An avalúo comercial —a signed appraisal report— is not an opinion about price: it is a document a licensed perito avaluador stands behind. Before any money moves, find out who prepared it, by what method and for whom, because the appraisal the lender orders and the one the seller shows you are two different documents.
The method follows the nature of the property, which is why the appraisal of a house in a gated condominio is not assembled like any other. Where comparable units exist in the same sector the perito works by market comparison; where the subject is undeveloped land or a property with no close referents, the residual and replacement-cost methods appear, and those rest on planning and construction assumptions a buyer can read and challenge. On top of that sits a common confusion: the avalúo catastral published by IGAC —the assessed value— is the base for the impuesto predial, the property tax, and never claims to be market value. And an appraisal commissioned by a lender exists to measure that lender's own collateral, under prudential criteria that are not the buyer's. All of it decides money: how much the bank advances, how much the seller asks, and what ends up written in the deed.
A house in a gated condominio is bought differently because the home is individual while the small town around it is private. Roof, foundations and internal installations belong to the owner and the owner repairs them, no asamblea involved. But the road that reaches it, the water it receives, the lighting, the pool, the gatehouse and often the treatment plant belong to the development and are kept up by everyone's dues. Two questions follow, and they organize the purchase. The first is infrastructure: whether those networks were handed over to the Distrito, the city government, or remain private, because in the second case replacing a pipe or a stretch of road is paid by the copropiedad and not by the city. The second is autonomy: the house looks free-standing, yet extending it, repainting it another color, enclosing a terrace or changing the perimeter wall goes first through the condominio's reglamento and only afterwards to the planning authority, two separate processes with different criteria. For a buyer abroad, that means the home arrives livable while its surroundings are a shared account that stays open, and it pays to know which body decides what.
In Castillogrande the typical deal is not a unit in a condominium but a house and its lot, which puts the weight of the file back on the chain of title to the land: you climb through the deeds to the parcelación, the original subdivision that created the block, because those platting deeds registered conditions, setbacks and easements that still bind and that are invisible from the street. There is no building manager to issue a paz y salvo, a no-arrears certificate, and no assembly to settle anything, so boundary questions with a neighbor are argued between private parties and what governs is the title and the survey, not a set of house rules. The counterparty is usually an old city family and, fairly often, a family company that owns the property: then you must decide whether to buy the real estate or the company's shares, two different transactions with different paperwork and different exposure, and request the certificado de existencia y representación, the corporate good-standing and signing-authority certificate, together with the resolution approving the sale. And because the neighborhood is fully built out, any construction is permitted on an already developed lot, with neighbors entitled to take part in the proceeding.
What is specific to Castillogrande
The residential tip of the peninsula: lower and quieter than Bocagrande, facing the bay, with little street retail. Houses and low-rise buildings sit alongside new towers, and single-family homes still exist. It is a dead end: access is through Bocagrande with no through road at the far tip, which keeps it free of passing traffic.
- whether the property faces the bay or the open sea, because the swell, the smell and the façade upkeep are not comparable
- what building height the rules allow on the lot, which is not uniform across the peninsula and is the first fact omitted when a lot is sold
- how ground stability was addressed, given this is land reclaimed from the sea, and what the soil study for the building says
What to verify, step by step
- Ask for the complete appraisal report rather than the summary page: it has to name the signer, the perito's registration, the date and the method used.
- Check the appraiser against the open register kept by the Lonja de Propiedad Raíz de Bolívar, which can be consulted from abroad.
- Compare the area, boundaries and identification of the property in the appraisal against the IGAC cadastral record and the certificado de tradición y libertad, the registry history of the property.
- Go through the items specific to houses in gated condominios that the appraiser should have had in front of him: where the house's área privada ends and the common area begins, because garden, perimeter wall and front setback are not always the owner's; what the reglamento imposes on façade, extensions and fencing, which is the first thing a buyer wants to change and whether the internal roads, water line and treatment plant belong to the condominio or were handed over to the Distrito, since that decides who repairs them.
- Add what the sector itself forces you to check in Castillogrande: whether the property faces the bay or the open sea, because the swell, the smell and the façade upkeep are not comparable; what building height the rules allow on the lot, which is not uniform across the peninsula and is the first fact omitted when a lot is sold and how ground stability was addressed, given this is land reclaimed from the sea, and what the soil study for the building says.
- If there will be a mortgage, ask the lender which appraisal it requires and confirm with the Superintendencia Financiera that the institution is supervised before handing over documents or funds.
Mistakes that cost money
- Treating the seller's appraisal as neutral. The seller paid for it and it was written to support the asking figure; still ask for it, but read who commissioned it.
- Asking the appraiser for a number instead of the report. What lets you argue about value are the assumptions and the comparables, not the conclusion.
- Assuming the appraisal replaces a title search. The perito values the property; he does not establish who may sell it.
Frequently asked questions
- Can I commission my own appraisal of a house in a gated condominio without being in Cartagena?
- Yes. The perito needs access to the property and its documents, not the buyer's presence; the signed report can be delivered by email.
- Why is the lender's appraisal below the asking price?
- Because it measures the institution's collateral, not the negotiation between the parties. They are two documents with different purposes and it is worth having both.
- Is the avalúo catastral useful for negotiating?
- It is useful for understanding the base of the impuesto predial, which is what IGAC and the District publish. For market value you order an appraisal from a registered perito.
