      Quick insights

      • A home equity line of credit (HELOC) acts much like a credit card, but the limit is based on your equity, and your home is the guarantee.
      • You can use HELOC funds for various expenses, with common choices being home upgrades, paying off other debts or covering bills.
      • The HELOC setup lets you borrow money over a period of years (draw period) before a separate repayment period begins.

      As you make mortgage payments and your home’s value increases, you build equity. This can be accessed through a home equity line of credit (HELOC), a revolving line of credit secured by your home. You can withdraw money as needed for several years up to an approved limit. Whether you’re planning for a home improvement project, consolidating debt or preparing for education expenses, a HELOC can offer a flexible way to access available equity.

      How does a HELOC work?

      A HELOC functions like a credit card but is secured by the equity in your home. When you open a HELOC, you’re given a credit limit based on the value of your home minus any existing mortgage balance. You can then draw from this line of credit up to your limit as needed.

      • Draw period: This is the initial phase, typically lasting 3-10 years, during which you can borrow from your HELOC and make payments. Loan providers may allow or require interest-only payments on the amount you draw. Some loan providers may offer an option to pay down the principal as well.
      • Repayment period: After the draw period ends, the repayment period can last 10-20 years. During this time, you can no longer draw from your HELOC and must start repaying both the principal and interest. Monthly payments are often higher during this phase because of this.
      • Example: You open a $30,000 HELOC. During the draw period, you use $15,000 for the renovation. You can still borrow up to your $30,000 limit during the draw period. In this example, this would be an additional $15,000 unless you paid down your principal and freed up more of your initial limit.

      How much can you borrow with a HELOC?

      Many lenders determine your maximum HELOC amount based on a percentage of your home’s value and your current mortgage balance. Your loan-to-value ratio (LTV) is important but only accounts for your primary mortgage balance. When you want to access home equity, many use the combined loan-to-value (CLTV) ratio.

      Along with other factors in your financial profile, CLTV is used to calculate the HELOC limit that a lender offers, and 80% is a common limit.

      Here’s a basic formula:

      (Home value x maximum CLTV) - Current mortgage balance = Maximum HELOC

      Example: You owe $180,000 on a home worth $300,000:

      ($300,000 x 0.80) - $180,000 = $60,000

      The maximum HELOC you may be offered would be $60,000.

      These figures are provided solely for educational purposes. Actual borrowing limits vary by lender and may depend on a range of factors, such as your credit profile, income and available home equity. Consult with a lender for specific terms.

      HELOC requirements and qualifications

      When applying for a HELOC, mortgage providers assess several factors to determine your eligibility. Here’s a closer look at several general requirements:

      • Credit score and credit history: Lenders consider both your credit score and credit history when reviewing a HELOC application. A strong credit profile may improve your chances of approval and terms.
      • Loan-to-value ratio (LTV): The LTV ratio is your mortgage balance compared to the appraised value of your home expressed as a percentage. For example, if your home is worth $300,000 and you owe $200,000 on your mortgage, your LTV ratio is about 67%. For home equity products, lenders may prefer an LTV ratio of 80% or lower.
      • Income and employment: Lenders review your income and employment history to assess your ability to repay a HELOC. You’re usually asked to provide documentation as proof, such as paystubs, tax returns or other records that verify stable and consistent income. This is true whether you work for an employer or are self-employed.
      • Debt-to-income ratio (DTI): Your DTI ratio compares your monthly debt obligations to your gross monthly income. A lower DTI ratio may suggest better financial health and could improve your eligibility for a HELOC.
      • Home appraisal: The home appraisal or other valuation method is normally required to determine the current market value of your home. This helps establish your available equity and borrowing limit.
      • Home equity: Mortgage lenders have different equity requirements when offering HELOCs. Besides providing a maximum borrowing amount, your available equity usually affects how much you qualify to borrow.

      Pros of a HELOC

      • Flexibility: During your draw period, you can borrow as needed up to your credit limit, which can be useful for ongoing expenses or renovation projects.
      • Interest rates: Usually, HELOCs have lower interest rates compared to credit cards and personal loans because they are secured by your home.
      • Interest-only payments: During the draw period, you often only pay interest on the amount borrowed, which could keep payments lower.
      • Tax benefits: Interest on a HELOC may be tax-deductible if used for home improvements. Please consult with a tax advisor for specifics.

      Cons of a HELOC

      • Potential for over-borrowing: The revolving nature of a HELOC might tempt you to borrow more than necessary, leading to higher debt and financial strain.
      • Home as collateral: Failure to repay a HELOC could result in foreclosure. Ensure you’re confident in your ability to manage repayment to help avoid this risk.
      • Fees and costs: There may be fees for initial setup, annual maintenance or early repayment. Understanding these costs can help you know the true expense of a HELOC.

      Is it a good idea to get a HELOC?

      The answer depends mostly on your goals, available equity and ability to make payments. The general advantage is the flexibility for phased expenses. The inherent risks are the variable monthly payments and the fact that your home secures the debt. If you require a flexible source of money and can manage variable rates, a HELOC is a powerful financial tool. If you need payment predictability, market rates may not provide that with a HELOC when it comes time to repay what you borrow.

      How to apply for a HELOC

      When applying for a HELOC, you may want to consider a few factors such as your financial stability, equity in your home and long-term goals. Before you begin, make sure you have a stable income and strong credit history. You will also need sufficient home equity to qualify for a HELOC. An LTV ratio of 80% or lower is typically preferred by lenders. Evaluate if taking on additional debt aligns with your financial goals.

      Here is a guide to help you navigate the process of applying for a HELOC:

      • Assess your needs: Determine how much credit you need and how you’ll use the funds. This will help you select the right HELOC terms.
      • Check your credit: Review your credit report and score. Try to aim for a score of 620 or higher because this can improve your chances of approval and secure better terms.
      • Calculate your home equity: Find out the current value of your home and subtract any existing mortgage balance to estimate your available equity. Your existing mortgage balance could also include any open HELOCs or home equity loans. The estimate may give you an idea of your borrowing limit; however, a home lending professional may be able to provide a clearer estimate.
      • Research lenders: Compare HELOC offers from different mortgage providers, including banks, credit unions and online lenders. Look at interest rates, fees, terms and customer reviews.
      • Complete the application: Apply with a lender of your choice. This can typically be done online, over the phone or in person.

      In summary

      A HELOC can be a powerful financial tool for homeowners seeking a flexible source of credit. HELOCs can be used to fund home improvements, consolidate debt or handle unexpected expenses. If you’re considering one, carefully assess how borrowing and repaying fit into your financial situation. With careful planning, you can effectively leverage your home’s equity to achieve your financial goals.

      FAQs about HELOCs

      Common mistakes to avoid when getting a HELOC

      Common mistakes include borrowing more than needed, using funds for nonessential expenses and overlooking the impact of variable interest rates on repayment. Reviewing the costs and terms, and sticking to a solid repayment strategy, may help you use a HELOC responsibly.

      What is the difference between a HELOC and a home equity loan?

      HELOC vs. Home equity loan: A HELOC is a revolving line of credit with variable interest rates and flexible borrowing and repayment options. A home equity loan provides a lump sum with fixed interest rates and fixed monthly payments. HELOCs can be ideal for ongoing expenses, while home equity loans suit one-time large expenses. For example, if you’re approved for $50,000, a HELOC allows you to borrow only what you need, while a home equity loan provides the full $50,000 upfront.

      Can you pay early?

      In many cases, you can pay off a HELOC early, which may reduce the amount of interest you pay over time. However, some lenders may charge an early payoff fee or prepayment penalty charge to recoup the bank’s origination costs. It’s important to review your loan agreement.
