to be honest i think the biggest contribution to the downfall of neighbourhoods was the huge increase in buy to let properties where landlords bought up a lot of houses and rented them out to anyone and couldnt care less how thier tennants effected a neighbourhood as long as they got the rent paid to cover the mortgage
i think a few people here can probably relate to their once peacefull street been decimated because a landlord put some scummy family into a house to get his mortgage paid
landlords should be held more accountable for their tennants behaviour so that instead of renting to anyone to get the mortgage paid they will stop and think if tehy woudl liek teh person they are renting to living next door to them
