Thanks for the help. I have tried the Dallas County Appraisals District with no luck I think the system is down. Also there are no spaces in between the houses ,each house is a duplex though. We will be checking with the police dept here in a minute, but I did tell him to stop the post man tomorrow. The thing is that we are trying to do this as anonymous to these people as possible. If we just call the cops they will go to my friends house and its very possible they will tell these people who the complaint is coming from . I am thinking the house is/was condemed and these people went and moved in. There is some weird things going on here and its getting worse. The neighbor has called the cops a few times but cops show up these people stick their head out of the other side of the duplex and say they just recently moved out. Cops say ok bye bye, couple hours later back in bussiness.
