I use Able property management. They're pretty decent. Just make sure to keep tabs on any property manager.
You should check out the website rentrage.com. It costs about $1 per search for rental comps. I'd then look at all the addresses of the rental comps and try to find pictures online and add or subtract rent prices depending on condition.
The local economy is OK. There's a lot of logistics and warehousing that has helped overcome the oil crash. Ag isn't doing very well b/c of the drought, but I haven't heard of very many lay offs like the oil layoffs in ag.
As far as sales, anything over about 220k is sitting on the market for a long time. Mid range properties are still selling (120 to 190k).
Middle range rentals are probably a good bet right now. I think the higher end of the rental spectrum will experience longer rent up times judging by the higher priced sales sitting on the market. Low end rentals in Bakersfield I don't really mess with so I don't have much to say about that.
