I work in a private real estate agency here in the States. We have experienced a spike in interested buyers and renters from out of state and abroad. We want to reach out to them to create a single, secure platform with property details (and images) and with services for all players at every stage of the buying/renting process. In other words, a site that provides a secure space for realtors, customers, notaries, inspectors, and government services to take part and make the process easy. What kind of platform or technology would I need to use to make this kind of process and data management easy and effective? I am leaning toward cloud-based or blockchain-based, especially since I know that blockchain-based smart contracts are very reliable. Any advice or assistance?
