Two bigger houses a few streets apart in Spring Hill can come with different county tax rates, different school districts and different prices per square foot. The county line runs right through the city, and it's easy to miss until you're comparing two houses side by side.
If you're moving up in Spring Hill, that line is the first thing I check.
Which county is a Spring Hill house in?
It depends on the address. Spring Hill sits in both Williamson County and Maury County, and the 37174 ZIP code covers both sides, so the ZIP won't tell you.
I settle the county before I pull a single comparable sale. Prices per square foot on the two sides of the line can be far apart, and mixing them gives you a number that's wrong for both.
How much do Spring Hill property taxes differ across the county line?
As of October 2026, Williamson County's rate for property inside Spring Hill is $1.27 per $100 of assessed value, and Maury County's 2026-27 rate is $1.369. The City of Spring Hill adds $0.739 on either side of the line.
| Taxing body | Rate per $100 of assessed value |
|---|---|
| Williamson County, inside Spring Hill | $1.27 |
| Maury County, 2026-27 | $1.369 |
| City of Spring Hill, both counties | $0.739 |
The rate is only half the math. Your bill also depends on the assessed value the county puts on the house, so I pull the tax history for the actual address and build it into your payment before we write an offer.
Where are the new-construction move-up homes in Spring Hill?
The newer communities I tour for move-ups in Spring Hill include August Park, Harvest Point, June Lake, Barton Hills, Arbor Valley and Southern Springs. Each has its own builders, plans and HOA, and they don't all sit on the same side of the county line.
August Park and June Lake are on the Williamson side. Harvest Point, Barton Hills, Arbor Valley and Southern Springs are on the Maury side. I still confirm the county and the school district for the exact address before we tour.
One thing to know before you visit a model home: most builders want your agent registered at your first visit to the sales office. Walk in alone and you may not be able to add representation later. Call me before you go, and I'll meet you there or register you ahead of time.
Ask about incentives tied to the builder's preferred lender, then compare that package against an outside lender's numbers. Sometimes it's the better deal. Sometimes it isn't.
What is the Spring Hill market doing right now?
In September 2026, 69 single-family homes closed in Spring Hill at a median sale price of $525,000, and the average closed home took 45 days to go under contract.
Based on information from Realtracs® for the period September 1, 2026 through September 30, 2026.
If your current home is in Spring Hill too, that's the market you're selling into. That median blends both counties, so I price your sale from closed sales in your own subdivision, on your own side of the line.
How do you sell your current home while you shop?
Pick a sequence before you tour: sell first, buy with a home-sale contingency, or buy first with bridge financing your lender approves. New construction can help here, because a home still being built gives your sale time to close. I lay out all three in my Thompson's Station move-up post.
Why have me handle both sides?
I've been licensed since 2013 and earned more than 950 five-star reviews across my career. I live next door in Thompson's Station, so Spring Hill's new communities are part of my own backyard.
What's the first step?
Send me the addresses or community names you're looking at. I'll tell you which county each one is in and what the tax picture looks like before you fall for a floor plan.

Property tax figures are the county and city rates published for the year shown and are for planning only. Your actual bill depends on the assessed value, any exemptions and the city or district the home sits in. Confirm with the county assessor or trustee and your tax professional before you rely on a number.
