How to Use This Site
Model Mortgages is a reference library explaining how lending decisions are made in Australia.
You do not need to read everything.
Start where your situation feels closest.
Move across sections only as needed.
This site explains:
How income is assessed
How borrowing capacity is calculated
How existing debt affects outcomes
How property risk is treated
How sequencing and structure shape long-term results
Why outcomes change over time
Execution and personal advice are handled separately.
What This Site Is — and Is Not
Model Mortgages provides general information only.
It does not:
Provide personal advice
Recommend lenders or products
Replace professional guidance
It exists to make lending decisions make sense before you encounter them.
Prefer to Talk It Through?
Some people use this site to understand the system.
Others prefer to speak with a broker once they understand their constraints.
