3 Seaham Court, Upper Coomera QLD 4209

Cul-de-sac position | side access for boat or van | pool with cabana | council-approved annex | Highland Reserve estate | one-family ownership for 18 years The buying case rests on three uncommon configurations: side access, a council-approved annex with granny flat potential, and a pool with cabana in a tightly held cul-de-sac pocket. These features are rare in Upper Coomera and directly serve multi-generational households, investors seeking dual-living income, or families wanting separate workspace. The single-family ownership history and absence of flood, bushfire, or heritage overlays reduce latent risk. Ducted zoned air conditioning and solar panels lower ongoing costs, while the 672m² lot with 64% building coverage leaves usable yard space. This property best suits a buyer who values flexibility over turnkey perfection. The primary risk is the annex requiring separate council approval for independent occupancy, which introduces timing and cost uncertainty. The 2009 build age means some systems may approach renewal cycles, though solar and ducted AC are recent. The rental yield estimate of 4.4% is solid but not exceptional for the area. Opportunity lies in converting the annex to a registered granny flat, which could lift yield toward 5% and increase resale pool to investors. The property should be held medium-term to capture suburb growth and amortise any upgrade costs, or used as a dual-living family home with immediate lifestyle benefit.
