Ownership and recorded sale history
What has actually traded in South Beach / Collins Avenue
Recorded transactions for retail properties in South Beach along Collins Avenue, Alton Road and Washington Avenue, narrowed to the buildings closest to this one in size and age.
Reading this against the corridor
The county assesses this building at $1,831/SF. Recorded sales of retail properties in South Beach / Collins Avenue since 2022 have a median of $876/SF, across a range of $288/SF to $1,969/SF.
Across those 8 recorded sales, the median sale price came in at 0.89× the county assessed value. Assessed values are set for taxation and are reset on their own schedule, so they routinely sit apart from transaction prices — in either direction.
By footprint it sits in roughly the 24th percentile of retail properties that have traded in this corridor — 42 of the 55 recorded sales were of larger buildings.
The assessment works out 109% above the median price per square foot of the comparable sales shown below. That is an arithmetic comparison of a tax figure against transaction prices, not a statement about what this building would sell for.
The lot runs 4.3× the building footprint — 17,080 SF of land under 3,935 SF of structure. Ratios that wide are usually where expansion or redevelopment questions start.
What this means for this building depends on what no public record contains — the leases, the condition, the rent roll.
