The Property Brief — what the evidence shows. You draw the conclusion.

NO CONFIDENT READ
The model has no confident read on this property: its comparable pool disagrees with the advertised figure by more than 40%, and on our sold-validation set the advertised guide — not the model — predicted the sale in these cases. The comparable pool is likely describing different stock than what is being sold.

Where every number comes from
  • Comps: published Domain auction results for Castle Hill — suburb × configuration matches, not hyper-matched to this address
  • 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

⏱ Days on market — this campaign

1 day 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

$788–$885/wk is what 2-bed units in 2154 actually transact for (middle half of 103 bonds lodged, Q2 2026 · median $820/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.
