Probably the biggest thing is to make sure you land leaches,(or perks) ok. Some of the clay or rocky soils in parts of Alabama won't. Check your local codes.
This. Any offer you make should be contingent on results of perc testing. Not only could the soil not perc at all, it might require a huge amount of field line that could be really expensive. Perc ability depends on type of soil plus the amount of slope to the lot.
You might put some yeast down to start the septic going, but shouldn't need anything after that at all. Don't put junk chemicals in your holding tank.
Do be sure to dump your black tank followed by gray and a good flush every week, and leave a little water in the black tank to keep any remaining solids from drying up.
