When and How to Refinance Your Mortgage in Mexico

If your mortgage is more than a couple of years old, you may be paying more than necessary. Refinancing — switching to a better rate, different product, or new lender — can save you thousands over the remaining term. This guide explains when refinancing makes sense and how to do it in Mexico.

When Refinancing Makes Sense

Refinancing typically makes sense when market rates have dropped significantly below your current rate, your financial profile has improved (higher income, better credit score, lower LTV through property appreciation), you want to switch from variable to fixed rate (or vice versa), you want to access equity for renovations or other purposes, or you want to change your loan term.

How Refinancing Works in Mexico

Portabilidad (mortgage portability) allows moving to a better-rate bank under the 2014 Financial Reform. Your current bank has the right to match. No prepayment penalty on INFONAVIT loans. Bank loans may have early repayment charges in the first 2-3 years. Compare using CAT (Costo Anual Total). CONDUSEF provides an online comparison tool. Given Mexican rates of 8-13%, even a 1-2% reduction saves hundreds of thousands of pesos

Calculating the Break-Even Point

The break-even point is how long the monthly savings take to exceed the costs of switching. Divide total switching costs by monthly savings to get the number of months. If you plan to stay longer than the break-even point, refinancing makes financial sense. Use our mortgage calculator to model the savings.

When NOT to Refinance

Refinancing does not always make sense. If the rate difference is small and switching costs are high, you may be better staying. If you are close to paying off the mortgage, the savings period is too short. If your property has decreased in value, your LTV may be worse, potentially increasing your rate.
