First, Great thread OP. I'm originally from DC and hated LA until I moved to the South Bay after living in The Valley for 10 years.
Bro. Let me help you. I've got friends that live on the Westside and in the Valley. They all want places to live, but everybody wants the 'luxury' of the Westside. I recommend Torrance and Redondo Beach all day, but I'm usually ignored by them. So, I give my sage advice to you. I'm walking distance from the South Bay Galleria. I live in a very spacious 2BR/2BA apt. I pay about 200.00 less than you. No crime. No grime. I can be at the beach in 10 minutes driving. You get the best of the beachside communities, and the best of yuppie living with commerce all around you and families (it's a family area) to keep you grounded. Diverse people. Access to everything.
I even made a promo video about the apartments in my area. Just move away from the beach. Trust me, you'll be really glad that you did.
Also, regarding the utilities and appliances: yes, you'll often need to have your own fridge, but regarding AC, you really don't need it in the South Bay. Sure it gets hot, but the breeze and a good fan will get you through most of the dog days of summer here. I lived in North Hollywood and during the summer, I thought I would actually die w/o AC. I don't mean that in exaggeration. Utility bills in other parts of Los Angeles will make you cry. The south bay, ie, Redondo/Manhattan Beach/Torrance/Hawthorne/Inglewood/Carson....are great.
learn to love your side streets and your alternate routes. I worked in Santa Monica for years. Coming from the valley, my commute in the morning was an hour and a half. Going home? Sometimes 2 hours easy. In the South Bay? There are so many ways to get home regardless of how the 405 South moves, that traffic is rarely a problem. I used to grovel to the traffic gods, too. Now it takes me about an hour to get to work in HEAVY traffic if i choose to stay on the 405N. Sepulveda is your friend. You'll often wave to the people sitting still on the highway as you roll right past. Get comfortable with alts and definitely learn the times of day to best move. If you work at 9am, there are golden times to leave that will save you sitting in traffic for no good reason. Where (geographically) is your work?
Wanted to leave this entire chunk intact because it's funny. And true.
I'm a family man now, and an old guy, so I'm no fun. That said, my advice is to avoid making friends with 'industry people'. Absurd, I know, considering where you are. Also, that's a pretty broad rule, which is easily full of holes. However, because you're in South Bay where the jobs of working people are a little more removed from entertainment, you'll find that it's easier to meet people to talk about stuff that isn't based on "what can you do for me" networking.
Wanted to leave this chunk intact, too. I hated this place for years, but once I went back home to visit, I realized that that deep down, I kinda love it. Everything that you listed is AWESOME, and so many people don't take advantage of. You're no more than 3 hours away in every direction from a diversity of climates and things to do. You can go skiing and to the beach in the same day if you plan it right. It's pretty damned amazing.
Before I got married and became a family man, I totally enjoyed many of the places that you named. I encourage you to get out of your car and strike up random conversations with strangers doing things that you already love to do. You'll find that making new friends through genuine experiences can make a real difference.
Best of luck, man. Glad to have read your post.
EDIT: One more thing. The new Metro to the beach? Use it. Outside of just being incredibly convenient, the Metro takes you outside of your personal rolling box, and forces you to see the world around you with fresh eyes. When I used to be into street photography, one of my greatest joys was just walking about 'being' in the world around me. Talk to everybody. Walk on Hollywood and Highland and actually talk to somebody. Everybody's got a story. It's not quite as sexy as New York, but Los Angeles is really quite beautiful. Warts and all.
