Best Bank Statement HELOC Program for the Down Payment on a Construction Loan

The Quick Read: A bank statement HELOC can fund the equity a construction lender requires, but the best program for your situation depends on three things: which property secures the line, how much combined leverage that property allows, and whether the construction lender accepts borrowed money as your stake. You are dealing with two separate underwritings, and approval on one never guarantees the other. Everything below is subject to lender guidelines and full file review, and none of it is a commitment to lend.

• The line is secured by a property you already own, never by the new build.
• Investment-property collateral tops out at 70% CLTV on this network. The 90% tier exists only on primary residences and second homes at a 720-or-better credit profile.
• Qualifying lenders measure your debt using the interest-only payment on the full line, not just what you draw.
• At least 75% of the line is drawn at closing on both draw structures, so size the line to the gap, not the maximum.
• A line is not a free down payment. It is borrowed equity that adds a second payment on top of the construction loan.

Will a Construction Lender Accept HELOC Money as My Down Payment?

Many will, but policy varies by construction lender, and you should ask before you open the line. Construction lenders treat HELOC draws as borrowed funds. They will trace where the money came from, and they will count the HELOC payment in your debt load.

That is why this strategy involves two files. The first is the HELOC lender’s file, which asks whether you and the collateral property qualify for the line. The second is the construction lender’s file, which asks whether your equity stake is real and whether you can carry every payment at once.

Before you pay for an appraisal or a credit pull, ask the construction lender these questions:

• Do you accept HELOC proceeds toward the required equity or cost share?
• Do you count the full line or only the drawn balance in my debt ratio?
• What paper trail do you want for the draw?
• Does land I already own count toward the stake?

A broker earns its keep here. Lendmire is a mortgage broker that works with a network of wholesale HELOC lenders, so it can match the line’s structure to what your construction lender will actually accept. The best program for you is the one both lenders can live with.

How Do the Two Loans Fit Together?

The sequence matters more than anything else. The line has to be open and funded before the construction loan closes, and the construction lender needs to see the money arrive.

1. Pick the collateral. This is a primary residence, second home, or rental you already own. The new build does not secure the line.

2. Check the equity. Your available equity is the property’s value minus the first mortgage, capped by the lender’s combined loan-to-value limit.

3. Qualify the line. The HELOC lender reviews credit, income documentation, debt ratio, and the property.

4. Close the line and take the draw. The money lands in your account as borrowed funds.

5. Show the construction lender the trail. Expect to hand over the HELOC statement and the deposit showing the draw.

6. Close the construction loan. Your equity stake now consists of land equity, HELOC cash, or both.

7. Build, then convert or exit. The construction lender releases money in stages. After completion, the loan converts to permanent financing or gets paid off.

The CFPB defines a HELOC as an open-end line you can borrow against repeatedly, using your home equity. When you already carry a first mortgage, the line sits behind it as a second lien. On this network a line can also sit in first position when the property has no mortgage.

How Does a Bank Statement HELOC Qualify You?

“Bank statement” describes how income is documented, not how generous the loan is. For a self-employed investor whose tax returns show heavy deductions, the lender reads deposit history instead. Where a program accepts this, you qualify on documented income under the applicable program, subject to lender guidelines. Large retail lenders mostly want traditional paperwork, so these lines are far more common through specialty and non-QM channels.

The rest of the file still looks like a normal equity-line file. On the programs Lendmire places files with, the main tests are:

• Credit: The floor is 600 on primary residences. Second homes start at 640 and investment properties at 700.
• Debt ratio: The maximum is 50%, dropping to 45% for credit profiles from 600 to 679. A ratio above 45% requires at least 680.
• Payment test: The lender reviews your file on the interest-only payment calculated on the maximum draw.
• Property: Single-family, 2-4 units, PUDs, townhomes, and condos (including non-warrantable condos) are eligible. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not.
• Title: The individual borrower or a revocable living trust must hold title. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot.

Coordinate the payment test with the construction lender’s math. The HELOC lender and the construction lender both look at your debt ratio, and a line sized larger than you need can squeeze you on the second file.

What Does Each Property Type Allow?

Your collateral’s occupancy sets the ceiling, and the differences are large. Leverage caps below apply by property use, subject to lender guidelines and full file review.

Two cautions. First, 90% exists only at a 720-or-better profile and only at lines up to $500,000. Second, a line above $500,000 is for primary residences only. It needs 700 or better (720 on the 5-year-draw program), caps at 75% CLTV, and requires a full appraisal. Lines at or below $500,000 ordinarily use an automated valuation, though a higher CLTV may call for a secondary one.

Market surveys and individual lenders sometimes advertise higher equity limits on investment-property lines. Those describe the broader market. On this network, a rental caps at 70% CLTV.

These lines are available only in 16 full-service states, which is narrower than the 41-market footprint for DSCR loans. A property listed for sale is also ineligible in several of those states.

Which Structure Fits a Construction Timeline?

Two draw structures exist on primary residences and second homes. The first is a 3-year interest-only draw followed by a 17-year fully amortizing repayment period. Investment properties run the 5-year structure only.

Both are interest-only during the draw period, and both float on pricing and never convert to fixed. For a build, the 5-year draw usually fits better. Construction often runs a year or more, and a repayment period that begins mid-project adds a larger payment at the worst moment.

At least 75% of the line is drawn at closing on both structures. That helps when your stake is due up front. It hurts when you only need part of the gap, because you carry interest on money sitting idle. Size the line to the gap you need to fill. Later draws carry a $1,000 minimum on the 5-year-draw program, which is the one that states a minimum.

What Does the Math Look Like?

Here is one illustrative scenario, in percentages only. Say a construction lender wants an equity stake of around 20% of total project cost. You own land free and clear that covers about half of that stake. The HELOC covers the other half.

Your collateral is a rental you own, valued at a round figure with a first mortgage equal to 45% of value. At the 70% CLTV investment ceiling, the line could reach about 25% of the property’s value, subject to credit, debt ratio, and the line cap. Whether that clears your gap depends on your project cost relative to the rental’s value.

Now run the second test. The construction lender adds the HELOC’s interest-only payment on the full line to your obligations. It adds the construction payment and the existing mortgage payment. If the combined ratio breaks the construction lender’s limit, a smaller line or more land equity fixes it. A larger line does not.

Sequence matters. Get the construction lender’s equity and debt-ratio requirements in writing first, then size the line to fit them.

How Do the Funding Options Compare?

A DSCR cash-out refinance on a standard rental tops out near 75% LTV, with about 6 months of seasoning as the common expectation. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It is a closed-end loan on the existing rental, not a line. Lendmire’s piece Best Bank Statement HELOC Program to Fund a Rental Down Payment as a Self-Employed Owner covers the same income-documentation mechanics for a purchase instead of a build.

Where Does the General Rule Break?

The general rule says a HELOC on property you own can fund your stake. These edge cases bend it:

• Title held in an LLC. An equity line cannot attach to a property deeded to an LLC. You would need a vesting change, or a DSCR cash-out refinance instead, subject to program terms.
• Rental collateral. Not every lender writes lines on rentals, and availability varies lender to lender. A broker can screen for the ones that do.
• Large portfolios. A borrower with more than 15 financed properties is not eligible, and borrowers are limited to three lines.
• Housing history. Derogatory events like a bankruptcy need 4 years of seasoning from discharge or dismissal. Foreclosure-family events split by program on primary residences, with one program seasoning them and the other declining them regardless of age.
• Low credit. Profiles below 640 are limited to single-family residences with a clean 12-month housing history under the 5-year-draw program.
• Value drops. The CFPB and the FTC both say a lender may freeze or reduce a line if the home’s value falls well below the appraised amount. That matters most when you draw in stages. Because you draw most of the line at closing here, the exposure is smaller, but later draws remain at risk.

What Happens When the Build Finishes?

Plan the exit before you borrow. After completion, the construction loan either converts or gets paid off. If you built the property to rent, the permanent loan is usually a long-term investor loan on the finished, leased property.

That is where DSCR underwriting comes in. 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. The lender compares rent to the full monthly housing obligation (principal, interest, taxes, insurance, and any HOA dues). On a purchase, most files land at 75%-80% LTV, with select high-leverage programs reaching 85% at roughly a 700+ score. Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted.

Your HELOC payment is not part of that ratio, and the ratio is not a measure of cash flow. Clearing 1.00 does not mean the property is cash-flow positive. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation. The HELOC payment will hit your real cash flow even though it never touches the property’s coverage number.

Remember also that the line’s interest-only draw period ends, and the repayment period can bring larger payments. If you plan to refinance out of the line, the rental collateral may carry its own prepayment terms, which can make an early refinance more costly. Review those documents carefully before you sign.

The line also stacks leverage. You hold the HELOC, the construction loan, and any first mortgage on the collateral. The new property then has to carry its own loan and cover the cost of the line. Interest accrues on every dollar you draw, including dollars sitting in your account waiting for the construction closing.

How Do You Choose the Best Program for Your Situation?

No program wins for every borrower. The lenders that write these lines differ on credit tiers, draw structure, property types, and how they treat existing liens. Use these criteria:

• Collateral occupancy: It sets your ceiling before anything else.
• Credit tier: The jump from 700 to 720 can mean the jump from 85% to 90% CLTV on a primary residence, and the 90% tier applies only at a 720-or-better credit profile.
• Combined leverage: Count the first mortgage, the line, and the construction loan together.
• Draw structure: The 5-year draw usually suits a long build better.
• Title: Confirm individual or revocable-trust vesting before you start.
• Construction lender overlays: Acceptance of borrowed funds is the gating question.

For the wider picture of how these pieces connect to long-term investor financing, see the complete DSCR loans guide. A broker that shops multiple wholesale lenders can match your scenario to the right one.
