The Quick Read: A home equity line of credit (HELOC) can fund a vacation rental down payment when the line is opened and drawn first, the collateral property has enough equity, your credit meets the line’s floor, and the purchase lender accepts borrowed money as down payment funds.
- Two separate approvals decide this: one for the line, one for the rental purchase loan.
- On Lendmire’s network, a line secured by a primary residence reaches up to 90% combined loan-to-value (CLTV) only at a 720 credit profile or better. A line secured by an investment property tops out at 70% CLTV, needs at least a 700 score, and caps at $500,000.
- Timing matters: the cash must already be in your account before you go under contract.
- Clearing the rental’s coverage test does not make the deal cash-flow positive once the line’s payment is added.
Lendmire is a mortgage broker. It arranges DSCR investor loans across 41 markets, including Washington, D.C., through select lenders in its wholesale network. Every figure below is subject to lender guidelines and full file review. Nothing here is a commitment to lend.
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.
How a HELOC Fits Into a Vacation Rental Purchase
A HELOC is a second loan, not a purchase loan. It borrows against equity in a property you already own and gives you cash. You then use that cash as your own funds on the rental purchase.
The line itself is a revolving credit line secured by the home. You borrow, repay, and borrow again up to a limit. When a first mortgage already sits on the property, the line becomes a second mortgage on top of it.
Funds from the line are generally usable for any purpose. Yahoo Finance says homeowners can tap primary-residence equity for the down payment on a vacation home or investment property. The same piece says the money can also cover closing costs, up to the approved limit.
Here is the catch. The line’s lender only looks at the home you pledge and at you. It does not care what the rental purchase loan looks like. The purchase lender decides separately whether borrowed money counts as acceptable down payment funds. That second decision is the gate.
What Decides Whether the Line Works
Three things drive the outcome: the equity in the collateral property, your credit, and how the purchase lender treats borrowed funds. Each has its own test. A file needs to clear all three.
The strongest files show both enough equity to pull the cash and enough rental income to cover the property’s own payment. Strength on one front does not make up for a shortfall on the other.
Equity and combined leverage
Lenders cap the combined loan-to-value ratio. That counts your existing first mortgage plus the new line, measured against the property’s value. The cap depends on what the collateral property is.
| Collateral property | Max CLTV | Minimum credit | Max line |
|---|---|---|---|
| Primary residence | 90% (720+ only) | 600 program floor | $500,000 at 90% CLTV; $750,000 at 75% CLTV, 700+ (720 on the longer-runway program) |
| Second home | 90% (720+ only) | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
These are typical ranges from select lenders in the network, not promises. Credit above 700 on an investment line buys eligibility, not extra leverage. Both the 700 and 720 tiers stop at 70% CLTV.
A line above $500,000 is primary-residence only. It needs a 700 score or better, or 720 on the longer-runway structure, which pairs a 5-year interest-only draw with a 25-year repayment. It caps at 75% CLTV and requires a full appraisal.
Take a modeled example in percentages only. Say your primary residence carries a first mortgage equal to 50% of its value. At a 720 profile and the 90% ceiling, you have roughly 40 points of value to borrow against. Now suppose the vacation rental costs only a fraction of your home’s value. A typical down payment would use up only a portion of that available equity, so closing costs and a cushion still fit. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Change one input and the picture shifts. If your first mortgage is already at 75% of value, the line has almost nothing to work with. If the collateral is an investment property instead, the 70% ceiling cuts the room sharply.
Credit and debt-to-income
Most lines in the network want a score in the 700 range or better for the strongest terms. The program floor sits at 600, but second homes start at 640 and investment lines at 700. A line is qualified on a debt-to-income ratio (DTI) of 50% at most. The payment used is the interest-only payment on the maximum draw, not on what you plan to use.
DTI is your monthly debts divided by your monthly gross income. Here it matters for the line, not for the rental purchase. The DSCR loan looks at the property’s income instead.
Your credit report cannot be more than 90 days old at closing. Bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure-family history follows different seasoning paths depending on the program and the occupancy of the collateral.
Valuation and structure
An equity line at or below $500,000 ordinarily runs on an automated valuation instead of a full appraisal. That means an investment-property line, which caps at $500,000, commonly closes with no traditional appraisal. Anything above $500,000 gets a full appraisal. You may also request one yourself.
Lendmire places HELOC files with two wholesale programs. Both are standalone lines that sit in first or second lien position. One program uses a 3-year interest-only draw followed by a 17-year repayment. The other uses a 5-year interest-only draw followed by a 25-year repayment. Investment-property lines run only the 5-year draw and 25-year repayment structure.
At least 75% of the line is drawn at closing. Pricing floats during both the draw and the repayment period. It never converts to fixed. That 75% draw rule matters for sizing. You carry cost on most of the line from day one, so a line much larger than you need is not free.
Title, property type, and exposure
The line must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. If the collateral property is deeded to an LLC, you need a vesting change first, or a different tool such as a DSCR cash-out.
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 zoning are not eligible. A borrower is limited to three lines in total. An investor owning more than 15 financed properties is not eligible.
HELOC placement runs in Lendmire’s 16 full-service states.
How the DSCR Lender Treats the Borrowed Cash
The purchase loan is judged on the rental property, not on your personal DTI. The lender divides the rent by the full monthly housing obligation on the new loan (principal, interest, taxes, insurance, and any HOA dues). That ratio is the debt service coverage ratio, or DSCR. DSCR loans are designed for investment properties. Because they are business-purpose loans, they are reviewed differently from a standard owner-occupied mortgage.
For coverage, 1.00 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 leverage and pricing. Read more in Lendmire’s complete DSCR loans guide.
Borrowed down payment money is a program-level question. Some programs accept a fully borrowed down payment. Some cap the borrowed share. Some want part of the down payment from your own funds. Many programs also refuse to count borrowed funds toward reserves, even when they allow them for the down payment.
Those separate pots are tested separately. The down payment, closing costs, and reserves each get their own review. A common reserve expectation is around six months of PITIA (principal, interest, taxes, insurance, and association dues). It varies by lender, leverage, loan size, and transaction type.
A bigger down payment helps the file. It lowers the new loan and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility.
Typical purchase leverage runs 75% to 80% LTV on a standard rental purchase, which means 20% to 25% down. Select programs reach 85% LTV on a purchase (15% down) with roughly a 700+ score. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Vacation Rental or Second Home? The Label Changes the Path
How you classify the property changes the underwriting. Bankrate notes that projected rental income can’t be used to qualify when the property is a second home, though it may be usable if the property is intended as a rental. A true vacation rental that you will not occupy runs on the investor path, where a DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
For short-term rentals, select programs in the network allow purchase leverage up to 75% LTV. Expect a score of 640 or higher and about 12 months of hosting history. The coverage floor on a short-term rental purchase is 1.00. 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. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
DSCR on manufactured homes (single- and double-wide), log homes, and barndominiums is not offered in the network. A vacation cabin built that way will not work, no matter how large the down payment.
Where the General Rule Breaks
The basic rule is that you can borrow the down payment from home equity. Here is where it stops working.
The purchase lender refuses borrowed funds. The line’s approval means nothing in that case. Ask the purchase lender in writing before you open anything.
The line is too small. A line has to cover the down payment, closing costs, and a cushion. At the 70% investment ceiling, equity often runs short before the 90% primary ceiling does.
The collateral sits in an LLC. This network’s lines require you or a revocable trust to hold title. Check this first if your rental is titled in an entity.
The collateral is an investment property. The White Coat Investor says investment-property HELOCs are often harder to qualify for and fewer lenders offer them. On this network, the line is also tighter: 70% CLTV, a 700 minimum score, and a $500,000 cap.
You rely on the line for reserves. Many programs will not count borrowed funds there. The reserves would need to come from your own account.
The collateral is a condotel or other ineligible type. A hotel-style condo unit is not eligible collateral for the line.
The Two-Payment Problem
A DSCR ratio counts only the new loan’s payment. Your line adds a second obligation that the ratio ignores. The rental now supports both, whether or not the lender’s formula sees that.
Run it as a model. A rental that covers its own purchase loan at around 1.2x can drop near or below 1.0x once the line’s payment joins the denominator. This is a test for you, not a lender requirement. It shows what happens in the slow months.
A DSCR above 1.00 does not mean positive cash flow either. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. A vacation rental with seasonal income feels this most, because thin months still owe two payments.
Variable pricing adds another risk. The Consumer Financial Protection Bureau describes a HELOC as a revolving line secured by home equity that usually carries an adjustable rate. The payment moves with the balance and the index. Stress-test it at a higher level before you draw.
The line is also secured by your home. If you fall behind, the lender can pursue the collateral property. That is the real cost of using home equity to buy a second asset.
Step by Step: The Order That Works
1. Pick the collateral. Your primary residence offers the most leverage, up to 90% CLTV at 720 or better. An owned rental caps at 70%.
2. Confirm the purchase lender’s position. Ask whether borrowed funds count for the down payment, closing costs, and reserves. Get the answer in writing.
3. Open the line and draw. The line is opened and drawn before the purchase, not alongside it. Move the cash into your own account.
4. Document the trail. Keep the line agreement, the draw statement, and the deposit record. A lender will want to see where the money came from.
5. Go under contract. The purchase lender tests the property’s income against its payment. It also tests down payment, credit, and reserves as separate pots.
6. Close the purchase. The rental carries its own first mortgage. Your collateral home now carries the line as a lien.
Step two protects you most. A line opened first with no answer from the purchase lender can leave you holding debt you cannot use.
Key Terms Defined
HELOC: A revolving credit line secured by home equity that you can draw from, repay, and draw from again.
CLTV (combined loan-to-value): All loans secured by the property, added together and divided by its value.
DSCR: Monthly rent divided by the full monthly payment on the property, used to judge whether the rental covers its own debt.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly housing cost on a loan.
Seasoning: The waiting period a lender requires between an event, such as owning funds or a property, and the next transaction.
Borrowed funds: Down payment cash that came from a loan instead of your savings, which some programs limit or exclude.
Frequently Asked Questions
Can I use a HELOC for the entire down payment on a vacation rental?
It depends on the purchase lender. Some programs accept a fully borrowed down payment, some cap the borrowed share, and some want part of it from your own funds. Ask in writing before you draw. A typical purchase runs 20% to 25% down at 75% to 80% LTV on a standard rental, and a program reaches 85% LTV with roughly a 700+ score. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
What credit score do I need for the HELOC itself?
It depends on the collateral. On Lendmire’s network, a second-home line starts at 640, and an investment-property line starts at 700. A primary-residence line has a 600 program floor, but the 90% CLTV ceiling requires 720 or better. Subject to lender guidelines and full file review.
Can I put the HELOC on the rental I already own?
Yes, on this network, if you hold title personally or in a revocable living trust. The cap is 70% CLTV, the minimum score is 700, and the line cannot exceed $500,000. A rental titled in an LLC cannot hold the line unless the vesting changes.
Does the HELOC payment lower my DSCR?
Not in the formula. A DSCR file compares rent to the new loan’s payment only. Your cash flow still bears both payments, so test the rental against the total.
Can the HELOC close at the same time as the purchase?
No. The line is closed and drawn before the purchase. Opening it late in a purchase also creates sequencing problems with the purchase lender.
