Everything is included in the sale:
The buyer arrives with a suitcase. The penthouse is ready the day of closing — no renovation, no furnishing budget, no waiting.
Section 08 — Investment Numbers
5-Year Base Case
Section 09 — Who Is This For
You see Cartagena's infrastructure trajectory and want waterfront luxury at the lowest entry point on the map — before the Malecón and CACI revalue the entire coast.
You want a turnkey Caribbean residence for school holidays and long weekends — fully furnished, with stable residential neighbors and controlled access.
You want top-floor duplex luxury in a UNESCO city, walking distance to the beach, at roughly half what comparable Bocagrande or Castillogrande units cost.
Section 10 — Location
Marbella sits between Centro Histórico and Crespo — close enough to walk the walled city, far enough to escape its tourist density.
