You’re probably paying too much for your mortgage. It may seem confronting, but the data shows most Australians are overpaying unless they review and refinance their home loan regularly. With refinancing activity surging 135% year-on-year and mortgage broker usage at peak levels, more Australian homeowners are realising that loyalty to their current lender can mean missed opportunities and thousands in “loyalty tax”.

When comparing refinancing options, the debate of mortgage broker vs direct lender is about far more than just headline rates (though those matter). It’s about the breadth of your options, the expertise behind your choices, and how you can secure the most value over the long run.

The Refinancing Reality Check: Why Most Aussies Overpay

Recent data from the Reserve Bank of Australia reveals that existing customers pay an average of 0.41% more than new customers on their home loans with the same lender. On a $500,000 mortgage, that’s an extra $2,050 per year or a staggering $61,500 over your loan’s life.

This “loyalty tax” exists because lenders design eye-catching rates to lure new business while steadily increasing costs for their existing customers knowing the majority won’t shop around. While this practice is legal, it can seriously erode your wealth over time.

I learned about the “loyalty tax” the hard way. Years ago, when I refinanced my first property, I admit I barely questioned my direct lender. I’d been with the same bank since uni, they greeted me by name at the branch, and it felt almost disloyal to shop around or challenge their rate. But two years later, I was chatting with a friend who worked as a mortgage broker, and she offered to do a quick comparison for fun. The result floored me: sticking with my bank had cost me nearly $7,000 in unnecessary interest. That gut-punch moment was my wake-up call, not just about the cost of convenience, but about how easy it is to fall for what feels “safe” when real savings are left on the table. That experience changed the way I approached every other lending decision. Now I tell anyone who’ll listen: loyalty is nice in theory, but when it comes to your mortgage, it pays literally to be a little ruthless and see what the market (and a good broker) can actually do for you.

This is precisely why the mortgage broker vs direct lender comparison is so important. While your current bank or direct lender can only offer their own refinancing options, mortgage brokers can choose from 30+ lenders, giving you access to deals you may never find on your own and often helping you avoid the loyalty tax that quietly eats into your finances.

Mortgage Brokers: The Case for Better Refinance Rates and Deals

The numbers speak for themselves: more than 70% of Australians now trust mortgage brokers for home loans and refinancing a number that’s surged alongside record increases in broker-facilitated refinances. Here’s why.

Access to More Lenders and Competitive Comparison

Engaging with your bank or a direct lender leaves you reliant on a single institution’s products, often at rates tied to your existing relationship. Mortgage brokers, however, can compare rates and features across more than 30 different lenders, quickly finding not only better rates but also products that better suit your particular needs.

Many lenders have promotional rates or unique loan features that may not be available through direct applications. A mortgage broker can find a lender offering a better rate, improved redraw facilities, or lower overall fees, potentially equalling tens of thousands of dollars saved over the life of your loan.

Expertise in Loan Structuring and Maximising Benefits

Mortgage brokers bring strategic value, especially for borrowers with nuanced requirements such as property investors. They understand how to structure loans whether it’s splitting between fixed and variable, seeking tax effectiveness, or leveraging offset accounts and flexible repayment options.

A good broker will know which lenders are more flexible, which are actively seeking new business, and which have the most accommodating assessment criteria at any given time.

Avoiding Pitfalls such as Cross-Collateralisation

Brokers are adept at avoiding unwelcome lending traps like cross‑collateralisation, where a bank might secure your loan against multiple properties. A mortgage broker can recommend lenders who don’t require you to tie up all your assets, allowing you to maintain ownership flexibility.

Saving You Time and Boosting Negotiation Leverage

Above all, mortgage brokers manage much of the paperwork, legwork, and negotiation involved in refinancing. They leverage their relationships and volume of business to advocate on your behalf, often securing more competitive deals than individual borrowers could achieve alone.

Direct Lenders: When Going Direct Might Be the Better Refinance Option

Even with the advantages of mortgage brokers, there are scenarios where contacting a direct lender may still make sense.

Benefits of Existing Relationships

If you have a strong relationship with your lender, hold multiple products, or are considered a high-value customer, you may qualify for exclusive retention offers. Some banks use internal retention teams to make special offers when customers enquire about refinancing or threaten to leave.

Simpler, Faster Transactions

For straightforward refinancing needs (such as a simple rate reduction or minimal changes to structure), a direct lender can be a quick and hassle-free option. This is especially relevant if you prefer hands-on control or want to avoid adding another party to the process.

When Time Is of the Essence

In urgent situations for example, if your fixed rate is about to expire and you need an immediate solution direct dealings with your lender may enable quicker processing.

The PropertyChat.ai Perspective: Brokers Often Deliver Superior Outcomes

Insights from PropertyChat.ai reinforce that mortgage brokers provide significant advantages, particularly for borrowers seeking the best refinance rates and features, or for property investors requiring specialised structuring.

Brokers maintain up-to-date knowledge of which lenders have the best offers, which have adjusted lending criteria, and which are motivated to win new business with unpublished or broker-only rates. For investors, brokers understand how to tailor structures to support long-term strategies and maximise wealth creation.

Quantifying the Loyalty Tax: The Real Cost of Not Refinancing

The “loyalty tax” is not a myth. RBA data demonstrates the annual extra cost existing borrowers pay compared to new customers:

• $300,000 loan: $1,230 per year extra ($36,900 over 30 years)
• $500,000 loan: $2,050 per year extra ($61,500 over 30 years)
• $700,000 loan: $2,870 per year extra ($86,100 over 30 years)

These are real savings, money that could be building your wealth, funding your lifestyle, or supporting your next property investment.

Making the Choice: Mortgage Broker vs Direct Lender Refinancing

It comes down to your personal circumstances and preferences:

Consider a broker if you:

• Haven’t reviewed your mortgage in over a year
• Want to compare multiple lenders and options
• Have a complex financial situation or own investment properties
• Value tailored professional advice and negotiation support
• Prefer someone else to manage the paperwork

Consider a direct lender if you:

• Have a long-term, strong relationship with your bank
• Only need a simple rate adjustment with minimal changes
• Prefer a self-managed approach
• Need urgent processing

Red flags suggesting you need a broker:

• Current rate is above 6%
• No refinancing in the last two years
• Your lender’s rate rises have exceeded the RBA cash rate increases
• Unexplained loan fees or unclear costs

The Bottom Line: Take Control, Avoid the Loyalty Tax

Evidence shows mortgage brokers usually secure better refinancing rates and loan products for most Australians. Their access, expertise, and negotiation power mean significant financial benefits compared with sticking with your direct lender out of convenience.

Regardless of your path, what matters most is taking action, reviewing your mortgage regularly, and ensuring you aren’t left subsidising your lender’s margins via a loyalty tax. Check your current rate, seek competing offers, and consider advice from an experienced mortgage broker.

The $60,000 Loyalty Tax You’re Secretly Paying

0:00So, you’re thinking about refinancing

0:01your home loan and you’ve got a big

0:03decision to make. Do you stick with your

0:04current bank or do you see what a broker

0:06can find for you? Today, we’re going to

0:08cut through all the noise and figure out

0:10who really gives you the better deal and

0:12how you can make the absolute smartest

0:14choice for your money. All right, let’s

0:15just jump right in with a statement that

0:17might sting a little, but honestly, the

0:20data really backs it up. For most of us

0:22homeowners, just sticking with what we

0:24know could be costing us a small

0:26fortune. The real question is why? Well,

0:29the main culprit has a name, and it’s

0:31called the loyalty tax. Yeah, it sounds

0:33a bit sneaky, and frankly, it is. It’s

0:36this hidden cost you pay for staying

0:37put. And we’re about to pull back the

0:39curtain and show you exactly how it

0:41works. So, what is this thing exactly?

0:44Put simply, banks are always trying to

0:46get new business, right? So, they roll

0:48out these amazing, super low interest

0:51rates to lure new customers in the door.

0:53but for their existing loyal customers,

0:56well, those shiny new rates often don’t

0:58get passed on, you end up paying more

1:00than a complete stranger walking it off

1:02the street for the exact same product.

1:05And look, this isn’t just some abstract

1:07theory. This has a real world cost. Take

1:09this story from our source material. A

1:11homeowner had a friendly chat with a

1:12broker and discovered that just 2 years

1:15of loyalty had cost them nearly $7,000

1:18in interest they didn’t need to pay.

1:20Think about that for a second. That’s a

1:22family vacation, a kitchen upgrade, a

1:24huge boost to your savings, just gone.

1:27That kind of gut punch moment is

1:29something we all want to avoid, right?

1:31So, how do you actually fight back

1:33against this loyalty tax? It really all

1:35boils down to a choice between two very

1:37different ways of refinancing your

1:39mortgage. Okay, let’s break it down. On

1:42one side, you have the mortgage broker

1:44who shops around at dozens of lenders

1:46for you. On the other, you have the

1:47direct lender. That’s your bank where

1:49you’re pretty much handling the whole

1:50thing yourself. One offers a massive

1:53amount of choice. The other offers

1:55familiarity. Let’s dig in and see which

1:57one really comes out on top. First up,

2:00let’s talk about brokers. There is a

2:02very good reason they have become the

2:04go-to choice for a huge number of

2:05homeowners. It all comes down to

2:07leveraging the power of competition. I

2:10mean, just look at these numbers. Over

2:1270% 70% of Australians now use a

2:15mortgage broker for their home loans.

2:17This isn’t some niche choice anymore. It

2:19is the mainstream path and that shows a

2:21massive shift in how people are finding

2:23the best value. So why the big switch?

2:26Well, a broker gives you access to a

2:28massive panel of lenders, not just one.

2:31They bring expertise, helping you

2:32structure your loan to save money and

2:35avoid really nasty traps like crossc

2:37collateralization. You do not want to

2:39get tangled up in that. Plus, let’s be

2:41honest, they handle the mountains of

2:43paperwork and use their industry clout

2:44to negotiate a much better deal than you

2:46could probably get on your own. But hang

2:48on, it’s not a total slam dunk for

2:50brokers. To be fair, going directly to

2:52your bank isn’t always the wrong move.

2:55There are some very specific situations

2:57where the direct approach can actually

2:58be the simpler and sometimes even the

3:00smarter option. So, when does it make

3:02sense? Well, if you’re a high-value

3:04customer, your bank might have a special

3:05retention team ready to cut you a deal

3:07to keep you. or if what you need is

3:09really simple, like just a rate cut with

3:11no other changes. Maybe you’re a DIY

3:13type who really likes to be in the

3:15driver’s seat. And finally, if you’re in

3:17a massive hurry, like your fixed rate is

3:19about to expire tomorrow, going direct

3:21can sometimes be a bit faster. Now,

3:23let’s circle back to that loyalty tax.

3:25We’ve talked about it as an idea, but

3:26what does it actually look like in

3:28dollars and cents? Well, thanks to some

3:30data from the Reserve Bank of Australia,

3:32we can put some hard numbers on the cost

3:34of just doing nothing. So, get this. The

3:37RBA found that on average, existing

3:40customers are paying 0.41%

3:42more in interest than new customers at

3:45the exact same lender. It might not

3:48sound like much, but that tiny

3:49percentage snowballs into a huge

3:51problem. Let’s translate that into real

3:53money. On a typical half a million

3:55dollar mortgage, that 41% difference

3:58costs you an extra $2,050

4:01every single year. That’s over two grand

4:03you’re giving the bank for no reason

4:05other than loyalty. And here is where

4:07the damage really, really adds up. Over

4:10the full 30-year life of that same loan,

4:12you are looking at a staggering $61,500

4:16in extra payments. That is the real

4:18tangible cost of the loyalty tax. It’s

4:21not just a number on a page. That’s a

4:22car, a university education, a huge part

4:25of your retirement nest egg. Okay. So,

4:28armed with all this information, how do

4:30you decide what to do? It’s not about a

4:33one-sizefits-all answer. It’s about

4:35looking at your specific situation and

4:37choosing the path that actually aligns

4:38with your needs. You should probably

4:41lean towards a broker if it’s been a

4:42while since you’ve checked your rate, if

4:44you want to see all your options laid

4:46out, or if your finances are a bit

4:48complex, especially if you’re a property

4:50investor. If you value expert advice and

4:53absolutely hate paperwork, a broker is

4:56your advocate. On the other hand,

4:58consider going direct if you have that

5:00strong high value relationship with your

5:02bank and can get a great deal or if you

5:04just need a simple rate cut, nothing

5:06more. If you prefer to manage the

5:08process yourself or you’re in a real

5:09time crunch and need a fast outcome, it

5:11can also be the right choice. The

5:13crucial point is to match the path to

5:15your specific circumstances. Ultimately,

5:18it really all boils down to this one

5:20single powerful question. Every extra

5:22dollar you pay in interest is a dollar

5:24that pads your lender’s profits. Are you

5:26okay with that? Or are you ready to put

5:28that money back where it belongs, in

5:29your own pocket? If you’re ready to take

5:32control and stop paying that loyalty

5:34tax, your next step is to get informed.
