The Pros and Cons of Comparing Home Loans

Why Loan Comparison Matters for Navy Members

Comparing home loans before you commit can save you tens of thousands over the life of your mortgage. Navy members often have access to rate discounts and features that aren't advertised publicly, which means comparison sites don't always show the full picture. A broker who works with Defence personnel knows where those benefits sit and which lenders actually follow through on them.

When you're comparing loans, you're weighing up interest rates, offset accounts, flexibility to make extra repayments, and how the lender treats deployments or postings. The loan with the lowest advertised rate isn't always the one that costs you the least or fits your circumstances.

Fixed Rate vs Variable Rate: What Changes When You Compare

A fixed interest rate locks in your repayments for a set period, usually between one and five years. A variable interest rate moves with the market, which means your repayments can go up or down. When you compare these two options, the decision comes down to certainty versus flexibility.

Fixed rates give you predictable repayments, which can be useful if you're managing a tight budget or planning for a posting. Variable rates typically come with offset accounts and the ability to make unlimited extra repayments without penalty. If you're earning allowances on deployment and want to put that income straight onto the loan, a variable rate lets you do that without restriction.

Consider a Navy member deploying for six months with sea-going allowance. They want to direct that extra income onto the loan while they're away. A variable rate loan with an offset account lets them park the funds and reduce interest daily, then access the money again if needed. A fixed rate loan may cap extra repayments at $10,000 or $20,000 per year, depending on the lender, and won't offer an offset.

Split Loans: Balancing Rate Protection and Flexibility

A split loan divides your borrowing between fixed and variable portions. You might fix half your loan amount and leave the other half variable. This gives you some rate certainty while still allowing access to features like offset accounts and unlimited extra repayments on the variable portion.

In our experience, Navy members who expect their income to fluctuate - such as those moving between sea and shore postings - often find a split structure more practical than committing entirely to one rate type. The variable portion absorbs extra repayments when income is higher, while the fixed portion keeps a baseline repayment steady.

Interest Rate Discounts: What Navy Members Should Ask For

Most lenders offer rate discounts that aren't listed on their websites. Navy members may qualify for discounts based on occupation, loan size, or deposit amount. The discount might be 0.10% to 0.70% off the standard variable rate, depending on the lender and your circumstances.

When comparing loans, ask what the actual rate will be after discounts are applied, not just the advertised rate. Some lenders also offer discounts for maintaining a package that includes home and contents insurance or holding a transaction account with them. Those package fees can add $300 to $400 per year, so factor that into your comparison.

Offset Accounts: How They Work and When They're Worth It

An offset account is a transaction account linked to your home loan. The balance in the offset reduces the amount of interest you're charged each day. If you have a loan amount of $500,000 and $20,000 sitting in your offset, you only pay interest on $480,000.

Offset accounts are only available on variable rate loans or the variable portion of a split loan. They're most useful if you keep a decent balance in the account, such as income between pay cycles or savings you're holding for a specific purpose. If your transaction account usually sits close to zero, an offset won't save you much in interest.

Loan Features That Matter on Posting or Deployment

Some lenders allow you to port your loan when you relocate, which means you can take the same loan to a new property without reapplying or paying discharge fees. This can be relevant for Navy members who buy in one location and later need to move due to a posting.

Another feature to compare is the ability to switch between owner-occupied and investment loan status if you're posted and decide to rent out your property rather than sell. Not all lenders allow this without refinancing, and those that do may charge a variation fee or adjust your interest rate.

Lenders Mortgage Insurance and How It Affects Comparison

If your deposit is less than 20%, most lenders will charge Lenders Mortgage Insurance. Navy members may qualify for LMI waivers with certain lenders, which can save several thousand dollars upfront. When comparing loans, check whether the lender offers a waiver and what conditions apply. Some lenders waive LMI for Defence personnel with a 10% deposit, while others require specific ranks or loan amounts.

LMI is a one-off cost but it's often capitalised into the loan amount, which means you pay interest on it for the life of the loan. If one lender charges LMI and another waives it, that difference can outweigh a small variation in interest rate.

Application and Approval: What to Compare Beyond the Rate

How a lender handles your application matters as much as the rate they offer. Some lenders are familiar with Defence pay structures and allowances, while others will ask for additional paperwork or query income sources that are standard in the Navy. When you apply for a home loan, ask how the lender treats allowances and whether they'll accept a letter from your pay office as evidence of ongoing income.

Some lenders also offer faster home loan pre-approval processes for Navy members, which can make a difference if you're trying to secure a property in a tight market. Pre-approval gives you a clear borrowing limit and shows sellers you're ready to proceed.

What Happens When You Don't Compare

Staying with your current lender without comparing options can cost you over time. Lenders often reserve their most competitive rates for new customers, while existing customers sit on higher rates unless they ask for a review. Refinancing to a new lender or renegotiating with your current one can bring your rate down and unlock features you didn't have before.

We regularly see Navy members who've been on the same loan for several years and haven't reviewed their rate since they first borrowed. A loan health check compares your current loan against what's available now and shows whether refinancing or negotiating would put you in a more useful position.
