Problem: Home ownership in Sydney was less common than renting prior to the Second World War but this trend has since reversed. Median house prices have increased by an average of 8.6% per annum since 1970. The median house price in Sydney in March 2014 was $630,000. The primary cause for rising prices is the increasing cost of land which made up 32% of house prices in 1977 compared to 60% in 2002. 31.6% of dwellings in Sydney are rented, 30.4% are owned outright and 34.8% are owned with a mortgage. 11.8% of mortgagees in 2011 had monthly loan repayments of less than $1,000 and 82.9% had monthly repayments of $1,000 or more. 44.9% of renters for the same period had weekly rent of less than $350 whilst 51.7% had weekly rent of $350 or more. The median weekly rent in Sydney is $450.

Problem: Hoping to end their horrendous five-game skid, the Cardinals traveled to McAfee Coliseum to face the Oakland Raiders.  The Raiders came into the game at 0-5, the only winless team in the NFL.  This would be the Cardinals' first game under new offensive coordinator Mike Kruczek, who replaced the fired Keith Rowen in the wake of Arizona's meltdown in the fourth quarter of the game against Chicago. Arizona has visited Oakland only once before.  The Cardinals won 34-31 on an overtime field goal by Bill Gramatica on December 2, 2001.  The Raiders won the last meeting with the Cardinals, 41-20 at Sun Devil Stadium on November 24, 2002. In the first quarter, the Cards string of bad luck continued to haunt them, as Raiders RB ReShard Lee got a 1-yard TD run, while QB Andrew Walter threw a 32-yard TD pass to WR Randy Moss.  In the second quarter, both teams swapped field goals.  Oakland kicker Sebastian Janikowski got a 31-yard field goal, while Arizona kicker Neil Rackers nailed a 29-yard try.  In the third quarter, the Raiders continued to pour on the points, as Janikowski got a 35-yard field goal, while Defensive Tackle Terdell Sands tackles Cardinals RB Marcel Shipp at the goal line for a safety.  The only response Arizona could bring up was Rackers kicking a 45-yard field goal.  He would kick one more in the fourth quarter (38-yarder), but that would be all that the Cardinals could produce as they now dropped six-straight games.
