well, it sounds good but I do not think it will happen in the near future, maybe 5 or 10 years from now, because crypto is still unacceptable all over the world but it will definitely be accepted in the end, because nothing can prevent technology.
but I really support it.
No, it is possible now to buy/sell a house for bitcoin. Check this article:

What I mean is, as long as using crypto is not a problem within your country and both of you (seller and prospective buyer) agree to do the payment in terms of btc then there's no problem at all.
