When we say suburban area, this is the area that is only a part of the city or a region that is distant from the city but not to the point that it becomes rural. So for John, the best way for him to save up in order to acquire a place to stay in the suburbs is to move first to the suburbs and rent a home for a year. This would give John enough time to decide whether he would like the suburban living and to look for a perfect location for his house.
