The cap rate is low in the single digits.

If you are making low-ball offers I often give a verbal offer to the listing agent to see if it is even worth our time to write it up (It takes me up to an hour per offer to prepare and finalize an offer with digital signatures).  4.

I don't think the markets that fluctuate double digit percentages every year make for very good investments as there is always the risk of a massive drop off at any time.

One way to get a better understanding of the expected cash flow per unit for multiplexes in the Bay Area is to analyze a few deals that are available on LoopNet or other digital sources of multi-familly property listings.  

Couple hundred bucks a door monthly cash flow, double digit ROI, and yes the prices appreciate and you build equity.

I was talking with someone yesterday, who is worth well into the nine digits.  

Double digit net caps are to be had , its all about your team and knowledgeAll the best 

ROI is always double digits, but with every investment you need to do your homework.
