How to Use an Investment Property HELOC for a Vacation Home Down Payment

The Quick Read: You open a line against a rental you already own, draw cash, and hand that cash to the vacation-home lender as your down payment, but only if that lender accepts borrowed funds and the new home can carry its own payment. On Lendmire’s wholesale network, an investment-property line tops out at 70% CLTV (combined loan-to-value, meaning every loan on the property added together, measured against its value) and $500,000. Your rental’s equity sets the size of the down payment, and the vacation-home lender decides whether that money counts.

• The collateral is your rental. If the draw goes unpaid, the rental is the property at risk, not the vacation home.
• The purchase lender has the final say. Some programs accept borrowed funds for a down payment and closing costs but exclude them from reserves.
• Interest starts on day one. The network’s investment-property line requires at least 75% of the line to be drawn at closing.
• The vacation home must stand on its own. If you plan to rent it, the lender checks whether rent covers its monthly payment.
• Your rental must carry two debts. It has to support its own mortgage and the new line.

Key Terms Defined

HELOC (home equity line of credit): A revolving credit line secured by a property you own. You draw cash against your equity as needed, up to the approved limit.

CLTV (combined loan-to-value): Your first mortgage plus the line, divided by the property’s value. A 70% cap means all debts on the rental together may not exceed 70% of what it is worth.

DSCR (debt service coverage ratio): Monthly rent divided by the monthly payment of principal, interest, taxes, insurance, and any HOA dues (together called PITIA). A ratio of 1.00 means rent equals the payment.

Reserves: Cash a lender wants you to hold after closing, usually counted in months of PITIA. They are a safety cushion, separate from the down payment.

Seasoning: The time money has to sit in your account, or a property has to be owned, before a lender treats it as yours.

Source of funds: The paper trail showing where your down payment came from. For a line draw, that means the line agreement, the draw record, and the bank statement showing the deposit.

What Does a HELOC on a Rental Actually Look Like?

An investment-property line on this network is a standalone line, in first or second lien position, secured by a rental you own. It is not a feature of your mortgage. It is a separate loan with its own approval.

Here are the parameters that matter, all subject to lender guidelines and full file review:

• Leverage: The ceiling is 70% CLTV on an investment property. Credit above 700 buys eligibility, not extra leverage.
• Credit: The minimum is 700 for an investment property.
• Line size: Programs run from $25,000 to $750,000, but an investment-property line is capped at $500,000. Anything larger is for primary residences only.
• Structure: Investment lines use a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. Pricing floats the whole way and never converts to fixed.
• Debt-to-income: The maximum is 50%. The lender reviews your file on the interest-only payment calculated at the full draw.
• Valuation: Because investment lines cap at $500,000, they usually run on an automated valuation with no traditional appraisal. You may still request a full appraisal.
• Title: The rental must be held by you personally or by a revocable living trust.
• Limits: A borrower can hold up to three lines, and anyone with more than 15 financed properties is not eligible.
• Availability: The product is offered only in the 16 states where Lendmire provides full-service lending. That is narrower than its 41-market DSCR footprint.

Eligible collateral includes single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.

How Underwriting Treats the Move, Step by Step

Underwriting happens twice. The line lender approves you and the rental. Later, the vacation-home lender decides what to do with the cash you drew. Neither approval guarantees the other.

1. The line is approved against the rental. The lender measures CLTV: your first mortgage balance plus the new line against the rental’s value. If your existing mortgage uses roughly half the value, the line can use only the gap up to 70%. That gap is your maximum borrowing power, before credit and DTI checks.

2. Credit and DTI come next. You need at least a 700 score, and the 50% DTI test uses the interest-only payment on the maximum draw. That is stricter than it sounds, because the test assumes you use the whole line.

3. You draw the cash. On this structure, at least 75% of the line is drawn at closing. That helps if you need most of it for a down payment. It hurts if you only needed a slice, because you carry interest on the rest.

4. You document the source of funds. Expect the vacation-home lender to ask for the line agreement, proof of the draw, and statements showing the deposit. Some lenders also want the money to sit in your account for a set period before they count it.

5. The vacation-home lender underwrites the new property. The down payment, closing costs, and reserves are three separate tests. A program can accept borrowed money for one and reject them for another.

That last step is where most plans change shape, so it gets its own section.

Who Decides Whether Borrowed Money Counts?

The purchase lender decides, not the line lender. That is the single most misunderstood point in this strategy. A line lender doesn’t care how you spend the cash. The vacation-home lender cares a great deal where your down payment came from.

Bankrate notes that not all lenders allow home equity funds toward a down payment when you also take out a mortgage on the new property. Large retail lenders tend to be the strict ones. One BiggerPockets discussion shows a bank refusing the practice, with a reply explaining that big lenders want a down payment to be cash that builds equity. That reply also notes the practice is common once underwriting requirements are met.

Agency loans are a useful contrast. Fannie Mae’s Selling Guide treats asset-secured borrowed funds as acceptable for a down payment, closing costs, and reserves. DSCR loans are not agency loans, though. Each non-QM program sets its own borrowed-funds rule, so the agency treatment doesn’t carry over.

Across the wholesale network Lendmire works with, the pattern is mixed but workable. Many exclude them from reserves. Some cap the borrowed share. The practical lesson is to pick the purchase program first and confirm its rule before you open the line. Opening the line first and hoping is the most expensive order of operations.

Vacation Home or Rental? The Label Changes the Loan

How you plan to use the home decides which loan applies. If you will live in it part of the year and never rent it, the owner-use second-home route may fit. If you plan to qualify on rental income, you are buying an investment property, and a DSCR loan is the natural tool.

Be honest about this. Lenders classify by use and occupancy, and describing a rental as a second home to get softer terms is occupancy misrepresentation. Market surveys put investment-property down payments at roughly 15% to 25% on conventional-style loans, according to Bankrate. On this network, DSCR purchases most often land at 75%-80% LTV, meaning 20%-25% down. Select high-leverage programs reach 85% LTV on a purchase, meaning 15% down, with roughly a 700-plus score.

If the vacation home will be a short-term rental, programs change. Short-term rental purchases run up to 75% LTV, expect a 640-plus score and about 12 months of hosting history, and start at a 1.00 coverage floor on purchases. A home with no hosting history yet needs a conversation with the lender about how they treat it. 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. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

What the DSCR Side of the Purchase Checks

A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. 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. Lendmire’s complete DSCR loans guide covers the full mechanics.

• 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-plus unlocks the strongest leverage tiers.
• Loan size: Standard loans run up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000 the network generally holds to 30-year fixed structures.
• Reserves: They vary by lender, leverage, loan size, and transaction type. About 6 months of PITIA is common, conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up toward 9 months.
• Structure: The 30-year fixed is the spine. Extended terms, interest-only periods, and ARMs are available through select lenders.
• Entity: A vacation home can be titled in an LLC, subject to lender program eligibility.

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

DSCR compares rent to PITIA only. Clearing 1.00 does not mean the property produces positive cash flow, because repairs, vacancy, management, utilities, and capital expenses sit outside the ratio. DSCR on manufactured homes, log homes, and barndominiums is not offered.

Whether the line payment on your rental enters the vacation-home file’s ratio depends on the program. Ask before you apply. Some purchase lenders review the new property’s income against its own payment only. Others look harder at your total debts.

Add Up Three Payments Before You Draw

The risk in this plan is stacking. You carry your rental’s first mortgage, a floating-price line, and the vacation-home loan at once. Each looks manageable alone.

Run a stress test on the rental first. Say the rental covers its own first mortgage at roughly 1.35x. Add the line’s interest-only payment and that picture can slide toward 1.1x. Add a vacancy and it can fall below 1.00. These ratios are illustrations, not market data. Run your own with real numbers.

Three more risks deserve attention:

• Little cash cushion. If the line funds the entire down payment, none of your own cash goes into the purchase. You carry two separate loans on top of the rental’s first mortgage, with no equity you paid in yourself. One BiggerPockets thread makes the same point about borrowing the whole down payment.
• The line floats and never converts to fixed. The payment can move after you draw.
• The draw period ends. After the 5-year interest-only draw, the line becomes fully amortizing over 25 years, and the payment steps up.

Investors often treat this as a bridge. One BiggerPockets discussion describes a line as a good short-term tool if you can repay it within a year or two, and a poor fit for a long-term down payment. That is sensible. Decide how you will pay it down before you draw it.

Where the General Rule Breaks

Three edge cases catch investors who thought they had a plan.

The rental sits in an LLC. The investment-property line must be held by you personally or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.

The rental is the wrong property type or in the wrong status. Manufactured homes, co-ops, condotels, log homes, and commercial or mixed-use properties are not eligible collateral. In several states, a property listed for sale, or listed within the past 60 days, is ineligible. Derogatory credit history matters as well. A bankruptcy needs 4 years of seasoning from discharge or dismissal, and investment files follow a 7-year and 4-year seasoning path for foreclosure-family events.

You need more than $500,000. An investment-property line caps at $500,000. A larger line is for primary residences only. It requires a 700-or-better credit profile (720 on the longer-runway structure), caps at 75% CLTV, and needs a full appraisal. That is a different product with different collateral, so it changes your risk.

What Are the Alternatives?

The line is not the only way to pull equity out of a rental. Here is how the main options compare:

A DSCR cash-out refinance replaces your first mortgage rather than adding a second loan. On this network it tops out around 75% LTV on a standard-rental cash-out, and a short-term rental cash-out is limited to 70% LTV. About 6 months of seasoning is the common expectation. Our best investment property HELOC program for a vacation home down payment compares these paths in more detail. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

A line on your own home puts your residence at risk, which is a very different decision from risking a rental. Many investors prefer that the collateral match the purpose, but that is a judgment about risk tolerance, not a rule.

Should You Do It?

Here is a quick check to help you decide whether to go, wait, or rethink your plan.

You are likely ready to go if:

• Your rental has enough equity for the line at 70% CLTV or less.
• The rental covers both its own mortgage and the line payment, with room for vacancy.
• Your credit is 700 or higher.
• The vacation-home lender has confirmed in writing that borrowed funds count for the down payment.
• You have a repayment plan for the line.

Wait if the purchase program hasn’t been chosen, or the rental’s coverage only works if it never has a vacant month. Rethink the plan if the line would fund the entire down payment and the vacation home’s coverage barely clears 1.00. At that point, a smaller purchase or a bigger cash cushion usually serves you better.
