How do Charleston flood and storm dynamics affect spec home underwriting?

Coastal Charleston requires required NFIP and excess flood coverage at close, plus wind mitigation features verified at appraisal. Builders working in V and AE zones should expect tighter ARV reflecting insurance cost and flood-zone comp sets. Inland Berkeley and Dorchester sites face less insurance friction.

Are bank construction loans still active in Charleston spec lending?

Yes. South State Bank and a handful of regional players anchor sponsor relationships at 70–75% LTC. Private credit picks up the 80%+ tier and any deal needing faster closing. Charleston's smaller local banking market means out-of-state sponsors typically lean on private credit more than in larger Southeast metros.
