Fixed Rate Home Loans: Features, Benefits & Drawbacks

Fixed rate home loans lock your interest rate for a set period, typically one to five years. This gives you predictable monthly repayments but limits your ability to make extra payments or switch loan types without penalties.

With some lenders currently offering fixed rates below their variable options, understanding how fixed rate loans work matters before you commit to a long-term rate lock.

How Fixed Rate Home Loans Work

A fixed rate loan maintains the same interest rate for an agreed period. Your repayments stay the same each month, regardless of what happens to interest rates in the broader market.

Most lenders offer fixed terms from one to five years. Three and five-year terms are most popular because they balance payment certainty with flexibility.

Some lenders extend fixed terms to seven or ten years, though these longer periods are less common and may carry higher rates.

At the end of your fixed period, your loan typically reverts to the lender's standard variable rate. This revert rate may not be the lender's most competitive variable offering.

Fixed Rate Loan Restrictions

Fixed rate loans come with several limitations that variable loans do not have:

Extra repayment limits: Most lenders cap additional payments during the fixed period. Common limits range from $10,000 to $30,000 per year above your minimum repayment.
Break costs: If you pay out the loan early, sell the property, or switch to a variable rate during the fixed term, you may face break costs. These fees compensate the lender for their funding costs and can reach thousands of dollars.
Limited loan features: Fixed rate loans typically exclude offset accounts, redraw facilities, and other flexible features available with variable loans.
Refinancing restrictions: Switching lenders during a fixed period usually triggers break costs, limiting your ability to take advantage of better deals elsewhere.

Rate Lock Options and Pre-approval

When you apply for a fixed rate loan, you can pay a rate lock fee to secure your interest rate for 60 to 90 days. This protects you from rate rises between application and settlement.

Rate lock timing varies by lender. Some apply the lock from application, others from formal approval. Understanding your lender's policy prevents surprises if rates move during your application process.

Fixed rate loans can be pre-approved, allowing you to secure financing before finding a property. Pre-approval shows sellers you are a serious buyer and helps you understand your borrowing capacity with certainty about your future repayments.

Split Loan Arrangements

Split loans divide your borrowing between fixed and variable portions. Common splits include 50/50, 70/30, or any ratio that suits your needs.

A split loan lets you lock payment certainty on part of your debt while maintaining flexibility on the remainder. The variable portion typically allows unlimited extra repayments and access to features like offset accounts.

For example, on a $600,000 loan split 60/40 fixed to variable, you would have $360,000 at a fixed rate and $240,000 at a variable rate. If the fixed portion is at 5.5% and the variable at 6.0%, your blended rate would be approximately 5.7%.

When Fixed Rates Suit Borrowers

Fixed rates work well for borrowers who prioritise payment certainty over flexibility. They suit households with tight budgets who need predictable housing costs for financial planning.

First home buyers often prefer fixed rates because they provide stability during the adjustment period of homeownership. Investment property buyers may also choose fixed rates if they want predictable rental yield calculations.

Fixed rates are less suitable for borrowers who plan to make large extra repayments or those who may need to sell within the fixed period.

Comparing Fixed Rate Options

Fixed rates vary significantly between lenders. Banks, credit unions, and non-bank lenders all structure their fixed rate products differently.

Factors to compare include:

Interest rates across different terms
Extra repayment allowances
Break cost calculations
Available loan features during the fixed period
Revert rates after the fixed term expires

An experienced broker can compare fixed rate options across multiple lenders to find terms that match your circumstances.

Understanding Break Costs

Break costs apply when you exit a fixed rate loan early. Lenders calculate these fees based on the difference between your fixed rate and current wholesale funding costs.

If interest rates have fallen since you fixed your loan, break costs can be substantial. If rates have risen, break costs may be minimal or non-existent.

Always request a break cost estimate from your lender before making decisions about early repayment, refinancing, or property sales during a fixed period.

Planning for Rate Reversion

Your loan agreement specifies what happens when your fixed period ends. Most loans revert to the lender's standard variable rate, which is typically higher than their best variable rates.

Before your fixed term expires, review your options. You may be able to:

Fix again for another term
Switch to a competitive variable rate with your current lender
Refinance to a different lender for better ongoing rates

Planning for reversion six months before your fixed term ends gives you adequate time to compare options and make an informed decision without time pressure.
