The Quick Read: A home HELOC can supply the cash for a rental down payment when the purchase lender accepts documented borrowed funds, the line is approved on its own personal underwriting, and the rental still clears its own coverage test, so the investor needs enough equity at home and enough rent at the property.
- The line and the rental loan are two separate approvals. The line is underwritten to you. The DSCR loan is reviewed mainly on the property’s rent against its monthly obligation.
- Lenders in Lendmire’s wholesale network split into three camps on borrowed funds. Some accept documented line proceeds, some cap the borrowed share, and some want part of the down payment fully unborrowed.
- Borrowed cash never lifts leverage caps. Most purchase files land at 75%-80% LTV, and select programs reach 85% LTV at roughly a 700+ score.
- The line’s payment sits outside the coverage ratio, but it still comes out of your pocket every month. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
What Does Using a Home HELOC as a Down Payment Actually Mean?
A home equity line of credit is an open-ended line secured by a home you already own. You borrow against the equity, which is the home’s value minus what you owe on it. Opendoor’s HELOC explainer describes the same pattern: a draw period when you can borrow, then a repayment period when you can’t.
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.
Using it for a rental means you draw cash from your own house and put that cash toward the purchase of an investment property. The line can’t buy the rental. It only borrows against a property you already hold.
That creates two lenders and two files:
- The line lender looks at you. It reviews credit, equity, existing liens, and debt-to-income.
- The purchase lender looks mostly at the rental. A DSCR loan compares monthly rent with the full monthly obligation: principal, interest, taxes, insurance, and any HOA dues.
Neither approval guarantees the other. Strong rent can’t fix thin equity at home, and strong equity can’t fix weak rent. The strongest files clear both tests.
How Underwriting Treats the Money, Step by Step
Underwriting follows a fixed order, and the order matters. The investor opens the line first, then moves the cash, then documents it, and only then qualifies the rental on its income.
1. Ask the purchase lender or broker before drawing. Confirm that borrowed funds are acceptable and what documents are needed. Programs differ, and this one question prevents most failed files.
2. Open the line before going under contract. You can’t open a line on a property you haven’t bought yet, so the line has to exist before the contract does.
3. Size the line. Multiply the home’s value by the combined loan-to-value cap, then subtract existing liens. Combined loan-to-value (CLTV) counts every lien on the home together.
4. Draw and move the cash into your own account. Keep the statements. A typical package is the line’s closing documents, the draw confirmation, and bank statements showing where the money landed.
5. Let the funds season if the lender asks for it. One investor on BiggerPockets advised drawing early enough that the deposit doesn’t sit alone in the most recent statement period. That is one investor’s experience. The purchase lender’s own rule governs.
6. Qualify the rental on rent against payment. The line’s payment is not in that ratio.
A modeled sizing example
Run the numbers in percentages of value. Say the first mortgage on your home sits at 50% of its value and your credit profile supports an 80% combined cap. That leaves room equal to 30% of the home’s value.
Now say the rental is priced near the home’s value and the purchase needs 25% down. The down payment uses 25 of those 30 points. Closing costs would take most of the remaining 5, and none is left for reserves. These are modeled assumptions, not market data. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What the line side looks like in the network
On a primary residence, lines reach up to 90% CLTV, and only at a 720-or-better credit profile. The program floor for credit is 600. Debt-to-income tops out at 50%, and it falls to 45% for profiles between 600 and 679. The line is qualified on the interest-only payment calculated on the maximum draw, so a large line can squeeze your ratio even if you draw less.
At least 75% of the line is drawn at closing. That detail is easy to miss. If the line is sized far above the down payment you need, you carry a large balance from the start. Size the line to the need.
Primary residences and second homes offer two draw structures. One is a 3-year interest-only draw followed by a 17-year repayment. The other is a 5-year draw followed by a 25-year repayment. Pricing floats during both phases and never converts to fixed. A line above $500,000 is primary-residence only, needs a 700-or-better credit profile (720 on the 5-year-draw structure), caps at 75% CLTV, and requires a full appraisal. Lines at or below $500,000 usually use an automated valuation instead. All of this is subject to lender guidelines and full file review.
Will the Purchase Lender Accept Borrowed Funds?
It depends on the lender. Across Lendmire’s wholesale network, programs fall into three camps on borrowed down-payment money:
- Accept documented proceeds. The money counts if the paper trail is clean.
- Cap the borrowed share. Only a portion of the down payment can come from the line.
- Require some fully unborrowed cash. A slice of the down payment has to come from savings or other owned funds.
A broker with many lenders can often steer a file toward the camp that fits. That is the practical advantage of placing the loan through a network rather than a single lender’s menu.
Down payment and reserves are separate pots. Borrowed money may cover one but not the other. Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around 6 months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about 9 months.
Here is what the DSCR side of the file looks like, framed as typical ranges:
| Factor | Typical network range |
|---|---|
| Purchase LTV | 75%-80% (20%-25% down) |
| High-leverage purchase | Select programs to 85% LTV |
| Credit score | 620 floor in parts; most want about 660 |
| Strongest tiers | 700+ |
| Loan size | Up to $3,000,000 on standard programs |
A bigger down payment lowers the monthly obligation and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. For coverage, 1.00 is where select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage. For a fuller look at these moving parts, see the complete DSCR loans guide.
Which Property Should Secure the Line?
The line can sit on your home or on an existing rental, and the rules differ sharply. A home line usually allows more leverage and more flexibility. A rental line is capped lower and has a tougher credit floor.
| Factor | Home (primary residence) | Existing rental |
|---|---|---|
| Max CLTV | Up to 90% at 720+ | 70% |
| Max line | Up to $750,000 | $500,000 |
| Credit floor | 600 program floor | 700 |
| Draw structure | 3-yr or 5-yr draw | 5-yr draw, 25-yr repay |
On an investment property, a 720 and a 700 score both reach the same 70% CLTV. Credit above 700 buys eligibility, not extra leverage. Because the line caps at $500,000, an investment line stays in the automated-valuation lane and commonly closes with no traditional appraisal.
The tradeoff is risk. A line on your home puts your home on the hook for a rental purchase. A line on a rental keeps that risk off your residence but gives you less borrowing room. Lendmire’s explainer How to Use a Rental HELOC for the Next Down Payment and Still Qualify covers the rental-secured path in detail.
Will the HELOC Payment Hurt You at Qualification?
On a DSCR loan, the line’s payment does not enter the coverage ratio. That ratio compares rent with the rental’s own obligation. A conventional investment loan works differently. The same investor thread on BiggerPockets notes that a conventional underwriter would count the line’s minimum payment in your debt-to-income, so you’d carry three debts. A DSCR file avoids that test on the rental loan.
The line lender still tests you. Its 50% debt-to-income ceiling, run on the interest-only payment at the maximum draw, is the real gate on the personal side.
The stacked-payment test
Clearing the coverage number does not mean the property makes money. Run the numbers on a modeled case. Say rent covers the full monthly obligation at 1.20x. That passes. But the 0.20 of cushion above the payment is the only pool that has to absorb the line’s payment, repairs, vacancy, management, utilities, and capital costs. A BiggerPockets thread on this same question makes the same point: the rent has to carry both the purchase loan and the line.
If the rental is at or near 1.00x, the line’s payment comes straight out of your other income. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Stacking a second payment onto a rental that is already thin is a risk worth sizing carefully.
Payment shock
Line payments can move even when you draw nothing more. The CFPB’s HELOC brochure notes that variable-rate plans can change your payment, and that some plans require full repayment when the draw period ends. The CFPB’s HELOC page gives a 10-year draw period as an example. Moving from interest-only into repayment is the point where payments can jump materially.
Plan the payoff before you draw. Investors usually choose one of two routes: pay the line down from cash flow, or refinance the rental after improving it and use the proceeds to retire the line. The cash-flow route is slow. The refinance route works only if the rental reaches the value and coverage the lender needs. Cash-out refinances on standard rentals top out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation.
Experienced brokers see the same pattern often. Borrowers clear the coverage test on the rental and then discover the line’s payment was the real constraint. Running the line payment against your own budget before you draw prevents that surprise.
Where the General Rule Breaks
The steps above cover most files. These cases change the answer.
The home is titled in an LLC. A line requires title held by you personally or in a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts can’t hold title on a line. A home already deeded to an LLC needs a vesting change first, or a DSCR cash-out instead. The rental purchase itself can be made to an LLC-titled borrower, subject to lender program eligibility.
The home is paid off. A free-and-clear home can support a strong line, but the money isn’t free. The home is the collateral.
Self-employed borrowers. A line can qualify on documented income under the applicable program, subject to lender guidelines. Business bank deposits need a 680 minimum for the deposit analysis. On an investment line, the 700 floor binds first.
Exposure limits. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on one structure and $750,000 on the other. A borrower owning more than 15 financed properties is not eligible.
Property type. Condos, including non-warrantable ones, townhomes, PUDs, and 1-4 unit properties are eligible on the line side. Manufactured homes, co-ops, condotels, log homes, commercial, and mixed-use are not. On the DSCR side, manufactured homes, log homes, and barndominiums are not offered.
Short-term rentals. Purchases run up to 75% LTV with a 640+ score, about 12 months of hosting history, and a 1.00 coverage floor. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure-family events follow a 7-year and 4-year seasoning path on investment files.
Footprint. Home equity lines run in 16 full-service states, narrower than the 41-market DSCR footprint, which includes Washington, D.C. A handful of states apply their own caps on primary-residence lines, so your ceiling can sit lower than the headline figure.
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.
Who Should Do This, and Who Should Skip It?
The plan fits an investor with real home equity, a stable personal income, and a rental that clears coverage with room to spare. It also fits someone who already has a payoff plan.
It is the wrong tool in a few cases. The stronger play might be a smaller purchase or more savings if the numbers pencil only when every assumption goes right. The same goes for a rental that sits at 1.00x or below with no cushion. A borrower who can’t absorb the line’s payment during vacancy should rethink the structure.
Common mistakes to avoid:
- Drawing before asking the purchase lender whether borrowed funds count.
- Sizing the line well above the need, then carrying the balance.
- Treating a passing coverage ratio as proof the deal makes money.
- Forgetting reserves, which borrowed funds may not cover.
- Ignoring that a variable payment can move after the draw period ends.
Key Terms Defined
HELOC: A revolving line of credit secured by a property you already own, with a draw period followed by repayment.
CLTV (combined loan-to-value): All liens on the property added together and divided by its value.
DSCR: Monthly rent divided by the full monthly obligation of principal, interest, taxes, insurance, and any HOA dues.
PITIA: The full monthly obligation on a property: principal, interest, taxes, insurance, and association dues.
Reserves: Liquid funds held after closing, separate from the down payment.
Source of funds: The documented origin of the cash used for a down payment.
Frequently Asked Questions
Do I need to tell the purchase lender the down payment came from a line?
Yes, because the lender reviews where the cash came from. The documents show it either way, since the draw and the transfer appear on your statements. Raising it up front lets a broker place the file with a lender that accepts documented borrowed funds.
Can the HELOC also cover my reserves?
Often not. Down payment and reserves are separate pots, and some lenders accept borrowed money for one but require reserves from your own liquid funds. Reserves commonly run around 6 months of PITIA, though the figure varies by lender, leverage, loan size, and transaction type.
Does a larger down payment from the line improve my DSCR?
It can, because a bigger down payment shrinks the loan and its payment. It does not override leverage caps, credit floors, reserve rules, or property eligibility. A higher ratio can improve pricing and leverage, but only within those limits.
What happens if the rental sits vacant?
The line’s payment still comes due, and it comes out of your other income. The coverage ratio does not account for vacancy, repairs, or management. Investors who stack a line on a thin rental should hold extra liquidity.
Can an LLC-owned home secure the line?
No. The home must be titled in your name or a revocable living trust. A home already in an LLC needs a vesting change, or a DSCR cash-out refinance as an alternative route.
