A real $3.4 million assessment, a real mortgage, and the math that is pushing owners out of the units Surfside reform was meant to protect.
By Jose Navarro, MBA | The Navarro Report
MIAMI. Roughly 90 percent of Florida’s 1.6 million condominium units are now more than 30 years old, and the state’s post-Surfside reserve funding deadline has already passed. The bill for that overdue maintenance is arriving in a specific, calculable form: a special assessment on top of a mortgage payment, in a market where both are already more expensive than they were three years ago.
Start with the numbers that frame the problem. Condo association insurance costs have risen 103 percent since June 2022, and individual unit owner insurance is up nearly 28 percent over the same period, from an average of $1,342 to $1,715 a year. Senate Bill 4-D, passed after the 2021 Surfside collapse that killed 98 people, now requires buildings three stories or taller and 30 years or older to complete structural inspections and fully fund their reserves rather than defer maintenance indefinitely. That law is working as intended. It is also producing bills many owners cannot absorb.
A real case in West Kendall shows how the arithmetic actually lands on a household budget. The Heron, a 28 building community in Miami-Dade, approved a $3.4 million special assessment to cover roof repairs, waterproofing and structural work required by the county’s mandatory 40 year recertification process. Owners were given two ways to pay it. The lump sum option ran $13,200 per unit, payable in quarterly installments of $3,300. The financed option added $154 a month per unit for 10 years, on top of the $260 a month owners were already paying in regular condo dues.
That financed option is where the mortgage has to enter the picture, because an assessment loan does not replace a mortgage payment, it stacks on top of one. Take an older Kendall area condo of the kind now flooding the under $100,000 price tier, a segment of the Miami-Dade market that has doubled in listing volume year over year as owners who cannot carry rising costs choose to sell rather than refinance their way through an assessment. A $95,000 unit bought with 20 percent down carries a loan of $76,000. At today’s 30 year fixed rate, which averaged 7.28 percent as of October 1, 2026, the highest level since November 2023, that mortgage payment runs almost exactly $520 a month.
Add the Heron’s $260 in ordinary dues, and the pre-assessment monthly housing cost for a comparable owner is about $780. Add the $154 a month assessment loan payment, and the same owner’s monthly outlay rises to roughly $934, a jump of nearly 20 percent, before counting homeowner’s insurance, which has itself climbed by double digits over the same stretch. For a household already stretched by a 7 percent-plus mortgage rate, a 20 percent increase in combined housing cost is not a rounding error. It is the difference between staying and selling.
The market is already showing that choice being made at scale. Older condo sale prices in South Florida fell 21 percent in 2024 compared with the year before, and some analysts project a further decline, from roughly $379 to $231 per square foot, as more owners face the same decision the Heron’s residents faced in 2025. The result is a split market: units priced above $1 million rose only 25 percent in volume, while units priced below $100,000 doubled, meaning the owners most exposed to a special assessment are precisely the ones with the least room to absorb one, and they are exiting the market rather than financing their way through it.
Legislators have made incremental adjustments since SB 4-D passed, including provisions letting some associations phase in reserve funding, but reporting on the most recent session found no substantial new relief for owners already facing assessments on the books. The deadline that triggered this wave of bills has passed. The relief that might have softened it mostly has not arrived.
None of this argues for abandoning structural safety requirements adopted after a building collapse that killed 98 people. It argues for treating the cost side of that policy with the same rigor as the safety side. Two disclosures would help. First, counties approving 40 year recertification work should require associations to publish both payment options, lump sum and financed, with the full 10 year financing cost shown in dollars, not just the monthly figure, so owners can see what the loan actually costs them. Second, state or county housing agencies should track how many older condo units are selling specifically because of an assessment, data that does not currently exist in usable form, so policymakers can measure the human cost of the deadline they set.
The Surfside law was written to prevent the next collapse. It was not written to manage the next wave of foreclosures and distressed sales among owners who did nothing wrong except buy into a 40 year old building before anyone required its reserves to be real.
