I don't think BTC1 is enough to buy a house in my place/city, to get decent house it takes at least BTC10 that cheapest .
For now, with 1btc you may rent a house within 6months-1 year. I guess it need more than 8 years to reach good price per 1btc to be able buy a new house but every year it costs more (price increase) to purchase a house, right. I hope we could reach $8K per BTC1 in the next 8 years later, step-up $1000 every year.
