We have to pay people to house sit when vacant, there are some rough areas, but I believe the proximity to NYC, major court systems, universities, ect parts of Newark have possibility for significant appreciation, and even if they never go up I still have great cashflow. 

@james @James Lee probate is a great niche to get into  you will just have to look online for leads or go down to the court...stay consistent in sending your letters..pick up the phone and call theses attorneys..

Pay particular attention to court records.

Two very powerful tools that helped me from going to court over every little thing.

The condo association handles exterior building maintenance and grounds maintenance, as well as the swimming pool and tennis courts, as well as interior maintenance for common areas. 

It would seem a creditor could, but can the trustee or court and how far will they look back?

I am going to instruct the manager to never use the property address in the title when posting these videos (lest something serious ends up being used in a court of law) but should I go further?

They are in the business of sueing people and would rather deal with you in court than work something out.

There is a very likely outcome that you will be holding a note with an uncooperative homeowner/squatter, you will get to pay attorney/court fees and insurance costs while receiving no payments through a long, dragged out FC process, and then the pot of gold at the end 18 months later is a trashed house that is worth half what you hoped and you will have to pay up the 2 years of unpaid property taxes to boot.Just remember, there is a reason these existing lenders are dumping the note rather than doing a workout themselves.

Not sure which way the courts would go, but the minute you are sitting in court on an issue like this, you've lost already.
