Where every number comes from
- Fair value: AI PropertyEye price model 2026-08-11-v5 — trained on 146,492 published auction sales; configuration-level (suburb × type × beds), not an appraisal of this exact home
- Comps: published Domain auction results for Castle Hill — suburb × configuration matches, not hyper-matched to this address
- Risk flags: suburb-level overlays (BOCSAR crime, flood/bushfire intel, aircraft bands, GTFS transit) — NOT a per-parcel assessment
Rent evidence — asking vs transacted, Castle Hill · postcode 2154
$800–$1100/wk is what 3-bed units in 2154 actually transact for (middle half of 13 bonds lodged, Q2 2026 · median $975/wk — NSW Fair Trading, CC BY).
2019Q1 → 2026Q2: $490 → $800/wk · +7% over the last 12 months (latest four quarters averaged against the previous four) — quarterly new-tenancy medians for units in 2154, all bedroom counts pooled.
Asking rents are what agents hope for; bond figures are what tenants actually signed at (NSW Fair Trading bond lodgements, CC BY). No yield % is derived here: each rent above is a different grain from this home's price, and a ratio of two grains reads as precision it doesn't have. New-tenancy rents run hotter than sitting rents. Not financial advice.
Growth trend — Castle Hill units at auction
Not enough Castle Hill unit auctions on record to show a trend — this fills in as the archive grows.
Suburb-level, from published auction results. No single building has enough sales for a block-level series, so this is the honest grain; sales-mix shifts move raw medians, and the measured rate (when shown) controls for bed count.

⏭ It passed in — what happens next — the question the listing stops at
Homes in Castle Hill that passed in and later sold went for about 6% less than comparable homes that sold under the hammer.
Half sold within 33 days, 76% within three months.
Like-for-like within bedroom and property-type groups · 85 comparable sales in Castle Hill, sales settled in the last two years. Based on passed-in homes that later sold. Homes that never sold aren't in the figure, so read this as what a sale fetches — not what the home is worth. Passing in is a negotiating position, not a verdict — this is evidence about outcomes, never advice on what to offer.
Construction risk — what no listing tells you
Building Commission NSW / Strata Community Association 2023 Strata Defects Survey: 53% of newly registered strata buildings reported at least one serious defect in common property (39% in the 2021 survey). Defects are common, not exceptional — and new does not mean safe (Opal Tower was under a year old).
Get an independent structural and strata inspection before you commit — the defect base rate makes it the single highest-value dollar in the purchase.
We cannot see inside a building — no one can from public records. This section states base rates and observable adjacency only, and will never call a building safe.
The building — its registered strata scheme
Strata plan SP76430 registered 2006 — the building is at least 20 years old · 104 lots in the scheme (large scheme — expect facilities and higher levies).
Registration is an age floor, not a build date — a converted building is older than its strata plan. Scheme records from the NSW Strata Hub. © State of New South Wales (Spatial Services, a business unit of the Department of Customer Service NSW). For current information go to spatial.nsw.gov.au.
