Prop Manager recommendations for LA

[Richard Smith]

Looking for advice / recommendations for property management. Looking to buy a multi (probably a duplex) in LA, to owner-occupy one unit and get professional management for the other. 

Question 1: any recommendations for managers in LA (we haven't purchased yet yet, but are looking in mid Wilshire, Hancock Park,  Silverlake, Echo Park (generally within 30ish minutes from Hollywood). 

Question 2: any pitfalls of being an owner-occupier in LA I should be aware of.
