Houses in the 2300 block of Centre Avenue in the Hill District photographed on Aug 8. The third home from the left, 2303 Centre Ave, is a city-owned vacant property in which the roof in the back has partially collapsed, leading to falling bricks and other issues, said Sandra Mitchell, who lives next door. A would-be buyer applied to purchase 2303 Centre from the city in 2017, but it remains in city hands, according to public records. (Andrew Rush/Post-Gazette)
