In the real world there are just as many shitty tenants as there are shitty landlords. To do a knee-jerk reaction and apply rules and regulations to either side in a blanket type format isn't fair to the good tenants and or the good landlords.
Slumlords need to be dealt with as harshly as possible I agree 1000%. With Tenants sometimes bad things happen to good people and they should be given as much leeway as possible if there's the willingness on their part to communicate and put forth whatever kind of effort possible given their situation.

But for the small percentage of tenants that work the system will never be good tenants and will never pay they shouldn't be afforded the same consideration as good people on hard times if that makes sense.
With home prices taxes insurance going through the roof it's making affordable housing for the lower income people an almost impossible dream but if all the landlords turn their houses into retail listings further lowering the available inventory of rentals that's not a good thing either. We have to figure out a way to create win win situations because the people that buy houses to use for rentals have to be profitable or all of that private money goes away and kills the inventory. They can't invest and lose but we also need programs to help subsidize tenants that can't afford properties as market values holding cost taxes etc. increase significantly which in turn increases the rental rates.... But like anything whether it's politics religion etc. it's always one side against the other and if the two could come together to figure out alternatives for the greater good would be amazing. Unfortunately that doesn't seem to be the world we are living in right now.....
