The second house, which is very close to Anthony Morris' is tax free since it is owned by the Watchtower.
Whose living there? I thought that it may have been bought as a place for his sons, who are Bethelites, to stay when they visit their parents as they wouldn't want them associating with the local congregation and put them under pressure for gossip or to make it more convenient for them to visit regularly and not have to live at their parents house and be under their influence.
But, there's another possibility and it goes with my theory that Morris had either injured himself whilst drunk or that he has an illness brought on by too much drinking. Maybe a JW nurse (and family) is staying there to look after him. The cost would be minimal, being a full time worker for the Watchtower.
