Ask three people what your Baja home is worth and you might get three different numbers, all of them technically correct. Mexico attaches more than one kind of value to a property, and knowing which is which keeps you out of trouble.
The catastral value
This is the government’s assessed value, the basis for your predial, the annual property tax. It is almost always far below market value, which is why property tax in Baja California Sur feels so pleasantly low to Americans. Useful for the tax office. Useless for knowing what your home would actually sell for.
The commercial value
This is market value, what a willing buyer would pay a willing seller today. It comes from a formal avalúo comercial prepared by a licensed appraiser using verified comparable sales, the condition of the property, and local conditions. This is the number that matters for a sale, a loan, an insurance claim, a divorce, or a court case.
The recorded value
This is the value written into the deed at the transaction, which drives your acquisition tax and, later, your capital gains. It should reflect reality. When it does not, usually because someone recorded a low number to save on tax at purchase, it comes back to bite at sale time.
Why owners get burned
People assume the low catastral number is “the value” of their home. Then they need to insure it, settle an estate, or defend a value in a U.S. court, and that low number is worse than useless. Each purpose needs the right value, prepared the right way. A court will not accept a tax-assessment figure as fair market value, and neither will an insurer writing a real check.
If you are not sure which value you actually need, that is a two-minute conversation worth having before you need it.
