If I bought a house at that price, I would have enough distance from neighbors and their annoying alarms
If I had $300 million bucks like that guy, I'd have a luxurious castle atop a formidable granite spire so far out in the wilderness that the landscape probably doesn't even appear on USGS satellite maps. I'd just have supplies flown in by helicopter when I needed it.
I even have some likely candidate properties in mind in Nevada, Idaho, and Wyoming.
A third of a billion dollars, and I could live the rest of my life making Lex Luthor look like a pauper.
