I agree, landlords get away with murder in this country. They can let houses to any shower of anti social gurriers they like, then just pocket the rent and walk away leaving the neighbours to cope with the problems. We had a real problem with a rented house on our road, loud parties, cars parked all over the place etc. The landlord did nothing about it until the guards kicked the door in one night and raided the place for drugs and charged the residents . They were evicted pretty damn quick after that, but it shouldn't have been left so long.
Landlords should be liable to be fined if they have tennants causing persistent problems for the neighbours. Its far too easy for them to just sit back and do absolutely nothing.
