Final answer:
An accurate year of purchase for 'the Mill' by DHD Ventures cannot be provided without additional context. DHD Ventures is a real estate developer involved in various projects, and the specific 'Mill' in question must be identified for a precise answer.
Step-by-step explanation:
Without specific information regarding which 'Mill' you are referring to, it is difficult to provide a precise year in which DHD Ventures purchased the property. DHD Ventures is a real estate development company that has been involved in various projects. To provide an accurate answer, more context about the specific 'Mill' would be required. For example, if this is in reference to a particular historic mill that has been converted for other uses or a specific redevelopment project by DHD Ventures, identifying the exact location or providing additional details would be necessary to determine the year of purchase.
