As I feel they had some legal obligation not to sell the property or remove the forged satifaction since the notary did tell them it was fraud prior to sale.

Then they put some young guy up front for an intro cracking corny jokes and telling us he now makes so much money he legally can't tell us what he makes! 

What is the fastes legal action to take in NJ to get access to the rental house? 

In my state you have to be 19+ years of age or older to enter into a legally binding contract.

I have bought 2 four plexes and looking to find the best structure with LlC , Lease and sub lease.

A great example is people calling around to find the cheapest title company (@Tom Gimer has discussed this) If you are doing a $100-400K transaction why would you try to save a few hundred dollars for good title work or legal advice.                                        

My question is, why isn't there a legal challenge against this law?

In Pennsylvania, we are tax deed, so a deed is issued, but it is typically delayed (legal process takes time).

By listing and renting on the OTA’s like AirBnb and VRBO you never lose the ability to occupy the property because they are not facilitation a legal lease agreement.  

2) Legal - I know licensed agents have a fiduciary responsibility (which is why I want to be transparent with the options and provide accurate numbers) but I want to make sure I don't expose myself to any legal issues down the road.
