For many foreign buyers, purchasing real estate in Mexico is a dream come true. However, one often-overlooked risk can turn that dream into a financial headache: currency fluctuation. When buyers agree to purchase property in pesos but fund the purchase in another currency-such as U.S. or Canadian dollars-they expose themselves to the unpredictable swings of the foreign exchange market. These fluctuations can have a significant impact on the final cost of a home, sometimes adding tens of thousands of dollars to the original price.
