Section 03 — Why Now
The window between announced infrastructure and operational delivery is when waterfront pricing repositions. Three catalysts converge between 2026 and 2030:
01
Gran Malecón del Mar — delivers 2027
Marbella's beachfront experience transforms, with espolones already 100% complete in this sector.
02
CACI new airport — construction 2027, operational 2030
Northern Cartagena corridor revalues as international connectivity expands.
03
Rafael Núñez modernization completes
COP $887B investment doubles current airport capacity, supporting near-term tourism demand.
Buying ahead of these deliveries is the difference between entering Marbella at $7M/m² today and $9–10M/m² in 2028–2029.
Section 04 — Why Cartagena, Colombia
2025 is a record year for Cartagena — and the numbers point to a city building infrastructure for the next decade, not just the next season.

446K
Cruise visitors in the 2025-2026 season, +20.1% year-over-year
$53.5M

Section 07 — Why This Building
Built in 2013, Terrazas de San Sebastián is one of Marbella's most respected addresses. Strict residential regulations keep it a community of owners, not a hotel. Google Reviews — Terrazas de San Sebastián
Section 08 — Why This Apartment
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 09 — Investment Numbers
5-Year Base Case
Projections shown in COP nominal terms. Currency exposure to USD or other home currencies should be evaluated independently by each investor.
Section 10 — 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 11 — Location
Marbella sits between Centro Histórico and Crespo — close enough to walk the walled city, far enough to escape its tourist density.

A clean title, a clean transaction.
