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.

Planning & zoning — R2 Low Density Residential
Houses and dual occupancies. A protected low-rise street — little chance of towers next door.
Height limit 9m (≈ 2 storeys) — the current legal ceiling for new building at this point under the LEP. Any proposal above it needs a variation or a rezoning — the kind of change the fast-track pipeline tracks.
Zone R2 (Low Density Residential) under the THE HILLS SHIRE LEP, from the NSW ePlanning layers at this address's geocoded point — a guide, not a parcel-level legal check. Confirm the exact lot at the NSW Planning Portal.
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 SP67402 registered 2002 — the building is at least 24 years old · 17 lots in the scheme.
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.
School catchments
Excelsior PS (primary) · Crestwood HS (secondary)
3 primary schools within 2 km · ICSEA ~1139 — the socio-educational advantage of the school community (My School, national average ~1000): a demographic measure, never a results or quality score.
NSW DoE intake zones at this address's geocoded point — tighter than a suburb-level guess, but geocodes carry a few metres of error and boundaries change with reviews. Verify the exact address at School Finder. Intake zones cover government schools only.
