There is certainly room to disrupt the Real Estate market. NEM issues tokens tied to real world assets already. They have smart contracts. They are already used to trade assets in the real world. It is not clear why this or any other Real Estate-specific coin would do that job though. It is also not clear how they expect to solve the problem of fake reviews, seems like Steemit has a better solution model. In fact, I think Steem could be a great way to run rentals specifically.
