Beyond the sticker price, a Sisal purchase carries a predictable set of closing costs and taxes, and budgeting for them accurately keeps your beach dream on track.
Why Closing Costs Deserve a Line in Your Budget
Many foreign buyers focus entirely on the purchase price and are surprised at closing to find several additional line items. In Yucatán, total closing costs for the buyer typically run in the range of 5 to 8 percent of the property value, and coastal purchases in Sisal add the cost of establishing a fideicomiso bank trust. These figures are approximate and illustrative, as of 2026; the exact total depends on property value and the professionals you engage. Planning for them up front prevents unpleasant surprises on signing day.
ISAI: The Property Acquisition Tax
The largest single tax the buyer pays is the Impuesto Sobre Adquisición de Inmuebles (ISAI), the acquisition or transfer tax. In Yucatán this is commonly around 2 percent of the assessed value, though the precise rate and calculation are set by state and municipal rules and can vary. The notario calculates ISAI based on the higher of the sale price, the cadastral value, or the appraisal, and remits it to the authorities at closing.
Notario Fees
The notario público's fee compensates the office for verifying title, drafting the escritura, calculating taxes, and recording the deed. Fees are guided by a state tariff and scale with the property value, generally landing somewhere in the low single-digit percentage range. Because you typically choose the notario in Yucatán, ask several for written estimates so you can compare.
Registration at the RPP
Recording the deed at the Registro Público de la Propiedad carries a registration fee. This step is what makes your ownership official and searchable, so it is money well spent. The notario handles the filing and includes the fee in your closing statement.
Appraisal (Avalúo)
An official appraisal by a licensed perito valuador establishes the value used for tax calculations. The avalúo is a modest but mandatory cost, usually a few hundred US dollars depending on the property.
Fideicomiso Setup and Annual Fee
Because Sisal lies in the coastal restricted zone, foreign buyers hold their property through a bank trust. This adds two costs:
- A one-time setup cost, combining the SRE permit fee and the bank's establishment fee, typically in the low thousands of US dollars.
- An annual administration fee charged by the trustee bank, commonly a few hundred to roughly a thousand US dollars per year.
Request the specific bank's written fee schedule before committing, as these vary meaningfully between institutions.
The Seller's Tax: ISR (Capital Gains)
While the buyer pays ISAI, the seller owes Impuesto Sobre la Renta (ISR), Mexico's capital-gains tax on the profit from the sale. The notario calculates and withholds it. This matters to buyers for two reasons. First, an eager seller may try to under-declare the sale price on the deed to reduce their ISR; agreeing to this hurts you later, because your future capital gain will be calculated from that artificially low recorded value. Always record the true price. Second, understanding ISR now helps you plan for the day you eventually sell your Sisal home.
Planning Ahead for Your Own Future Sale
When you sell, you may qualify for a primary-residence exemption from ISR, but only under specific conditions, generally including tax residency, an RFC, official proof you lived in the home (utility bills in your name), and limits on how often the exemption is used. Foreign owners who never establish these do not qualify and face capital-gains tax on the full gain. Keeping receipts for major improvements is also valuable, because documented, invoiced upgrades can be added to your cost basis and reduce the taxable gain.
A Sample Cost Framework
To illustrate on an approximate basis for a coastal Sisal purchase (as of 2026, not a quote):
- ISAI acquisition tax: around 2 percent of value.
- Notario fees: roughly 1 to 2 percent.
- RPP registration and appraisal: a smaller fixed-plus-scaled amount.
- Fideicomiso setup: low thousands of US dollars, plus an annual fee thereafter.
Together these commonly total 5 to 8 percent of the purchase price for the buyer.
Practical Advice
Ask your notario for a written, itemized closing statement before signing so there are no surprises. Get the fideicomiso fee schedule directly from the bank. Insist on recording the true purchase price. Obtain your RFC early. With these steps, the costs of buying in Sisal become predictable numbers you can plan around, rather than a source of stress at the closing table.
