HI I am from Decatur, IL!
Housing is cheap around here depending on what you want in a home. If a country home, it is expensive LOL! However there are some one acre older homes around here priced from $40 to 60 thousand dollars. Rent is average around $800 to 1500 a month if you can find one.
Decatur is safe in certain areas. In the poor areas or housing projects, it is questionable and crimes are commonplace. Just about in every city you go to you are bound ot have some. In our area, it is pretty safe in the Elms and there are some rental homes in my area but some landlords are not fond of chickens. Ask first before acquiring some chickens.
Ecomony is ok but jobs are strong in the resturaunt and big businesses like ADM, Staley are pretty good. Caterpillar is questionable since some of my relatives have not been called back to work yet after being laid off for two months. It comes and goes like spurts. Xmas is a good time to looking for some jobs. It all depends on what you are looking for. The medical field jobs are great around here and always the need for nurses, office clerks, etc. and more doctors.
So are you planning on living in Decatur or living outside of Decatur?
