Real Property Purchase Agreement Mexico (Contrato de Compraventa de Inmueble)

A Real Property Purchase Agreement Mexico (Contrato de Compraventa de Inmueble) is a formal written contract between a seller (vendedor) and a buyer (comprador) for the transfer of ownership (dominio) of real property (bien inmueble) located in Mexico, governed principally by the Código Civil Federal (CCF) Article 2248 and the applicable state civil code of the state where the property is located. Article 2248 CCF defines compraventa as the contract by which one party (the vendedor) obliges himself to transfer the ownership of a thing (dominio de una cosa) and the other party (comprador) obliges himself to pay a certain and determined price (precio cierto y determinado) for it. The Compraventa de Inmueble is one of the most significant legal transactions in Mexican civil law, both because of the economic value involved and because of the complex regulatory framework governing real property transfers.

For real property transactions in Mexico, Article 2317 of the Código Civil Federal and equivalent state provisions establish that conveyances of real property (transmisión de la propiedad inmueble) with a value exceeding the equivalent of 365 times the Unidad de Medida y Actualización (UMA) — for 2025 approximately $39,000 MXN — must be formalised through a escritura pública (public deed) executed before a Notario Público and registered with the Registro Público de la Propiedad (RPP) of the state where the property is located. Without notarial deed and RPP registration, the transfer of ownership is not enforceable against third parties (no es oponible a terceros) and the buyer's title remains at risk. The UMA is a unit of account established by the Ley para Determinar el Valor de la UMA (2016) and updated annually by the INEGI.

The Notario Público plays a mandatory and central role in real property transfers in Mexico. The notary verifies the seller's title (cadena de titulación), orders a certificate of no encumbrances (certificado de libertad de gravamen) from the Registro Público de la Propiedad to confirm the property is free of mortgages (hipotecas), liens (gravámenes), and attachments (embargos), and requests an updated cadastral valuation (avalúo catastral) from the relevant municipal authority. The notary also calculates and withholds the applicable taxes — Impuesto sobre Adquisición de Inmuebles (ISAI) on behalf of the buyer and ISR on capital gains on behalf of the seller — before registering the deed.

The constitutional foundation for real property rights in Mexico is Article 27 of the Constitución Política de los Estados Unidos Mexicanos, which establishes original national ownership of all territory and resources and imposes the zona restringida restrictions: foreigners cannot directly own real property within 50 kilometres of Mexico's coastlines or 100 kilometres of its international borders. Foreign buyers in these zones must acquire their interest through a fideicomiso bancario (bank trust/land trust) administered by a Mexican financial institution (institución fiduciaria) authorised by the Secretaría de Relaciones Exteriores (SRE) under the Ley de Inversión Extranjera. Outside the zona restringida, foreigners may directly own real property subject to the Calvo Clause — agreeing not to invoke the protection of their home country government in connection with the Mexican property.

Tax obligations in a Mexican real estate transaction are substantial. The buyer pays ISAI (Impuesto sobre Adquisición de Inmuebles) — a state and municipal acquisition tax ranging from 2% to 4% of the higher of the transaction price or the cadastral value (valor catastral), depending on the state. The seller pays ISR on capital gains under Articles 119 through 128 of the Ley del Impuesto sobre la Renta (LISR) — calculated on the difference between the sale price and the adjusted acquisition cost (costo de adquisición actualizado), after deducting notarial expenses and improvements. A critical exemption under Article 93 Section XIX LISR allows individuals to exempt ISR on gains from the sale of their principal residence (casa habitación) up to 700,000 UDIS (approximately $5.1 million MXN for 2025) once every three years, provided the property was their actual residence for at least two years. IVA (Impuesto al Valor Agregado) at 16% generally does not apply to residential property sales under LIVA Article 9 Section I, but may apply to commercial property sales between legal entities.

Mexico's public registry system for real property operates at the state level — each state maintains its own Registro Público de la Propiedad (RPP) governed by state law. After the Notario Público executes the escritura, the notary files the deed with the RPP for inscription in the folio real (electronic property record) — from this moment, the buyer's title is enforceable against the whole world (erga omnes) under the principle of publicidad registral. The Código Civil Federal Articles 3005 through 3046 establish the rules for registry priority and effects.

A Real Property Purchase Agreement Mexico is required for any transaction involving the transfer of ownership of real estate — whether residential (casa, departamento, terreno urbano), commercial (local comercial, oficina), industrial (nave industrial, bodega), or agricultural (terreno ejidal or parcela, subject to special rules under the Ley Agraria 1992).

A Contrato de Compraventa de Inmueble is the essential preliminary document when the parties wish to agree on the terms of the sale before executing the final escritura pública before the Notario Público — often called a contrato privado de compraventa or promesa de compraventa. This preliminary contract is binding on both parties under Articles 2248 and 2317 CCF, though ownership does not transfer until the escritura is executed and the deed registered with the Registro Público de la Propiedad.

The agreement is required when the buyer intends to finance the purchase through a crédito hipotecario (mortgage loan) from a bank (institución bancaria) regulated by the CNBV or through an INFONAVIT or FOVISSSTE housing credit — the mortgage lender requires a signed purchase agreement before approving the loan, and the notary needs the agreement to draft the mortgage deed (escritura de hipoteca) alongside the compraventa.

A Compraventa de Inmueble is also needed when buyers and sellers wish to document a purchase price different from the cadastral value (subvaluación) — a practice the SAT actively monitors through cross-referencing RFC-linked transactions. Under Article 76 of the Código Fiscal de la Federación, the SAT may challenge sale prices that differ significantly from comparable market values and reassess the applicable ISAI and ISR.

The agreement is required for transactions involving ejido land that has been converted to private property (dominio pleno) under the Ley Agraria — such parcels require verification of the certification and registration status through the Registro Agrario Nacional (RAN) and the Tribunal Agrario before a notarial compraventa can proceed.

Under Código Civil Federal art. 2248, art. 2317, Ley del Impuesto sobre la Renta arts. 119–128, and Ley del Impuesto al Valor Agregado art. 9, every real property transaction in Mexico should be documented by a licensed Notario Público who verifies title, orders encumbrance certificates, calculates taxes, and files the deed with the Registro Público de la Propiedad. The preliminary Contrato de Compraventa protects both parties during the period between agreement and notarial execution.

A valid Real Property Purchase Agreement Mexico under the Código Civil Federal and applicable state civil codes must contain the following essential elements:

Identification of Parties: Full legal name, RFC, CURP, official identity document number, and domicile of both the vendedor and comprador. For legal entities (personas morales), the company RFC, Registro Público de Comercio inscription, representative's name, and power of attorney reference must be included. Foreign buyers must provide their passport and Tarjeta de Residencia, and must confirm whether the property is in the zona restringida requiring fideicomiso bancario under Article 27 Constitución and Ley de Inversión Extranjera.

Property Identification: The complete legal description of the property — address (calle, número, colonia, municipio, estado, código postal), folio real (electronic registry record number) from the Registro Público de la Propiedad (RPP), clave catastral (cadastral key) from the Catastro Municipal, surface area (superficie en metros cuadrados), and any relevant annexes (bodegas, estacionamientos, áreas comunes in condominium units). Reference to the seller's title deed (escritura de adquisición) and RPP inscription number establishes the chain of title.

Purchase Price and Payment Structure: The agreed purchase price expressed in Mexican pesos (MXN) — IVA applies to commercial property between legal entities at 16% under LIVA, but residential sales are IVA-exempt under Article 9 Section I LIVA. The payment structure — down payment (enganche or anticipo), deferred balance (saldo diferido), and payment method (bank transfer via SPEI, mortgage proceeds) — must be stated precisely. Earnest money (arras or señal) paid at signing is typically deducted from the purchase price at closing.

Deadline for Escritura and Registry: The agreed deadline by which the parties will execute the escritura pública before the Notario Público and deliver possession (entrega de posesión y llaves). Mexican practice typically allows 30 to 90 days from preliminary agreement to notarial closing, depending on financing timelines and RPP registration backlogs.

Title Clearance Conditions: Conditions precedent (condiciones suspensivas) — including the seller's obligation to deliver the property free of encumbrances (libre de gravámenes), a clean certificate of no encumbrances (certificado de libertad de gravamen) from the RPP dated no more than 30 days before closing, payment of outstanding predial (municipal property tax) and water service bills (derechos de agua), and clearance of any ISABI (Mexico City) or equivalent municipal levies.

Tax Obligations: Allocation of tax costs between buyer and seller — ISAI paid by the buyer (2–4% depending on state), ISR on capital gains paid by the seller with the notary as withholding agent (retenedor) under LISR Article 126, notarial fees (honorarios notariales) allocated per agreement or local custom, and RPP registration fees (derechos registrales) paid by the buyer.

Physical Condition and Inventory: Statement of the property's physical condition at closing — whether sold as-is (en las condiciones en que se encuentra) or subject to repairs. For furnished properties, an inventory of included fixtures and appliances must be attached.

Default and Remedies: Consequences of default — if the seller defaults, the buyer is entitled to specific performance (cumplimiento forzoso) or rescission plus return of earnest money doubled (pena convencional) under Article 2117 CCF; if the buyer defaults, the seller may retain the earnest money as liquidated damages.
