The Quick Read: A home equity line of credit on your primary residence can fund the down payment on a second home, but whether the purchase lender will accept borrowed money is the deciding question, and the answer changes by lender, by loan type, and by which part of the cash to close the money covers. A named list of banks goes stale and ignores your file, so this guide covers which kinds of lenders say yes and what they check.
- A line of credit changes where the down payment comes from. It does not remove the down payment requirement.
- Lines on a primary home are widely offered. Lines secured by an investment property are thinner.
- On Lendmire’s wholesale network, primary-residence and second-home lines reach 90% combined loan-to-value at a 720-or-better credit profile, and investment-property lines stop at 70%.
- Tell the purchase lender about the plan before you draw.
Key Terms Defined
You will see these terms throughout, so here they are once.
- Combined loan-to-value (CLTV): your first mortgage balance plus the new line, divided by the home’s value.
- Draw period: the stretch when you can borrow from the line, often paying interest only.
- Repayment period: the stretch after the draw period when you pay back principal and interest.
- Source of funds: the paper trail that shows where your down payment came from.
- Debt-to-income ratio (DTI): your monthly debt payments divided by your monthly income.
- PITIA: principal, interest, taxes, insurance, and association dues on a loan.
- DSCR: the debt service coverage ratio, which is a property’s monthly rent divided by its PITIA.
- Seasoning: how long money has sat in your account, or a loan has existed, before a lender counts it.
- Reserves: cash you still hold after closing.
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 Down Payment Works, Step by Step
A HELOC is a revolving credit line secured by a home. You borrow against equity, spend the cash on anything, and the purchase loan for the second home is a separate transaction with its own rules. Five steps carry the whole process.
Step 1: Pick the collateral. The usual choice is your primary residence, because lenders write the most lines against it. A second home or an existing rental can also secure a line, but fewer lenders will do it. A first-time investor has no rental to borrow against, so a primary-home or second-home line is the only route.
Step 2: Open the line. The line lender reviews your equity, your credit, and usually your debt-to-income ratio. A closed-end home equity loan is the alternative. It pays out a lump sum at once instead of letting you draw as needed.
Step 3: Draw and document. Move the money into your own account and keep the line agreement, the draw statement, and the deposit record. The purchase lender will ask where the cash came from.
Step 4: Qualify for the purchase loan. This is where the loan type matters, and the next sections cover it in full.
Step 5: Disclose before you draw. A new credit line shows up on your credit report. It also changes your monthly obligations. Telling the purchase lender first lets them tell you whether the draw helps or hurts the file.
One point catches people off guard. On the wholesale programs Lendmire places files with, at least 75% of the line is drawn at closing. You cannot open a large line and leave it idle, so interest starts on most of it right away.
Which Kinds of Lenders Offer This?
Primary-home lines are widely available across lender types. Lines secured by an investment property are thinner and tend to come from lenders with more flexible local policies. The lenders that write the loan you need depend on the collateral, your credit profile, and your combined leverage, so categories tell you more than a brand list.
| Lender type | What to expect | Ask them |
|---|---|---|
| Large retail banks | Primary-home lines common | Is investment collateral allowed? |
| Community banks, credit unions | More policy flexibility | Do you allow borrowed down payments? |
| Regional banks | Mixed policies by product | What credit and CLTV tiers apply? |
| Wholesale lenders via a broker | Structured program tiers | Which program fits my property? |
Lendmire is a mortgage broker, not a lender. It works with a network of wholesale lenders and matches your scenario to a program, which saves you from calling lenders one at a time. Home equity line placement through Lendmire is limited to its 16 full-service states, which is narrower than its 41-market DSCR footprint, so confirm availability early.
Before you apply anywhere, ask five questions:
1. Does the line allow its proceeds to fund a second-home or investment purchase?
2. What maximum CLTV applies at my credit score and occupancy type?
3. Is the line variable, and what happens when the draw period ends?
4. Will the purchase lender need the line open and posted before the application?
5. Does the line sit in first or second lien position?
What the Network’s Equity Lines Look Like
Lendmire places lines with two wholesale programs. One pairs a 3-year interest-only draw with a 17-year repayment period. The other, the longer-runway program, pairs a 5-year draw with a 25-year repayment period. Both require at least 75% of the line drawn at closing. Pricing floats during both the draw and the repayment period and never converts to fixed.
The CFPB’s guide to using home equity describes a usual draw period of ten years across the broader market. It also says lenders typically want you to keep 10% to 20% of your home’s value as equity. The network’s draw periods run shorter. Its leverage ceilings, shown below, sit at the thin end of that equity cushion.
For a second home used as collateral, the maximum CLTV steps up with credit profile. These limits apply on lines up to $500,000.
| Credit profile | Max CLTV, second home |
|---|---|
| 720+ | 90% |
| 700+ | 85% |
| 680+ | 85% |
| 660+ | 80% |
| 640+ | 75% |
A primary residence also reaches 90% CLTV at 720 or better. An investment property stops at 70% CLTV, with no tier above it. Investment lines also run only the 5-year draw and 25-year repayment structure. Any market survey that reports higher equity-line limits describes the wider market, not this network.
Other program features worth knowing:
- Line size: $25,000 to $750,000. A second home caps at $500,000.
- Credit floor: the program floor is 600. A second-home line needs 640, and an investment line needs 700.
- DTI: 50% maximum, and 45% for profiles from 600 to 679. The lender reviews your file on the interest-only payment calculated on the maximum draw.
- Valuation: lines at or below $500,000 ordinarily use an automated valuation. You can request a full appraisal in any case.
- Title: the individual borrower or a revocable living trust must hold title. Subject to program terms, a DSCR loan can close in an LLC, but an equity line cannot.
- Exposure: a borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible.
- Past credit events: a bankruptcy needs 4 years of seasoning from discharge or dismissal.
Every figure here is subject to lender guidelines and a full file review. None of it is a commitment to lend.
The Equity Math in Percentages
Say your primary home carries a first mortgage equal to 55% of its value. A 720-plus credit profile on a primary residence can reach 90% CLTV, but this example uses an 85% limit, so the line can reach 30% of the home’s value. That 30% is the pool for your second-home down payment.
A 20% down payment on a second home needs a pool equal to 20% of its price. That works when the second home costs up to about one and a half times your primary home’s value. The math is simple. The tight part is almost always combined leverage, not credit. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
How the Purchase Lender Treats Borrowed Funds
The purchase lender, not the line lender, decides whether borrowed funds count. Its answer can differ for the down payment, the closing costs, and the reserves. Two loan types handle the line very differently.
Debt-to-income loans. A traditional second-home mortgage counts your new line payment in your DTI. Some lenders count a share of the credit limit even when the balance is zero. A drawn line adds a visible payment, and that can push you over the lender’s DTI limit.
DSCR loans. 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. The line payment is not part of the property’s coverage ratio, although it still strains your personal finances. The complete DSCR loans guide walks through the ratio in full.
A true second home you will use personally is a different program from an investment property. Occupancy rules differ, and renting the home out triggers investment-property treatment. If the plan is a pure rental, a DSCR purchase is the natural fit.
Here is what that looks like across the wholesale network:
- Purchase leverage: most DSCR purchases land at 75%-80% LTV, which is 20%-25% down. Select programs reach 85% LTV with roughly a 700+ score.
- Coverage: 1.00 is where many select programs start. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
- Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Reserves: commonly around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type.
A larger down payment lowers the payment and can lift the coverage ratio. It does not erase leverage caps, credit floors, or reserve rules. Clearing 1.00 also does not mean positive cash flow, because repairs, vacancy, management, and utilities sit outside the calculation.
Where the General Rule Breaks
A fully borrowed down payment. Some programs accept it. Others require a minimum of your own cash or cap the borrowed share.
Seasoning of borrowed funds. Lender policy varies. Some lenders only want to see the payment and the paper trail. Others want the money to sit for a while first.
A property already in an LLC. Because an LLC cannot hold title on an equity line, you need a vesting change first, or you can use a DSCR cash-out refinance instead.
Ineligible collateral. Manufactured homes, co-ops, condotels, and log homes are not eligible for the lines described above. Manufactured homes, log homes, and barndominiums are also not offered under the network’s DSCR programs.
Variable payments. The FTC describes a HELOC as revolving credit secured by your home, with a typically variable cost. Your payment can rise during the draw and can jump when repayment begins. A long-term hold with a thin cushion is the situation this hurts most.
Falling values. Lenders can reduce a line when a home’s value drops. That matters most if you counted on drawing more later.
What Goes Wrong: A Stress Test
Three obligations stack up: your first mortgage, the line, and the new mortgage. A rental’s rent has to carry the new loan and, in practice, help carry the line payment too. Two loans resting on one rent stream make the cash-flow test harder.
Run the stress test before you draw. Ask yourself four things:
1. Could you carry all three payments if the new property sat empty for a few months?
2. What happens to your budget if the line’s payment rises when repayment begins?
3. Is your combined leverage still comfortable if your home’s value dips?
4. Does the new property’s coverage ratio hold up at lower leverage?
Common Misreads
The line is invisible to the new lender. It is not. The purchase lender reviews your credit report and your source-of-funds documents.
A HELOC replaces the down payment. It changes where the money comes from. The requirement stays.
HELOC payments count in the DSCR ratio. They do not. They still count in your personal budget.
Any bank will do an investment-property line. Availability is thin and varies by lender.
HELOC pricing is fixed. It typically floats and, on the programs described here, never converts to fixed.
Who This Fits
This works best for an owner with substantial equity and strong credit who plans to pay the line down. It also works when the second property’s rent clearly carries its own loan. It suits a buyer who can show a clean paper trail and has told the purchase lender early.
This is a poor fit if your combined leverage is already tight. It is also a poor fit if you plan to leave a variable line open for years against a thin-margin rental. And it fails if the purchase lender caps borrowed funds below what you need.
If a debt-to-income loan breaks on the line payment, a rent-qualified DSCR purchase loan avoids the personal-income test. The property’s own rent still has to support the loan.
Frequently Asked Questions
Do any banks allow a HELOC for a second-home down payment?
Many lines allow the cash to be spent on anything, so the line lender usually does not restrict the use. The purchase lender is the one that decides whether borrowed money counts. Ask both before you apply. A broker that shops several wholesale lenders can match your equity, credit, and property to a program that fits.
Can a HELOC also cover closing costs and reserves?
Down payment, closing costs, and reserves are separate tests. A lender may accept borrowed funds for one and not another. Many programs will not count borrowed money toward reserves, so plan to hold some of your own cash.
How much equity do I need?
It depends on your credit profile and the home’s value. On Lendmire’s network, a second-home line tops out at 90% CLTV at a 720-or-better credit profile, and 85% at 680 or higher. Subtract your first mortgage from that figure to see your pool, as the percentage example above shows.
Can an LLC own the home securing the line?
No. Title must sit with the individual borrower or a revocable living trust. An LLC-owned property needs a vesting change, or a DSCR cash-out refinance may be the better route, subject to lender program eligibility.
Does the line payment hurt my DSCR?
It does not enter the property’s coverage ratio, because DSCR compares rent to the new loan’s PITIA only. The payment still affects your personal finances, and a debt-to-income lender will count it.
