Why the Sunny Isles Beach Condo Median Is Falling While Sellers Get Closer to Asking

In the third quarter of 2026, the median Sunny Isles Beach condo sale fell 20% from a year earlier, to $683,000. Over the same quarter, more units closed, listed inventory shrank, and sellers gave up less off their asking prices than they had a year before. Together those figures describe a quarter in which more lower-priced units sold and fewer trophy units did, which is a change in the sales mix more than a broad drop in what a given unit is worth.

The building now matters more because of a rule change that took effect August 3. Since that date, a conventional loan on a condo in an established Sunny Isles tower goes through a fuller review of the association than it did in the spring. In practice, the lender is underwriting the building's reserves, inspections and assessments alongside the buyer.

The Q3 Numbers Don't Tell the Same Story

Here are the Q3 2026 closing figures for Sunny Isles Beach condos, co-ops and townhouses, set against the same quarter of 2025:

The average price fell further than the median, and price per square foot fell almost as far. That pattern points to fewer large, expensive units in the closing mix and more modest ones, and the narrower discount backs it up. A seller asking $600,000 for a well-priced unit in a financeable building can get close to that number even while the area's median drops.

The broader region points the same way. For the Miami Beaches region as a whole, which includes Sunny Isles Beach, Bal Harbour, Surfside and Miami Beach, Q3 2026 closings rose 13% and the median rose 6% to $630,000, while the average fell 10%. Across the coast, more units changed hands and fewer of them were at the top of the market.

Since August 3, the Loan Also Underwrites the Building

Fannie Mae and Freddie Mac announced the change on March 18, 2026, in Fannie Mae Lender Letter LL-2026-03 and Freddie Mac Bulletin 2026-C. For loan applications dated on or after August 3, 2026, the following changed:

1. Fannie Mae retired its Limited Review. Established projects that used to qualify for it now go through Full Review, or a Waiver of Project Review where the project is eligible. The expanded waiver applies to projects of 10 or fewer units.
2. Freddie Mac retired its Streamlined Review. Established projects now use Established Condominium Project review or Reciprocal Review, and qualifying projects may be exempt.
3. Where a reserve study is used in place of the standard reserve test, both agencies now require funding at the study's highest recommended level, and baseline funding no longer qualifies.

Almost every oceanfront tower on Collins Avenue has far more than 10 units, so the simplified routes that once fit many Sunny Isles purchases no longer apply. Fannie Mae's August 2026 FAQ adds two details that matter more here than anywhere else. A project that fails a mandatory structural safety inspection is ineligible until it passes. And a special assessment cannot stand in for the reserve allocation that Full Review requires. Under that rule, a building that covered a concrete or roofing project with an assessment may still fail the reserve test.

Buyers can't look up a building's status directly. Fannie Mae's Condo Status Finder is built for associations, their management companies and authorized advisors, and Fannie Mae doesn't publish eligibility decisions. It does say a prospective buyer can ask the HOA or a lender to check its tools for any identified eligibility issues. If no one asks, the answer reaches a financed buyer through the lender's review, which can come after the contract is signed.

January 4 Is the Next Date That Changes the Math

The same March announcements set a second date. For applications dated on or after January 4, 2027, the minimum replacement-reserve allocation under Full Review rises from 10% to 15% of the association's annual budgeted assessment income. Freddie Mac made the same change on the same date. An association that budgets 12% for reserves can pass Full Review today and fall short of it for applications dated January 4 or later. A contract signed in November with a loan application dated on or after January 4 would be reviewed against the higher standard if the loan uses Full Review.

State law sets its own reserve calendar. Under HB 913, which took effect July 1, 2025, the structural integrity reserve study deadline for qualifying owner-controlled associations moved to December 31, 2025. Associations whose milestone inspection falls due by December 31, 2026 may complete the study alongside it, but no later than that date. The Florida DBPR condominium inspections page lists the deadlines by building age. The December 2026 date applies only to buildings on that combined path. For a buyer, the fact that matters is whether a building's study is finished and what funding plan it set, because HB 913 requires the study to account for how the association funds its reserves, including through special assessments or loans.

Countywide prices reflect these rules. In Q3 2026, median price per square foot for Miami-Dade condo closings under $10 million fell 5.6%, from $315 to $297, in buildings more than 30 years old. In buildings under 30 years old it fell 1.8%, from $585 to $575. Those are county figures, not a Sunny Isles series, and they compare different units rather than the same apartment twice. They are consistent with a market that is discounting older buildings faster.

Cash fills part of the gap. In August 2026, 50.5% of Miami-Dade condo and townhome closings were paid in cash, up from 48.1% in August 2025, according to MIAMI REALTORS. A unit in a building that can't pass lender review sells to a smaller group of buyers, and a smaller group of buyers sets a lower price.

The Floor Under the Oldest Buildings Is the Land

At the oldest end of the market, a building can be worth more as land than as a condominium. In July 2025, Related Group, Dezer Development and BH Group closed a $131.8 million purchase of the remaining 100 units at Miami Beach Club, a 108-unit, two-story building from 1951 at 19051 Collins Avenue, The Real Deal reported. That works out to about $1.32 million per acquired unit, close to twice the Q3 2026 Sunny Isles resale median.

The city commission approved a 62-story, 145-residence replacement tower by a 4–1 vote in February 2026, the Miami Herald reported, with a sales launch expected in early 2027. The developers' filing anticipated completion in December 2031, according to The Real Deal. The City of Sunny Isles Beach approved-developments page still lists the project as Miami Beach Club and includes an approved temporary sales center.

This kind of exit needs a low-rise building on a large oceanfront lot, which most aging Sunny Isles towers aren't. For a typical older high-rise, value still depends on reserves, inspections and whether a lender will approve the project.

The Newest Product Isn't in the Resale Numbers Yet

The quarterly median also leaves out new construction, because no Sunny Isles tower delivered in 2025 or 2026. Bentley Residences at 18401 Collins Avenue, Dezer Development's 216-unit tower, had reached about 13 stories by August 2026, and completion is expected in 2028, Florida YIMBY reported. In November 2025, its remaining units started at $5.8 million, The Real Deal reported. At The St. Regis Residences, 18801 Collins Avenue, Fortune International Group and Château Group finished the South Tower foundation in late July 2026, with remaining homes starting at about $5 million, according to a separate Florida YIMBY report.

Completed luxury product still trades at the top. In September 2026, The Real Deal reported a $33 million sale of the 52nd-floor penthouse at Estates at Acqualina, 17975 Collins Avenue, which it called the building's record.

Taken together, Sunny Isles has three condo markets under one median: resale in buildings that pass lender review, resale in buildings that depend more on cash buyers, and pre-construction priced from about $5 million that won't show up in closing data until the towers deliver. A buyer comparing a unit to "the Sunny Isles market" needs to know which of the three it belongs to.

What to Ask About a Specific Building

• Has the association completed its structural integrity reserve study, and what funding plan did it adopt?
• Where does the milestone inspection stand, and are any safety-related repairs still open?
• What share of the current budget goes to replacement reserves, and will it clear 15% for loan applications dated on or after January 4, 2027?
• Are any special assessments approved or pending, and how are they being funded?
• Has a lender completed a project review on this building since August 3, 2026?

Across Miami-Dade, sellers of existing condos received 94% of their original asking price in September 2026, with 12.3 months of supply and a median of 67 days to contract, MIAMI REALTORS reported. At 12 months of supply, buyers have time to ask these questions before they make an offer.

FAQ

Did Sunny Isles Beach condo values drop 20% in 2026? The Q3 2026 median fell 20% from Q3 2025. Closings rose 15% and the average discount from asking narrowed over the same period, which points to a shift toward lower-priced units in the sales mix more than a broad decline in what a given unit is worth.

Does the August 3 change affect cash buyers? The Fannie Mae and Freddie Mac project review rules apply to loans those agencies buy. A cash purchase skips that review. The building's reserves, inspections and assessments still affect what the next buyer, who may need a loan, will pay.

Is December 31, 2026 the statewide condo deadline? No. Under HB 913, December 31, 2026 applies to associations completing a structural integrity reserve study alongside a milestone inspection due by that date. The general study deadline for qualifying associations was December 31, 2025.
