A Money.com.au survey found 58% of homeowners don't fully understand key mortgage terms. Here's what LVR, offset, redraw, LMI and comparison rates mean for your loan.
Most Australian homeowners don’t fully understand key mortgage terms. A Money.com.au survey found 58% admit they don’t, with loan-to-value ratio (LVR) the most misunderstood, followed by offset accounts, redraw, lenders mortgage insurance (LMI) and comparison rates. Understanding these terms helps you avoid paying more interest or fees than you need to.
More than half of Australian homeowners do not fully understand key home loan concepts, with many turning to social media and artificial intelligence for financial guidance instead of professional advice.
The national survey by Money.com.au included more than 1,000 Australians.
Which mortgage terms confuse homeowners most?
The loan-to-value ratio was identified as the most misunderstood concept, with 26% of respondents saying they do not understand it. This figure affects borrowing eligibility, interest rates and whether a borrower must pay Lenders Mortgage Insurance.
Redraw facilities and offset accounts followed closely behind, with 17% unsure how either works. LMI itself confused 16% of those surveyed, whilst comparison rates were unclear to 14%. One in 10 homeowners said they do not fully understand home equity.
| Mortgage term | Don’t fully understand |
|---|---|
| Any key mortgage term | 58% |
| Loan-to-value ratio (LVR) | 26% |
| Redraw facilities and offset accounts | 17% |
| Lenders mortgage insurance (LMI) | 16% |
| Comparison rates | 14% |
| Home equity | 1 in 10 |
The confusion was not limited to younger borrowers. Gen Z and Millennials each recorded a 61% rate of confusion around key loan concepts, whilst Gen X came in at 58% and Baby Boomers at 59%.
The findings come as more Australians are actively reviewing their home loans. According to data cited by the Australian Banking Association, more than 640,000 homeowners refinanced their mortgages in 2025, a record level and a 20% increase from the previous year.
The “Facebook and AI university”
Money.com.au mortgage expert Nick Burgess attributed part of the problem to borrowers turning to unverified online sources for financial guidance.
“If you don’t have a firm grasp on basic mortgage terms and features, you’re likely not maximising your loan’s potential and could end up paying more interest over the loan’s life or dragging out your mortgage for longer than you need to,” Mr Burgess said.
He said too many borrowers were relying on generic online information and social media opinions to understand how mortgages work. One in five Australians say they trust AI tools like ChatGPT for home loan information.
“Too many borrowers are graduating from what I’d call the Facebook and AI university,” Mr Burgess said.
Mr Burgess described real-world consequences of the knowledge gap, including a first-home buyer in Sydney who attempted to refinance without realising their LVR remained above 80%, which would have triggered another LMI payment. Another couple kept $200,000 in a standard savings account rather than an offset account because no one had explained how offset accounts reduce interest charges.
Mortgage terms explained
LVR (loan-to-value ratio)
LVR is your loan as a percentage of the property’s value, as assessed by the lender. A $500,000 loan on a property valued at $625,000 is an 80% LVR. Above 80%, most lenders charge LMI, and some offer better rates at lower LVRs. As you repay the loan or the property rises in value, your LVR falls.
LMI (lenders mortgage insurance)
LMI protects the lender if you can’t repay and the property sells for less than the loan. You pay for it, but it covers the lender. It usually applies when your LVR is above 80%, and it doesn’t transfer to a new lender, which is why the Sydney borrower in Mr Burgess’s example faced paying it twice. Eligible first home buyers using the 5% deposit scheme can buy without LMI. See also our low deposit home loans.
Offset account vs redraw
An offset account is a transaction or savings account linked to your loan. Its balance is subtracted from the loan before interest is calculated. Using an illustrative rate of 6.00% p.a., $200,000 sitting in an offset account would reduce interest by roughly $12,000 a year compared with leaving it in a standard savings account, before considering any savings interest and tax. This is an illustration only and not a quote.
Redraw lets you access extra repayments you’ve already made into the loan. It can achieve a similar interest saving, but the money sits inside the loan, and lenders may set minimum redraw amounts, charge fees or restrict access.
| Offset account | Redraw facility | |
|---|---|---|
| Where the money sits | A separate account linked to the loan | Inside the loan as extra repayments |
| Effect on interest | Reduces the balance interest is charged on | Reduces the loan balance itself |
| Access to funds | Like a normal transaction account | Request a redraw, may have limits or fees |
| Typically available on | Variable rate loans, sometimes fixed | Most variable loans, limited on fixed |
| If you buy another property | Money stays yours and can be used as a deposit | Using redrawn funds can complicate tax deductibility |
Comparison rate
The comparison rate combines the interest rate and most fees and charges into one annual figure. Two loans with the same advertised rate can have different comparison rates if one has higher fees. It’s calculated on a standard loan amount and term, so it’s a guide rather than an exact cost.
Home equity
Equity is the difference between your property’s value and what you owe. If your home is worth $800,000 and your loan balance is $500,000, you have $300,000 in equity. Lenders typically let you borrow against part of it, as our guide to using equity to buy an investment property explains.
Ask the questions
“Your mortgage is likely the biggest debt you’ll ever take on, so it pays to understand key concepts like LVR, how the comparison rate differs from the advertised rate, and the difference between an offset account and a redraw facility,” Mr Burgess said.
“If you’re unsure about anything, don’t be afraid to ask your lender or broker to break it down for you.”
If you’re one of the many homeowners reviewing your loan, start with these questions to ask before refinancing and the refinancing traps to avoid. Our guide to fixed vs variable home loans explains how offset and redraw differ between the two.
A broker can explain each feature in plain language and compare home loans or a refinance for your situation. Attain Loans is a mortgage broker in Melbourne’s west that takes the time to walk borrowers through their options, subject to each lender’s assessment.
