Real eastate industry is very huge and also very slow in adopting new technologies. See example of SAP it was lauched in around 2000 and companies started to adopt this software from 2004 and still so many well known real eastate company are yet to be adapt this advanced software for accounting, material management, supply chain management etc. Than in this scenario blockchain will be adapted in real estate industry very slow. Although there have been so many ICOs are lauched and coming up based on real estate like blocksquare, alt eastate, wealth migrate etc but they are yet to be proove themself on market.
