How the Mexican fideicomiso works: bank trust ownership for foreign buyers

If you are a foreign buyer eyeing a condo in Tulum, a beach house near Puerto Vallarta, or an apartment in a border city like Tijuana, you will run into one word again and again: fideicomiso. It sounds intimidating, and a surprising amount of what gets said about it online is wrong. This guide explains exactly what a fideicomiso is, what it costs, how long it takes, and what it does and does not give you.

Why the fideicomiso exists at all

Mexico’s Constitution (Article 27) prohibits foreigners from holding direct title to land within the restricted zone: 50 kilometers from any coastline and 100 kilometers from any land border. This is not a tax dodge or a loophole to close, it is constitutional law dating to 1917.

The fideicomiso, formalized under the 1973 Foreign Investment Law, is the legal instrument that lets you buy anyway. Instead of the property being titled directly in your name, a Mexican bank holds the title in trust on your behalf. You are the beneficiary of that trust, and the bank is the trustee (fiduciario).

Critically, this is not a lease and the bank does not own your property in any meaningful economic sense. As beneficiary you have the full bundle of ownership rights.

What you can actually do as beneficiary

The trust names you (and whomever you choose) as beneficiary, and that gives you the right to:

• Use and occupy the property however you like.
• Rent it out and keep all income.
• Renovate, build, or demolish within local regulations.
• Sell it to anyone, at any time, at any price you negotiate.
• Bequeath it to named substitute beneficiaries, bypassing Mexican probate.

The bank cannot sell, mortgage, or transfer your property without your written instruction. Its role is administrative and fiduciary, nothing more.

The numbers: setup and ongoing costs

Costs vary by bank and property value, but current market ranges are:

1. Trust setup (one-time): roughly USD 2,000 to 2,500, covering the bank’s establishment fee and the trust permit from the Ministry of Foreign Affairs (SRE).
2. SRE permit fee: a government charge folded into setup, typically a few hundred dollars.
3. Annual trust fee: roughly USD 600 to 800 per year, paid to the trustee bank for administering the trust. Higher-value or higher-tier banks can run more.
4. Notary and closing costs: separate from the trust itself, generally 5% to 8% of the purchase price, including the acquisition tax (ISABI), registration, and notary fees.

Budget the trust setup and the closing costs together, because they are paid at the same closing.

How long the trust lasts

A fideicomiso is granted for a 50-year term and is renewable for successive 50-year periods indefinitely. Renewal is a straightforward administrative filing, not a re-purchase, and should be handled before expiry. When you sell, the buyer either takes an assignment of your existing trust or sets up a new one.

Timeline: what to expect

From accepted offer to closing, a clean fideicomiso transaction usually takes 30 to 60 days. The main variables are:

• SRE permit issuance, which the notary requests on your behalf.
• Bank onboarding and KYC, since the trustee must vet you under anti-money-laundering rules.
• Title and lien search at the Public Registry.

Delays almost always trace back to incomplete documentation or a slow-moving seller, not the trust mechanism itself.

Common misconceptions worth killing

• “The bank can take my property.” No. The bank is a fiduciary bound by the trust deed; it acts only on your instruction.
• “I only own it for 50 years.” No. The 50-year term is the trust’s term and renews indefinitely. Your ownership is perpetual in practice.
• “A fideicomiso is a lease.” No. You hold full beneficial ownership, including the right to sell and inherit.
• “I should just use an LLC to avoid it.” A Mexican corporation can hold restricted-zone land directly, but that route carries corporate accounting, tax filings, and is generally intended for commercial or rental businesses, not a single vacation home. For most individual buyers the fideicomiso is cheaper and simpler.

Should you use a fideicomiso or a corporation?

A rough rule of thumb:

• One or two personal-use properties: the fideicomiso is almost always the right tool.
• A portfolio, active rental business, or development project: a Mexican corporation may make more sense, since it can hold multiple properties directly and deduct expenses, but it comes with monthly accounting and annual tax obligations.

This is a decision to make before you make an offer, because switching structures mid-transaction is costly.

Tax notes you should not ignore

Owning through a fideicomiso does not change your Mexican tax exposure:

• Annual property tax (predial) is low, often a few hundred dollars a year.
• On sale, capital gains (ISR) can reach up to 35% on the gain, though exemptions exist for primary residences that meet strict residency and documentation tests.
• Keep every facturado (officially invoiced) receipt for improvements. Undocumented cash work cannot be deducted from your gain and inflates your future tax bill.
