The analysis is based on 21,852 closed residential sales at $1M and above in Palm Beach County from 2020 through 2025, sourced from BeachesMLS via Spark API. For each sale, we track closing month, days on market, and list-to-sold ratio, then segment by quarter and price tier. The result is a seasonal map that shows not just when sales close, but how the deal metrics — speed, pricing, and competition — shift across the calendar year at each level of the market. Year-specific figures cited in subsequent sections (e.g., 460 $5M+ closings) reflect 2025 data unless otherwise noted.
The Seasonal Gap at $5M and Above, 2025
When They Transact, by Tier
A luxury real estate transaction in PBC follows a lifecycle: preparation (renovations, staging, photography, pricing), pre-marketing (off-market previews, broker network outreach), active listing (MLS, public marketing), negotiation, and close. The closed sale data in the MLS captures only the final stage. But the data on when closings concentrate, combined with median DOM, lets us work backward to map the full cycle.
In 2025, the quarterly distribution of closed sales at $1M+ was Q1 28%, Q2 32%, Q3 24%, Q4 16% — a mild seasonal skew, with Q2 modestly above the other three quarters. At $5M+, Q2 absorbs 39% and Q3 drops to 18%. At $10M+, Q1 and Q2 combined account for 75%. At $20M+, Q3 accounts for 11% of annual activity — 4 sales in all of 2025. Note: the divergence charts in Section 4 track the $1M–$2M entry segment specifically, not the full $1M+ population; a small difference in Q2 share between those two figures (31% vs. 32%) reflects this narrower cut.
The higher the price tier, the more concentrated the activity in the first half of the year. This concentration has a direct implication for timing: the preparation and pre-marketing stages need to begin months before the closing window opens.
The Seller's Calendar
At $5M and above, Q2 (April through June) is the optimal closing window on every measurable dimension: highest volume (180 closings in 2025), shortest time on market (62 days), and best list-to-sold ratio (94.1%). Working backward from a Q2 close, the data maps a five-stage timeline.
Stage 1: Prepare (July–September, prior year).
Renovations, repairs, landscaping. At $5M+, preparation is not a weekend project. Kitchens, bathrooms, pool resurfacing, and exterior paint on a 5,000+ SF home take 8–16 weeks with Palm Beach County permitting and contractor schedules. The target is to be photography-ready by October.
Stage 2: Pre-market (October–November).
Professional photography, video, floor plans. Pricing analysis using closed comps and current competition. Off-market previews to the broker network. The data supports this: 44% of Q1 closings at $5M+ originated from listings that went active in October, November, or December. The pre-market stage generates early interest from agents whose seasonal clients are planning January trips.
Stage 3: Active listing (November–January).
MLS entry, public marketing, open broker events. 38% of all Q2 closings at $5M+ listed in January, February, or March; another 24% listed the prior November or December. A November listing has visibility before competition intensifies in January. A January listing hits the market as the seasonal buyer pool arrives.
Stage 4: Showings and negotiation (January–March).
The seasonal buyer pool peaks in February and March. At $5M+, the median Q2 closing spent 62 days on market. A property that listed in January and is correctly priced should be under contract by March.
Stage 5: Close (April–June).
The Q2 window. 180 of the 460 $5M+ closings in 2025 (39%) fell in this quarter. The cost of missing it, by tier, is quantified below.
The cost of missing the window, by tier (2025).
$5M+ (460 closings):
Q1 close: 70-day DOM. 91.8% of asking.
Q2 close: 62-day DOM. 94.1% of asking.
Q3 close: 102-day DOM. 92.4% of asking.
Q4 close: 147-day DOM. 92.8% of asking.
The Q2-to-Q4 gap: 1.3 points. On a $7 million list price: approximately $91,000.
$10M+ (139 closings):
Q2 close: 119-day DOM. 91.3% of asking.
Q4 close: 169-day DOM. 89.2% of asking.
The Q2-to-Q4 gap: 2.1 points. On a $15 million list price: approximately $315,000.
$20M+ (35 closings; as few as 4 in a single quarter — treat as directional):
Q2 close: 92-day DOM. 89.5% of asking.
Q4 close: 174-day DOM. 83.0% of asking.
The Q2-to-Q4 gap: 6.5 points. On a $20 million list price: approximately $1.3 million.

The Buyer's Calendar
The seasonal data surface a Q3 buyer advantage: fewer competing buyers, longer DOM, motivated sellers. At $5M+, Q3 produced 84 closings versus Q2's 180. Zero $5M+ properties sold above asking in Q3 2025. Sellers who listed in January and have not closed by July have been on market for six months, and their expectations have adjusted. The negotiating leverage is real.
The more important question is whether the properties available in summer are representative of the best inventory that came to market that year. In practice, the Q3 inventory is a filtered set. The best properties at the best locations typically sell in Q1 and Q2, when the full seasonal buyer pool is active and competing. What remains in summer is disproportionately overpriced listings, niche properties, and homes the market evaluated during season and declined to absorb. A buyer who purchases in Q3 at a larger discount from asking may still be paying market price for a property that is worth less than what sold in April. The leverage matters only for buyers who have done the evaluation work before making an offer.
The data suggests that the highest-value approach for a $5M+ buyer is not to wait for summer leftovers. It is to have access to inventory before the open market sees it.
Pre-market access (October–December): The seller's timeline shows that preparation begins in July–September and pre-marketing begins in October. A buyer with broker relationships in the PBC luxury network can preview properties during this stage, before MLS entry, before public marketing, and before the January wave of competing seasonal buyers arrives.
Q1 engagement (January–March): The freshest, best-priced inventory hits the market in Q1 when sellers are most optimistic and the product is at its best — newly staged, newly photographed, zero days on market. The buyer who is active in Q1 sees every property at its most competitive presentation. The Q2 close follows naturally.
The Q3 option: Still valid for the opportunistic buyer who is flexible on location and property type, and particularly for the prepared buyer who can move quickly on price with a clean offer. A property that has been on market for 100+ days in August, with a seller who knows the seasonal window has closed, is receptive to a well-structured offer at a number below asking. Price plus a clear path to close carries weight when the alternative is three more months of carrying costs and another round of price reductions. At $20M+, Q3 produced 4 closings in all of 2025. The inventory is thin, but the leverage is real for a buyer who has done the work before the offer.
At $10M+, the Q3 list-to-sold ratio was 93.9% — notably the highest of any quarter. This reflects selection bias: the 19 properties that closed in Q3 at $10M+ were the ones correctly priced from the start and simply needed time to find the right match. The overpriced listings from Q1 and Q2 are still accumulating DOM, and they appear in Q4 at 89.2% L/S. The Q3 "discount" is not available on the best properties. It is available on the ones that missed.
How the Tiers Diverged, 2020–2025
The seasonal calendar looked roughly similar across tiers in 2020, partly because the pandemic scrambled the normal pattern. Since then, the tiers have diverged. The charts below track Q2 and Q3 shares for two segments: the entry market ($1M–$2M, gray) and the luxury market ($5M+, black). The lines started together in 2020. They have since separated.
In Q2, the $5M+ line separated from the $1M–$2M line in 2021 and has stayed above it. In 2025, 39% of $5M+ closings occur in Q2 versus 31% at $1M–$2M. In Q3, the $5M+ share declined from 32% (2020) to 18% (2025) while $1M–$2M held near 25–26%.
The mechanism: the $5M+ buyer pool is disproportionately seasonal. They arrive in January, view in February, make offers in March, and close in April through June. By July, they are elsewhere. The $1M–$2M buyer pool is increasingly local and year-round, not tied to the seasonal calendar. As the local buyer base has grown (driven by Florida's income growth and new construction absorption), the entry tier has flattened. As the $5M+ market has attracted more seasonal wealth, its seasonal amplitude has steepened.
Bottom Line
When should a seller list? At $5M+, Q2 is the optimal outcome on every measurable dimension: 94.1% of asking, 62-day median DOM, 39% of annual volume. The preparation timeline works backward from there. Begin renovation and staging July through September of the prior year. Enter pre-market channels in October and November. Go active on MLS by January. A property that misses this window faces compounding penalties: by Q4, median DOM at $5M+ reaches 147 days and L/S drops to 92.8%. At $20M+, Q4 closings land at 83% of asking versus 89.5% in Q2 — a gap of approximately $1.3 million on a $20 million list price, though the small quarterly samples at this tier (as few as 4 transactions) mean these figures are directional.
When should a buyer engage? Q3 offers the thinnest competition (84 closings versus 180 at $5M+, zero above-asking sales) and real negotiating leverage. But Q3 inventory is filtered. The best-located, correctly priced properties typically clear in Q1 and Q2. What remains in summer skews toward listings the market evaluated during season and declined to absorb. The higher-value strategy is pre-market access in Q4 of the prior year and active Q1 engagement, when inventory is fresh. For the disciplined buyer willing to operate in summer, the opportunity is specific: a clean, well-priced offer presented to a seller past 100 days on market who understands the seasonal window has closed.
At $1M to $2M, the seasonal calendar that governs the $5M+ market does not apply in any material way. Quarterly volume is broadly uniform in 2025, driven by a year-round local buyer base that has grown substantially since 2020.
For sellers at $5M+: Prepare July through September. Pre-market October and November. List by January. Target a Q2 close.
For buyers at $5M+: Pre-market access in Q4 and active Q1 engagement delivers first look at unfiltered inventory. Summer offers succeed when they are clean, priced to close, and targeted at sellers past 100 days on market.
At $1M–$2M: Timing is secondary. The year-round market at this tier is broadly uniform.
Real estate data covers all closed residential sales (single-family and condominium) at $1,000,000 and above in Palm Beach County, sourced from BeachesMLS via Spark API. Monthly data uses the Sold Date field. The analysis covers 2020 through 2025.
Price tiers: "$5M+" = $5,000,000 and above (includes $10M+ and $20M+). "$10M+" = $10,000,000 and above (includes $20M+). "$20M+" = $20,000,000 and above. "$1M–$2M" = $1,000,000 to $1,999,999. Note: body text references to "$1M+" quarterly shares describe the full $1M+ population; the divergence charts in Section 4 track the narrower $1M–$2M segment, which explains a small difference in quoted Q2 share between the two (31% vs. 32%).
List-to-sold ratio is sold price divided by list price at time of sale — the final asking price, not the original list price. A property that undergoes one or more price reductions before selling may show a high L/S ratio relative to its final ask despite meaningful seller concession from the original list. The metric is reliable in aggregate across hundreds of transactions but should not be over-indexed at the individual deal level. DOM is listing date to sold date.
Listing-month-to-closing-quarter analysis: the figures cited in Stage 2 and Stage 3 of the Seller's Calendar (44% of Q1 closings originated from listings active in October–December; 38% of Q2 closings listed in January–March; 24% listed in the prior November–December) are derived from the same BeachesMLS dataset by cross-referencing the listing date and closing date for each transaction at $5M+ in 2025.
The dollar-value estimates of the L/S gap (e.g., "approximately $91,000 on a $7M list price") apply the gap between the highest and lowest quarterly L/S medians to a representative list price for the tier. These estimates represent the gap applied to list price and are illustrative rather than precise for any individual transaction.
The $20M+ tier has small sample sizes (35 sales in 2025, as few as 4 in a single quarter). Quarterly metrics at this tier should be read as directional. The $10M+ tier (139 sales in 2025) is more statistically reliable but still subject to composition effects in any given quarter.
The Q3 L/S result at $10M+ (93.9%, the highest of any quarter) reflects selection bias: the properties that close in Q3 are those that were correctly priced and attracted a buyer despite reduced seasonal demand. Overpriced Q1 and Q2 listings that did not close during season remain on market and appear in later quarters' DOM and L/S figures.
