How do rental contracts and deposits work in Mexico in 2026?

The contrato de arrendamiento should identify landlord, tenant, property, residential use, rent, payment method (often SPEI), start date, term, renewal or notice rules, and deposit amount. Check who pays CFE, water, gas, building fees, routine maintenance, and repairs. Record pets, home working, guests, and subletting rules. Annual increase clauses are common; read the percentage or index language carefully before you celebrate a “cheap” first year.

Foreign tenants should expect passport and residency evidence on file: How to rent a home and Apply for residence. Keep Spanish clarity; if needed, get a trusted bilingual review before you sign. RFC can appear in longer formal files: Get an RFC.

Market practice for a security deposit is often about one month’s rent, paid with first month at signing. Some owners ask for more when you have no aval, especially as a foreigner.

An aval (fiador) is a person who co-signs and can be chased for unpaid amounts. A póliza jurídica is a legal-insurance style product that vets documents and supports enforcement for a fee often discussed as a fraction of one month’s rent: Rent without a guarantor. Neither replaces the need for a written lease. Handshake-only deals leave you exposed on deposit return and eviction timelines.

Do a joint exit walkthrough against entry photos. Lawful deductions target unpaid rent, charges, or damage beyond fair wear. Ask for written receipts for every payment: Open a bank account. Pressure to top up cash outside the contract is a red flag: Avoid rental scams.
