Computed across the 8 sales listed below — the closest matches to this building by size and vintage. Transfers under $100,000, multi-parcel portfolio deals that cannot be allocated, and land-dominant parcels are excluded.

Reading this against the corridor

The county assesses this building at $547/SF. Recorded sales of office properties in Federal Highway Corridor since 2022 have a median of $501/SF, across a range of $343/SF to $724/SF.

Across those 8 recorded sales, the median sale price came in at 1.13× 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 67th percentile of office properties that have traded in this corridor — 5 of the 15 recorded sales were of larger buildings.

The assessment works out 9% 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 4.0× the building footprint — 20,755 SF of land under 5,194 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.
