Bore water quality risk | R1 zoning for dual income | Estate appeal vs. access trade-off | Self-contained wing creates margin The principal risk is the 321ppm bore water, which may require treatment for potable use, adding ongoing filtration costs. The R1 zoning and self-contained wing present a clear commercial logic for short-stay accommodation or multigenerational living, offsetting holding costs and improving total return. The property is best held as a lifestyle income hybrid rather than a pure family residence. The 1.48-acre lot with irrigated gardens, fruit trees, and olive grove at 420m elevation gives this homestead rarity in a tightening Adelaide Hills market. The 324m² stone residence with flexible floorplan and shearer’s shed studio competes on space and character, not proximity. It suits a buyer seeking dual use—occupancy plus rental—or a setup for extended family with separate zones. To test the bore water constraint and the short-stay yield, request a water quality report and a projected rental schedule from the listing agent.
