I don’t like the residual airport noise that prevalent in Ocean Beach. To me that is no deal right off the bat. I also think that family of 6 is going to want a larger home with a larger lot. This is also something that is harder to come by in Ocean Beach. Most families with 4 kids also are looking for a particular level of construction quality. OB has a predominant older housing stock and there is a higher probability of needing some remodel or construction then other locations.
I am not big fan of suburbia either and the beach communities in coastal San Diego offer a pleasing respite from that.
Based on experience of what I am asked for by families seeking to buy a home in San Diego, I have never been asked by a family with children to relocate into Ocean Beach. I have been asked by people without kids to live in Ocean Beach, (both younger couples and empty nesters). The predominant destinations I get asked about are those that the poster originally listed.
Without know what the OP likes, I have to run on assumptions. I then really on the numbers rather then the outliers.
The question is not whether you or bg like raising your kids. Nor is it where I would choose to raise my kids. It really is where the OP likes to raise their kids and what kind of lifestyle they want for the children that they have. I think a more rational answer is one like I posed which is come out here first. Live here and rent for awhile before you make any decision.
