Exept the part where he verified service with two broadband providers before buying the house. Both lied then claimed they'd made an error. Error or lie, he relied on their information to his detriment. There's even a phrase for that in the law. Detrimental reliance.
I just went throught this crap last year when I was shopping for a house. I had a wonderful region picked out but had to scrap it completely because nobody down there could tell me what internet service was available. "That's the first question people aske these days." "So what's available at this location?" "No idea." They seemed to think that satellite and 3 meg DSL were acceptable options. I started doing my own research and quickly learned that most providers lie, lie, lie. Frontier was the worst. Every address but one came back as "25mbit fiber". Even the place that was 10 miles down a dirt road. The only one I trusted was the cable company but their footprint was tiny. If I didn't buy a place in town, I was SOL.
I ended up looking closer to The Big City and only requested viewings of places where the cable company assured me they provided service. And the first thing I looked for was the cable company's box on the side of the house with a fat coax line coming out of the ground. If the place didn't have existing service, I didn't bother going inside. Except for that really creepy house that was more of a dare than a serious look. Who puts the kitchen in the basement???
But getting back to the point, good internet service is as important as a good water supply. Without it, the property is useless for most people. I'd even look at a place without electric service before I'd look at a place with no internet. I could set up a solar/diesel/battery system for power but I can't build my own high speed, low latency internet service.
