My read

My read on Watson Harbour: with the project this far along, what I tell buyers to weigh is the deposit structure, the delivery timeline, and how the floor and line affect light and resale, not just the launch price. If you are weighing 888 MacArthur Causeway, Watson Island, Miami, FL, those are the details that decide value.

This project is in an early, pre-construction stage. Details are not final and may change. Gerardo Gonzalez is an independent licensed agent at Compass providing buyer-side guidance, not the listing or sales brokerage.
