Best HELOC Program to Fund a Down Payment on the Next Home

The Quick Read: The right program depends on which property secures the line. Combined loan-to-value ceilings are lower on an investment property than on a primary residence or second home, and the highest ceiling requires a strong credit profile. A line only supplies cash, so the purchase loan is a separate file that must accept borrowed funds and clear its own tests. Open the line before you shop, and size it to the cash you need.

• Occupancy sets the ceiling. Investment-property lines need a 700 minimum score and cap at $500,000. Second-home lines start at a 640 score, and primary-residence lines start at 600.
• Most of the line is drawn at closing. At least 75% of the line is funded on day one, so you pay on most of it immediately. Pricing floats and never converts to fixed.
• Borrowed funds and reserves are different tests. Many purchase programs accept borrowed money for the down payment and closing costs, but borrowed money generally does not count toward reserves.
• The new rental’s coverage ratio ignores the line’s payment. Your bank account does not.
• There is no zero-down DSCR purchase. Plan on roughly 15% to 25% down, depending on credit and program.

Key Terms Defined

HELOC: a revolving credit line secured by a home you already own, where you borrow only what you need.

CLTV (combined loan-to-value): every loan against the home, added together, divided by the home’s value.

Draw period: the stretch when you can borrow, usually paying interest only, followed by a repayment period that includes principal.

DSCR (debt service coverage ratio): the property’s monthly rent divided by its monthly payment, the number a rental purchase lender checks.

PITIA: principal, interest, taxes, insurance, and any association dues, which together make up that monthly payment.

Reserves: liquid money left after closing, counted in months of PITIA.

Seasoning: the waiting period a lender wants between two events, such as buying a property and cashing out on it.

Lien position: whether a loan sits first or second in line to be repaid if the property is sold or foreclosed.

How a HELOC Funds the Down Payment on the Next Home

A HELOC turns equity in a home you already own into cash, and that cash goes toward the next purchase. It is two separate transactions: a line on the old property, then a purchase loan on the new one. Each has its own lender and its own underwriting.

Here is the sequence that works across the wholesale network Lendmire places files with:

1. Pick the collateral. The line can sit on a primary residence, a second home, or an investment property. Each has its own credit floor and leverage ceiling, covered in the next section.

2. Open the line before you shop. Approval comes first, because a purchase contract signed before the line closes puts you in a bind if the line comes back smaller than expected. A line can also be reduced if the home’s value drops, so draw before you contract.

3. Draw the cash and keep the paper trail. The purchase underwriter will want the loan terms and the draw records to see where the money came from.

4. Let the purchase lender decide about borrowed funds. This is a separate gate from the line’s approval. Many programs accept borrowed money toward the down payment and closing costs. A few cap the borrowed share, and the strictest want part of the down payment unborrowed.

5. Run the coverage test on the new property. The purchase lender checks whether the rental’s income covers its own payment. The line’s payment is not part of that ratio.

6. Plan for the step-up. Investment-property lines on this network run a 5-year interest-only draw followed by a 25-year fully amortizing repayment. The payment jumps when the draw ends. Primary and second-home lines have a second structure, a 3-year draw with a 17-year repayment. General-market lines often carry a ten-year draw, according to Yahoo Finance, so a shorter runway here is a real difference to plan around.

The drawn-at-closing rule changes how you size the line. At least 75% of the line is funded at closing on both structures, so a line opened for flexibility starts costing you immediately. Later draws are allowed, generally with a $1,000 minimum, but the cleanest plan is a line sized to the cash you need now.

What Makes One HELOC Program the Right Fit?

The best program for your situation is the one whose occupancy tier, leverage ceiling, and credit floor match the property you are borrowing against. Brokers see the same pattern repeatedly: borrowers shop for the highest ceiling, then discover that ceiling belongs to a different occupancy type than theirs.

Those ceilings come with strings. On a primary residence, 90% CLTV applies only at 720 or better and only on lines up to $500,000. Lines above $500,000 are available on primary residences only, cap at 75% CLTV, and require a full appraisal. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal, though higher leverage can trigger a second valuation.

Other parameters worth knowing before you apply:

• Debt ratio: a 50% maximum, or 45% for credit profiles from 600 to 679, calculated on the interest-only payment at the maximum draw.
• Credit scoring: a single-bureau model keyed to the primary wage earner, with a report no more than 90 days old at closing.
• Property types: single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
• Title: an individual or a revocable living trust must hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot.
• Exposure: a borrower is limited to three lines, and anyone owning more than 15 financed properties is not eligible.
• Availability: Lendmire’s HELOC placements cover 16 states, a narrower footprint than its DSCR investor lending across 41 markets, including Washington, D.C.

Some states add their own rules, such as waiting periods or CLTV caps tied to credit profile. Every figure here is subject to lender guidelines and full file review, and none of it is a commitment to lend.

How Does the Purchase Lender Treat Borrowed Funds?

Across most programs in the network, a DSCR purchase lender accepts HELOC money for the down payment and closing costs with documentation, but not for reserves. The ratio itself compares rent to the property’s payment, so your personal debt ratio generally is not part of that review.

That is the sharpest contrast with the line itself. The line is underwritten on you: your income, your debt ratio, your credit. The rental purchase loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Two different tests, two different files. Self-employed borrowers whose tax returns understate their income can look at whether a bank statement HELOC can cover the down payment on your next home.

DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. If the next home is your own residence, the purchase loan is an owner-occupied loan, and those lenders count the line’s payment in your debt ratio. This article’s spine is the investor path, which is covered in depth in the complete DSCR loans guide.

For investor purchases, here is what the numbers usually look like:

• Leverage: most files land at 75% to 80% LTV on a DSCR purchase of an investment property, which means 20% to 25% down. Select programs reach 85% LTV on a purchase (15% down) with roughly a 700+ score.
• Coverage: 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
• Credit: a 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
• Reserves: commonly around 6 months of PITIA, though they vary by lender, leverage, loan size, and transaction type. Larger loans step up, often to about 9 months.

Clearing 1.00 does not mean the property produces positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it.

A Worked Example in Percentages

Say you own a primary residence with a first mortgage equal to 40% of its value. Assume a 720 score, which opens a 75% CLTV tier. Using that tier as the modeled assumption, the line has room up to 35% of the home’s value, if the amount fits under the line cap.

Now say you buy a rental at 75% LTV on a DSCR purchase, meaning 25% down. If the rental is priced near your home’s value, the equity available in your home covers the down payment and closing costs. It does not cover reserves, which must come from your own liquid funds. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

The rental clears roughly 1.2x on rent alone. That sounds comfortable, but 1.2x only means rent covers the rental’s own PITIA with a modest cushion. You are now carrying three obligations: the first mortgage on your home, the line, and the rental loan. The line’s payment steps up when the draw period ends, and its pricing floats throughout. If the rental sits vacant during a renovation, the line’s payment comes straight out of your pocket.

This is why the strongest files clear both tests: enough equity to fund the cash, and enough rental coverage to carry the whole stack.

Where the Rule Breaks: Edge Cases

The standard plan breaks in a handful of predictable places.

The home is listed or about to be. In several states, a property listed for sale, or listed within the past 60 days, is ineligible for the line. Open the line before you list, not after.

The home becomes a rental. The CFPB’s HELOC booklet notes that renting out the home may be prohibited by the line’s terms, and that selling the home generally requires paying the line off in full. It also says a lender can freeze or reduce a line if the home’s value drops significantly. Read the line agreement before you build a plan around converting the house.

The recycle strategy. Some investors draw the line, buy, run a cash-out refinance on the new property, and repay the line. Step-down prepayment penalties are common on DSCR loans, so an early refinance can cost real money. Cash-out refinances on standard rentals top out around 75% LTV, with about 6 months of seasoning as the common expectation. That is a long wait if the line’s payment is already stepping up. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Value-add versus stabilized. The recycle plan makes sense when a renovation raises value enough to support the refinance. On a clean, stabilized buy-and-hold with no refinance exit, the line becomes long-term variable-priced debt, and a lot of investors underestimate that.

LLC-held rentals. A property already deeded to an LLC can’t secure the line. The fix is a title change or a DSCR cash-out refinance instead, subject to program terms.

Fully borrowed down payments. Some programs accept a down payment funded entirely by borrowed money, which creates roughly 100% financing across two loans. Rent has to carry both payments, and the borrowed money still cannot count toward reserves.

Interest deductibility. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.

The CFPB’s HELOC overview also warns that you could lose your home if you fall behind on the line. That is the real stake: a missed line payment puts the old home at risk, not the rental.

Line, Cash-Out, or Savings: Which Source Fits?

A HELOC is one of three common ways to source the down payment. The alternatives depend on whether you own a rental with equity and how you hold title.

A DSCR cash-out refinance on an existing rental is explicitly accepted as a down payment source on a new purchase. It uses the rental as collateral rather than your home, and it avoids a second payment on the primary residence.

Savings avoid the second payment altogether, but they can leave you short on reserves. A line lets you keep cash in the bank for the cushion while the borrowed money covers the down payment.

Checklist Before You Apply

Ask the line lender:

• Does the ceiling for my occupancy type and credit profile fit the cash I need?
• What share of the line is drawn at closing, and what does the payment do when the draw ends?
• Does the agreement restrict renting the home or require payoff on sale?
• Is the property or its title eligible, given any LLC, trust, or listing history?

Ask the purchase lender:

• Do you accept borrowed funds for the down payment, and is there a cap on the borrowed share?
• How many months of reserves do you want, and what counts toward them?
• What documents do you want for the draw?
• Is there a prepayment penalty if I plan to refinance early?

A broker that shops multiple wholesale lenders can ask these questions on your behalf and match the answers to the file before you commit.
