I just want to throw out there that my husband is an IT consultant. With his current contract, he's gone four days, home three. He's also done two weeks and two weeks, and 100% remote. For us, it works very well. I also know he has some consultant friends that are doing exactly what this guy is doing--living with roommates and traveling a lot. I see nothing sketchy about his arrangement, and I also think this is something that can be easily worked around. I can understand his hesitation, though, especially if he's done long distance and it didn't work out well.

Basically, all I'm saying, is that his work/living situation is not necessarily a red flag.
