Just received this which is about right:

"Since my house is paid for I have no rent or payment.
Consequently I can live comfortably on about US$800 per month.
Electric golf cart = no gasoline.
Electric bill = BZ$120 per month
Water= BZ$22.55 per month
Cable = BZ$40. per month
Phone/DSL = BZ$180- BZ$200 per month"

Add rent $500 to $1,000us and food and $2,000 would be about right for one person.
