In just 8 months the replacement dryer is no longer working properly (sounds like same problem as last time- the clothes aren’t drying completely).

They need to clean their clothes and bedding to get rid of any eggs.The professionals I have spoken with tell me that bed bugs normally do not travel (like roaches). 

Other rooms were cluttered and wall to wall clothing on the floor.

I am quite sexist about it, but women who start to show me contempt after they see me get my hands or clothes dirty fixing something in their house...there are quite a few of those ladies out there, sad to say.

They had moved in a fair amount of personal belongings, mostly clothing, and had removed two televisions.  

I can tell you some stories about how he spoke with people on the phone he never met and he described the clothing they were wearing, their height, whether or not they had a mustache, when they had a morotcycle, what brand motorcycle and even the pattern and color of their clothing.

Do they test their kid's clothing after a week at camp?

If you don't blow money on fancy cars, alcohol, eating out, name brand clothes and vacations, you can live just fine. 

.- Add a nice dresser and a mobile clothing rack.- Add a washer and dryer in the bathroom Anyway...any input appreciated.

I would not recommend it as sound damping between the floors.
