The suburbs of Iowa is nice. No crime and cheap houses. Very little of work to be found though. Places like South Carolina has really cheap houses on plenty of land but outside of the major towns it looks like something close to the movie Deliverance. Actually there are many places in America that are safe.
Places like the Dominican republic and Thailand you are a major target for crime if you are an American. Staying in the resort hotels gives you a false sense that the place is safe. Journey out into the town at night. You might as well paint a bulls eye on your back.
There is one country outside of the US that I would move to right now if I could. Gorgeous country, cheap houses, no crime, friendly people, and hot women. I wouldn't tell a getbigger where it is for a million dollars.
