The Quick Read: A home equity line of credit can cover the down payment on a new home, but the lender financing the purchase decides whether borrowed money counts, and the line adds a third monthly payment you must carry every month from real cash flow. The line is its own loan with its own rules. Opening it is the easy part. Getting the purchase lender to accept it is the real test.
- A line is underwritten on the equity, credit, and income behind it, separately from the purchase loan.
- On Lendmire’s network, ceilings depend on how the property is used. An investment-property line tops out at 70% CLTV (combined loan-to-value). Primary-residence and second-home lines reach 90% CLTV only at a 720-or-better credit profile, and a primary-residence line above $500,000 caps at 75% CLTV.
- Borrowed down payment funds help the DSCR math by shrinking the purchase loan. They do not erase leverage caps, credit floors, or reserve rules.
Key Terms Defined
HELOC: A revolving credit line secured by your home. You borrow what you need, up to a limit, and owe interest on what you drew.
CLTV: Combined loan-to-value. It adds every loan on the property, including the new line, and divides by the property’s value.
Draw period: The stretch when you can pull money from the line, often paying interest only.
Repayment period: The stretch after the draw ends, when payments include principal and the balance is paid off.
DSCR: Debt service coverage ratio. It compares a rental’s monthly rent to its full monthly housing payment.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the payment the DSCR ratio is measured against.
Reserves: Liquid savings the lender wants you to hold after closing, usually counted in months of PITIA.
Lien position: Where a loan stands in line for repayment if the property is sold to settle debts. A first lien is paid first.
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.
Can a HELOC Really Fund a Down Payment?
Generally, yes. The line does not restrict how you spend the money once it is in your account. The restriction comes from the lender financing the new property.
SmartAsset notes that a homeowner with equity in a primary residence may be able to use a HELOC toward the down payment on a second home. It adds that lenders generally want a larger down payment on a second home and will check income and existing debts. Yahoo Finance makes the same point for a vacation home or investment property.
Lenders sort the buyer’s cash into separate buckets: the down payment, closing costs, and reserves. Borrowed money can be fine for one bucket and refused for another. That is why the first call should go to the purchase lender, not the line’s lender.
The appeal is liquidity. You keep savings in the bank while still meeting the down payment. This lets a buyer hold cash for other investments or an emergency fund. The cost is risk transfer. Your current home becomes collateral for the new purchase.
How the Process Runs, Step by Step
Think of it as two loans, built in order, that must work together.
1. Open the line first, on equity you already own. The line is judged on the property that secures it. Equity is that property’s value minus the mortgage and other liens against it. Open it before you make offers, not after you go under contract.
2. Draw the cash into your own account. Funds usually move by check, online transfer, or an attached card. On Lendmire’s network, at least 75% of the line is drawn at closing, and interest accrues on whatever is drawn, so plan for that balance from the start.
3. Document the source. Expect to give the purchase lender the line agreement, a statement showing the draw, and bank statements showing the deposit and the wire. Some lenders also want the drawn funds to sit in your account for a period before they count. Ask what that period is.
4. Let the purchase lender rule on it. It decides whether the borrowed money counts for the down payment, closing costs, and reserves.
5. Underwrite the purchase. A bank-style loan counts the new line payment in your debt-to-income ratio. A DSCR loan looks at the new property’s rent against its own payment. More on that next.
6. Carry three payments. You owe the existing mortgage, the line, and the new loan. Stress-test all three before you sign anything.
Sequence matters. A new line is a new account and a new inquiry on your credit. Opening it after the purchase application is underway can change the file the purchase lender already reviewed. Lendmire’s piece Top HELOC Providers to Fund a Down Payment on a New Home compares where these lines come from.
How Underwriting Treats the Line
The answer changes with the type of purchase loan.
On a conventional or bank loan, the line payment generally counts against you. Lenders add the new line payment, the new mortgage payment, and existing housing costs, then measure the total against your income. A buyer who qualified before the line may not qualify after it.
A DSCR loan works differently. 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 file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
That does not make the line free. The ratio may leave your personal debts out, but the line payment still has to be paid from your pocket. Two traps follow:
- DSCR is not cash flow. The ratio compares rent to PITIA only. Clearing the baseline says nothing about repairs, vacancy, management, utilities, or capital expenses. Leave room for all of them.
- The line payment sits outside the ratio. If the rental is thin and the line payment floats upward, the shortfall comes out of your own income.
The money flows the other way too. A larger down payment shrinks the purchase loan, which lowers the monthly payment and can lift the coverage ratio. That is arithmetic, not a program feature.
The DSCR Purchase Side
Here is what the rental loan itself typically looks like across Lendmire’s wholesale network. The full picture lives in the complete DSCR loans guide.
- Leverage on a purchase: Most files land at 75%-80% LTV, meaning 20%-25% down. Select programs reach 85% LTV (15% down) with roughly a 700+ score.
- 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.
- Credit: A 620 floor exists in parts of the network. Most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Reserves: They vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common, and larger loans typically step up to about 9 months.
- Loan size: up to $3,000,000 on standard programs (smaller balances available through select lenders).
The strongest files clear two tests at once: enough equity and enough rental coverage. Extra cash down lifts only the coverage test, since the equity test stands on its own. Borrowed funds are also commonly excluded from reserve counts at many lenders, so confirm how your purchase lender treats them.
For a cash-out refinance on a standard rental, leverage tops out around 75% LTV, with about 6 months of seasoning as the common expectation. That is a different tool, covered in the comparison below. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
What a Line Looks Like on Lendmire’s Network
Lendmire is a broker, not the lender. It places these lines with select wholesale partners, and every figure below is subject to lender guidelines and full file review. The ceiling depends on how the property securing the line is used.
| Occupancy | Top CLTV | Credit pairing | Max line |
|---|---|---|---|
| Primary residence | 90% | 720+ | $500,000 |
| Primary residence (larger line) | 75% | 700+ (720 on the longer-runway program) | $750,000 |
| Second home | 90% | 720+ | $500,000 |
| Investment property | 70% | 700+ | $500,000 |
The 90% figure exists only at a 720-or-better profile. Drop to 640 and the primary-residence ceiling falls to 80% CLTV, while a second home falls to 75%. Minimum credit is 600 on a primary residence, 640 on a second home, and 700 on an investment property.
A primary-residence line can reach $750,000. Anything above $500,000 is primary-residence only, needs a credit profile of 700 or better (720 on the longer-runway program, the one with the 5-year interest-only draw), caps at 75% CLTV, and requires a full appraisal. Below $500,000, an automated valuation ordinarily replaces the appraisal, though a higher CLTV may require a secondary valuation.
Other mechanics worth knowing:
- Structure: A standalone line in first or second lien position. Primary and second-home lines offer a 3-year interest-only draw with a 17-year repayment, or a 5-year interest-only draw with a 25-year repayment. Investment lines run the 5-year draw and 25-year repayment only.
- Pricing floats: It moves through both the draw and repayment periods and never converts to fixed.
- Debt-to-income: 50% maximum, 45% for credit profiles from 600 to 679, and anything above 45% needs at least a 680. Qualifying uses the interest-only payment calculated on the maximum draw.
- Exposure: A borrower is limited to three lines, and an owner of more than 15 financed properties is not eligible.
- Eligible property: Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural-zoned property are not offered.
- Availability: These lines are available in 16 states, a narrower reach than Lendmire’s 41-market DSCR footprint.
Which Property Should Secure the Line?
Most investors tap the home they live in. A line on a primary residence carries the highest ceilings on this network. A line on an existing rental is possible but capped at 70% CLTV, and investment-property lines are scarcer across the broader market.
One structural catch trips up investors who hold property in a company. Title on these lines must sit with the individual borrower or a revocable living trust. Subject to program terms, 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. That is the sharpest difference from a DSCR loan, where LLC ownership is common. For the DSCR side of tapping a property you own, see Lendmire’s article Top DSCR HELOC Providers to Cover a Down Payment on Another Home.
Where the General Rule Breaks
The headline is “yes, you can.” These edge cases are where it turns into “not on this file.”
Some lenders refuse borrowed funds outright. Some programs want the down payment unborrowed. If yours does, a line is not a down payment source, no matter how much equity you hold.
A fully borrowed down payment is the riskiest version. Combined leverage can approach the whole purchase price. Cash flow and reserves strain together. Whether a program accepts it varies.
The draw period ends. Payments can jump when interest-only converts to amortizing, so budget for the repayment payment as well as the draw-period payment. The FTC explains that many lines start with a draw period in which you may owe only interest on what you borrowed.
Pricing floats. The CFPB’s HELOC booklet says these lines typically carry variable pricing, so monthly payments may change. It also says plans secured by a dwelling must have a ceiling on how high the price can go. And lenders sometimes offer a temporary introductory price for a short period, after which it can be higher. Underwrite the loan at the later number, not the teaser.
You owe on what you draw, not on what is available. The FTC confirms you pay only on the amount borrowed. The unused line is still a liability sitting on your credit file.
A listed home may be ineligible. In several states, a property currently listed for sale, or listed within the past 60 days, is not eligible. That matters for owners who plan to sell the old home right after buying.
Equity is not unlimited. SmartAsset reports that some lenders require 15% or more down on an investment property. Leverage limits and credit tiers on the line itself still apply, whatever the purchase lender allows.
HELOC vs. the Other Ways to Pull Equity
| Option | Structure | Watch for |
|---|---|---|
| HELOC | Revolving line, floating pricing | Payment moves; draw period ends |
| Home equity loan | Lump sum, set repayment | Adds a second fixed obligation |
| Cash-out refinance | Replaces your first mortgage | Resets the whole loan; seasoning |
| DSCR cash-out on a rental | Rental-backed, rent-based qualifying | Around 75% LTV; about 6 months seasoning |
If you hold a rental free of an LLC and want to avoid putting your own home at risk, the DSCR cash-out on that rental is worth running. If your equity is in the home you live in, a line is usually the cleaner tool.
Does It Fit Your Plan?
This is a genuine toss-up for most buyers. The liquidity is real. So is the exposure.
A line fits best when there is a defined payoff, such as a short hold or a planned sale of the old home. It fits worse in a long buy-and-hold, because the line may outlive the plan and its payment can rise when the draw period ends.
Skip it if:
- The new property’s rent barely clears the baseline coverage and you have no cushion beyond it.
- Your reserves are thin once the draw lands.
- Your purchase lender excludes borrowed funds.
- Missing a line payment would put your primary residence at risk. SmartAsset says the primary residence could be foreclosed on if the line payments are missed.
Some borrowers also ask whether line interest is deductible. 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.
One last practical point. If you plan to repay the line at sale, build in the possibility that the sale slips. Hold the line payment and the new loan payment together in your stress test, for as long as you could realistically own both homes.

Frequently Asked Questions
Will the purchase lender accept a HELOC as my down payment?
It depends on the lender and the program. Some accept borrowed funds with documentation of the draw. Others want the down payment unborrowed. Confirm before you draw, and ask separately about closing costs and reserves, since lenders often treat each bucket differently.
Does a DSCR loan ignore my HELOC payment?
The DSCR ratio compares only the rental’s rent to its own payment. Personal debts are not part of that ratio. The line payment still comes out of your cash flow, so a thin rental with a floating payment can put real pressure on you even when the ratio looks fine.
Can I put a HELOC on a property held in an LLC?
Not directly. On Lendmire’s network, title on these lines must sit with an individual or a revocable living trust. A property already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead, subject to program terms.
How much can I borrow on an investment property?
On this network, an investment-property line is capped at 70% CLTV and $500,000, with a 700 minimum credit profile. Lines on a primary residence or second home can run higher, up to 90% CLTV at 720 or better.
Should I draw the cash before or after I find the property?
Open the line before you make offers, since the line is its own file. Draw only when the purchase lender tells you how it wants the funds documented. Because at least 75% of the line is drawn at closing on this network, plan for interest on most of the balance from the start.
