One of the most frequent questions from international investors purchasing property in Los Cabos is why two distinct valuations often appear during closing: the Cadastral Appraisal (Avalúo Catastral) and the Commercial Appraisal (Avalúo Comercial). Understanding the clear legal distinction between these documents prevents closing surprises and protects your fiscal position.
What is a Cadastral Appraisal?
The Cadastral Appraisal is a statutory assessment mandated by the Baja California Sur Cadastral Law (Ley de Catastro del Estado de Baja California Sur). Its sole objective is to assign an official taxable baseline to the land and construction improvements based on standardized municipal unit values (tablas de valores unitarios de suelo y construcción).
This valuation is submitted directly to the Municipal Cadastral Office in San José del Cabo or Cabo San Lucas. The Notary Public uses this figure to calculate the 2% ISAI acquisition tax and municipal deed recording fees.
What is a Commercial Appraisal?
In contrast, a Commercial Appraisal determines the Fair Market Value of the real estate asset under prevailing market conditions. This rigorous analysis applies three recognized valuation methodologies:
- Market Approach (Sales Comparison): Analyzing recent verified transactions of comparable properties in master developments like Pedregal, Chileno Bay, or Puerto Los Cabos.
- Cost Approach (Replacement Cost): Estimating the physical cost to reconstruct identical luxury improvements today, factoring in high-end importation costs for finishes, minus physical depreciation.
- Income Capitalization Approach: Projecting net rental revenues for high-yield vacation rental villas or commercial leases.
“Never rely on listing portal asking prices as proof of value. Only a Perito Valuador’s certified commercial appraisal provides true legal backing accepted by banks, trusts, and courts.”
