Paying for a house with bitcoin sounds to me a mistake or lack of financial knowledge. Bitcoin is better than Fiat. Bitcoin increases in value and fiat faces inflation. Why then would one spend Bitcoin instead of fiat on a house rent which may expire in few years? Accommodating the Bitcoin can birth the person more money to pay his next house rent. But fiat wouldn't add any interest in the bank. Moreover the house owner will not hold the Bitcoin.
What if you pay rent with bitcoin and the Bitcoin drops to half of the initial deposit? Like play a $300 rent with bitcoin and immediately he reacieve it, it fell by %20and later futher drop and he losses, so I think it has the negative and the positive side. don't only tell us the positive side and neglecting the negative side. I think Bitcoin is for personal investment and not what to use anyhow if your. Instead you na sell your Bitcoin to fiat .
House owner has to pay bitcoins monthly which will equal $100, it's not a fixed monthly payment in Bitcoin, it's USD value converted to Bitcoin. I think that in this deal the person who pays for the rent buys Bitcoin on exchange and sends it to the house owner or he hopes that the price will go up and he will pay less and fewer Bitcoins each month. I think that first version is the correct, he converts USD to BTC and pays the rent. This deal will be done to gain attraction and write a history, just like our Bitcoin Pizza order has happened.
