Relocating to Oceanside?

Howdy everyone. I recently received a job offer in Oceanside and wanted to understand a few things before I decided to take it or not.

1. What sort of salary would someone need to live comfortably? I'm a single guy in his late 20s and would be relocating from the Midwest. Having roommates my age would be nice, but also would be open to a studio or 1 bedroom.

2. What is the music scene like? Are there any studios or music production groups around? How are the music venues?

This would be a major change for me, and any insight y'all have is appreciated!
