Mexico's Restricted Zone and the Fideicomiso: Beachfront Buying for Americans

Article 27 of the Mexican Constitution, adopted in 1917, established that foreigners cannot own real property within specified zones of national security importance: 100 kilometers from any international border, and 50 kilometers from the coastline. The rule reflected the post-revolutionary political context — Mexico had just emerged from a decade of civil war, had a long history of foreign interventions (American, French, British), and was not inclined to let foreign nationals own strategic coastal and border land. You can read the current version of Article 27 on the Mexican government's constitutional portal or a cleaner English translation via the Organization of American States.

The restricted zone covers almost every place an American would want to live. The entire Baja California peninsula is inside it (the peninsula is narrower than 100 km at most points and has coastline on both sides). All of Cancun, Playa del Carmen, Tulum, Cozumel, and the rest of the Riviera Maya sits inside the 50 km coastal band. Puerto Vallarta, Sayulita, Nuevo Vallarta, Bucerias, all of the Costalegre, Manzanillo, Ixtapa, Zihuatanejo, Acapulco — inside the restricted zone. Mazatlan, Rocky Point, La Paz, Los Cabos — all restricted. Even interior areas like San Miguel de Allende and Mexico City are outside the restricted zone, but if you want beach, you're buying restricted.

What the restricted zone does not mean is that foreigners cannot have property rights in those areas. It means that the form of those rights has to be the fideicomiso trust or the Mexican corporation (for commercial property), not direct fee-simple ownership. Mexico solved the Constitutional problem without amending the Constitution by inventing a trust structure where a Mexican bank legally holds title as trustee and the foreigner holds all the beneficial rights. This is the key point Americans often miss: the fideicomiso is not a lease, not a concession, not a long-term rental. It is a trust, and trust law in Mexico gives the beneficiary essentially every practical right of ownership. Brevitas' fideicomiso explainer and Baja Properties' detailed walkthrough both frame it correctly.

The legal authority for the structure is the Ley de Inversión Extranjera (Foreign Investment Law), administered by Mexico's Secretaría de Economía. The law was heavily revised in 1993 to make fideicomisos 50 years with automatic renewal, which eliminated the previous uncertainty about what happened at term-end and turned the structure into something functionally permanent.

A fideicomiso is a three-party legal structure: the settlor (fideicomitente, usually the seller), the trustee (fiduciario, a licensed Mexican bank), and the beneficiary (fideicomisario, the foreign buyer). When you buy a house in the restricted zone, the seller transfers legal title to a Mexican bank, which holds it in trust, and you are named as the primary beneficiary. The trust instrument — called an acta de fideicomiso — is recorded at the Public Registry of Property in the municipality where the property sits and is a matter of public record.

As the beneficiary, you have the right to:

• Occupy and use the property for any legal purpose — primary residence, vacation home, rental, even to run a business from the premises.
• Rent or lease the property to anyone, short-term or long-term, without the bank's permission.
• Mortgage the property through Mexican or foreign lenders (most Mexican banks will finance to foreign buyers secured against the fideicomiso).
• Sell the property to another foreigner (who takes over your trust beneficiary position) or to a Mexican citizen (who can take direct title and terminate the trust).
• Designate heirs who automatically inherit your beneficial interest on your death, avoiding Mexican probate (sucesión).
• Make improvements, demolish, rebuild — anything an owner would do.

What the bank does is essentially nothing, and that's the point. The trustee bank has a passive role: it holds title, it files annual reports to the Secretaría de Economía confirming the trust is still active, it processes documents when you direct it to (a sale, a transfer, a change of beneficiary), and it collects its annual fee. It cannot sell your property without your instruction. It cannot encumber it without your instruction. It cannot change the beneficiary without your instruction. It has no discretion. MexLaw's detailed trust breakdown and My Casa's 2025 fideicomiso guide walk through the mechanics.

The duration is 50 years, renewable for another 50 years on application, and renewable again indefinitely. In practice, a Mexican family owning property through a fideicomiso will simply roll the trust forward every 50 years. Your heirs inherit the beneficiary position and continue the trust. There is no scenario, under current law, where the trust expires and you lose the property — as long as the annual fees are paid and the trust is maintained. Caribe Luxury Homes and Overseas Dream Home both emphasize this permanence.

The closest US analog is a land trust, where a trustee holds title on behalf of a beneficiary and the beneficiary runs the property. The Mexican fideicomiso is more robust than most US land trusts because it's written into federal investment law and backed by a licensed bank with fiduciary obligations. The difference from a lease or a concession is that a lease is a use-right with a hard end date, while a fideicomiso is a renewable trust with an indefinite horizon.

Here's the total cost picture for a typical fideicomiso purchase, based on 2025-2026 data from Mexico Relocation Guide, TheLatinvestor's 2026 Mexico guide, and several bank fee schedules.

Setup costs (one-time, at closing):

• Fideicomiso establishment fee: $500-$1,500, paid to the trustee bank, depending on which bank you choose. Scotiabank, BBVA, Banorte, Actinver, CIBanco, and Monex all offer fideicomiso services. Fees vary.
• Secretaría de Economía permit: Around $1,500. This is the federal permission that must be issued before the trust can be created.
• Notary fees: 1-2% of the purchase price. In Mexico, a notario público is a high-level legal officer (not a US-style notary) who drafts the escritura pública — the deed — and certifies the transaction. Their fees are regulated but vary by state.
• Acquisition tax (Impuesto sobre Adquisición de Inmuebles, ISAI): 2-4% of the assessed value, depending on the state. Quintana Roo is around 2%, Baja California Sur is higher.
• Registration fees: 0.5-1% for recording at the Public Registry.
• Appraisal: $300-$800 for the mandatory avalúo.
• Title insurance (optional but recommended): 0.5-0.75% for a Stewart Title or First American policy. Most American buyers take it.

Add it all up and total closing costs run roughly 5-8% of the purchase price, on top of the price itself. On a $400,000 condo in Playa del Carmen that's $20,000-$32,000 at closing, all in.

Annual costs:

• Fideicomiso annual fee: $550-$1,000, paid to the trustee bank every year as long as the trust is active. Most banks bill once a year. Plalla's breakdown and Cabo La Estancia's guide use the same range.
• Property tax (predial): 0.1-0.3% of assessed value per year. Mexico's property tax is shockingly low — often less than $500 per year on a $500,000 property. This is the number that makes the rest of the math work for a lot of retirees.
• HOA/condo fees if applicable: Highly variable, usually $100-$400/month depending on amenities.
• Utilities and maintenance: Normal costs, cheaper than the US equivalent.

Over a 30-year holding period, the cumulative fideicomiso fees run $16,500-$30,000, which is real money but proportionally small compared to the property's appreciation in a hot market. Compare that to Costa Rica's 2.5% annual canon on a concession, which on the same $400,000 property would be $10,000 per year — and the fideicomiso looks like a bargain. We walk through the head-to-head in our Costa Rica maritime zone post if you're deciding between the two countries.

The process for buying a property through a fideicomiso takes 6-12 weeks from offer to closing in a normal transaction. Here's what actually happens:

Week 1: Offer and purchase agreement. You make an offer on a property, negotiate the price, and sign a promesa de compraventa — a preliminary purchase agreement — with an earnest money deposit (usually 5-10% of the price) held in escrow. The escrow should be with a neutral third party, not the seller's real estate company. US-based title companies like Stewart Title Mexico handle escrow for foreign buyers in most beach towns.

Week 2-4: Due diligence. Your lawyer (or the notario's office, depending on how you structure it) runs a title search at the Public Registry, confirms the seller has clean title, verifies property tax is current, checks for liens and encumbrances, confirms the property is properly zoned and legally permitted, and gets the physical survey (linderos) confirming the boundaries. This step catches most problems. Common issues: unresolved ejido (communal) land claims, incomplete title from subdivision developers, unpermitted additions, boundary disputes, and liens from unpaid utility bills. TaxesForExpats' 2026 Mexico guide and the Mexico Life restricted zone FAQ both cover the diligence checklist.

Week 4-6: Fideicomiso setup. Your lawyer applies to the Secretaría de Economía for the fideicomiso permit. You choose a trustee bank (usually based on a combination of fee, service reputation, and branch proximity). The bank runs its own KYC checks on you as the beneficiary. This usually takes 3-4 weeks and is the primary source of delay in a foreign purchase.

Week 6-8: Escritura preparation. The notario público drafts the escritura pública — the formal deed that transfers title to the trustee bank and names you as beneficiary. You or your legal representative reviews it. If you don't read Spanish, get a certified English translation; do not sign an escritura you don't understand.

Closing day: You (or a legal representative with power of attorney) appears at the notario's office with the purchase funds. The escritura is signed, the acquisition tax is paid, the trustee bank becomes the legal owner, and you become the fideicomiso beneficiary. The notario records the escritura at the Public Registry, and a few weeks later you receive your certified copy.

One thing Americans miss: you do not have to be physically present to close. If you grant a poder (power of attorney) to a trusted representative in Mexico, they can sign on your behalf. This is standard practice for buyers who don't want to fly down for closing. The poder must be notarized in the US, apostilled, and translated into Spanish. Our post on buying sight unseen abroad covers the remote-closing mechanics in detail, and we walk through the Mexico-specific process in the buying process Mexico guide.

Here's the part that surprises Americans and costs them thousands of dollars. Owning Mexican real estate through a fideicomiso creates three distinct sets of tax obligations — Mexican, US, and state — and they don't line up neatly.

Mexican taxes:

Annual property tax (predial) is paid to the municipality where the property sits. Rates are 0.1-0.3% of the cadastral value, which is usually well below the market value. Miss a year and penalties accumulate. SAT, Mexico's tax authority, handles federal taxes; predial is municipal.

Rental income is subject to Mexican income tax (ISR). Foreign owners who rent out their fideicomiso property must register with SAT, get an RFC (Mexican tax ID), file monthly VAT returns (IVA, 16% on rental income), and pay ISR on net rental income. The tax rules changed in 2022 to require Airbnb and other platforms to withhold ISR at source, which has made informal rental operation harder to sustain. Mexico Relocation Guide's rental tax breakdown is the clearest English summary.

Sale of the property triggers capital gains tax on the gain, payable in Mexico. Residents get exemptions for primary residence; foreign beneficiaries generally pay 25% on gross sale price or 35% on net gain, whichever is less. The calculation is complicated and the notario handling the sale withholds the tax at closing.

US taxes:

Here's where most Americans get tripped up. The IRS has historically taken the position that a fideicomiso is not a 'foreign trust' requiring Forms 3520 and 3520-A — this was formally resolved in IRS Revenue Ruling 2013-14, which clarified that a Mexican land trust where the foreign owner retains all beneficial rights is not treated as a foreign trust for US tax purposes. The Revenue Ruling is critical reading if you own or are buying a fideicomiso — it's the document that keeps you out of the foreign trust reporting regime.

What you do have to report:

• Rental income from the Mexican property on your US 1040, as foreign-source rental income. You can credit Mexican ISR paid against US tax on the same income via Form 1116 (Foreign Tax Credit).
• Sale of the property: capital gain or loss on your US return. You can credit Mexican capital gains tax paid.
• Form 8938 (Statement of Specified Foreign Financial Assets) may be required if the property is held by a foreign entity, but direct ownership of real estate — and a fideicomiso beneficiary interest — is generally not a reportable financial asset. Check with a CPA familiar with Mexican property.
• FBAR (FinCEN Form 114) reporting if you have a Mexican bank account with more than $10,000 aggregate at any time during the year. The property itself isn't reported; a Mexican checking account funded for HOA and utility payments is. See the FinCEN FBAR filing page.

Our post on avoiding double taxation on foreign property covers the foreign tax credit mechanics in detail, and capital gains on foreign property walks through the sale-side math.

There's a second legal structure for foreign ownership in the restricted zone: a Mexican corporation (sociedad anónima or S. de R.L. de C.V.). The Foreign Investment Law allows foreigners to own 100% of a Mexican corporation, and the corporation can own land anywhere in Mexico — including the restricted zone — as long as the land is used for 'non-residential' purposes. A rental business, a vacation rental, a hotel, a commercial building: all qualify as non-residential and can be held by a foreign-owned Mexican corporation.

The appeal is that the corporation can own land directly, no fideicomiso, no bank fees, no 50-year renewal. You set up the corporation, the corporation buys the property, you own 100% of the corporation.

The catch is that the corporation route is only legal if the property is actually used for commercial purposes. A house you live in as a primary residence does not qualify. If SAT or the Secretaría de Economía determines that a corporation is holding residential property for the owner's personal use, the structure can be challenged, the property transfer can be invalidated, and the owner can be required to re-establish the holding through a fideicomiso or sell to a Mexican national. MexLaw and Nuhome Mexico both flag this.

The corporation also comes with significant compliance overhead: monthly SAT filings, annual corporate returns, a Mexican accountant, a Mexican corporate address, and — for US owners — Form 5471 reporting to the IRS for ownership of a foreign corporation (a controlled foreign corporation, or CFC, if you own more than 50%). Form 5471 penalties for non-filing start at $10,000 per year, and ignoring it is one of the most expensive mistakes a US foreign investor can make. See IRS Form 5471 instructions.

For a pure personal residence — the house you live in, or the vacation home you use yourself 80% of the time and rent 20% — the fideicomiso is the right structure. For a full commercial rental operation with three or more units, a hotel, or a true business property, the corporation may make sense. Anything in between is a judgment call that needs a Mexican tax attorney, not a real estate agent, and a US CPA familiar with CFC reporting.

Peer experience on fideicomisos is mostly positive — the structure has been around for 50 years, millions of foreigners have used it, and the horror stories are overwhelmingly about bad title due diligence or sketchy developers, not about the fideicomiso itself. A few threads worth reading:

r/expats, 'Fideicomiso experience in Mexico' has multiple commenters confirming the process is routine and the annual fees are in the $500-$900 range. r/mexicoexpats, 'Buying beach property as an American' has a detailed walkthrough of a Tulum purchase. r/Mexico, 'Americans asking about fideicomiso' has Mexican locals explaining the history and the practical reality. r/AmerExit, 'Mexico beach retirement' covers the broader retirement picture including the fideicomiso math. And r/ExpatFIRE, 'Puerto Vallarta property through fideicomiso' has a thorough multi-comment discussion of the costs and the exit plan.

The consistent advice from experienced buyers is: use a notario público referred by someone you trust (not the seller's notario), use a bilingual real estate lawyer independent of the developer, get title insurance from Stewart Title or First American, and don't be in a rush. The fideicomiso itself is the easy part — it's the underlying title and the seller's diligence that create problems. Our post on finding a bilingual real estate lawyer abroad and buying sight unseen abroad both apply directly to Mexico.

The blunt summary: the fideicomiso is the most foreigner-friendly beachfront ownership structure in Latin America. It is not a lease, not a concession, not a workaround — it is real, legally robust, renewable in perpetuity, inheritable, mortgageable, and clearly blessed by Mexican federal law and US tax law. The Costa Rica and Philippines approaches both require you to give up something meaningful (ownership, control, or both). Mexico's approach gives you everything a fee-simple owner has, with a modest annual bank fee and a one-time setup cost. For Americans who want beachfront in Latin America, Mexico remains the easiest jurisdiction by a wide margin.
