Due Diligence on a $300K+ Purchase

The due diligence process for a COP 1.2B+ purchase in Medellín includes everything you'd do for a smaller transaction — certificado de tradición, closing costs, notaría process — plus several layers that only become critical at the luxury level. The additional complexity isn't about paranoia; it's about proportional risk management. A missed title lien on a COP 300M unit is painful. The same lien on a COP 2B unit is devastating.

This guide covers what changes above $300K — not the basics (which are covered on the hub site), but the additional checks and the sequencing discipline that luxury transactions demand.

The Visa-Eligible Deed: Where Most Luxury Buyers Make Their First Error

At the luxury level, your purchase almost certainly qualifies for a Colombian investor visa (M-visa, Type 3). The current threshold is 350 SMMLV, which in 2026 equals approximately COP 612,816,750. Units above approximately $300K USD clear this threshold comfortably. At COP 1.138B+ (650 SMMLV), you approach the permanent-residency (R-visa) threshold.

The first error most visa-eligible buyers make is allowing or encouraging a lower declared escritura value on the deed. This is common practice in Colombian real estate — declaring a value below the true transaction price reduces notarial fees, registration taxes, and the buyer's predial (property tax) base. At the mid-market level, it's a tax-efficiency play with moderate risk. At the visa-eligible level, it's a trap.

The visa application requires that the deed value (escritura) equal or exceed the SMMLV threshold. A unit purchased for COP 800M but declared at COP 550M — to save perhaps COP 3–5M in transaction costs — falls below the 350-SMMLV threshold and disqualifies your visa application entirely. The savings are trivial relative to the visa value. Don't let a broker or seller talk you into it.

Related: the foreign-investment registration (Registro de Inversión Extranjera) with the Banco de la República requires that the registered international wire amount match the declared deed value. Wire COP 800M but declare COP 550M, and you have a COP 250M gap that the central bank will flag. This creates both a tax liability and a repatriation problem when you sell.

The Correct Sequencing

At the luxury level, sequencing errors are more expensive and harder to reverse. The correct order — and the one that most buyers' lawyers will confirm if you ask them directly — is:

The critical discipline: steps 3 and 4 must happen before step 5. Wiring money after the deed is signed creates a temporal mismatch that complicates the investment registration. Signing the deed before registering the investment means the Banco de la República may question the sequence. Neither is fatal, but both create delays and paperwork that a correct sequence avoids entirely.

Luxury-Level Title Diligence

The standard estudio de títulos reviews the certificado de tradición — the property's ownership and encumbrance history as recorded at the Oficina de Instrumentos Públicos. At the mid-market level, a 10-year review is standard and usually sufficient. At the luxury level, go deeper.

The Lawyer Question

At the luxury level, your lawyer is the most important person in the transaction — more important than the broker, more important than the seller's agent, more important than the notary. The lawyer structures the promesa, runs the title study, coordinates the investment registration, and catches the problems that everyone else is incentivized to overlook.

The temptation is to use the cheapest option: the broker's recommended lawyer (who may prioritize the broker's deal-closing interest over your diligence interest), or a lawyer who charges COP 2–3M for a transaction that justifies COP 5–8M in legal fees. At the $300K+ level, legal fees represent 0.5–1% of the transaction value. This is not where you save money.

What to look for: a lawyer with specific experience in foreign-buyer transactions (the investment registration and visa implications are specialized knowledge), familiarity with upper-Poblado buildings (they'll know which developers have track records of construction disputes), and willingness to represent your interests exclusively (not the seller's lawyer, not a "we represent both sides" arrangement).

The Insurance Question Nobody Asks

Property insurance in Colombia is not mandatory for owned units (unlike mortgaged properties, where the bank requires it). Many foreign owners — especially at the luxury level — skip insurance entirely, reasoning that the building's PH covers common areas and that Medellín's earthquake risk feels abstract.

At COP 1.5B+, uninsured ownership is a significant financial exposure. A comprehensive policy covering earthquake, fire, water damage, and civil liability runs approximately 0.15–0.30% of the insured value annually — COP 3–6M/year on a COP 2B unit. That's roughly one month's admin fee for coverage that protects the single largest asset most foreign buyers own in Colombia.

The PH policy covers common areas (structure, elevators, shared spaces) but not your unit's interior — your finishes, your furniture, your improvements. If a water leak from the unit above destroys your COP 200M kitchen renovation, the PH policy doesn't cover your loss. Your own policy does.

Pre-Construction at the Luxury Level

If you're considering a pre-sale (sobre planos) luxury project, the diligence requirements add another layer: developer financial health, fiducia structure, and delivery-risk assessment.

The fiducia (trust) structure is where your cuota inicial (typically 30% of the purchase price) sits during construction. In a properly structured project, funds go into a fiducia inmobiliaria administered by an independent trust company — not directly to the developer. If the project fails, the fiducia returns your funds (minus administration fees). If the funds went directly to the developer and the project fails, recovery depends on the developer's solvency.

At the luxury level, pre-construction deposits can be COP 400–600M+. Verify the fiducia structure before you transfer anything. See the pre-construction fiducia guide on medellinrealestate.co for the full breakdown.

The Bottom Line

Due diligence at the $300K+ level isn't a different process from mid-market — it's the same process executed more thoroughly, with additional checks that are proportional to the higher stakes.

The three most expensive luxury-buyer errors, in order: (1) under-declaring the escritura value to save on transaction costs and losing visa eligibility; (2) skipping the investment registration and discovering the problem at resale when you can't repatriate; (3) not checking the PH financials and getting hit with a COP 50M+ cuota extraordinaria in year one.

All three are avoidable with a competent independent lawyer and the discipline to follow the correct sequence. The cost of doing it right is 1–2% of the transaction value. The cost of getting it wrong is losing the transaction value, your visa, or both.
