We were long enough on the Pacific Coast of Mexico, so it is time to move close to the Caribbean Sea. Tulum, next on our list of best places to retire in Mexico is still waiting to establish itself properly as a retirement destination, but the rent prices are already ahead of that. As you can see, the city has the highest average apartment rent cost on the list. Still, your money will be well spent, since you will spend your days on some of the most beautiful beaches in the whole world.
