If you own a home and have been paying your mortgage for a few years, you may be sitting on a significant financial resource without even realising it — your home equity. A Home Equity Line of Credit (HELOC) is one of the most flexible ways to access that equity. In this guide, we explain exactly what a HELOC is, how it works, what it costs, and how to decide if it is right for your situation.

What is a HELOC?

A HELOC is a revolving line of credit secured against the equity in your home. Think of it like a credit card backed by your house — you are approved for a maximum credit limit, and you can draw from that limit whenever you need funds, repay it, and draw again during a set period.

Your home equity is the difference between what your home is currently worth and what you still owe on your mortgage. For example, if your home is worth $400,000 and you owe $200,000 on your mortgage, you have $200,000 in equity. Lenders typically allow you to borrow up to 80–90% of your home's value minus your existing mortgage balance.

Quick Example

Home value: $400,000 | Mortgage balance: $200,000 | Lender max LTV: 85%
Maximum HELOC: ($400,000 × 85%) − $200,000 = $140,000

How does a HELOC work?

A HELOC operates in two distinct phases: the draw period and the repayment period. Understanding both is essential before you apply.

During the draw period (typically 10 years), you can borrow from your credit line as needed. You might access funds via a debit card linked to the account, by writing a check, or through an online transfer. You only pay interest on the amount you actually borrow — not your full credit limit.

Once the draw period ends, you enter the repayment period (typically 10–20 years), during which you can no longer draw funds and must repay both principal and interest on the outstanding balance.

Many first-time HELOC borrowers are caught off guard by the significant payment increase when the repayment period begins. Always plan your budget around the fully amortised repayment payment, not just the draw-period interest payment.

HELOC interest rates explained

Most HELOCs carry a variable interest rate tied to the Prime Rate (which moves with Federal Reserve policy). Your lender adds a margin on top of the Prime Rate to arrive at your rate. For example: Prime Rate (8.50%) + Margin (0.50%) = Your Rate (9.00%).

Because HELOC rates are variable, your monthly payment can go up or down over time. Some lenders offer a fixed-rate conversion option that lets you lock in a rate on all or part of your balance — worth asking about if you prefer payment predictability.

HELOC vs home equity loan — what is the difference?

A home equity loan gives you a lump sum of money upfront at a fixed interest rate, with fixed monthly payments over a set term. A HELOC gives you a revolving credit line with a variable rate. The right choice depends on how you plan to use the funds.

Frequently asked questions

Can I get a HELOC on a rental or investment property?

Some lenders offer HELOCs on investment properties, but requirements are stricter and rates are typically higher than for primary residences.

How long does HELOC approval take?

The process typically takes two to six weeks, including application, appraisal, underwriting, and closing.

Can I pay off a HELOC early?

Yes, though some lenders charge an early closure fee (typically if you close the line within two to three years). Check your loan agreement before prepaying.

What happens to my HELOC if I sell my home?

When you sell, the HELOC balance is paid off at closing from the sale proceeds, just like your primary mortgage.
