This is a good question. I personally have never tried to but a house using Bitcoin or other cryptocurrencies, but, honestly, I would be really surprised if that is possible, given all the headaches that our government is imposing on us! I was planning to buy some real property abroad using Bitcoin or Ether. I will keep you posted if I manage to arrange for a crypto transaction!
This is a topic which is extremely interesting!
