We didn't have to actually go through an eviction because she agreed to move out and clean the house if we would let her make payments for the back rent.

With no contract on the house he cant close anyway but I want my offer to be accepted and as clean as possible. 

A note is not a property and a property is not a note.NPN - again, no rules, but if you have a "clean" asset, and you have to foreclose... 50% or less of the lesser of UPB or GOOD BPO value is a target to look at.

they are for real.. but my dealings with them were that they are pretty well disorginzied.. but then again they are dealing with folks that have trashed credit... and usually not savvy to the financial world at all.. so it takes a lot of hand holding.. and at least when I sold.. they wanted me to give significant discount so the rate could be bought downat the end of the day though the buyer got a smoking deal.. but there is a huge drop out of those who just can't get through the program and probably never will clean up their credit etc.
