South Carolina Property Tax and Why Rentals Cost More
South Carolina assesses property differently depending on how it is used. For an investor that difference is a permanent line in the operating budget.
South Carolina does not tax all real property on the same basis. Assessment ratio depends on use, and investment property sits in the higher band.
The two ratios that matter
An owner-occupied legal residence is assessed at a lower ratio than other real property, which includes rental and investment property. The same building, at the same market value, produces a materially different tax bill depending on how it is occupied.
What that means for underwriting
- Never use the seller's tax bill if they occupied the property and you will rent it
- Re-estimate tax at the investment ratio before you calculate NOI
- The difference can be enough to move a marginal deal into a loss
Reassessment on sale
A change of ownership can trigger a reassessment to current market value, so a long-held property with a stale assessed value may carry a very different bill for you than it did for the seller.
Millage varies locally
The ratio sets the assessed value; local millage sets the bill. York, Lancaster and Chester counties are not interchangeable — check the specific jurisdiction and any municipal rates on top.
Get it in writing
Ask the county assessor for the treatment you should expect at your intended use, and budget the higher figure until you have confirmation.
