The big Australian question

Rent or buy?

The honest version: not just the mortgage, but stamp duty, ownership costs, and what the renter could earn investing the difference. See who's actually ahead — and by how much.

better off by renting & investing — though that's close enough to call a draw.

if you buy

Modelled monthly in nominal dollars: home growth 4% / yr, rent growth 3% / yr, investments 7% / yr, ownership costs 1.1% of value / yr, 2.5% selling costs, 6% mortgage. The renter invests the deposit and any monthly saving; the buyer's wealth is home equity net of selling costs. Rent vs buy is hugely sensitive to growth and how long you stay, and this ignores tax, negative gearing and first-home grants. A guide, not advice.
