Detroit — Residential property values climbed 8% last year, marking the fourth straight year of property value growth in Detroit, officials said Thursday. Mayor Mike Duggan said 189 out of 194 neighborhoods saw values rise. The majority — or 111 neighborhoods — saw a 5% to 10% boost. Another 53 neighborhoods saw values go up by 10% to 15%; seven others had values go up by more than 15%. There were 18 neighborhoods that had increases of less than 5%. "It isn't they went up in downtown and Midtown and went down everyplace else," Duggan said during a news conference while referencing a color-coded city map. "This is what a healthy, growing city should look like. It should show property values going up from one end of the city to the other."
