Hi @David Fawcett, @Jim Wilcox,I'm also seeking recommendations for this area. 

First off, semantically  speaking, your discussion lacks a definition for the word "Legal"  While there are contracts in which a breach is a punishable offense, I am assuming you mean "Legal" in the "right to seek compensation for damages" sense.   

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

You should probably hire a professional (lawyer or consultant of some sort) to take a look at everything and outline your options for you. 

Im a beginner on long island ny, i was looking to hear back from other new york real estate investors to find out if the long island market is a good market to wholesale in, ive been looking into some potential leads ...

You will definitely want to get residents on the new lease agreements so that you can manage the park in a professional manner and enforce rules.

ALL I can say is to seek help and comfort and DO NOT give up; people want to help, I want to help...

I spoke to my other two tenants below her who informed me that they do not have a roach problem in their apartment so problem is clearly this upstairs tenant.I told her i would have a professional exterminator come to her apartment and have it sprayed.  

This is equivalent to walking onto a court with a professional basketball team as a 5'6" teenager with no shoes and telling them you want to join their team because you read a book somewhere that told you it was easy.

I graduated College in 1996 and got my first professional job in 1996.Then I said to myself..... who do I really want to get rich?
