Go figure ~ it’s all in the numbers!
News about home sales and prices is everywhere – from newspapers to television to radio. That means home buyers regularly come across words such as average, mean and median.
    It can be confusing and they look to REALTORS® to decipher the sometimes complex language of real estate.


Here are some explanations to help you

  • Mean: is an average that is arrived at by taking a range of home prices and dividing them by the number of units sold. If 12 homes sell in a price range from $220,000 to $690,000, the mean average price is determined by adding all of the sales prices and then dividing by 12.
  • Median: is the middle value. If 12 homes sell in a price range from $220,000 to $690,000, the median price is determined by arranging the sales prices from the lowest to highest. The media is the number in the middle.

    For many decades, the mean and median average were standard industry measures for recording sales activity.
    But these measures were not always accurate. In a neighborhood where 11 homes sell in the range of $650,000 to $850,000, and one home sells for $1.3 million, the average or mean will be significantly skewed.


The Housing Price Index (HPI)
For accuracy, the Greater Vancouver and Fraser Valley Real Estate Boards developed the HPI, a tool to measure market activity.
    The HPI is a measure of price change, for a set time period, for residential properties. It provides the most reliable information on housing price trends.
    It’s modeled on the Consumer Price Index (CPI), which measures the rate of price change for a basket of goods and services including food, clothing, shelter, and transportation.
    But instead of measuring goods and services, the HPI measures the change in the price of housing features such as lot size, number of rooms, age of the home and neighborhood.
    The HPI tracks movement of mid-range priced homes and excludes extremely high and low priced properties.
