It's a great meet-up, I'm a relative newbie there myself, and I've found it very valuable. 

I found in Rochester a few different markets, each has advantages and disadvantages. 

Same website, different area, is where I found tax delinquent.  

Rent trends can be found at https://www.zillow.com/research/data/ and metro occupancy trends at https://www.census.gov/housing/hvs/data/rates.html

I know a lot of agents, but I have found that it seems to be hard to find an agent who is investor friendly, some tell me I am offering too low and I don't hear back from them, but I offer those prices because that's the price I need it at to make our profit.

I found BiggerPockets from reading "The Book on Investing In Real Estate with No (and Low) Money Down: Real Life Strategies for Investing in Real Estate Using Other People's Money".

I have found good amount searching through zillow and realtor.

I have found that the best way to enter any business networking or relationship in general is go in with no agenda, simply go in with the idea that you would like to make friends. 

I have invested in a number of their portfolios already, and I wrote about it after my first investment with them:  Have I Found the Holy Grail of Passive Real Estate Investing?

I found very little interest from craigslist cold calls/emails.
