The Quick Read: An investment property HELOC can fund a portfolio down payment, but two separate lenders must both agree: the line lender, which on Lendmire’s network requires a 700 credit score, caps combined leverage at 70% and limits the line to $500,000, and the purchase lender, which decides whether borrowed funds count as down payment. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
- On an investment property, the line is capped at 70% combined loan-to-value (CLTV) and $500,000, with a 700 minimum credit score.
- The line only puts cash in your account. A separate purchase loan, often a DSCR loan, still sets its own leverage, credit and reserve rules.
- On most DSCR files the line payment is not part of the new property’s coverage ratio, yet it is still real money leaving your pocket.
- Confirm with the purchase lender first whether borrowed funds count, in what share, and with what paperwork.
What Is an Investment Property HELOC, and Why Use One for a Down Payment?
A HELOC is a revolving line secured by real estate. An investment property HELOC is secured by a rental you already own rather than your residence. Investors use the cash as the down payment on the next purchase, which turns trapped equity into acquisition capital without selling anything.
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 strategy is popular because a rental purchase typically needs real cash up front. Most DSCR purchase files land at 75%–80% loan-to-value, which means 20%–25% down. Select high-leverage programs reach 85% LTV (15% down) with a score of roughly 700 or better. Scaling a portfolio therefore means finding that cash repeatedly.
Here is the tradeoff. Borrowing the down payment leaves you with little or no equity in the new property on day one. For an investor with strong cash reserves and a high-coverage property, that is manageable. For an investor stretching on every deal, it is closer to 100% financing, and the stress shows up in the first vacancy.
Key Terms Defined
HELOC: A revolving line of credit secured by property, with a draw period followed by a repayment period.
CLTV: Combined loan-to-value, meaning all liens on the property plus the new line, divided by the property’s value.
DSCR: Debt service coverage ratio, which compares a property’s monthly rent to its monthly principal, interest, taxes, insurance and any HOA dues.
Seasoning: The length of time funds or a loan have been in place before a lender counts them.
Borrowed funds: Down payment money that came from a loan rather than your own savings.
Reserves: Liquid cash a lender wants you to hold after closing, commonly measured in months of the property’s monthly obligation.
What Does the Line Lender Require?
On an investment property, the network’s line lenders require a 700 minimum credit score, a maximum 70% CLTV, and a maximum line of $500,000. Those limits apply on top of each other, so whichever bites first sets your usable line.
Both the 720 and 700 credit tiers reach the same 70% CLTV on an investment property. Credit above 700 therefore buys you eligibility, not extra leverage, and 700 is a hard floor with nothing beneath it.
Several other requirements shape the file:
- Debt-to-income: The maximum is 50%. The line is qualified on the interest-only payment calculated on the maximum draw, not on the amount you plan to use.
- Credit report: The score model keys to the primary wage earner, and the report must be no more than 90 days old at closing.
- Credit events: A bankruptcy needs 4 years of seasoning from discharge or dismissal. Investment files follow a 7-year path for foreclosure and a 4-year path for a deed-in-lieu, pre-foreclosure or short sale.
- Line size: Lines run from $25,000 to $750,000 in general. On an investment property, the line stops at $500,000.
- Lien position: The line can sit in first or second position.
- Structure: Investment lines run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. At least 75% of the line is drawn at closing. The payment floats and does not convert to a fixed schedule.
- Valuation: Because an investment line tops out at $500,000, it falls in the automated valuation lane. A traditional appraisal is commonly not required, though a borrower can request one.
NerdWallet reports that lenders in the wider market commonly want 720 or better credit and that many cap leverage below 70%. The network figure for an investment property remains 700 credit and 70% CLTV. Subject to lender guidelines, that is the number to plan around.
How Do You Size the Line? A Step-by-Step Model
The usable line is the property’s value times the CLTV cap, minus the balances already on it. The $500,000 cap then limits the result. This arithmetic is simple, and it is worth doing before you shop for a deal.
Work it in percentages. Say the rental you own carries an existing mortgage equal to 40% of its value. A 70% CLTV cap leaves 30% of the value as the maximum line. If the property is paid off, the whole 70% is available, subject to the $500,000 cap. A property worth more than about $714,000 on a paid-off basis would hit the dollar cap before the percentage cap.
Next, size the need. A portfolio down payment is three separate pots:
1. The down payment itself. On a purchase, this is typically 20%–25% of the price, or 15% on a select high-leverage program.
2. Closing costs. These are separate from the down payment and are sometimes treated differently by the purchase lender.
3. Reserves. These vary by lender, leverage, loan size and transaction type. They are commonly around 6 months of PITIA, and larger loans step up to about 9 months. Borrowed funds are usually excluded from reserves.
That third pot matters most. Many investors size the line to the down payment and forget that the reserves should come from savings. A line that covers all three pots may exist on paper, but the purchase lender may not count it that way.
How Do the Mechanics Work, Step by Step?
The sequence matters more than the product. Following it in the wrong order is how investors end up holding a line that the purchase lender will not accept.
1. Pick the collateral. Either your primary home or a rental you own secures the line. Lines on investment properties are harder to obtain. The White Coat Investor notes that fewer lenders offer them, because lenders see borrowers as more likely to protect their own home than a rental.
2. Ask the purchase lender first. Confirm whether borrowed funds count as down payment, in what share, and what sourcing documents are needed. Do this before opening or drawing anything.
3. Underwrite the line. The line lender reviews equity, credit, DTI and the collateral’s value. NerdWallet adds that an investment-property line may involve more than one appraisal in the wider market.
4. Draw cash into your own account. The line buys nothing. It deposits cash, and that cash becomes the down payment on a separate loan.
5. Document the source. The usual paper trail is the line agreement, the draw statement, and the deposit showing the funds landed.
6. Underwrite the purchase. The purchase loan is reviewed on its own terms, whether that is a DSCR loan or something else.
For the paperwork side of step five, Lendmire’s walkthrough of documenting an investment property HELOC for a portfolio down payment covers what to gather.
How Does the Purchase Lender Treat Borrowed Funds?
Treatment varies by program, and that variation is the heart of the matter. Across the wholesale network, many DSCR programs accept a documented line draw as down payment. Some cap the borrowed share. The strictest want part of the down payment to come from the borrower’s own unborrowed funds.
No true zero-down DSCR purchase exists. A line changes where the down payment comes from. It does not remove the down payment, and every program still applies its own leverage cap, credit floor and reserve rule.
Agency-style conventional loans work differently, and the contrast helps. On a conventional loan, the line’s payment generally counts in the borrower’s debt-to-income ratio. A DSCR loan is not an agency product, so do not assume the conventional treatment carries over in either direction.
Anecdotal evidence in investor communities is mixed. One BiggerPockets thread shows an investor saying lenders do not like to see borrowed funds. That is a single, dated conversation and not a rule. It is, however, a reason to ask before you draw.
What Does the DSCR Calculation Actually See?
DSCR compares rent to the property’s monthly principal, interest, taxes, insurance and any HOA dues. It does not read your personal debts.
Two cautions follow. First, clearing the ratio is not the same as positive cash flow. Repairs, vacancy, management, utilities and capital expenses all sit outside the calculation. Second, the line payment is still real. A BiggerPockets discussion makes the practical point that the new property needs to carry its own mortgage plus the line, and that a fully borrowed down payment on a 30-year hold is close to 100% financing.
On coverage levels, 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 generally open better pricing and leverage. Credit also matters on the purchase side: a 620 floor exists in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers.
A larger down payment shrinks the purchase loan and can lift the ratio, whether or not the cash is borrowed. It never erases leverage caps, credit floors or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. For the full framework, see the complete DSCR loans guide.
Where Does the General Rule Break?
Several edge cases can end the plan or change it. Each is worth checking before you commit.
Title and vesting. The line must be held by you as an individual or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind or land trusts cannot hold title on the line. This is the sharpest structural difference from a DSCR loan. If your rental already sits in an LLC, you would need to change vesting, or consider a DSCR cash-out refinance on that property instead.
Property type. Single-family, 2–4 unit, PUD, townhome and condominium properties are eligible, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use and agricultural-zoned properties are not eligible. If the source rental is one of those, the plan ends there. Separately, DSCR purchase programs in the network do not offer manufactured homes (single- and double-wide), log homes or barndominiums.
Exposure limits. A borrower is limited to three lines. Depending on the wholesale program, combined exposure across them caps at $2,000,000 or $750,000. A borrower with more than 15 financed properties is not eligible. Large portfolio owners can reach these limits sooner than expected.
Geography. Equity lines are available only in Lendmire’s 16 full-service states, which is narrower than the 41-market DSCR footprint. Some properties are also ineligible if recently listed for sale in a handful of those states.
Prepayment penalties. A common recycling plan is to draw, buy, refinance, repay the line and repeat. If the new loan carries a step-down prepayment penalty, an early refinance can cost real money. One BiggerPockets poster flags the step-down structure as a risk for exactly this exit. That is anecdotal, but the mechanics are sound.
Variable payments. The Consumer Financial Protection Bureau explains that HELOC payments can change even if you draw nothing more, and that they are often significantly higher once repayment begins. In some cases the full balance is due when repayment starts. On an investment line, the 25-year repayment period follows five interest-only years, so the payment can step up noticeably.
Which Investor Profile Should Use This, and Which Should Not?
The strategy suits an investor with substantial equity in an owned rental, a score of 700 or better, and a target property whose rent covers its own payment with room to spare. It also suits someone who wants to move on a deal while keeping personal savings intact for reserves.
It works less well for an investor whose existing properties already run thin. Three loans then stack: the first mortgage, the line and the new rental loan. If any one of them strains, the others feel it. A line on your own home adds a further risk, because the home is at stake, whereas a DSCR loan alone is secured only by the rental.
The decision can flip on a few points. If the purchase lender will not count borrowed funds, the line may not help at all, and a cash-out refinance on the source rental may do the job more cleanly. If the property is held in an LLC, the line is off the table. If you need more than $500,000, an investment line cannot supply it.
What Does the Investor Decision Look Like in Practice?
Picture an investor with two rentals who wants a third. The first step is not applying for a line. It is calling the purchase lender to ask how borrowed funds are treated. The second step is sizing the line against the three pots: down payment, closing costs and reserves. The third step is stress-testing the new property’s rent against its own full payment, then against that payment plus the line’s interest-only payment on the full draw.
If all three checks hold, the investor opens the line, draws, documents the deposit and buys. If the third check is tight, the better move is usually a smaller purchase, a larger unborrowed down payment, or a different funding source.
Two conservative habits help. Keep reserves in savings rather than in borrowed cash. And treat the line as acquisition capital with a plan to repay it, not as permanent leverage.

Frequently Asked Questions
Can HELOC funds count as the down payment on a DSCR purchase?
Often yes, but it depends on the program. Many DSCR programs in the wholesale network accept a documented draw, some cap the borrowed share, and the strictest want part of the down payment unborrowed. Ask the purchase lender before you draw, and keep the line agreement, the draw statement and the deposit record together.
Will the line payment lower my DSCR on the new rental?
On most files, no. The ratio compares the new property’s rent to its own principal, interest, taxes, insurance and HOA dues. Your line payment is not in that calculation, but it still comes out of your cash. Conventional loans treat it differently, because the payment counts in debt-to-income there.
What is the largest investment property line available?
The maximum is $500,000 at 70% CLTV, with a 700 minimum credit score. Larger lines exist only on a primary residence, where they require a full appraisal and a higher credit profile. Available equity is the property’s value times 70%, minus existing liens, and then the dollar cap applies.
Can I use a line secured by a rental held in my LLC?
No. The line must be held by you personally or by a revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title. An investor with an entity-owned rental may need a vesting change or a DSCR cash-out refinance instead.
Can the line cover my reserves too?
Usually not. Borrowed funds are commonly excluded from reserves, which are often around 6 months of PITIA and can rise with loan size. Plan to hold reserves in savings, and confirm with the purchase lender how it treats each of the three pots.
