Top Investment Property HELOC Providers on a Rental Built Under a Construction Loan

The Quick Read: A line of credit cannot fund the build itself, because it needs a finished property, a recorded lien and a value to lend against. After completion, the construction loan is repaid or converted, and then a line can be placed on the rental. Which provider fits depends on the file, not on a ranking.

• A HELOC is a revolving line secured by a finished property. A construction loan is short-term draw financing. They are two separate products.
• On the network’s investment lines, the ceiling is 70% CLTV, with a 700 minimum credit score and a maximum line of $500,000.
• Investment lines run a 5-year interest-only draw followed by a 25-year repayment period, and the pricing floats throughout.
• Title must sit with an individual or a revocable living trust. An LLC cannot hold title on these lines.
• Lines are available only in Lendmire’s 16 full-service states, which is narrower than the DSCR footprint.

Builders and investors often ask which lenders offer these lines. The honest answer is a fit question. Lendmire is a mortgage broker, not a lender. It shops a network of wholesale HELOC lenders and matches the property, the equity, the title and the credit profile to a program. This article does not rank or name lenders, because the right one depends on the file.

Why “Top Providers” Is a Fit Question

The provider that works for one rental can decline another. The fit turns on the property type, how the title is held, the borrower’s credit, and how much debt already sits on the property.

NerdWallet notes that an investment-property HELOC is harder to get than one on a primary home, because lenders see higher default risk. Not every lender offers it, and the requirements run strict. That matches what the wholesale side shows: investment lines are a narrow product with tighter terms than primary-residence lines.

Provider types that write this product include credit unions, community and regional banks, portfolio lenders, and wholesale channels that a broker can access. Each qualifies the borrower differently. A broker’s value is comparing several programs against one scenario instead of testing them one application at a time.

Key Terms Defined

HELOC: An open-end line of credit secured by a property. The borrower can draw, repay and draw again within the draw period.

CLTV: Combined loan-to-value. It adds every lien on the property, including the new line, and divides by the property’s value.

Lien position: The order in which lenders are repaid if the property is sold. A first lien is repaid before a second.

Construction-to-permanent loan: A single loan that pays for the build and then converts to a long-term mortgage.

Seasoning: The time a loan, a title or a deposit has been in place before a lender treats it as established.

Certificate of occupancy: The local sign-off that a finished building can be lived in. Lenders typically want it before they lend against a new build.

What a HELOC Is and Is Not

The CFPB describes a HELOC as an open-end line that lets a borrower draw repeatedly against equity. It also explains that a draw period can run 10 years, followed by a repayment period of 10 or 20 years. Payments are often significantly higher once repayment begins.

That payment step-up matters to an investor sizing a rental on its cash flow. Interest-only payments during the draw period flatter the numbers. The amortizing payment later does not.

Investment lines on the network follow a 5-year draw and a 25-year repayment, with at least 75% of the line drawn at closing. Pricing floats across both periods and never converts to fixed. A borrower modeling a hold period should model the repayment period, not just the draw.

The Sequence: Construction Loan First, Line Second

The order below is how the pieces typically fit together on a new build.

1. Build under the construction loan. Draws fund the work, and payments are interest-only during construction. A construction-to-permanent loan then converts to a long-term mortgage. A construction-only loan is repaid by a separate takeout.

2. Complete and document the property. The lender will want the certificate of occupancy, a final value and, usually, a lease or rent evidence.

3. Pay off or convert the construction loan. Until this happens, the construction lender holds the first lien. A new line has nowhere to sit.

4. Choose the permanent first mortgage. A DSCR loan is a common exit on a leased rental. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Our complete DSCR loans guide covers how those files are built.

5. Add the line, if the numbers still allow it. The line can sit in first or second position. If a first mortgage already exists, the combined leverage has to fit under the CLTV ceiling.

The point of the order is simple. A line is a post-completion tool, and it is the wrong product for funding drywall.

How Underwriting Treats a Newly Built Rental

A HELOC is underwritten on the borrower, not on the rent. A DSCR loan is the reverse. That contrast drives most of the decisions here.

On the network’s investment lines, these are the main tests:

• Credit: 700 minimum, with 720 and 700 both reaching the same 70% CLTV ceiling. Credit above 700 buys eligibility, not extra leverage.
• Leverage: a 70% CLTV ceiling on an investment property. Market surveys of investment HELOCs report higher figures at some lenders. Those describe the broader market. The network figure for an investment line is 70%.
• Line size: $25,000 to $750,000 across the products overall, but an investment line tops out at $500,000. Anything above $500,000 is primary-residence only.
• DTI: 50% maximum, with lower limits for weaker credit profiles. The qualifying payment is the interest-only payment on the maximum draw.
• Valuation: because an investment line caps at $500,000, it commonly runs on an automated valuation instead of a full appraisal. A borrower may still request a full appraisal. On a brand-new build, thin comparable sales can matter more than they would on an older house, so it is worth asking early how value will be set.
• Exposure: a borrower is limited to three lines, and an owner with more than 15 financed properties is not eligible.

Seasoning on a new build is mostly a lender-by-lender matter. No reliable public standard exists, so a broker asks each program directly how it treats a property with a recent completion date and a recent note.

Title and Ownership: Where Builders Get Stuck

Many builders hold their rentals in an LLC. On the network’s HELOC programs, that is the sharpest structural problem.

Title must be held by the individual borrower or by an inter vivos 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 before a line is possible, or a DSCR cash-out refinance instead.

That is why the title decision belongs before the build closes, not after. A builder who knows a line is part of the plan can set up the vesting with that in mind. Lender policy on LLCs varies across the broader market, so some outside lenders may behave differently. Within this network the rule is firm.

The three vesting paths look like this:

Documenting Income When You Are Self-Employed

Builders are often self-employed, which changes the documentation path. Business bank accounts require a 680 minimum for the deposit analysis. Investment lines already floor at 700, so bank-statement income is never the binding constraint on an investment line. A self-employed borrower is reviewed on documented income under the applicable program, subject to lender guidelines. The usual evidence is a clean credit report, a lease or rent history on the property and bank records that fit the stated income.

A rental still in lease-up has little rent history. A signed lease helps. A vacant new build may fit better with a DSCR loan that uses market rent, a different product than a line.

Line, Cash-Out Refinance or DSCR: Which Fits?

Cash-out on standard rentals tops out around 75% LTV across most of the network, with about 6 months of seasoning as a common expectation. Short-term-rental collateral is lower, at 70% on cash-out. A line’s 70% CLTV ceiling is lower than the standard-rental cash-out ceiling. That gap can decide the choice on a property with a lot of equity. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

A Worked Example

Consider a builder who completes a rental and holds it in a revocable trust. The property has a certificate of occupancy and a signed lease. The construction loan converts to a permanent first mortgage.

• The credit profile is 720.
• The first mortgage plus the new line must stay at or under 70% CLTV.
• The line sits at or below $500,000, so an automated valuation is likely.
• The line runs a 5-year interest-only draw followed by a 25-year repayment period, with at least 75% of it drawn at closing.

If the first mortgage already uses most of the 70% allowance, the line has little room. In that case the investor either asks for a smaller line or looks at a cash-out refinance at higher leverage. Run the combined number before applying, not after. Stacking debt can also strain the property’s own coverage ratio if the second-lien payment is counted, so check both tests: enough equity and enough rent.

Edge Cases That Break the General Rule

• Construction-to-permanent loans. A line can be added only after conversion, and only if the permanent loan allows a junior lien. Check its subordinate-financing terms.
• Property type. Single-family, 2-4 units, PUDs, townhomes and condominiums are eligible. Manufactured homes, co-ops, condotels, log homes, commercial and mixed-use properties are not.
• Listed property. A property listed for sale, or listed within the past 60 days, is ineligible in Indiana, North Carolina, Pennsylvania, Tennessee, Texas and Washington.
• Texas. Investment properties are eligible as non-homestead transactions, and Texas properties are limited to 10 acres.
• Geography. Lines are available only in the 16 full-service states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA.
• Derogatory history. A bankruptcy needs 4 years of seasoning. Investment files follow a 7-year foreclosure and 4-year short-sale path.

Pre-Application Checklist

• Certificate of occupancy and final construction-loan payoff or conversion documents
• Recorded deed showing the borrower’s name or revocable trust
• Signed lease or rent evidence
• First-mortgage statement showing the balance
• Credit report no more than 90 days old at closing
• Bank statements and income documents for the self-employed path
• Insurance declarations for the finished property

Risks Investors Should Price In

The line’s pricing floats and never converts to fixed. The payment steps up when repayment starts, as the CFPB explains. Combined leverage rises with each lien, which cuts future cash-out capacity. Lenders can also tighten or freeze availability, so a line should be treated as a tool, not a guaranteed reserve. 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.

A DSCR loan is the steadier choice when predictability matters. It is fixed-term and qualifies primarily on property-level rental income, subject to lender guidelines. DSCR compares rent to the full payment only. Clearing that test is not the same as positive cash flow, since repairs, vacancy and management sit outside the ratio.
