I will got 3 house when I sold my house then buy bitcoin with that money
In short you should know that this won't happen overnight because
bitcoin is not a "get rich quick" scheme! That's right, bitcoin is a "get poor slow" scheme! 
Your houses, your choice,
but you could also just rent out the houses, and use the profit to speculate,
that way if btc drops to $100 , you did not lose your entire investment, just a year or so of rental income.
Good Luck , no matter what you choose.
