposure is clear:

• Near-100% financing. If the line funds the whole down payment, you have financed almost the entire purchase.
• Three obligations. Your primary mortgage, the line, and the new property loan all come due every month.
• Variable payments. Variable-payment plans can change what you owe even if you borrow nothing more.
• Collateral risk. A line on your primary home puts that home behind an investment. Missed payments can cost you the house.
• Scaling limits. Each line draws on the same pool of equity and the same personal approval, so only one or two deals fit at a time for most investors.

Treat the HELOC payment as a real monthly cost. Budget for it, and test whether you could carry it with the vacation home vacant for a stretch.

Which Property Should Secure the Line?

You have three options, and each carries a different risk.

A line on your primary home usually offers the highest leverage, up to 90% CLTV at a 720-or-better profile, but your residence stands behind the vacation purchase. A line on an existing rental puts only that rental at risk, though investment lines are capped at 70% CLTV and $500,000 total. A line on a second home sits between the two.

Title matters too. The property securing the line must be held by you individually or by a revocable living trust. A property already deeded to an LLC cannot secure one, so that file needs a title change or a DSCR cash-out refinance instead. Lendmire has covered the equity-line mechanics in its piece Can You Use a Primary Home HELOC as a Rental Down Payment?, and the wider options in its guide How to Use Home Equity to Fund a Rental or BRRRR Down Payment.

Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.

Key Terms Defined

HELOC: A revolving credit line secured by a home you own, with a draw period followed by a repayment period.

CLTV: Combined loan-to-value, meaning all loans against a property divided by its value.

DSCR: Debt service coverage ratio, which compares a rental’s income to its monthly payment.

PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly housing payment lenders count.

Seasoning: The period funds sit in your account, or a loan stays in place, before a lender treats it as settled.

Reserves: Cash left over after closing that proves you can keep paying if income dips.

Is This Right for You?

This tends to fit when the vacation home will be a rental, the line sits on a property you can afford to carry, and you have reserves beyond the down payment. It also fits when the purchase lender has confirmed that borrowed funds are allowed. The strongest files clear both tests: enough equity and enough rental coverage.

It tends to be a poor fit when the line is your only cash, your reserves are thin, or the rent barely covers the property’s own payment. It is also risky when you plan to hold the property a short time, or when you would struggle to make the line payment while the home sits empty.

Consider alternatives if the fit is weak. Savings, a gift, a smaller purchase, or a larger down payment on a lower-priced property all reduce the stacking problem. A larger down payment also lowers the property’s monthly payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility.
