Located on a quiet cul-de-sac in the established Quarry Oaks neighborhood, with no HOA, 904 Quartz Ct offers a strong investment profile with immediate income and upside potential, just minutes from Austin. This duplex features each side with 3 bedrooms and 2 full bathrooms. Both units offer hard tile flooring in living areas, kitchens, hallways, and baths, with real wood flooring & vinyl planks in all bedrooms-no carpet. Each unit includes ceiling fans in every room, a storage room side B, and spacious private wood-fenced backyards. Unit B includes a covered patio. Unit A has Covered & enclosed patio! Recent updates include a new roof and fresh interior paint in 2025. Unit A is tenant-occupied by a long-term resident who has maintained the unit immaculate, currently renting for $1,275/month, with room to increase rent. Unit B is vacant with projected rent $1,750/month, ideal for investors or owner-occupants. Unit B, half of the garage was converted to a flex room prior to the current owner's purchase. Remaining garage and storage areas provide added functionality. Conveniently located near shopping, grocery stores, employers, and freeways, including Costco and retail corridors, with easy access to Downtown Austin. Duplexes of this quality and location are rare-especially with no HOA and priced below market-making this a strong opportunity for cash flow and long-term value.
