The numbers, in plain English
To rent in St Clair without housing stress, a household income of about $121,000/year keeps the rent of $700/week at or below 30% of gross income, the standard affordability benchmark. That rent is the official median for a 3-bedroom house, the most common new lease in postcode 2759 (20 bonds lodged). NSW publishes bond data by postcode rather than by suburb, so this is postcode 2759's figure, not St Clair's alone. Check your income →
To buy the median home ($810,000) with a 20% deposit of $162k, repayments at 6.85% over 30 years come to about $4,246/month: comfortable on roughly $170,000/year under the same 30% rule. Saving that deposit at $1,500/month takes about 9.0 years, before stamp duty of $31k ($2k for eligible first home buyers). Run your own loan →
That price is an estimate, and probably too low. No government publishes open sale prices for New South Wales, so we model it from distance, population and income. Checked against real sales, the model runs about 40% under. Treat this figure, and the deposit and repayments built on it, as a rough scale, not a number to plan around. How we're fixing this →
Compared to the rest of New South Wales, St Clair is more expensive to buy than 91% of the state's suburbs (state median $380k) and pricier to rent than 80% (state median $575/week). It sits roughly 40 km from the Sydney CBD as the crow flies.
For investors, the median rent against the median price gives a gross rental yield of about 4.5% before costs. Net yield calculator →
