        Unmortgaging costs half the face value plus 10%. Between deciding
        to unmortgage and money being taken the player will be given the
        opportunity to make deals or sell other properties. If after this
        they do not have enough money, the whole transaction will be aborted,

        [old_kent_road, bow_street]

        The properties should be Property objects.
