Long Beach, NY - New to this market and would love your input

Hello, I am new to the Long Beach, NY market and I am looking at this market both in terms of a primary residence and an investment opportunity. 

I have noticed a number of duplexes and triplexes on the market and am considering a house-hack approach.

My questions: 

What are some of the pitfalls with owning in Long Beach, NY generally and owning rentals? 

Are there any special assessments / local taxes/fees to be weary of from Sandy or in general?

What sub-markets in Long Beach are most recommended (Lido, northshore, southshore, close to train, does it matter?) 

I'd love any of your thoughts / opinions on the market! 

Thanks,

Colin
