Introduction

Hi, I’m Ross McFarlane, welcome to How To Home Loan. This site exists to help you understand how home loans actually work in Australia before you talk to any bank or broker. In the next few minutes, I’ll explain the system, what affects your borrowing power, and what most people get wrong.

What this site covers

This site covers three main things. First, how to calculate your actual borrowing power. Second, government grants and stamp duty concessions across all Australian states. Third, the complete home loan process from decision to settlement.

How banks calculate borrowing power

Banks use a serviceability formula that includes your income, existing debts, living expenses, and interest rate buffers. Credit cards, car loans, and HECS debt all count against you. Banks also use the Household Expenditure Measure to estimate living costs. They then test whether you could still afford repayments if rates increased by 3%.

Government support varies by state

As of 2026, Queensland and Tasmania are offering $30,000 First Home Owner Grants, but only until June 2026. South Australia is the only state with no property value cap on the grant. The state guides on this site break down exactly what is available in each state, what you are eligible for, and how to apply.

Common misconceptions

Pre-approval does not mean you are approved. It is conditional and expires after 90 days. Just because a bank approves you for a certain amount does not mean you should borrow that much. The First Home Owner Grant is not available for established homes in most states.

Conclusion

Everything on this site is free whether you work with a broker or not. Use the borrowing power calculator, check your state grant page, and explore the guides to understand the process.

Calculators built on real bank logic

These calculators use the same serviceability formulas Australian banks apply. Not estimates, not marketing figures.

The Math of Lending

Most first home buyers are surprised to discover how different a bank’s assessment is from their own estimate. This is what actually happens when a lender reviews your application.

APRA Rule

The Serviceability Buffer

Banks do not assess your ability to repay at the current interest rate. They add a minimum 3% buffer on top of the loan rate and test whether you can still afford the repayments at that higher rate.

If the loan rate is 6.2%, the bank assesses your repayments at 9.2%. This is set by APRA and applies across all Australian lenders.

Living Expenses

The HEM Model

Banks use the Household Expenditure Measure (HEM) as a benchmark for living costs, set by location, income level, and household composition.

If your declared living expenses are lower than HEM, most lenders use HEM anyway. Your real spending habits directly affect what you can borrow.

Deposit

LMI and the 20% Threshold

Lenders Mortgage Insurance (LMI) is charged when your deposit is below 20% of the purchase price. It protects the lender, not you, but you pay the premium.

The First Home Guarantee allows eligible buyers to purchase with 5% deposit and no LMI, with the government guaranteeing the remaining 15%.

Debt Assessment

What Counts Against You

Banks include all existing debts: personal loans, car loans, credit cards at the full limit regardless of your balance, and HECS/HELP debt.

A credit card with a $10,000 limit reduces borrowing power even if the balance is zero. HECS debt is assessed as a percentage of gross income.

2026 Update
HECS/HELP debt assessment changed from March 2026. Banks now assess HECS repayments based on updated ATO repayment thresholds. Use the borrowing power calculator to model the current figures. Read the 2026 changes →

First Home Buyer Grants by State and Territory

Grant amounts, eligibility rules, and stamp duty concessions differ significantly across Australian states and territories. The rules also change regularly, so check the current figures for your state before making any decisions.

Each guide covers the current grant amount, property value caps, eligibility rules, how to apply, and how the grant interacts with stamp duty concessions.

Frequently asked questions

How much deposit do I actually need to buy my first home?
The minimum deposit is typically 5% of the purchase price, but at this level you will pay Lenders Mortgage Insurance (LMI) unless you qualify for the First Home Guarantee scheme. A 20% deposit eliminates LMI entirely. You also need stamp duty and other purchase costs on top of your deposit. The deposit and LMI calculator models the costs at different deposit levels.
What is pre-approval and does it guarantee I will get the loan?
Pre-approval is a conditional assessment from a lender indicating how much they would be willing to lend, subject to a satisfactory property valuation and your financial position remaining unchanged. It is not a guaranteed loan offer. Pre-approval typically lasts 90 days and a lender can still decline after pre-approval if the property valuation comes in short.
Why is my borrowing power lower than I expected?
The most common reasons are the APRA serviceability buffer (banks assess repayments at the loan rate plus 3%), existing debts including credit card limits regardless of balance, HECS/HELP debt, and the HEM living expense benchmark. The borrowing power calculator on this site models all of these factors.
What is the First Home Guarantee and who is eligible?
The First Home Guarantee is a federal government scheme that allows eligible first home buyers to purchase with a 5% deposit without paying LMI. The government guarantees the remaining 15% to the lender. Income caps, property price caps, and citizenship requirements apply. The First Home Guarantee page on this site covers the current eligibility rules.
Do I have to pay for anything on this site?
No. Everything on this site is free. The calculators, state and territory grant guides, video course, and written guides are all available without payment or signup. If you later choose to work with a broker on a first home buyer loan, the broker is paid by the lender. There is no upfront fee for that service.
How is HECS/HELP debt factored into a home loan application?
HECS/HELP debt is treated as an ongoing repayment obligation. Banks assess the required annual repayment based on your income relative to the ATO repayment threshold schedule. It reduces the amount you can borrow. The assessment rules changed in March 2026 following updates to the ATO threshold schedule. Use the borrowing power calculator to model the current impact.
