Fixed Rate Loans and Extra Repayments: What Not to Do

Fixed Rate Loans and Extra Repayments: What Not to Do

Most fixed rate home loans cap your extra repayments at $10,000 to $30,000 per year.

Exceed that limit and you'll trigger break costs, which can run into thousands of dollars depending on how far rates have moved since you locked in. For NSW Ambulance workers buying their first property, understanding what you can and cannot do with a fixed rate loan before you sign matters more than the headline rate itself.

Why Fixed Rates Come With Repayment Limits

Lenders fund fixed rate loans by borrowing money at a locked wholesale rate for the same term you choose. When you pay more than the agreed amount early, the lender loses the interest it anticipated and may still owe money on its own borrowing arrangement. The repayment cap protects the lender from that loss. Most lenders allow between $10,000 and $30,000 in extra repayments each year without penalty, though some allow none at all. If your income allows regular overpayments or you expect lump sums from shift penalties or overtime, a fixed rate loan with a low or zero extra repayment allowance will cost you flexibility you might need.

Consider a paramedic working a mix of rostered and relief shifts who puts down a 5% deposit under the Australian Government 5% Deposit Scheme. They lock in a three-year fixed rate with a $20,000 annual extra repayment cap. In year one, they pay an additional $15,000 from accumulated overtime and shift allowances. In year two, they receive a $25,000 payout from leave entitlements and attempt to add it all to the loan. The lender applies break costs on the $5,000 above the cap, which in a falling rate environment might amount to $1,200 or more. The overpayment that was meant to reduce interest instead incurs a fee larger than the saving it would have generated.

The Case for Splitting Your Loan Between Fixed and Variable

A split loan divides your borrowing into two portions, one fixed and one variable, each with its own interest rate and repayment terms. The variable portion allows unlimited extra repayments and usually comes with an offset account. The fixed portion gives you rate certainty on the majority of the loan. Splitting lets you make additional payments when your income allows without triggering penalties, while still protecting most of your repayment from rate rises. The exact split depends on how much surplus income you expect to direct toward the loan each year. A 70/30 or 60/40 split between fixed and variable is common, though the proportions should reflect your actual capacity to make extra payments rather than an arbitrary rule.

In our experience, NSW Ambulance workers who receive regular overtime or penalty rates benefit from keeping at least 30% of the loan variable so they can absorb those earnings without restriction. The variable portion also gives you access to features like offset accounts, which reduce interest on the outstanding balance without formally making an extra repayment. If you're saving for furniture, a car, or upcoming leave, parking that money in an offset account attached to the variable portion cuts your interest cost while keeping the funds accessible.

Redraw Facilities Are Not the Same as Offset Accounts

A redraw facility lets you withdraw extra repayments you've already made, subject to lender approval and sometimes fees. An offset account is a transaction account linked to your loan where the balance reduces the interest charged on your home loan without being locked into the loan itself. The distinction matters because redraw can be restricted or removed by the lender, particularly during financial stress or policy changes. Offset balances remain your money in your account and cannot be touched by the lender. If you plan to make extra repayments and may need access to those funds later, an offset account on the variable portion of a split loan offers more control than relying on redraw. Many fixed rate loans do not offer offset accounts at all, and those that do often charge a higher interest rate for the feature.

When comparing home loan options as a first home buyer, check whether the fixed rate product includes redraw, what conditions apply, and whether fees are charged each time you withdraw. If the lender's redraw policy requires a minimum withdrawal amount or restricts access during certain periods, the feature may not deliver the flexibility you expect.

How First Home Buyer Concessions Affect Your Deposit and Loan Structure

NSW offers a full stamp duty exemption on properties up to $800,000 and a sliding concession up to $1,000,000 for eligible first home buyers. If you're purchasing a new build or substantially renovated home under $600,000, or a land and build package under $750,000, you may also qualify for the $10,000 First Home Owner Grant. These concessions reduce the upfront cost of buying, which means you can either put down a larger deposit or retain more savings for furniture, moving costs, and initial loan repayments. A larger deposit reduces your loan size, which in turn reduces the total interest you'll pay over the life of the loan and can also improve the interest rate a lender is willing to offer. If you're using the 5% deposit scheme, the stamp duty saving doesn't increase your deposit percentage but it does mean you keep more cash in hand after settlement.

Some buyers apply the stamp duty saving toward the deposit to reduce their loan size. Others keep it liquid in an offset account to reduce interest while maintaining access to the funds. If you're splitting your loan, directing that cash into an offset account on the variable portion delivers interest savings equivalent to making an extra repayment, without locking the money away.

What Happens When Your Fixed Rate Ends

At the end of your fixed term, your loan automatically rolls to the lender's standard variable rate unless you take action. Standard variable rates are typically higher than discounted variable or new fixed rates available in the market at that time. Most lenders will contact you 30 to 90 days before the fixed term expires and offer you the option to refix or move to a discounted variable product. If you do nothing, you'll start paying the higher standard rate from the day after your fixed term ends. Refinancing to another lender or negotiating a lower rate with your current lender are both options worth considering at that point. The refinancing process takes time, so if you're considering a switch, start the conversation at least 60 days before the fixed term expires to avoid rolling onto the standard rate while the new loan is being processed.

When your fixed rate expires, your loan also becomes fully flexible. You can make unlimited extra repayments, access an offset account if the new product includes one, and redraw without restriction if redraw is part of the loan terms. If you were constrained by a low extra repayment cap during the fixed period, the end of that term is the moment to redirect surplus income toward the loan balance.

Applying for Your First Home Loan as an NSW Ambulance Worker

Lenders assess your application based on your income, employment history, debts, living expenses, and the deposit you've saved. NSW Ambulance employment is viewed as stable and secure, which works in your favour during the assessment. If you're a permanent employee, most lenders will include your base salary plus regular overtime and allowances when calculating your borrowing capacity. Casual or relief paramedics may need to provide additional payslips or a letter from NSW Ambulance confirming hours worked. Lenders typically want to see three to six months of payslips, recent bank statements, and proof of your deposit source. If part of your deposit is a gift from family, the lender will ask for a signed declaration confirming the funds are not a loan and do not need to be repaid.

Pre-approval gives you a clear borrowing limit before you start looking at properties and shows sellers you're a serious buyer. It's not a guarantee, because the lender will still conduct a full assessment once you find a property, but it reduces the risk of making an offer you cannot fund. Pre-approval is usually valid for three to six months, which gives you time to search without rushing.
