When I write my market reports, I often provide the average and median sale price of properties.
Those numbers are often different and buyers should understand why:
Average Sales Price:
All sales are added together and divided by the number of sales.
Median Sales Price:
All sales are lined up from lowest to highest, the sale in the middle is the median sales price.
In Real Estate we usually use median figures to describe market statistics because it is not influenced by extreme numbers.
For example, if most of the properties in the area are sold in $500,000 range but one house is sold for 1 million:
AP: (450k+480k+500k+550k+1mln):5= $596k
MP: would be $500k.
Comparing MP to AR, it is clear that the median value is much more realistic interpretations of the housing market.
National Association of REALTORS® provides this definition:
''A mean (average) is calculated by adding up all the values in a distribution and then dividing the sum by the total number of values contained in that distribution. To find a median value, one takes all of the values in the distribution, sorts in ascending order, lines them up and finds the middle value.''
