Ahh - Tunica County, Mississippi is the cheapest.
I had to Google Map it - was surprised and enchanted by some of the interesting place names nearby:
- Hollywood
- Falcon
- Darling
- Barksdale (anyone named Avon should live there)
- Sledge
- Savage
- Alligator
- Modoc (after the Marvel baddie)?
- Bobo
-Askew
Sadly the crime rates are substantially above average for Mississippi or the US. Doubt I’d survive short term residency:
