Buying your first home? Start here.
I'll walk you through it the same way I walk clients through it, and the numbers come last, when they'll actually make sense.

What the bank actually cares about
At the end of the day there are two questions: do you have the money, and can you afford the loan?
Do you have the deposit, and the costs on top?
Can you afford it, the way the bank measures it?
You can have all the deposit in the world, but without the income to service the loan, it doesn't matter.
Some buyers are deposit-limited. Some are servicing-limited. Some are both. The whole game is working out which part is actually stopping you, then attacking that.
Tap the one that sounds most like you. I'll point you at the right first step at the end.

Right, let's start with the deposit.
The deposit equation, and where LMI comes in
LMI usually isn't paid in cash upfront, and Part 3 is about the ways to avoid it entirely.
● The threshold effect: at this price, first home buyers in most states pay reduced or even zero duty. Go over your state's threshold and the full amount snaps back. Same property, same 5% gap, very different cash needed.
Your turn: put your own numbers in.

The reason I explained LMI first is that it makes sense of all of this. Each of these pathways is really someone stepping in to carry that risk for you, so the LMI cost, or the 20% rule, stops being your problem.
Worked example: Queensland
Eligibility, residency rules and price caps apply, and every state draws its own lines. Figures verified July 2026.
Some lenders waive LMI entirely for certain professions: doctors, nurses, allied health, and some legal and accounting roles, letting you borrow up to 90 to 95% with no LMI and no government scheme needed.
Why? The lender's own data says these borrowers are lower risk, so they carry the risk themselves. It's the same LMI logic, just with the lender stepping in instead of the government.
Who may be eligible
A family member offers part of their own property's equity as extra security. That can take your LVR under 80% with little or no cash deposit, so LMI never enters the picture.
A guarantor helps when you don't have the money. It doesn't help if you can't afford the loan.
How it works, and the risk
So the deposit can be solved. But notice what none of these fix.
With one partial exception, Help to Buy, every pathway above answers the money question. None of them fully answer whether you can afford the loan. That's the second gate, and it's where we go next.
Can you afford the loan, as the bank measures it?
No number shown on purpose. Yours depends on your circumstances.
The real question in a strategy session: which problem are we attacking, the servicing problem or the deposit problem?
There are more, and some are personal. That's a conversation, not a webpage.
This gate is personal. No calculator can be the whole answer. The easiest way to get your answer is a strategy session, where we run this exact exercise on your numbers.

You now know the mechanics.
You've just covered the same ground I cover in a real strategy session. The session is where it gets personal. About an hour together, with your actual income, debts and deposit on the table.
We work out which gate is holding you back, list every lever, price each one in borrowing capacity dollars, and you choose which to pull. You leave with a roadmap and homework, not a sales close.
It starts with a quick chat so we can make sure a session is worth your time.
