- Fideicomiso (bank trust)
- The instrument through which a foreign national acquires property in the restricted zone (50 km from the coast, 100 km from the border). A bank acts as trustee and the foreign buyer as beneficiary, with rights to use, enjoy and sell. It is not a lease and not a loan: it is the legal way to hold the property.
- Due diligence
- The review of everything backing a property before buying it: titles, liens, debts, permits, land use, ownership regime. It is the only part of the process you pay for in order NOT to buy.
- Public deed
- The document issued by a notary which, once recorded at the Public Property Registry, makes your ownership enforceable against anyone. A private contract, however well signed, does not replace the deed.
- Condominium regime
- The legal structure that splits a building or complex into private units and common areas. Setting it up is a formal act: without it, what you buy is not "unit 4B" but an undivided share of the whole property.
- Pre-sale
- Buying before it exists. NOM-247 requires the seller to display the full construction project and the scale model from promotion until handover, and to walk you through them on request.
