§ 02 — Methodology

A model, not a marketing page.

Every calculation is grounded in the actual serviceability formulas, ATO tax tables and APRA buffers banks use internally — then explained in plain English by an AI that has read every relevant policy paper.

Ask in English. Answer in numbers.

Specialised assistants — one per domain. They run calculations live, cite the formulas, and never recommend a product they earn from. (We don't earn from any.)

I earn $145k, partner $80k. We've saved $180k. Can we afford a $1.1M townhouse in inner-west Sydney, and what would repayments look like?
…and what's our break-even if we wait 6 months?

Yes—comfortably. With $225k combined income and $180k saved, here's the picture:

Borrowing power
$1,284,000
Stamp duty (NSW)
$48,790
Deposit needed (20%)
$220,000
Monthly @ 5.94%
$5,232

You're $40k short on a 20% deposit—you'd pay $18,400 in LMI at 16.4% LVR, or wait ~7 months at current savings rate.
