The Quick Read: The best program is the one that fits your equity, your credit, and the rules of the lender buying the vacation home. A line of credit on a rental you already own can fund the down payment, but the purchase lender decides whether those borrowed funds count. On this network, an investment-property line tops out at 70% combined loan-to-value (CLTV), with a 700 minimum credit score and a $500,000 maximum line, subject to lender guidelines.
- An investment-property line and the vacation-home purchase are two separate loans with two separate approvals.
- The line is underwritten to you. A rental-based investor loan on the vacation home is underwritten to the property’s rent.
- Borrowed money is commonly accepted for the down payment and closing costs with documentation, but it is generally excluded from reserves.
- Clearing the rent-coverage test is not the same as positive cash flow, because the line payment sits outside that math.
- If the vacation home will be mostly personal use, a different loan lane applies, and calling it a rental to get this one is a misrepresentation.
What Are You Actually Borrowing Against?
You are borrowing against a property you already own, and which property you pick changes the risk, the ceiling, and the paperwork. A home equity line of credit (HELOC) is a revolving credit line secured by a property. For this goal, the collateral is usually a rental you own or your primary home.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
The Consumer Financial Protection Bureau describes a HELOC as an open-end line. You can borrow, repay, and borrow again up to a limit during a draw period. Then a repayment period begins. Miss payments and the lender can go after the property that secures the line.
That last point drives the choice of collateral. Put the line on a rental and the rental is at risk. Put it on your primary home and your home is at risk. Neither is free. Many investors prefer to risk the rental, because a failed vacation-home deal then does not threaten the roof over their family.
| Factor | Line on a rental | Line on a primary home |
|---|---|---|
| Network CLTV ceiling | 70% | Up to 90%, only at 720+ |
| Minimum credit | 700 | Varies by tier |
| Maximum line | $500,000 | Up to $750,000 |
| Collateral at risk | The rental | Your home |
Market surveys report that homeowners typically need about 15% to 20% equity to qualify for a HELOC. That is a market-wide figure, not a program term. On this network, the investment-property line is held to 70% CLTV, so you need meaningfully more equity in the rental than the market-wide headline suggests.
Which Loan Lane Is the Vacation Home In?
The vacation home sits in the investor lane only if you plan to rent it. A rental-based investor loan is built for non-owner-occupied properties and is judged mainly on the property’s rent. A second-home loan is a different product with use restrictions, and it is outside what this article covers.
Occupancy is not a gray area to negotiate. If you and your family will use the place most of the year, tell the lender that. Calling a personal getaway a rental to get a different loan type is a misrepresentation, not a workaround.
Part-time use is where people get tangled. The IRS draws its own line, and under IRS Publication 527 a dwelling counts as a home when personal use exceeds 14 days and more than 10% of the days it is rented. Loan programs set their own occupancy rules too, so the tax test and the lender test are separate questions. Ask the purchase lender how it treats owner stays before you write an offer.
If the home will be a true short-term rental, the leverage math is different. On a short-term rental purchase, leverage tops out at 75% LTV. 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. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
How Does It Work, Step by Step?
The sequence matters more than any single feature. Here is the order that keeps the file clean.
1. Size and open the line first. The line is sized off the collateral’s CLTV and your credit profile. On an investment property, 720 and 700 both reach 70% CLTV, so a score above 700 buys eligibility rather than extra leverage. Seven hundred is a hard floor with no tier beneath it.
2. Understand the valuation. An investment line caps at $500,000, and full appraisals begin only above that. So these lines run on an automated valuation and commonly close with no traditional appraisal, though you can request a full one.
3. Disclose the line to the purchase lender before underwriting. Tell the lender on the vacation home that the down payment is borrowed. Surprises late in a file cause the worst delays.
4. Draw the funds and keep the paper trail. Underwriters want the money sourced, seasoned, and documented. Expect to provide the line’s closing documents and the draw confirmation.
5. Apply for the purchase loan as its own file. The line does not close together with the purchase. You draw, then the vacation-home loan is a separate application with its own approval.
6. Close the purchase with the funds clearly traced. Down payment, closing costs, and reserves are three separate buckets. A program may accept borrowed money for one and not the others.
One structural detail changes how much to borrow. On this network, at least 75% of the line is drawn at closing, and the line’s pricing floats and never converts to fixed. So do not open a line far larger than you need. You will carry most of it from day one.
How Does the Purchase Lender Treat Borrowed Money?
It depends on the program, and that is the honest answer. Across the wholesale network, many programs accept borrowed money for the down payment and closing costs. A few cap the borrowed share. The strictest overlays want part of the down payment to be unborrowed cash.
Large retail lenders often resist borrowed down payments. Their reasoning is that a down payment should be your own cash building real equity. A down payment that is entirely borrowed can fail on that basis alone, even if the borrower is otherwise strong.
Reserves are the second trap. Reserves are the months of payments you must hold in the bank after closing. Borrowed funds are commonly accepted for the down payment or closing costs with documentation, but they are excluded from reserves. Reserve requirements vary by lender, leverage, loan size, and transaction type. About 6 months of principal, interest, taxes, insurance, and HOA dues (PITIA) is common. Conservative files at modest leverage under $1,500,000 can see reserves waived, while larger loans typically step up to about 9 months.
Here is the practical point. If your savings are thin, borrowing the down payment and then having nothing left for reserves can sink the file. Keep unborrowed cash for the reserve bucket.
Does the Line Payment Count in the Rent-Coverage Ratio?
On a typical rental-based investor file, no. The debt service coverage ratio (DSCR) divides monthly rent by PITIA. The line payment generally sits outside that ratio.
That is useful for qualifying and dangerous for living. Passing coverage is not positive cash flow. The ratio compares rent to the property’s payment and nothing else. Repairs, vacancy, management, utilities, and capital expenses sit outside it. And your line payment sits outside it too, but you still pay it.
Programs that qualify you on debt-to-income do count the line payment, so check this per program. On the line itself, DTI is capped at 50%, with 45% for credit profiles from 600 to 679. The line is qualified on the interest-only payment calculated on the maximum draw, so a bigger line makes the line’s own approval harder.
For the vacation home, 1.00 coverage is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
What Does a Worked Example Look Like?
Run the numbers on a modeled investor. These inputs are assumptions, not market data. Say you own a rental with plenty of equity, and you want a vacation condo that you will rent out. Rent covers the condo’s full payment at roughly 1.05x with 20% down. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Now compare two choices. In the first, you put 20% down. In the second, you stretch the line to put 25% down. A bigger down payment shrinks the purchase loan and can lift the ratio, whether the cash is borrowed or not. In this model, coverage might move toward the low 1.1x range. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Here is the catch. The ratio improved, but your total monthly obligations did not shrink. You added a line payment on the rental. That payment is not in the ratio, so the file looks better than your real cash flow.
Stress-test it before you commit. The investment line runs a 5-year interest-only draw followed by a 25-year fully amortizing repayment. The payment steps up when repayment begins. Because pricing floats, it can also move during the draw. Ask yourself whether the vacation-home rent still carries both loans if occupancy sags for a season.
A bigger down payment never erases other rules. Leverage caps, credit floors, reserve requirements, and property eligibility all still apply. The strongest files clear both tests: enough equity and enough rental coverage. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
What Makes the Best Investment Property HELOC Program for a Vacation Home Down Payment?
The best program for your situation matches three things: the collateral, the purchase lender, and your cash flow. No single program wins for everyone. A broker who shops multiple wholesale lenders can match your scenario to the program that fits.
Here is what to compare.
- Collateral eligibility. The title must be held by you as an individual, or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines.
- Leverage ceiling. For an investment property, 70% CLTV is the ceiling. The 90% figure exists only on primary-residence and second-home lines at 720 or better.
- Line size. An investment line runs up to $500,000. A line above that is primary-residence only, requires 700 or better (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal.
- Draw structure. Primary and second-home lines offer a 3-year draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. Investment lines run the 5-year draw only. The longer-runway program is the one built around the 5-year draw and 25-year repayment structure.
- Exposure limits. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible.
- Purchase-lender fit. Does the DSCR program accept borrowed funds, and how much can be borrowed?
In files like this, the wrong question is usually which line is more affordable. The right question is which purchase program will accept the funds. Settle that first, and the line almost picks itself.
Where Do the General Rules Break?
Several edge cases catch investors off guard.
The rental is held in an LLC. An LLC cannot hold title on the line. If your rental is already deeded to an LLC, you need a vesting change or a DSCR cash-out refinance instead. The vacation-home purchase itself can sometimes close in an LLC, subject to lender program eligibility.
The vacation home is a log cabin. Mountain cabins are a popular vacation purchase, but log homes are not offered through the network’s DSCR programs. Manufactured homes (single- and double-wide) and barndominiums are not offered either. Condotels are not eligible on the line, and neither are co-ops, commercial, mixed-use, or agricultural-zoned properties.
The collateral is listed for sale. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA. Do not list a rental and borrow against it at the same time.
You sell the collateral. When you sell a property that secures a line, the line generally must be paid off. Plan the exit before you borrow.
You live in a state we cannot reach. Investment and home equity lines through Lendmire are offered only in 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. That is narrower than the DSCR footprint.
What Are the Alternatives?
A line is one option among several. The right one depends on how much cash you need and how you want to repay it.
| Option | Structure | Main tradeoff |
|---|---|---|
| Investment-property line | Revolving, floating | Payment outside DSCR |
| Primary-home line | Revolving, floating | Home is at risk |
| DSCR cash-out refinance | Lump sum on rental | Replaces existing loan |
| Higher-leverage purchase | 85% LTV, ~700+ | Lower down payment |
A DSCR cash-out refinance on a standard rental tops out around 75% LTV, with about 6 months of seasoning as the common expectation. It delivers a lump sum, not a revolving line, so it fits when you know the exact amount you need. Read the complete DSCR loans guide for how those files are structured. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Another option is to reduce how much cash you need. Select high-leverage purchase programs reach 85% LTV (15% down) with roughly a 700+ score. Most purchase files land at 75% to 80% LTV. Needing less down can matter more than finding a better way to borrow it. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Who Should Skip This?
Skip this strategy in a few clear situations.
- Your rental barely carries itself. Adding a line payment to a thin rental makes the whole portfolio fragile.
- You have no unborrowed cash. Without reserves, borrowed funds cannot save the file.
- The vacation home is mainly for your own use. The investor lane is the wrong one, and forcing it creates a misrepresentation problem.
- You cannot absorb a payment step-up. The line is floating, and the payment grows when the draw period ends.
- The rental is in an LLC and you do not want to restructure. The line will not work without a vesting change.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.

Frequently Asked Questions
Can I use a line on a rental to buy a vacation home?
Often yes, if the purchase lender accepts borrowed funds. The line is one loan and the purchase is another. On this network, an investment-property line runs up to 70% CLTV at a 700 minimum credit score, up to $500,000. The purchase lender still decides whether the borrowed money counts toward the down payment.
Will the line payment hurt my DSCR?
Generally not on a rental-based investor loan. The ratio divides rent by the property’s PITIA, and the line payment typically sits outside it. A debt-to-income program works differently and counts the payment. Either way, you still owe the payment, so run your own cash-flow check.
Can I rent out the vacation home later?
A rental-based loan is business-purpose, so the property generally needs to be rented from the start. If you intend personal use first and rental later, discuss that upfront. The loan type should match how you will actually use the property.
What if my rental is held in an LLC?
An LLC cannot hold title on the line. You would need a vesting change, or a DSCR cash-out refinance instead. The purchase loan on the vacation home may allow an LLC, subject to lender program eligibility.
How much of the down payment can be borrowed?
It varies by program. Many accept borrowed money for the down payment and closing costs. A few cap the borrowed share, and the strictest want part of the down payment unborrowed. Borrowed funds are generally excluded from reserves.
