Best HELOC Program for the Down Payment on a Construction Loan

The Quick Read: The best program is the one that fits your collateral property, your credit profile, and the cash gap you need to close, and it still has to pass the construction lender’s own rules on borrowed funds. A home equity line only supplies the cash portion of the project. The construction loan pays for the build, and a DSCR loan can replace it once the property is finished and rented.

• Two files, not one. The line lender looks at the property securing the line. The construction lender looks at the build, your finances, and whether borrowed cash is allowed.
• Occupancy sets the ceiling. On an investment property, the network’s line tops out at 70% CLTV. On a primary residence or second home, 90% exists only at a 720 or better credit profile.
• Size the line to the gap. At least 75% of the line is drawn at closing, so you start paying on most of it right away.
• Plan the exit first. The finished property has to carry the permanent loan and the line together.

What Is a HELOC Down Payment on a Construction Loan?

It is cash from a line of credit on one property that you put into a new build on another property, or on land you already own. Construction lenders want you to have real money in the project. They size the loan against what the build will cost and what it will be worth, so your cash is the cushion beneath their loan.

Most borrowers use the cash for land, the first draw, or both. The line becomes a separate debt secured by the property you pledged.

Lendmire is a mortgage broker. It places these lines through select wholesale lenders and never lends the money itself. Every figure below is subject to lender guidelines and full file review. None of it is a commitment to lend.

Key Terms Defined

• HELOC: a revolving credit line secured by a property you own, drawn against its equity.
• CLTV (combined loan-to-value): all liens on the property added together, divided by its value.
• Draw period: the stretch when you can borrow from the line, usually paying interest only.
• Loan-to-cost (LTC): the construction loan as a share of the total project budget, which includes land, labor, materials, and permits.
• Takeout: the permanent loan that pays off the construction loan once the building is done.
• Prepayment penalty: a fee some investor loans charge if you pay them off early.
• Seasoning: the waiting period a lender wants between buying or building a property and refinancing it.

Who Decides: The Line Lender or the Construction Lender?

Both do, and neither knows what the other will say. No rule bars a borrower from using line proceeds as a down payment. The construction lender’s own program decides whether borrowed funds count.

Some accept borrowed cash if you document the source. Others refuse it once they learn the money came from a line.

So the sequence matters. Ask the construction lender in writing about borrowed funds before you open the line. A broker who places both sides can often sort this out early, because the guidelines differ from lender to lender.

How Underwriting Treats the Line, Step by Step

1. The line is underwritten on its collateral. The lender values the property you pledge, adds every lien on it, and applies a CLTV cap that depends on the occupancy and your credit.

2. Your debts get recalculated. The network’s lines allow up to a 50% debt-to-income ratio, or 45% for credit profiles from 600 to 679. A ratio above 45% requires at least a 680 score. The payment used is interest-only, calculated on the maximum draw, not on what you plan to borrow.

3. The construction lender sees a new debt. The line payment goes into your profile. A heavily drawn line can crowd out the very construction loan it was meant to help.

4. The cash moves and gets documented. Keep the line agreement, the draw statement, and the transfer into your account. Source clarity helps; hiding it does not.

5. The construction lender releases funds in stages. Money goes out in draws against milestones, and you pay interest only on what has been paid out.

6. The build finishes and the takeout begins. The permanent loan replaces the construction loan, and the line stays behind unless you pay it off.

The CFPB explains that a home equity line is an open-end credit line with a draw period followed by a repayment period. It also warns that missing payments can put the home at risk. The collateral is your property, not the build.

What Makes One Program Better Than Another?

Fit matters more than any single feature. Across the wholesale network Lendmire places files with, the criteria that move a decision are collateral type, credit profile, line size, and how much of the line you must draw at closing. This table shows how the ceilings split by occupancy.

Read the ceiling cell with its credit pairing. A 90% ceiling never applies to an investment property. On a primary residence, the 90% tier covers lines only up to $500,000. Lines above $500,000 are primary-residence only, cap at 75% CLTV, and require a full appraisal.

Other criteria worth comparing:

• Draw structure. Primary residences and second homes can take a 3-year interest-only draw followed by a 17-year repayment period. They can also take a 5-year draw followed by a 25-year repayment. Investment lines run the 5-year/25-year structure only.
• Pricing behavior. Pricing floats through both the draw and repayment periods and never converts to fixed.
• Valuation. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. A higher CLTV may call for a secondary valuation, and you can request a full appraisal in any case.
• Lien position. The line can sit in first or second position.

Any one lender in the network will write only some of these combinations. The best program for your situation depends on which combination your collateral and credit support.

Which Property Should Secure the Line?

A line on your primary home usually gives you the most room, and a line on a rental gives you the least. On the network, the investment ceiling is 70% CLTV with a 700 minimum score. A primary residence can reach 85% at a 700 score, or 90% at a 720 score on lines up to $500,000.

Do not pledge a property without reading the line terms first. The CFPB’s HELOC booklet notes that renting out your home may be prohibited under the terms of a line. That matters if the home you pledge later becomes a rental.

Title is a hard rule here. The borrower must hold the property individually or in a revocable living trust. LLCs, corporations, and partnerships cannot hold title. A property already in an LLC needs a vesting change first, or a DSCR cash-out refinance instead.

Availability is narrower than the DSCR side. The equity line is offered only in Lendmire’s 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA. Texas primary residences are homesteads and cap at 80% combined loan-to-value.

Where the General Rule Breaks

You already own the land. Equity in the lot may count toward the construction lender’s cash requirement. You might not need a line at all, or only enough to cover the gap. Only equity counts, meaning value minus liens, not the gross land value.

The down payment is fully borrowed. A line that funds your whole cash contribution leaves you almost no equity in the project. A budget overrun has nowhere to land.

The line is nearly fully drawn on day one. The network requires at least 75% of the line to be drawn at closing. Do not size the line “just in case.” Interest-only payments start on the drawn amount immediately, while the construction loan is still paying out in stages.

The building type is excluded. Manufactured homes, log homes, and barndominiums are not offered on the network’s DSCR programs. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are also ineligible as line collateral. Check the type before you design the exit.

You run into the borrower limits. A borrower is limited to three lines. Anyone owning more than 15 financed properties is not eligible.

Tax. 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 Exit: Where a DSCR Loan Fits

A DSCR loan is the common permanent loan on a finished rental. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR loans are designed for non-owner-occupied investment properties. They are reviewed differently from a standard owner-occupied mortgage. Most DSCR programs fund the finished property, not construction draws, so the file starts after completion. Read the complete DSCR loans guide for the full mechanics.

A few program realities from across the network:

• Many select programs start at 1.00 coverage. A separate select-lender path goes below 1.00, with leverage and terms adjusted.
• On a purchase, most files land at 75% to 80% LTV. A cash-out refinance tops out around 75% LTV across most of the network, with about six months of seasoning common.
• Most programs want around a 660 score. A 620 floor exists in parts of the network. 700 and up opens the strongest leverage tiers.
• The standard 30-year fixed is the spine. Extended terms and interest-only periods are available through select lenders.
• Some DSCR loans carry a prepayment penalty. That makes paying off the DSCR loan early, such as through a quick refinance, more expensive.
• A DSCR takeout may be written to an LLC, depending on program guidelines.

The DSCR ratio compares rent to the property’s PITIA: principal, interest, taxes, insurance, and any association dues. It does not include your line payment. A property can clear 1.00 and still strain you if the line payment sits on top. Clearing 1.00 is also not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses sit outside the ratio.

If you want to pay off the line with the takeout, you are looking at a cash-out refinance, with its own leverage cap and seasoning. If you plan to keep the line, test the stabilized rent against both debts together.

Who This Fits, and Who Should Look Elsewhere

This works best for an owner with solid equity in a primary or second home, a credit profile in the upper tiers, and a build that will rent for enough to carry both debts. The strongest files clear two tests: enough equity and enough rental coverage.

Look at other options if:

• Your construction lender will not accept borrowed cash. Then the line solves nothing.
• The collateral is a rental, and your credit is below 700.
• Your cash gap is small. A smaller line, or the equity in land you already own, may do the job.
• The property is held in an LLC, and you do not want to change the title.

A broker that shops multiple wholesale lenders can match the collateral, credit, and line size to the program that writes it. The right match depends on property type, credit profile, leverage need, and documentation.
