It does depend what information you have been given before you view. The length of the tenancy is important to know and, assuming that it will be a short assured tenancy of 6 months, ongoing after that, what then notice period is on either side. Also, are there any hidden extras to pay. Does Council Tax have to be paid by you, and if so, how much is it? Does it have a garden and, if so, do you have to keep it tidy etc (what about a lawn mower?) Is there a phone line and if so, is it connected or will you have to pay the connection charge. All fairly basic questions but don't hesitate to ask anything you are not sure of for better to get things sorted out at the beginning. Good luck!
