The next stage of cooperation in the event that the initial information about the developer satisfied you, this is a check of the relevant permits. The developer must provide you with a positive withdrawal of the state construction examination, work documentation of external networks and a construction order, as well as a document confirming the right to the land plot on which construction is under construction. Experts advise checking the documentation of the developer even if the construction is completed by 99%, even such houses risk remaining long-term construction if the developer does not have any necessary documentation.
