Fixed Rate Loans Give You Certainty, But You Pay for That Security
A fixed rate locks your repayment at a set amount for a chosen period, typically between one and five years. That certainty comes with conditions that can restrict how you manage your loan during the fixed period, and exit costs if you need to break the contract early.
For first home buyers on the Central Coast, where household budgets often stretch to meet entry prices in suburbs like Terrigal, Wamberal, and Avoca Beach, knowing what you gain and what you give up under a fixed rate makes a material difference to your financial position over the life of the loan. The choice is not whether one option is universally superior, but which structure aligns with how you plan to use your property and manage repayments in the first few years of ownership.
Why First Home Buyers Consider Fixed Rates
Fixed rates appeal when you want to protect your repayments from rate rises during the period when your budget has the least margin for error. In the first few years of ownership, many buyers face settlement costs, furniture purchases, and the ongoing cost of maintaining a property while adjusting to mortgage-level repayments.
Consider a buyer securing a property in the Wyong or Toukley area. With a 10% deposit under the First Home Guarantee, their repayments start immediately at the variable or fixed rate offered at settlement. If rates rise by 0.50% within the first year, a variable loan increases monthly repayments by several hundred dollars depending on loan size. A fixed rate holds that repayment steady, giving the buyer time to build income or adjust their budget without immediate pressure.
That scenario works well if rates rise or hold. If rates fall during your fixed period, you continue paying the higher rate while variable borrowers benefit from the reduction. The contract runs both ways.
What You Cannot Do During a Fixed Rate Period
Most fixed rate loans do not offer an offset account. That feature, which reduces interest by offsetting your savings balance against your loan, is typically reserved for variable loans or comes with a higher fixed rate that erodes much of the benefit.
You are usually restricted to a maximum of $10,000 to $30,000 in extra repayments per year without triggering break costs. Some lenders allow no additional repayments at all during the fixed term. For buyers who expect a tax refund, bonus, or family contribution in the first year or two, this restriction directly affects how quickly you can reduce your principal.
You also cannot refinance to another lender during the fixed period without paying break costs, which are calculated based on the difference between your fixed rate and the rate the lender can now earn by re-lending that money. If rates have dropped significantly since you fixed, break costs can reach tens of thousands of dollars. If rates have risen, break costs may be zero, but you would not want to refinance in that environment anyway.
The Split Rate Structure That Gives You Both Options
A split loan divides your borrowing into two portions: one fixed, one variable. You might fix 50% or 60% of the loan to lock in a portion of your repayment, while leaving the remainder on a variable rate with an offset account and unlimited extra repayment capacity.
In our experience, buyers who plan to make irregular lump sum repayments, whether from bonuses, rental income if they later move out, or family gifts, benefit from keeping a portion of the loan variable. The fixed portion stabilises the minimum repayment, while the variable portion absorbs any extra cash without restriction.
The ratio you choose depends on how much repayment certainty you want versus how much flexibility you expect to need. A 70/30 split weighted toward fixed gives more protection. A 40/60 split weighted toward variable gives more room to pay down debt when cash flow allows. There is no standard formula because the right structure depends on your income pattern, household expenses, and whether you anticipate windfalls over the next few years.
How Fixed Rates Are Priced Compared to Variable Rates
Fixed rates are not set by the Reserve Bank cash rate. They reflect the lender's view of where rates will sit over the fixed period, priced off wholesale funding costs and projected rate movements. That is why fixed rates sometimes sit below variable rates and sometimes above them, depending on market expectations.
When you apply for a home loan, the fixed rate you are offered is locked in once your loan is formally approved, not when you first enquire. If settlement is delayed or construction takes longer than expected on a house and land package, you may need to re-fix at a different rate if your rate lock period expires. Most lenders offer a rate lock for 90 days, with some extending this for construction loans.
For Central Coast buyers using the First Home Guarantee with a 5% deposit, your ability to access discounted fixed rates depends on the lender's policy for low deposit loans. Some lenders reserve their sharpest fixed rates for borrowers with at least 20% equity, while others offer the same rate regardless of deposit size. That difference can be 0.20% to 0.40%, which compounds over a three or five year fixed term.
What Happens When Your Fixed Rate Expires
At the end of your fixed period, your loan automatically rolls to the lender's standard variable rate unless you take action. That standard rate is typically higher than the variable rate offered to new customers, sometimes by 0.50% or more.
You have three options at expiry. You can revert to the standard variable rate and do nothing. You can negotiate a discounted variable rate with your current lender. Or you can refinance to another lender offering a lower ongoing rate. Most borrowers who remain engaged with their loan structure will either negotiate or refinance rather than accept the standard rate.
If you are approaching a fixed rate expiry, your lender will typically contact you 30 to 60 days beforehand with an offer to re-fix or move to a discounted variable rate. That offer is not always the most competitive available in the market. Comparing what your current lender offers against what you could access by refinancing is a straightforward exercise that can reduce your repayments by $200 to $400 per month depending on loan size and rate differential.
How to Decide Whether to Fix, and for How Long
The decision depends on your repayment capacity, how long you plan to hold the property, and whether you expect to make extra repayments in the next few years. If your income is stable, your budget is tight, and you want to eliminate repayment risk for a set period, fixing a portion of your loan makes sense. If you expect irregular income, plan to pay down debt aggressively, or may need to sell or refinance within two years, a variable loan or a split weighted toward variable gives you more control.
The fixed term you choose should match your risk tolerance and your view of the property. Fixing for one or two years gives you short-term certainty without locking you into a long-term structure. Fixing for four or five years maximises your protection from rate rises but also maximises your exposure to break costs if your circumstances change. Most first home buyers on the Central Coast who fix choose a two or three year term because it covers the highest-risk period for budget pressure without extending too far into an uncertain future.

Frequently Asked Questions
Can I make extra repayments on a fixed rate home loan?
Most fixed rate loans allow between $10,000 and $30,000 in extra repayments per year without penalty, though some lenders do not permit any additional repayments during the fixed term. Exceeding the limit or paying extra on a loan with no allowance will trigger break costs.
Do fixed rate loans come with an offset account?
Most fixed rate loans do not offer an offset account. Some lenders provide this feature on fixed loans but charge a higher interest rate that often removes the benefit of the offset.
What are break costs and when do I have to pay them?
Break costs are charged if you pay out, refinance, or exceed your extra repayment limit during a fixed rate period. The cost is calculated based on the difference between your fixed rate and the rate the lender can now earn by re-lending that money.
Should I fix my entire home loan or split it?
A split loan lets you fix part of your borrowing for repayment certainty while keeping the rest variable for flexibility with extra repayments and offset access. The right ratio depends on your need for certainty versus your ability to make lump sum repayments.
What happens when my fixed rate period ends?
Your loan automatically reverts to your lender's standard variable rate, which is usually higher than rates offered to new customers. You can negotiate a discount, re-fix, or refinance to another lender at that point.
