Is Williamson County Really Worth the Price Premium? An Honest Look for Families Moving to Franklin and Brentwood

In short: yes, for most families the Williamson County premium buys real, measurable things: the schools, the market stability, and the resale demand that keeps values climbing. But it is not the right answer for every family, and the honest way to decide is to look at what the premium actually pays for, not at what the asking prices feel like. Here is that breakdown for Franklin, Brentwood, and the rest of Williamson County, based on current data.

Why everyone moving to Middle Tennessee asks this

It is the first question in nearly every relocation conversation I have, and it is everywhere in the online spaces where people moving to Middle Tennessee gather: on the r/movetonashville subreddit, in Nextdoor threads, in Facebook groups for Nashville transplants. Families look at listings in Franklin and Brentwood, see prices that roughly double Nashville's median, and ask whether they are paying for something real or just for a name.

The honest answer is layered. The premium is real, but it is not mysterious. It is mostly three things: schools that post some of the strongest results in Tennessee, a market that has held its value through every rate cycle in recent memory, and a resale pool of other families who want the same things you do. Let me walk through each one, then the trade-offs, because there are trade-offs.

What the premium actually buys: the schools

This is the biggest piece of the premium. Williamson County Schools finishes at or near the top of every meaningful ranking of Tennessee districts. Niche grades the district an A and ranks it the #4 best school district in Tennessee for 2026. SchoolDigger puts it #5 out of 139 districts, and Public School Review gives it a 10 out of 10, the top one percent of the state.

Those rankings are downstream of the actual numbers. About 72 percent of Williamson County students test proficient in math and about 70 percent in reading, against Tennessee state averages of roughly 34 percent and 37 percent. The class of 2025 posted the best average ACT composite in the state at 25.3, and 79 percent of graduates scored 21 or higher, the threshold for Tennessee's HOPE Scholarship.

The high schools carry the same pattern. Brentwood High School is rated A-plus on Niche and the #5 public high school in Tennessee, with roughly 84 percent of students taking Advanced Placement courses. Franklin High School is rated A and ranks #13 in the state, and it made history as Tennessee's first International Baccalaureate school. When a family tells me they are choosing Franklin "for the schools," the data says they are choosing something real.

To be fair, the contrast in the same rankings matters too. Metro Nashville Public Schools grades at a B-minus on Niche with about 32 percent proficiency in math and reading, though it has posted Level 5 growth for four consecutive years and holds the state's "advancing" designation, which is genuine progress worth acknowledging. Families weighing Davidson County should look at their specific school zone and the magnet and private options in their budget, because Nashville's story is improving even where the district-wide numbers lag.

The tax bill is more even than people expect

Here is the part that surprises most people. Tennessee assesses homes at 25 percent of appraised value and taxes per $100 of assessed value, and the county rates are lower in Williamson than in Nashville. The Williamson County rate sits around $1.30 per $100 after the 2025 reappraisal, with Brentwood adding about $0.19 for city services, while Davidson County's rate for 2025-26 is roughly $2.78 to $2.81 per $100.

But the rate is only half the story, because you pay it on the price. On an effective-rate basis that works out to about 0.34 percent of home value in Williamson County versus about 0.57 percent in Davidson. Run the numbers against the medians: on a home near Williamson County's median value of roughly $870,000, the annual property tax bill lands around $3,000. On a home near Nashville's median of about $440,000, it is around $2,500. The Williamson bill is higher by a few hundred dollars, not the thousands people expect. The premium you pay for Franklin or Brentwood shows up in the purchase price, not in an outsized annual tax bill.

The market has already made its point

The market argument is quieter but just as real. Williamson County's median sale price was about $927,000 over the three months ending in August 2026, up about 3.1 percent from a year earlier, with homes spending roughly 40 days on the market. Franklin's median for closed single-family sales ran about $907,000 in the 90 days ending in September, with around 3.7 months of supply, still a seller-favorable number.

Now compare that with what people in the forums remember. Longtime residents point out that Franklin neighborhoods that sold in the mid-$300,000s a little over a decade ago now trade in the $600,000s, $700,000s, and beyond. That is a re-rating, not a bubble: the county has become one of the most desirable places to live in the Southeast, and demand has kept pace through rising mortgage rates. This fall the 30-year fixed rate is hovering around 7.4 percent, up from about 6.3 percent a year earlier, and Williamson prices have still climbed modestly. There is more room to negotiate than there was a few years ago, but the floor under values is firmer than in almost any market I know. For the fuller picture, see our Middle Tennessee market report.

What the premium does not buy

For honesty, here is what the premium does not buy. It does not buy a short commute to downtown Nashville: the drive from Franklin to the core of the city is long enough that it is worth timing twice, in real traffic, before you commit. It does not buy the same square footage: in many price bands, Nashville and the counties south of it deliver a larger home on more land for the same money, which is exactly why first-time buyers and young families are shopping Spring Hill and on down into Maury County. And it does not buy a low door price: single-family homes in Franklin generally start around $650,000, so the premium carries a real entry barrier.

How to decide for your family

Start with the school zone, not the county line. Two houses ten minutes apart can feed into materially different schools, and our guides to Franklin and Brentwood get into that level of detail. Then run the full carrying cost, not just the payment: property taxes at the rates above, insurance, and the commute. Finally, look at resale history in the specific neighborhood, because the premium is only worth it if the market you are buying into is one other families will want in seven years.

That last point is what matters for most homeowners. People rarely buy in Franklin and regret it at closing. They occasionally regret the commute, or the yard, or the fact that they bought sight unseen. Those are the risks worth managing, and they are exactly what a local agent who works with relocating families every week is there to manage. If you are early in your search, our relocation guide walks through the full moving process step by step, and the buying guide covers the offer side.

The bottom line

The premium is real, it is measurable, and for most families moving to Middle Tennessee with school-age children, it is worth paying. The schools are documented, the market has the stability to show for it, and the tax bill is more reasonable than the sticker price suggests. The right way to test it is with your own numbers: your school zone, your commute, your budget. I would be glad to run them with you before you make an offer on either side of the county line.
