City Spotlight: Franklin, Brentwood & Spring Hill

County-wide averages only tell part of the story in a market this varied. Here's how three of Williamson County's most-searched cities compare right now:

Franklin Market Report 662 active

Avg. Price: $1,889,809 Cost/Sq Ft: $486 Avg. Size: 3,562 sq ft Avg. DOM: 69 days Under Contract: 319 Sold (6mo): 1,120

Franklin has by far the deepest inventory and sales volume of the three spotlighted cities, and is home to the county's single highest-priced active listing ($19,500,000). Sold homes averaged $1,307,624 against a $1,332,225 average list price — a sale-to-list ratio of about 98.2%. Data flag: a cluster of Franklin's higher-end listings show extreme cost-per-square-foot figures ($5,000–$6,600/sq ft) — almost certainly large land or farm parcels where land value dominates, not typical home comparables.

Brentwood Market Report 341 active

Avg. Price: $2,561,247 Cost/Sq Ft: $449 Avg. Size: 5,271 sq ft Avg. DOM: 60 days Under Contract: 111 Sold (6mo): 536

Brentwood carries the highest average price and largest typical home size of the three — nearly 33% above the countywide average, with active homes averaging over 5,200 square feet. Its sale-to-list ratio (~97.8%) tracks closely with the countywide figure.

Spring Hill Market Report 299 active

Avg. Price: $693,793 Cost/Sq Ft: $269 Avg. Size: 2,597 sq ft Avg. DOM: 50 days Under Contract: 131 Sold (6mo): 498

Spring Hill offers by far the most accessible pricing of the three — its average price is roughly a third of Brentwood's — making it a strong option for buyers who want Williamson County schools and location without Franklin- or Brentwood-level pricing. Its sale-to-list ratio (~98.8%) is the tightest of the three spotlighted cities.

Average List Price by City (Active Listings)
Brentwood$2,561,247
Williamson County (all)$1,933,110
Franklin$1,889,809
Spring Hill$693,793

Highest-Priced Active Listings

City Address Area List Price Beds Baths Living Sq Ft DOM
Franklin (countywide top) Old Charlotte Pike $19,500,000 10 15 23,138 19 days
Brentwood Old Hickory Blvd $10,000,000 6 9 11,682 0 days
Spring Hill Dr Robertson Rd $6,200,000 3 2 2,000 77 days

Note: the Spring Hill listing above is an outlier for that submarket (implying about $3,100/sq ft against a citywide average of $269) — almost certainly land-value driven, not typical of a Spring Hill home.
