Those pics are pretty bad, but I've seen worse when my parents decided to try to get into the real estate market a few years ago. They picked up an almost-foreclosed-on home of an animal hoarder who apparently had never cleaned since she moved in - we're talking years' worth of garbage, rotten food, feces, cats, dogs, rabbits, ferrets, etc. here. How someone was able to live in it and not be chronically ill is beyond me. It turned out to be so horrid they had to basically strip the house down to the studs and concrete slab and start over to make it habitable. They even had to throw out the refrigerator and other assorted appliances as they couldn't be salvaged.
