source &, of course, for the ambiance. Heat is usually electric, natural gas, or propane. Some still heat w/wood, but less & less.
Covered front porches are certainly available, as you will see once you begin your housing search. Decks are popular, too.
You will find housing there is VERY affordable.
Cookeville has had a sewer system for many, many decades. It is a larger town than Crossville. However, if you choose to live outside town, as many do since the area offers such affordable & beautiful land, you many only find septic systems. Not a big problem, unless you abuse it. Don't flush anything other than toilet paper down it, use RidX occasionally & have it pumped if you think there is a problem. We have lived on a septic tank at our home for over 30 yrs in TN & never had the need to pump it. No problems whatsoever.
Please don't buy into the old worn out "Beverly Hillbilly's" images of Southern life. Sure, there are still some shacks way out in the country, but virtually EVERYONE has indoor plumbing....and we also wear shoes!
