Foreign buyers consistently underestimate the cost of closing a real estate transaction in Mexico. The purchase price is only the starting point. Between government taxes, notary fees, trust setup costs, permits, and legal counsel, closing costs for a coastal property in the restricted zone typically add 5-8% to the purchase price. Understanding each component—who pays it, what it covers, and when it is due—prevents the budget surprises that derail transactions or reduce returns on investment.
Why closing costs in Mexico differ from the North American experience
In the US and Canada, real estate transaction costs are well-documented, title insurance is standard, and buyer and seller obligations are governed by established practice. In Mexico, the framework is different in several important ways.
First, the notary system means that a licensed government-empowered official reviews every real estate transaction and calculates taxes before closing. The notary collects taxes on behalf of the government and is legally responsible for correct calculations. This eliminates some of the escrow complexity common in US transactions but adds notary professional fees.
Second, the bank trust requirement for foreign buyers in the restricted zone adds a layer of trust setup and ongoing fees that do not exist for direct ownership transactions.
Third, IVA (Mexico's 16% value-added tax) applies to most professional services—notary fees, legal counsel, and other services are charged at the IVA-inclusive rate.
Fourth, the cadastral appraisal system (cadastral appraisal) differs from property assessment in North America. The cadastral value may differ significantly from the market value, and the ISAI tax is calculated on the higher of the two.
The full closing cost breakdown for foreign buyers
ISAI—property transfer tax
The property acquisition tax (ISAI) is the principal transfer tax paid by the buyer. It is calculated as a percentage of the higher of the transaction price or the cadastral value (cadastral value) of the property as determined by the municipal assessor.
ISAI rates vary by state:
- Quintana Roo: Approximately 3% of the higher of sale price or cadastral value
- Jalisco (Puerto Vallarta): Approximately 2%
- Mexico City (CDMX): Approximately 4.5%
- Baja California Sur (Los Cabos): Approximately 2-3%
The ISAI is collected by the notary at closing and remitted to the state treasury. The buyer pays it—this is non-negotiable and cannot be shifted to the seller by agreement (the law designates the buyer as the responsible party).
For a USD 500,000 coastal property in Quintana Roo, ISAI at 3% equals approximately USD 15,000. This is typically the largest single closing cost item.
Notario fees
The Mexican notary public charges professional fees for drafting the deed, reviewing the legality of the transaction, calculating taxes, executing the deed, and registering it with the RPP. Notary fees in Quintana Roo typically range from 0.5% to 1.5% of the transaction value, depending on the complexity of the transaction and the notary's fee schedule. State laws set maximum fee tables, but actual fees vary.
For a USD 500,000 property, expect notary fees in the range of USD 2,500-7,500 plus IVA at 16%.
The notary also charges separate fees for the registry registration process. These are additional to the professional fee.
Cadastral appraisal (cadastral appraisal)
The notary requires an official appraisal conducted by an authorized appraiser. The appraisal establishes the cadastral value for ISAI calculation and for the deed. The appraisal fee typically ranges from USD 300 to 800 depending on the property.
SRE Permit
For foreigners acquiring restricted zone property through a bank trust, the Secretaría de Relaciones Exteriores (SRE) charges a government fee for the trust permit. The current SRE permit fee is approximately USD 1,600 (the exact amount is denominated in pesos and updated periodically). This fee is paid before the bank trust is established.
Bank trust trustee setup fee
The bank that will act as trustee charges a one-time setup fee for establishing the bank trust. This fee varies by bank and is negotiable for larger transactions. Typical setup fees range from USD 800 to USD 1,500. Compare fees among the major trustee banks (BBVA, Santander, Scotiabank, HSBC, and others active in the Quintana Roo market) before selecting a trustee.
Annual bank trust trustee fee
Once established, the bank trust incurs an annual administration fee payable to the trustee bank. This is an ongoing cost that continues for the life of the trust. Annual fees typically range from USD 600 to USD 1,200 per year, though some banks charge more for high-value properties or complex structures. This fee is often overlooked when buyers calculate their cost of ownership—over a 10-year holding period, it represents USD 6,000-12,000 in additional cost.
Legal counsel fees
Independent legal representation for the buyer is separate from the notary. Your attorney reviews the purchase agreement, conducts due diligence, coordinates the SRE permit, reviews the bank trust instrument, and attends the closing. Legal fees for a standard residential transaction in Quintana Roo typically range from USD 1,500 to 3,500 depending on complexity, plus IVA at 16%.
Translation and apostille
If you are executing powers of attorney or other documents in your home country for use in Mexico, those documents require notarization in your jurisdiction, apostille certification, and Spanish translation by a certified translator (perito traductor). Translation and apostille costs for a typical set of closing documents run USD 300-800.
RPP registry fees
The Registro Público de la Propiedad charges fees for registering the deed. These fees are set by state law and vary by transaction value. In Quintana Roo, RPP registration fees typically range from MXN 3,000 to MXN 8,000 depending on the property value.
Who pays what
Buyer pays: ISAI, notary fees (in practice, though negotiable), cadastral appraisal, SRE permit, bank trust setup and annual fees, their own legal counsel, and translation/apostille.
Seller pays: ISR on capital gains (seller's income tax on the gain from sale), commission to real estate agent (typically 5-6% in Mexico, sometimes split), and their own legal counsel if represented separately.
In practice, allocation of notary fees between buyer and seller is negotiable, and in new developments the developer sometimes contributes to closing costs as a sales incentive. Always confirm in writing who bears each cost before signing the purchase agreement.

Frequently asked questions
Is the notary's fee negotiable?
Notary fees are regulated by state law fee schedules that set maximum amounts. Within that range, notaries exercise some discretion. For complex transactions (multiple parties, bank trust, and ZOFEMAT complications), fees tend to be at the higher end. For straightforward transactions, there may be room to negotiate. Obtaining quotes from two notaries for comparison is reasonable practice.
Can closing costs be financed as part of a mortgage?
If you are financing the purchase through a Mexican bank, the lender may allow some closing costs to be included in the loan amount, but ISAI and notary fees are typically paid separately from loan proceeds at closing. Foreign buyers using home-country financing need to wire funds for the full purchase price plus closing costs to Mexico.
Why is ISAI calculated on the higher of the purchase price or cadastral value?
Mexican law uses the higher of the two values to prevent tax avoidance through artificially low declared sale prices. In the past, parties would declare a nominal sale price while the real consideration was paid informally. Taxing on the higher value closes this loophole. If the cadastral value exceeds the market price (uncommon but possible in rapidly declining markets), ISAI is still calculated on the cadastral value.
Do I pay IVA on the property purchase itself?
IVA (16%) generally does not apply to residential real estate sales between individuals. New construction sold by a developer may include IVA in the purchase price, and commercial property transactions are sometimes structured to include IVA. The treatment depends on whether the seller is a VAT registrant and whether the property is new construction or residential resale. Confirm with your attorney and the notary before closing.
What is the seller's capital gains tax exposure in Mexico?
The seller pays ISR on capital gains from the sale. The gain is calculated as the sale price minus the acquisition cost (indexed for inflation), minus allowable improvements (with invoices as documentation), minus selling expenses. The withholding rate applied by the notary is 25% of the gross sale price or a lesser amount under the alternate calculation method. Foreign sellers may have additional reporting obligations in their home country. Tax planning before listing the property can significantly reduce the seller's Mexican tax burden.
