berkeley rent control

[Jin Kim]

One of agents emailed me a deal today. It's a 6 unit property in Berkeley. All 2 bed 1 bath. 4 of them pay $600 per month which is only about 30% of the market rate. Is this deal something we should avoid? This is something we can work it out after purchase? I wonder how difficult it would be to push them at least up to 60% of the current rate.
