HELOC Lenders to Cover a Down Payment Before Closing

The Quick Read: A home equity line can fund the down payment on a rental, but two separate approvals are involved: one for the line, and one for the DSCR purchase loan that has to accept borrowed funds. Which HELOC lender fits depends on the property securing the line, your credit profile, and how much combined leverage you can carry.

• The line and the rental loan are underwritten separately, so approval of one says nothing about the other.
• The line’s ceiling depends on the property that secures it: an investment property is held to a lower ceiling than a primary residence.
• On most DSCR files the line’s payment sits outside the coverage ratio, but you still have to pay it from real cash flow.
• Ask the purchase lender in writing whether borrowed funds are accepted, and for which part of the cash to close.

Lendmire is a mortgage broker. It does not lend. It places both kinds of loans through select wholesale lenders, which is why this article compares how those lenders treat the file instead of ranking companies.

Key Terms Defined

HELOC (home equity line of credit) is a revolving credit line secured by a property you already own. You draw against the equity in that property.

CLTV (combined loan-to-value) is every loan against a property, added together, divided by its value.

DSCR (debt service coverage ratio) is a property’s monthly rent divided by its monthly payment of principal, interest, taxes, insurance, and any HOA dues. That payment is called PITIA.

Draw period is the stretch when you can borrow from the line, usually paying interest only.

DTI (debt-to-income ratio) is your monthly personal debt payments divided by your monthly income.

Vesting is how title to a property is held: in your own name, in a trust, or in an entity.

Seasoning is how long money has sat in your account, or how long you have held an asset, before a lender counts it.

What Does a HELOC Actually Do in a Rental Purchase?

It turns equity in a property you already own into cash you can wire to the title company. The cash replaces money you would otherwise take from savings or a sale.

The rental lender does not care about the line itself. It cares about three things. First, where the cash came from. Second, whether the rental covers its own payment. Third, whether you hold enough cash and reserves on top.

Think of it as two tests. The first is equity: do you own enough in the home behind the line? The second is coverage: does the new rental earn enough to carry its own loan? The strongest files clear both. A big down payment can lift coverage by shrinking the new loan, but it never erases leverage caps, credit floors, reserve rules, or property eligibility.

Investors often use this approach because the sequence is straightforward. Taxstra, a tax-education publisher, describes opening the line, moving the draw into a dedicated account, and wiring funds from that account to the title company. Taxstra also recommends drawing only what the deal needs: down payment, closing costs, and any rehab buffer.

How Does Underwriting Treat It, Step by Step?

Each loan gets its own review, and the order matters. Here is how the pieces fit.

1. The line is underwritten on you and the property behind it. The lender looks at credit, existing liens, the value of the home, and your personal debt ratio. On the lines in Lendmire’s network, the maximum DTI is 50%, with one tighter limit for lower scores: profiles from 600 to 679 are held to 45%. Any ratio above 45% therefore requires a credit profile of at least 680. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you plan to borrow.

2. Value comes from an automated valuation or an appraisal. Lines at or below $500,000 ordinarily use automated valuation with no traditional appraisal, though a higher CLTV can trigger a second valuation. A full appraisal is required on every line above $500,000. You can also request one in any case.

3. You ask the DSCR purchase lender about borrowed funds. This step decides the outcome. Ask whether documented borrowed funds count toward the down payment, whether the borrowed share is capped, and whether some of the cash must be your own. Get the answer in writing.

4. You build the paper trail. Expect to show the line agreement, the draw record, and bank statements that trace the money into your account and out to closing. Disclose the source honestly. Leaving a line off an application is misrepresentation, and it puts the whole purchase at risk.

5. Borrowed funds are treated differently for down payment and reserves. Many lenders accept borrowed funds for the down payment and closing costs, and exclude them from reserves. Treatment varies by lender, and some ask for seasoning on the funds without a single standard period.

6. The rental is judged on its own rent. The DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. The line’s payment generally sits outside that ratio. A DTI-based loan, such as a bank-statement or full-documentation loan, would count it.

What Do the Lines Look Like by Property Type?

The answer changes with the property securing the line. The ceiling is not one number, so match it to the property you plan to borrow against. Programs change, and every file is reviewed individually, subject to lender guidelines.

On a primary residence, the 90% ceiling exists only with a 720 or better credit profile and a line up to $500,000. Lower scores step down: 85% CLTV at 660 to 700, 80% at 640, 70% at 620, and 60% at 600. A line above $500,000 is for primary residences only, caps at 75% CLTV, and needs a credit profile of 700 or better (720 on the longer draw structure).

On a second home, the 90% ceiling again requires 720 or better, and a 640 profile tops out at 75% CLTV. On an investment property, the ceiling is 70% CLTV, with no exceptions.

A Texas primary residence is a homestead, so it caps at 80% combined loan-to-value. Second homes and investment properties in Texas follow the standard tables.

What Structures Exist?

A standalone line can sit in first or second lien position. That means it can be your only loan on the property or a second loan behind an existing mortgage.

There are two draw structures on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year repayment. The other has a 5-year draw followed by a 25-year repayment. Investment lines run only the 5-year draw and 25-year repayment structure.

Two features surprise first-time users. First, at least 75% of the line must be drawn at closing. This is a standalone product, not an idle safety net, so size it for the cash you need. Second, the cost of the line floats through both the draw and repayment periods and never converts to fixed.

Title matters too. The property securing the line must be held by you individually or by a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. That is the sharpest structural difference from a DSCR loan. If your existing property already sits in an LLC, you would need a vesting change or a DSCR cash-out refinance instead. Our DSCR cash-out refinance article covers that route.

Where Does the General Rule Break?

The usual advice is open the line, draw the cash, and buy. These edge cases bend it.

The line can shrink before you close. The CFPB’s HELOC explainer notes that a lender may restrict credit if the home’s value drops significantly. The CFPB HELOC booklet adds that a lender can freeze or reduce a line if values fall or your finances worsen. If the line is your down payment, a reduction mid-transaction can derail the purchase. Draw the cash into your own account early and keep it there.

The payment grows later. On the network’s lines, the interest-only phase is a few years, not a decade. A long hold needs a plan for that shift.

A fully borrowed down payment stacks leverage. On a purchase, most DSCR files land at 75% to 80% LTV, with select high-leverage programs reaching 85% at roughly a 700+ score. Borrow the entire down payment against another property, and your combined debt approaches 100% of the purchase price. Some purchase programs will not accept that. Others require part of the cash to be your own. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

Your home is the collateral. Falling behind on the line puts the property that secures it at risk. Using a primary residence to back a business purchase is a real risk, and it deserves a clear exit plan.

Some properties are out. Manufactured homes, co-ops, condotels, log homes, and commercial, mixed-use, or agricultural-zoned properties are not eligible for these lines. On the DSCR side, manufactured homes (single- and double-wide), log homes, and barndominiums are not offered.

Listings can disqualify a property. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas, and Washington. That matters if you plan to sell the home you are borrowing against.

Availability is narrow. These lines are available in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA.

A line is not a sell-before-you-buy plan. If your plan depends on selling the home to repay the line, a delayed sale leaves you carrying the line and the new loan together. Know your fallback before you draw.

Why Does the Rental’s Coverage Still Matter?

Clearing 1.00 on DSCR does not mean the property makes money. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation, and so does the payment on your line.

A DSCR of 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. The path you land on affects how much cash you need at closing, which circles back to how large a line you size.

Here is a modeled picture. Say you are buying a duplex with a down payment of 25%, which is typical for a purchase at 75% LTV. The rent comfortably clears 1.2x on the new payment. On paper, that looks strong. But you also carry a first mortgage on your home, a line drawn to fund the down payment, and the rental loan. If the line’s payment strains your budget, a healthy DSCR will not rescue the monthly picture. Size the line against real cash flow, not only against the ratio. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

The same exercise works in reverse. A larger down payment can lift coverage, but if the line’s payment eats the improvement, you have moved debt, not solved it.

How Do You Find the Right HELOC Lender?

The right program depends on your situation: which property secures the line, your credit profile, the leverage you need, and how the purchase lender treats borrowed funds. No single lender fits every file. A broker that works with multiple wholesale lenders matches the scenario to the program, which is the main advantage over walking into one lender’s door.

Bring these to the conversation:

• Occupancy of the securing property. Primary, second home, or investment, since the ceilings differ sharply.
• Credit profile. The minimum is 600 on primary residences, 640 on second homes, and 700 on investment properties.
• Current liens and estimated value. These set how much CLTV room you have.
• Vesting. Individual or revocable trust works. An entity does not.
• The purchase lender’s rule on borrowed funds. Get it in writing before you open the line.
• Planned exit. Refinance, paydown from a sale, or a cash-out on the new rental after it is stabilized.

Consider this contrast. An investor with strong credit and a primary residence sits in the higher-ceiling tiers. An investor borrowing against an existing rental faces the 70% ceiling and a 700 floor. The same down payment target can be easy for one and tight for the other.

For the big picture, see the complete DSCR loans guide.

Is It Worth Doing?

It tends to work when the equity is real, the line is sized tightly, and the rental carries itself without leaning on the line’s payment. It tends to fail when the borrowed down payment pushes combined leverage near the ceiling, or when the plan depends on a sale that has not happened.

A HELOC alone does not scale across many deals. Each line draws on one property’s equity, and a borrower is limited to three lines. A plan to refinance or pay down the line after the rental stabilizes is the usual answer.
