Hello
I grew up in Madisonville, Kentucky....about an hour northeast of that area and I have a sister and her husband who now live in Kuttawa....just off I-24 exit 40 along Highway 62. They bought some land a long time ago near the lake and built a house back in the early 1990s there. So I have been through that area several times.
Job-wise....pretty much all the places you mentioned are small towns with not a whole lot going on....nearest hospital is in Paducah about 45 min to the west. No real big employers in the area...more mom/pop places....small businesses....but anything specific job wise just done know of anything. Would try looking west to Paducah. There is another poster here on the boards from the Cadiz area and he/she could help you out there as I am not familiar with housing, etc in Cadiz area.
Schools in most of Kentucky (outside of bigger cities) are county based school systems. Thus you have Lyon county schools based in Eddyville which serves Kuttawa and local area.
http://www.lyon.k12.ky.us/ One elementary, one middle, and one high school for the county.
Housing is pretty inexpensive...except for those few who are near the lakes. Some new home growth, but not a whole lot.
The land between the lakes region (as it is called) are man made lakes formed by the Tennessee Valley Authority for flood control and for generation of electricity. Thus dont tend to have homes, docks, etc along its shores that some lakes do. Fishing is excellent in the area. My sister loves to go to Grand River and Patty's restaurant which is a neat little shopping area.
Basically that area you are looking at is small towns, nice people, but not exactly a job mecca. 45 minute drive down I-24 to Paducah for shopping, dining, etc...or you can take I-24 to Nashville....about 2 - 2 1/2 hours or so.
I hope this helps some...
Dan
