A guide to home equity

Leveraging home equity can be a great way to help you achieve your financial goals, especially when it comes to property investment.

Whether you’ve been playing the real estate game for years or you’re new to the party, this guide will help you calculate your home equity and how much you might be able to free up towards purchasing an investment property.

What is equity?

Let's start by understanding what equity is. Equity is the difference between the current market value of your property and the outstanding balance on your mortgage.

With every mortgage repayment you make, the portion of your property that you own will increase. Additionally, although this isn’t guaranteed, the value of your home should also go up over time. Between the two, the equity you have in your home will grow, making it a valuable asset you can utilise for any number of large financial undertakings, such as a holidayrenovations, or, you guessed it, investment property.

What is useable equity?

The difference between total equity and useable equity is the portion that lenders are willing to lend against. The useable amount of equity depends on things such as the loan-to-value ratio (LVR) and the policies of the lender in question.

Not all the equity in your property may be available to you. Understanding how much useable equity you have is a vital first step when considering using equity to make investment plans.

In general, your useable equity is around 80% of your total equity. Lenders tend to favour this sort of figure to keep you from having to pay Lenders Mortgage Insurance (LMI).

What is total equity?

Total equity is the value of the portion of your property that you own. In other words, it’s your useable and non-useable equity amounts combined. This is the figure lenders use to assess your overall financial position and how much you’re able to borrow for the purpose of buying an investment property.

How much could you borrow for an investment property?

Imagine you live in a property with a market value of $500,000. Most lenders won’t allow to owe more than 80% of that figure, which is $400,000. So, if you still owe $300,000 on your home loan, then the maximum you would be able to put towards an investment property would be $100,000.

When researching equity, you may have come across the ‘rule of four’. It is a principle to prevent you from overextending yourself financially. In a nutshell, the rule is to avoid borrowing more than four times the useable equity in your home.

This helps you maintain a reasonable level of debt and avoid problems associated with owing more than you can afford to repay. In theory at least, sticking to the ‘rule of four’ should safeguard you against market volatility and other unexpected increases to your outgoings.

Final thoughts

When calculating your equity and your capacity to borrow, banks and financial institutions will consider factors such as your income, credit history, existing debt and the potential rental income you can make from any investment properties you purchase.

Understanding the concept of equity, and how much of it is available to you, can give you great insight into what you can afford to do – be that purchasing an investment property or using the money for something else.

Important Information

Rates current as at 13 November 2024 and subject to change.

Great Southern Bank, a business name of Credit Union Australia Ltd ABN 44 087 650 959, AFSL and Australian Credit Licence 238317. Lending criteria, limits, conditions and fees apply. Applications are subject to credit approval.

This is general information and does not take into account your objectives, financial situation or needs. Consider the appropriateness of the information, including the Terms and Conditions (T&Cs)  booklet, before acting on it. The Financial Claims Scheme may apply to this product; refer to the T&Cs for more information.

^Comparison rate accurate for $150,000 secured loan over 25 years. WARNING: This comparison rate is true only for the examples given and may not include all fees and charges. Different terms, fees or other loan amounts might result in a different comparison rate.

1 Discounts off the Basic Variable Reference Rate are available to (a) new home loans with a minimum application amount of $100,000; or (b) switching or restructuring of the home loan you already have with us when it includes new borrowing of at least $10,000; and the application is unconditionally approved on or after 13 November 2024. Published interest rates are inclusive of any discounts off the respective Reference Rates. Interest rates and discounts vary based on the loan purpose (owner occupier or investor), repayment type (principal and interest, interest only, construction) and Loan to Value Ratio (LVR). Maximum LVR applies and includes Lenders' Mortgage Insurance and Great Southern Bank loan setup fees where applicable.

2 Great Southern Bank may withdraw or amend this offer at any time without notice. A change in your loan purpose, your repayment type or your loan product will permanently end your entitlement to the discount.

3 LVR means ‘Loan to Value Ratio’. It is the amount of your loan divided by the valuation of your property, calculated as a percentage. For example, if you apply for a loan of $400,000, which will be secured by a property valued at $500,000, your LVR is 80%. We calculate your LVR at the time we approve your loan and your discount won’t change because of changes to the LVR during the life of your loan.

4 A $200 minimum withdrawal amount applies for redraws conducted in-branch.

5 For Interest Only loans, a maximum interest only period of 36 months applies for owner occupier loans and 60 months for investment loans. For Fixed Rate loans, the interest only period must align with the fixed rate period. On expiry of the Fixed Rate interest only period, loans will revert to the Basic Variable Principal and Interest Owner Occupier or Investor Reference Rate (as applicable) which applies at the time of expiry. On expiry of the Basic Variable interest only period, loans will revert to the Basic Variable Principal and Interest Owner Occupier or Investor Reference Rate (as applicable) which applies at the time of expiry, less any discount set out in the loan contract. On expiry of the Offset Variable interest only period, loans will revert to the Offset Variable Principal and Interest Owner Occupier or Investor Reference Rate (as applicable) which applies at the time of expiry, less any discount set out in the loan contract. Comparison rate for Interest Only loan is based on interest only payments for the fixed term and principal & interest payments for the balance of the term.

Applying for pre-approval allows you to know the maximum amount you can borrow while you look for a property.

Pre-approval means that a lender has agreed to lend you an amount of money in-principle, but the loan hasn't been proceeded to full or final approval.

While pre-approval is not a fully approved loan it can help you narrow your search, negotiate, and make an offer with certainty and confidence.
