I agree with your comments and I wouldn't recommend a new teacher to try finding their own accommodation based on the points you made. However, this is the problem with trying to establish 'essential' conditions as opposed to personal preferences. I'm going to stick my neck out on the line and say that all teachers would expect to be paid in full and on time but beyond that things get a little less black & white and what might seem essential to a happy working environment for one person may not be so for another. A case in point would be the recent spat between two regulars over how essential it is to hold a 'proper' working visa.
