Most people calculate property costs like this.
Rent minus mortgage. Done.
That is not how property ownership actually works.
Here is the real number on a $700,000 property.
20% deposit: $140,000 out of pocket.
Loan: $560,000.
Weekly rent (conservative): $500.
Weekly interest on the loan: $668.
Before you have paid a single ownership cost, you are already $168 a week out of pocket.
Now add the costs most people forget about.
Council rates: $35 a week.
Water.
Property management.
Insurance.
Maintenance.
A broken dishwasher. A loose tap. A toilet leak. These are not optional. They are inevitable.
Total additional ownership costs: $125 a week.
True weekly cost of holding this property: $293.
Not $168. $293.
This is why we obsess over the rental income number before we recommend any deal to a client.
The higher the weekly rent, the smaller that gap.
And in today’s environment, closing that gap is the difference between a portfolio that scales and one that drains you.
Rent minus mortgage is not analysis. It is a guess.
Know the real number before you buy.
📊 The investors who get caught off guard are not the ones who cannot afford the mortgage. They are the ones who never accounted for the $125 a week in costs sitting underneath it.
🧠 Remember, borrowing capacity is finite. Every purchase either protects or erodes your next move. Buying a property that costs $293 a week to hold without adequate income is a slow leak that stops your portfolio before it starts.
