I assume this (and really any extra mandates for landlords) is going to drive more small/private landlords out of the business, and that won’t necessarily increase housing availability on its own, but will instead be filled by larger corporate landlords that can afford to deal with administrative work required. As I’ve gotten older, I’ve found small landlords to be where you can find the best experience (but also maybe the worst, it’s more variable), having just corporate landlords feels like you’ll always get a shittier place (minimal work done) for market rates.
It’s unfortunately nothing new, but I do think the alternative is a new level of bad.
