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 Mosman — 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
103 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, Mosman · postcode 2088
$1900–$2700/wk is what 4-bed houses in 2088 actually transact for (middle half of 65 bonds lodged, last 12 mo · median $2250/wk — NSW Fair Trading, CC BY).
2019Q1 → 2026Q2: $1362 → $2100/wk · -1% over the last 12 months (latest four quarters averaged against the previous four) — quarterly new-tenancy medians for houses in 2088, 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.
Development potential — how Mosman Municipal Council treats the work you might do

↩ Withdrawn from auction — what happens next
Withdrawn from auction isn't the end of a sale — of withdrawn Sydney homes that went on to sell, half sold within 65 days.
63% sold within three months of the scheduled auction.
1,547 withdrawn-then-sold homes across Sydney. We don't publish a price figure for withdrawn homes: the measured gap is too unstable to stand behind, and a number we can't defend is worse than none. Based on withdrawn homes that later sold. Homes that never sold aren't in the figure — withdrawal sometimes means a private deal was already done, and sometimes means the listing simply ended.

Settled-sale records from the NSW Valuer General's Property Sales Information.

Planning & zoning — C4 Environmental Living
Low-impact rural-residential in a sensitive setting — tight controls.
Registered lots in Mosman run 250–960 m² (middle 80% of 103 registered parcels). This one is 512 m² — inside that range.
Whether a block this size can be subdivided or redeveloped is a separate question: minimum lot size, setbacks and the council's DCP controls decide it, and this page doesn't check them. One point per registered parcel, so a tower's parent lot counts once — not once per unit. Confirm the parcel and its controls with the council before you inspect.
Zone C4 (Environmental Living) under the MOSMAN LEP, as recorded against this property in the NSW Valuer General's valuation record — a guide, not a parcel-level legal check. Confirm the exact lot at the NSW Planning Portal.

Where these applications come unstuck
The refusal rate above says how strict the council is. This says which part of a plan is exposed — measured across all 192,284 NSW development applications, not just this council. Each is an association: plenty of applications carrying these elements are approved, and nothing here is a verdict on a proposal you haven't made yet.
- Alterations & additions — a new vehicle crossing cut into the front boundary (refused 7.27% vs 2.59% for this kind of work generally — 2.8×, on 220 applications); excavation or a new lower level (refused 6.71% vs 2.54% for this kind of work generally — 2.64×, on 611 applications)
- Off-street parking — a new vehicle crossing cut into the front boundary (refused 8.45% vs 2.42% for this kind of work generally — 3.49×, on 284 applications)
- Pool, deck or fence — excavation or a new lower level (refused 6.22% vs 1.61% for this kind of work generally — 3.88×, on 659 applications); full demolition and rebuild (refused 4.97% vs 1.6% for this kind of work generally — 3.12×, on 965 applications)
- Knock down & rebuild — excavation or a new lower level (refused 25.78% vs 9.36% for this kind of work generally — 2.75×, on 256 applications); full demolition and rebuild (refused 19.91% vs 10.46% for this kind of work generally — 1.9×, on 221 applications)
Determinations lodged on the NSW Planning Portal up to Nov 2023 — the published dataset stops there, so this is a record of how the council has behaved, not a forecast and not a statement about any particular application. Rates cover development applications only; modifications and reviews of an earlier decision are excluded. A rate is shown only where at least 30 applications were decided — below that the counts are given instead, because a percentage from a handful of decisions is not a fact about a council. "Approved with conditions" is a consent, not a refusal, and is never counted as one.

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.
