The rent-or-buy gap

At the census, the typical monthly rent worked out to $1,192 against a typical mortgage repayment of $1,546:

What this gap does and doesn't tell you

The mortgage figure reflects loans and rates as at August 2021, before the 2022–24 rate rises — today's repayment on a new loan would be higher. The rent figure is what tenants were actually paying, not today's asking rents. The useful signal is the shape: where rent and repayments sit close together, buying has historically competed well with renting here; where repayments tower over rent, the market prices in growth.

Your call

Rent covered roughly 77% of the typical repayment here — a middling shape. Owner-occupiers do fine in markets like this; an investor needs a sharper reason to pick it. And be honest about size: 18,317 people is a thin market — fewer sales, fewer buyers when you want out, and longer waits at both ends.
