Property Appraisal in Mexico: Types, Costs and When You Need One

A property appraisal (avalúo inmobiliario) is a technical opinion that determines the value of a property. You need one to buy with a mortgage, calculate taxes, sell at a fair price or divide an inheritance. But not all appraisals are the same: each type has its own purpose, cost and authorized professional. In this guide we explain the types, approximate costs and when you need each one.

What is a property appraisal?

It is a document prepared by an authorized appraiser (perito valuador) who estimates the value of a property using recognized methodologies: market comparison, replacement cost and income capitalization. It takes into account location, land and construction area, age, condition, materials and surroundings. The result is a substantiated value, useful for official procedures and financial decisions.

Types of appraisal

The bank appraisal is usually the strictest because the lender wants to secure its collateral; the tax appraisal is used for the ISR and the ISAI; and the cadastral appraisal feeds into the calculation of the predial.

How much an appraisal costs

The cost depends on the property's value, its location and the type of appraisal. Many appraisers charge a percentage of the value—often between 0.1% and 0.5%—or a base fee with increases depending on the amount. For mid-value homes, it commonly runs to a few thousand pesos.

When you need one

If your goal is simply to get a sense of the price in order to sell or buy, you can start with a market estimate and save the formal appraisal for when the paperwork begins.

Who can perform it

Officially valid appraisals must be prepared by authorized appraisers (peritos valuadores): accredited valuation units, corredores públicos (licensed public brokers), credit institutions or professionals registered with the competent authorities. For bank procedures, the institution usually requires an appraiser from its own authorized panel. Always verify that the appraiser is accredited for the purpose you need, because an appraisal done by someone without authorization will not be accepted.

Frequently asked questions

How long does an appraisal take?

Generally between a few days and a week, depending on the appraiser's schedule and the type of property. It includes an in-person visit to inspect the property and the preparation of the report.

Can a bank appraisal be used to calculate taxes?

Not always. Each procedure may require an appraisal with specific format and requirements. A bank appraisal is designed for the loan; for the ISR or the ISAI, the notario público may require a tax appraisal. Confirm the type you need before hiring one.

How long is an appraisal valid?

Appraisals have a limited validity, often a few months, because the market and the property's condition change. If your procedure is delayed, you may need to update it.

Can I use an appraisal to negotiate the price?

Yes. A documented commercial appraisal is a strong argument in negotiations, both for a buyer who wants to justify an offer and for a seller who is holding firm on a price. Combine it with real market comparables.
