or your sons...but you can have a Mexican bank own it for you :)
From what I gather from some older friends of mine it's a hell'a nightmare to go through the process....
CAN FOREIGNERS REALLY OWN PROPERTY IN MEXICO?
Yes, Americans and other foreigners may obtain direct ownership of property in the interior of Mexico. However, under Mexican law, foreigners cannot own property outright within the restricted zone. Instead, a real estate trust must be set up to hold title for the foreigner. Since foreigners are not able to enter into contracts in buy real estate, they must have a bank act on their behalf, much as a trust is use to hold property for minors because they also can not contract. The following is a brief outline of the law regarding such trust, known as "fideicomisos", but potential buyers should always get advice and have all real estate transactions overview by a licensed Mexican attorney.
THE RESTRICTED ZONE AND "FIDEICOMISOS"
The law declares that the Mexican nation has original ownership to all land and water in Mexico, as well as minerals, salts, ore deposits, natural gas and oil; but that such ownership may be assigned to individuals.
The Mexican Constitution prohibits direct ownership of real estate by foreigners in what has come to be known as the "restricted zone." The restricted zone encompasses all land located within 100 kilometers (about 62 miles) of any Mexican border, and within 50 kilometers (about 31 miles) of any Mexican coastline. However, in order to permit foreign investment in these areas, the Mexican government created the "fideicomiso," (FEE-DAY-E-CO-ME-SO) which is, roughly translated, a real estate trust. Essentially, this type of trust is similar to trusts set up in the United States, but a Mexican bank must be designated as the trustee and, as such, has title to the property and is the owner of record. The Mexican Government created the "fideicomiso" to reconcile the problems involved in developing the restricted zone and to attract foreign capital. This enabled foreigners, as beneficiaries of the trusts, to enjoy unrestricted use of land located in the restricted zone without violating the law.
A "fideicomiso" is a trust agreement created for the benefit of a foreign buyer, executed between a Mexican bank and the seller of property in the restricted zone. Foreign buyers cannot own real estate in the restricted zone due to Constitutional restrictions. The bank acts on behalf of the foreign buyer, taking title to real property. The bank, as trustee, buys the property for the foreigner, then has a fiduciary obligation to follow instructions given by the foreigner who is the trust beneficiary. The trust beneficiary retains and enjoys all the rights of ownership while the bank holds title to the property. The foreigner is entitled to use, enjoy, and even sell the property that is held in trust at its market value to any eligible buyer.
