105 Stephen Street, Blacktown NSW 2148

North Blacktown | 740sqm rectangular block | granny flat potential (STCA) | 5.6 energy score above state average | quiet street with no overlays The property’s primary buying case rests on its unusually large, rectangular 740sqm block in a quiet North Blacktown pocket with no bushfire, flood, or heritage constraints, which directly enables a granny flat development subject to council approval. This configuration is competitively rare in this suburb and positions the buyer to capture dual-income potential from a single holding. The 5.6 energy efficiency score, above the state average of 4.3, reduces ongoing utility costs and improves long-term holding economics, while the high ceilings and original floorboards offer a solid structural base for cosmetic upgrades. The property best suits an investor or owner-occupier willing to add value through a secondary dwelling or renovation, rather than a buyer seeking a turnkey home. The key risk is the original bathroom and kitchen, which will require near-term capital expenditure to achieve premium rental or resale pricing; the recent rent of $650/week likely reflects this dated condition. The 28% site coverage leaves substantial undeveloped yard area, and the 17.59m frontage supports a separate driveway for a granny flat, though council approval timelines and costs must be factored into the return calculation. The property should be held for at least five years to capture the suburb’s 9.4% growth trajectory and the uplift from any approved secondary dwelling, with a renovation of the main house considered once the granny flat is tenanted.
