Banks That Offer an Investment Property HELOC With the Highest Available Borrowing Limits

The Quick Read: On a rental property, the largest line available through the wholesale lenders Lendmire works with is $500,000 at up to 70% combined loan-to-value, and your real limit is whichever is smaller: that cap, or 70% of the property’s value minus what you already owe. No honest ranking of banks by limit exists, because each lender sets its own policy and the right fit depends on your file. Lendmire is a mortgage broker, not a lender, so it shops the scenario across lenders instead of pushing one.

• On an investment property, the network ceiling is 70% CLTV (combined loan-to-value, all liens against value).
• The maximum investment line is $500,000. Any larger line is reserved for primary residences.
• The minimum credit score on an investment line is 700, and 720 buys no extra leverage.
• The property must be titled to you personally or to your revocable living trust. An LLC cannot hold title.
• If you need more capacity than a HELOC allows, a DSCR cash-out refinance is the usual next option.

Which Banks Offer the Highest Limits?

No neutral, current ranking of banks by investment-property HELOC limit exists. Any list claiming to name the top bank deserves suspicion.

Here is what is true. Few large retail lenders write lines on rentals at all. NerdWallet reports that not every lender offers them and that qualifying is strict. The lenders that do write them each set their own combined-loan-to-value ceiling and their own dollar cap. No single rule sets either number.

So the question to ask is not which bank is biggest. Ask which lender’s rules fit your property, your credit, your title, and your existing mortgage. The lenders that write your scenario depend on those facts.

Lenders that hold loans on their own books can flex more than lenders that follow one national policy. Flex is not a promise, though. Always get the cap and the ceiling in writing from whoever you apply with.

What the Network Allows on an Investment Line

Through select wholesale lenders in Lendmire’s network, an investment-property line tops out at $500,000. The ceiling is 70% CLTV. The minimum credit score is 700. Those are the headline numbers, and everything else shapes how much of them you can use.

NerdWallet cites investment-property HELOCs that typically ask for credit near 720 and at least 20% equity. That is a market-wide figure. The network figure is the 700 floor and 70% CLTV ceiling above.

Other terms on an investment line, all subject to lender guidelines and full file review:

• Credit tiers. A 720 score and a 700 score both reach 70% CLTV up to $500,000. Credit above 700 buys eligibility, not extra leverage.
• Structure. The line sits in first or second lien position. It runs a 5-year interest-only draw, then a 25-year fully amortizing repayment.
• Draw at closing. At least 75% of the line is drawn at closing. This is not a standby cushion you leave untouched.
• Pricing. It floats through both the draw and repayment periods and never converts to fixed.
• Debt-to-income. The ceiling is 50%, tested on the interest-only payment at the maximum draw.
• Valuation. Because the line caps at $500,000, it ordinarily runs on an automated valuation with no traditional appraisal. A higher CLTV can trigger a second valuation, and you may ask for a full appraisal.
• Availability. These lines are written in Lendmire’s 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, which includes Washington, D.C.

How Is the Maximum Line Calculated?

The limit is a percentage of your property’s value, minus what you owe. The CFPB’s HELOC booklet describes the same method: take a percentage of the appraised value, then subtract your debt. On this network’s investment tier, that percentage is 70%.

Walk through it in steps:

1. Value. Start with the property’s valued amount. Call it 100%.

2. Ceiling. Multiply by the 70% CLTV ceiling. That leaves 70% of value for all liens combined.

3. Subtract liens. Your first mortgage uses room first.

4. Apply the cap. Compare the remainder to the $500,000 maximum. The smaller figure controls.

Run the numbers on a rental with a first mortgage at 55% of value. Subtracting from the 70% ceiling leaves a line of 15% of value. Take a second rental with a first mortgage at 40% of value: the same subtraction leaves a line of 30% of value, still subject to the $500,000 cap. That cap only bites on higher-value, low-leverage properties. For most rentals, the equity formula binds first.

This is why a bigger advertised limit does not mean bigger usable capacity. The first mortgage balance decides most of it. Also, the full line counts against the ceiling, not just what you draw. Combined loan-to-value includes the entire new limit.

Key Terms Defined

• CLTV (combined loan-to-value). All loans secured by the property, including the full new line, divided by its value.
• Lien position. Whether a loan gets paid first (first lien) or after another mortgage (second lien).
• Draw period. The stretch when you can borrow from the line and pay interest only.
• Repayment period. The stretch after the draw, when you pay down principal and interest on the balance.
• Automated valuation. A computer-generated value estimate used in place of a full appraisal.
• Vesting. The name or entity that holds legal title to the property.

Where the General Rule Breaks

Several edge cases change your limit or remove it altogether.

Title held by an LLC. This is the sharpest edge. An LLC, corporation, partnership, or irrevocable, blind, or land trust cannot hold title on these lines. Only you personally or your revocable living trust can. If the property is already deeded to an LLC, the options are a vesting change or a DSCR cash-out instead, subject to program terms.

Property type. Eligible: single-family, 2-4 units, PUD, townhome, and condominium, including non-warrantable condos. Not offered: manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned property.

Portfolio size. You are limited to three lines. An investor owning more than 15 financed properties is not eligible.

Credit history. A bankruptcy needs 4 years of seasoning from discharge or dismissal. On an investment property, a foreclosure needs 7 years, and a deed-in-lieu, pre-foreclosure, or short sale needs 4.

Selling the property. The CFPB notes you generally must pay the line off in full if you sell.

Lines above $500,000. These exist only on primary residences, cap at 75% CLTV, and require a full appraisal. A rental cannot use them.

Investment HELOC vs. Other Ways to Pull Equity

A HELOC leaves your existing first mortgage in place. The CFPB describes a HELOC as an open-end line you can borrow against repeatedly, with a draw period followed by repayment. The choice among products comes down to what each one underwrites and how much it can reach.

For larger needs, a DSCR cash-out refinance on a standard rental typically tops out around 75% LTV across most of the network, with about 6 months of seasoning common. 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. Most programs want a score around 660, a 620 floor exists in parts of the network, and 700+ opens the strongest tiers. Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines.

Clearing 1.00 does not mean positive cash flow. The ratio compares rent to the payment only. Repairs, vacancy, management, and utilities sit outside it. The complete DSCR loans guide covers the mechanics in full.

Who Fits Which Product?

An investment HELOC tends to fit an investor who has:

• Strong personal credit and debt-to-income under 50%.
• A modest first mortgage, so the 70% ceiling leaves real room.
• The property titled in a personal name or revocable trust.
• A need under $500,000, and a plan to draw most of it soon, since 75% is drawn at closing.

A DSCR cash-out tends to fit an investor who:

• Holds rentals in an LLC.
• Carries heavy personal debt or many financed properties.
• Needs a larger amount than $500,000 allows.
• Prefers to qualify on the rent instead of personal income.

How to Get the Largest Line You Can

Stage the request before you apply.

1. Pull your first mortgage balance. It decides most of your capacity.

2. Check title. Confirm it sits in your name or a revocable trust.

3. Know your credit. The floor is 700. Rescores are not available on these lines, so fix problems before applying.

4. Calculate debt-to-income. Remember lenders test the interest-only payment on the maximum draw.

5. Confirm property type and portfolio count. Check against the eligibility list above.

6. Price the alternative. Compare the HELOC to a DSCR cash-out before choosing.

Plan for the end of the draw period too. Payments change at the 5-year mark when repayment begins, and pricing floats throughout.
