I sent you a private message with my realtor's information.
I am east of 17 in Myrtle Beach. My home is 3BR, 3 BA, single family and I spend about $1500 year including flood insurance. I'm not in a flood zone, just protecting my investment.
Vacation properties are taxed at 6% times a millage factor - here's an example from
Taxes NC and SC
Non-Resident Property Taxes:
Second home and investment property owners are taxed at 6% with millage rates that include a percentage imposed for school operating purposes and there is no relief available for age or disability. Keep in mind as you look at the example for a second home, vacation home, or investment that the property taxes are still considerably low.
Example based on $200,000 vacation / investment home assessed at 6% in an area where the millage rate is 228 mills. $200,000 x 6% x .228 = $2,736
Hope this helps
