Sending Money from Mexico to Buy US Property: MXN to USD Guide

Mexican buyers have significant advantages over buyers from countries with strict capital controls: there is no annual quota limiting how much can be transferred abroad. A Mexican buyer can transfer USD $500,000 for a US property purchase in one wire. What matters is proper documentation and understanding the SAT reporting rules that apply on the Mexican side.

SAT Reporting and Mexican Tax Compliance

Mexican residents who transfer large sums abroad must comply with SAT (Servicio de Administracion Tributaria, Mexico's tax authority) reporting requirements. Key rules: (1) Banks must report transfers above MXN 100,000 in a single transaction to SAT. (2) Transfers above MXN 50,000 to foreign accounts may require documentation of the purpose. (3) Large transfers for real estate purchase should be documented with a purchase contract, title company wiring instructions, and proof of the property transaction. Proper documentation prevents SAT audit triggers and ensures the transfer is treated as a capital outflow (not as income to be reported) on the Mexican side.

The Transfer Process: SPEI to SWIFT

Mexican banks use SPEI (Sistema de Pagos Electronicos Interbancarios) for domestic electronic transfers. For international wires to the US: (1) Large Mexican banks (BBVA Mexico, Banorte, Banamex/Citibanamex, Santander Mexico) all offer international wire transfer services. (2) The MXN must first be converted to USD at the bank's exchange rate. (3) The USD wire is then sent via SWIFT to the US title company or attorney trust account. (4) Specialist currency services (Wise, OFX, XE) can also facilitate MXN to USD transfers at better exchange rates than retail banks.

Rates are indicative. Always compare at the time of transfer.

OFAC and US Compliance for Mexican Wire Transfers

US OFAC (Office of Foreign Assets Control) monitors all international wire transfers for sanctions compliance. Legitimate real estate purchases from Mexican nationals are not OFAC concerns. However, transfers should be from accounts in the buyer's own name (not third parties), and documentation should clearly identify the real estate purpose. Wire transfers from Mexico for US real estate are routine and handled by US title companies and attorneys thousands of times each year.

MXN/USD Currency Strategy

The peso has ranged from MXN 17 to MXN 22 per US dollar in the past three years. A 10% peso depreciation on a USD $400,000 purchase increases the cost by approximately MXN $700,000 at MXN 20 per dollar. Mexican buyers who want to lock a rate before closing can use a forward contract through a specialist currency service. The US-Mexico tax treaty prevents double taxation on any currency gains or losses related to the property purchase. See: Foreign National Mortgage Guide.

Frequently Asked Questions

Is there a limit on how much money a Mexican can transfer to buy US property?

No. Unlike China's SAFE $50,000 annual quota, Mexico has no annual cap on international capital transfers for real estate purchases. Large transfers will trigger SAT reporting and US AML review, but are not restricted in amount.

What documentation should accompany a large wire transfer from Mexico for US property?

Purchase contract, title company or attorney wiring instructions, and identification of the real estate purpose. Transfer should come from the buyer's own account, not a third party.

Which is better for MXN to USD conversion: Mexican bank or specialist service?

Specialist services (Wise, OFX, XE) typically offer 0.5-1% above interbank rate vs 2-4% for Mexican retail banks. On a USD $400,000 purchase, the difference can be USD $6,000 to $14,000.
