The main issue is that the contract specifically says no pets and no sub letting.
He did not advise us of either - we just know from the amount of complaints and the fact that each time agents have visited people have been residing on the premises. Do we need to collect witness statements? is that sufficient or will he have to admit it?
The commercial use - he has no licence for it? He also has increased the bills considerably which we have had to pay for. Is it therefore worth claiming now or will the court ask why we have mentioned this so late?
