Two homes sit six minutes apart on the same Spring Hill map. Same square footage, same year built, same four bedrooms and quartz counters. One appraised at $712,000 last spring. The other appraised at $489,000. The buyers thought they were shopping the same city. They were not.
Spring Hill is one town with two counties inside it, and the median price you see on a portal is a single number stretched across a line that changes almost everything: which schools your child is zoned to, which tax rate you pay, which utility fills your water bill, and which comps an appraiser is legally obligated to use. If you are relocating and comparing Middle Tennessee suburbs, this is the number behind the number.
The number the portals show you
Over the three months ending May 2026, Spring Hill home prices sold for a median of about $542,000, up 5.3% compared to the same period a year earlier, with price per square foot at $240, down slightly, and homes averaging 65 days on the market. That is one snapshot. Zillow's home value index for Spring Hill sits at $495,048, down 5.4% year over year. A more recent MLS-sourced view from Impact Realty puts the average sale price at $439,518 for the June 12 through July 12, 2026 window, with days on market up 21.4% compared to the prior month.
Three sources, three different pictures. The spread is not a data problem. It is the county line hiding inside every summary statistic.
What the county line actually costs
Spring Hill's northern half sits in Williamson County. Its southern half sits in Maury County. The RealTracs MLS breakout is stark: Williamson County's median sale price of $715,000 runs 46% higher than Maury County's $490,000 median, a gap that reflects both higher Williamson land costs and the premium buyers place on Williamson County Schools.
| What you are comparing | Williamson County side | Maury County side |
|---|---|---|
| Recent median sale price | ~$715,000 | ~$490,000 |
| School district | Williamson County Schools | Maury County Public Schools |
| Property tax rate | Higher than Maury, lower than Davidson | Lowest of the three |
| Typical lot size | Often smaller in newer developments | Often larger, more acreage options |
Two things follow. First, the shape of the tax bill matters more than most relocation calculators show. Williamson County property taxes are lower than Davidson County but higher than Maury, and on a $650,000 home that difference compounds over a decade of ownership. Second, an automated valuation is only as good as its comparable sales pool. When a Zestimate on a Williamson-side home pulls comps from Maury sales a mile away, the estimate lands low. When the reverse happens, it lands high. The county line is where automated tools quietly fail.
The new-construction premium, priced honestly
The other number the median hides is the resale-versus-new-build gap. Across a rolling twelve-month window, the new construction versus resale pricing gap in Spring Hill runs $659,484 versus $536,000 at the median, and new construction commands a premium of roughly $123,000 over resale, though new builds arrive with builder warranties, modern floor plans, and energy-efficient systems. Of the 1,085 homes that closed in Spring Hill over the past twelve months, roughly 38% were new construction or to-be-built contracts and 62% were resale.
That premium is negotiable in ways resale is not. Right now Spring Hill builders are offering incentives to move inventory, rate buydowns of one to two points are common, and they have more flexibility than they advertise. A buyer working the resale market negotiates on price and repairs. A buyer working new construction negotiates on financing, closing costs, and upgrades, which often preserves the sticker price the builder needs for future comps while quietly saving you real money.
Where the money actually lands
Spring Hill's price distribution is wider than any single median can carry. The $400,000 to $500,000 range accounted for nearly 30% of all sales, and the segment above $700,000 is active and growing, driven largely by new construction in communities like August Park, Saddlewalk at June Lake, Sharp Manor, and Cedar Brooke, with 69 sales above $1 million reflecting appeal to luxury buyers who want space and newer homes without Franklin or Brentwood price tags.
At the entry level, first-time buyers gravitate toward the Maury side or the townhome market at Regent Homes' Harvest Point and Patterson Company's Arbor Valley. Move-up families weigh Hardins Landing against larger plans in Harvest Point. Rightsizers who want low-maintenance living look at Southern Springs by Del Webb, a 55+ community with homes from $515,000. Barton Hills, a thoughtfully planned new home community that will feature 256 homesites and sits roughly 20 miles south of downtown Franklin, is bringing a new wave of Maury-side inventory online.
Builder mix matters as much as community selection. D.R. Horton offers entry to mid-range homes with efficient layouts and strong value pricing, Regent Homes is popular for townhomes and lower price-point communities, West Homes is known for all-brick construction with stronger standard features, and Signature Homes is a higher-end semi-custom builder active at June Lake. Two homes at the same list price from two of those builders will not perform identically at resale. Standard specifications, structural allowances, and lot placement inside a phase all show up years later.
What to verify before you sign anything
Because Spring Hill spans two counties, the address on your contract does more work than buyers expect. One address can come with a different county tax structure, school assignment, and utility setup than another home minutes away, so lot-specific verification should happen early, and buyers should confirm the property's county, subdivision, lot number, utility providers, and any address-specific details tied to the home before committing. A short pre-signing list:
- Confirm the county assignment for the specific lot, not the subdivision, since some communities straddle the line.
- Verify school zoning by exact street address with the assigning district, since Spring Hill includes schools operated by both Maury County Public Schools and Williamson County Schools.
- Ask the builder for the utility provider list. Water, sewer, gas, and trash pickup do not follow one map here.
- Read the builder contract for change-order language, incentive expiration, and arbitration clauses. Builder contracts differ meaningfully from resale agreements.
- If you are building, confirm the contractor's license status. In Tennessee, a contractor's license is required before bidding, contracting, or offering a price on work of $25,000 or more.
- Budget for a realistic timeline. New home timelines average about eight months and can stretch much longer for custom builds, and Spring Hill permit review, inspections, and utility setup add local variance on top of that.
The other quiet shift worth planning around: inspection contingencies are back, and unlike 2022 most buyers are successfully negotiating inspection rights again. If you last shopped Spring Hill during the pandemic frenzy, this is a real change in leverage.
FAQ
Why does my Zestimate look wrong on a Spring Hill home? Because automated valuations pull comps by radius, not by county. A Zestimate pulling comparable sales from Maury County will undervalue a Williamson County home, and vice versa, and the $225,000 median price gap between the two counties means even homes on the same road can have dramatically different values depending on which side of the line they sit.
Is it a buyer's or seller's market right now? Softer than a year ago and uneven. Sale-price medians are up modestly year over year while Zillow's typical-value index is down and days on market are lengthening. Well-prepared listings still move. Overpriced ones sit and accumulate the kind of history that costs sellers more than a right-from-day-one price would have.
How much housing is under construction? Redfin shows 151 new homes for sale in Spring Hill at a median listing price of $529,000, with most homes on the market for 49 days and receiving one offer. That level of active new inventory is why builder incentives are real leverage right now.
Is the growth story still intact? The demand side has held. Spring Hill's estimated population reached 61,336 in 2025, up 21% from 2020, while Maury County reached 118,131, up 17% over the same period, and the city shows a 73.4% owner-occupied rate with a median owner-occupied home value of $493,800. This is a market of people staying put once they land, which is one reason resale inventory in the best-loved communities is thin.
The median is a headline. The county line is the story. If you are choosing between Spring Hill's two halves, or weighing a new build against a five-year-old resale two streets over, the right answer depends on numbers no portal shows in one place. That is the conversation to have before you write an offer, not after. Ashley Hicks works with relocating buyers on exactly these decisions across Williamson County and the Maury side of Spring Hill.
