Top HELOC Providers to Fund a Home Construction Project

The Quick Read: The right HELOC provider for a build depends on your situation, not a ranked list, because each lender’s occupancy rules, credit floors, and combined-leverage caps decide whether a line fits your project, how much it can reach, and what the draw and repayment schedule looks like. A HELOC borrows against equity in a home you already own. It does not finance the new structure directly.

• Leverage is capped by occupancy. Combined loan-to-value (CLTV) adds your first mortgage and the new line, then divides by the home’s value. On an investment property, the network ceiling is 70% CLTV. On primary-residence and second-home lines, it reaches 90% CLTV, but only at a 720 or better credit profile and only on lines up to $500,000.
• Most of the line is drawn at closing. At least 75% of the line is funded on day one, so you carry interest-only cost on most of the balance before the first contractor invoice arrives.
• The line floats. Pricing moves across the draw and repayment periods and never converts to fixed.
• Nobody inspects the build. Unlike a construction loan, a HELOC has no inspection-gated draws, so contractor oversight is your job.
• Title matters. These lines go to individuals or revocable living trusts. An LLC cannot hold title.

What Does a HELOC Actually Do in a Construction Budget?

A HELOC turns existing home equity into a pool of cash you can pull from during a set draw period. It works best when you already own a home with plenty of equity and the full build cost fits inside the line. It works poorly when you need the lender to fund the project against a future, finished value.

The line is sized on what the pledged home is worth today. That home might be your residence, a second home, or a rental you already own. The project you are building does not count toward the line until it exists and has its own value.

Investors use HELOCs for construction because they avoid some of the paperwork of a construction loan. A fix-and-flip lender or a construction lender wants plans, budgets, and inspections. A HELOC lender looks at your credit, your debt load, and the equity in the home you pledge. Most of the tradeoffs below come from that difference.

Key Terms Defined

HELOC is a home equity line of credit, a revolving credit line secured by your home. You borrow against it up to a limit.

Draw period is the stretch when you can borrow from the line and payments are interest-only. On this network it runs 3 or 5 years, depending on the structure.

Repayment period is the stretch after the draw ends, when the balance amortizes. Payments rise because principal is now included.

CLTV is combined loan-to-value: the first mortgage plus the line, divided by the home’s value.

Vesting is how title to the property is held, such as in your own name or in a revocable living trust.

DSCR is the debt service coverage ratio, a rental property’s rent compared with its full monthly obligation. It matters later, when you refinance the finished build.

Who Writes These Lines? Provider Types Compared

Four kinds of providers write HELOCs, and the right one depends on your property and your plan. A ranked list of company names would go stale and ignore your file. The type of provider tells you more.

NerdWallet notes that a HELOC on an investment property is not offered by all lenders and that qualification is strict. It also reports that market-wide maximums reach about 80% LTV, with many lenders below 70%. On Lendmire’s network, an investment-property line tops out at 70% CLTV.

A broker shops multiple wholesale lenders against one scenario. Lendmire does not lend on these files. It arranges them through select wholesale partners, and the lender reviews eligibility and approves. Availability for these home equity lines covers 16 full-service states (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, and WA). That is narrower than the 41-market DSCR footprint.

How Underwriting Treats a Construction-Funding Line, Step by Step

Underwriting a HELOC looks at you and your existing home. It does not look at the project. Here is the sequence a file moves through.

1. Collateral. The lender identifies the home you are pledging. It must be eligible: single-family, 2-4 units, PUD, townhome, or condominium, including non-warrantable condos. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not eligible.

2. Title. The borrower must hold title individually or through an inter vivos revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title.

3. Credit. The program floor is 600, and it is a single-bureau score keyed to the primary wage earner. The report can be no more than 90 days old at closing, and there are no rescores. Second homes start at 640, and investment properties at 700.

4. Debt-to-income. The maximum DTI is 50%, but profiles scoring 600 to 679 are held to 45%. Any ratio above 45% requires at least a 680 score. The lender reviews your file on the interest-only payment calculated on the maximum draw, not on what you have drawn.

5. Valuation. Lines at or below $500,000 ordinarily use an automated valuation with no traditional appraisal, though a higher CLTV can trigger a secondary valuation. A full appraisal is required above $500,000, and you can request one in any case.

6. CLTV sizing. The lender takes the maximum CLTV for your credit tier and occupancy, subtracts what you owe on the first mortgage, and the remainder is your line, up to the program’s dollar cap.

7. Closing and draws. At least 75% of the line is drawn at closing. After that, the minimum subsequent draw is $1,000 on the longer-runway program, the one with the 5-year interest-only draw and 25-year repayment.

Step four catches many construction borrowers off guard. A large line on a high-value home can look affordable until the lender underwrites the payment as if the whole line were drawn.

What Do the Limits Look Like by Occupancy?

The ceiling depends on how the pledged home is used, so no single leverage number covers every borrower. Across the network, primary residences get the most room, second homes sit in the middle, and investment properties get the least.

The 90% ceiling on a primary residence or second home applies only to lines up to $500,000. On a primary residence, a 720+ or 700+ profile reaches 75% CLTV on lines up to $750,000. Lower tiers step down; a 640+ primary-residence profile, for example, tops out at 80% CLTV up to $500,000. A line above $500,000 is for primary residences only, requires a credit profile of 700 or better (720 on the longer-runway structure), caps at 75% CLTV, and needs a full appraisal.

Two structures exist on the network. One has a 3-year interest-only draw followed by a 17-year fully amortizing repayment. The other, the longer-runway structure, has a 5-year draw followed by 25 years of repayment. Investment-property lines use the 5-year, 25-year structure only. Pricing floats on both and never converts to fixed. Tennessee shortens both structures.

Where the General Rule Breaks

Most of these lines work the way the table says. A few situations change the answer.

The build costs more than the line. The line has a hard dollar cap and a CLTV cap. If the project does not fit inside both, a HELOC alone does not finish it. Borrowers then pair it with other capital or choose a construction loan.

The collateral is the build site. A HELOC is sized on the current value of a finished home. A vacant lot or a half-built house is generally not what a line is built to borrow against. Using equity from a different home is the common route.

The pledged home is rented. The Consumer Financial Protection Bureau’s HELOC booklet warns that renting out your home may be prohibited under the terms of your line. Read the agreement before you borrow against a home you plan to rent.

The line gets frozen or cut. The same booklet notes that a lender can reduce a line if the home’s value falls. A build that stretches over many months is exposed to that risk.

You sell or refinance the pledged home. The booklet says that if you sell the home, you generally must pay off the HELOC in full. A refinance of the first mortgage can also force a decision about the line.

The pledged home is in an LLC. These lines cannot go to an LLC-titled property. A home already deeded to an LLC needs a vesting change first, or a DSCR cash-out refinance instead.

Portfolio limits apply. A borrower is limited to three lines, with combined exposure capped at $2,000,000 on the higher-leverage structure and $750,000 on the longer-runway structure. A borrower with more than 15 financed properties is not eligible.

The deduction question. Investors often ask whether interest on a construction line is deductible. 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.

HELOC, Construction Loan, or DSCR Refinance?

A HELOC trades control for flexibility. A construction loan pays out in milestone draws, usually after an inspection, which protects you from a contractor who takes a deposit and disappears. It also ties the debt to the project, not to your home. A HELOC has no such check. The money is in your account, and nothing stops you from paying a contractor ahead of the work.

The risk also differs. A line secured by your primary residence puts that home at risk if the project goes wrong. The Consumer Financial Protection Bureau states plainly that you could lose your home if you fall behind or cannot repay on schedule. That includes the draw-period structure, where payments are interest-only and then step up.

Where the build is a rental, the exit usually runs through a DSCR loan. 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 loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

A few network figures matter for that exit. On a cash-out refinance of a standard rental, leverage tops out around 75% LTV, and about 6 months of seasoning is the common expectation. 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. Credit floors run from 620 in parts of the network, to around 660 for most programs, to 700+ for the strongest leverage tiers. Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders).

DSCR compares rent to the full monthly obligation (principal, interest, taxes, insurance, and any association dues). Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, and utilities sit outside the calculation. LLC ownership is possible on DSCR files, subject to lender program eligibility. For the full picture, see Lendmire’s complete DSCR loans guide.

A Staged-Draw Walkthrough

Picture an owner with a primary residence worth $450,000 and a first mortgage at roughly 55% of value. The owner has a 720+ credit profile and wants to add a detached unit. At the 90% CLTV ceiling for that credit tier and a line under $500,000, the available line equals the gap between 55% and 90% of the home’s value. That is a large amount of room, and a valuation would still confirm the home’s value.

Here is how the line behaves through the build:

• Closing. At least 75% of the line is funded immediately. The owner now carries interest-only cost on most of the line, whether or not any concrete has been poured.
• Excavation and foundation. The owner pays the contractor from funds already drawn. The lender sees none of this.
• Framing and mechanicals. The remaining draws ($1,000 minimum each) cover later invoices. No third party checks the work.
• Slip. If the schedule slips, interest-only cost keeps running on the large balance. Pricing floats, so it can change in the middle of the build.
• After the draw period. The line moves to fully amortizing repayment. The payment steps up, and a project that has not been refinanced or paid down feels it.

The lesson is that a HELOC front-loads cost and leaves oversight to you. It works best when the project budget is firm, the contractor is trusted, and the exit is planned.

What to Prepare Before You Apply

Lenders on the network ask for the same basics every time. Gather these first:

• Collateral facts. Occupancy, property type, current value estimate, first-mortgage balance, and how the home is titled.
• Credit profile. A score for the primary wage earner, plus tradeline and housing-history standards that vary by program. The longer-runway structure wants two tradelines seasoned 12 months, or one seasoned 24.
• Debt picture. Your DTI, run on the maximum draw, not the balance you plan to use.
• Project budget. The all-in cost, with a cushion, compared against the line’s dollar cap and CLTV cap.
• Exit plan. Whether you will pay down the line, sell, or refinance into long-term financing once the build is finished.

Bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits: one structure seasons a foreclosure in 7 years and a deed-in-lieu, pre-foreclosure, or short sale in 4, while the other declines the history entirely, regardless of age. Property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.
