I lived in a rent controlled apartment in SF for a year. What was frustrating was realizing that I was paying significantly more rent than other tenants in similar units.
How did you end up paying more than comp with a rent controlled unit? That doesn’t make much sense.
If the other renters had been there for many years, they'd effectively still be paying the market rate from years earlier. That can be a great deal less than market rate now.
That's why renters in rent-controlled units tend not to move as much - as market rates go up, your rent gets relatively cheaper over time and that's an incentive to stay put.
The rent controlled landlords struggled, and didn't have much, or any, wiggle room for upkeep. (Just look at the Parkmerced saga. The place was a dump, but politics prevented them from fixing it.)
I moved into my rent controlled apartment because it was a good deal; the non-rent-control apartments actually cost more at the time.
