⏱ Days on market — this campaign

118 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, Double Bay · postcode 2028

$1545–$2600/wk is what 3-bed units in 2028 actually transact for (middle half of 14 bonds lodged, Q2 2026 · median $2250/wk — NSW Fair Trading, CC BY).

2019Q1 → 2026Q2: $750 → $1050/wk · +6% over the last 12 months (latest four quarters averaged against the previous four) — quarterly new-tenancy medians for units in 2028, 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 — Double Bay 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):

2023Q3 $1285k (6) · 2024Q3 $1648k (4) · 2024Q4 $1525k (7) · 2025Q2 $1988k (4)

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.

Agencies' own published sales nearby — Double Bay, around 3 beds

Prices as published on the selling agency's own website (their sold pages) — includes private-treaty sales the auction results never see. Only sales the agency chose to publish a figure for appear here.

Similar properties — on the market now

The 6 listings above are on the market now: same unit category, within 1 bedroom of 3, asking within 20% of this one, in Double Bay 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.

Planning & zoning — E1 Local Centre

A retail/commercial hub — shops and services at your door, but busier and noisier.

Zone E1 (Local Centre) under the WOOLLAHRA 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.

Development applications — at & near this address

Development application data © NSW Department of Planning and Environment, used under CC BY 4.0. 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. Verify any application on 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 SP92990 registered 2018 — the building is at least 8 years old · 13 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.

Protected public recreation land within 250 m

Land zoned RE1 under the local environmental plan — reserved for public recreation, which protects it from being built over. The zoning doesn't say what's on it or how usable it is, and this layer doesn't carry park names.

Privately-zoned recreation land (RE2 — typically golf courses or club grounds) within 1000 m. Private land: green outlook, not public open space.
