In Shanghai, having a south-facing view in your apartment can increase its value by 14%. A view of a famous landmark adds 6% to the value, and if it's south-facing, that's another 4% boost. Dust pollution can lower prices, especially for south-facing views. PM2.5 pollution doesn't affect prices much. People prefer taller buildings with elevators. The inside of the apartment also affects its value, but only when considering all the other apartment features.
