The Quick Read: Yes, you can use a home equity line on your current home to fund a second-home purchase, but the line supplies cash and does not buy the house, and the lender financing the new property decides whether it accepts those borrowed funds. Most borrowers use the draw for the down payment and closing costs, not the whole price. If the second home will be a rental, the purchase usually moves to a DSCR loan, which looks at the rent instead of your personal income.
- A HELOC is a separate loan secured by your current home, so you carry two approvals and two payments.
- On Lendmire’s network, a line on a primary residence or second home reaches 90% combined loan-to-value (CLTV) only with a 720-or-better credit profile, and an investment-property line stops at 70% CLTV.
- The purchase lender can still require reserves, a minimum credit score, and documentation of where the cash came from.
- If the new property is a rental, DSCR lender review runs mainly on rent against the payment, subject to lender guidelines.
- Your current home is the collateral, so a missed payment on the line puts that home at risk.
How Does a HELOC Actually Fund a Second Home?
A HELOC pays you cash from the equity in your current home. You then spend that cash like any other savings: on the down payment, on closing costs, or in rare cases on the whole purchase. The line never touches the new property. The new property gets its own loan, with its own lender, its own appraisal, and its own rules.
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.
Equity is simply the home’s value minus what you still owe on it. A HELOC lets you borrow against that gap again and again during a set period. Lenders measure the total debt against the home’s value with a ratio called combined loan-to-value, or CLTV. That ratio adds the first mortgage and the new line together, then divides by the value.
The sequence matters. You open the line and draw the cash before you close on the new home, because the purchase lender wants to see the money in your account. You cannot open a line on the property you are buying until you own it, so a line on the new home is a post-purchase tool, not a down-payment source.
What Does a HELOC Cost You Beyond the Down Payment?
The cost is a second monthly obligation that sits on top of your current mortgage and the new loan. Lines are interest-only during the draw period and then fully amortizing, so the payment steps up later. The pricing also floats, which means your cost moves with the market.
Lendmire’s network offers two draw structures on primary residences and second homes. One runs a 3-year interest-only draw followed by a 17-year repayment. The other runs a 5-year draw followed by a 25-year repayment. Investment-property lines use the 5-year draw and 25-year repayment structure only. Pricing floats across both the draw and repayment periods on every structure and never converts to a fixed figure.
Here is a detail many borrowers miss: at least 75% of the line is drawn at closing on both structures. That means you start paying interest on most of the line immediately. It works well when you need the cash now. It works poorly if you wanted a large undrawn safety net.
The CFPB’s HELOC booklet explains how lenders set the limit: they take a percentage of your home’s appraised value, subtract your mortgage balance, and then review your income, debts, and credit. The booklet is dated, so treat its sample percentage as an illustration only. The structure of the calculation still holds.
What Will a HELOC Lender Look At?
A HELOC lender underwrites you and your home, not the property you plan to buy. Expect a review of equity, credit, income, and existing debts.
Across Lendmire’s wholesale network, the main HELOC guidelines look like this, subject to lender guidelines and full file review:
- Line size: typically $25,000 to $750,000. A line above $500,000 is for primary residences only, needs a 700-or-better credit profile (720 on the longer-runway structure, the 5-year draw and 25-year repayment option), caps at 75% CLTV, and requires a full appraisal.
- Credit: programs start at a 600 floor. Second-home lines floor at 640 and investment lines at 700, and the strongest CLTV tiers need higher scores.
- Debt-to-income (DTI): typically up to 50%, 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, and every line above $500,000 needs a full appraisal.
- Title: the borrower must hold the home individually or in a revocable living trust. An LLC cannot hold title on these lines.
- Exposure: a borrower can hold up to three lines, and an investor with more than 15 financed properties is not eligible.
- Availability: HELOC lending runs through Lendmire’s 16 full-service states, a narrower footprint than its 41-market DSCR coverage.
Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible. Single-family homes, 2-4 unit properties, PUDs, townhomes, and condominiums, including non-warrantable condos, are. These guidelines apply to the property that secures the line, which is your current home.
Which CLTV Ceiling Applies to Your Situation?
The ceiling depends on what the securing property is, and it climbs only with credit. On a primary residence or a second home, the network tops out at 90% CLTV, and only at a 720-or-better credit profile. On an investment property, the ceiling is 70% CLTV with no higher tier.
On a second-home line, the tiers step down with credit. A 720+ profile reaches 90% CLTV up to $500,000. A 700+ or 680+ profile reaches 85%. A 660+ profile reaches 80%, and a 640+ profile reaches 75%.
Market sources run higher for some lenders. NerdWallet reports that not every lender offers a HELOC on an investment property, and that those who do apply stricter standards. It cites typical market figures of a 720 or higher credit score and an 80% maximum LTV. Those are market-wide figures. On Lendmire’s network, an investment-property line is capped at 70% CLTV.
Most people reading this want to know how the line on their own home fits. If you live in the home, your line sits at the primary-residence tier. If you plan to rent out your current home and move, treat the line as an investment-property line and the CLTV drops to 70%.
Will the Second-Home Lender Accept HELOC Money?
Often yes, but this is the real gate. The HELOC is rarely the problem. The purchase lender decides whether borrowed, secured funds can serve as your down payment, and programs differ.
Many lenders accept a documented draw. Others want a minimum from your own unborrowed funds. A plan built on a fully borrowed down payment can fail on that point alone. Ask the purchase lender before you draw, not after.
Expect a paper trail:
1. The HELOC statement showing the draw.
2. The bank statement showing the deposit.
3. The funds sitting in your account before closing.
How long the money must sit varies by program, so confirm it with the purchase lender.
The HELOC does not waive anything else on the purchase loan. Down payment minimums, credit floors, and reserves still apply. Reserves, meaning cash left over after closing, commonly run around six months of the full monthly obligation. They vary by lender, leverage, loan size, and transaction type. Some conservative files at modest leverage can see reserves waived, and larger loans typically step up.
On a loan that tests your debt-to-income ratio, the new HELOC payment counts as a debt and can pinch your approval. That is one reason borrowers who plan a rental purchase look at DSCR financing instead.
Second Home or Rental? The Label Changes the Loan
A second home is for personal use, such as a vacation place. A rental is an investment property. Lenders price and underwrite them differently, so document the intended use accurately.
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. If your plan is to buy a second property and rent it out, the practical route is usually a DSCR loan, not a second-home mortgage.
DSCR means debt service coverage ratio. You divide the property’s monthly rent by its monthly housing obligation, which covers principal, interest, taxes, insurance, and any HOA dues. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide walks through the full calculation.
The two tests work together. The HELOC proves you have the cash. The DSCR loan proves the rental can carry its own payment. The strongest files clear both: enough equity and enough rental coverage.
What Do DSCR Purchase Terms Look Like With HELOC Money?
Across most programs we place files with, DSCR purchase loans land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select programs reach 85% LTV on a purchase (15% down) with roughly a 700+ credit score. Loan sizes typically reach up to $3,000,000 on standard programs, with smaller balances available through select lenders, and above $2,500,000 the network generally holds to 30-year fixed structures.
On 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 pricing and leverage.
On credit, a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
Picture an investor with a rental in mind and a clean credit profile. They draw on a line against their home to cover the 20% down on a purchase at 80% LTV. The rent covers the new property’s full payment at roughly 1.2x. The DSCR loan doesn’t count the HELOC payment in that ratio. The investor still has to carry that HELOC payment from their own budget while the rental ramps up. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
A coverage ratio above 1.00 is not the same as positive cash flow. DSCR compares rent to the housing payment only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. Your personal budget has to absorb them, plus the HELOC payment.
A larger down payment lowers the new loan’s monthly payment and can lift the DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. Manufactured homes, log homes, and barndominiums are not offered on these DSCR programs. Lendmire’s piece Can You Buy an Investment Property With a HELOC on Your Current Home? goes deeper on the rental side.
HELOC vs. Cash-Out Refinance vs. Savings
Three sources of down-payment cash cover most of what investors consider. They differ in cost structure and in how the purchase lender sees them.
| Factor | HELOC | Cash-out refinance | Savings |
|---|---|---|---|
| Replaces current mortgage | No | Yes | No |
| Payment type | Interest-only draw, then amortizing | Fixed amortizing payment | None |
| Network leverage cap | 90% CLTV at 720+ (primary) | About 75% LTV on a cash-out | Not applicable |
| Seasoning | Varies by program | About 6 months common | Not applicable |
| Added risk | Floating pricing | Resets your mortgage | Lower liquidity |
A HELOC leaves your existing first mortgage untouched, which matters if your current mortgage terms are favorable. A cash-out refinance replaces it. Savings avoid new debt entirely. CBS News reports that tapping home equity can spare you from draining savings or cashing out investments, which is the main liquidity argument for a line.
The Edge Cases That Trip Borrowers Up
A few situations come up often enough to name.
A fully borrowed down payment. Some purchase programs require you to bring a portion of your own funds. Verify before you draw.
A line on a property held in an LLC. An LLC cannot hold title on a HELOC. A property already deeded to an LLC needs a vesting change or a DSCR cash-out instead.
A line on your current home that you plan to rent out. The CFPB’s HELOC brochure notes that renting out your home may be prohibited under the terms of a line of credit. Read your line agreement before you move out.
Selling the securing home. The same brochure says a sale generally requires you to pay the line off in full. If your plan involves selling the current home soon, the line has to be repaid at closing.
A frozen or reduced line. Lenders can limit or freeze a line when markets turn. Do not plan a purchase around an undrawn line you have not yet used.
A gifted line. If a relative’s HELOC funds your down payment, many programs treat the money as a gift, and gift rules vary by program and occupancy. Ask the purchase lender before you rely on it.
Risks and Exit Plans
Your current home secures the line. Falling behind on the HELOC can put that home at risk, even when the new rental performs. The CFPB’s brochure notes that HELOCs typically carry variable pricing and may carry fees even when unused.
Stacking leverage across two properties raises the stakes. A job loss or a soft rental market hits both loans at once. Stress-test your plan with the rental vacant for a few months and see whether your personal budget can still carry the HELOC and your primary mortgage.
Every HELOC plan needs an exit. Common ones include paying the line down from the rental’s cash flow, refinancing the new property later to repay it, or selling an asset. If you plan a refinance exit, confirm any prepayment penalty on the new DSCR loan before you commit. A penalty can make an early cash-out refinance more expensive.
HELOC money fits best on short-horizon plays with a clear payoff, like a purchase with a rehab and refinance planned. It fits poorly on a thin-margin rental where the rent barely clears coverage and the line stays open for years.
Key Terms Defined
HELOC: a home equity line of credit, a revolving line secured by your home that you draw on as needed.
CLTV: combined loan-to-value, the total of all loans secured by a property divided by its value.
DSCR: debt service coverage ratio, a property’s rent divided by its monthly housing payment.
Reserves: cash you keep on hand after closing, usually counted in months of the full monthly obligation.
Seasoning: the waiting period a lender wants between two events, such as a cash draw and the purchase it funds.
Draw period: the stretch when you can borrow from the line, typically with interest-only payments.
Is This Plan Right for You?
A HELOC-funded purchase tends to work when most of these are true:
- You have meaningful equity and a credit profile in the higher tiers.
- The purchase lender has confirmed it accepts borrowed down-payment funds.
- The new property’s rent covers its own payment with room to spare.
- Your personal budget can carry the HELOC payment if the rental sits empty.
- You have a written exit plan for repaying the line.
If you miss on two or more of these, consider a smaller draw, a longer wait, or a different source of cash.
Frequently Asked Questions
Can I use a HELOC as the full down payment on a second home?
Sometimes, but it depends on the purchase lender. Some programs accept a documented secured draw for the whole down payment. Others require a portion of your own unborrowed funds. Confirm the rule before you draw, because a fully borrowed plan can fail on that point alone.
Does the HELOC payment count against me on a DSCR loan?
It generally does not enter the DSCR ratio, because that ratio compares the rental’s income to the new property’s payment. On a loan that tests your debt-to-income ratio, the HELOC payment counts as a debt. Either way, it still hits your own budget and puts your current home at risk if you fall behind.
Can I get a HELOC on a rental property to buy another one?
Yes, with tighter limits. Not every lender offers lines on investment properties, and those who do apply stricter standards. On Lendmire’s network, an investment-property line caps at 70% CLTV and uses the 5-year draw and 25-year repayment structure only. HELOC lending runs through the 16 full-service states, so availability depends on where the property sits.
How much of my home’s value can I borrow against?
It depends on occupancy and credit. On a primary residence, the ceiling reaches 90% CLTV only at a 720-or-better credit profile. On a second home, tiers run from 75% CLTV at a 640+ score up to 90% at 720+, on lines up to $500,000. Lines above $500,000 are primary-residence only and cap at 75% CLTV.
Is a HELOC or a cash-out refinance better for buying a second property?
Neither wins every time. A HELOC leaves your current mortgage in place, while a cash-out refinance replaces it and tops out around 75% LTV with about 6 months of seasoning as the common expectation. The better choice depends on your existing mortgage terms, how much cash you need, and how long you plan to carry the debt. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
