The price of the house isn’t the only thing you’ll pay. Closing costs when buying a house in Mexico — the expenses to formalize the deal — usually fall between 4% and 8% of the property’s value. So it pays to know them from day one. That way you avoid last-minute shocks and budget with real numbers. Let’s break them down one by one.

What closing costs include

First, the essentials: closing groups several different items. Each has its logic and its owner. These are the main ones.

1. Property Acquisition Tax (ISAI)

This is the local tax paid when transferring the property. It varies by municipality and usually equals a percentage of the deal value. In Sinaloa the municipal government collects it.

2. Notary fees

Next, the notary. They give legal certainty to the sale, check that everything is in order and draft the deed. Their fees are regulated by tariff. To understand their role, see the Mexican National Notary Association.

3. Appraisal

Then the appraisal. An expert calculates the property’s value; the bank requires it when there’s a loan, and it serves as an official reference.

4. Public Registry filing

Next, registration. This step makes the property legally yours against third parties. Without it, your purchase isn’t protected.

5. Other possible costs

Finally, extras may add up: setting up the fideicomiso for foreigners, lien-free certificates and bank fees if you finance with a mortgage.

Who pays what

So who pays what? By custom, the buyer covers most closing costs: notary, ISAI and registration. The seller usually pays income tax on the gain, when it applies. In any case, this is clarified in writing before signing.

Final checklist before signing

Finally, the most important: review everything calmly. Before you sign, confirm that:

  • The property is lien-free (current certificate).
  • Property tax is paid and there are no utility debts.
  • The measurements and boundaries match the deed.
  • There are no maintenance-fee debts (in condos).
  • You have in writing what’s included in the sale (kitchen, closets, etc.).
  • You know the total amount of closing costs, not just the price.
  • You chose a trusted notary and reviewed the draft deed.

The final step, with peace of mind

When everything is verified, signing before the notary is quick and, above all, calm. And that calm is exactly the goal of planning well from the start.
