Using Zillow prices within cities is a flawed methodology, because it's sensitive to how city boundaries are drawn, which varies a lot - sometimes city boundaries only include their historic "downtown" core, while other cities include suburbs and even exurbs outside the "urban" area. For an example, compare the boundaries of Boston (https://goo.gl/maps/8DCq5vc4vyMR8BVU8 https://goo.gl/maps/8DCq5vc4vyMR8BVU8) with those of Jacksonville, FL (https://goo.gl/maps/BA3sdH4X7iebiqpV9 https://goo.gl/maps/BA3sdH4X7iebiqpV9). Ideally, you'd prefer to compare housing prices within a fixed commuting time of the job location. This is pretty hard, so an alternative would be to use housing prices within the Metropolitan Statistical Area[1], but that's often too coarse.
