Not trashed, no eviction, the renters simply decided to move to another part of town, and left the property in reasonable condition.  

Expensive legal counsel helps immensely of course.Although, there is still a school of thought that only the actual moving of dirt creates inventory and recording a plat is simply codifying best and highest use.  

Zillow simply pulls the data from municipalities and publishes it on their site.

I believe you should go off the partnership agreement.For instance a partnership (whole lot of them) had a hole in their partnership agreement (drafted in the 80s) where the management company (the person who created the partnerships had his own) could charge a set fee that would increase each year for some services.  

My note for you would be to take a much harder look at comps than simply through Zillow.

Knowing who negotiates in good faith and who is an a**hole,  knowing who can close and who wont (This extends to accepting offers with financing from certain lenders) all lends weight and credibility to the offer, or detracts from the offer.

Granted the RR has been fairly consistent between 5-10% and even up to 15%, some neighborhoods have been more adamant to meet and negotiate deals (which I believe stems from the demographic, average age of the residential area, and simply the culture of the neighborhood) My skill sets and insight into print marketing has been key in building an emotional response, and thus providing qualified leads.

NJ simply isn't Texas or the midwest in terms of easy cashflow.

The other 2%+ simply goes to the platform.

I can simply move out of there, move into the house and let the rent roll from the other property help with the mortgage for the one family.
