Moving to Columbia & Maury County, TN (2026): Spring Hill's Southern Spillover, the GM Effect & Home Prices

Columbia, the seat of Maury County, is the affordable southern continuation of the Spring Hill–Franklin job corridor: its median sale price was about $392,000 in March 2026 (Redfin), versus roughly $975K–$993K county-wide in Williamson County in mid-2026 (Redfin / Orchard) — so a buyer priced out of Franklin can often find more house, or a newer home, by moving a few exits south on US-31 / I-65. It sits about 11 miles (roughly 17–18 minutes) south of the General Motors / Ultium battery complex in Spring Hill and about 30 miles (roughly 38 minutes) from Franklin, anchored by a genuine historic courthouse square and one of the busiest new-construction markets in the region.

So is Columbia a good place to live? For many Middle Tennessee buyers it answers a hard question — how do you stay near the Spring Hill and Cool Springs employment centers without paying Williamson County prices? Below, our team lays out the real numbers, commute distances, the downtown, and the new-construction landscape so you can decide for yourself. We deal in dated, sourced figures, not predictions.

Population & growth: among the fastest-growing counties in Tennessee

Maury County's growth shows up in the data, not just the marketing. The county posted about 3.2% population growth in the year ending mid-2025 — one of the strongest rates in the state and an acceleration over the prior year — according to U.S. Census Bureau estimates released in March 2026 and summarized by the Tennessee State Data Center. (By total numeric gain, Davidson County led the state in 2025; Maury ranks among the leaders by growth rate.) Columbia, the county seat, had an estimated 2026 population around 52,000 and has grown roughly 24% since the 2020 Census count of 41,994 (World Population Review, 2026). County-wide, Maury sits near 118,000–119,000 residents (World Population Review, 2026).

The why is straightforward: affordability relative to Williamson County, Tennessee's lack of a state income tax, and a wave of economic investment (the Maury Alliance documents multiple major projects and substantial capital investment over the past decade). For buyers, the practical takeaway is that you're moving into a growth market — inventory, builders, and amenities are expanding, but so is competition for well-located homes.

Home prices: well below Williamson, with room to choose

Here are dated, sourced numbers rather than predictions. As always, the figures move month to month, so treat these as a snapshot, not a forecast — and ask our team for the latest pull before you make decisions.

• •Columbia median sale price: about $392,000 in March 2026, down roughly 2% year-over-year (Redfin). Other trackers showed monthly medians in the $410K–$450K range in spring 2026 (Orchard, Movoto), reflecting differences in how each measures the mix of homes sold.
• •Columbia price per square foot: about $202 in March 2026 (Redfin).
• •Williamson County, for comparison: a median around $975K–$993K county-wide in mid-2026 (Redfin / Orchard) — roughly two and a half times Columbia's median.
• •The result: a buyer priced out of Franklin or central Spring Hill can often find substantially more house, or a newer home, by moving a few exits south.

On mortgage rates and the broader outlook, we don't make predictions in our own voice — we point to the published forecasters and let you budget against their ranges. As of late June 2026, Freddie Mac's Primary Mortgage Market Survey put the average 30-year fixed rate at about 6.49% (Freddie Mac, June 25, 2026). For year-end 2026, major forecasters generally project rates drifting modestly lower into roughly the high-5% to low-6% range — Freddie Mac near 5.8%, the Mortgage Bankers Association (MBA) near 5.9%–6.1%, and Fannie Mae near 6.0%–6.3% in its May 2026 forecast — while the National Association of Realtors (NAR) sees rates easing further into 2027. Every one of them cautions that these are estimates and the future can't be guaranteed, so use the published ranges rather than any single number when you plan.

The GM Spring Hill effect: an employment anchor on the county line

The largest economic gravity well in the area is the General Motors Spring Hill complex and the adjacent Ultium Cells battery plant — the GM–LG Energy Solution joint venture — on the northern edge of Maury County. Ultium represented a roughly $2.3 billion investment announced earlier this decade (Maury Alliance; GM). In July 2025, GM and LG announced plans to upgrade the Spring Hill facility to produce lower-cost lithium-iron-phosphate (LFP) cells, and in March 2026 the joint venture said it would begin making LFP cells for the stationary energy-storage market at Spring Hill in the second quarter of 2026, backed by a roughly $70 million retooling investment (CNBC, July 2025; Ultium Cells / Electrek, March 2026).

We mention this as neutral context, not a guarantee of any particular hiring level: large manufacturers adjust headcount with product cycles, and reporting in 2025–2026 reflected both temporary layoffs and recalls of workers as the Spring Hill operation re-tooled — the energy-storage changeover was reported to bring back roughly 700 employees who had been laid off in January 2026 (Ultium Cells; Yahoo Finance, 2026). What's durable for housing demand is the corridor itself — GM's assembly plant, the battery operation, and the broader supplier base have turned the Spring Hill–Columbia line into a daily-commute job center, which is part of why homes just south in Maury County stay in demand.

Commute: the southern spillover, mapped

Columbia's appeal is geographic. It is the next stop south after Spring Hill on US-31 / I-65, which keeps the major commutes manageable for a town this affordable.

• •Columbia to the GM/Ultium Spring Hill plant: about 11 miles, roughly 17–18 minutes by car via US-31 (distance-cities.com).
• •Columbia to Franklin (Williamson County job centers, including Cool Springs): about 30 miles, roughly 38 minutes by car (travelmath / distance-cities.com).
• •Columbia to downtown Nashville: roughly 45 miles, primarily via I-65 (multiple mapping sources).
• •Spring Hill itself sits between Columbia and Franklin, so many Maury County residents commute only as far as Spring Hill for work, shopping, and dining.

The honest caveat: US-31 and I-65 through Spring Hill see real rush-hour congestion as the corridor has grown. Our team always recommends test-driving your specific commute at the actual hour you'd travel, from the specific subdivision you're considering, before you commit.

Historic downtown Columbia: the town center that anchors it

One thing Columbia has that newer suburbs don't is a genuine historic core. The Columbia Commercial Historic District centers on the courthouse square, ringed by shops, restaurants, boutiques, and antique stores (Visit Columbia TN). A few specifics worth knowing:

• •Mule Day — what began as 'Breeder's Day' in 1840 is now an annual April celebration that draws crowds well into the six figures (organizers and coverage cite 200,000-plus visitors) over several days (Visit Columbia TN; City of Columbia).
• •The James K. Polk Home — built in 1816 and the only surviving private residence of the 11th U.S. President, it sits a few blocks from the square (James K. Polk Museum).
• •The Arts District — anchored by the Columbia Arts Building (CAB), the district formed around restored warehouses and has drawn artists, makers, and new local businesses (Visit Columbia TN).
• •Main Street program — Columbia has long participated in Tennessee's Main Street downtown-revitalization program (TNECD), which has guided steady reinvestment in the square.

For buyers, that means Columbia offers a walkable, event-driven downtown lifestyle that a new-construction-only suburb can't match — alongside the newer neighborhoods on the city's edges.

New construction in Columbia & Maury County

Maury County is one of the most active new-construction markets in Middle Tennessee, with roughly 90 communities listed across Columbia, Spring Hill, and Mount Pleasant (NewHomeSource, 2026). That new-build inventory is a big reason buyers can find newer homes here at prices well under Williamson County. Active and recent communities our team tracks include builders such as Drees Homes (Bear Creek Overlook in Columbia, with floor plans recently starting around $300K), Celebration Homes (at Harvest Point, just north in Spring Hill), Centex, and other regional and local builders; Mount Pleasant has also approved subdivisions adding hundreds of additional homes (NewHomeSource; local reporting).

A quick, positive word on representation when you buy new construction. The friendly agent in the model-home center works for the builder — and the builder is well represented in that transaction. Having an independent agent on your side, at little or no cost to you in most cases, means someone is reviewing the builder's contract, tracking incentives and lender credits, scheduling and attending independent inspections (including pre-drywall), and negotiating on your behalf at warranty time. Our team partners professionally with builders and listing agents across Maury County; representing you well and keeping those relationships strong are not in conflict.

Property taxes & cost of living

Tennessee has no state income tax (the Hall tax on dividends and interest was fully repealed in 2021), which is a meaningful draw for relocating households. Maury County's property-tax burden is modest by national standards — third-party trackers put the county's median effective rate around 0.48%, versus a U.S. median near 1.02% (tax-rates.org; SmartAsset). City-of-Spring-Hill and city-of-Columbia residents add a municipal rate on top of the county rate, so your total bill depends on whether your address is inside city limits and which school and special districts apply. For an exact figure, our team can pull the current rate for any specific address — or you can call the Maury County Assessor directly.

Who tends to look at Columbia & Maury County

Rather than tell anyone where they 'should' live, here's the practical math we see buyers run. People weighing Columbia are usually comparing it against Spring Hill and Franklin and trading a longer commute for a lower price and more home. If your work is in or near Spring Hill, the math is especially favorable. If you want a historic, walkable town center with festivals and an arts scene, Columbia's square is a real differentiator. If your priority is the shortest possible Nashville commute, you'll want to honestly weigh the roughly 45-mile drive. We'll lay out the comparison with current numbers and let you decide.

Frequently asked questions

Is Columbia, TN cheaper than Spring Hill and Franklin?

Generally yes. Columbia's median sale price was about $392,000 in March 2026 (Redfin), while Williamson County — which includes Franklin and the northern half of Spring Hill — carried a county-wide median around $975K–$993K in mid-2026 (Redfin / Orchard). You typically get more home, or a newer home, for the money in Columbia, in exchange for a longer commute to the Williamson County job centers.

How far is Columbia from the GM Spring Hill plant?

About 11 miles, roughly a 17–18 minute drive via US-31 (distance-cities.com). That short hop to the GM assembly and Ultium battery complex is a major reason Columbia functions as the affordable spillover for the Spring Hill job corridor.
