A landlord protecting the reputation of tenants could be classfied a conflict of interest- particularly if a group of those tenants being defended turned out to be perpetrators of any kind of act that the landlord was defending their reputation about. Imagine the headlines if the press got hold of a story like that.
Landlords should be landlords- their job is to maintain the property, collect the rent and enforce the tenancy. Tenants complain, perhaps rightly so, about rent rises, but all of the extras that they provide outside of their most basic landlord duties add a layer of cost and that cost will inevitably be passed on!
I wonder how many rent paying tenants would happily see services cut right back in return for a reduction in rent!?
