Best HELOC Program to Cover the Down Payment on a Home

The Quick Read: The right program is the one that is approved, drawn, documented, and seasoned before the purchase loan is reviewed, sized to the full down payment plus closing costs, and paired with a rental that covers its own payment, because the purchase lender’s rule on borrowed funds decides the outcome. No single line wins for every borrower. Occupancy, credit profile, and combined leverage change which program fits.

• On an investment-property line, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit score.
• On primary-residence and second-home lines, the ceiling reaches 90% CLTV, and only at a 720 or better credit profile.
• At least 75% of the line is drawn at closing, so oversizing the line costs real money.
• Borrowed funds often count toward the down payment and closing costs. They often do not count as reserves.
• A DSCR purchase is judged on the new rental’s coverage. The line’s payment sits outside that ratio but inside your real cash flow.

What Is the Best HELOC Program to Cover the Down Payment on a Home?

The best HELOC program for you depends on the property securing the line, your credit profile, how much leverage you need, and what the purchase lender will accept. Lendmire is a mortgage broker. It places home equity lines through select wholesale partners and does not lend directly. That distinction shapes the advice here. A broker can match a file to the program that fits it, and no single lender’s menu can do that.

The core idea is simple. Equity in one property becomes cash for the down payment on another. Yahoo Finance notes that homeowners can use equity in a primary residence toward a down payment on a vacation home or investment property. The line can also cover closing costs, up to the approved limit.

Here is the catch. The line is only half the transaction. A strong line paired with a purchase program that rejects borrowed funds goes nowhere. Strong rental coverage paired with a line that never gets approved goes nowhere either. The strongest files clear both tests: enough equity and enough rental coverage.

If you hold the deal in an LLC, pay attention now. A line like this must be held in your personal name or a revocable living trust. The DSCR purchase can sometimes go into an entity, subject to lender program eligibility. That mismatch is common, and it is covered below.

Key Terms Defined

HELOC: A revolving line of credit secured by property you own, with a draw period followed by a repayment period.

CLTV: Combined loan-to-value, which adds every loan secured by the property and divides by its value.

Seasoning: The time borrowed or deposited funds must sit in your account before a purchase lender treats them as usable.

DSCR: Debt service coverage ratio, which compares a rental’s monthly rent to its monthly payment of principal, interest, taxes, insurance, and any association dues.

Borrowed funds: Cash that comes from a loan rather than your savings. Purchase programs treat it differently from your own money.

Reserves: Liquid cash left after closing to cover payments if rent stops. Many programs commonly look for about 6 months of PITIA.

How Underwriting Treats a Borrowed Down Payment, Step by Step

Two separate reviews happen here. One lender reviews the line. A different lender reviews the purchase. Each looks at the other’s loan, and the order you do things in matters.

Step 1: Choose the collateral. The line can sit on your primary residence, a second home, or a rental you own. The collateral changes the leverage ceiling, the credit minimum, and the maximum line size. The table below shows the differences.

Step 2: Qualify the line. The network’s lines run a debt-to-income test, with a 50% maximum. The cap drops to 45% for credit profiles from 600 to 679, and a ratio above 45% requires a 680 minimum. The payment is calculated on the interest-only amount on the maximum draw, not on what you plan to use. That is a stricter test than many borrowers expect. Credit comes from a single-bureau score model keyed to the primary wage earner, and the report can be no more than 90 days old at closing.

Step 3: Draw and move the cash. The consumer regulator describes a HELOC as an open-end line you can borrow against repeatedly during a draw period. Repayment follows. On this network, at least 75% of the line is drawn at closing. Move the cash into the account you will use for the purchase, and keep the transfer clean.

Step 4: Document the draw. Purchase lenders trace deposits. Expect to show the line’s closing documents, the statement showing the draw, and the transfer into your closing account. Some purchase programs want the cash to sit for a period before closing. Ask for the rule before you draw, not after.

Step 5: Purchase underwriting. On a DSCR loan, the property’s rent is compared to the property’s own payment. The line’s payment generally stays out of that ratio. On a loan judged by personal income, the line’s payment lands in your debt-to-income calculation. That is the big structural difference between the two paths.

Step 6: Sort the three buckets. Down payment, closing costs, and reserves are separate. A common pattern is that borrowed funds are accepted for the first two with documentation and excluded from the third. An undrawn line counts for nothing in any bucket. It reads as permission to borrow, not as an asset.

What the Wholesale Programs Allow

The parameters below come from the wholesale programs Lendmire places files with. They are guidance ranges, subject to lender guidelines and full file review, and not a commitment to lend. The ceiling depends entirely on occupancy.

Read the table carefully. The 90% figure exists only at a 720 or better profile, and only on primary residences and second homes. It reaches that level on lines up to $500,000. On a primary residence, a 700 profile reaches 85% on lines up to $500,000, and a 660 profile also reaches 85%. A 640 profile reaches 80%, and a 620 profile reaches 70% up to $400,000. On an investment property, the line caps at 70% CLTV, with no tier above it.

Lines run from $25,000 to $750,000. A line above $500,000 is primary-residence only. It needs a credit profile of 700 or better (720 on the longer-runway program, the one built around the 5-year interest-only draw). It caps at 75% CLTV and requires a full appraisal. Lines at or below $500,000 ordinarily use automated valuation with no traditional appraisal. A higher CLTV may call for a second valuation, and you can request a full appraisal in any case.

Structures. The line can sit in first or second lien position. On primary residences and second homes, two draw structures exist:

• A 3-year interest-only draw followed by a 17-year fully amortizing repayment.
• A 5-year interest-only draw followed by a 25-year fully amortizing repayment.

Investment lines run the 5-year draw and 25-year repayment structure only. Pricing floats through both the draw and the repayment period, and the line never converts to fixed. A subsequent draw after closing has a $1,000 minimum on the longer-runway program. Quote any figure together with its own structure.

Property types. Eligible types include single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not offered.

Exposure. A borrower can hold up to three lines. A borrower with more than 15 financed properties is not eligible.

Availability is narrower than the DSCR footprint. These lines are offered in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. DSCR investor loans run across 41 markets, including Washington, D.C.

Where the General Rule Breaks

The general rule says a documented, seasoned HELOC draw can fund the down payment. These cases break it.

A fully borrowed down payment. This is where plans fail first. Some purchase programs cap the borrowed share or want part of the down payment unborrowed. Stacking a 100% borrowed down payment on top of a 75%-to-80% purchase loan means close to full financing across two loans. If you run short, the home securing the line is at risk.

Reserves. The line may cover the down payment and closing costs but not the cushion. Plan on holding reserves from your own cash, commonly around 6 months of PITIA, with the amount varying by lender, leverage, and loan size.

An LLC-owned rental as collateral. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. A property already deeded to an LLC needs a vesting change first. Otherwise a DSCR cash-out refinance is the cleaner tool.

Listed properties. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA. If you plan to sell something and borrow against it, sequence matters.

Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by program on primary residences and second homes. One program accepts a foreclosure after 7 years, and a deed-in-lieu, pre-foreclosure, or short sale after 4. The other declines that history entirely, regardless of age. Investment files follow the 7-and-4-year path.

Renting out the home that secures the line. The CFPB’s HELOC booklet warns that renting the home to others may be prohibited under the line’s terms. The same booklet says that if you sell the home, you generally must pay the line off in full. It also says a line can be frozen or reduced if the home’s value drops. Read your agreement before moving out.

Variable payments. Because the line floats, the payment can rise during both the draw and the repayment period. Budget for that, not for the payment on day one.

When DSCR Takes Over After the Line

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. A line on your own home is a separate consumer product, reviewed on your personal income.

That split is why the pairing works. The new rental qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The line gets reviewed on you. The complete DSCR loans guide walks through how that ratio is built.

Here is what the purchase side typically looks like across the wholesale network:

• Purchase leverage: most files land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV at roughly a 700+ score, which means 15% down.
• 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.
• Loan sizes: up to $3,000,000 on standard programs (smaller balances available through select lenders). Above $2,500,000, the network generally holds to 30-year fixed structures.
• Reserves: commonly around 6 months of PITIA. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months.

One more point matters here. Clearing 1.00 is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the ratio. The line’s payment sits outside it too, but you still pay it.

A Worked Scenario in Ratios

Consider an investor who owns a primary residence with substantial equity and a 720+ credit profile. The target is a rental purchased at 75% LTV, which means 25% down. The investor wants the line to cover that down payment plus closing costs. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Three tests apply.

1. The line test. On a primary residence at 720+, the program can reach 90% CLTV on lines up to $500,000. Existing mortgage debt counts toward that figure. The line must also fit the 50% debt-to-income cap, tested on the full interest-only payment.

2. The rental test. Say the new property covers its PITIA at roughly 1.2x. That clears the baseline many select programs use. It says nothing about repairs or vacancy.

3. The cash-flow test. The investor carries the line’s payment from other income. If the rental sits vacant for a stretch, that payment keeps running.

Now size the line. Because at least 75% of it is drawn at closing, a line far larger than the need means interest on money you are not using. Size it close to the down payment plus closing costs, with a small cushion.

This scenario flips if the rental’s coverage sits below 1.00. Select lenders in the network do take sub-1.00 files, with leverage and terms adjusted. Pairing a thin ratio with a fully borrowed down payment stacks two risks. In that case, a larger cash down payment or a different property is often the better answer. When the numbers only work with maximum borrowing, that is a signal to re-examine the deal, not the loan type.

Who Fits and Who Should Skip It

It fits when you hold real equity in a home with a stable payment history and can carry the line’s payment from other income. It also fits when the rental covers its own payment with room to spare, and when you have a plan to pay down or refinance the line.

It fits less well when you plan to hold the property in an LLC from day one, the line would become your only reserve, or you already carry several financed properties. At that point, a DSCR cash-out refinance on a rental you already own can be the cleaner source of down-payment cash. Across most of the network, that cash-out ceiling is around 75% LTV on standard rentals, with about 6 months of seasoning commonly expected. The exit works in reverse too. A DSCR cash-out refinance can later pay off the line.

A third group should skip it. If the only way to buy is borrowing 100% of the down payment on a property that barely covers itself, a line is not the fix.
