Multi-family, professional office or very high end retail is the way to go.

A person, with absolutely no professional certification, claimed to be a property manger, offered to mange my house, claiming that he has all the professional certification and promised to fill out W9 form for me when he is to be paid.

I'm a young professional looking for area near beaches, shops, nightlife, etc - but willing to live in a outskirt to save some $ on my residence and invest in more of the prime locations for rentals.

I recommend you seek advice from a local professional.

Any profession requires it, if you're going to be a professional.

Professional greetings go a long way.

For now, I have professional people in Arizona.

It is not a substitute in any way for professional advice and some advice here is ok and some just plain bad, but overall this is an incredibly GOOD source of information for investors at many levels.

Better yet, just pay a bit extra up front and get tailored, advice from a trained, insured, professional. 

Hire a professional if you want the facts.
