The SFO 777 flying is the best flying in the system in my opinon. high paying trips and if you dont commute easy to get some of 26-27 hour 3 day asia trips. My rental units in the city are averaging around 3500 a month so not to crazy. (looks like i have a vacancy coming up if you are interested) I would stay away from the east bay...the traffic can be chaos on the bay bridge depending on when you need to be at work or get done. Far less traffic coming across the GGB from marin and sonoma. Further north you go cheaper it gets.
