I think it's a brilliant move on the owner's part. This thing has gone viral, and I suspect they'll get well over market value for the property. I'm honestly very tempted to give it a try. Owning a B&B was my first idea for achieving FIRE, before I even knew what FIRE was. I still like the idea of it.
As far as taxes - yeah, you're going to get reamed. So you have to take out a mortgage to pay the taxes. You still come out ahead by at least half a million. Immediate FI would be worth it. I doubt I'll apply, because I don't like the odds, but it's better than playing the lottery.
