Industrial land is not as valuable as an infill residential parcel.

Other than that, the city is largely residential with many jobs focused around providing for those residential needs such as the service industry sector, home repair, construction, etc.

Quote from @Mohan Sadashivaiah: I would like to know if Data analysis in needed in Real Estate industry.

I’m already hearing rumblings of the ag industry being blamed for lack of water.

You just can’t successfully operate in the real estate industry unless you master these concepts.  

The industrial buy and hold buyers have virtually dried up in San Diego.  

If the laws are still concerning to you, then buy a commercial property, like an office or industrial property, in your area. 

The first time I was laid off it was traumatic because I my industry and the economy were in the toilet but more importantly, I didn't have enough cash flowing RE, second time.... not nearly as bad, and the third time it was my idea and I haven't lost a minute of sleep about my decision. 

I have 32 leaders from Team Leads, Directorate Leads, to our Senior Leaders all working through their lessons over the last 18 months, weekly one on one engagements with each of them (obviously it doesn't necessarily happen each week due to conflicts etc.).  

Networking is huge, so connect with others in the industry, and look for mentorship programs (there are some great ones out there).
