It depends on the kind of house. It also depends on the amount of bitcoins you have.
I personally would not buy a house if I had to spend more than half of my Bitcoins on it. A house is something you can buy later, Bitcoin is an opportunity that happens once in a lifetime.
I agree with you it depends on the amount of the house that you will buy if it fits in your funds. Personally, I would'nt buy a house I could still save and hold my bitcoin for it to grow my investment. I can still buy a house if I wanted to but more likely I must convert it into fiat.
