How the Street Score works. Every address on Heydon Street is matched (G-NAF) to its ABS 2021 mesh block and SA1 area. Each block scores 100 when owner-occupiers are above 65%, public housing is 5% or less, and both its median rent and rental yield are at or above the Mosman median; 75 when one of the rent/yield tests passes; 50 when neither does; 25 when only one of the two tenure tests passes; 0 when neither does. The Street Score is the address-weighted average of its blocks — the same street test our research engine applies to every listed property. Suburb medians are as of Sept 2026; tenure is from the 2021 Census. Past performance is not a reliable indicator of future performance. Nothing on this page is personal financial advice.
