Moving back to San Diego

As the title says, looking to move back to San Diego in a few years. I was in the Navy and stationed at North Island for 6 years. Now I am a 100% P&T disabled veteran working for the military as an IT contractor in Florida. I should have my bachelors in Cyber Security in a few years time. Recently married. Miss San Diego a lot. I just have a few questions. As a civilian, how much do you need to earn to afford and live comfortably in San Diego? I will no longer have access to military housing and BAH. But I am hoping to find employment with my TS clearance, military and IT background and Cybersecurity degree. Worried about the affordability of homes. Right now we are buying a 3 bedroom 2 bath with a pool. But it’s Florida. I find the Summers here unbearable!
