The Number Most Investors Never Calculate
Before you look at a single suburb, you need to know this figure.
When most investors access equity, they focus on what they can use.
The more useful question is what they should keep.
There is a number that sits underneath every purchase decision that most people never calculate. It is not your borrowing capacity. It is not your deposit amount. It is the minimum balance that keeps your life working normally if something goes wrong after settlement.
I call it the net-zero position.
How it works in practice
A client accesses $200,000 of usable equity. The default instinct is to deploy as much of that as possible into the transaction. More equity in the deal means less debt, better leverage, stronger position on paper.
But that calculation ignores what happens when something unordinary occurs. The tenant gives notice. The hot water system fails. A rate movement tightens the cash flow in a way the spreadsheet did not model.
So before we look at a single suburb, I ask one question. What is the minimum balance that needs to sit in an offset account for this person to feel no lifestyle pressure regardless of what the property does in the next twelve months.
For some clients that number is $30,000. For others it is $80,000. It depends on income stability, existing commitments, and how much friction they can absorb without it affecting their daily decisions. The number is personal. The principle is not.
