8. Current Market Price – $109.1 Million

Although most of the huge mansions on the Bishops Avenue are falling apart and lying in shackles, their prices have been soaring high constantly instead of falling down. The street was once called a Millionaire’s Row, but the prices of the properties in this area have soared so high over the years that an average millionaire cannot afford them. The street has therefore gone ahead to be called the Billionaire’s Row, housing huge mansions and properties that have a current market price of $109.1 million. The prices are projected to rise even more in the future.
