Deep Dive: Each State
South Carolina (SC)
Tax reality
South Carolina top income tax is 6.2% (being reduced to 5.75% over time) and property tax averages ~0.57%. Combined effective tax is moderate. The real cost is rising property insurance — coastal homeowners face 15-25% annual increases due to hurricane risk.
Top cities (2 tracked)
Top drawbacks
- ✕Hurricane/flood risk is real in the Lowcountry — Katrina, Matthew, Florence, Ian all caused significant damage. "Sunny day flooding" in Charleston happens 3-5 times/year now (king tide + sea level rise), closing streets and roads with no storm.
- ✕Extreme summer heat and humidity — July-August regularly hit 92°F+ with 75%+ humidity, making outdoor activity miserable. Heat index routinely 100°F+. This is worse than Alabama due to coastal moisture.
- ✕Insurance costs are spiking coastal — homeowners insurance increased 15-25%+ annually in Charleston area. Flood insurance is separate and expensive. Some insurers are exiting the state entirely.
District of Columbia (DC)
Tax reality
DC has 10.75% top income tax (highest in the nation) PLUS you pay federal taxes — no local alternative. A $150K earner pays ~$30K in combined federal + DC income tax. The tradeoff: recession-proof federal job market, world-class walkability, and no need for a car (saving $600+/month).
Top cities (1 tracked)
Top drawbacks
- ✕Taxation is punishing — 10.75% local income tax combined with federal income tax means high earners pay 37-50% marginal rates. Capital gains tax applies at full income tax rate (not preferential), making real estate sales and investments expensive. This is the highest combined rate in the US.
- ✕No Congressional representation — DC has a Non-Voting Delegate but cannot pass laws without Congressional approval. Congress controls DC's budget. This is frustrating on principle and practically limits local autonomy.
- ✕Summer humidity is extreme — June-August average 90°F+ with 75%+ humidity, making heat index feel 100-108°F. Outdoor activity collapses. This is worse than the South because of the Potomac humidity.
