Williamson County, Tennessee is quietly one of the most remarkable counties in America by the numbers. Sixty percent of adults hold a bachelor's degree, among the highest of any county outside a major university town. Median household income runs well into six figures. Unemployment is 3.9%. The county leans Republican (62%) and sits at the southern edge of the Nashville metro. Franklin and Brentwood are its two best-known communities, and both have become national symbols of the Southern professional class relocation.

The Most Expensive Suburb You Have Never Heard Of

The median home price in Williamson County is $842,000. That is not a typo. That price, in a county with no state income tax and relatively low property taxes, means Williamson County has attracted a specific type of buyer: high earners who left California or the Northeast and were willing to pay Nashville-area prices to lock in their savings on state and federal taxes. Tennessee has no state income tax on wages, which for a household earning $300,000 or more represents $20,000 to $30,000 per year in savings.

What You Get for That Price

Winters average a high of 50°F, cold enough to feel like seasons, mild enough to avoid the brutal winters of Chicago or New York. Summers hit 84°F average highs. The county sits about 1-3 hours from the nearest mountains. Nashville is 30 minutes north. The county has some of the highest-rated public schools in Tennessee. All hazard risks (earthquake, hurricane, tornado, wildfire) are Very Low to Very Low. This is about as safe a county from natural disaster as exists in the United States.

Who This County Is For

Williamson County is not for everyone. The entry price is high and climbing. The cultural vibe is firmly suburban and conservative outside of Franklin's historic downtown. But for a specific profile, high earner, family-oriented, values safety and schools, willing to pay for it, it consistently ranks as one of the most desirable places to live in the South.
