I would be careful, even of Gringos!! We had a resident taking care of our house.... things were stolen (although returned when pressed), and then we found out that parties were held at our home..... NOT GOOD!
I know that there are some very honorable Gringo's as well as Belizians, but just be aware.... I had a total inventory of every item, even down to my clothing, and my toiletries that I left there- rather than taking them back and forth.
