I would look at license electricians to do the work which might be in this range.

I have a teaching license to teach business in middle and high school charter schools (but i havent actually taught at this level yet)  I am an Enrolled Agent and work seasonally for Intuit in their Turbo Tax division. 

That will get you the proper coverage and you will know the correct costs from the start.

I have a auto body shop that is located in a D class residential area, it was own by my grandfather, he is getting up in age and he is passing it to me. he hasn't done body work in years, he just have been renting the place out to some guys he know for like $220 a month. the utility are still in his name also. my whole idea is to come in, change things around, do the proper things, have a actually lease agreement written out for the tenants, with the new rate increase and rules, there wont be anymore of the late rent payments, there will be a late penalty, the utility will be in the tenants names,I plan to put a security system on the property, I'm new to all of this , its my first property I'm open to advice, suggestions, ideas on what I should do.

Ground Up Construction loans (for 1-4 unit investment properties).The principals of 11 Capital Finance have been in the commercial lending business for over 20 years and know how to properly advise a borrower on any type of commercial real estate transaction.

And I'm contemplating getting my RE license. 

I'd never trust the numbers of a homeowner, unless they were a licensed contractor themselves, and even then, I'd double-check and verify everything myself.Since you don't know any contractors, I'd reach out to your network (friends, family, coworkers) and ask for references.

I feel like long term the Hudson County area properties will continue to appreciate as demand gets pushed here from an increasingly expensive New York market.Are there any experienced real estate investor's with their brokerage license that can sit down with me discuss my options moving forward. 

Hi Karl, Congrats on your new move to get a license!

The fact they are complaining online might be an indication the property manager dealt with them properly so be sure to ask the manager for their side of the story.I hope this basic guide helps.
