IMO the region near those condos and apts. off Carrol Canyon Rd. is the worst area of Mira Mesa. That’s where lots of crime happens due to the proximity of an easy escape route (15 fwy) so there are a lot of thefts and other things going on over there. Cars get snatched from the Edwards Cinema parking lot all the time so watch out next time you take in a movie.
IMO the 2nd-worst area would be Cam. Ruiz from MM Blvd to Capricorn and about 3 blocks deep to the East/West along that route. Lots of ugly, old condos, houses, and apts. and some crime as well.
Of course some of the commercial/industrial areas have crime but I’m just talking about places where people live. I would not buy in the areas I mentioned.
