Mortgage Jargon Explained: 10 Home Loan Terms Every Australian Borrower Should Know
A 2026 study found that 58% of Australian homeowners don’t fully understand key mortgage terms. Things like LVR, comparison rate, and serviceability can sound like a different language.
What does all this home loan jargon actually mean?
Here’s a plain English breakdown of the 10 terms that come up most often, and what they mean for your borrowing.
LVR (Loan-to-Value Ratio)
Your LVR is the size of your loan as a percentage of the property value. If you borrow $480,000 to buy a $600,000 home, your LVR is 80%. Lenders use your LVR to assess risk. The lower your LVR, the more equity you have, and generally the better the rate you’ll be offered. Most lenders want an LVR of 80% or below to avoid LMI.
LMI (Lenders Mortgage Insurance)
LMI protects the lender, not you, if you default on your loan. It kicks in when your LVR is above 80%. The cost varies but can run into the thousands. Some buyers choose to pay LMI to get into the market sooner rather than saving a larger deposit. We’ve written a full guide on what LMI is and how to avoid it.
Comparison Rate
A comparison rate combines the advertised interest rate with most fees and charges into a single percentage. It gives you a more honest picture of the true cost of a loan. Two loans might have the same interest rate but very different comparison rates depending on their fees. Always compare both.
Serviceability
Serviceability is the bank’s way of checking you can actually repay the loan. They don’t just look at today’s rate. They test your ability to repay at a rate that’s typically 3% higher than your actual rate. This is called the serviceability buffer. Even if you’re well within budget now, the buffer helps make sure you can handle rate rises.
Offset Account
An offset account is a transaction account linked to your home loan. The balance in it offsets the amount you owe, reducing the interest you pay. If you have a $500,000 loan and $50,000 in your offset account, you only pay interest on $450,000. It’s one of the most useful features you can have on a home loan.
Redraw
Redraw lets you access extra repayments you’ve made on your home loan. If you’ve paid ahead of schedule, you can draw that money back if you need it. It’s similar to an offset account but works differently. Redraw is built into the loan itself, whereas an offset is a separate account. Not all loans include redraw, so it’s worth checking.
Fixed Rate
A fixed rate loan locks in your interest rate for a set period, usually one to five years. Your repayments stay the same regardless of what the Reserve Bank does. That predictability appeals to many borrowers. The trade-off is that fixed loans often have fewer features and can come with break costs if you exit early. We’ve covered fixed vs variable home loan rates in detail if you want to go deeper.
Pre-Approval
Pre-approval (also called conditional approval) is a lender confirming they’d be willing to lend you up to a certain amount, subject to a full assessment. It doesn’t guarantee you’ll get the loan but shows sellers you’re a serious buyer. Pre-approval usually lasts 90 days. It’s worth getting one before you start making offers.
Equity
Equity is the difference between what your property is worth and what you still owe on it. If your home is worth $800,000 and you owe $500,000, you have $300,000 in equity. As you pay down your loan and property values rise, your equity grows. Some borrowers use equity to fund renovations or buy an investment property.
Split Loan
A split loan divides your mortgage into two portions: one fixed, one variable. You get some repayment certainty with the fixed part, and flexibility with the variable part. It’s a popular middle-ground option for borrowers who don’t want to commit entirely to either. You can choose what percentage goes into each portion.
