Buyer vs Seller: Who Pays Closing Costs in Mexico Real Estate?

In Mexican real estate, both the buyer and the seller pay closing costs, but on completely different items. The buyer pays the acquisition tax (ISABI), notary fees, registration, and the bank trust setup, typically totaling 5 to 8 percent of the purchase price. The seller pays the capital gains tax (ISR) on any profit and the real estate commission. Each side settles its own costs at the deed signing through the notary, so no one party is surprised by the other's obligations.

For American buyers from the San Diego area, this split is broadly similar in spirit to the United States, though the specific taxes and the bank-trust requirement for coastal property are unique to Mexico. Here is the clear breakdown.

What the buyer pays

As the buyer of a Baja oceanfront condo, you are responsible for the costs of acquiring and registering the property:

• ISABI acquisition tax: roughly 2 to 3 percent of the assessed value, the single largest line item.
• Notary fees: the notary acts as a state-appointed fiscal officer; fees are tiered to the property value.
• Public Registry registration: to record the new deed.
• Fideicomiso (bank trust): setup fee plus the first annual fee, since foreigners hold coastal property within the 50 km restricted zone through a 50-year renewable trust.
• Appraisal, certificates, and permits: including the foreign-affairs permit for the trust.

Together these commonly land in the 5 to 8 percent range. On a residence starting at around half a million USD at our El Sauzal development, this is a predictable, budgetable figure your notary itemizes in advance.

What the seller pays

The seller's costs are tied to profit and to selling the property:

• ISR capital gains tax: withheld by the notary on the inflation-adjusted gain, after deductions.
• Real estate commission: customarily around 5 to 7 percent of the sale price plus applicable tax, paid by the seller.
• Document preparation: costs to assemble the deed, certificates, and any payoff of liens.

Because ISR can be reduced through inflation adjustment and documented improvements, sellers who kept good records pay less. This is covered in depth across our investment resources.

Why the buyer carries most of the closing costs

In Mexico, the convention is that the party acquiring the asset bears the costs of acquisition and registration, which is why the buyer pays the larger share of closing costs. The seller, by contrast, bears the tax on the gain they realized and the commission for the sale. This division is well established and handled cleanly by the notary, who collects each party's obligations from their respective funds at closing.

The notary's central role

Unlike a US escrow company, the Mexican notario público is a specialized attorney appointed by the state who validates the transaction, calculates and collects taxes for both sides, and registers the deed. This institutional structure is part of what makes Mexican closings transparent: the same official computes the buyer's ISABI and the seller's ISR, ensuring both are correct and remitted to the authorities.

Can the split be negotiated?

The customary division above is the norm, but specific items can sometimes be negotiated between parties, for example, who covers certain certificate or appraisal fees. In a new-development purchase, the developer typically presents a clear, standard cost structure so you know exactly what you owe with no ambiguity. Always ask for a written, itemized estimate before committing.

How this compares to a US closing

For buyers from the San Diego area, the structure feels familiar in spirit but differs in the details. In the United States, escrow and title companies coordinate the closing; in Mexico, the notary plays that central role with even broader fiscal authority. The customary split, buyer covers acquisition costs, seller covers gain and commission, mirrors common US practice. The notable Mexican additions are the fideicomiso for coastal property and the ISABI acquisition tax, both predictable and handled openly. There is no surprise junk-fee culture; the notary's accounting is itemized and official.

Why a documented purchase protects both sides

When the transaction is well documented, with a clean deed, formal invoices, and a proper appraisal, both buyer and seller benefit. The buyer gets clear title and a solid cost basis for the future; the seller has the records needed to claim deductions and minimize ISR. Buying new in a structured development means this documentation exists from day one, which is one reason pre-construction and newly built coastal residences are attractive to buyers who think long term about both ownership and eventual resale.
