Hi Stephanie - the biggest variable is how much you want to spend and what is affordable to you. We sold in Orange County (coastal) for years and it is a great area for appreciation. Some other areas in Northern Cal - Marin, bay area, etc...are also fantastic. Biggest factors are your goals in buying in any place, are you going to live there or is this an investment property, and how much to spend. Hope this helps. Cheers!
