The analysis draws from 56 closed residential transactions in Old Marsh Golf Club, sourced from BeachesMLS via Spark API, spanning January 2020 through March 2026. For each sale, we track closing price, price per square foot, days on market, list-to-sold ratio, financing method, home size, lot acreage, build year, and property type. All 56 transactions are single-family estates in a community of approximately 60 homes.
Inventory and How Often Homes Trade
Old Marsh has approximately 60 homes. All are single-family estates. There is zero condo or villa product. In a corridor where Admirals Cove has 900+ residences, Old Palm has 300, and Frenchman's Creek has 400+, Old Marsh is a fundamentally different scale of community. The only comparable lot count in the region is Bears Club at 46 estates, and Bears Club operates at a different price tier ($1,484/SF versus Old Marsh's $1,037/SF in 2024 to 2025).
Over the six-year period from 2020 through early 2026, 56 sales closed for a combined volume of $210.7 million. That is roughly 9 sales per year. In a community of 60 homes, 9 annual transactions represent a 15% turnover rate, meaning nearly every home has changed hands over the dataset period. This is not churn or distress: the appreciation of +163% (the second-highest in the corridor) and the 95.2% list-to-sold ratio confirm a healthy, liquid market. Based on practitioner observation, much of the turnover reflects a generational transition: original or long-term owners selling to a newer cohort of buyers drawn to the Pete Dye course and the Audubon setting.
Like other private equity clubs in the corridor, Old Marsh requires a membership purchase on top of the home price. The current initiation fee is not published in MLS data and varies by membership category; prospective buyers should confirm the current amount, refund schedule, and transfer terms directly with the club or through their agent. At Old Palm, the comparable equity membership is $350,000. The Old Marsh fee should be factored into the total entry cost alongside the purchase price, closing costs, and any planned renovation budget.
The year-by-year pattern shows a community that absorbed pandemic demand early and has sustained pricing above $800/SF since 2022. In 2020, 12 sales closed at $395/SF. In 2021, another 12 sales at $498/SF. By 2022, pricing crossed $794/SF on 9 sales. Since then, the market has stabilized above $800/SF with volume fluctuating between 4 and 10 sales per year depending on available inventory. The 2025 market was notably active: 10 sales at $987/SF and $4.68M median, with 100% of transactions closing in cash. Early 2026 has produced one sale at $6.55M ($1,148/SF), continuing the upward trajectory.

Price Range and What Each Tier Gets You
Old Marsh's price range runs from $930,000 to $11.25M across the dataset. The core market is $1M to $5M, which accounts for 79% of all transactions (43% at $1M to $3M, 36% at $3M to $5M). Above $5M, 10 sales (18%) have closed in the $5M to $10M range, and one sale has crossed $10M (the $11.25M transaction in June 2023 at $1,222/SF). In the current market (2025), the median has moved to $4.68M; early 2026's single closing at $6.55M suggests the center of gravity is shifting upward.
Pre-2000 construction on standard lots, typically 4,800 to 6,300 SF. These homes are often original or lightly updated estates from the 1990s. At the entry tier, Old Marsh offers the Pete Dye course, Audubon setting, and 0.51-acre median lots at a price point below Old Palm's current median. The trade-off: the housing stock is older and renovation scope may be substantial.
Where the current market centers. This tier includes both renovated pre-2000 homes and 2000s-era construction in the 6,000 to 7,500 SF range. In 2025, the median closing price was $4.68M, placing the majority of current activity squarely in this bracket. Buyers at this level are typically comparing Old Marsh to Old Palm ($5.15M median) and Loxahatchee ($872/SF).
The largest estates on the most private lots, often 8,000+ SF with significant course or preserve views. The $11.25M ceiling (a 12,225 SF, 2002-built estate at $1,222/SF) confirms the community can attract ultra-luxury capital, but only one sale has crossed $10M. The practical ceiling for most transactions is $7M to $9M.
What a Typical Old Marsh Sale Looks Like
In the current market, Old Marsh trades at $1,037/SF (2024 to 2025 combined on 14 sales), with a 2025 median closing price of $4.68M across 10 transactions. Early 2026's single sale at $6.55M ($1,148/SF) suggests continued upward pressure, though the sample is too small for a reliable read. The community's physical profile: 6,291 SF median home on 0.51 acres with four bedrooms. The lots are among the largest in the PBG corridor, comparable to Old Palm (0.46 acres) and substantially larger than Frenchman's Creek (0.22 acres) or Mirasol (0.20 acres).
The housing stock skews older than Old Palm. Five of the 56 sales involved pre-1990 construction, 17 involved 1990s builds, and 19 involved 2000s builds. That is 41 pre-2010 homes, or 73% of all transactions. The remaining 27% is split between 10 sales of 2010-2019 product and 5 sales of 2020 or later construction. The pricing gap between eras is substantial: the 2010-2019 cohort carries an all-time cohort median of $987/SF versus $580/SF for the 1990s cohort and $588/SF for the 2000s cohort. The 2020+ cohort (5 sales) trades at $1,092/SF. As with all corridor clubs, these cohort figures blend six years of pricing history and should not be read as current pricing benchmarks; a 1995-built home selling in 2025 trades at current-market rates adjusted for condition, not at $580/SF. But the structural premium for newer construction is clear.
Days on Market and the Negotiating Dynamic
Old Marsh's historical median DOM of 34 days is the fastest in the entire corridor, ahead of Admirals Cove (44 days), Loxahatchee (56 days), Old Palm (76 days), Lost Tree (92 days), and Bears Club (103 days). In a 60-home community, this speed reflects the fundamental supply constraint: when a home lists, the buyer pool for Pete Dye Audubon-certified product in this size range knows immediately, and those who have been waiting move quickly.
The current market is still fast, but not 2021-fast. In 2025, median DOM was 62 days. In 2024, it was 56 days on only 4 sales. In 2023, it was 16 days (the lowest single-year figure in the dataset). The variability reflects the small sample: one slow-moving estate at $7M with 194 days on market can move the 2025 median from 35 days to 62 days. The practical read: well-priced Old Marsh homes continue to transact within one to two months during season. Homes priced above the market or listed outside the October-to-April window will wait longer.
The list-to-sold ratio of 95.2% (all-time) indicates tight pricing. In 2024, the ratio was 97.4%. In 2025, it was 94.8%. Buyers are paying within 5% to 6% of asking price, and sellers who price accurately are not leaving much on the table. The 2022 and 2024 figures (both 97.4%) suggest that in years with limited inventory, sellers have more leverage. At 95% cash in 2025 (and 82% across the full dataset), the buyer pool is overwhelmingly liquid, which compresses negotiation timelines and favors clean, fast offers.
With only 9 sales per year and a 15% annual turnover rate, Old Marsh inventory is structurally scarce. Not all listings surface on the MLS. In a community this small, many transactions begin as conversations between agents with existing relationships inside the club. For a buyer who is waiting for the right home, off-market access is not a convenience; it is a material advantage. Representation with an agent who has active relationships within Old Marsh meaningfully expands the pool of available properties.
HOA: Why $630 per Month Is the Lowest in the Corridor
The Old Marsh HOA runs approximately $630 per month, or $7,560 per year. This is among the lowest single-family HOAs in the corridor. Old Palm is $2,092/month ($25,104/year). Frenchman's Creek is $2,347/month ($28,164/year). Even Mirasol is substantially higher. The low HOA at Old Marsh reflects the community's design: fewer shared amenities, no marina, no beach club, no extensive resort-style programming. The club provides a championship course, a clubhouse with dining, and common-area maintenance on 456 acres. What it does not provide, you do not pay for.
For the buyer comparing total carrying cost across communities, the $7,560 HOA is a meaningful differentiator. But it is only one line item. Annual club dues and food and beverage minimums (billed separately by the club), property taxes (approximately 0.75% effective rate, or roughly $36,000/year at the 2024 recent median of $4.83M), and property insurance ($20,000 to $50,000+ depending on build year, roof age, and mitigation features) are all additional. The realistic total annual carrying cost at current market pricing is $80,000 to $120,000 before any mortgage service, significantly less than Old Palm or Frenchman's Creek at comparable home values.
Old Marsh's low HOA is a feature, not a limitation. The buyer drawn to Old Marsh is not looking for a full-service club with a marina, a beach club, and three restaurants. They are looking for a great course in a natural setting with the lowest possible overhead. The $7,560/year HOA buys gated security, road and common-area maintenance across 456 acres, and access to the Pete Dye course and clubhouse. At Frenchman's Creek, the $28,164/year HOA buys two courses, a marina, and a private beach club. Both models work; they serve different buyers. If you want the amenities, you pay for them. If you want the course and the land, Old Marsh delivers both at a fraction of the carrying cost.
456 Audubon-Certified Acres
Old Marsh's Audubon certification is not a marketing label. It is a formal environmental designation that governs how the land is managed: pesticide use, water management, wildlife habitat, and buffer zones are all subject to Audubon standards. The 456-acre footprint is surrounded by natural preserve land, creating a visual and ecological environment that is fundamentally different from the manicured-landscape feel of communities like Mirasol or BallenIsles.
For the right buyer, this is the defining feature of Old Marsh. The course plays through preserved wetlands and native vegetation. Wildlife is present and visible: wading birds, raptors, and reptiles are part of daily life here in a way that is not typical of a gated golf community. The trade-off is that the Audubon management approach means the course and common areas do not have the wall-to-wall manicured look that some golfers prefer. The fairways are maintained to championship standards, but the roughs and transition areas are managed for ecological health, not visual uniformity. For the buyer who values the natural setting, this is precisely the point.
The Audubon designation has a practical implication for property owners. Landscaping on individual lots in an Audubon-certified community may be subject to guidelines that restrict certain plant species, irrigation practices, or hardscape additions near preserve buffers. These are not onerous restrictions for most estate owners, but they are worth understanding before closing. A buyer planning a major outdoor renovation should confirm the scope of Audubon-related covenants with the HOA before finalizing design plans.
Bottom Line
Old Marsh is the corridor's scarcity play. Sixty homes on 456 Audubon-certified acres with a Pete Dye course is a combination that does not exist elsewhere in South Florida. The data confirms the proposition: +163% appreciation (second in the corridor), historically the fastest DOM in the region, and 100% cash in 2025. The low HOA ($7,560/year) reflects a community that delivers golf and nature without the overhead of full-service programming. Current pricing above $1,000/SF places Old Marsh nearly on par with Old Palm ($1,101/SF) despite having one-fifth the lot count, which suggests the scarcity premium has not fully materialized in the $/SF. For a buyer who wants a boutique club experience in a natural setting, the data case for Old Marsh is strong and the supply window is narrow.
For buyers at $3M to $5M: This is where the current market centers. Expect 6,000 to 7,000 SF estates on half-acre lots, with build years ranging from the 1990s to 2000s. At 95% L/S, offers within 5% of asking are the norm. The 62-day 2025 DOM gives you roughly one season to evaluate, but well-priced homes move faster. Pre-season is the time to position; waiting until January narrows the field.
For buyers at $5M+: Inventory at this level is thin (10 sales across six years above $5M). You are likely competing for renovated or newer product in the 7,000 to 12,000 SF range. Off-market access is a material advantage at this tier; representation with club relationships should be part of your strategy from day one.
The scarcity arithmetic: Old Marsh at $1,037/SF versus Old Palm at $1,101/SF is nearly identical pricing for a community with 60 homes versus 300. If scarcity premiums in this corridor follow the pattern of other luxury markets, Old Marsh's $/SF has room to move. The 15% annual turnover rate means you will have opportunities, but each one represents a meaningful share of total inventory. When the right home lists, the decision window is weeks, not months.
This analysis is based on 56 closed residential transactions in Old Marsh Golf Club from January 2020 through March 2026, sourced from BeachesMLS via Spark API. All 56 transactions are single-family estates. Metrics tracked per transaction include closing price, price per square foot, days on market (from list date to contract date), list-to-sold ratio (closing price divided by final list price), financing method (cash or financed), living area square footage, lot acreage, bedroom count, and year built.
Median values are used throughout as the primary central tendency measure. In a community with 4 to 12 sales per year, single outlier transactions can move yearly medians significantly. The 2024 median of $5.01M on 4 sales and the 2026 YTD figure of $6.55M on 1 sale should be interpreted with appropriate caution regarding sample size.
Build era cohort $/SF figures are all-time medians across all sale years in the dataset. They quantify the structural premium for newer construction but should not be used as current pricing benchmarks.
References to HOA amounts ($630/month), Audubon certification, and community descriptions reflect publicly available information and practitioner knowledge as of early 2026. Prospective buyers should confirm current dues, covenants, and membership terms directly with the club.
