A number went around the Golden Isles real estate world earlier this year that should have raised more eyebrows than it did: Brunswick home prices, one major listing platform reported, were up 173 percent year over year in February 2026. If you read that headline without asking a follow-up question, you'd walk away thinking the mainland's long-running discount to St. Simons and Sea Island was closing fast.
Ask the follow-up question anyway. That 173 percent figure came from eight closed sales. Eight. In a data set that small, one historic Old Town home selling for $700,000 and one starter house selling for $110,000 can swing the "median" by tens of thousands of dollars in either direction, and the resulting percentage change tells you almost nothing about where the broader market is actually headed. This is the first thing worth understanding if you're weighing Brunswick against the islands: the price gap between them is real, but the headline percentages you'll see quoted about either market deserve a second look before you build a decision around them.
Why Brunswick's median price keeps contradicting itself
Pull three sources for the same general window in early 2026 and you'll get three different pictures of Brunswick.
| Source | Period | Reported figure | What's driving it |
|---|---|---|---|
| Redfin | February 2026 | $335K median sale price, up 173.1% year over year | Based on 8 closed sales, with days on market stretching to 109 from 51 the year before |
| Movoto | March 2026 | $347,990 median sale price | Reports 500 homes sold, the same figure listed elsewhere on the page as active inventory |
| Zillow (Zillow Home Value Index, city boundary) | 2026 | $222,942, up 10.5% year over year | Index-based estimate across the full city footprint |
| Zillow (Zillow Home Value Index, ZIP 31521) | 2026 | $254,179, down 2.3% year over year | Same brand, different geography, opposite direction |
Notice that the last two rows come from the same company. One shows Brunswick prices climbing double digits. The other, pulling from a slightly different boundary, shows them falling. Neither is wrong exactly. They're measuring different things: a city limit versus a ZIP code, an index built from estimated values versus an actual transaction count that's thin enough to be noisy on its own.
This is the mechanism a buyer needs to understand before treating any single "Brunswick is up" or "Brunswick is down" claim as settled. Brunswick's home sales volume is low enough that its median price is genuinely volatile from month to month, and different data providers slice the geography differently enough that they can point in opposite directions using the same underlying market. If you're cross-shopping Brunswick against the islands, the honest starting point isn't a specific percentage. It's the fact that Brunswick's numbers move around more than the underlying housing stock does.
Why St. Simons Island's numbers are steadier, for a different reason
Compare that to St. Simons. Redfin's three-month window through May 2026 put the median sale price at $664,000, down 2.9 percent from the same period the year before, drawn from 148 homes sold in May alone. Movoto's June 2026 figures showed 457 homes sold that month, up from 403 the year before, with a median around $749,000 and days on market stretching to 81 from 53 a year earlier.
The specific numbers matter less here than the sample size behind them. St. Simons is closing well over a hundred transactions most months. That's enough volume that a single luxury waterfront sale or a cluster of starter condos doesn't swing the median the way it can in a market moving eight houses a month. When you hear that St. Simons prices softened slightly through the spring of 2026, that's a more trustworthy signal than anything Brunswick's smaller, choppier data set can currently offer, simply because of how many transactions are behind it.
If you're a buyer trying to read the market's direction rather than just its snapshot, this is the practical lesson: on the islands, trust the trend line. In Brunswick, trust the range, not the point estimate, until more sales accumulate to smooth it out.
The cost the sale price never mentions
Here's where the comparison gets more interesting than a simple discount story. Even if Brunswick's median were perfectly stable at, say, $300,000 against St. Simons at $700,000, that gap understates the real difference in what it costs to own each property year over year, because of flood insurance.
Barrier island oceanfront property, the kind that defines much of St. Simons' beachfront and Sea Island's shoreline, typically sits in FEMA's Zone VE, the flood classification reserved for locations exposed to wave action on top of rising water, not just standing floodwater. That designation is built specifically around storm surge and wave force, which is why coastal insurance data treats it as the costliest flood tier on the map. Industry data covering Georgia's coastal counties, Glynn County among them, has documented flood premiums running $1,500 to $2,800 or more annually for oceanfront and storm-surge-exposed properties, a cost that's separate from, and in addition to, standard homeowners insurance and any named-storm deductible, which in Georgia typically runs 1 to 3 percent of the dwelling's value on coastal properties.
Brunswick's housing stock, sitting on the mainland rather than directly on the open coastline, structurally doesn't carry that same wave-action exposure the way an oceanfront St. Simons parcel does. That doesn't mean Brunswick has no flood risk. Marshfront and low-lying lots exist and some require coverage. But the specific driver that pushes premiums toward the top of that range, direct wave exposure, isn't the default condition for most of Brunswick's neighborhoods the way it is for beachfront property on the islands.
Run the math over a typical hold period and the gap widens. A buyer choosing Brunswick over St. Simons isn't just saving on the purchase price. They're also very likely avoiding a recurring annual cost that, compounded over five or ten years of ownership, adds real money to the island side of the ledger that a simple sale-price comparison never shows.
What's actually changing in Brunswick, separate from the price noise
None of this means Brunswick is standing still. It's worth separating "the median price is statistically unreliable right now" from "nothing is happening in Brunswick," because plenty is.
Downtown Brunswick earned the Georgia Downtown Association's 2026 Downtown of the Year award this month, the association's top honor for downtown revitalization, recognizing planning, historic preservation, and economic development work concentrated in the historic core. That's not a marketing claim. It's a statewide peer recognition of work that's been visibly underway for several years.
Behind that award sits a string of concrete developments the Golden Isles Development Authority has been tracking through its 2025 fiscal year:
- More than $100 million in new capital investment and over 300 new jobs recorded across the authority's FY2025
- A Buc-ee's location that opened bringing roughly 200 jobs and regional traffic
- Wallenius Wilhelmsen's 300-acre vehicle processing facility opening at the Port of Brunswick in early 2025
- Hillpointe and JB2 breaking ground on a combined 560,000-plus square feet of industrial space at Exit 42
This is the piece a headline median price will never capture. Job creation, port investment, and industrial buildout are demand-side signals that tend to show up in housing markets with a lag, often well after the announcements themselves. If Brunswick's transaction volume climbs over the next year or two, and there's reason to think it will given this pipeline, its median price should also become a steadier, more meaningful number simply because there will be more sales behind it.
What this means if you're choosing between the two markets
If you're weighing a move to Brunswick against a move to St. Simons Island, the sale price you see quoted for either market deserves the same treatment: ask how many transactions are behind the number before you trust the percentage attached to it. On St. Simons, that number is usually large enough to trust directionally. In Brunswick right now, it usually isn't, which means the market could be considerably stronger or weaker than any single month's headline suggests.
Separately from that, price the actual cost of ownership, not just the purchase price, before assuming the island premium is what it looks like on paper. Flood zone designation, not city limits, is what drives the biggest swing in your annual carrying cost on the coast, and that number is available from your insurance agent before you ever make an offer.
And watch Brunswick's fundamentals rather than its monthly median. A downtown award, a port expansion, and an industrial buildout at Exit 42 tell you more about where demand is headed over the next few years than a percentage built on eight closed sales ever will.

Frequently asked questions
Is Brunswick's home price really up 173 percent? That figure reflects one data provider's February 2026 median, built on a sample of only eight sales. A change that size on that few transactions reflects which specific homes sold that month more than it reflects a market-wide shift. Larger samples from the same general period showed a far calmer picture.
Does Brunswick require flood insurance? It depends on the specific parcel's FEMA flood zone designation, not the city as a whole. Homes in high-risk zones like AE typically require it if there's a federally backed mortgage. Homes in lower-risk Zone X often don't, though optional coverage is still worth considering given Georgia's exposure to tropical storm rainfall even outside mapped flood zones.
Why do the price gap and the flood insurance gap both matter for the same decision? Because they move in the same direction. Brunswick's lower purchase price and its generally lower flood insurance exposure both point toward a lower total cost of ownership than an equivalent oceanfront purchase on the islands, even before you factor in that the islands' higher price tag comes with a deeper, more liquid resale market.
