I recommend investing anywhere your numbers work. That is, if it's a deal, then it's a deal and if it fits in with your strategy and goals, then you try to buy it. @David Greene, @Alexander Felice, and others have helped me understand that you live where you want to live and buy where it makes sense to buy if they're not the same place.
There are many buy and hold investors making it work in the CV - so it is possible. One BP member, @John D., has an interesting strategy of buying larger, higher-end homes, adding rooms and amenities and then renting them out as short term rentals - especially for events like Coachella/Stagecoach or the BNP Paribas Tennis Tournaments. You may want to reach out to him.
Like those successful buy and hold investors, I see potential deals all the time. Regrettably, I lack a sufficient war chest, for buying at the price points most of the rentals are going for in the CV. I chose Jacksonville, FL for a number of reasons, but the price-to-rent ratio was chief in my analysis.
I hope that answers your question!
