At worst, youre partially right. Maybe they’d go up 10K, but certainly not 25K. That’s just not how markets work. It’s the same argument as saying UBI will increase prices - yes, it will, but not by more than or as much as the UBI is. If everybody else sells their home at $25K more, you can sell yours in a month by going down to $15K more than before.
Yeah, that’s the real solution. We have to ban any one entity owning more than 2-3 residential properties. The $25K is simply a decent stop gap until we can actually make that law happen, because our capitalist overlords would never allow it.
