It depends on the property and your market, but I would start social media profiles for the property or your brand if you plan on expanding. 

And it will get much worse (office values have collapsed) both from pure economics and idiotic social policies.

Again, I have a bias against "gurus", and the bigger the social media following, the more skeptical I am.  

@Vy LeRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

Depreciation is finite- with each component you accellerate, you will empty the bucket for future depreciation of that component. 

And don't forget the other component of real estate investing you lose in an exit - depreciation.  

Connect with others in the real estate community—whether it's through social media, forums, or local meetups—to find opportunities.

For newly constructed, purchased or renovated properties and also retroactive generally over the last 10 years, building components are properly classified into individual units of property and accurate recovery periods for computing depreciation deductions.

Any suggestions on where to start, what to look for, recommended reading or social events.

I promise it beats trusting social media gods.Investor list nurturing requires consistent communication.
