Suburb risk flags
crime index: 25 — below sydney average
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 Dee Why — 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
Local rents — postcode 2099 units, new tenancies
$820/week median new-tenancy unit rent in 2099 (2026Q2, 312 bonds lodged).
The rent is real (NSW Fair Trading bond lodgements, CC BY) but it pools every bedroom count in the postcode and this is a 3-bed — so we don't derive a yield % from it: a ratio of two different grains reads as precision it doesn't have. New-tenancy rents also run hotter than sitting rents. Not financial advice.
Growth trend — Dee Why units at auction
Measured like-for-like growth ≈ -2.1%/yr — 2-bed sold-price medians across 17 quarters (130 sales).
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 8.5m (≈ 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 NORTHERN BEACHES 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.

Matched at this exact address or within ~150 m of its geocoded point — proximity evidence, not a parcel-level check. Lodged means proposed, not approved or built. Outcome comes from a separate NSW dataset that stops in Nov 2023: applications determined after that, or still undetermined, read “not on record” — which means we don't know, never that it was refused. “Status” is the council's own workflow state and “Determined” on its own does not say which way it went.

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 SP43045 registered 1993 — the building is at least 33 years old · 2 lots in the scheme (small scheme — levies and decisions shared among few owners).
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.
