What caught my eye were the large number of sales in Gilbert and also Chandler.

Remember that zip codes vary tremendously in size. Some have many more homes than others. That means a large circle may just represent a large zip code, not necessarily that homes are selling well in that zip code.

Note regarding home sales less than $10,000. When I calculate sales and median prices, I discard sales below $10,000. Years ago I assumed they were typographical errors, however, some homes in very inexpensive areas are indeed selling now for under $10,000 so my data will under estimate the number of sales and over estimate the median price per square foot in those very inexpensive zip codes.
