The Quick Read: A home equity line on property you already own can supply the cash for your down payment, but a separate DSCR loan buys the rental, and that purchase lender decides whether borrowed money counts toward your down payment, closing costs, and reserves, so you confirm its rules before you draw a dollar.
- The line must be open and funded before you go under contract. It has to be secured by a home or rental you already own.
- Across Lendmire’s wholesale network, an investment-property line tops out at 70% CLTV and $500,000, with a 700 minimum credit score. Primary-residence lines reach 90% CLTV only at a 720-or-better profile.
- DSCR compares rent to the new property’s payment only. It ignores the HELOC payment, but your monthly cash does not.
- Effective leverage on the deal can approach 100%, so the rent has to carry both loans.
- Borrowed-funds treatment differs from one DSCR program to the next. Ask before you draw.
Can a HELOC Really Pay the Down Payment?
Yes, investors do it routinely, and the line itself places no limit on where the cash goes. A HELOC (home equity line of credit) is a general-purpose credit line. Yahoo Finance confirms it can fund a down payment on a second home or an investment property.
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.
The catch sits on the other side of the deal. A HELOC supplies cash. It does not buy the rental. A second loan does that, and the lender on that second loan has its own view of borrowed money.
Most rental buyers pair HELOC cash with a DSCR loan. DSCR stands for debt service coverage ratio. The lender divides the property’s monthly rent by its monthly payment of principal, interest, taxes, insurance, and any HOA dues. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. For the full mechanics, see Lendmire’s complete DSCR loans guide.
Investors like this pairing for a plain reason. A conventional loan adds your new HELOC payment to your personal debts, and that can break the debt-to-income ratio. A DSCR purchase looks at the property instead. That does not make the HELOC free. It only moves where the test happens.
How Does the Two-Loan Sequence Work, Step by Step?
You are managing two separate loans and two separate approvals. Passing one review does nothing for the other. Strong rent will not rescue thin equity, and deep equity will not rescue weak rent coverage.
1. Size the line. The HELOC lender takes the home’s value, applies its CLTV limit, and subtracts what you owe. CLTV (combined loan-to-value) counts every loan against the property, not just the first mortgage.
2. Qualify for the line. This part rests on you: credit, debt-to-income, income documentation, and equity. With solid income, good credit, and plenty of equity, a line on a primary home is usually the easier of the two approvals. Without those three, it is not available.
3. Open it before the contract. You cannot open a line on a property you have not bought yet. Lenders can also freeze or reduce a line if values fall or your finances weaken, so draw and document before you sign a purchase contract.
4. Draw into your own account. Keep the closing documents, the draw confirmation, and the bank statement showing the cash arrive. Underwriters trace large deposits.
5. Ask the DSCR lender how it treats the money. This is the decision point. More on it below.
6. Run DSCR on the new property only. A HELOC secured by a different property normally sits outside the ratio.
7. Treat down payment, closing costs, and reserves as separate pots. A lender may accept borrowed funds for one and not another. Ask about each.
One detail from the investment-line side matters here. On the investment lines Lendmire places, at least 75% of the line is drawn at closing. Pricing floats and never converts to fixed. So you carry a payment on most of the line from day one, whether or not you need all of it.
Which Property Secures the Line?
The line sits on something you already own, and the occupancy of that property sets the ceiling. A line on your primary home gives you far more room than a line on an existing rental.
| Factor | Line on primary home | Line on existing rental |
|---|---|---|
| Max CLTV in the network | Up to 90%, only at 720+ | 70% |
| Credit floor | 600 program floor | 700 minimum |
| Line size | $25,000 to $750,000 | Up to $500,000 |
| Draw structure | 3-year or 5-year draw options | 5-year draw, 25-year repayment |
| Collateral at risk | Your home | Your rental |
Market surveys report that equity lines on investment properties often carry tougher standards than primary-home lines, and Benzinga notes they can cost more. The network figures above are the ones that apply to files Lendmire places. Credit above 700 on an investment line buys eligibility, not extra leverage, because 720 and 700 both reach the same 70% ceiling.
Valuation is usually light on the investment side. Because that line caps at $500,000, it typically uses an automated valuation instead of a full appraisal. A borrower can still request one.
Some properties are simply not offered. Manufactured homes, log homes, and commercial or mixed-use properties fall outside these line programs. Manufactured homes, log homes, and barndominiums are also not offered under the network’s DSCR programs.
Will the DSCR Lender Accept Borrowed Down Payment Money?
It depends on the program, and that is the single most important question before you draw. Across the wholesale network, DSCR lenders treat borrowed funds in one of three ways. Some accept documented secured borrowing. Some cap the borrowed share. Some require a minimum of your own unborrowed funds.
The most commonly accepted form is a documented draw against a property you already own, with a clean paper trail. Money with no traceable source is a different story. So is cash from credit cards or personal loans. Expect those to be refused or questioned hard.
A plan that is 100% borrowed can fail on this rule alone. The same goes for reserves. Reserves are the months of payments a lender wants you to hold in the bank after closing. They commonly run around six months of PITIA (principal, interest, taxes, insurance, and HOA dues). The count moves with lender, leverage, loan size, and transaction type. Many lenders want that pot funded with your own money, which is exactly why a HELOC draw that preserves your savings can help.
Lenders see the HELOC on your credit report. Even though DSCR does not formally compute a debt-to-income ratio, some lenders still factor the line’s payment into their view of your overall debt. Treat that as a possibility, not a rule, and ask.
What Does the Cash Flow Look Like With Both Loans?
The DSCR ratio will look better than your real cash position, because it counts only one of your two loans. Run the numbers this way.
Picture an investor buying a rental on a purchase at 75% LTV, so 25% down. The rent clears roughly 1.2x against the new loan’s full payment. On the file, that looks comfortable. Now add a HELOC that covers the whole down payment, with most of the line drawn at closing and interest-only payments. The rent now has to cover the first mortgage and the line. Blended coverage can slide to around 1.00x or below, even though the file’s own ratio still reads 1.2x. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
This is why an effective leverage figure near 100% deserves respect. You have put none of your own cash in, and the property carries all the debt.
Two more points keep the math honest:
- Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, capital expenses, and the HELOC payment all sit outside the calculation.
- Coverage thresholds are program-specific. A 1.00 coverage floor is where many select programs start. A separate path through select lenders in the network takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
Down payment size also interacts with the ratio. A larger down payment lowers the loan payment and can lift DSCR. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
On purchase leverage, most files land at 75% to 80% LTV, which means 20% to 25% down. Select programs reach 85% LTV, or 15% down, with roughly a 700-plus score. That can shrink the amount you need to borrow in the first place. Lendmire’s piece Using HELOC For Down Payment On Investment Property walks through the same trade-off from the borrower’s side.
Where Does the General Rule Break?
The general rule is that a HELOC on property you own can fund the down payment. These named edge cases are where it stops working.
Properties held in an LLC. Investment lines require the borrower to hold title individually or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on the line. A rental already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead. The new rental can still be titled in an LLC on the DSCR side, subject to lender program eligibility.
A line on the property you are buying. You cannot use a HELOC on the subject property to fund its own down payment. The line needs existing collateral.
Credit score timing. A new line adds an inquiry and utilization. That can shift your score for a while. It matters if you sit near a program floor. Most DSCR programs want around 660, a 620 floor exists in parts of the network, and 700-plus unlocks the strongest leverage tiers.
Exposure limits. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
Availability. Lendmire arranges these lines in 16 full-service states. That is narrower than its DSCR footprint of 41 markets, including Washington, D.C. A borrower in a DSCR market may still need another route to cash.
The draw-period cliff. Market guides describe a typical 10-year draw before principal-and-interest repayment begins. On the investment lines Lendmire’s network places, the structure is a 5-year interest-only draw followed by a 25-year fully amortizing repayment. Either way, the payment rises when the draw ends. Plan your exit before it does: pay down from rent and savings, run a cash-out refinance on the new property after seasoning, or sell.
What Can Go Wrong?
Collateral risk comes first. The CFPB warns that if you fall behind or cannot repay on schedule, you could lose your home. A line on your primary residence puts the house you live in behind a business purchase.
Rate movement comes second. HELOC pricing is variable, and rent is fixed by a lease. The CFPB’s HELOC booklet lists the index, margin, adjustment caps, and draw and repayment periods as the items to compare. Read those before you sign.
Three other risks stack on top:
- Vacancy. A vacant month leaves both payments uncovered.
- Two properties at stake. If the rental struggles, the collateral property is exposed too.
- Qualification drift. The DSCR lender sees the new line as a liability, and the HELOC lender can freeze a line if your finances change.
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.
The stronger play for many buyers is a smaller draw plus some of their own cash, which keeps the mix of borrowed and unborrowed money easier for a lender to accept. A fully borrowed down payment can work, but “can work” and “works on this lender’s program” are not the same thing.
HELOC vs. the Alternatives
A HELOC is one of several ways to produce the down payment. Which one fits depends on where your equity sits and how much you want to keep unencumbered.
| Option | Best when | Watch-out |
|---|---|---|
| Savings | You have idle cash beyond reserves | Drains your liquidity |
| HELOC on primary | You hold big primary-home equity | Home becomes collateral |
| HELOC on a rental | You have equity in an individually held rental | 70% CLTV ceiling, $500,000 cap |
| DSCR cash-out refinance | The rental is held in an LLC, or you want a fixed term | Up to 75% LTV on standard rentals (70% on short-term-rental collateral), about 6 months of seasoning |
| Higher-leverage purchase | You want less cash down | Select programs, roughly 700+ score |
A cash-out refinance is a different loan on an existing rental, so it follows DSCR rules instead of line rules. The term spine there is the 30-year fixed, and select lenders also offer 40-year terms, interest-only periods, and ARM structures.
For a direct comparison of the two products, see Lendmire’s explanation of how a DSCR loan compares with a HELOC on an investment property.
Key Terms Defined
HELOC: An open-end credit line secured by property you own. The CFPB describes it as a line you can borrow against repeatedly, up to a limit set from your equity.
CLTV: Combined loan-to-value. It adds every loan on the property and divides by its value.
Draw period: The stretch when you can borrow from the line, often paying interest only.
DSCR: Monthly rent divided by the property’s monthly payment. It measures whether the rent covers the loan.
PITIA: Principal, interest, taxes, insurance, and HOA dues. It is the full monthly obligation on a property.
Source of funds: The documented origin of your down payment. Lenders trace it.
Seasoning: The waiting period a lender wants before a certain step. For cash-out, it is the time you have owned the property.
Is This the Right Move for You?
It fits you if you hold meaningful equity in a home or individually titled rental, your credit sits at or above 700 for an investment line, and the new rental’s rent covers more than the first mortgage.
It does not fit you if:
- You have no spare cash for reserves.
- You would rather not put your primary home behind the purchase.
- You are counting on the rent alone to carry both payments with no margin.
- The rental you want to borrow against sits in an LLC.

Frequently Asked Questions
Can I use a HELOC for the entire down payment?
Sometimes, but not on every program. Some DSCR lenders accept a documented draw, some cap the borrowed share, and some require a minimum of your own funds. Confirm the rule for down payment, closing costs, and reserves before you draw.
Does the HELOC payment count in my DSCR?
Generally no. DSCR is rent divided by the new property’s payment. A line secured by a different property normally sits outside that ratio. Your real cash flow still pays both, and some lenders glance at overall debt anyway.
Can I open the HELOC after I go under contract?
It is risky. The line has to be open and funded first, since it is secured by property you already own. Lenders can freeze or reduce a line if your finances or the home’s value change.
What is the most I can borrow on an investment property?
Lines on investment properties in Lendmire’s network cap at $500,000 and 70% CLTV, with a 700 minimum score. Primary-residence lines can reach 90% CLTV, only at a 720-or-better profile. Every file is underwritten individually, subject to lender guidelines.
Does clearing 1.00 on DSCR mean the rental is cash-flow positive?
No. The ratio counts only rent against the property’s PITIA. Repairs, vacancy, management, utilities, capital expenses, and any HELOC payment sit outside it.
