Banks That Offer a HELOC for a $500K Credit Line Amount

The Quick Read: A $500K line is an outcome of equity, credit, and debt load, not a product any bank advertises as a fixed amount. Lenders that write lines this size are limited, and the amount you can actually draw depends on how much equity remains after existing liens.

• Large national banks often restrict or skip rental-property lines, so supply is thin.
• On an investment property, the network ceiling is 70% combined loan-to-value (CLTV), with a 700 minimum credit profile and a $500,000 maximum line.
• On a primary residence, lines above $500,000 run up to $750,000 and require a 700 or better credit profile (720 on the longer-runway structure).
• Rent does not size a HELOC. Value, existing debt, credit, and debt-to-income do.
• The right program depends on the property, the equity, and the credit profile, not on a bank’s name.

Every figure below is subject to lender guidelines and full file review. Nothing here is a commitment to lend.

What Does a $500K HELOC Actually Require?

A $500K line requires a lot of equity. Lenders take the property’s value, multiply by the maximum combined loan-to-value, and subtract existing liens. What remains is the most the line can be, before credit, income, and program dollar caps trim it further.

Run the arithmetic as a modeled example. Required value equals existing liens plus the $500K line, divided by the CLTV ceiling. With no first mortgage and an 80% ceiling, the property needs to be worth about $625K. Each dollar of existing mortgage debt raises that requirement by $1.25 at that ceiling. At a 70% ceiling, the investment-property tier in Lendmire’s network, the bar is higher still. A $500K line with no first mortgage then needs a property worth roughly $715K.

Most lenders count the full credit limit in the CLTV test, not just the drawn balance. So an undrawn line still uses up equity on paper.

How Underwriting Treats a Large Line, Step by Step

Underwriting follows a fixed sequence, and the smallest limit in the sequence sets your line.

1. Pick the collateral. The line sits on your primary home with the funds going to a rental purchase or rehab, or it sits on the rental itself. The risk differs: a primary-home line puts your residence behind the debt, while a rental-collateral line strains rental cash flow.

2. Value the property. On the network’s programs, lines at or below $500,000 ordinarily run an automated valuation with no traditional appraisal. A higher CLTV may require a secondary valuation, and a borrower may request a full appraisal in any case. Every line above $500,000 requires a full appraisal.

3. Compute CLTV. First mortgage plus other liens plus the new line, divided by value.

4. Test credit and debt-to-income. The network’s programs set a 50% maximum debt-to-income ratio, with 45% for credit profiles from 600 to 679. A ratio above 45% requires a 680 minimum. The qualifying payment is the interest-only payment calculated on the maximum draw, so a large line is tested as if fully drawn.

5. Document the file. Expect proof of income, tax returns, rental agreements, and proof of property insurance, as Benzinga’s investor-written overview lists them. For a HELOC, rent supports the file as documentation. It is not the qualifying ratio the way it is on a DSCR loan.

6. Close and draw. On the network’s programs, at least 75% of the line is drawn at closing. After that, the minimum subsequent draw is $1,000 on the longer-runway structure, with Texas at $4,000.

The usable line is the smallest of what CLTV, the program’s dollar cap, and debt-to-income capacity allow.

Which Banks Offer This? (The Honest Answer on Supply)

Availability is the real constraint. NerdWallet says a HELOC on an investment property is not offered by all lenders, comes with strict qualification requirements, and is sometimes restricted by location or by whether the home is rented all year. A practitioner view from Taxstra adds that most large national banks either do not offer investment-property lines or restrict them heavily, leaving portfolio lenders, credit unions, and regional banks as the limited-supply sources.

This article does not rank or name institutions. The lender that writes a $500K line depends on the property type, occupancy, credit profile, and how much equity is left after the first mortgage. Lendmire is a mortgage broker, not a lender.

Lendmire’s equity-line placements are available in 16 full-service states only (AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA, WA). That is narrower than the 41-market DSCR footprint, which covers 40 states plus Washington, D.C.

Network Ceilings by Occupancy

Ceilings are tiered by occupancy, and the investment tier is the lowest. Applying a primary-residence figure to a rental is an easy way for a $500K expectation to fall apart.

Several details sit behind that table:

• On an investment property, 70% is the ceiling at both the 700 and 720 tiers. There is no tier above it.
• On a second home, the credit floor is 640, but 90% CLTV exists only at a 720 or better profile. Lower credit tiers are held to a lower CLTV than that top tier.
• On a primary residence, the credit floor is 600, and a profile that low is held to a much lower CLTV than the top tier. The 90% ceiling also requires 720 or better and caps the line at $500,000. A line above $500,000 is primary-residence only, requires a 700 or better credit profile (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal.
• A Texas primary residence is a homestead and caps at 80% combined loan-to-value, so the higher matrix tiers never apply there. Texas second homes and investment properties are eligible as non-homestead transactions.

Market sources may quote other figures for equity lines, but those describe the broader market, not this network. For an investment property here, the number is 70%.

How Do the Draw and Repayment Periods Work?

The structure is a standalone line in first or second lien position. The CFPB explains that you can generally spend up to your limit during the draw period, and that HELOCs usually carry variable pricing, so payments may change from month to month. Some HELOCs let you convert part of the balance to fixed. The network’s lines do not convert; pricing floats through both the draw and repayment periods.

Two draw structures exist on primary residences and second homes:

• A 3-year interest-only draw followed by a 17-year fully amortizing repayment.
• A 5-year interest-only draw followed by a 25-year fully amortizing repayment, which this article calls the longer-runway structure.

Tennessee shortens both: the 3-year draw pairs with a 12-year repayment, and the 5-year draw pairs with a 10-year repayment. Investment lines run the 5-year draw and 25-year repayment structure only.

The step-up matters. During the interest-only draw, the payment covers interest alone. When repayment starts, the payment amortizes the principal as well, and on a $500K balance that is a visible jump. A rental whose income stays flat has to absorb it.

Where the General Rule Breaks

The standard path breaks in specific, predictable places.

Vesting in an LLC. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title on these lines. Only the individual borrower or an inter vivos revocable living trust can. This is the sharpest structural difference from a DSCR loan. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out refinance, subject to program terms.

Property type. Single-family, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable condos, are eligible. The 2-4 unit tier carries a 640 minimum on the longer-runway program. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural zoning are not eligible.

Portfolio size. A borrower is limited to three lines. Combined exposure caps at $2,000,000 on the higher-leverage program and $750,000 on the longer-runway program. A borrower with more than 15 financed properties is not eligible.

Credit events. A bankruptcy needs 4 years of seasoning from discharge or dismissal. Foreclosure history splits by occupancy: investment files follow a 7-year path for a foreclosure and 4 years for a deed-in-lieu, pre-foreclosure, or short sale, while one program declines foreclosure-family history entirely on primary and second-home files.

Listings. A property listed for sale, or listed within the past 60 days, is ineligible in NC, PA, TN, TX, and WA.

Shrinking lines. The CFPB’s HELOC brochure notes that lenders may reduce or freeze a line if the home’s value falls. A $500K line is not guaranteed capacity for the full draw period. Lendmire’s piece Banks That Offer a DSCR HELOC When a Lender Freezes or Reduces the Credit Line covers that scenario.

Key Terms Defined

Combined loan-to-value (CLTV): the total of all liens on the property, including the full new credit limit, divided by the property’s value.

Draw period: the window when you can borrow against the line, usually interest-only on these programs.

Repayment period: the stretch after the draw ends, when the balance amortizes with principal and interest.

Debt-to-income (DTI): your monthly debt obligations divided by your monthly income, used to size what you can carry.

DSCR: a ratio of a property’s rent to its monthly obligation (principal, interest, taxes, insurance, and any HOA dues). It sizes DSCR loans, not HELOCs.

When $500K Is More Than the Property Can Carry

Many investors hit the CLTV ceiling before they hit the dollar cap. Picture an investor with a rental worth $800K and a first mortgage that already takes a large share of the value. At a 70% ceiling the combined debt tops out at $560K, so the existing first lien uses up part of that room, and the line may land well below $500K depending on the first mortgage balance. In that case equity, not the dollar cap, sets the limit.

Several paths exist when the line comes up short.

• Use a different property as collateral. A primary residence carries a higher ceiling than a rental, and a line above $500,000 is available only there.
• Use a DSCR cash-out refinance. This replaces the existing mortgage with a larger one and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Cash-out leverage across the network tops out around 75% LTV on a standard rental, with about 6 months of seasoning as the common expectation. NerdWallet names this and a DSCR second mortgage as options for rental owners.
• Weigh the first mortgage. A second lien sits behind the first. If the first mortgage terms are worth keeping, a line preserves them. If not, a cash-out refinance may serve better.

For a DSCR cash-out, the coverage test is separate from the equity test. Clearing 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. The strongest files clear both tests: enough equity and enough rental coverage. Clearing the ratio is not the same as positive cash flow, because repairs, vacancy, management, and capex sit outside the calculation. For the full mechanics, see Lendmire’s complete DSCR loans guide.

Risks of a Large Variable-Rate Line

A variable line on a rental carries three risks worth sizing before applying.

• Payment shock. Floating pricing means payments can rise while rental income stays flat. Stress-test the payment at the maximum draw, which is also how the network qualifies the file.
• Collateral risk. Benzinga notes that missed payments risk foreclosure on the investment property and that the line adds to your overall debt load.
• Line reductions. A drop in value can shrink capacity just when you want to use it.

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.

What to Prepare Before You Ask

• Confirm your titling: the property must be held by you as an individual or by a revocable trust, not by an LLC.
• Have a credit report that is current at closing, and expect no rescores. The network uses a single-bureau score keyed to the primary wage earner.
• Show two tradelines seasoned 12 months or one seasoned 24 on the longer-runway program, and keep your housing history clean across all financed properties.
• Gather your lease agreements, proof of insurance, and income documents.
• Prepare a current list of every lien on the property and every financed property you own.
