Homeowners with substantial equity may be able to access a significant amount of cash without selling their property.
For homeowners with expensive properties and relatively low mortgage balances, that available equity can potentially be used for major renovations, business purposes, investment opportunities, education expenses, debt consolidation or other large financial needs.
In 2026, home-equity financing remains a significant lending market. As of September 16, 2026, Bankrate’s national average HELOC rate was 7.11%, while its national average home-equity-loan rate was 8.15%. Actual rates vary based on credit, loan amount, combined loan-to-value ratio, property, lender and other factors.
For homeowners with substantial equity, the borrowing opportunity can be much larger than the typical $30,000 or $50,000 home-equity loan often discussed online.
Some lenders offer home-equity products with maximum amounts of several hundred thousand dollars, while larger borrowing needs may require specialized lenders, private banking, cash-out refinancing or other financing structures.
This guide explains how $500,000 to $1.5 million home-equity financing works, how much equity you may need, how HELOCs compare with home-equity loans, what lenders look for, and which financing structures may be relevant for large borrowing amounts.
What Is a Home Equity Loan?
A home equity loan allows a homeowner to borrow a specific amount of money against the equity in their property.
Your equity is generally the difference between the current value of your home and the amount you owe on existing mortgages.
For example:
Home value: $2,000,000
Existing mortgage: $500,000
Approximate equity: $1,500,000
However, having $1.5 million in equity does not automatically mean you can borrow $1.5 million.
The lender will normally consider the property’s value, existing mortgage balance, credit profile, income, debt obligations and maximum combined loan-to-value ratio.
A home-equity loan generally provides a lump sum, while a HELOC provides a revolving credit line that can be accessed during the draw period.
What Is a HELOC?
A HELOC, or home equity line of credit, is a revolving credit line secured by your home.
Instead of receiving the entire amount at once, you generally receive a maximum credit limit and can borrow from that available balance during the draw period.
For example, if a lender approves a $500,000 HELOC and you initially use $100,000, you generally pay interest based on the amount actually borrowed rather than the entire $500,000 limit.
As you repay the balance, available credit can generally become available again during the draw period.
The Consumer Financial Protection Bureau describes a HELOC as an open-end line of credit that allows borrowers to repeatedly borrow against available home equity.
Because your home serves as collateral, failure to repay the debt can put the property at risk.
How Much Can You Borrow Against Your Home?
The maximum amount depends on the lender’s combined loan-to-value requirements and your existing mortgage balance.
A simplified example:
Home value: $2,000,000
Maximum combined LTV: 80%
Maximum total secured debt: $1,600,000
Existing mortgage: $500,000
Potential additional borrowing: approximately $1,100,000
This is only an illustration.
Some lenders may use lower or higher maximum CLTV limits depending on the borrower and property.
Bankrate notes that lenders commonly allow borrowing up to around 80% of home value minus the existing mortgage, while some lenders may go as high as 85% or 90%.
For very large loans, however, the available programs can become more specialized.
Example: How a $500K Home Equity Loan Could Work
Suppose your home is worth $1.5 million.
You currently owe $500,000.
Your approximate equity is:
$1,500,000 − $500,000 = $1,000,000
If a lender permits total debt up to 80% of the home’s value:
80% × $1,500,000 = $1,200,000
After subtracting the existing $500,000 mortgage:
$1,200,000 − $500,000 = $700,000
Under this simplified example, the theoretical maximum additional borrowing would be approximately $700,000.
That does not mean the lender will approve $700,000.
Income, credit, debt-to-income ratio, property type, loan purpose, reserves and lender-specific rules can reduce the amount.
Example: How a $1 Million HELOC Could Work
Consider a homeowner with:
Home value: $2.5 million
Existing mortgage: $400,000
Approximate equity: $2.1 million
At an 80% combined loan-to-value limit:
80% × $2.5 million = $2 million
Subtracting the existing mortgage:
$2 million − $400,000 = $1.6 million
The theoretical equity available under that simplified calculation would be $1.6 million.
However, finding a lender willing to provide a $1.6 million HELOC is a different matter.
Large home-equity lines can require specialized underwriting and may not be available through lenders whose standard HELOC products have substantially lower maximum limits.
Can You Get a $500K Home Equity Loan?
A $500,000 home-equity loan is possible for some borrowers, but approval depends on the lender and financial profile.
For example, current Bankrate-listed HELOC products include maximum loan amounts of $700,000 and $750,000 from some providers, while other products have substantially lower limits.
Home-equity loans can also have lower maximum amounts depending on the lender.
A $500,000 request may therefore require comparing multiple lenders instead of applying to only one bank.
Can You Get a $1 Million Home Equity Loan?
A $1 million home-equity loan is considerably more specialized.
The borrower would typically need substantial equity and sufficient income or other qualifying financial strength.
For example:
| Home Value | Existing Mortgage | Approx. Equity | 70% Total LTV | 80% Total LTV |
|---|---|---|---|---|
| $1,500,000 | $300,000 | $1,200,000 | $750,000 additional | $900,000 additional |
| $2,000,000 | $300,000 | $1,700,000 | $1,100,000 additional | $1,300,000 additional |
| $2,500,000 | $500,000 | $2,000,000 | $1,250,000 additional | $1,500,000 additional |
| $3,000,000 | $500,000 | $2,500,000 | $1,600,000 additional | $1,900,000 additional |
These are mathematical illustrations, not lender offers or guaranteed borrowing limits.
The actual maximum can be lower because lenders may impose their own CLTV, credit, income and loan-size restrictions.
Can You Borrow $1.5 Million Against Your Home?
A $1.5 million home-equity loan or HELOC may be possible for some high-equity homeowners, but this moves into a much more specialized part of the lending market.
A homeowner looking for $1.5 million in equity financing may need to investigate:
- Jumbo home-equity products
- Private-bank lending
- Portfolio lenders
- Large HELOC programs
- Cash-out refinancing
- Securities-backed lending
- Other secured financing
The appropriate option depends on why the money is needed, the current mortgage, the home’s value, the borrower’s income and the lender’s underwriting rules.
HELOC vs. Home Equity Loan
The two products are similar because both use home equity as collateral, but their structures are different.
| Feature | HELOC | Home Equity Loan |
|---|---|---|
| Funding | Revolving credit line | Lump sum |
| Interest rate | Usually variable | Often fixed |
| Borrowing | Draw as needed | Receive upfront |
| Payment | Can change | Usually predictable |
| Best suited to | Flexible or recurring expenses | Known large expense |
| Available credit | Can replenish during draw period | Does not normally replenish |
| Rate risk | Higher because rate can change | Lower with fixed rate |
The CFPB explains that a home-equity loan provides a specific amount while a HELOC allows repeated borrowing from an available credit line.
Current HELOC Rates in September 2026
As of September 16, 2026, Bankrate reported a national average HELOC rate of 7.11%.
Its reported range was approximately 3.99% to 11.60%, although the rate available to an individual borrower can differ substantially.
Bankrate’s national average is based on a specific borrower profile: a $30,000 line, 700 FICO score, 80% combined loan-to-value and a primary single-family residence.
That is important for borrowers seeking $500,000 or $1 million because a large HELOC can receive a different rate and underwriting treatment.
Do not assume that a published national average will be the rate you receive.
Current Home Equity Loan Rates in September 2026
Bankrate reported a national average home-equity-loan rate of 8.15% as of September 16, 2026.
Its reported average rates included:
| Loan Term | Average Rate |
|---|---|
| 5 years | 8.15% |
| 10 years | 8.31% |
| 15 years | 8.26% |
These averages are based on a particular borrower and property profile and should not be interpreted as guaranteed offers.
What Would a $500K Home Equity Loan Payment Look Like?
The payment depends on the interest rate and repayment term.
For illustration only, consider a $500,000 fixed-rate home-equity loan at 8.15%.
A longer repayment period would generally produce a lower monthly payment but more total interest over the life of the loan.
| Loan Amount | Example Rate | Term | Approx. Monthly Principal & Interest |
|---|---|---|---|
| $500,000 | 8.15% | 10 years | ~$6,120 |
| $500,000 | 8.15% | 15 years | ~$4,833 |
| $500,000 | 8.15% | 20 years | ~$4,201 |
| $500,000 | 8.15% | 30 years | ~$3,716 |
These are illustrative calculations only and exclude taxes, insurance, fees and other costs.
The actual rate and payment could be significantly different.
What Would a $1 Million Home Equity Loan Payment Look Like?
At the same hypothetical 8.15% rate:
| Loan Amount | Term | Approx. Monthly Principal & Interest |
|---|---|---|
| $1,000,000 | 10 years | ~$12,240 |
| $1,000,000 | 15 years | ~$9,666 |
| $1,000,000 | 20 years | ~$8,402 |
| $1,000,000 | 30 years | ~$7,432 |
Again, these figures are illustrations rather than actual lender offers.
At this loan size, even a relatively small change in interest rate can have a major impact on the total cost.
What Would a $1.5 Million Home Equity Loan Payment Look Like?
For a $1.5 million loan at the same hypothetical 8.15% rate:
| Loan Amount | Term | Approx. Monthly Principal & Interest |
|---|---|---|
| $1,500,000 | 10 years | ~$18,360 |
| $1,500,000 | 15 years | ~$14,499 |
| $1,500,000 | 20 years | ~$12,603 |
| $1,500,000 | 30 years | ~$11,148 |
These calculations demonstrate why large home-equity loans need careful comparison.
A rate difference of even 0.50% can represent a substantial amount of money when the balance reaches seven figures.
What Credit Score Is Needed for a Large HELOC?
There is no single credit-score requirement across all lenders.
However, larger home-equity requests generally receive more scrutiny.
A lender may examine:
- Credit score
- Payment history
- Existing debt
- Income
- Employment
- Debt-to-income ratio
- Loan-to-value ratio
- Property value
- Existing mortgage
- Cash reserves
A borrower with excellent credit and substantial equity may have access to more options than someone with weaker credit and a high existing mortgage balance.
What Debt-to-Income Ratio Is Needed?
Debt-to-income ratio, or DTI, compares monthly debt obligations with qualifying income.
For example:
Gross monthly income: $20,000
Monthly debt payments: $6,000
DTI: 30%
A lender may use different DTI limits depending on the product, borrower and overall risk profile.
For a $1 million-plus home-equity request, the lender may also evaluate the borrower’s broader financial position rather than relying on a single DTI threshold.
How Much Home Equity Do You Need?
The amount of equity required depends on how much you want to borrow and the lender’s maximum combined loan-to-value ratio.
A simplified formula is:
Potential additional borrowing = Home value × Maximum CLTV − Existing mortgage balance
For example:
Home value: $2,000,000
Maximum CLTV: 80%
Existing mortgage: $400,000
$2,000,000 × 80% = $1,600,000
$1,600,000 − $400,000 = $1,200,000
Under this simplified calculation, the homeowner could theoretically have up to $1.2 million of additional borrowing capacity.
The actual lender limit may be lower.
What Documents Are Needed for a Large Home Equity Loan?
For a substantial loan, expect more documentation than for a small personal loan.
A lender may request:
- Government-issued identification
- Mortgage statement
- Property information
- Proof of income
- Recent pay statements
- Tax returns
- Bank statements
- Investment-account statements
- Employment verification
- Insurance information
- Property appraisal
- Information about other debts
- Documentation concerning the source of assets
Self-employed borrowers may need additional business and income documentation.
How Is Your Home Value Determined?
The lender needs to establish the value of the property because the home serves as collateral.
Depending on the lender and transaction, this may involve:
- Full appraisal
- Automated valuation
- Desktop valuation
- Drive-by appraisal
- Other approved valuation methods
For a $1 million-plus home-equity request, the lender may have more stringent valuation requirements.
A homeowner should not assume that an online estimate of the home’s value will be accepted for a major lending transaction.
HELOC vs. Cash-Out Refinance
A cash-out refinance replaces the existing mortgage with a new, larger mortgage and provides the difference in cash.
A HELOC generally leaves the first mortgage in place and adds a revolving second lien.
Consider this simplified example:
Home value: $2 million
Existing mortgage: $400,000
Desired cash: $500,000
With a HELOC, the borrower could potentially retain the $400,000 first mortgage and add a new home-equity line.
With a cash-out refinance, the borrower could replace the existing mortgage with a larger first mortgage and receive cash from the difference.
The choice can be particularly important when the existing first mortgage has a low interest rate.
Why Homeowners With Low Existing Mortgage Rates May Consider a HELOC
Suppose a homeowner currently has a $500,000 mortgage at a low fixed interest rate.
They want $200,000 for a major renovation.
A cash-out refinance would replace the existing mortgage with a new mortgage.
A HELOC or home-equity loan may allow the homeowner to access additional funds without replacing the existing first mortgage.
That can be an important consideration when comparing financing structures.
However, the second mortgage or HELOC carries its own interest rate and fees.
Can You Use a HELOC for Home Improvements?
Yes, home improvements are one common use of home-equity financing.
Potential projects include:
- Kitchen renovations
- Bathroom renovations
- Room additions
- New roofing
- HVAC replacement
- Structural improvements
- Landscaping
- Energy-efficiency upgrades
A homeowner planning several projects over time may prefer the flexibility of a HELOC because funds can generally be drawn as needed during the draw period.
A homeowner who knows the exact project cost may instead prefer a lump-sum home-equity loan.
Can You Use a HELOC for Debt Consolidation?
Some homeowners use home-equity financing to consolidate higher-interest debts.
For example, someone might consider replacing multiple high-interest debts with a lower-rate secured loan.
However, this changes unsecured debt into debt secured by the home.
That means the borrower should carefully evaluate the risks before proceeding.
A HELOC should not be viewed simply as cheap money.
The CFPB warns that borrowers who cannot repay a HELOC can risk losing their home because the property secures the credit line.
Can You Use Home Equity for Business Funding?
Some homeowners consider home-equity financing to fund a business.
For example:
Home value: $2.5 million
Existing mortgage: $500,000
Requested HELOC: $500,000
The borrower could potentially use the proceeds for business purposes if permitted by the lender.
However, this creates a major distinction between the business and the collateral.
If the business performs poorly and the borrower cannot repay the HELOC, the home remains at risk because it secures the loan.
For large borrowing needs, business loans, commercial financing and other alternatives should also be compared.
Can You Get a HELOC on an Investment Property?
Some lenders offer home-equity financing for investment properties, but requirements can be more restrictive than for a primary residence.
The lender may examine:
- Rental income
- Property value
- Existing mortgage
- Occupancy
- Property type
- Number of properties owned
- Credit profile
- Cash reserves
- Debt-to-income ratio
Not every HELOC lender accepts investment properties.
Therefore, investors should specifically ask whether the property qualifies before submitting an application.
Can You Get a HELOC on a Second Home?
Some lenders offer home-equity products for second homes, but eligibility varies.
Second-home borrowers may face different underwriting requirements from primary-residence borrowers.
Ask the lender specifically about:
- Maximum CLTV
- Maximum loan amount
- Minimum credit score
- Reserve requirements
- Property location
- Occupancy requirements
Large HELOCs and Private Banking
Homeowners seeking $1 million or more may encounter private-bank or specialized portfolio lending.
These programs can be relevant to high-net-worth borrowers who have:
- Significant home equity
- High income
- Large investment portfolios
- Substantial deposits
- Multiple properties
- Complex financial relationships
Private-bank financing can involve individualized underwriting, so borrowers should compare the actual loan terms rather than assuming that private banking automatically means lower rates or better terms.
What Are the Risks of Borrowing $500K–$1.5M Against Your Home?
Large home-equity financing creates significant financial obligations.
Potential risks include:
Variable HELOC rates
Many HELOCs have variable interest rates, meaning the payment can change.
Property risk
Your home serves as collateral.
Increased monthly obligations
A large second mortgage can significantly increase monthly expenses.
Overleveraging
Borrowing too much against the property can reduce your equity cushion.
Property-value declines
If the home’s market value decreases, the homeowner can have less equity available.
Refinancing difficulty
A large second lien can complicate future refinancing or property sales.
The CFPB specifically notes that borrowers who fall behind on a HELOC can risk losing their home.
How to Compare $500K–$1.5M Home Equity Lenders
For large borrowing amounts, compare more than the advertised interest rate.
| Factor | What to Compare |
|---|---|
| Maximum loan | Can the lender actually provide $500K, $1M or $1.5M? |
| CLTV | What maximum combined LTV is allowed? |
| Rate | Fixed or variable? |
| APR | What is the total borrowing cost? |
| Fees | Origination, appraisal and other charges |
| Draw period | How long can funds be accessed? |
| Repayment period | How long must the balance be repaid? |
| Rate ceiling | What is the maximum possible variable rate? |
| Credit requirements | Minimum and preferred credit profile |
| Property type | Primary, second home or investment |
| Reserves | How much liquidity is required? |
| Income | What income documentation is accepted? |
| Existing mortgage | Does the lender allow a second lien? |
| Loan purpose | Are there restrictions on how funds are used? |
For variable-rate HELOCs, borrowers should also understand the maximum possible interest rate. Federal rules require applicable disclosures concerning the maximum rate that can apply to a home-equity plan.
Questions to Ask Before Taking a $500K+ HELOC
Before accepting a large HELOC, ask:
- What is the maximum credit line?
- What is the maximum CLTV?
- What rate would I receive?
- Is the rate fixed or variable?
- What index and margin determine the rate?
- What is the maximum lifetime rate?
- How long is the draw period?
- How long is the repayment period?
- Are there annual fees?
- Are there closing costs?
- Is there an early-termination fee?
- Can I convert part of the balance to a fixed rate?
- Can the property be an investment property?
- What credit score is required?
- How much income must I document?
- Are cash reserves required?
- Is there a minimum initial draw?
- What happens to the payment when the draw period ends?
These questions become increasingly important as the requested credit line gets larger.
When a Home Equity Loan May Make More Sense Than a HELOC
A home-equity loan can make sense when you know exactly how much money you need.
For example, suppose you have a $500,000 renovation project with a fixed budget.
A fixed-rate home-equity loan can provide the full amount upfront and establish a predictable repayment schedule.
Bankrate’s September 2026 data shows average fixed home-equity rates above 8%, although actual offers vary by borrower and lender.
When a HELOC May Make More Sense
A HELOC may be useful when the exact amount needed is uncertain or when funds will be used over time.
For example, consider a homeowner planning:
- $100,000 kitchen renovation
- $75,000 addition
- $50,000 landscaping
- $75,000 structural improvements
Instead of borrowing the entire $300,000 immediately, a HELOC could potentially allow the homeowner to draw funds as expenses arise.
The trade-off is that many HELOCs have variable rates, so the cost can change.
How to Prepare for a $1 Million Home Equity Application
Before applying, calculate:
1. Current property value
Get a realistic estimate of what the home could sell for today.
2. Existing mortgage
Determine your current outstanding balance.
3. Available equity
Subtract the mortgage from the estimated property value.
4. Maximum borrowing
Estimate what the lender’s CLTV limit could allow.
5. Income
Calculate your documented qualifying income.
6. Existing debt
Include mortgages, car loans, credit cards, student loans and other obligations.
7. Cash reserves
Determine how much money you will have remaining after borrowing.
8. Loan purpose
Be prepared to explain how the funds will be used if required.
Example: $1 Million HELOC Qualification Scenario
Imagine a homeowner has:
Property value: $3 million
Existing mortgage: $500,000
Equity: $2.5 million
Requested HELOC: $1 million
If a hypothetical lender allows 80% CLTV:
$3 million × 80% = $2.4 million
Existing mortgage:
$500,000
Potential additional borrowing under the simplified calculation:
$2.4 million − $500,000 = $1.9 million
The requested $1 million would therefore fall below the simplified maximum.
But the borrower would still need to satisfy the lender’s income, credit, property and other underwriting requirements.

Frequently Asked Questions
Can I get a $500,000 HELOC?
Some lenders offer HELOCs with maximum credit lines of $500,000 or more. Bankrate’s September 2026 marketplace includes products with maximum amounts of $700,000 and $750,000, although eligibility varies.
Can I get a $1 million HELOC?
A $1 million HELOC may be available to certain high-equity borrowers, but it is considerably more specialized than a typical HELOC. You may need substantial equity, strong income and credit, and a lender capable of handling large credit lines.
Can I get a $1.5 million HELOC?
Potentially, but the number of lenders offering credit lines at this level is more limited. High-net-worth, private-bank and portfolio lending may become relevant.
What credit score is needed for a $500K HELOC?
There is no universal minimum. Lenders can establish their own credit requirements, and large credit lines may receive more detailed underwriting.
How much equity do I need for a $1 million HELOC?
It depends on the lender’s maximum CLTV and your existing mortgage.
For example, if a lender allows 80% CLTV and your home is worth $2.5 million, the maximum total secured debt under that simplified calculation would be $2 million. Your existing mortgage would then be subtracted to determine potential additional borrowing.
Is a HELOC rate fixed or variable?
Most HELOCs have variable interest rates, although some products or lenders may offer fixed-rate options or fixed-rate conversion features.
Is a home equity loan fixed-rate?
Home-equity loans are commonly structured with fixed rates, although the specific terms depend on the lender.
Can I use a HELOC for a business?
Some homeowners use home-equity financing for business purposes, but the home remains collateral. Borrowers should carefully consider the risk and compare business financing alternatives.
Can I get a home equity loan on an investment property?
Some lenders offer home-equity financing for investment properties, but requirements can be more restrictive than for primary residences.
Does a HELOC affect my first mortgage?
A HELOC generally functions as an additional lien rather than replacing the existing first mortgage. This can allow homeowners to retain an existing mortgage instead of refinancing it.
Bottom Line
A homeowner with substantial property equity may have access to significant borrowing capacity, but a $500,000, $1 million or $1.5 million home-equity loan is not the same as a typical small HELOC.
The key factors are the home’s current value, existing mortgage balance, combined loan-to-value ratio, credit profile, income, debt obligations, reserves and lender-specific maximum loan amounts.
As of September 2026, the national average HELOC rate reported by Bankrate was 7.11%, while the average home-equity-loan rate was 8.15%. Actual rates for large loans can differ substantially from these national averages.
For homeowners with large amounts of equity, the most important step is to compare the entire financing structure, not just the advertised interest rate.
A HELOC can provide flexible access to funds, while a home-equity loan can provide a predictable lump sum. A cash-out refinance, private-bank loan or other financing option may also be relevant depending on the homeowner’s existing mortgage and financial objectives.
Most importantly, because the home secures the borrowing, a large home-equity loan should be treated as a major financial obligation rather than simply another source of cash.
