I have lived in all three areas over the last 9 years as a renter.
Santa barbara for four, Lompoc for one, Oxnard and Ventura for the last four.
Personally. I currently commute from Ventura to Goleta every day. Honestly, the traffic is much worse in Santa Barbara and carpenteria during rush hours than it ever is down south.
You have a strong rental market in SB due to the university and price of the homes being out of reach, but the market is just as strong in ventura/oxnard due to the population and location is optimal. Ventura county your average tenant will rent longer and take better care of their homes overall since you can offer more.
All the units ive ever seen in Santa Barbara, unless you pay a fortune for them, are very outdated and no owners seem to want to upgrade them so long as people are still renting; probably due to the already high mortgages, which isnt fair to the renters. Almost inevitably your renters will end up leaving to one of the surrounding cities for better living. I love living in Ventura and would have no reason to go to Santa Barbara if I did not manage a business up there. Creature comforts and things to do are much more accessable in ventura and oxnard and is a much more optimal place to live overall. Santa Barbara just has beautiful scenery, which I love, dont get me wrong.
Lompoc was not a bad place to rent however very small and not much to do got bored quickly and the commute to SB is always atleast 50 mins, where with not traffic could be 30-40 from ventura.
I think it is worth looking into Santa Maria as well since it has been rapidly growing and gentrifying. Still pretty affordable (priced between lompoc and ventura). In the end, youve got to look at which city has the highest cashflow and where youd like to live. After analyzing many deals, it seems hard to cashflow anywhere on the central coast until you have a large amount of equity in the home.
Best of luck, i am looking out of state.
