Technical inspection before the promesa: a dúplex (two-level unit) in El Laguito

A title review tells you who may sell; a technical inspection tells you what is being sold. They are two separate engagements, both paid for by the buyer, and in El Laguito the second one is usually skipped because the buyer is not in the city to open the door.

What gets inspected is not the same checklist for every property: when what you are buying is a dúplex (two-level unit), the report has to address what the nature of that property actually puts at risk, not a generic form about damp patches and sockets. That matters for money and for timing. For money, because a repair not found before the promesa de compraventa is signed gets paid for afterwards by the buyer, and in a propiedad horizontal (condominium regime) it can end up shared among all owners through a special assessment. For timing, because before the promesa whatever turns up is a matter for negotiation, and afterwards it is only a claim. The report is signed by a professional who answers for what it says; nobody signs the brochure.

A dúplex is bought differently because what you see and what is recorded may not be the same thing. Two levels joined by an internal staircase are lived in as one home, yet the registry may still see two: two matrículas inmobiliarias (registry folios), two ownership shares, two chains of title and two separate arrears accounts with the building. That gap between the physical thing and the legal thing organizes the entire purchase. If there are two folios, you are really signing two acquisitions that end up tied in fact but not in law, and each one can be taxed, mortgaged, attached and sold on its own, so a future buyer may find half a home on offer. If there is a single folio, you need to know when and how the merger happened, because joining units is an amendment to the reglamento and not merely building work. What gets examined here, then, is the identity of the property before its condition: how the unit came into being, which document recognizes it, and whether the copropiedad was ever told. For a buyer abroad, each folio may also carry its own paperwork and its own power of attorney.

The procedural difference here is not the land but the building: almost everything is older, dense propiedad horizontal, the condominium regime, and the decision-maker is not the District but the owners' assembly acting through its bylaws. Buying means reading those bylaws before any brochure, reviewing recent assembly minutes, and asking the building manager for the paz y salvo, a no-arrears certificate, the approved budget and any special assessments, because a repair levy already voted passes to the buyer who never voted on it. Since the area lives on lodging, the registro nacional de turismo, the national tourism registry, joins in: the provider must be registered, the bylaws must permit that use, and the two must agree, because one is demanded by a national body and the other depends on the neighbors. The counterparty is usually an owner already renting the unit, sometimes through an operator under a live management contract, so establish what transfers with the property and what stays tied to the previous operator.

What is specific to El Laguito

The tip of Bocagrande, surrounded by water on almost every side and given over to visitor lodging since it was built. Older, very dense apartment towers, with much of the inventory given to short stays and apartment-hotels. The only way in is across Bocagrande along a narrow road that ends at the point, with no alternative exit.

  • what the reglamento de propiedad horizontal, the condominium bylaws, say about renting by the night, since the assembly may have restricted it and that decides the business
  • whether the unit and the building hold registro nacional de turismo entries, the national tourism registry, and in whose name, because the duty falls on whoever provides the service
  • the condominium's accounts and pending lawsuits, along with façade and pipework upkeep in a building exposed to salt air

What to verify, step by step

  1. Ask the curaduría urbana (the private permitting office) for the licencia de construcción and the approved plans, and check what use, area and height that permit actually authorised against what you are being shown. Anything built beyond it is not cured by the deed.
  2. What the report has to address point by point for a dúplex (two-level unit): whether both levels sit on a single matrícula inmobiliaria (registry folio) or on two, since that decides whether it conveys as one property or as two; whether the internal staircase appears on the plans approved with the licencia de construcción or was cut later to join two units and how the coeficiente de copropiedad was restated after the merger, because if the reglamento was never amended the dues may still be billed twice.
  3. And what the same report should pick up for the sector in El Laguito: what the reglamento de propiedad horizontal, the condominium bylaws, say about renting by the night, since the assembly may have restricted it and that decides the business; whether the unit and the building hold registro nacional de turismo entries, the national tourism registry, and in whose name, because the duty falls on whoever provides the service and the condominium's accounts and pending lawsuits, along with façade and pipework upkeep in a building exposed to salt air.
  4. Engage the visit with an engineer or architect you hire yourself, not the one the seller offers, and require a written report with dated photographs, a signature and the professional's licence number. Ask Camacol Bolívar who carries out technical surveys in the region and ask for references you can check.
  5. Agree in writing with the seller on the date of the visit and on access to the property before signing the promesa, and attach the report to the promesa together with the agreed repairs and who pays for them.
  6. Ask the District whether any administrative proceeding is open against the property for building without a permit or for breaching planning rules, because that follows the property and not the seller.

Mistakes that cost money

  • Accepting the report the seller or the developer hands over. The useful report is the one the buyer commissioned and can question.
  • Leaving the inspection until after the promesa, when the price is already agreed. Whatever surfaces then is argued from the weaker position.
  • Confusing the technical inspection with the title review. One looks at the construction and the other at the chain of ownership; you need both, and not from the same person.

Frequently asked questions

Can the inspection be done without being in Cartagena?
Yes, and it usually is: you hire the professional, arrange access with the seller and receive the signed report. What you should not delegate is choosing who does it.
Does the inspection change with the type of property?
In substance, yes. What has to be verified on a dúplex (two-level unit) comes from the nature of the property —what is privately owned, what is common property, what the permit authorises— and not from a general list of finishes.
Who pays for repairs the report turns up?
Whoever agreed to in writing. If the report is attached to the promesa with the fixes and who owes them, you have something to enforce; if it lives in an email, you do not.
