Common Closing Cost mistakes in South Carolina

The top mistakes
Run this scenario in DocketMath using the Closing Cost calculator.
Closing costs in South Carolina can feel like a jumble of third-party fees, lender charges, and prepaid items bundled into one settlement statement. DocketMath’s closing-cost calculator helps you model those numbers early—but mistakes usually happen before you ever enter data.
Below are common closing cost mistakes for South Carolina (US-SC), along with what to double-check in your file.
Pitfall: If you enter a “Loan Estimate” number as a “final settlement” number (or vice versa), your modeled totals can drift by hundreds of dollars—especially when prepaid interest, escrow items, or lender credits are involved.
1) Misclassifying prepaid items as lender fees (and vice versa)
A frequent problem is treating prepaid costs (like prepaid property taxes or homeowners insurance) as if they’re lender charges. That matters because:
- Some prepaid items can change based on the closing date (and sometimes the coverage/occupancy timing).
- Some lender/underwriting fees are typically fixed under the lender’s terms (unless the lender later changes them due to timing, lock expiration, or document revisions).
What to do in DocketMath:
Use the calculator inputs to separate categories (fees vs. prepaid/escrow-style items) instead of dumping everything into one bucket.
2) Forgetting that closing date changes prepaid interest (daily math)
Prepaid interest is often computed per day between:
- the settlement/closing date, and
- the next scheduled payment date.
If you use an estimated closing date and it slips by even a week, the prepaid interest line can move noticeably.
How this shows up in the tool:
In the DocketMath closing-cost flow, keep your settlement/closing date consistent with what you’re modeling. If the date is off, the output total can be off.
3) Omitting escrow/impound setup amounts (or entering them twice)
In practice, buyers sometimes:
- leave escrow setup blank, or
- add escrow setup once in “prepaids” and again in a monthly-escrow funding field.
Either error can swing your cash to close.
Checklist for data entry:
- Add escrow-related amounts only in the category that matches the settlement statement format you’re modeling.
- Confirm whether the statement is describing initial escrow funding versus future monthly escrow deposits.
4) Using outdated fee schedules or “locked” vs “unlocked” rates
Even without changing the loan product, lenders may adjust certain charges when:
- a rate lock expires,
- underwriting verification changes the file,
- timing differences lead to revised disclosures.
Tool impact:
DocketMath can’t know whether your lender changed fees after your estimate. Your accuracy depends on using the latest figures from your current disclosure/worksheet.
5) Counting credits incorrectly (lender credits are not always “free money”)
Lender credits can reduce some lines but create offsets elsewhere. Common mistakes include:
- treating the credit as a direct subtraction from the total without reflecting the related fee structure, or
- entering credits with the wrong sign (positive vs. negative).
How to avoid this:
Enter credits as they appear in your documents and the document logic. If the disclosure lists a credit amount, make sure DocketMath is treating it as a reduction, not an additional cost.
6) Overlooking timing concepts that affect later disputes (not the calculation, but the risk)
Closing costs themselves are generally paid at settlement. However, disputes or claims tied to settlement amounts can still come up later. For South Carolina, the general statute of limitations is 3 years under GS 15-1.
Warning: DocketMath modeling won’t determine whether a claim is timely. But if you’re tracking settlement amounts for later accounting, remember that South Carolina’s general default SOL is 3 years under S.C. Code Ann. § 15-1.

How to avoid them
You can reduce closing-cost errors quickly by using a repeatable workflow in DocketMath before you compare to final closing documents.
Use a written checklist for inputs, document each source, and run a quick sensitivity check before finalizing the result. When two runs differ, compare inputs line by line and re-run with one variable changed at a time.
Step-by-step workflow (practical, fast)
Use the right disclosure “snapshot”
- If you’re modeling from an estimate, label it as an estimate.
- If you’re modeling from a current worksheet, use those exact numbers.
Enter dates consistently
- Settlement/closing date (especially for prepaid interest)
- Any billing cutoff concept that affects prepaid interest
Separate fees from prepaids
- Lender/underwriting/origination style fees → one group
- Prepaid taxes/insurance/escrow setup → another group
Verify escrow/impound setup once
- If a line item says “initial escrow funding,” enter it only in the category that represents that concept.
Check credit math
- Ensure lender credits reduce the total in the way the disclosure indicates.
- If a credit appears, reconcile whether related lines should also shift.
Run two scenarios
- Scenario A: your planned closing date
- Scenario B: a “worst-case” slip (example: +7 days)
Then compare how the total changes. If the total is overly sensitive to date, inspect prepaid interest inputs first.
What to look for in the DocketMath outputs (sanity checks)
| Output change you see | Likely cause | Quick fix in DocketMath |
|---|---|---|
| Total changes a lot when you move the closing date | Prepaid interest (daily accrual) | Update/confirm closing date and prepaid interest inputs |
| Total increases when you add escrow setup | Escrow items entered twice or entered in wrong bucket | Remove duplicates; place initial escrow funding in the correct category |
| Total doesn’t drop when you add a credit | Credit entered as cost or wrong sign | Enter lender credits using the disclosure’s reduction amount |
| Total is close but still off by a consistent amount | Missing or miscategorized fee line item | Compare against your settlement statement line-by-line |
A short “data hygiene” checklist
Note (South Carolina SOL context): South Carolina’s general SOL is 3 years under S.C. Code Ann. § 15-1. This doesn’t change how closing costs are calculated at settlement, but it can matter when parties later dispute amounts tied to filed claims or recovery efforts.
