Nancy Trekker urgently wanted to buy a home in August 2007 because her cousin, aunt, brother-in-law, in fact almost a dozen of here relatives bought a home or upgraded in a short span. Normal human behavior dictates to follow what others are doing or rather follow the herd. This is the very reason why there is a steady stream of buyer interest in a sellers market i.e. the urge that every one is buying so I should buy as well. The after effects of this is fewer homes available for sale than buyers. In effect this drives up the market, thereby increasing the property values.
