Best HELOC Program to Cover a Down Payment Before Closing

The Quick Read: The right line is one that is open and funded before the purchase lender needs to source your cash, sits on a property you can pledge in your own name, and is accepted by that purchase lender as a down-payment source, with the leverage ceiling set by the pledged property’s occupancy. Two separate approvals have to hold. The line lender approves you and the collateral, and the DSCR purchase lender decides whether borrowed funds can count toward the down payment. Lendmire is a mortgage broker and arranges these lines through select wholesale partners. It is not the lender.

• On this network, a line against an investment property tops out at 70% CLTV, with a 700 minimum credit score and a $500,000 maximum line.
• Primary-residence and second-home lines reach 90% CLTV only at a 720-or-better credit profile.
• At least 75% of the line is drawn at closing, so the interest-only carry starts on most of it.
• LLCs cannot hold title on these lines, which is the sharpest structural difference from a DSCR loan.

What Does “Best Program” Mean for a Pre-Closing Down Payment?

The best program for your situation is the one whose collateral, leverage ceiling and draw structure fit a short bridge between “cash needed” and “purchase closed.” No single product wins on every file. Four criteria separate a workable line from a stalled one:

• Collateral you can pledge. The line goes on a property held by you or your revocable living trust, not on the property you are buying.
• A ceiling that clears your equity. The ceiling depends on occupancy and credit tier, and the pledged home’s existing mortgage uses part of it.
• A draw structure you can carry. Because most of the line is drawn at closing, the interest-only period needs to outlast your plan to refinance or pay it down.
• A purchase lender that accepts the funds. A line that closes cleanly is still useless if the DSCR lender will not take borrowed cash as a down payment.

Lendmire’s wholesale network runs several HELOC programs with different terms, so a broker can match the file to the program. The lenders that write a given file depend on the property type, the credit profile, the amount of equity and the documentation. They do not depend on a ranking.

Key Terms Defined

HELOC: A revolving credit line secured by equity in a property, drawn in cash as needed up to an approved limit.

CLTV (combined loan-to-value): All loans secured by a property, added together and divided by its value.

Draw period: The stretch when you can borrow and typically pay interest only, before repayment of principal begins.

Seasoning: How long funds sit in your account, or how long you have owned a property, before a lender treats them as established.

DSCR: The property’s monthly rent divided by its monthly obligation (principal, interest, taxes, insurance and any HOA dues). A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

How Underwriting Treats a HELOC Down Payment, Step by Step

Two lenders look at two different things. The line lender underwrites you, using personal income, debt and credit. The DSCR lender underwrites the rental property, using rent against the payment. The steps below keep those two reviews from colliding.

1. Find your available equity. Take the pledged property’s value, apply the CLTV ceiling for its occupancy and credit tier, then subtract the existing first mortgage. Most lines of $500,000 or less run on an automated valuation. A full appraisal is required above $500,000, and you can request one on any line.

2. Ask the purchase lender first. Before the line is opened, confirm whether the DSCR program accepts borrowed funds for the down payment, whether it caps the borrowed share, and whether it treats down payment, closing costs and reserves as separate tests. Get the answer in writing.

3. Qualify for the line. The line lender caps DTI at 50%, drops that cap to 45% for scores from 600 to 679, and requires a 680 minimum for any ratio above 45%. DTI is measured on the interest-only payment calculated on the maximum draw, not on what you plan to use.

4. Close the line and draw. At least 75% of the line is drawn at closing. Move the cash into your own account and keep the agreement, the draw record and the statements showing funds moving to escrow.

5. Underwrite the purchase. The DSCR lender verifies and sources the down payment, then tests the property’s rent against the new loan’s payment. On most files, the line payment sits outside that ratio. It still hits your real cash flow.

6. Treat reserves as a separate test. Reserves vary by lender, leverage, loan size and transaction type, and commonly run around 6 months of PITIA on a DSCR file. Borrowed money that is acceptable for the down payment is often excluded from reserves. Confirm this per program.

Program Structures and Ceilings

The ceilings are tiered by occupancy, and the investment tier is the lowest. A high-ceiling figure quoted for a primary residence does not describe a rental.

Credit tiers step the ceiling down. A primary residence at 700+ reaches 85% CLTV on lines up to $500,000, and 75% up to $750,000. A second home at 660+ reaches 80%. Lines above $500,000 are primary-residence only, cap at 75% CLTV and need a full appraisal. The credit requirement for a line above $500,000 is 700 or better (720 on the longer-runway program). The network has two wholesale programs: a higher-leverage program, and a longer-runway program with a longer interest-only runway. Their terms differ in places, so each figure applies only within its own program.

Each program offers two draw structures:

• 3-year interest-only draw with a 17-year fully amortizing repayment (primary residences and second homes).
• 5-year interest-only draw with a 25-year fully amortizing repayment.
• Investment lines run the 5-year draw and 25-year repayment structure only.

Tennessee shortens both structures. Pricing floats across the draw and the repayment period and never converts to fixed. For context on how revolving lines behave, the CFPB’s HELOC explainer notes that a draw period can run about ten years, that repayment often follows over ten or twenty years, and that the pricing is usually variable, so payments can change month to month. The network’s draw structures are shorter than that general example, so plan the exit around the specific structure on your file.

Lines can sit in first or second lien position. After closing, the minimum subsequent draw is $1,000, except Texas at $4,000, a figure the longer-runway program states.

Where the General Rule Breaks

Most of the failures on these files come from one of the edge cases below.

The line goes on the wrong property. A second lien placed on the property you are buying at closing is commonly refused. The line belongs on a different property that you already own.

The rental is titled in an LLC. Title must be fee simple or leasehold held by an individual borrower or a revocable living trust. LLCs, corporations, partnerships and irrevocable, blind or land trusts cannot hold title. A rental already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.

A first-time investor has no rental to pledge. An investment-property line needs an existing rental with equity. A first-time buyer can use only the equity in a primary residence or second home.

A recently bought rental has little room. A rental bought at 75%-80% LTV leaves little room under a 70% CLTV investment ceiling. NerdWallet’s investment-property HELOC guide reports that fewer lenders offer these lines, that borrowing limits run below primary-home limits, and that multiple appraisals may be required. It also cites typical market requirements of about a 720 score and at least 20% equity. On this network, investment lines start at a 700 score and cap at 70% CLTV.

The line is too small for the plan. On a purchase, most DSCR files land at 75%-80% LTV, which means 20%-25% down. Select programs reach 85% LTV (15% down) with roughly a 700+ score. If the line covers the entire down payment, the combined position approaches 100% financing, so the DSCR lender will test whether the borrowed share is allowed. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

Texas primary residences follow separate rules. A Texas primary residence is a homestead. It caps at 80% combined loan-to-value, carries a waiting period and a one-lien-at-a-time rule, and requires 12-month seasoning. Texas second homes and investment properties are eligible as non-homestead transactions. Properties are limited to 10 acres.

Listed or ineligible properties. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX and WA. New Mexico and Ohio apply a CLTV cap that depends on the credit profile. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties, and agricultural zoning are not eligible. Single-family, 2-4 unit, PUD, townhome and condominium properties (including non-warrantable condos) are.

Exposure limits. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower owning more than 15 financed properties is not eligible.

Availability. These lines are arranged in Lendmire’s 16 full-service states only (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA). That is narrower than the DSCR footprint, which spans 41 markets, including Washington, D.C.

How Agency Rules Compare

DSCR loans are not agency products, but a contrast helps. Fannie Mae’s selling FAQ says borrowed funds secured by an asset are an acceptable source for down payment, closing costs and reserves, because they represent a return of equity. DSCR and other non-QM programs set their own rules instead. Across the network, some programs accept a fully borrowed down payment, some cap the borrowed share, and some want a minimum from the investor’s own cash. That is why step two above comes before the line is opened.

What the Investor Decision Looks Like

A HELOC works best when three things are true:

• The cash need is temporary.
• The pledged property has equity under its ceiling.
• The purchase lender has already accepted the structure.

The cost is a second obligation on top of the new loan. The two debts share one rent stream. Passing 1.00 on a DSCR file is not the same as positive cash flow, because repairs, vacancy, management, utilities and capex sit outside the ratio. A line that was drawn at 75% or more at closing starts accruing interest on that full balance, so the carry belongs in your own cash-flow math even when the DSCR lender does not count it.

Picture an investor with a primary residence and a credit profile at 720 or better who wants to put 20%-25% down on a rental. Equity on the home may cover it. The line adds to the home’s CLTV, and the home is the collateral. A cash-out refinance on a standard rental tops out around 75% LTV, with about 6 months of seasoning as the common expectation. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Compare a second investor who owns a rental titled in an LLC. This investor cannot pledge it for a line, so the choices are a vesting change, a DSCR cash-out refinance on that rental, or a line against a different property held personally. Each path has different seasoning and title steps, so the order of operations matters more than the product label.
