If the RE markets tank, all areas of SD are going to be affected. It might take longer for it to happen in some areas and some areas will see a smaller reduction but no place is immune. When areas drop, they begin to have more value relative to the holdout areas. A lot of people would rather send their kids to school in a school district that ranks slightly lower than pay the ever increasing difference in price. There is a premium for location and schools but it has an end point. The downward trend is likely to be uneven and choppy.
