Recently, I have seen several real estates, some of which are still under construction, but the sales girl said that they have been sold out, and some houses have been built. Why are they still selling? For reference only: recognition is a predetermined concept, which means that no matter when the property is completed, you will have a copy; The opening is the day when the real estate developed by the developer is sold for the first time. From this day on, real estate began to be sold one after another; When you say payment, you should mean the payment of the mortgage, and then the bank will give the payment time after your house loan procedure is approved by the bank. There is no fixed interval between these three periods in the operation of different buildings, which depends entirely on the progress of project construction and various procedures, as well as the auspicious time chosen by developers.
