What is the cost of living in the Northern Mariana Islands?

There is no "consumer price index" or USDA food price comparisons for the Northern Marianas, which makes it hard to answer. Federal Employees get a pay differential similar to Hawaii. Food costs vary-- if you eat locally grown produce and lots of rice, you can eat cheap. If you eat "American style" -- Apples, Oranges, grapes, pasta... it will be significantly more expensive. The least expensive meat is 25#-33# boxes of chicken leg quarters, followed closely by pork. Milk is sold in UHT boxes of 1 quart or 1 liter, and are about 1.20-1.50 a liter/quart.

Significantly more expensive--- the cost of gasoline ($4.50 ish a gallon) and the cost of electricity. (double or triple your current power bill)

Rentals-- cost vary significantly. Quality varies significantly also.
