A lot of opportunity for the BRRRR method.

As a fellow New Yorker myself I can tell you that prices will not make house-hacking easy or even worth the time and money your going to burn through.I highly recommend attending various networking events and deciding what kind of investing you want to ultimately do (I'm assuming this house hack method was designed to help you achieve something long term). 

Google the enemy method.

Insurance companies use this method when determining their policy pricing.

Could you advise on the best methods to find a mentor and network with professionals in this field?

That is a really neat method!

The Enemy Method is the best thing you can do to comp houses. 

My plan is to buy a duplex or triplex that I can cashflow through rentals and add value then ultimately refinance and buy more (brrrr method).As of right now I am working through the process of deciding on which market I want to invest in.

You'll take title, but it will be suject to (not to be confused with the popular purchase method) the superior lien position.
