There is no hard and fast requirement. According to the inquiry of the real estate network, there is no rigid requirement for the delivery time of resettlement houses. There will be a delivery date when signing the purchase contract. The construction of resettlement houses will take two to three years. To purchase resettlement houses, you need to go through the formalities with the construction unit, and then deliver them after the formalities are completed. If the developer fails to deliver the house as scheduled, he can file a lawsuit with the relevant department and obtain the corresponding claim.
