Why Closing Cost results differ in South Carolina

The top 5 reasons results differ

Run this scenario in DocketMath using the Closing Cost calculator.

If you run the DocketMath Closing Cost calculator in South Carolina (US-SC) and notice your “Closing Cost results” don’t match someone else’s output, the cause is usually not the calculator—it’s the inputs and how they map to the tool’s jurisdiction-aware assumptions.

Here are the top 5 reasons results commonly diverge for South Carolina users:

1. **Different date assumptions (or missing dates)

   • Closing-cost totals often depend on timing inputs (for example, the settlement/closing date and any date-based expectations tied to amounts).
   • Even if two people believe they’re using the same scenario, one run may use different “effective” dates or omit a date the other run includes.

2. Mismatch in fees and who pays what

   • The same fee line can land in different totals depending on payer responsibility (buyer vs. seller vs. third party).
   • If one workflow assumes an item is buyer-paid at closing while another assumes it’s split or reimbursed later, the totals can shift.

3. Incorrect categorization of settlement items

   • The calculator groups costs into categories for computation.
   • If a user enters a cost under the wrong category (for example, putting a loan-related charge in a property-related line), the math can still run—but it may produce different results than another person’s correctly categorized inputs.

4. Interest rate / loan structure differences

   • Even small differences in loan terms can change calculated interest-related components and how they roll into closing costs—depending on the calculator’s inputs.
   • Compare side-by-side: principal amount, interest rate, term, and whether fees are financed into the loan or paid upfront.

5. Confusing “time” expectations with settlement-cost inputs

   • A common “logic leak” is using statute-of-limitations timing thinking (how long someone has to sue) as if it directly controls closing-cost totals.
   • In South Carolina, the general/default limitations period discussed in this brief is 3 years under GS 15-1. No claim-type-specific sub-rule was found, so this is the default only.
   • Closing-cost results can still differ when someone embeds a time-based expectation into other settlement inputs (or compares different document types).

Reminder (not legal advice): DocketMath produces outputs based on the inputs you enter. Two runs with different assumptions—even if both seem reasonable—can produce different results.

How to isolate the variable

To pinpoint what’s driving the difference, treat this like a diagnostic session. The fastest path is to control inputs and change only one variable at a time.

• Run the same scenario twice

  • Keep every field identical except one of: dates, buyer/seller responsibility, fee category, loan terms, or whether a fee is financed vs. paid upfront.
• Lock the “date set”

  • If you have multiple relevant dates (contract date, closing date, payoff date), choose one approach and apply it consistently across both runs.
• Confirm fee-to-category mapping

  • For each line item, verify it’s entered in the category the tool expects (loan-related charges vs. closing/service fees vs. other).
• Normalize responsibility

  • Ensure both runs reflect the same payer logic (buyer-only vs. split vs. seller-paid).
• Reconcile loan inputs

  • Compare interest rate, principal, and term fields between runs.
• Check “financed vs. paid” behavior

  • If a fee is treated as paid upfront in one run but financed into the loan in another, totals will diverge.

If you want to compare outputs efficiently, rerun the same scenario here: /tools/closing-cost.
Then, repeat the experiment—changing only one input each time.

Finally, if you think the mismatch is caused by “how long someone has” to bring a claim, separate that from closing-cost math:

• Closing-cost estimates: driven by settlement inputs.
• Statute of limitations logic: in this brief, South Carolina’s general/default period is 3 years under GS 15-1 (default only; no claim-type-specific sub-rule identified here).

Next steps

Once you isolate the variable, you can make your results consistent across people and documents:

1. **Create an input checklist (an “input checksum”)

   • Record:

     • the exact dates used (and what each date represents),
     • loan terms (principal/rate/term),
     • each fee line item and the category it was entered under,
     • who pays each item.
2. Align definitions with the other run

   • If you’re comparing against a worksheet or statement, confirm:

     • what the other source counts as “closing cost,”
     • whether points/loan fees are treated as paid upfront or financed.
3. Keep a short change log

   • Example:

     • “Run B used Closing Date = 2026-03-15 instead of 2026-03-01”
     • “Run B categorized fee X as lender charges instead of settlement charges”
4. Use SOL only for timeline decisions

   • For South Carolina, the 3-year general/default limitations period is GS 15-1. Use it for rights/timeline questions—not to justify different settlement-cost inputs.

Pitfall to watch: Estimates vs. settlement statements often use different definitions for similarly labeled line items, even if the categories “look” the same.
