Coastal Miami condo inventory hit a 3-year low in April 2026, falling 13% to 3,919 listings, according to The Real Deal. Condo closings rose 15% to 693, the first annual increase since Q4 2024. Supply is contracting in Sunny Isles, Bal Harbour, Key Biscayne, and Fisher Island. Buyers who wait for conditions to ease will find fewer choices at higher prices.
On April 17, 2026, The Real Deal reported something the Miami condo market had not seen since 2023: coastal inventory actually fell. Condo listings in Miami Beach, Sunny Isles Beach, Bal Harbour, Bay Harbor Islands, Surfside, Fisher Island, and Key Biscayne dropped 13% annually to 3,919. That same report showed condo closings rising 15% to 693, the first increase since Q4 2024. Two numbers pointing in opposite directions: fewer homes available, more sales closing. That is the definition of a tightening market, and it has real consequences for what you pay and how fast you need to move. If you are trying to understand where coastal Miami stands right now and how to act, this is the breakdown. For the full pre-construction picture alongside resale, see the Miami pre-construction buyer guide and the North Bay Village luxury condos guide for the bay-front submarket absorbing five branded pre-construction launches as supply contracts.
The April 2026 Data: What a 3-Year Low Actually Means
The first thing to understand about 3,919 coastal condo listings is context. At the peak of the post-SB 4D supply surge in mid-2024, coastal Miami had more than 5,000 condos listed simultaneously. That wave was driven by owners facing mandatory reserve contributions and milestone inspection costs under Florida's condo reform legislation. That supply has now been absorbed. What remains is the actual demand floor, and it is lower than at any point since 2023.
According to The Real Deal (April 17, 2026), the data covers Miami Beach, Sunny Isles Beach, Bal Harbour, Bay Harbor Islands, Surfside, Fisher Island, and Key Biscayne. Key figures from the report:
- Coastal condo inventory: down 13% annually to 3,919 listings, the first annual decline since 2023
- Coastal single-family inventory: down 15% to 398 listings
- Condo closings: up 15% to 693, first annual increase since Q4 2024
- Single-family closings: up 13% to 85, first annual increase since Q2 2024
- Foreign buyers: 42% of Q1 2026 Miami condo sales, per NAR 2026 international buyer data
The combination of declining supply and rising closings is the signature of genuine demand absorption, not a speculative spike. Cash buyers from Latin America, Europe, and domestic high-net-worth relocators continued purchasing through 2024 even as inventory peaked. Now that supply has cleared, those buyers face fewer options. Before making an offer in any of these submarkets, see how to assess a Miami condo building's financial health before committing to a deal.
Coastal Submarket Breakdown: Where Supply Is Tightest
The 13% inventory decline is not evenly distributed. Bal Harbour, Fisher Island, and Key Biscayne face the most constrained supply due to geography and development limitations. Sunny Isles Beach has more listings but is also contracting. Here is how the key coastal submarkets compare as of April 2026, based on Q1 2026 Miami Realtors data:
| Submarket | Avg. Price/Sqft | Inventory Trend | Supply Constraint |
|---|---|---|---|
| Bal Harbour | ~$1,300 | Declining | Very high (2 primary towers) |
| Fisher Island | $1,500+ | Minimal listings | Extreme (island; resale only) |
| Surfside | ~$1,300 | Declining | High (Champlain-era restrictions) |
| Key Biscayne | ~$1,100 | Declining | High (island geography) |
| Sunny Isles Beach | ~$975 | Down 13%+ | Moderate (more towers) |
Surfside's average sold price reached $7,140,500 in Q1 2026, per MIAMI Association of Realtors, the highest of any Miami submarket. That reflects both limited resale supply and the ultra-luxury profile of the buildings that remain. Post-Champlain Towers, development permit restrictions in Surfside have kept new supply offline, compressing the resale market further. For international buyers comparing coastal submarkets, Sunny Isles Beach currently offers the best price-per-square-foot entry point relative to beachfront quality.
Why Closings Are Up 15% When Prices Stay High
The 15% rise in coastal condo closings to 693 in Q1 2026 tells a more important story than the inventory number alone. It shows that buyers are not waiting for prices to drop. They are buying anyway, because the drivers pushing them toward coastal Miami real estate have not changed.
The profile of buyers closing on coastal Miami condos in early 2026 is consistent with what I see from my Compass desk: cash buyers who made liquidity events in 2024 or 2025, Latin American buyers protecting wealth in a hard-asset outside their home currency, and domestic relocators who have already decided to move to South Florida and need a permanent residence rather than a vacation unit. None of these buyers are rate-sensitive in the traditional sense. A 6.2 percent 30-year mortgage rate does not stop a Venezuelan buyer wiring $1.8 million in cash or an Argentine buyer who sold a Buenos Aires apartment for dollars. Tax obligations on these purchases vary widely by country of residence, but the cash-deal pattern across Latin American buyers is consistent.
According to Miami Realtors Q1 2026 data, total Miami-Dade home sales rose 6.6% year-over-year, with condo sales in the $300,000 to $600,000 range up 7.1%. That midrange increase matters because it shows demand is not confined to the ultra-luxury segment. The coastal inventory decline affects buyers at multiple price points, not just those competing for $3 million penthouses in Bal Harbour.
The forward supply picture adds pressure. Related Group and Macklowe Properties recently secured approvals for two 43-story Ritz-Carlton branded towers in North Bay Village, with 364 units planned between them. Projects like this take four to six years to deliver. In the meantime, coastal buyers are competing for the existing 3,919 units. New supply is coming, but not quickly enough to change the near-term supply dynamic in established coastal submarkets like Sunny Isles or Key Biscayne.
What Buyers Should Do in a Supply-Constrained Coastal Market
Tightening inventory creates a decision point. Here is the specific action list I walk my clients through in this environment. For the longer view alongside this checklist, the Miami preconstruction buying process covers each stage from offer to closing.
Define your non-negotiables before searching. When inventory is declining, buyers who have not pre-clarified their building criteria waste time on units that do not fit. Is it waterfront views? Specific floor? HOA under a certain amount? Pet policy? Finalize the short list before contacting any seller or agent.
Get fully pre-approved, not pre-qualified. In a market where condo closings rose 15%, motivated sellers choose offers that are least likely to fall through. A full underwriting approval beats a pre-qualification letter in any multiple-offer scenario, and coastal Miami is now generating multiple-offer situations regularly on well-priced units.
Audit HOA reserves before offering. Florida's SB 4D reserves compliance has changed the true cost of owning a Miami luxury condo in older buildings significantly. A unit priced at $900,000 in a building facing $60,000 in pending special assessments costs more than a unit at $950,000 in a fully funded building. Understanding how SB 4D reserve mandates affect coastal Miami buildings and how to read a condo association's financial health is now a baseline buyer skill, not optional due diligence.
Act within 30 days of the right unit appearing. The average days on market for coastal Miami condos has been compressing since Q4 2025. Units priced correctly in Bal Harbour, Sunny Isles, and Key Biscayne are receiving offers within two to three weeks of listing. If you find the right unit, act. Waiting to see if something better emerges is how buyers in a tightening market lose units to faster competitors. Call me directly at (305) 964-8614 and I will pull current active inventory across all coastal submarkets with the reserve status already vetted.
"When inventory drops to a 3-year low while closings rise 15%, the math works against buyers who wait. My clients who identified a target building and acted in Q1 2026 are already looking at 5 to 8 percent appreciation. Those who said they would wait for better conditions have fewer choices today and are paying more for them."Gerardo Gonzalez, Licensed Real Estate Agent at Compass
