The top 5 reasons results differ

If you run the Closing Cost calculator in DocketMath for Connecticut (US-CT) and see different results than you expected, the difference is almost always coming from one of these variables. DocketMath’s jurisdiction-aware rules don’t change the arithmetic of closing costs—but they do change what claims or time windows remain “actionable,” which then affects the final output logic.

Note on SOL baseline (important): The General statute of limitations (SOL) used by default in Connecticut is 3 years under Conn. Gen. Stat. § 52-577a. In this dataset, no claim-type-specific sub-rule was found, so the 3-year general period is the baseline for the calculator’s SOL-related behavior.

Here are the five most common causes of mismatched Closing Cost results in Connecticut:

**Date mapping (when the “clock starts”)
- DocketMath needs to interpret the relevant date(s) you provide (for example: signing date, closing date, or a notice-related date—whatever you input).
- Even a 30–180 day shift can move a scenario from “within 3 years” to “outside 3 years,” which then changes downstream SOL-driven assumptions.
Assumed valuation window tied to SOL logic
- Because the default period is 3 years (per Conn. Gen. Stat. § 52-577a), results can change when your scenario lands near the boundary.
- Example: a deal near Jan 15, 2022 may behave differently depending on whether your calculations are effectively treated as occurring in Feb 2025 vs. Apr 2025 (i.e., the relative position to the SOL window).
Input mismatch: fees vs. reimbursements / prorations
- Closing costs often include items that function differently (e.g., standard charges vs. prorations/reimbursements).
- If you enter fee categories in a way that doesn’t match how the closing-cost calculator logic expects to treat those items, totals can differ even when the dates are correct.
Property/transaction type differences affecting what fields you use
- DocketMath can only calculate from what you enter.
- If the transaction context implies different escrow/lender-related items, but those fields are left blank—or the wrong ones are used—the output can shift.
Jurisdiction code not fully aligned with the scenario
- Connecticut-specific logic requires US-CT to be used consistently.
- If earlier runs used a different jurisdiction and you only updated some inputs, you may end up with a “close-looking” total that still doesn’t match what you expected.

How to isolate the variable

Use a short, structured comparison to find what changed between runs. This is the quickest path to diagnosis.

Freeze the jurisdiction and tool settings so both runs use the same rule set.
Compare one input at a time (dates, rates, amounts) and re-run after each change.
Review the breakdown to see which segment or assumption drives the difference.

A. Lock the jurisdiction and SOL baseline

Confirm the run uses Connecticut (US-CT).
Confirm the SOL behavior is using the general 3-year period under Conn. Gen. Stat. § 52-577a (not a claim-type-specific override). In this dataset, the 3-year general period is the default because no claim-type-specific sub-rule was found.

B. Run a controlled change test (one variable at a time)

Check these inputs first, in this order:

Relevant date(s): run once using your earliest reasonable date, then again using your latest reasonable date.
Closing cost line items: verify you didn’t double-count or omit prorations/escrows/reimbursements.
Category mapping: ensure each fee is entered under the intended category for the closing-cost calculator.
Transaction fields: confirm all lender/escrow-related items your scenario includes are present in the fields you used.

C. Compare outputs with intent

If the result changes sharply when you adjust dates, the most likely cause is the date-to-3-year SOL boundary based on Conn. Gen. Stat. § 52-577a.
If the result changes more gradually while you adjust dates, focus first on fee category handling and missing/extra line items.

D. Use a boundary test (fast)

Pick a date adjustment of ±90 days and re-run:

If results flip around the 3-year window, you’ve found the date-mapping variable.
If results remain stable, the issue is more likely inputs (line items or category mapping) rather than SOL timing.

For a fast re-run, start here: **/tools/closing-cost

Next steps

Document your inputs exactly as entered
- Save a screenshot or write down: jurisdiction (US-CT), the date(s) used, and each closing cost line item.
Reconcile the “operative trigger” date with your scenario
- Decide which date you want DocketMath to treat as the operative trigger for the 3-year baseline under Conn. Gen. Stat. § 52-577a (general SOL).
Validate category handling
- Confirm whether each item you included is a true charge or should be treated as a reimbursement/proration in your data entry approach.
Re-run after each change
- Adjust one thing at a time, then compare the delta. Your goal is to identify the single input that explains the difference.

Gentle reminder: This is not legal advice—SOL and how “operative dates” are determined can be fact-specific. Treat these steps as a practical way to debug calculator inputs and assumptions.
