Fixed vs Floating: Why Getting Advice for Your Own Financial Situation Matters

Fix or float your mortgage in 2025? Here’s what to consider.

Thinking about whether to fix your mortgage or go floating in 2025? It’s a big decision—and the right answer really depends on your personal situation.

In this month’s blog, alongside my usual updates, I’ve added my two cents on using AI ‘Robo Advice’ and Gen AI for financial advice—something we’re hearing more about in financial circles lately. Robo Advice has been around for a while, and while Gen AI is an interesting development, the real takeaway remains the same: no matter how many Robo or AI tools are out there, nothing beats custom advice that’s tailored to your own personal situation and can adapt with you.

Do I Give Different Advice to Different Clients?

I get asked this a lot: “Does your advice change depending on who you're working with?”

On one level, the answer is no—interest rates are the same for everyone. So there are some general wealth principles that can always be applied.


But on another level, it’s a definite yes—because people’s situations, goals, and comfort levels are all different, and so the strategy needs to reflect that too.

This is why it is super important to get personalised advice, rather than just relying on ChatGPT!

Where Are Mortgage Rates Sitting Right Now? (Mid-2025)

  • 1-year and 2-year fixed rates: Around 4.9%
  • 18-month rates: Slightly lower
  • 3- to 5-year fixed rates: Climbing from 5% to about 5.5%

There’s talk of rates easing down later this year, but let’s be honest—there’s a lot of global uncertainty. Tariffs, wars, oil prices, inflation, or a sluggish economy could all throw predictions off. So, take any forecast with a grain of salt.

Fixed vs Floating: What Are Your Options?

Ok, so those are the rates. Everyone has the same basic choices:

  • Try to pick the lowest rate and guess where things are heading
  • Or hedge your bets by splitting your loan across different fixed terms

But here’s the thing: What you do with your surplus income matters more than how long you fix your loan for.

And here is something else even more important than that - not everyone is in the same boat when it comes to mortgages, and one size financial advice does not fit all.

So it pays to get personalised advice for your mortgage strategy.

Tailoring Mortgage Advice to Real People

So on that note, here are some things I would discuss with my different clients in different situations, that may matter even more than where interest rates are sitting at.

First-Time Homebuyers

  • Many want certainty in their repayments for the first year or two
  • Some are ready to talk debt reduction from day one
  • We often set up offset loans or revolving credit to help them get ahead faster

Clients with Tight Budgets

For these clients, I might recommend: to:

  • Fix all your loans to avoid surprises
  • Possibly split terms to soften the blow of future rate changes

Clients with Surplus Income

Tips I would suggest would include:

  • Focus on a debt reduction strategy that suits your lifestyle
  • Use offset accounts or revolving credit
  • Increase repayments where possible

Property Investors

Usually need to:

  • Consider interest-only loans for tax efficiency
  • Work with an accountant to structure loans for maximum benefit
  • Discuss legal structures, entity separation, and spreading loans across banks

So, Does the Advice Change?

Yes and no.


The rates are the same, but the strategy depends on you—your goals, your risk tolerance, and your financial situation.

Getting your mortgage strategy and repayment plan right could make a big difference to how comfortable you are now financially and the term of your loan.
AI is great for understanding the basics but is not always correct, or the complete solution

A word to the Wise on Robo/AI Advice...

There is a lot of talk in the town of people seeking financial advice from ChatGPT or other types of Gen AI. Gen AI can be really helpful when you’re trying to understand how mortgages work — things like interest rates, fixed vs floating, or what banks look for when you apply. It’s brilliant for breaking down the basics.

But remember, everyone’s situation is different. Some people are buying their first home, others are investing. Some have stable income, others are self-employed. Some want to pay off fast, others want lower repayments. So, one-size-fits-all advice doesn’t really work when it comes to mortgages, or any financial strategy for that matter.

So be careful about just blindly following advice from ChatGPT - or any AI. It doesn’t know your full story — your budget, your long-term plans, or what stage you’re at and what risk factors you have. It can't predict the future. It’s great for learning and getting ideas, but when it comes to making real decisions about a mortgage, it’s better to talk to professionals who understand your situation properly — like your financial adviser and professional team (lawyers, accountants etc.)

Professional advice might come with a price tag—but as any good builder, lawyer, accountant, electrician, or doctor will tell you, it’s worth getting it right the first time. Why? Because they’re often the ones called in to fix the fallout when shortcuts don’t go to plan!

That's all for this month, next update in July.
