I’d suggest beginning by connecting with an agent who specializes in multi-family properties.

Looking to make some great connections.

Then connect with some hard money lenders (you can find some here on BP as well as some who are typing this right now) and connect with them to understand their product type, what they like to lend on and requirements.Hard money broker is all numbers game of making relationships and helping those that are looking for financing, it starts out slow but if you get with a few good borrowers and lenders it can be pretty decent money to be made.As an example we paid six figures last year to HM brokers. 

I would like to connect with like minded individuals.

Quote from @Simon Horowitz: I'd love to connect on here with trustworthy contractors that I can bounce ideas off. 

You're in the right place to connect with local Chicago investors.
