What the numbers say

On a $499,300 median home at 0.46%, property tax in Charleston runs about $191 a month ($2,297 a year). That is the single largest owning cost a renter never pays directly, and it is worth modeling before you compare.

The renting side starts at $2,163 a month, roughly $25,956 over a year. Home prices in Charleston have climbed fast lately, near 11.5% a year. The calculator still uses the long-run 3 to 3.5% national average, since betting on a hot streak holding is a common way short-stay buyers lose money.

Homeowners insurance is modeled at the South Carolina average of $1,700 a year; swap in a real quote once you have a specific home.

What makes the rent-vs-buy math different in Charleston

Charleston's price-to-rent ratio is about 19.2: the $499,300 median price divided by $2,163 a month in rent over a year. That is a mid-range ratio, leaving the rent-vs-buy answer to your down payment, mortgage rate, and stay length. The ratio is the fastest gut check on a market. It does not replace the full calculation, but it tells you which side of the decision starts ahead.

With the ratio near the national middle, neither renting nor buying in Charleston starts with a clear structural edge. The break-even year swings on your down payment, the mortgage rate, and rent growth, which is exactly what the calculator below resolves.

Seldom. A $499,300 home in Charleston carries about $19,972 in buy-side costs and $29,958 to sell, roughly 8 to 12% round-trip. Three years of price growth rarely makes that back, so for a short stay renting is generally the safer financial call, as in most U.S. markets.
