Haha Nick, I wouldn't say it's that bad!!
Hollywood has been improving tremendously in the past two decades. Since the building of the Hollywood & Highland center real estate has only gone up and many new luxury condominium developments have started to appear stretching out eastward.
Without looking up statistics, but from my personal observation, I would say that the crime in Hollywood is mainly committed by people from other places i.e Compton etc... and a combination of a thriving night life which unfortunately involves drug trading.
I was actually robbed once at gun point about 4 years ago when coming out from a club and walking to an after party after 2am... With that said I do not feel afraid or threatened at night time or anytime in Hollywood.
Another factor that makes the condominium market in Hollywood a bit unbalanced is that there are not many condominiums compared to apartments. The rental market in Hollywood is much more dominant and predictable. When I saw Chad Roger selling a penthouse at the W for $5M on Million Dollar Listing I thought it was a very sad joke. I would have never advised something like that to a client - it was practically money going down the drain.
