What is the biggest cost of living on Johns Island?

Housing itself is usually the largest ongoing cost of living on Johns Island, followed closely by property insurance, since flood and wind coverage on parts of the island run higher than on inland properties. Commuting costs also add up given Johns Island's distance from downtown Charleston during peak traffic hours. Brian Beatty can point out which specific pockets of Johns Island tend to carry lower insurance and shorter commute times before you commit to an area.
