How Does a Home Equity Line of Credit Work?

A Home Equity Line of Credit (HELOC) is a type of loan that allows homeowners to borrow against the equity they have in their homes.

The borrower is given a credit limit, and they can borrow as much or as little as they need up to that limit during the draw period, typically 5-10 years.

During the repayment period, which is usually 10-20 years, the borrower pays back what they have borrowed plus interest.

The interest rate on a HELOC is usually variable and is tied to the prime rate. The more equity a homeowner has in their home, the more they may be able to borrow.

Types of HELOC

There are two main types of HELOCs: variable-rate and fixed-rate.


  • Variable-Rate HELOC: Has an interest rate that can change over time.

  • Fixed-Rate HELOC: Has an interest rate that stays the same for the life of the loan.

Loan Terms

HELOCs typically have a draw period, during which you can borrow money from the line of credit, and a repayment period, during which you must pay back what you have borrowed.

Interest Rates

The interest rate on a HELOC is usually variable and is tied to the prime rate. This means that as the prime rate changes, so does the interest rate on your HELOC.

Credit Limit

The credit limit on a HELOC is based on the amount of equity you have in your home and your creditworthiness. The lender will typically allow you to borrow up to a certain percentage of your home's value, minus any outstanding mortgage balance.


Draw Period and Repayment Period

During the draw period, you can borrow money from your HELOC as needed, up to your credit limit. You only pay interest on the amount you borrow, and you can repay the borrowed amount at any time.

During the repayment period, you must pay back what you have borrowed, plus interest. Your monthly payment will depend on the amount you have borrowed and the interest rate on your HELOC.

Eligibility Criteria for a HELOC

Several factors can affect your eligibility for a HELOC, including your credit score, debt-to-income ratio, loan-to-value ratio, and other requirements set by the lender.

Eligibility for a Home Equity Line of Credit

Credit Score Requirements

To qualify for a HELOC, you will typically need a credit score of at least 680. However, a higher credit score will usually result in a lower interest rate and a higher credit limit.

Debt-To-Income Ratio

Your debt-to-income ratio is a measure of how much debt you have compared to your income. Lenders typically prefer borrowers with a debt-to-income ratio of 43% or lower.

Loan-To-Value Ratio

The Loan-To-Value Ratio (LTV) is a measure of how much of your home's value is currently mortgaged. Lenders typically require an LTV of 85% or less to qualify for a HELOC.

Other Requirements

Lenders may have other requirements, such as a minimum income or a certain length of time in your current job or residence. You must also have equity in your home.

Applying for a HELOC

The process for applying for a Home Equity Line of Credit typically involves several steps.

Preparing the Necessary Documents

To apply for a HELOC, you will need to provide documentation such as your mortgage statement, proof of income, and proof of insurance.

Choosing the Right Lender

When choosing a lender, it's important to compare interest rates, fees, and credit limit requirements.

The Application Process

The application process typically involves submitting an application and supporting documentation, such as pay stubs and tax returns. The lender will also order an appraisal of your home to determine its value.

Approval and Disbursement

If you are approved for a HELOC, the lender will disburse the funds to you either in a lump sum or in increments over the draw period. You can then use the funds as needed.

Repaying a HELOC

Involves making minimum payments during the repayment period, typically 10-20 years, that include interest and a portion of the principal.

Minimum Payment Requirements

During the repayment period, you will need to make minimum payments on your HELOC. The minimum payment is typically calculated based on the interest due and a small portion of the principal.

Interest-Only Payment Option

Some lenders offer an interest-only payment option during the draw period. This means that you only pay interest on the amount you borrow and do not have to repay any principal until the repayment period begins.

Principal and Interest Payment Option

The principal and interest payment option requires you to pay both the interest due and a portion of the principal during the draw period.

Paying off the HELOC

To pay off your HELOC, you can make larger payments than the minimum required or pay off the entire balance in a lump sum.

Risks Associated with a HELOC

Home Equity Lines of Credit can be a convenient way to access funds, but it's important to understand the potential risks associated with them before you decide to use this type of financing. Some of the potential risks are:


  • Variable Interest Rates: The interest rate on a HELOC can change over time, which can lead to higher monthly payments.


  • Changing Credit Limits: The lender may adjust your credit limit during the draw period, which could limit your ability to borrow money.



  • Risk of Foreclosure: If you are unable to make payments on your HELOC, the lender may foreclose on your home.

Final Thoughts

A HELOC can be a useful tool for homeowners looking to access equity in their homes. It allows homeowners to borrow against the equity they have built up in their property, and the loan is secured by their home's equity.

However, it's important to understand the risks and benefits of this type of borrowing and to use a HELOC responsibly.

By following the eligibility criteria, choosing the right lender, and making timely payments, you can make the most of your HELOC while minimizing the risks.
