There is still a lot of vacant CRE in OB/Point Loma/Midway/Morena/Rosecrans areas I follow.
The area behind Sports Arena, Kurtz and Hancock streets, is at least half empty and costs less than $1/sf generally.
I like the area, if not the immediate vicinity, problem is there are multiple adult bookstores there. I do not want to be close to one of those. At some point though the Internet will put them all out of business like regular bookstores and Blockbuster.
Overall the trend is for people to do more at home: work from home and shop from home.
Visiting the midwest, you see a lot of older suburbs where every house has an owner or a tenant, every house has christmas lights on the facade and cars in the driveway, but then half the strip malls are boarded up and empty.
I’m sure San Diego’s big shopping malls with tourist business will continue to do well, but Amazon is getting very aggressive into every last aspect of retail, even furniture and groceries.
