the sad part is this is a major play off of what is happening in SF right now. Ive lived here for seven years and the growing tech industry is really changing the face of the city in a lot of different ways. I can personally cite an example, because i got a sixty day eviction notice on my place I've been living at for years because an up and coming wealthy couple bought it and are moving in. Therefore, all tenants rights and such are voided because i live in a building built after 1979. Id like to say fuck you to tracer because not only is the art department hitting the nail on the fuckin head they are pretty up to date on current issues in the environment they find themselves in.
sounds like you know your shit, but have you contact the SF Tenants Union? They're super cool, and know their shit. And they're really helpful, especially because they have a good understanding of what's going on in the city right now. And believe it or not, SF rental laws tend to favor tenants more than landlords.
Im pretty sure they new owners have to move in and live there for a certain amount of time before they try to rent it. Keep your eye on the place, if you see them listing it for rent shortly, you may end up owning that house!!!!
I live here too, it's kinda fucked right now. Best of luck.
