World-class destinations like Los Cabos, San Miguel de Allende, Puerto Vallarta, and the Riviera Maya consistently attract international home buyers and investors. However, when you decide to sell, Mexico’s Capital Gains Tax (Impuesto Sobre la Renta or ISR) can take a significant bite out of your net profit if you do not plan ahead.
