You should consult with an attorney in NJ who specializes in LL-T law. 

I’ve consulted attorneys and they tell me to “wait and see if he fixes the issues” One of his workers told me he was using my money to finish another job and was waiting on that payment to move forward with mine. 

The loan consultant i met online referred me to this lender had a valid NMLS.

First off, I do want to state that I'm not a lawyer and that you should consult your specific situation with your lawyer for the definitive answer. 

You can also consult with lenders, brokers and ask them for suggestions on who might be a good real estate mentor and most will be able to provide one.

After giving the past tenant time to pay the bill the property management company then sent the tenant to collections without consulting me. 

+1 for consulting your CPA for this type of question.

I've just seen too many unrepped buyers who think they're getting a discount by going directly to the listing agent, but they usually actually leave money on the table or screw up in one way or another without even realizing it (negotiating poorly/ not negotiating at all when they should, paying fees the seller typically pays, missing deadlines, misinterpreting inspection reports, not getting a sewer scope or radon or other things like a meth test or structural report or consulting a lawyer when appropriate, selecting most recent mill levy instead of prorated taxes for last calendar year when taxes went up 30% since last year are just a few examples I've seen personally).

Review with and consult a CPA.

This is a very complicated situation and you will need to consult a commercial mortgage broker (Like myself) Commercial properties have completely different loan terms than residential and are rarely 30 years fixed like your accustom to.
