I've used the following description to explain it before.  

Please be specific in your description.

He only works one or two projects at a time, and is somewhat selective about who he works with, what kind of projects he takes on and what geographical area.

Kenny has some good advice.I am somewhat confused by your description.  

Since I am from Dallas Texas and I have never been to the northeast so I cannot really suggest any geographical moves.  

You can do this locally, but most non-performing investors are not geographically constrained.Many more moving parts than performing notes but you can expect to make a huge percent return on any one note and get wiped out on others.

Appreciated if somebody would give a general description of good/decent areas for SFH and bad areas I need to avoid.  

They turned up nothing, not even a job description. 

A couple of points for the ad  Less words  Include: description e.g.  1 b/1 bath then specify  Included items wifi etc and  at the end qualifications.
