St. Joseph, the husband of Mary and earthly Father of Jesus Christ, is honored as the patron saint of married couples, families, carpenters and workingmen. March 19, his feast day, is especially celebrated by people of Italian and Polish descent.
Over the years, the tradition arose of St. Joseph having a special power in real estate transactions. European nuns buried a medal with his likeness on property they hoped to aquire for convents. Gradually the medals were replaced with statues and the focus changed from buying to selling. The statue is buried upside down in the front yard with the feet pointing to heaven. It may face towards the home (or towards the street if you want your neighbor's home to sell!) The location of the statue can vary: by the "For Sale" sign, in a flower pot (popular for condo owners), etc.. As long as you can find it once the home has sold. After the home has sold, the statue should be removed from the ground and given a place of honor in your new home.
