In the US, realtors charge a broker fee, typically 5 to 6% of the selling price, for  bringing a seller and a buyer together to make a real estate transaction. Lawyers charge hundreds of dollars for providing legal services to a buyer or seller. In New York city, a real estate broker typically charges a customer one month of rent, which is often thousands of USD, for facilitating a rental transaction. This is quite expensive compared to the limited services provided.  Blockchain provides a much lower cost solution with the added value of providing transparency. A real estate blockchain network matches untrusted buyers/sellers or tenants/landlords for a deal. The scripted legal document, a smart contract, replaces mos legal services provided by a real estate lawyer, thus rendering them nonessential. No escrowsing accounts are required since blockchain combines transaction and settlement into one action. In other words, transferring ownership of a house and payment occur at the same time. A similar solution is applicable in the case of property rentals. This will lead to dramatic savings in transactions by both parties. Facing the threat posed by blockchain technology, realtors will either have to find an innovative way of providing value added services or change to a different occupation.
