Why did the house I just rented in Rainbow disappear at once? What happened?

Because Rainbow rents a house free of commission, there are preferential activities and many tenants. Maybe someone rented this house when you were looking at the house. Moreover, in order to ensure the authenticity of the information, the houses they put on the Internet are cancelled in real time. If they are rented out, the house information will be deleted, so the house you like may be rented out.
