In the Pinehurst Area single family homes and horse farms in the price range of $550,000-$1+M had only 3 sales in the month of September while $0-$549,999 had 69 with the majority of those sales being $175,000-$299,999. So, as you can see what is listed and what is selling has a large diversity. If you are buying and selling it is best to check the type of home and the price range you are working within.
Both numbers are meaningless for a person buying a single home in an area, particularly if they are not buying it for an investment.
Its like the old cliche about the average family being 2.5 children.
The average and the median are useful for comparing eras and areas, but the numbers are dynamic, constantly changing.
Good luck and may God bless
