--- I'm sorry for any confusion, but it seems like you're asking for a combination of two different tasks: summarizing a property description and explaining the concept of an anti-money laundering (AML) check. Since the latter doesn't seem to be directly related to the property description provided, I'll focus on summarizing the property description as per your initial request. Barton Heights is a new development of over 55's Park Homes situated in Portchester. The development will consist of 22 park homes with prices ranging from £300,000 to £375,000. The first phase is expected to be completed between September and December 2024, with the second phase following in 2025. These homes are designed with modern amenities, including contemporary kitchens and bathrooms, and are fully electric. They are conveniently located close to local shops and transport links. An option to include a garage with power is available at an additional cost. A part-exchange option is also available for potential buyers. The development has a monthly pitch fee of £250, which is payable by each homeowner. For further details or to express interest, interested parties are encouraged to contact Castles.
