As of March 2026, the median home sale price in the Treasure Island to Surfside Beach corridor is $367,000, with 27 months of supply and an average of 316 days on market — a clear buyer's market across Brazoria County's Gulf Coast communities.
If you own a beach house for sale in Surfside Beach Texas, or you've been watching the Treasure Island Texas market hoping to buy, March gave us a clear picture of where things stand. Eight homes closed. Two hundred sixteen are still waiting for a buyer. The data is in, and it tells a story worth reading.
Carter Signature Properties just released the full interactive March 2026 market report covering home sales, beachfront lots, showing activity, and detailed sold data across the corridor. Below is your plain-English breakdown — with a link to the full report at the end of each section.
The Big Picture: A Buyer's Market on the Texas Gulf Coast
With 216 active homes and only 8 sales in March, the Surfside Beach to Treasure Island Texas market is carrying 27 months of supply. A balanced market sits at around 6 months. That gap matters — it means buyers have options and sellers have to compete on price.
The median sale price landed at $367,000, with sellers averaging 96.5% of their list price. Buyers are negotiating, and they're winning about 3.5 cents on every dollar. If you're pricing a home for sale in Surfside Beach Texas right now, list price strategy isn't optional — it's everything.
"Correctly priced homes at entry level sold in under 120 days. Luxury properties averaged well over a year on market. The market isn't broken — it's just honest."
Home Sales: What Actually Closed in March
Eight homes changed hands in March across the coastal corridor, and they tell a wide story.
The fastest closes happened at the entry level. A two-bedroom on Texas Street in Surfside sold in 78 days at full list price — $200,000. A Gulf Ridge home went in 105 days at $230,000. Correctly priced, entry-level coastal living is still finding buyers quickly.
At the luxury end, patience was the price of admission. A six-bedroom home in Seahorse Estates on Bluewater Highway — 5,260 square feet of new construction — closed at $2,615,000 after 492 days on market. A Treasure Island Texas home sold for $699,000 after 669 days. Premium beachfront homes for sale are not impulse purchases. The right buyer exists — they just take longer to arrive.
Every closing — price per square foot, days on market, sale-to-list ratio — in one downloadable, offline-capable report.

Beachfront Lots & Coastal Land: Buyers Have Real LeverageIf you've been thinking about buying land to build a beach house on the Texas Gulf Coast, right now is worth paying attention to.

Here's the active lot inventory, consolidated by community — B T Archer, Nesmith, and every other Surfside subdivision rolled into Surfside Beach:

Showings: Buyers Are Out There — But Patient
Showing activity held steady through March across both Surfside Beach Texas to Treasure Island Texas properties. Buyers are touring. The foot traffic is real.
What's not happening is fast conversion. With an average of 316 days on market corridor-wide, showings are not turning into offers overnight. The homes getting multiple showings and real offers share one thing: they're priced where the market actually is, not where the seller hopes it might be.
According to data from the Texas A&M Real Estate Center, coastal markets with high inventory-to-sales ratios consistently reward sellers who price correctly from day one over those who start high and reduce later. Cumulative days on market compounds — and buyers notice.
