What is home equity?

Home equity is the amount of the property you own once any mortgage debts are subtracted. And you can use this equity in several ways.

How much equity do I have in my home?

Equity is the value of your property minus any debts. It's the amount of the property you own and is expressed as a dollar value. Here's a simple example:

  • Your property is valued at $1,000,000.
  • You have $700,000 remaining on your home loan.
  • The property value minus debt = $300,000 in equity

Your home equity in this scenario is $300,000. Now, equity calculations are always hypothetical to some degree. The value of your property changes over time and you can't really know what it's worth until you sell it. And these quick calculations don't consider things like selling costs (real estate agent commissions, conveyancing fees etc).

Here's a simple visual explanation of the concept of home equity.
Graphic that explains how equity works.

Over time, your equity should grow as you pay off your debt. The other factor affecting your home equity is the property's value. In a rising market, your equity increases by itself as the value of the property grows.

Property owners can use their home equity through line of credit loans or other loan products. This allows you to borrow against the equity to fund investment property purchases, renovations, retirement costs and more.

How do I calculate my home equity?

The calculation, as explained above, is simply the property value minus any debt on the home. You can use this simple calculator to estimate your equity. Just enter the following information:

  1. An estimate of what your property is currently worth.
  2. How much of your home loan is left to repay.

Useable equity is the amount of equity a lender will let you borrow. This is at most 80% of your total equity. The 20% buffer is to reduce the lender's risk.

When estimating your equity, it is important to consider the current property value rather than the price you paid for it. If you bought a home 5 years ago for $650,000, in a rising property market, it could now be worth $700,000.

To get an accurate picture of your remaining debt, check your most recent home loan statement or log onto your lender's banking platform and check your loan account.

How can I use the equity in my home?

There are several finance options property owners can use to unlock the equity in their homes, ranging from line of credit loans to home loan top-ups and, for older Australians, reverse mortgages.

  • Line of credit loan. A line of credit loan allows home owners to borrow money against the equity in their property. The lender approves a certain amount of money based on your equity and charges you interest based only on the money you actually spend. It's a flexible way of using some of your home equity. But keep in mind that interest rates on these loans are higher than regular mortgages. The more you spend, the less equity you will have.
  • Refinance. If you're currently paying off a mortgage, it's possible to switch to a new home loan with a new lender. This is called refinancing your home loan. You can do this to switch to a cheaper home loan with a lower interest rate. But when you switch, you can also use your equity to borrow slightly more with the new home loan.
  • Home loan top-up. Instead of refinancing, you can stick with your existing loan and lender but apply for a home loan top-up. This means keeping the current loan but extending your borrowing limit slightly further.
  • Reverse mortgage. Australian home owners who are aged 60 or older can borrow some of their equity using a reverse mortgage. Interest is charged on what you borrow, and you repay the debt when you sell the property or die. This option can be used to fund your retirement costs, supplement your income or for anything else you need.

What can I use home equity for?

Equity is your wealth. In theory, you can spend it on whatever you want. But sometimes a lender may restrict what you can spend the money on, depending on the type of loan you get.

You can use your home equity for the following:

  • Renovations. Big home renovations are expensive but are a great way to improve and add value to your home. You can use your equity to effectively build more equity.
  • Financing major purchases. You can pay for a holiday or a car through your equity.
  • Investing in property. With enough equity, you could cover the deposit on a second property and then rent it out.

Are there any risks that come with using your equity?

Borrowing your equity reduces how much of your home you own. If you borrow too much, you risk going backwards on your home loan repayments.

Lenders limit how much equity you can access, which gives you some protection. But any borrower looking to cash out some of their equity should know the following:

  • Borrowing your equity adds to your debt. You will have to repay the equity, plus interest, along with your normal mortgage repayments.
  • Interest rates on line of credit loans are higher than ordinary home loans. This means even if you borrow a small amount of equity, the interest charges might be bigger than you think.
  • If you don't have much equity and the property market is in a downward cycle (prices are falling), you might have less equity available than you think. And borrowing some of it risks tipping you into negative equity.

How can I increase the equity in my home?

Home equity increases in several ways. Growth can be passive (if your property value grows over time in a rising market), but you may be able to add value to your property through renovation.

  • Repayments. As you pay off your home loan, you are adding to your equity. If you started a home loan with a 20% deposit, you'd have a loan to value ratio of 80%. After 5 years of diligently repaying your loan, you could be at 70% LVR and 30% equity. Keep in mind this only works if you have been making principal and interest loan repayments. You can build your equity faster by making extra repayments.
  • Capital growth. Over time, property prices in Australia tend to grow. This is called capital growth. According to CoreLogic's Home Value Index, the median Sydney property value in September 2016 was $785,000. In September 2020, the Sydney median stood at $859,943. That's $74,943 in equity a median property would have gained over those 4 years. Of course, there are exceptions, and prices can fall over time too, so passive equity growth through capital growth is never guaranteed.
  • Renovations. Property owners can increase the value of their properties through renovation. Adding an extra room to a house, redoing a kitchen or bathroom or even just a fresh coat of paint can make your property more appealing to buyers, increasing its value.
