A few thousand dollars in cashback can make refinancing your home loan look like an easy win. Move your mortgage to a new bank, meet the eligibility criteria and receive $2,000, $3,000 or even $4,000 after settlement.
The problem is that cashback is a one-off benefit, while the interest rate you pay is ongoing. If the lender later changes its variable rate outside the normal RBA cycle, the value of that upfront incentive can disappear surprisingly quickly.
That is why borrowers need to be cautious about choosing a lender primarily because of cashback. The better question is not how much the bank is offering you to switch, but what the loan is likely to cost you over the years that follow.
Banks don’t only move rates when the RBA does
Many borrowers associate home loan rate changes with the Reserve Bank of Australia. The RBA changes the cash rate, banks announce their response and mortgage repayments rise or fall.
But banks can also change variable mortgage rates independently of an RBA decision.
Their pricing can be influenced by funding costs, competition, customer risk, internal margins and broader commercial decisions. A lender can offer an attractive rate and cashback to win a borrower today, but that does not guarantee the loan will remain one of the most competitive options in the market.
This is where cashback chasing can become a false economy. 
A $3,000 cashback looks significant, but even a relatively small rate difference can outweigh that amount over time. On a $700,000 home loan, an additional 0.25% in interest represents roughly $1,750 a year before allowing for the declining balance and repayment structure.
The cashback gets your attention. The ongoing interest rate determines what the loan really costs.

Treat cashback as a bonus, not a reason to refinance
There is nothing inherently wrong with accepting cashback if the new loan is already the best option for your circumstances.
The mistake is starting with the cashback and working backwards.
Borrowers should first compare the interest rate, fees, loan features, refinancing costs and overall suitability of the product. Only then should cashback be considered as an added benefit.
The way the incentive is paid can also vary between lenders and is commonly tied to an eligible bank or transaction account. More importantly, cashback offers can come with conditions such as minimum loan balances, loan-to-value limits, account requirements and restrictions around how frequently an incentive can be claimed.
The headline figure rarely tells the whole story.
Refinancing too often can hurt your credit profile
There is another risk in turning refinancing into a regular cashback strategy.
Each time you formally apply for a new home loan, the lender will generally make a credit enquiry. Those enquiries form part of your credit history and can be visible to future lenders.
Refinancing occasionally for a genuine financial benefit is normal. The concern arises when someone repeatedly applies for credit over relatively short periods simply to move from one promotion to another.
A pattern of frequent credit applications can make a borrower appear more reliant on credit or financially unstable, even if the reality is simply that they have been aggressively chasing incentives.
There are also practical costs each time you move. Discharge fees, registration charges, valuations, paperwork and other refinance costs all need to be considered before deciding whether another switch genuinely leaves you better off.
You may be able to get a better rate without refinancing
One of the most overlooked options is asking your existing lender to improve your rate.
Banks regularly change their pricing, and existing customers may not always be on the most competitive rate available. In some cases, a broker can request that a lender reprice the current loan without the borrower having to refinance at all.
At UFinancial, this review process is not an optional extra or something clients need to remember to ask for. Regular home loan reviews and repricing are included as a standard part of the service for UFinancial mortgage clients.
That means our team can review whether your existing lender is still offering you competitive pricing and, where appropriate, request a better rate on your behalf. If the lender agrees, you may be able to reduce your interest rate without changing banks, lodging a new home loan application or going through a full refinance.
If your existing lender will not offer competitive pricing, that is when it makes sense to investigate the broader market and determine whether refinancing genuinely stacks up.
This is a very different strategy from simply jumping to whichever bank happens to be advertising the largest cashback.
The smarter strategy is regular home loan reviews
Finding a competitive home loan at settlement is important, but keeping it competitive is just as important.
Rates change. Lender appetite changes. Property values move. Your equity position improves. New products enter the market and banks adjust the discounts available to different borrowers.
UFinancial mortgage clients benefit from an ongoing review process designed to help identify whether their current loan remains competitive. If there is an opportunity to reprice with the existing lender, that can be explored first. If not, the broader market can be reviewed to determine whether refinancing would produce a genuine financial benefit.
For a small sole-operator broker, systematically reviewing and repricing an entire client book can be difficult because their time is often focused on writing new loans and managing settlements. A larger team has the capacity to make ongoing loan reviews part of the service rather than relying on the borrower to realise years later that their rate is no longer competitive.
The goal should not be to refinance as often as possible. It should be to make sure your mortgage remains competitive and only refinance when there is a genuine financial reason to do so.
Frequently asked questions
Can I refinance my home loan multiple times during the year?
There is generally nothing preventing an eligible borrower from refinancing more than once during a year, provided they continue to meet the lending criteria of the new lender.
However, each move can involve another credit enquiry, discharge and registration costs, paperwork and potentially other fees. Some cashback promotions also impose conditions around how long the loan needs to remain open or how frequently an incentive can be claimed.
Before refinancing again, it is worth calculating the total financial benefit rather than looking only at the advertised incentive.
What happens to my credit report if I refinance a lot?
A formal home loan application will generally result in a credit enquiry appearing on your credit report.
A few enquiries over time are normal, but numerous applications within a short period can influence a lender’s assessment because frequent requests for new credit may indicate higher risk.
This is one reason borrowers should compare their options carefully before lodging applications rather than applying with several lenders simply to see what they can obtain.
How do I find the best home loan interest rate?
There is no single lender that always offers the best rate for every borrower.
The pricing available to you can depend on your loan amount, property value, loan-to-value ratio, whether the property is owner-occupied or an investment, the type of loan you require and your broader financial circumstances.
A mortgage broker can compare lenders based on your individual position and also investigate whether your existing bank is prepared to reprice your current loan before recommending that you refinance.
The most important comparison is not which bank has the biggest promotion. It is which loan gives you the strongest overall financial outcome.
When did you last review your home loan?
If your mortgage hasn’t been reviewed recently, you don’t need to wait for another bank to advertise a cashback offer.
Speak with a UFinancial mortgage broker to find out whether your existing lender can offer you a better rate or whether there may be a more competitive option elsewhere.
