Thank you all for your valuable insights. 

However, in my opinion, since you are a new investor, completing a successful transaction and allowing yourself to gain experience by getting a win under your belt is more valuable than the Return on Effort itself.

I think that could be much more valuable than @Adrian Clapp's link that pertains to commercial property from someone who clearly lacks understanding of the metro area.

You've given me some very valuable action steps to figure out what works best for my position.

Clubs and Associations: Are there any clubs, associations, or networking groups that you found particularly valuable for connecting with potential borrowers and other industry professionals?

I'm still looking for a general contractor, but I don't have regular deals to make a GC's time valuable when estimating each job.

Having phone conversations and making sure that your screening process is on point are much more valuable.

These will most likely be used the hosts your connect with or can be introduced by you as a great selling point for why you are valuable.

We dealt with rentals, flips, commercial, small apartment complex developments (~10 apartments), sport facilities, and a few government contracts.We are actually very open to different opportunities and investment approaches, but our plan was to start "smaller" with some cash deals in NJ (maybe somewhere in the area between Staten Island and Philadelphia, but staying in NJ), by flipping a few smaller properties and starting to generate some income.

Networking with other investors and seeking advice from financial advisors can provide valuable insights and help you avoid common pitfalls.Keep an eye on your financial health by maintaining an emergency fund and avoiding over-leveraging.
