I own SFD and MFD in Richmond. Like @Jay Hinrichs I've been saying for years that Richmond is a great play. One of the last affordable Bay Area Cities that has a Bart station. And as @Steve Hodgdon mentioned, now there is a Richmond ferry and a building department that wants to see more housing development. On the downside, the city has way to many city programs that landlords pay for: rent board, housing inspection program, business license, fire and safety program, to name the ones I can think of off the top of my head. So when running your numbers make sure that you include the cost of all those things because they really add up.
I know Jay is grabbing up land to develop in Richmond (have you started building on any of those lots Jay?), but there are also good small multi-family deals to be found on the MLS. Yes, there is city rent control in Richmond. There is a domino effect of all these Bay Area cities implementing rent control, I imagine that Vallejo will be up next. So, my vote for what it's worth is to buy in Richmond.
