What is the SRE permit

The SRE permit (technically: "Permiso de la Secretaría de Relaciones Exteriores para adquirir bienes inmuebles") is an authorization issued by Mexico's Foreign Affairs Ministry (SRE — Secretaría de Relaciones Exteriores) that allows a foreign person or foreign corporation to acquire real estate inside the restricted zone via a fideicomiso.

Without this permit, the bank cannot set up the fideicomiso, the notario cannot script the deed, and the property cannot legally be transferred to the foreign buyer.

Timeline and cost

Application fee (derechos)~$8,500 MXN (~$500 USD)

What happens if the permit expires

If you don't close within 180 days, the SRE permit expires and you have to re-apply (pay derechos again, wait 4-8 weeks again). Plan your closing timeline carefully — the permit clock starts the day SRE issues, not the day you receive it.

The "calvo clause"

The SRE permit includes a mandatory "calvo clause" — you agree that as a foreigner you will not invoke your home country's government to intervene in disputes over the Mexican property. This is a constitutional requirement (Article 27) and is non-negotiable. It effectively means that if you have a dispute with the Mexican government over the property, you must resolve it in Mexican courts, not via diplomatic channels.
