Let's have a very high bitcoin price and I can definitely tell you that my last problem would be the one of buying a new house. 
So, again: give me a high bitcoin price and I will act accordingly!
to be honest it is impossible for the bitcoin price to grow that much right now thus you wont be able to buy a house for your btc for a really long time in my opinionSo, again: give me a high bitcoin price and I will act accordingly!
though if the price would go up that much i think you should buy eeverything you want if it makes you rich because after some time the price might fall once again
