I do not think that's a good idea. Because the growth of bitcoin is unstable, it is constantly changing and no one knows anything. I do not want the house to lose by bitcoin if it drops to $ 5-6k $ or $ 2-3k.
Today bitcoin prices are difficult to rise, the number of users may be a factor, they do not want to invest long-term, when looking at prices rise then they immediately sell, profit taking action like this is difficult to avoid so selling home is an illogical idea.
