Market rows: CHS Regional MLS market statistics, residential, October 2025 to September 2026. The 12-month median is the median of the monthly medians; months of supply is average homes for sale divided by average monthly sales. Yearly figures are the median of each year's monthly median sold prices for the MLS city of Johns Island. The 2026 rows are closed residential sales with a Johns Island city name, January 1 to October 21, 2026.
Are Johns Island home prices still going up?
Slowly, if at all. The big jump came in 2021 and 2022, when the yearly median went from about $416,000 to about $562,000. Since then it has crept up: about $596,000 in 2023, $607,000 in 2024 and $645,000 in 2025. The last 12 months land in the same place, around $641,000.
Monthly numbers bounce more than they mean. Johns Island only has about 55 to 95 sales a month, and the mix swings between townhomes, new construction and big Kiawah River and waterfront homes. June 2026 hit about $695,000, and July through September ran $610,000 to $630,000. A summer-to-fall dip like that is normal here, so I'd wait for a few more months before calling it a trend. See how it compares with other areas on my price history page.
Is it a buyer's market or a seller's market?
In between, and leaning toward buyers compared with 2021 and 2022. Over the last year Johns Island averaged about 245 homes for sale against about 70 sales a month. That's roughly three and a half months of supply. Many agents treat about six months as balanced, so sellers still have the edge on a well-priced home, but buyers have choices.
The negotiating room is real. The median home sold for about 96.6% of its original asking price, and the median monthly days on market ran about 50. Homes priced right still sell fast: counting each 2026 sale on its own, the median was about 34 days on market. The ones that sit are usually the ones that started too high.
What's actually selling?
Newer and bigger homes. The median 2026 sale was built in 2019 and had about 2,311 square feet, and 29% of everything that sold was built in 2024 or later. About 19% were townhomes. About a quarter sold under $500,000 and about a fifth sold for $1 million or more, mostly Kiawah River and waterfront homes.
That much new construction matters for resale sellers. You're competing with builders who can offer rate buydowns and closing cost help. If you're selling a 10-year-old home in a neighborhood where a builder is still selling, price against the builder's net price after incentives, not just the last resale.
How much more is being built?
A lot, but at a steady pace rather than a surge. In the City of Charleston's part of the island, new construction permits ran 138 in 2024 and 117 in 2025, and 109 through October 14, 2026, against 103 by the same date in 2025. City records show about 2,970 homes approved across 33 developments, with about 1,400 still to be built. Those counts don't include unincorporated county land, where Kiawah River is entitled for up to 1,285 homes and had about 400 by August 2026.
There's also a ceiling on sprawl. The Lowcountry Land Trust says about 80% of Johns Island sits outside the Urban Growth Boundary and about 8% is under conservation easement. Follow every project with sources on my Johns Island growth tracker.
What changes in 2027 and 2028?
Mostly roads. The Maybank Highway fourth lane, from River Road to the Stono River bridge, was in final design in September 2026, with construction expected to start in early 2027. Published start dates have conflicted, so check with the county. On Main Road, the Segment A project with the new flyover at US 17 is under construction, with a contract completion date of September 27, 2028.
The I-526 extension across the island was cancelled in 2025, and the county moved that money to other road projects. Charleston County's transportation sales tax is on the November 3, 2026 ballot; its project list includes a $65 million southern Pitchfork road off Maybank and a $5 million roundabout at Main Road and Mary Ann Point Road. On the public side, Fire Station 23 on Maybank is under construction and the Johns Island Recreation and Aquatic Facility has been approved.
Where I land
I live on Johns Island, and I don't predict prices. What I'm watching instead is supply. If homes for sale climb past about 300 while sales stay flat, buyers will get more leverage. If the Maybank fourth lane actually starts on time, I'd expect it to help the neighborhoods closest to the Stono bridge first.
For buyers, homes that have sat for 60 days or more are where the negotiating room is. For sellers, price against the last 90 days of sales in your own pocket of the island, not the 2022 headlines. A well-priced home here still sells in about a month.
Common questions
Are home prices dropping on Johns Island?
Not year over year. The yearly median rose from about $607,000 in 2024 to about $645,000 in 2025, and the last 12 months ran about the same. Monthly medians dipped in late summer 2026, which is common here and too short to call a trend.
How many homes are for sale on Johns Island?
About 227 at the latest monthly count (September 2026), and about 245 on average over the last year. With about 70 sales a month, that's roughly three and a half months of supply.
Is the I-526 extension to Johns Island still happening?
No. The state ended the funding agreement in May 2025 and the extension was cancelled. Charleston County moved the money it had set aside to other road projects, including the Maybank Highway fourth lane.
When will Maybank Highway be widened?
The fourth lane from River Road to the Stono River bridge was in final design in September 2026, with construction expected to start in early 2027. Published dates have changed before, so check the county's project page.
