The Quick Read: The best program for your situation is the one that frees cash from a home you already own, pairs with a purchase lender that accepts borrowed down payment funds, and still leaves your monthly cash flow standing once both payments are due. In practice that means a standalone equity line on your primary home or an existing rental, plus a separate DSCR loan on the new property.
- A home equity line of credit (HELOC) only supplies the down payment. The new property still needs its own loan.
- Across our wholesale network, an equity line on an investment property tops out at 70% combined loan-to-value, with a $500,000 maximum line and a 700 credit minimum.
- Lines on a primary residence or second home can reach higher leverage, but 90% combined loan-to-value exists only at a 720-or-better credit profile.
- Whether the purchase lender accepts borrowed money is program-specific. Ask before you draw.
- Passing the rental coverage test is not the same as positive cash flow. The line payment still comes out of your pocket.
How Does a HELOC-Funded Down Payment Actually Work?
Two loans, two files. The HELOC is judged on you and the equity in the home that secures it. The DSCR purchase loan is judged on the new property’s rent. Neither lender underwrites the other’s loan, and one never replaces the other.
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.
DSCR means debt service coverage ratio. It compares the property’s monthly rent to its monthly PITIA, which is principal, interest, taxes, insurance, and any association dues. For the broader picture, see our complete DSCR loans guide.
The sequence matters more than most investors expect:
1. Open the line first. Get it approved before you make offers. The line is secured by property you already own, never the one you are buying.
2. Ask the purchase lender before you draw. Get the rule on borrowed funds in writing. Ask whether there is a cap on the borrowed share.
3. Draw and park the cash in your own account. The money then shows up as a documented source.
4. Let the funds season. Most purchase lenders want to see borrowed money sitting for a period before it counts toward the down payment. The length varies by lender, so ask for theirs.
5. Close the purchase. The DSCR loan treats the cash as down payment and nothing more.
6. Keep paying both loans. Rent covers the new property. The line payment comes from your own cash flow.
A zero-down DSCR loan does not exist on the target property. The HELOC only changes where the down payment cash comes from.
Key Terms Defined
HELOC: a revolving line of credit secured by a property you own, which you draw from, repay, and draw from again during a set window.
CLTV (combined loan-to-value): all loans secured by the property added together, divided by its value.
Draw period: the stretch when you can borrow from the line, usually with interest-only payments.
Repayment period: the stretch after the draw ends, when you can no longer borrow and payments include principal.
Seasoning: the time borrowed or deposited funds must sit in your account before a lender treats them as your own money.
Reserves: liquid cash a lender wants left in your account after closing, commonly measured in months of PITIA.
What Makes One HELOC Program Better Than Another?
No single program wins for every investor. The best program for your situation depends on which property secures the line, how much leverage you need, your credit tier, and whether the new loan’s lender accepts the money. A broker who shops several wholesale HELOC lenders can match those pieces. That is the main advantage of going through one.
Here is how the main collateral choices compare across our network. Each figure applies only to its own occupancy type and is subject to lender guidelines.
| Factor | Primary home | Second home | Existing rental |
|---|---|---|---|
| Max CLTV | 90% (720+ only) | 90% (720+ only) | 70% |
| Max line | $750,000 | $500,000 | $500,000 |
| Credit minimum | 600 floor | 640 | 700 |
| Draw structure | Two options | Two options | 5-year draw only |
On a second home, the ceiling steps down with credit: 85% CLTV at 680 and 700, 80% at 660, and 75% at 640. A primary-home line above $500,000 needs a credit profile of 700 or better (720 on the 5-year draw, 25-year repayment structure), caps at 75% CLTV, and requires a full appraisal.
Those two draw structures need names. One is a 3-year interest-only draw followed by 17 years of full repayment. The other is a 5-year draw followed by 25 years. Investment-property lines run the 5-year structure only. At least 75% of the line is drawn at closing, and pricing floats through both phases. It never converts to a fixed payment.
That 75% draw has a practical effect. You pay interest on most of the line from day one, even if the down payment needs only part of it. Size the line to the need, not to the maximum.
The percentage math
CLTV caps are easy to misread, so run it with percentages. Suppose your home carries a first mortgage equal to 55% of its value. Under a 70% investment-property cap, the line can add at most 15% of value. Under a 90% cap at 720 or better on a primary home, it could add up to 35%. Either way, the cap covers all liens together.
Who qualifies for the line itself
Debt-to-income (DTI) can run up to 50%. It drops to 45% for credit profiles from 600 to 679. The lender reviews your file on the interest-only payment at the maximum draw, not on the amount you actually take. Lines up to $500,000 usually use an automated valuation instead of a traditional appraisal.
Eligible properties include single-family homes, 2-4 units, PUDs, townhomes, and condos, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered. Title must sit with you personally or in a revocable living trust. An LLC cannot hold title on the line.
That LLC rule is the sharpest difference from a DSCR loan. If your rental is already deeded to an entity, it cannot secure the line without a vesting change. HELOC availability through Lendmire’s network is also limited to 16 full-service states, a narrower footprint than the 41-market DSCR platform.
Primary-Home Line or Rental Line?
Neither is automatically better. The right collateral depends on your equity, your credit, and how much risk you will tolerate.
A primary-home line offers more leverage and a higher ceiling. It also puts the home your family lives in on the line. A line on an existing rental caps at 70% CLTV and needs a 700 credit profile. It keeps the risk on investment real estate, though the rent from that rental still has to carry its first mortgage and the new line payment.
Think about where a bad outcome lands. If the rental portfolio stumbles, would you rather it threaten the investment property or your house? Plenty of investors answer that differently, and both answers are defensible.
Consider this option if the line would sit on a property you already rent out.
Will the Purchase Lender Accept Borrowed Money?
Sometimes. It is the question that decides the whole plan.
Most DSCR purchase programs land at 75% to 80% LTV on a purchase, which means 20% to 25% down. Select high-leverage programs reach 85% LTV with roughly a 700-plus score. Some of those programs accept fully borrowed funds. Others want part of the down payment unborrowed. A few cap the borrowed share. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Down payment, closing costs, and reserves get tested as separate pots. Borrowed money is often accepted for the first two and commonly excluded from reserves. Reserves vary by lender, leverage, and loan size. Around 6 months of PITIA is common, and larger loans typically step up from there.
A bigger down payment lowers the payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Credit tiers shape this too. A 620 floor exists in parts of the network. Most programs want around 660. A 700-plus score opens the strongest leverage tiers.
On the coverage side, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. A fully borrowed down payment can fail on leverage grounds alone, even when the rent looks strong.

A Worked Scenario, in Ratios
Run the numbers on an investor who buys a duplex at 75% LTV. That means 25% down, drawn from a HELOC on the investor’s primary home. The rent clears roughly 1.2x on the new DSCR loan. These are modeled assumptions, not market data. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
On paper, the file looks strong. The DSCR loan sees a 25% down payment and a rent-to-PITIA ratio comfortably above the 1.00 starting point. It does not see the line. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Now look at the real cash flow. The same rent check has to cover the DSCR loan and the interest on the line. Compare that with an investor who put down cash. Both can show the same 1.2x coverage. Only one has two payments to make.
That is why the ratio and the cash flow are different tests. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses all sit outside it. Clearing 1.00 is not positive cash flow. Stress-test the line payment before you draw, not after.
Where the General Rule Breaks
Fully borrowed down payment. That is close to 100% financing across two loans. The rent must carry both. Some programs reject it outright.
HELOC on the rental itself. This is a standalone line on a one-to-four-unit investment property, qualified on the borrower and the equity. Title cannot sit in an LLC. If you want financing tied to the rental’s income instead, ask about a DSCR cash-out refinance.
Paid-off rentals. A line on a free-and-clear rental can fund a package of purchases. The 70% cap and 700 credit minimum still apply.
Bank statement lines. Some files qualify on documented income under the applicable program, subject to lender guidelines. Ask whether the funds are accepted for the purchase.
Frozen lines. Bankrate notes that a significant drop in home values can lead a lender to reduce or freeze the line during the draw period. This is why you draw before trouble starts, not after.
Exposure limits. A borrower is limited to three lines. A borrower with more than 15 financed properties is not eligible.
Listed properties. In certain states, a home listed for sale within the past 60 days is ineligible. Confirm your state before you plan around the line.
Costs and Risks You Should Price In
The line is variable. Experian notes that most HELOCs carry variable pricing, so payments can move with benchmarks like prime. Its general market description is a draw period of up to 10 years followed by repayment that more commonly lasts 20 years. Payments jump once principal comes due. Some lines carry a balloon payment when the draw ends. Our network structures differ: a 3-year draw with 17 years of repayment, or a 5-year draw with 25 years. Investment lines use the 5-year version only.
The collateral risk is real. The CFPB’s HELOC booklet describes a HELOC as a loan secured by your home. It also notes that if you sell, you are generally required to pay the line off in full right away. Selling a rental that secures the line means paying the line first.
The honest cost list:
- The line payment, which comes out of rent or your own pocket.
- Rising payments if pricing moves against you or repayment begins.
- A lien on property you already own.
- Interest on at least 75% of the line from closing.
- Possible freezes or reductions if values fall.
Who Should Skip This
Skip the HELOC route if any of these describe you:
- The new rental only barely covers its own payment.
- You have little cash outside the line.
- The purchase lender rejects borrowed funds.
- The property securing the line sits in an LLC.
- Your plan to repay the line depends on a market that has to cooperate.
Alternatives exist. A cash-out refinance on an existing rental tops out around 75% LTV on standard rentals, with about 6 months of seasoning as the common expectation. It gives you one payment instead of a floating line. A HELOC can be reused after payoff, while a refinance cannot. Many investors weigh reusability against payment certainty. This is a real toss-up, and the answer depends on how fast you plan to repay.
Many investors pay down the line through a later cash-out refinance once the new property is stabilized. That exit plan only works if the new property qualifies at the leverage the refinance needs.
Frequently Asked Questions
Can I use a HELOC on the property I’m buying?
No. The line must be secured by property you already own, and it has to be in place before you need the money. The new property is financed with its own purchase loan.
Does the HELOC payment count against my DSCR?
On most files it does not. DSCR compares rent to the new property’s PITIA. The line payment still hits your real cash flow, and some lenders review your overall debt picture separately.
Can a HELOC cover reserves too?
Usually not. Borrowed money is often accepted for the down payment and closing costs but commonly excluded from reserves. Confirm the rule with the purchase lender before you plan around it.
Can I put a HELOC on a property held in my LLC?
Not through our network. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance instead.
How much equity do I need?
It depends on the property, the credit tier, and your existing liens. On an investment property the ceiling is 70% CLTV, so your first mortgage must leave room beneath that cap. Subject to lender guidelines and full file review.
