Your buyer evidence guide
Understand the home before the offer.
The useful records, what they mean, and the questions they leave open. Start here, then explore the evidence below.
How much price evidence fits
18 sales in the wider suburb/type pool
The wider pool is not a set of identical homes. Bedroom count, condition and location within the suburb affect comparability.
Published auction evidence · model trained through 2026-09-15The strata scheme
SP106632 · 306 lots
Scheme size provides context. It does not tell us the current levies, finances or condition of the building.
NSW strata register · registered 2023What deserves a closer look
- first tracked by our radar (the portal doesn't publish its list date)
These are recorded events, not evidence of the seller's motivation.
What we still cannot tell you
- No settled-sale history is available in this page's records. This does not mean the home has never sold.
- Direct price support is limited. Read the comparable sales and the estimate's uncertainty together.
- Public records and an automated estimate cannot establish whether the home is defect-free, what the contract contains, or why the owner is selling.
Questions to take to the inspection
Use these with the agent and your independent advisers. An answer is something to verify, not a fact we have recorded.
- Which recent sales are most comparable to this home, and how do their size, condition and position differ?
- What repairs, alterations or water issues are documented, and what can an independent inspection verify?
- What do the strata records show about current levies, planned works, meeting decisions and unresolved defects?
The estimate is a model output. The records are evidence. Your inspection and document checks fill the gaps.
Is the asking price plausible?
This is a comparison with the evidence we hold, not a valuation or a recommended offer.

Confidence: Low — based on 18 comparable auction sales (1 of this exact configuration) · model runs ±14% for this configuration · confidence held at Low — under 20 same-configuration sales · priced from this property's own records: building age · thin comparable support for this configuration — read the range as wider, not as a warning
How this estimate was made
- Method: AI PropertyEye tree model · trained through 2026-09-15
- Inputs used for this home: priced from this property's own records: building age
- Comparable support: 18 sales in the wider suburb/type pool; 1 of this exact configuration
- When to be more cautious: This configuration has thin direct comparable support, so its range is deliberately wider.
Suburb risk flags
crime index: 31 — below sydney average · 1 min walk to Castle Hill Metro · ~36 min metro to the CBD · metro ~every 4 min at peak
Where every number comes from
- Fair value: AI PropertyEye tree model 2026-09-02-v7-price-model-v6-full-grid, trained through 2026-09-15 — trained on 169,861 published auction sales; priced per address where this home's own records reach the model (see "How this estimate was made"), otherwise at configuration level (suburb × type × beds), not an appraisal of this exact home
- Evidence trail: tracked by our radar from portal listings, web-archive checks and published auction results — each entry dated
- Risk flags: suburb-level overlays (BOCSAR crime, flood/bushfire intel, aircraft bands, GTFS transit) — NOT a per-parcel assessment
What changed recently?
- 10 Sept 2026 first tracked by our radar (the portal doesn't publish its list date)
- 16 Oct 2026 on market 35+ days — first tracked by us, a lower bound
What to inspect before you offer
- Condition, aspect, renovation and the contract — these can materially change price, and the estimate cannot see them.
- The strata scheme: registration is recorded in 2023 and has 306 lots; ask for the strata report, planned works and levies.
- Building condition: public records cannot establish that a building is defect-free; inspect independently.
These are due-diligence prompts, not a verdict on this property.
⏱ Days on market — this campaign
35 days since our daily sweep first saw this listing.
The portal's own campaign may have started slightly earlier than our first sighting. Longer campaigns tend to mean more negotiating room — the board's "Longest listed" sort exists for exactly that reason.
Rent evidence — asking vs transacted, Castle Hill · postcode 2154
$664–$720/wk is what 1-bed units in 2154 actually transact for (middle half of 34 bonds lodged, Q2 2026 · median $700/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.

The 2 listings above are on the market now: same unit category, within 1 bedroom of 1, asking within 20% of this one, in Castle Hill or a suburb whose centre is within 3 km — ordered by how close the asking price is. That is the whole rule: a filter, not a recommendation, and nothing here judges which home is better.
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 SP106632 registered 2023 — the building is at least 3 years old · 306 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.
