Thanks for your replies guys. I did answer you on Friday evening but don't know where it vanished too!
It is a residential property murphaph. I am inclined to agree with QED about getting a good long term tenant. We have just invested a lot of money refurbishing the property so I would obviously prefer to have a good long term tenant. He was going to read the tenancy agreement over the weekend and come back to us today, so we'll see talk to him then.
Thanks again.
