How much is a monthly mortgage payment in South Carolina?
Here's a worked example for South Carolina. On a $400,000 home with 20% down ($80,000), you'd borrow $320,000. At a 6.55% 30-year fixed rate — the current U.S. national average — the principal and interest come to about $2,033 per month. Adding South Carolina's average effective property tax of 0.49% ($1,960 a year, or $163 a month) brings the core housing cost to roughly $2,196 per month, before home insurance and any HOA dues.

Conforming loan limits in South Carolina — when you cross into jumbo
Limits are set county by county, not state by state. For 2026 the national baseline is $832,750; above your county's limit you're into jumbo territory.
South Carolina is straightforward here: all 46 counties sit at the national baseline of $832,750. There are no high-cost designations anywhere in the state, so the same threshold applies whether you're buying in a metro or a rural county. With 20% down that's a purchase price of roughly $1,040,938 before a conventional loan becomes a jumbo — above most of the state's market, so relatively few South Carolina buyers hit it.
