The working capital is created from periodic advance payments deposited by the co-owners. These advance payments can be collected on a monthly, three-monthly or six-monthly basis or via a single annual advance payment demand. The frequency will be set by the general meeting, on the proposal of the property administrator. Syncura usually has three-monthly advance payment collections, the demands for which are sent to the owner in digital format. Payments are to be made within 30 days of receipt of the request for payment.
