Confirm the intended property use
For a South Carolina purchase, ask the local assessment office how your intended use is reflected in the quoted tax amount. Do not carry a primary-residence assumption into a second-home or rental scenario without confirmation.
Build the cash reserve alongside the payment
For a coastal address, request homeowners, wind and flood coverage details as applicable. Keep annual premiums distinct from one-time settlement costs. If the property has rental potential, this worksheet does not treat that potential income as guaranteed support for the mortgage.
An illustrative sensitivity check
An additional $1,200 in annual tax or insurance adds $100 to the monthly budget. An additional $75 in monthly association dues adds another $900 per year. These are arithmetic examples, not local averages. Change those fields independently to see whether the home still fits before adjusting the mortgage rate or term.

Questions, answered
Are the starting figures South Carolina averages?
No. They are illustrative inputs shared across the site. Replace tax and insurance with address-specific annual estimates and use an actual loan quote.
Where are the supporting references?
The linked property-tax and insurance guides contain the external references. This state worksheet uses internal links only.
