@M Marie M. I would definitely want to house hack but I'm just not trying to share the same space with roommates (bedrooms on same floor, sharing kitchen, bathroom, living room). A property with a basement would be ideal for me, I don't mind sharing a property with someones, just as long as they have a separate unit for themselves. My sentiments come from having 11 different roommates in college (from undergrad to law school students) and dealing w/ the lack of respect for the living area/other roommates was enough for me to be opposed to having roommates again.
Having said that, I think the type of people chosen would be very important and I think I could be a lot more particular about what I'm looking for in a roommate if I decided to go down that route. The temporary roommate situation sounds like a good idea to me though and it would probably be easier for me to deal with.
As far as carving out legal basements, have people found this to be difficult? That would be something I'd be interested in if I was unable to find a property that already had a basement. Thanks!
