10 Redan Street, Mosman NSW 2088

10 Redan Street, Mosman | 891m² elevated landholding | architecturally renovated family house | Balmoral-slopes position with water outlooks | strong school catchment access The buying case rests on the combination of a substantial 891m² land parcel with a 402m² designer renovation completed to a high standard, including a Calacatta marble kitchen with Wolf and Sub-Zero appliances, a temperature-controlled wine cellar, and a heated pool and spa. This places the house in a scarce category for Mosman’s Balmoral-slopes pocket, where large elevated blocks with northeastern aspect and water views are limited. The property suits a buyer seeking a move-in-ready family home with strong indoor-outdoor flow, multiple living zones including a loft-style kids’ retreat, and proximity to Mosman High School and Balmoral foreshore. The 2020 sale at $12.5 million provides a known entry point, but the current guide being unstated reduces near-term price confidence. The main risk is the unresolved land size discrepancy reported across sources at 891m², 901m², or 885m², which affects site coverage and pool setback verification. The rental yield estimate of 1.71% is flagged as low accuracy and cannot be relied on from the visible evidence alone. A practical opportunity exists in the dedicated home office and loft rumpus room, which may suit remote workers or multi-generational living, but the feasibility of this use within council overlays needs to be established. The key unresolved question is whether the price guide reflects a premium for the renovation quality or a discount for the land size uncertainty, and confidence cannot be formed until that is clarified.
