“Left leaning landlord” is an oxymoron ;p

Or at least if someone actually held to their principles, they would not remain both for very long ^.

(The concept of a separate ownership class, which is the defining feature of landlordism, is in direct contradiction with leftism, which at the furthest end pushes for the destruction of these sorts of hierarchical class systems, or at the very least attempts to abolish the gatekeeping and hoarding of base necessities like shelter)
