The Quick Read: A HELOC can supply the cash for a rental down payment, but it is only the first of two approvals: the HELOC lender underwrites you and your equity, and a separate purchase lender decides whether borrowed money counts and whether the rent covers the new loan. The strategy works best when you plan both steps before you draw anything.
- Order matters. The line has to exist before you go under contract. You cannot borrow against the property you have not bought yet.
- Leverage is higher than it looks. A HELOC-funded down payment on a purchase can mean borrowing close to 100% of the price across two liens.
- The coverage ratio leaves out the HELOC payment. Debt service coverage ratio (DSCR) counts only the new loan’s payment, but the HELOC payment still comes out of your pocket.
- Collateral choice sets the ceiling. On a primary residence, lines in Lendmire’s network reach up to 90% combined loan-to-value (CLTV), and only at a 720 credit profile. On an investment property the ceiling is 70% CLTV.
- Lender treatment varies. Some purchase programs accept documented line proceeds, some cap the borrowed share, and some want part of the down payment in your own seasoned funds.
Where Does the Equity Come From?
You have two realistic sources: a line on the home you live in, or a line on a rental you already own. Across the wholesale network Lendmire works with, a primary-residence line gives far more leverage than a rental-secured one. The rental-secured line carries a tighter set of rules and a hard cap.
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.
| Factor | Line on your primary home | Line on an existing rental |
|---|---|---|
| Max CLTV | Up to 90%, only at 720+ | 70% |
| Minimum credit | 600 program floor | 700 |
| Line size | $25,000 to $750,000 | Up to $500,000 |
| Draw structure | 3-yr or 5-yr interest-only draw | 5-yr draw, 25-yr repayment |
| What is at risk | Your home | The rental |
Two details change the picture. First, an investment-property line has no tier above 70% CLTV. A credit score above 700 buys you eligibility, not extra leverage. Second, the title has to sit in your personal name or an inter vivos revocable living trust. LLCs, corporations, and partnerships cannot hold title on these lines. A rental already deeded to an LLC needs a vesting change before it can secure a HELOC, or it is a candidate for a DSCR cash-out refinance instead. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The line itself is a standalone line in first or second lien position. Lenders qualify you personally, with a maximum debt-to-income ratio of 50%, calculated on the interest-only payment at the maximum draw. Lines of $500,000 or less ordinarily use an automated valuation instead of a traditional appraisal, though a higher CLTV can trigger a second valuation. All of this is subject to lender guidelines and full file review, and HELOC programs through Lendmire’s network are available in its 16 full-service states, a narrower footprint than its DSCR lending.
How Much Cash Can the Line Produce?
The line equals your value times the CLTV ceiling, minus what you already owe. A HELOC lender caps the line at a share of appraised value and subtracts your existing mortgage balance. What remains is your potential line.
Run it with percentages. Say your primary home carries a first mortgage equal to 50% of its value, and you qualify at 720 or better. A 90% CLTV ceiling leaves up to 40% of the home’s value as a potential line. The same 50% balance on a rental-secured line at 70% CLTV leaves up to 20% of its value. Your actual line also depends on credit profile, valuation, and the dollar caps above.
One market explainer from Nasdaq walks through an 85% combined ceiling in a second-home example. That is a market illustration. On an investment-property line in Lendmire’s network, the ceiling is 70% CLTV.
Now compare the line to what the purchase needs. Most DSCR purchase files land at 75% to 80% loan-to-value (LTV), which means 20% to 25% down. Select programs reach 85% LTV on a purchase, which means 15% down, with roughly a 700 or better score. Closing costs and reserves come on top. Size the line to the whole bill, but remember that at least 75% of the line is drawn at closing, so you pay on most of it from the first day. A line sized for a larger ambition than the deal needs is a cost, not a cushion.
How Does the Purchase Lender Treat Borrowed Money?
This is the question most HELOC-for-down-payment explainers skip, and it decides whether the plan works. A HELOC does not buy the property. It supplies cash, and a separate loan closes the purchase. The purchase lender decides what the cash is worth on that file.
Across DSCR programs, lenders fall into three camps:
- They accept documented line proceeds. You show the HELOC closing documents, the draw confirmation, and bank statements where the cash landed.
- They cap the borrowed share. Some of the down payment can come from the line, and the rest must come from your own funds.
- They require unborrowed, seasoned funds for some or all of the down payment.
Seasoning is the waiting period funds must sit in your account before a lender counts them. Many lenders want to see a draw in your account for a while, not moved in the week before closing. Down payment and reserves can also be treated differently. Borrowed money might count toward one and not the other. Reserves are the months of payments you must hold in liquid funds after closing. They commonly run around 6 months of PITIA (principal, interest, taxes, insurance, and association dues). They vary by lender, leverage, loan size, and transaction type. Conservative files at modest leverage under $1,500,000 can see them waived, and larger loans typically step up to about 9 months.
Because treatment is program-specific, the right move is to ask before you draw. A broker who sees many lenders’ guidelines can tell you which camp a program sits in. Lendmire’s piece Can You Use a Rental HELOC as a Down Payment on Another Property? goes deeper on that angle.
The Sequence, Step by Step
The order below keeps the line, the draw, and the purchase from tripping over each other.
1. Decide the purchase structure first. Pick the leverage and the loan type. Confirm with a broker how the likely purchase lender will treat line proceeds.
2. Open the line before you shop seriously. Lines take time to set up, and the HELOC lender reviews your credit, equity, existing liens, and debt-to-income. Do not wait until you have an accepted offer.
3. Draw once, to the amount the deal needs. Deposit the cash in your own account. Keep the draw separate from personal spending so the paper trail stays clean.
4. Let the funds season where the program asks. Keep the HELOC closing documents, the draw confirmation, and the bank statements together.
5. Close the purchase loan separately. The DSCR loan is sized to the rental’s income against its own payment, not to your personal debt-to-income ratio.
6. Plan the payoff now. Decide whether rent, savings, or a later refinance retires the line.
How Does the HELOC Itself Behave?
A HELOC is an open-end line of credit, which means you can borrow, repay, and borrow again up to a limit. The CFPB describes a draw period during which you can spend up to your limit, and gives 10 years as an example.
Payments change when that period ends. The CFPB’s HELOC brochure says some plans require principal plus interest during the draw period while others allow interest-only payments. It adds that repayment then begins, often over ten or 15 years. It also warns that payments on an adjustable line can change even if you do not borrow more.
On lines through Lendmire’s network, pricing floats across both the draw and repayment periods and never converts to a fixed payment. Investment-property lines run one structure only: a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Primary-residence and second-home lines also offer a 3-year draw with a 17-year repayment. That is useful to know, because interest-only payments mean you are not paying down principal while the draw lasts.
Stress-Testing the Stacked Payments
Clearing the DSCR test is not the same as making money. DSCR divides monthly rent by the monthly PITIA on the new loan. That is all it measures. Repairs, vacancy, management, utilities, and capital expenses sit outside it, and so does your HELOC payment.
Run the numbers this way, using modeled assumptions rather than market data. Picture a purchase at 75% LTV on a standard rental where rent covers the new loan’s PITIA at roughly 1.20x. Here, 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios generally open better pricing and leverage. Now the 25% down payment comes from a HELOC. You have borrowed close to 100% of the price across two liens. Here is how that plays out.
| Scenario | What the purchase lender sees | What you feel |
|---|---|---|
| Rent on target | Roughly 1.20x coverage | Two payments, thin cushion |
| HELOC payment added | Still 1.20x | Cushion mostly gone |
| One vacant stretch | Same ratio, on paper | HELOC paid from your pocket |
| Draw period ends | Same ratio | Payment steps up on the line |
The lender’s number never moves, while your cash flow changes underneath it. That is why the strongest files clear two tests at once: enough equity and enough rental coverage. A larger down payment lowers the new loan’s payment and can lift the DSCR, but it never erases leverage caps, credit floors, reserve rules, or property eligibility.
Where the General Rule Breaks
A few situations bend the simple “borrow, then buy” story.
An LLC-owned collateral property. As noted, an LLC cannot hold title on these lines. A HELOC on a primary residence, usually titled personally, sidesteps the issue.
Selling the collateral. The HELOC must generally be paid off when the property securing it sells. If your plan includes selling the home, the line is not a long-term funding source.
The draw-period cliff. Payments often jump when principal repayment begins. The line you sized as cheap interest-only money becomes a full amortizing payment.
Exposure limits. A borrower can hold up to three lines, with combined exposure capped at $2,000,000 on one program and $750,000 on another. A borrower owning more than 15 financed properties is not eligible. Serial buyers hit these walls before they hit the equity wall.
Property type on the purchase side. DSCR financing is not offered on manufactured homes (single- or double-wide), log homes, or barndominiums. A HELOC does not change that. HELOC collateral also excludes manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned property.
The debt-load effect on later deals. Benzinga notes that a HELOC adds to total debt and can make approval for other mortgages and loans harder. That bites hardest with lenders that count personal debt-to-income. DSCR lenders mostly size to the property, but your credit report will still show the new line.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
What Is the Exit Plan?
Every HELOC down payment needs a payoff plan, because the line is adjustable and tied to your own residence. Most investors choose one of three exits.
| Exit | How it works | Main risk |
|---|---|---|
| Repay from rent and savings | Pay the line down over time | Vacancy slows the payoff |
| Cash-out refinance | Pull equity from the new rental | Needs seasoning and equity |
| Sell | Sale proceeds retire the line | Timing and price risk |
On the refinance route, a cash-out refinance on a standard rental tops out around 75% LTV across most of the network. On short-term-rental collateral it tops out around 70%. About 6 months of seasoning is the common expectation, so the refinance cannot happen on day one. Lendmire’s article Why Landlords Are Tapping Record Equity With a Rental HELOC covers the equity-access side of that decision. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Treat the refinance as a plan, not a promise. Lender guidelines, credit approval, and the property’s appraised value all have a say. If the only way the HELOC gets repaid is a refinance that might not happen, the deal depends on one assumption.
Is a HELOC Even the Right Tool?
Sometimes the better move is to need less cash.
| Option | Best fit | Watch for |
|---|---|---|
| HELOC on your home | Large equity, strong credit | Home is collateral |
| Cash-out on a rental | Rental with equity, 6+ months owned | Resets that loan |
| Higher-leverage purchase | Strong credit, solid coverage | Tighter credit tiers |
| Your own cash | Plenty of liquid savings | Less cash left over |
A high-leverage DSCR purchase may reduce the down payment you need. With roughly a 700 or better score, select programs reach 85% LTV on a purchase, which means 15% down. That can shrink the borrowing you need against your home. Most programs Lendmire places files with want around a 660 score, and a 620 floor exists in parts of the network. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000 the network generally holds to 30-year fixed structures. Extended terms and interest-only periods are available through select lenders, and adjustable structures exist for investors who want them. The complete DSCR loans guide walks through how these pieces fit together.
Go or No-Go? A Practical Checklist
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. That is why your personal borrowing and the property’s income get tested separately.
This strategy tends to fit when:
- You have meaningful equity after your existing mortgage, and your credit profile fits the line you want.
- The rental clears coverage with room to spare, not barely.
- You can carry both payments through a vacant stretch from your own cash.
- You have a written payoff plan that does not depend on one outcome.
Pause when:
- The deal only works if the HELOC covers the entire down payment, reserves, and closing costs.
- Coverage is borderline, and sub-1.00 programs, available through select lenders with leverage and terms adjusted, are your only path.
- Missing a HELOC payment would put your home at risk. Nasdaq names this as the main downside: your primary residence could be foreclosed on.
- You have not asked the purchase lender whether line proceeds count.
Key Terms Defined
HELOC (home equity line of credit): An open-end line secured by property you own that you can draw from, repay, and draw from again.
CLTV (combined loan-to-value): All loans secured by a property, added together, divided by its value.
DSCR (debt service coverage ratio): Monthly rent divided by the monthly payment on the new loan, including taxes and insurance.
PITIA: Principal, interest, taxes, insurance, and association dues, the monthly obligation DSCR compares to rent.
Seasoning: The waiting period before a lender counts funds or lets you refinance.
Lien position: Where a loan stands in line for repayment if the property is sold or foreclosed.
Frequently Asked Questions
Can I use a HELOC on the rental I am about to buy?
No. A line needs collateral you already own, and you cannot borrow against a property you have not closed on. The line comes from your primary residence, a second home, or a rental you already own. After you buy, the new property can be a candidate for later financing.
Will a DSCR lender accept HELOC money as my down payment?
It depends on the program. Some accept documented line proceeds, some cap the borrowed share, and some want part of the funds unborrowed and seasoned. A broker who works with many lenders can tell you which camp a program falls into before you draw.
Does the HELOC payment lower my DSCR?
Not on paper. The ratio compares rent to the new loan’s payment only. But your cash flow absorbs the HELOC payment, along with vacancy and repairs. A strong ratio can sit on top of weak real-world cash flow.
How much can I borrow on an investment-property line?
On an investment property, lines through Lendmire’s network reach up to 70% CLTV and cap at $500,000 total. The minimum credit score is 700, and the draw runs 5 years followed by a 25-year repayment. Figures remain subject to lender guidelines and file review.
Should I use a HELOC if I can wait and refinance instead?
Often yes, wait. If your existing rental has been owned for about 6 months, a cash-out refinance at up to roughly 75% LTV on a standard rental may be a cleaner source of funds. That route avoids tying your own home to the deal, though it resets that loan.
