The spot price of real estate refers to the price with the current real estate as the transaction target. The present situation of the property may be a piece of land that is ready to be built but has not yet been built. It may be a project under construction or a built property. When the building is a completed property, it is the existing house price (land price). The futures price of real estate refers to the future price of real estate, and the most common is the auction price (including land price). Auction price refers to the price of houses (including land) that have not yet been built but will be built in the future.
