Cost tools
All-in monthly cost for Charleston SC.
The mortgage payment is not the payment. Add property tax, HOA, flood, and wind. If you are closing near Sept. 30, 2026, watch the NFIP authorization date.
PITI is the start, not the number
A $450,000 house at 6.5% looks one way on a mortgage calculator and another once Charleston County tax, a $185 HOA, wind, and a flood policy land in escrow. Military buyers should run this next to the BAH calculator.
Flood quotes are yours to get. If you enter a flood premium, this tool flags the Sept. 30, 2026 NFIP date so a fall closing is not a surprise. Confirm zone on Check This Address. What a lapse actually does to a closing: NFIP Field Note.
All-In Monthly
Planning estimate · Charleston metro
You entered a flood premium. NFIP is authorized only through 11:59 p.m. Sept. 30, 2026 unless Congress extends it. Ask your lender what happens if authorization lapses around your closing date.
Insurance quotes vary by flood zone, wind mitigation, and carrier. Not a Loan Estimate.
