The Quick Read: A homeowner can borrow against existing equity to fund the down payment on a second home or rental, and which lender fits depends on the property that secures the line, the combined leverage on that property, and whether the purchase lender accepts borrowed funds. The line is a separate loan from the purchase loan. Each has its own lender, its own rules and its own payment.
- The line is underwritten on you and your equity, not on the new property’s rent.
- Ceilings depend on occupancy: 70% combined loan-to-value (CLTV) on an investment property, and up to 90% on a primary residence or second home at a 720+ credit profile, with lower ceilings, such as 75% CLTV on a primary residence at a 700 profile, for borrowers below that tier.
- The purchase lender decides whether borrowed funds count as a down payment, and that rule varies by program.
- A HELOC does not create a zero-down purchase. It only changes where the cash comes from.
- The HELOC payment sits outside the DSCR calculation, but it still comes out of your real cash flow.
How Does a HELOC Down Payment Work, Step by Step?
A HELOC down payment moves through five steps: choose the collateral, open and draw the line, document the source of funds, underwrite the purchase, and close. The sequence matters because two lenders are involved. Each one reviews a different property and a different set of numbers.
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.
1. Choose the collateral. The line can sit on your primary home, a second home or an existing rental. Each occupancy has different limits, covered below.
2. Open the line and draw. Once the line is open, you draw the cash that will fund the down payment. Confirm with the purchase lender before drawing that the funds will be accepted.
3. Document the source of funds. The purchase lender will want the line agreement, a record of the draw and bank statements showing the deposit.
4. Underwrite the purchase. A DSCR loan is a business-purpose investor loan, designed for non-owner-occupied rentals. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The HELOC payment generally sits outside that ratio.
5. Close. If the purchase lender’s program accepts borrowed funds, the cash is treated as a down payment, nothing more.
Yahoo Finance notes that homeowners can use line proceeds for a down payment or closing costs on a second home or investment property, up to the approved limit. It also cautions that the approach fails for tight budgets or deals already pushing debt-to-income limits.
Which HELOC Lenders Fit a Down Payment Purchase?
The right lender depends on the file: the occupancy of the property securing the line, the credit profile, the leverage needed and how the title is held. Lendmire is a mortgage broker, not a lender. It works with a nationwide network of wholesale HELOC lenders and matches the scenario to the program, so a borrower does not have to apply to one institution at a time.
Large banks and credit unions are the places most borrowers start, and they often price their own customers well. The tradeoff is that each one offers a single set of guidelines. A broker compares several sets at once, which matters when a file sits near a credit tier, a leverage cap or a property-type limit.
Across the network, the occupancy of the collateral changes the numbers more than anything else:
| Collateral | Max CLTV | Credit floor | Max line |
|---|---|---|---|
| Primary residence | 90% at 720+; 75% at 700–719 | 600 | $750,000 |
| Second home | 90% at 720+ | 640 | $500,000 |
| Investment property | 70% | 700 | $500,000 |
The $750,000 maximum on a primary residence applies only at 75% CLTV or lower; at 90% CLTV the line tops out at $500,000.
Several other guidelines apply across these programs, subject to lender guidelines and full file review:
- Line size. Lines run from $25,000 to $750,000. Anything above $500,000 is primary-residence only, caps at 75% CLTV and requires a full appraisal.
- Draw structure. Primary and second-home lines offer either a 3-year interest-only draw with a 17-year repayment, or a 5-year draw with a 25-year repayment. Investment lines use the 5-year structure only. Pricing floats across both the draw and the repayment period.
- Debt-to-income. The ceiling is 50%, or 45% for credit profiles from 600 to 679. Qualifying uses the interest-only payment on the maximum draw.
- Valuation. Lines at or below $500,000 ordinarily use an automated valuation, though a higher CLTV may call for a second look. A borrower can always request a full appraisal.
- Property types. Single-family, 2-4 unit, PUD, townhome and condominium properties are eligible. Manufactured homes, co-ops, condotels and log homes are not.
- Availability. The HELOC program is limited to 16 full-service states, which is narrower than the 41-market DSCR footprint.
The title rule is a common stumbling block for investors. Title must be held by an individual or a revocable living trust. An LLC cannot hold title on the property securing the line. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.
Will the Purchase Lender Accept Borrowed Down Payment Funds?
Acceptance is a program-level policy of the purchase lender. It is not governed by the HELOC lender, and approval of the line does not guarantee the purchase lender will take the cash. Some programs accept a fully borrowed down payment. Others require part of it to be unborrowed or cap the borrowed share. Confirm this before you draw, because a draw cannot be undone once it is made.
Whatever the policy, the purchase itself still has to clear the DSCR program’s own tests. Across the network, most purchase files land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV with a score of roughly 700 or better. Credit floors vary by program: 620 exists in parts of the network, most programs want around 660, and 700+ opens the strongest leverage tiers. Loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders.
On coverage, 1.00 is where many select programs start, and stronger ratios open better terms. A separate select-lender path accepts coverage below 1.00, with leverage and terms adjusted.
Reserves are a separate test. They vary by lender, leverage, loan size and transaction type, and they commonly sit around 6 months of PITIA. Some programs do not count borrowed money toward reserves. A larger down payment lowers the monthly payment and can lift the coverage ratio, but it never erases a leverage cap, a credit floor or a reserve rule. The strongest files clear both tests: enough equity and enough rental coverage. The complete DSCR loans guide walks through those tests in full.
Where Does the General Rule Break?
The general rule is that equity funds the down payment and rent covers the new loan. Several situations break that rule, and each one changes the lender choice.
The collateral is an existing rental. An investment-property line is capped at 70% CLTV and starts at a 700 credit floor. The CFPB booklet on home equity lines also warns that a line’s terms may restrict renting out the home, so read the agreement before pledging a tenant-occupied property.
The second home is personal. A second home you use yourself generally goes through income-based underwriting, where the HELOC payment typically counts in debt-to-income. A rental purchase can go through DSCR, where it generally does not. DSCR is not available for primary residences.
The source property is later sold. The same booklet says a line generally must be paid off in full when the home is sold. A planned sale of the collateral home therefore needs a plan for the balance.
The borrower is large or has history. A borrower can hold at most three lines. A borrower with more than 15 financed properties is not eligible. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On foreclosure history, one wholesale program seasons a foreclosure at 7 years and a short sale or deed-in-lieu at 4 years, while the other declines the history regardless of age. Investment files follow the 7-and-4-year path.
Texas primary residences. A Texas primary is a homestead and caps at 80% combined loan-to-value, so the 90% tier in the table never applies there. The 75% tier at a 700 profile still can.
What Does the Investor Decision Look Like in Practice?
The decision comes down to equity, carry and risk, and all three should be tested before any draw. Start with equity. Yahoo Finance gives the example of a $500,000 home with $300,000 owed, which is 40% equity. In percentage terms, the first mortgage uses 60% of value. A 70% investment-line cap leaves 10 points of value to borrow against. A primary-residence line at 720+ with a 90% ceiling leaves 30 points, still subject to the line-size limit, while a lower-scoring profile, such as 700, reaches a lower 75% ceiling and leaves 15 points.
The same equity supports very different down payments depending on the occupancy of the collateral.
Next, test the carry. Picture an investor with a mortgage on a primary home, a mostly drawn line and a new rental. Three payments now compete for the same income. Benzinga makes the same point: you must be able to carry the primary mortgage, the line and the new mortgage together.
The DSCR ratio compares rent to PITIA only. Clearing 1.00 does not mean positive cash flow, because repairs, vacancy, management, utilities and capital expenses sit outside the calculation. The HELOC payment also sits outside, which makes it easy to forget. Treat it as a real cost when judging the deal.
Finally, weigh the risk. The line is secured by your home, and the CFPB’s overview of home equity lines warns you could lose that home if you fall behind. Pricing floats, so payments can move. Interest-only draws also end. When the draw period closes, the payment steps up into full amortization.
Two alternatives are worth weighing against a line:
- A DSCR cash-out refinance on an existing rental pulls equity from a property whose rent already supports the debt. Cash-out refinances top out around 75% LTV across most of the network, with about 6 months of seasoning commonly expected.
- Lendmire’s article Top HELOC Providers to Fund a Business Purchase or Second Home Down Payment covers how the line works when the purchase is a business.
For a paid-off home, the tradeoffs differ again.
A pure rental purchase usually ends up as a DSCR loan once the down payment is in hand, because the rent, not personal income, carries the qualification. Term structures start with the 30-year fixed. Extended terms such as 40-year and interest-only periods are available through select lenders, and ARM structures exist for investors who want them. DSCR is not offered on manufactured homes, log homes or barndominiums.
Key Terms Defined
HELOC: A revolving line of credit secured by the equity in a home, with a draw period followed by repayment.
CLTV: Combined loan-to-value, which is every loan against the property added together and divided by its value.
Draw period: The stretch of time when you can borrow from the line, usually with interest-only payments.
DSCR: Debt service coverage ratio, which is the property’s monthly rent divided by its monthly principal, interest, taxes, insurance and any HOA dues.
PITIA: Principal, interest, taxes, insurance and association dues, the full monthly housing obligation.
Seasoning: The time funds or a loan have been in place before a lender treats them as established.
Frequently Asked Questions
Can a HELOC cover the whole down payment on a rental?
Sometimes, but that is a purchase-lender decision. Some programs accept a fully borrowed down payment, while others cap the borrowed share or require part of it to be unborrowed. Confirm the rule before drawing, since the draw cannot be undone.
Which property should secure the line, my home or an existing rental?
Your primary residence generally offers the most room. At a 700 credit score it reaches 75% CLTV, and the program allows up to 90% CLTV at a 720+ profile, with amounts up to $750,000 at lower leverage. A rental is limited to 70% CLTV with a 700 minimum credit score. If the rental is held in an LLC, it cannot secure the line at all, and a DSCR cash-out refinance is the route instead.
Does the HELOC payment count against my DSCR?
Not in the ratio, which compares rent to the new property’s PITIA only. It still comes out of your real cash flow, and it counts toward debt-to-income on any later loan that uses personal income. A line under this network’s guidelines is qualified on the interest-only payment calculated on the maximum draw.
Does the credit score decide which HELOC lender fits?
It sets the ceiling and the available tiers. The network’s floor is 600 for primary residences, 640 for second homes and 700 for investment properties. Reports can be no more than 90 days old at closing. Housing-history and tradeline standards also vary by program.
Is a HELOC the only way to fund a down payment from equity?
No. A home equity loan, a DSCR cash-out refinance on an existing rental, or savings can fill the same role. The right choice turns on how much equity remains, how the funds will be used and which payment structure the investor can carry.
