Cap rates in Berkeley CA

[David Murphy]

Hi all. I'm trying to talk to owners of small multi-families in Berkeley, CA, about allowing me to take over properties using master lease options. One piece of important info in generating a future purchase price is of course the cap rate. As you may know, valuing multi-families in Berkeley, Oakland, and San Francisco is a tough game due to the high demand, the rent control, and the very low cap rates. I'm wondering in anyone on the forum knows of a decent resource for info on neighborhood cap rates other than local realtors. 

Let me know if you know. Thanks!
