Abstract: A real estate data system deploys smart contracts on distributed ledgers. The smart contract includes data identifying real property, a lessor of the real property, a lessee of the real property, a service provider that will provide services to the parties to the smart contract, terms of a lease agreement between the lessee and the lessor, conditions to be met when transferring the lease from the lessee to another lessee, or any suitable combination thereof. The lease agreement may be a lease with an option to buy (LOB) agreement that includes an option for the lessee to buy the real estate agreement and terminate the lease at a predetermined strike price. Use of a LOB instead of a sale may be enable participants to trade real estate without losing the advantages of below-market interest rates of their loans. A service provider may act as an intermediary in the lease transaction.
