Should You Move from Kentucky to Tennessee?
On paper, moving from Kentucky to Tennessee would save $3,500/year on a $100K salary, or $17,500 over 5 years. But relocation involves real costs: moving expenses, potentially buying/selling a home, changing jobs, and adjusting to a new community.
The $3,500/year savings is meaningful but probably not enough to justify a move on its own. However, combined with other factors like career growth, lifestyle preferences, or family proximity, it could tip the scale.
