The First Home Buyer Guide for Australia

The honest reality of buying your first home in 2026

Before we get into the detail, let us acknowledge what you probably already know: it is harder than it used to be. Property prices have outpaced wages for over a decade. But 2026 has more genuine help available than almost any year in recent memory.

The 20% deposit threshold that lenders traditionally prefer exists because it is the point at which you own enough of the property that the lender feels adequately protected if things go wrong. Below 20%, you are in what lenders call high loan-to-value ratio territory, and that is where Lenders Mortgage Insurance enters the picture.

Here is the thing: in 2026, there are at least five different ways to buy with less than 20% down, and several of them completely eliminate LMI. This guide walks through every single one.

Can I buy a house with a 5% deposit?

People searching this topic are typically asking: “can I buy a house with a 5 percent deposit”, “minimum deposit to buy a house australia 2026”, “how to buy a house without a 20% deposit”, and “can I use a personal loan for a house deposit”. Here is the answer to all of them.

Yes, and it is now more accessible than it has ever been. The Australian Government’s First Home Guarantee lets eligible buyers purchase with just a 5% deposit and pay no Lenders Mortgage Insurance. From 1 October 2025, this scheme was massively expanded: there are no income caps, no annual place limits, and the property price caps were lifted significantly across every capital city.

Here is what that means in real numbers. If you want to buy a $700,000 property, under the standard rules you would need $140,000 saved to avoid LMI. With the First Home Guarantee, you only need $35,000 and you still pay no LMI. That can bring your purchase forward by several years.

What is LMI and what does it actually cost?

People searching this topic are typically asking: “what is lenders mortgage insurance”, “how much is LMI on an 800k house”, and “how to avoid LMI australia”. This section answers all three.

Lenders Mortgage Insurance is one of the most misunderstood costs in property. The most important thing to know upfront: it protects the lender, not you. You pay it. They benefit from it.

When you borrow more than 80% of a property’s value, the lender takes on extra risk. LMI is their insurance policy against that risk. If you default and the property sells for less than you owe, the insurer pays the difference to the lender. You still owe the debt to the insurer.

LMI is calculated as a percentage of your loan amount and is influenced by how much you borrow relative to the property value. The closer you are to 95%, the higher the premium.

Estimates based on indicative Helia and Genworth rates at 95% LVR. Actual LMI varies by lender. Your broker will confirm exact figures.

On an $800,000 property with a 5% deposit, you are looking at $28,000 to $38,000 in LMI. That premium is typically added to your loan and accumulates interest over the life of the loan, so the real cost over 30 years is considerably higher than the upfront number.

How to buy without paying LMI

There are five ways to purchase a home without paying LMI. Some require a government Scheme, some require family support, and some require buying within a particular price point or profession.

How does a guarantor loan work?

People searching this topic are typically asking: “how does a guarantor loan work australia”, “can parents guarantee my home loan”, and “guarantor loan risks australia”.

A guarantor loan is one of the most powerful tools available to first home buyers with supportive family, particularly parents who own their home. It is also one of the most misunderstood, because many people assume the guarantor is handing over cash. They are not.

Here is exactly how it works. Your parents (or another close family member) agree to use a portion of the equity in their own property as security for your loan. The lender takes a limited guarantee over that equity, typically enough to cover the gap between your deposit and 20% of your purchase price. You receive a loan for the full amount without triggering LMI. No cash changes hands between you and your parents.

A worked example

Purchase price: $700,000. Your deposit: $35,000 (5%). The shortfall to 20% is $105,000. Your parents provide a limited guarantee using $105,000 of equity in their property. Your loan is $665,000 with no LMI payable. You save approximately $20,000 to $28,000 in LMI costs.

What the guarantor needs to understand

The guarantor’s own borrowing capacity may be affected while the guarantee is in place, as lenders treat the guaranteed amount as a contingent liability. Once you have paid down your loan enough to sit below 80% of your property value, you can apply to release the guarantee. Most buyers achieve this within three to seven years.

If you default and the property sells for less than you owe, the lender can call on the guarantee. This could require your parents to sell their property to cover the shortfall. This is rare in practice, but it is a real legal risk. Both parties should get independent advice before proceeding. A good broker will insist on it.

Every government scheme you can claim in 2026

People searching this topic are typically asking: “first home guarantee scheme participating lenders”, “how does the help to buy scheme work”, “first home buyers grant criteria australia”, and “fhss scheme withdrawal timeline”.

Here is something most websites will not tell you about government schemes: they are genuinely valuable, but they are also genuinely complicated. Eligibility rules differ per Scheme, property type rules differ, and applying for one can affect eligibility for another if you do not sequence them correctly.

1. The First Home Guarantee

The government guarantees up to 15% of your property value, allowing you to buy with a 5% deposit and no LMI. This is not a cash grant. You borrow the full amount and make every repayment yourself. From October 2025, there are no income caps, no place limits, and higher property price caps across every city.

2. Help to Buy

Launched 5 December 2025. The government buys a share of your home alongside you, contributing up to 40% on new builds and 30% on established homes. You need only a 2% deposit and no LMI. Your loan is significantly smaller as a result.

The trade-off: the government owns that share. When you sell, you repay the government’s portion plus its share of any capital growth. Income caps apply: $90,000 for singles, $120,000 for couples.

3. First Home Owner Grant (FHOG)

A cash payment from your state or territory government when you buy or build a new home. The amount and eligibility rules vary significantly by state. In most states, the grant only applies to new homes, not established properties.

Stamp duty exemptions by state in 2026

People searching this topic are typically asking: “stamp duty exemption threshold NSW 2026”, “stamp duty exemption VIC first home buyer”, and “stamp duty exemption QLD 2026”.

Stamp duty is often the second biggest upfront cost after the deposit itself. On a $700,000 home it can run to $26,000 or more depending on the state. The good news is that every state now offers some form of exemption or concession for first home buyers.

Thresholds are subject to change. Always verify current figures with your state revenue office or broker before exchanging contracts.

The First Home Super Saver scheme (FHSS)

The First Home Super Saver scheme is one of the most tax-effective ways to build a deposit, and most Australians have either never heard of it or found it too complicated to act on. Here is how it actually works.

You make voluntary contributions into your superannuation fund. These contributions are taxed at just 15%, which is significantly lower than most people’s income tax rate. When you are ready to buy, you apply to the ATO to withdraw those contributions (plus deemed earnings) to use as your deposit. The withdrawn amount also receives a 30% tax offset.

The FHSS withdrawal timeline

This is where most people get caught out. The FHSS does not release money instantly. Here is the realistic sequence once you find a property:

Hidden costs most first home buyers miss

People searching this topic are typically asking: “hidden upfront costs of buying a house australia”, “what costs should I budget for when buying my first home”, and “what is stamp duty and do I have to pay it”.

Beyond your deposit, most buyers are surprised by how many additional costs come up between signing and settlement. Here is every one worth budgeting for before you start looking.

The step-by-step buying process

Most buyers try to navigate this process backwards. They find a property they love and then scramble to sort out their finances. That is how people overpay, miss out, or end up with the wrong loan. The correct sequence is this:

Pre-approval delays and what to do if you miss a property

People searching this topic are typically asking: “how long does conditional pre approval take”, “pre approval delays losing property”, and “what happens if you exceed your budget at auction”.

One of the most painful experiences in property is finding a home you love, making an offer, and then watching the deal fall apart while your lender processes paperwork. This section is about protecting yourself from that outcome.

How long does pre-approval actually take?

With a clean, straightforward application (stable employment, clear credit, standard income), conditional pre-approval takes 3 to 5 business days at most lenders. Where it blows out to 10 to 20 or more days is when your situation is more complex: self-employment, multiple income streams, credit file issues, or incomplete documentation submitted at lodgement.

A broker who has experience with your situation will know which lenders process faster and will submit your application with everything needed to avoid back-and-forth delays.

What happens if you go over budget at auction?

If you bid beyond your pre-approved amount and win at auction, you are unconditionally committed to purchasing that property. There is no cooling-off period. If your lender will not fund the shortfall, you risk losing your deposit and being sued for the difference between your bid and what the property eventually sells for.

Pre-approval expiry

Most lenders issue conditional approvals valid for 90 days. If you have not found a property within that window, you will need to reapply. In most cases this is straightforward, but it does mean another credit check. Multiple hard credit enquiries close together can affect your credit score. A good broker staggers applications to avoid unnecessary enquiries.
