You have zero notion to what the current profit the landlord is making or if it’s anywhere close to “razor thin”.
Yet you pontificated on all the things the increase could be and took the time to get in a jab by asserting it is most likely the op’s fault because they “voted for those policies” yet you conveniently left out the easiest of them all - greed. It’s not beyond the pale for a landlord, especially a private one, to arbitrarily raise prices just because they can.
But, oh no, it must be taxes and crime and everything else under the sun but couldn’t possibly be simple greed. Must be those razor thin profit margins jumping out to scare that most honorable capitalists like the boogeyman under the bed.
