From Arizona to the Yucatan in Mexico, there are numerous gorgeous places that you can stay worldwide - for FREE - in return for some caretaking, housesitting, pet sitting, lawnmowing, and/or other duties. As a caretaker/housesitter, you can easily travel and live (or work) in many exotic places: mountain, lake, city, rural… and live like a local for anything from a few days to a couple of years.
