Banks That Offer a HELOC for Credit Lines Above Half a Million Dollars

The Quick Read: A line above $500,000 is a niche, portfolio-style product, and on the select wholesale lenders Lendmire works with it is available only on a primary residence, at up to 75% combined loan-to-value, with a full appraisal and a credit profile of 700 or better (720 on the longer-runway program, which carries a five-year interest-only draw). Rental properties on that network cap at $500,000 and 70% CLTV, so investors who want a larger pull against a rental usually end up in a DSCR cash-out refinance instead.

• No law sets a $500,000 ceiling. It is a lender habit, and many banks stop there because larger lines are harder to sell on the secondary market.
• A larger line is underwritten on your personal credit, income, and debt-to-income ratio, not on rental income.
• LLCs, corporations, and partnerships cannot hold title on these lines.
• Qualification is subject to lender guidelines and full file review. This is not a commitment to lend.

What Counts as a HELOC Above $500,000?

A HELOC above $500,000 is a revolving home equity line whose limit exceeds the size most banks will write. Lenders often call it a jumbo line. The label is informal. No regulator defines “jumbo” for equity lines.

Here is how the product works in plain terms. You borrow against equity, which is the home’s value minus what you owe on the first mortgage. You draw funds as needed during a set period. Then you repay the balance over a longer period. A line can sit in first-lien or second-lien position, depending on whether a first mortgage already exists.

The question “which banks offer one” has a narrower answer than most searchers expect. Large retail banks tend to write standard lines and stop at a modest ceiling. Larger lines tend to come from private banks, credit unions with balance-sheet appetite, and portfolio lenders. Those lenders keep the loan instead of selling it. A mortgage broker like Lendmire does not hold loans. It compares programs across a network of wholesale lenders and matches the file to the one whose guidelines fit.

Why Most Banks Stop at $500,000

Most lenders cap lower because a line this size is harder to package and sell. A bank that keeps the loan takes on the risk itself. So it asks for more equity, stronger credit, and a full appraisal.

The practical effect is a split. Standard lines are easy to find, and larger lines are a relationship product. Whether a lender writes one depends on the borrower’s situation: occupancy, credit profile, how much equity remains after all liens, and how the property is titled. The lenders that write this product vary, and so does the best fit for any one borrower.

Investors hit a second wall. Most jumbo-line marketing assumes the collateral is the borrower’s own home. Lenders get far more cautious when the collateral is a rental, and many write nothing there at all.

How Underwriting Treats a Large Line, Step by Step

Underwriting a large line follows seven steps, and occupancy decides the answer at nearly every one. The sequence below reflects how the programs in Lendmire’s wholesale network handle it.

1. Pick the collateral. The line is secured by a primary residence, a second home, or an investment property. Each carries different limits, shown in the table below.

2. Run the equity math. The CFPB’s HELOC booklet describes the standard method. The lender applies a percentage to the appraised value, then subtracts what you owe. The result is your maximum line.

3. Qualify the borrower. Underwriting looks at credit score, income, and debt-to-income. The maximum DTI is 50%, and it drops to 45% for credit profiles from 600 to 679. A ratio above 45% requires at least a 680 score. The debt test uses the interest-only payment calculated on the maximum draw, not on what you plan to borrow.

4. Value the property. Lines at or below $500,000 ordinarily run an automated valuation. A full appraisal is required on every line above $500,000, and any borrower may request one.

5. Check credit depth. The credit report cannot be more than 90 days old at closing, and no rescores are allowed. The longer-runway program also wants two tradelines seasoned 12 months or one seasoned 24.

6. Choose the draw structure. The longer-runway program gives a five-year interest-only draw followed by a 25-year fully amortizing repayment. A shorter-draw program gives a three-year draw with 17 years of repayment. At least 75% of the line is drawn at closing. Pricing floats through both periods and never converts to fixed.

7. Draw, then repay. After closing, a minimum subsequent draw applies, commonly $1,000 on the longer-runway program. The CFPB explains that a HELOC is secured by your home, so missed payments put the home at risk.

Here is a percentage-only example of the equity math in step 2. Say a primary residence qualifies at 75% CLTV, and the existing first mortgage equals 40% of appraised value. That leaves room equal to 35% of value. For a line above $500,000, the home would need to be worth nearly three times the line you want. Thin equity is the most common mismatch between what borrowers hope for and what the math allows.

What the Network’s Programs Allow, by Occupancy

Limits depend on occupancy, and the gap between a primary residence and a rental is wide. Figures below are typical ranges from the select wholesale lenders in the network, subject to lender guidelines.

A line above $500,000 is available on a primary residence only. It requires a credit profile of 700 or better (720 on the longer-runway program). It caps at 75% CLTV and requires a full appraisal. The 90% ceiling in the table applies only to lines up to $500,000 at 720 or higher; a 700 profile on a primary residence reaches 75% CLTV on the larger line, or 85% on a line up to $500,000.

Primary residences and second homes can use either the three-year or the five-year draw structure. Investment lines, by contrast, run the five-year draw and 25-year repayment structure only.

Other eligibility points:

• Eligible properties include single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, log homes, commercial, mixed-use, and agricultural-zoned properties are not offered.
• A bankruptcy needs four years of seasoning from discharge or dismissal. Foreclosure history splits by program: one seasons a foreclosure at seven years, and the other declines that history entirely.
• A borrower is limited to three lines, and a borrower with more than 15 financed properties is not eligible.
• This product is offered only in Lendmire’s 16 full-service states, which is narrower than its 41-market DSCR footprint.

Where the General Rule Breaks

The general rule is that bigger lines go to owner-occupants with deep equity. Several situations bend it.

Rental collateral. The same borrower may qualify for a large line on a primary residence and be capped at $500,000 on a rental. Using the home as collateral for rental investing also puts the home behind the rental’s risk. That is a real tradeoff, and some investors decide the exposure is not worth it.

LLC-held rentals. Title must sit with the individual borrower or a revocable living trust. LLCs, corporations, partnerships, and irrevocable, blind, or land trusts cannot hold title. A property already deeded to an LLC needs either a vesting change or a DSCR cash-out instead, subject to program terms.

Lease restrictions. Some line agreements restrict renting out the home that secures the line. That matters for house-hackers and anyone planning to convert a primary residence into a rental. Read the agreement before you draw.

Lien sequencing. A standalone line can sit in first or second position. If you may refinance the first mortgage later, a second lien on the same property adds a step, and the new lender must work around it. Stacking liens also shrinks the equity left for any later refinance.

Short holds. A floating-price line fits best when you expect to repay in months, such as a renovate-and-refinance plan. Holding a large balance for years on a floating line is a different risk. The draw-period payment is interest-only on many products. Principal begins to amortize after the draw ends, and the payment can step up sharply. Lenders can also reduce or freeze a line if the home’s value falls, so do not treat the line as guaranteed to stay open.

If you plan to use proceeds on a rental, note that tax treatment can depend on how the funds are used and how the property is held. Keep clear records and speak with a qualified tax professional before relying on any deduction.

HELOC or DSCR Cash-Out? The Decision in Practice

The answer turns on three things: where the collateral sits, how it is titled, and how much you need to pull. A line works when you own the home personally, hold deep equity, and want staged access. A cash-out works when the rental is the asset and you want a rent-qualified loan.

Here is how a DSCR cash-out works across the network. It compares the property’s rent to its full monthly obligation: principal, interest, taxes, insurance, and any HOA dues. Cash-out refinances top out around 75% LTV on most programs, with about six months of seasoning as the common expectation. Credit floors start at 620 in parts of the network. Most programs want around 660, and 700 or more unlocks the strongest leverage tiers. Loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders. Above $2,500,000 the network generally holds to 30-year fixed structures. Reserves vary by lender, leverage, and loan size, and are commonly around six months.

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. Clearing 1.00 does not mean the property cash flows, because repairs, vacancy, management, utilities, and capex sit outside the calculation. Lendmire’s complete DSCR loans guide walks through the full mechanics.

A DSCR cash-out replaces your first mortgage, so the new loan’s cost applies to the whole balance. A line leaves the first mortgage in place and adds a second payment your DSCR ratio will not see but your bank account will. Run the blended cost across both structures before you choose.

Key Terms Defined

Combined loan-to-value (CLTV): All loans secured by the property, including the new line, divided by its appraised value.

Draw period: The stretch of time when you can borrow from the line, often interest-only.

Repayment period: The later stretch when you can no longer draw and the balance amortizes.

Lien position: Whether a loan is paid first or second if the property is sold or foreclosed.

Vesting: The name or entity on the property’s title.

Debt-to-income (DTI): Your monthly debt obligations divided by your gross monthly income.

DSCR: Monthly rent divided by the property’s full monthly obligation (PITIA), the test used on investor loans.

Questions to Ask Any Lender Before You Apply

Limits and guidelines change, so confirm them directly before you apply. These questions surface the deal-breakers early:

• Is the collateral eligible by occupancy, property type, and title?
• What is the maximum CLTV at my credit profile, and does it differ above $500,000?
• Is a full appraisal required, and who orders it?
• How is the payment calculated for qualification: on the amount drawn, or on the maximum line?
• What share of the line must be drawn at closing?
• Can the lender freeze or reduce the line, and under what conditions?
• Is the line first-lien or second-lien, and how does that affect a future refinance?

Next Steps

If you are considering a home equity line and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. Lendmire arranges financing through select wholesale lenders in its network, and DSCR programs are available. Many investors find the answer sits between a line on their home and a cash-out on the rental, and a short comparison of both usually settles it.
