What Actually Makes Up the Cost of a Home Loan
The cost of a home loan includes the interest rate, ongoing account fees, and upfront charges such as application fees, valuation fees, and settlement costs. For Hawthorn buyers, where property values typically sit well above the Victorian regional threshold, the impact of even small percentage differences compounds quickly over the life of a loan.
A borrower securing a loan of $800,000 at current variable rates might pay between $2,500 and $4,000 in upfront costs before the first repayment is made. Ongoing monthly account fees of $10 to $15 add another $3,600 to $5,400 over a typical 30-year term. Lenders mortgage insurance can add significantly more for buyers with deposits below 20 per cent.
Lenders Mortgage Insurance and How It Affects Your Loan
Lenders mortgage insurance is required when your deposit is below 20 per cent of the property value. The premium is calculated on a sliding scale based on your loan amount and loan to value ratio, and it protects the lender, not you.
Consider a buyer purchasing in Hawthorn with a 10 per cent deposit. On a property at the suburb's current median, LMI could add $20,000 to $30,000 to the cost of borrowing. That premium can be paid upfront or capitalised into the loan, but either way it represents a substantial additional cost. The Australian Government 5% Deposit Scheme allows eligible first home buyers to avoid LMI by securing a government guarantee in place of the shortfall, bringing the combined deposit and guarantee to 20 per cent. Blue Lion Lending works with lenders on the Housing Australia panel to assess whether this scheme applies to your situation.
Rate Discounts and How to Access Them
Most lenders publish a standard variable rate but offer rate discounts based on factors including loan size, deposit size, and whether you hold an offset account. The discount typically ranges from 0.30 to 1.00 percentage points below the standard rate.
In our experience, buyers in Hawthorn often qualify for larger discounts due to higher loan amounts and strong serviceability. A discount of 0.70 percentage points on an $800,000 loan can reduce repayments by over $300 per month compared to the standard rate. Rate discounts are not automatically applied. They are negotiated at the time of application and may be reviewed when you refinance or if you switch loan products with the same lender.
Offset Accounts and How They Build Equity Faster
An offset account is a transaction account linked to your home loan. The balance in the offset reduces the interest charged on your loan without affecting your repayment amount, meaning more of each repayment goes toward reducing the principal.
A borrower with $50,000 in a fully linked offset account on an $800,000 loan only pays interest on $750,000. At current variable rates, this saves roughly $2,500 per year in interest and shortens the loan term by several years. Some lenders charge a monthly fee for offset accounts, typically $10 to $20. The fee is justified if you maintain a meaningful balance in the account. If your offset balance rarely exceeds a few thousand dollars, the fee may cost more than the interest saved.
Fixed Rate, Variable Rate, or Split Loan Structure
A fixed interest rate home loan locks in your rate for a set period, usually one to five years. A variable rate moves with the lender's standard rate, which may increase or decrease over time. A split loan divides your borrowing between fixed and variable portions.
Fixed rates offer certainty but typically come with restrictions. Most fixed rate products limit extra repayments to $10,000 to $30,000 per year and charge break costs if you refinance or sell during the fixed period. Variable rates offer full flexibility for extra repayments and access to features such as offset accounts and redraw facilities. A split loan structure allows you to lock in part of your rate while retaining flexibility on the remainder. This can be useful if you expect income variability or want to make lump sum repayments from bonuses or other sources.
Application Fees, Valuation Fees, and Settlement Costs
Application fees range from $0 to $900 depending on the lender. Some lenders waive the application fee as part of a promotional offer, while others charge a flat rate regardless of loan size. Valuation fees cover the cost of the lender's property assessment and typically range from $200 to $400 for a standard residential property in Hawthorn. Settlement fees, which cover the lender's legal and administrative costs at settlement, range from $150 to $600.
These costs are usually non-negotiable once you have selected a lender, but they vary significantly between lenders. When comparing home loan options, the total upfront cost can differ by $1,500 or more. A lender offering a lower interest rate may charge higher upfront fees, which affects the overall cost depending on how long you hold the loan.
Interest Only Versus Principal and Interest Repayments
An interest only loan requires you to pay only the interest portion of the loan for a set period, typically one to five years. Principal and interest repayments include both interest and a portion of the loan balance, which reduces the amount you owe over time.
Interest only repayments are lower in the short term, which can improve cash flow, but you do not build equity during the interest only period. For owner occupied home loan purposes, interest only structures are generally used by buyers who expect a significant income increase or plan to sell within a few years. For investment loans, interest only repayments maximise the tax-deductible interest component, though changes to negative gearing from the 2027-28 income year mean losses on properties purchased after 12 May 2026 can only be offset against other residential property income.
Portable Loans and Avoiding Discharge Fees
A portable loan allows you to transfer your existing loan to a new property without discharging and reapplying. This can save you discharge fees, application fees, and valuation fees when you move.
Discharge fees typically range from $300 to $500. If you are moving within a few years of taking out your loan, portability avoids these costs and allows you to retain your existing rate and loan features. Not all lenders offer portability, and those that do may impose conditions such as a maximum loan to value ratio or require the new property to be owner-occupied. Portability is rarely mentioned in loan documentation but can be confirmed with your broker before you apply.
Monthly Account Fees and Package Discounts
Monthly account fees, also called ongoing fees or service fees, range from $0 to $15 per month depending on the loan product. Some lenders bundle home loans with transaction accounts, credit cards, and insurance products in a package that includes a discounted interest rate and waived account fees in exchange for an annual package fee of $300 to $400.
Whether a package saves you money depends on the rate discount offered and whether you use the bundled products. A package that waives a $15 monthly account fee and offers a 0.15 percentage point rate discount on an $800,000 loan saves roughly $1,400 per year in interest and fees, which more than covers the $395 annual package fee. If the rate discount is only 0.05 percentage points, the package may not be worthwhile.
How Serviceability Buffers Affect Borrowing Capacity
APRA requires lenders to assess your ability to service a home loan at a rate at least 3.0 percentage points above the loan product rate. This buffer ensures you can still afford repayments if rates rise.
The buffer reduces your borrowing capacity compared to what the actual repayment amount would suggest. A borrower who can afford repayments on a loan at current variable rates may only be approved for a loan at a rate 3.0 percentage points higher. For Hawthorn buyers, where property values are high, the buffer can limit how much you can borrow even if your income and deposit are substantial. Choosing a loan with a slightly higher rate but lower fees may not increase your borrowing capacity, because the serviceability assessment is still based on the loan rate plus the buffer. You can estimate your borrowing capacity using the borrowing power calculator on our site, which applies the current serviceability buffer.
The cost of a home loan is not limited to the interest rate. Upfront fees, ongoing account fees, LMI, and the structure you choose all affect what you pay over time.
