You mean, real estate would be priced in Bitcoin, and transactions would be carried out in Bitcoin instead of USD, the way they are today? That would be awesome! A huge vote of confidence in Bitcoin! It would really go a long way to damping Bitcoin's price volatility worldwide, too, by essentially pegging it to physical-world goods with durable value, even if they aren't portable goods.
It's true that if you can update prices instantly, offering a trade doesn't stabilize the prices of the things you are offering to trade. But that is not how the real estate market works; bids and offers are made with a validity time measured in days or weeks, not minutes, and asking prices are often printed in office windows.
But it's a silly idea. It's not going to happen, and the point of my comment was to explain why.
