Matthew Gigantelli's South Carolina Analysis
ASCSP Member M009-25 · Lead Cost Segregation Engineer
"South Carolina's tourism-driven coastal markets — Charleston and Myrtle Beach — produce excellent cost segregation results, particularly for STR and hospitality properties. Full conformity and a growing industrial base (BMW, Volvo manufacturing corridor) round out the opportunities. I especially like the Charleston market where historic renovation meets modern amenities."

How Cost Segregation Works in South Carolina
Cost segregation is an IRS-approved tax strategy that reclassifies components of your South Carolina property from the standard 39-year (commercial) or 27.5-year (residential) depreciation schedule to shorter 5, 7, and 15-year recovery periods. With 100% bonus depreciation restored under the One Big Beautiful Bill Act, these reclassified components can be fully depreciated in year one.
For South Carolina property owners, this means turning a $2.1M commercial property into $35,000 - $90,000 of first-year tax savings instead of waiting decades for the same deduction.
