we might also have different definitions of roach infested which is why there is a disconnect.
For me anything that smells like animal, animal urine, dead animal hair in boxes ..etc. that goes in a heartbeat.
Any soft good from a really really dirty room goes straight to the dumpster ..etc.
The rat room I got was a 10x30 packed to the ceiling. The rats were all in the bottom. After skimming off the first foot or two I kept the rest and sold.
I've also had rooms where I made 10x my money in the first couple of feet, did a quick sort of the other stuff and tossed just because I didn't have the time or interest to sort, store and sell the balance.
For me winter is my time to buy all the big units. Most people don't have the space or dont want to work out in the cold so I start picking them up for prestoragewars days. The cheaper I buy them for the less I have to be a miser about every piece.
Also my family thinks I'm the black sheep of the family because I do this. However I make more part time than most of them do full time sitting in a cubicle farm wasting their lives away.
