The True Cost of Borrowing Money for a Home

Introduction The dream of owning a home is a significant milestone for many South Australians. However, understanding the true cost of borrowing money for a home is crucial to making an informed decision. This comprehensive guide delves into the various costs associated with home loans, helping potential buyers in South Australia navigate the financial complexities of homeownership.

Understanding Mortgage Basics

Principal and Interest

The principal is the amount of money borrowed to purchase the home, while interest is the cost of borrowing that money, typically expressed as an annual percentage rate (APR). For instance, if you borrow $500,000 with an interest rate of 3%, your annual interest cost would be $15,000, adding significantly to your repayment amounts over the life of the loan.

Fixed vs. Variable Rates

  • Fixed-rate mortgages have a consistent interest rate throughout the loan term, offering stability in monthly repayments. This can be beneficial in times of low interest rates but may be less flexible if rates drop further.
  • Variable-rate mortgages have interest rates that can fluctuate based on market conditions, potentially offering lower rates but also carrying the risk of higher payments if rates rise.

Additional Costs of Borrowing

Lender’s Mortgage Insurance (LMI)

LMI is typically required if your deposit is less than 20% of the property’s value. This insurance protects the lender in case you default on the loan. For a $500,000 loan with a 10% deposit, LMI could cost approximately $8,000, depending on the lender and the specifics of the loan.

Stamp Duty

Stamp duty is a government tax applied to property purchases, varying depending on the property value and location. In South Australia, stamp duty on a $500,000 home can be around $21,330. First home buyers may be eligible for concessions, reducing this cost significantly.

Legal and Conveyancing Fees

These fees cover the legal aspects of buying a home, including title searches, contract reviews, and settlement. They typically range from $1,000 to $2,500.

Hidden Costs and Fees

Application and Establishment Fees

These are fees charged by lenders to process and set up the loan, ranging from a few hundred to several thousand dollars. It’s essential to compare these fees across different lenders as they can significantly impact the overall cost of borrowing.

Ongoing Fees

Some lenders charge monthly or annual fees to manage the loan account. These can include account-keeping fees and loan service fees, adding up over the life of the loan.

Exit Fees and Break Costs

Exit fees apply for paying off the loan early or switching to another lender. Break costs, which can be significant for fixed-rate loans, compensate the lender for lost interest income due to early repayment. It’s crucial to understand these fees before committing to a loan.

Impact of Interest Rates on Borrowing Costs

How Interest Rates Affect Monthly Payments

Higher interest rates increase monthly payments and the overall cost of the loan. For example, a 1% increase in interest on a $500,000 loan can add approximately $300 to your monthly repayments.

Comparing Different Interest Rate Scenarios

Using mortgage calculators, you can compare how different interest rates impact total repayments. For instance, a 3% interest rate on a $500,000 loan over 30 years results in monthly payments of around $2,108, while a 4% rate increases payments to $2,387.

Strategies to Minimize Borrowing Costs

Increasing Your Deposit

Saving for a larger deposit reduces the loan amount and LMI costs, resulting in lower monthly payments and interest savings over the loan’s life. A 20% deposit on a $500,000 home eliminates LMI and reduces your loan to $400,000.

Shopping Around for the Best Rates

Compare different lenders and loan products, considering both interest rates and associated fees. Websites like Canstar and RateCity offer tools to compare loan options, helping you find the best deal.

Fixed vs. Variable Rates: Choosing the Right Option

Consider the pros and cons of fixed and variable rates based on your financial situation and market conditions. Fixed rates offer stability, while variable rates can provide savings if interest rates fall.

Government Assistance and Grants

First Home Owner Grant (FHOG)

The FHOG offers financial assistance to first-time buyers. In South Australia, eligible buyers can receive up to $15,000 for new homes, helping reduce the overall cost of borrowing.

Stamp Duty Concessions

Eligible buyers can apply for stamp duty concessions, significantly reducing this cost. It’s important to check the latest eligibility criteria and application processes.


Understanding the true cost of borrowing money for a home involves more than just the interest rate. Potential homebuyers in South Australia need to consider various additional costs and fees associated with home loans. By being aware of these costs and utilising strategies to minimise them, buyers can make more informed decisions and potentially save thousands of dollars over the life of their mortgage.
