Suburb risk flags
crime index: 27 — 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 Mona Vale — 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, Mona Vale · postcode 2103
$819–$962/wk is what 2-bed units in 2103 actually transact for (middle half of 20 bonds lodged, Q2 2026 · median $862/wk — NSW Fair Trading, CC BY).
2019Q1 → 2026Q2: $620 → $850/wk · +7% over the last 12 months (latest four quarters averaged against the previous four) — quarterly new-tenancy medians for units in 2103, 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 — Mona Vale units at auction
Too few same-bed sales for a measured growth rate yet. Recent quarterly sold medians (all unit sizes — thin samples move these):
2024Q1 $1400k (5) · 2024Q4 $1200k (5) · 2025Q1 $1192k (4) · 2025Q2 $2330k (3)
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.

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 SP81458 registered 2009 — the building is at least 17 years old · 25 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.
