Predial is the annual municipal property tax an owner pays on real estate in Mexico. It is assessed on the cadastral value the municipality assigns to the property — not on market price — and every municipality sets its own rate, payment calendar and discounts.
In practice
If you are used to US or Canadian property tax bills, predial is usually the pleasant surprise in the file: it is famously low, because cadastral values sit far below commercial value. Municipalities almost always offer a discount for paying the full year early, in January or February, and vacant land is typically assessed lower than a finished house — the cadastre values land and construction separately.
There is no national figure worth quoting. Rate, cadastral value and discount are all set locally, so the only reliable number is the one on that specific property's bill. Ask for it before you buy.
Predial is also not the only annual line. Inside a gated community you add the maintenance fee — at Selvadentro, roughly 5 MXN per m² per month plus a reserve for long-term upkeep — and, if you buy through a fideicomiso, the bank's annual trust fee.
Watch out for
Unpaid predial: it travels with the property, not with the seller. Ask for the most recent paid receipt and confirm the cadastre shows no pending years before you sign. Your notario checks this at closing, but finding out there is late to renegotiate it.
